Editor's note: We are in the process of use compressor, mix normally to achieve efficient manufacturing purpose, most moment, the option that we grant lead plane and spare parts and care and maintenance will be a bit morer, and understand and hold what often ignored the condition that waits for respect of a few detail to security however. Notice, levee of “ a thousand li destroys ” of Yu Yi acupuncture point, look be like is a small issue, if carelessness does not add an attention, not only can create needless waste, can lead to important matter reason one day eventually even. So, in compressor moving process, the problem no matter size, need to try to take seriously solve with fathom, this is the premise that makes sure compressor can hold safe and effective job.
So, we are being produced with enterprise and user to compressor each type reserves in the process the opinion of the view of machine and pertinent question is jumping-off place, the viewpoint that initiates the personage inside course of study is collected and discuss greatly, in an attempt to discusses mutual beneficial purpose in all. This period forum, we come to the intense discussion that what spread out to this listen to netizens.
Participate in extensively, sincerity communication, a lot of difficulty and problem are met be readily solved, this is the force of the network.
The welcome lands forum of industry of Chinese compressor network: Http://bbs.compressor.cn
About piston, centrifugal type and screw type 3 kinds of compressor, in moving allegedly, piston must consider to reserve machine, because it is fragile many, be about to safeguard from time to time, overhaul time interval is short, and screw type does not need to consider to reserve machine, centrifugal type also does not need, be such? Side others does a type type selecting to seek advice, consult everybody to have the teacher of experience.
The individual feels, centrifugal need not have normally machine, screw machine has equipment opportunity certainly, entrance piston must not have machine, but homebred piston machine must have machine oh.
Be such, in abroad general centrifugal need not have machine. But this configuration is relative, configure double oily filter for instance, need not stop machine is OK change the filter taking energy of life of filter core is waited a moment. In China average client or meeting consider equipment aircraft. Screw opportunity must have equipment opportunity, piston also should want to consider equipment aircraft!
Why don't I understand to must have equipment opportunity with screw machine?
It is below below cite the speech of “liuyao” : Be such, in abroad general centrifugal need not have machine. But this configuration is relative, configure double oily filter for instance, need not stop machine is OK change the filter taking energy of life of filter core is waited a moment. In China average client or meeting consider equipment aircraft. Screw opportunity must have equipment opportunity, piston also should want to consider equipment aircraft!
This also wants those who divide a case, if run the more than 8000 words of the hour every year,want equipment chance.
Should treat what craft condition actually, we had moved 7 years in used screw machine (meantime did not undertake medium, overhaul) , this machine also did not affect craft to produce without equipment platform! Additional even if entrance piston compressor, also should consider to use equipment station, otherwise not amused.
Must screw machine have equipment opportunity? What basis does this word have? Be known according to me, the screw machine of Howden did not consider equipment aircraft in Chinese sale (I have particular sale detailed account) , making clear me can not be to hold in the palm, I am offerring type to seek advice to one user.
I feel, do not have how old relation with what compressor, basically treat your use condition. If craft requirement is very strict, do not allow air feed to interrupt, must have equipment opportunity. If be common only,use an occasion, need not have machine is OK also. Just think one, who can make sure whose compressor does not give an issue? !
Hum, really such, what I feel upstairs to this says is reasonable!
The 4L-20/8 that two Chinese some factories of our unit produce pneumatics machine each other is reserve, operating mode is OK still! Every work every year 11 hours continuously everyday, it is half an year should change low-pressure asbestine is filled up (drive sb. to his death, heavy ah) .
Ah, upstairs, asbestine fills up those who had chosen, assure a few years to need not be changed.
The problem of equipment aircraft is to answer to be decided actually according to production really, if be successional mass production, or because equipment stops machine the immediate loss that cause is very big (be like vitreous furnace, steel-making furnace) , or indirect loss is huge (if order for goods is lost, time limit for a project delays a huge sum to compensate for) , or it is to predict demand will increase prospective dosage ceaselessly etc, need to consider to reserve certainly abundant quantity.
Our unit has 15 pneumatics opportunity at present, design ability is 65 thousand stere about / hour, predict user dosage will grow ceaselessly before a few years when extend, reason obligate about 9000 stere / of the hour reserve abundant quantity, through a few years the user is produced ceaselessly, dosage is at present highest when the peak actual a remnant be not worth 3000 stere / of the hour reserve abundant quantity, equipment maintains normally overhaul arrangement is very difficult, and project approving applies for to buy pneumatics machine to cannot be approved tardy come down, estimation batch when coming down, we reserve finally repeatedly make rich the quantity is done not have, if to the user production causes an effect, loss but too big.
So big with tolerance, run, leakage scarcely can be ignored avoid!
Want to inspect operating mode and be decided with what pneumatics machine, a lot of users use gas now is 24 hours uninterrupted, without the word of equipment aircraft, with respect to hard to bear.

Screw chance wants chance having equipment commonly, because piston machine is more familiar to the user, without giving thought to issue size can oneself are maintained, and screw aircraft is different, in case leader occurrence problem, him user cannot be solved, want to have equipment opportunity so.
Equipment chance should give very big cost, if the stage counts the compressor in the unit more, can consider to reserve or a few, if need to have only in all, you have even, that is not economical! Import compressor especially! So, still suggest to consider to buy a function to had been compared, need not equipment aircraft.
Equipment aircraft is unprepared machine, the key is to look to use a case actually of the user, whether serial production cannot stop, whether to have new development it is program, better to whether have profit, it is a kind of integrated choice, is not the compressor of what brand. The individual suggests: If the enterprise has certain dimensions, have better outstanding achievement, should be an entrance aircrew, a homebred aircrew, one has.
A lot of users ask the supplier has reserve machine, once his machine gives trouble, of requirement supplier reserve machine reach the designated position a few hours air feed.
Idea is good, can you be this likelihood? Although resemble a mobile telephone same, offer equipment opportunity freely, install do not want time?
With need not have reserve machine or the condition using gas that treats the person that use, it is 24 hours of movement, scale of production is big, the demand is high etc, still have the state of mind that is investor and actual strength.
My company great majority is use China some compressor machine of factory piston pneumatics, overall moving case is good. But still use reserve machine, be ready for any eventuality.
The word outside the problem: The about screw compressor professional book on the market is too little, use a field especially. Is for instance compressor in spin / chemical industry / generate electricity / balata / glass / pharmacy / does brew wait an industry a moment specific on what craft to use? Be badly in need of each grant instruction.
Our unit is 24 small air feed, have opportunity of pneumatics of 5 screw type at present, just use quite. Because do not have equipment aircraft, of equipment maintaining normally also is to look at commonly do for nothing. Once appear breakdown, we are miserable, of production should drive sheet, had wished 10 minutes to be about to do calm, with fight like maintenance.
Have feeling greatly, did not reserve machine, do not have an accident criterion already, have an accident to be produced by accident with respect to meeting loss of working time, do not drive give order form, only reparations.

Need not entrance machine have commonly machine? ? ? Fