The instantly with greater pressure of be issued to lower levels grows in compressor whole, the rise of market of the machine that do not have oil is potion undoubtedly can the strong heart needle of hearten prices, change competitive additional monarch to path for company diversity. According to not complete count, china did not have the total shipment volume of oily air compressor to be close to 5000 2018, but basically be forestall of place of foreign capital brand, chinese · China, China held the market share that exceeds 50% twice. So, other company wants to make a contribution somewhat in domain of the compressor that do not have oil, must why is li Qing Dynasty planted does the machines and tools of the form that do not have oil have economic feasibility? Does market demand have after all how old? Where is technical difficulty? Is the user bred degree how? …… this a series of problems.
For this, production factory of compressor of China of Shanghai of our specially invite (abbreviation: China) , industrial production factory of Shenzhen China Asia (abbreviation: China) , Chinese compressor makes (Shanghai) production factory (abbreviation: China) , China produces engine system (China) production factory (abbreviation: China) , production factory of Guangdong China science and technology (abbreviation: China) , production factory of Shanghai Shen Hangjian compressor (abbreviation: Shen Hangjian) , Zhejiang outstanding can compress equipment production factory (abbreviation: Outstanding can) , Shanghai case Lan Kelin (group) production factory (abbreviation: Gelankelin) , casting of essence of life of family of Ao Fu Er is mechanical (elder brother hill) production factory (abbreviation: Aofuerke) the representative compressor that do not have oil is had outside waiting for China company high level, will examine the technology of the machine that do not have oil, product, user and market through different perspective, do not have the market of oily compressor and direction with searching those who suit his for everybody!
Potential of the machine that do not have oil is tremendous but need benign competition
As a result of market account, major compressor business the sale 2019 and order case appear of different level glide, but as ” China is made 2025 ” the inspiration that development is advanced and Sino-US trade friction gives the near future us, more and more manufacturing industry leader realize the product standard that promotes his, from primary treatment to value catenary high end transition is the company can grow continuously surely the road of classics. In this big setting falls, high quality compressing air to be sure is the development content that prospective manufacturing industry reduces air demand can anticipate.
Meanwhile, in recent years, because environmental protection, provision is safe the policy requirement that waits for a respect is stricter and stricter, the environmental protection of people and safe consciousness are stronger and stronger also. In new policy how-to below, compressor of type of screw of traditional fuel injection already cannot satisfy the use requirement of special industry, reach new energy industry to medical treatment, food especially, ask compressor must realize lube 0 discharge.
No matter be,set out from tighter and tighter environmental protection policy, still be opposite from the user compress air taller and taller clean spend a requirement to look, the machine that do not have oil has wide market perspective. So, china and China are same, although discretion is very hopeful however,do not have mood of oily machine market to what did not come.
And observe according to Gelankelin, early the Euramerican before a lot of years machine that do not have oil and scale of screw of general fuel injection achieve 1: 4; The scale of day Han market is close to 1:3 even, and the machine of China that do not have oil takes whole market only at present 1% less than. Together with, homebred the machine that do not have oil progresses at full speed on character and research and development, product function is stabilized stage by stage. So, gelankelin thinks, the machine that do not have oil is one of mainstream direction of prospective compressor market, market share will increase considerably.
China also the company thinks, discharge to gas pure degree of operating mode environment that has a demand, the machine that do not have oil will be become surely option. Because of the technology progressively maturity will reduce product cost effectively (the cost after including sale price and carry out) the stability that increases a product to move, the meeting is so first after the client consideration can the product do not have oil with much better effect, this will enlarge the market demand of product of the machine that do not have oil undoubtedly.
However, we also should see, market of current the machine that do not have oil and the technology that what differ before is the machine that do not have oil not just, product, manufacturer, price, pattern of gimmick of method of its sale train of thought, competition, operation, profit also shows a new sign, contain the flavor of market of strong machine of pneumatics of fuel injection screw.
China thinks the quality that does not have oily machine product at present is uneven, price competition is too intense, this is not industry development long plan. Really, without the enterprise of core technology, follow suit blindly making small market value is won’t long, can affect the sale environment of whole market instead. So, shen Hangjian is initiated, want to promote relevant industry oil to pollute check mark to allow, make product of screw of user override small oil.
Outstanding can express, water is at present lubricant compressor of the screw that do not have oil is everywhere, certain manufacturer with low, the means that uses in vain even lets a client be used first pay again, disturbed badly market of the machine that do not have oil. Some clients for the graph temporarily cheap, low bought the machine that do not have oil, the result is not used, change for many times lead plane, solid belong to impolicy. China also expresses, water screw does not have doorsill of oily machine research and development relatively inferior, reason has more manufacturer to participate in competition, but whether can its product undergo time test, still wait for examine.
Oily to be not being had at present machine the current situation of blossom everywhere, china is done not have however too much and anxious. China thinks, this phenomenon returns mere consist in at present lubricant screw mixes of all kinds water to wait for the compressor category with production relatively inferior precision without oily vortex, and these two kinds of products are mixed in air quality oily screw compressor still can be not had with dry type on effect have certain difference. And, because market space is limited, dry type is thrown without oily product early days tremendous, low, cycle grows investment return rate, traditional and centrifugal equipment measures domain expression to be like person meaning very much again in narrow-minded. So, dry type does not have market of oily screw compressor at present still by a few main international compressor brand is occupational.
Of course, also the enterprise thinks, quantity of present the airframe that do not have oil is returned actually small, some do not have oily aircraft manufacturer to be sold to cooperate battalion, exaggerated sales volume and market demand intentionally.
The machine that do not have oil is elected to choose be reason to lift
Although do not have oily machine market to have wide market perspective and demand latent capacity, but, regard terminal as the user, take in faintly of a few standards, it is to use fuel injection to compressor filters again or use the machine that do not have oil directly after all, it is the thing that a your person headaches very, buy machine price difference after all very big really, the user needs to be in charge of for cost. To this, numerous compressor business sets out from technology and economic feasibility, the answer that gave out to unite: Depend on client demand and choice preference. Namely in the process that terminal user is purchasing pneumatics aircraft, need consideration equipment is whole all application link is opposite lifecycle compress air resid part bear degree.
China thinks, be in technical respect, fuel injection compressor did not replace the possibility of the machine that do not have oil truly. It is OK that machine of theoretic fuel injection deploys proper multistage to filter the “ that achieves ISO8573 does not have oily ” parameter, but the premise that this kind of possibility exists is: 1. Filter configuration is enough much; 2. Filter can develop the property that its allege; 3. When the processing capability of filter drops can change in time filter core. And actual condition often was to configure multistage to filter system, but because lack is safeguarded,wait for a circumstance, cause what use for long to compress air pipeline inside oiliness, final these oil are tasted was being contacted directly again ought to be not to have oily air to use a site originally, this pair has is not acceptability for the client that reduces air demand without oil truly.
Look from economy respect, fuel injection compressor replaces the machine that do not have oil wasteful also. Although from first system of the fuel injection on investment is a few smaller than wanting without oily system, but from defend point of view, and after multistage filters pressure loss and in light of brought energy loss, this is brushstroke “ inside the whole lifecycle in compressor not the buying and selling of ” of be to one’s profit. So, china suggests to need not to have oily airy user to choose not to have oily machine directly truly, do type not to have oily screw especially compressor of centrifugal perhaps type.
The point of view with same hold of case Lan Kelin, it is current above all still immature to abandoning the processing technology of oil and oil gas, it is cost cost next too big, the use cost house of later period is tall, for example changes often the matters concerned such as filter core, alumina, go up directly so the sensible choice that the machine that do not have oil is a get sth done once and for ever.
China also thinks, the purpose that will obtain devoid oil through filtering is very difficult and wasteful. After fuel injection machine uses an aftertreatment, gas source character can accomplish ” of “ small oil, satisfy the use of general requirement. But as more and more slashing to enraging source character to ask, the handles ability, dependability, maintainability demand to aftertreatment equipment is higher, this kind has oil + the component that filtering means establishs ties on one hand is much, trouble spot is much, meet those who bring dependability, security inevitably reduce; On the other hand, the use cost that handles equipment rises, filter ability inadequacy cannot achieve a requirement even, economy is poor. Consequently, it is to use fuel injection + the means of the aftertreatment, still use the machine that do not have oil directly, the standard of judge depends on the client demand to gas source character. On existing technology setting, use double screw water lubricant compressor can yet be regarded as a kind namely economic environmental protection, efficient and reliable means.
The reason that China suggests to use the machine that do not have oil directly is simpler —— air quality more get credit, the chemical composition of the generation in need not filtering to fuel injection is afraid.
Set out from client angle with other company different is, outstanding can think to appear type selecting is confused, because a lot of need do not have the terminal user of oily machine,be by misdirect of empty press salesperson. For instance some pharmacy business compresses air oil heft is very tall, back end of fuel injection machine adds how many filter to be done not have, still put in a large number of oily cent, bring about did not pass GMP attestation. Have to, this pharmacy company changed with the machine that do not have oil in succession fuel injection machine changed fuel injection machine.
Water lubricates to rise abruptly without oily double screw the technology waits for maturity
Shanghai international compressor was exhibited 2018 on, ten enterprises happen to coincide exhibited water is lubricant without sample of machine of pneumatics of oily double screw, lifted a water lubricant double screw is heated up without oil, temporarily between become the heat inside course of study to discuss a topic. To this, approve of person those who have, anti has, wait-and-see person Yi Youzhi.
China thinks water lubricates to have better market prospect without machine of pneumatics of oily double screw, its advantage is gas pure degree taller, but machine stability is at present poorer. With Chinese viewpoint likeness, aofuerke expresses, double screw water is lubricant on the market pneumatics machine has 10 enterprises to be in now development, the part been sellinging, defect is technology, product immature still. If technical maturity still has space of very big market,replace a part to have oily opportunity. China also thinks, water is lubricant machine of double screw pneumatics is a kind of product that complies with market demand, but doubt of existence of water quality management, this also is to restrict the issue of one big key that lubricant screw machine extends water.
Lubricant to water without machine of pneumatics of oily double screw, shen Hangjian and Gelankelin all support wait-and-see attitude. They think, water lubricates to apply cycle without machine of pneumatics of oily double screw now shorter, temperature and can effect problem fails to be solved thoroughly, technical maturity degree and can effect level needs to be in after comparativing for some time, ability and user form consensus.
Outstanding can be thoroughly negative to its: Water of “ double screw lubricates to press machine basis without oily sky the feedback of abroad and Chinese client, not be very good, product maturity is insufficient, fault rate is extremely high. My company has before an abroad agent do double screw water machine of the lubricant pneumatics that do not have oil, what sell at the beginning is very good, client satisfaction is spent very tall also. But, water of double later screw lubricates to press occurrence issue of machine big batch without oily sky, bring about a client to be done dead one by one, their company still is put now have a large number of before the double screw water of some brand is lubricant main engine of the aircraft that do not have oil. Even their company cannot make the machine that do not have oil, once the client knows company name says not to want, must register new company afresh later. ”
China special however value this anew to promote a technology, china thinks, doing type not to have compressor of oily screw type is to appear type of the earliest the aircraft that do not have oil, also be shipment amount is the at present largest kind in 3 kinds of type. But have dry type to existing to discharge Wen Gao, fault rate without oily technology tall, efficiency low, care and maintenance and cost are high wait for defect, client “ won’t be used, with do not remove ” . Odd screw water is lubricant the inadequacy that compressor made up for dry type not to have oily machine on certain level, be in the compressor do not have oil 2018 cuts a figure on the market. Odd screw water lubricates not to have oily photograph to compare with dry type, definite advantage is had on efficiency, dependability, but its defect is astral annulus piece for easy wear away, capacity quickens attenuation as time, and odd screw needs use Che Xi compound, machine man-hour long, efficiency is low.
Suffer macroscopical policy to guide on one hand, be based on on the other hand homebred turn the current situation that leads forestall of low, foreign capital, price of whole of the machine that do not have oil is high, and have dry type to existing without oily technology at present fault rate tall, efficiency low, care and maintenance and cost are high wait for defect, so eye comes round to look, double screw water lubricates is style of a kind of when have perspective most type that do not have oil. The GS series water that exhibits with China lubricates to be without compressor of oily double screw exemple, it has the efficiency that comparatives with fuel injection screw, outclass does type not to have oily compressor; The problem of nonexistent efficiency attenuation, the structure is simple Yi Weixiu, economy is best, shape grinding work art is mature, foreground very value.
Difference of different product development shows way
Although had made clear future of the machine that do not have oil but period market prospect, but the form that because do not have oily machine to also have a lot of,differs, feasibility of discretion of technical difficulty, cost, economy each have different, fit direction of oneself product type, technology certainly so, search the market to break through a dot, ability makes the professional work of the engine that do not have oil of each enterprise is advanced rise get twice the result with half the effort.
Current, the screw of China that do not have oil, piston, vortex, product line is relatively complete, the client reacts character is stabilized, the price is more expensive nevertheless. Next, china will comply with market demand to develop more and new-style product.
Major of division of abstruse husband Er does odd screw water lubricant lead plane, from 7.5kW ～ 315kW, 0.8 ～ 45m3, 3kg ～ 40kg, lead plane stability is good. Selling way is lubricant lead plane mixes water overall OEM, so the company plans to make odd screw overall stick a card for pneumatics mechanic factory. The reasonable development limits of oily to notting have machine (integrated technology element and economic benefits) , aofuerke thinks, vortex machine is in with the piston that do not have oil 11kW less than, odd screw water is lubricant in 15 ～ 132kW, dry type is in without oily machine 55 ～ 315kW, 315kW above is the optimal domain of centrifugal compressor.
Product of Gelankelin that do not have oil includes: A. Water is lubricant machine of pneumatics of screw of the low pressure that do not have oil, 2 ～ 5 kilograms, low pressure 2 kilograms (only course) the use requirement that can satisfy industry of a lot of fractionize, energy-saving and efficient, user report is wonderful, be in especially craft gas industry; B. Only course lubricates 16 kilograms without grease screw pneumatics machine, can satisfy the requirement using gas of laser cut industry, solve the problem that use gas effectively for the client, the high cost that the equipment after decreasing brings, use effect is admirable.
Outstanding can current advocate water of series of CM/B of the Mai En that push laborious is lubricant compressor of air of lever of the Chan Luo that do not have oil, its characteristic includes: A. Power comsumption province, produce tolerance big (same power increases gas to measure 15 ％ above) ; B. Efficiency is tall, only course is highest exhaust pressure 1.6MPa; C. Do not have oily safeguard absolutely, obtain German TüV to detect 0 class do not have the orgnaization oily attestation, a bit lubricating oil is not contained in lead plane; D. Extremely low maintenance charge (bad news material has water, water to filter only core, air filter core) ; E. Service life of train in excess specified length, use cost lowest; F. Low noise, without vibration. Get pharmacy, provision, ferment, the height of user of industry of hospital, electron, empty classify reputably. Additional, research and development of initiate of company whole world, appeared on the market CM/G series middling pressure does not have oily screw compressor, at present already company of many large group blows bottle client using.
China is newest roll out GS series to lubricate without grease machine of double screw pneumatics, capacity limits 1 ～ 25m3/min, exhaust pressure 0.5 ～ 1MPa, power paragraph 7.5 ～ 132kW, included 11 products type, its characteristic is OK end is “ 6 sexes ” . A. Jing Yin sex. The oscillatory noise of lead plane is extremely low, bare chance noise relatively fuel injection screw is low 5 ～ 10dB, overall noise is lower, very the spot that is helpful for improving a client uses an experience; B. Environmental protection sex. Distinguish at before the compressor of type of gush water screw that compresses antrum of antrum gush water, bearing to offer oil, no matter the lead plane of machine of GS series pneumatics is to be in compressing antrum or bearing antrum is water supply lubricant, whole system does not have lube completely, put an end to the pollution enraging a source that lube brings from the principle, it is the compressor do not have oil on real significance; C. Dependability. The structure is simple, athletic part is little, not fragile, made sure from structural design compressor has very high reliability; Additionally inferior exhaust temperature also reduced the mechanical failure that high temperature causes, the on the safe side that is helpful for equipment moves; D. Security. The cooling action as a result of gush water and the limitation that did not have dew point of upward pressure of fuel injection machine, water is lubricant the exhaust temperature of compressor is extremely low, compare environmental temperature only commonly tall 10 ℃ , and after fuel injection screw and dry type do not have oily compressor to be passed in exhaust cold hind temperature still is close to 100 ℃ . Extremely low exhaust temperature is helpful for the promotion of systematic efficiency on one hand, the moving safety of the person safety to handlers and equipment is very advantageous on the other hand; E. Maintainability. GS series water is lubricant structure of pneumatics aircraft main engine is simple, the part that need upholds is little, tear open outfit is convenient, facilitate safeguard and maintain; F. Economy. When user of lubricant pneumatics machine uses GS series water, do not need to cheer on one hand, managing many use cost. On the other hand, maintain commonly content needs to change only water filter, empty filter, maintain cost is extremely low.
The product must upgrade breed the market to approbate degree
Although, up to now China does not have oily machine market small already successful, but China thinks, the acceptance of the machine that do not have oil is spent inferior still, the stability that its reason is running at the machine all poorer, cost of the maintenance after carry out is higher, so the road of break out of an encirclement depends on upgrading products plan.
Gelankelin also thinks, cost of cost of the opportunity that do not have oil is high, of the market approbate degree had not reached expectant peak value. So, produce a business as the machine that do not have oil, want to must accomplish product quality to stabilize, perfect business management and type, raise the market to be opposite of the machine that do not have oil approbate degree. Current, the new product research and development of the company basically is in in high-pressured screw does not have oil two class are compressed above.
Outstanding what can think development potential is the greatest is water machine of the lubricant screw that do not have oil and compressor of the vortex that do not have oil. At present the market approbates degree of not tall reason to its is the costly case that the client cannot accept the plane that do not have oil, even some of enterprise knows pneumatics machine can use water to lubricate far from. As a result of outstanding can main client group is in pharmacy industry, hospital, food, blow bottle, electron, ferment wait for an industry, so outstanding can enter relevant field actively exhibit meeting, strive makes more client understanding water lubricant do not have oily compressor.
Lubricant to the water that the company values quite at present odd screw does not have oily pneumatics machine, shen Hangjian thinks, although market self-identity degree is not less than early days promotion, but still have a lot of clients more product of screw of self-identity dry type, also mean its technology promotion to still be done not have perforative to all application domain. The person of the same trade is additionally too much, product quality is uneven, low competition runs amuck, the user product promotion that so Shen Hangjian plans to hold more application industry is met, make the otherness of oneself product the biggest hard change, include product construction quality of reasonable and concise, performance is superior reliable, function is powerful and comprehensive, energy-saving effect industry is banner wait.
China thinks, compressor of lubricant double screw comes to water at present style of a kind of when although be have perspective most,look type that do not have oil, but the product that still does not have mature batch to change in China now puts in the market, to Chinese compressor industry or burgeoning technology. So, adverse element basically depends on user group little, market information feedback is insufficient, client have no way understands. Regard production as the enterprise, china is in thorough research and development while, the quality that pays attention to a product more and economy, increase new product market to popularize strength, popularize in the application of new industry, new field especially.
The half an year after this year comes next year, respect of research and development, china will be on the foundation of the existing technology that do not have oil, thorough development, perfect water is lubricant of pneumatics machine model chart, augment pressure limits, roll out water machine of lubricant high pressure, water is lubricant 2 class compress a technology; Popularize a field, the company will exhibit the respect such as inn of channel of meeting, distribute, experience through the industry, enrage the special industry with source character extremely high demand in the light of a few pairs especially, wait like industry of appearance of chemical industry of medical treatment, craft, accurate instrument, food, have specific aim undertake popularizing.
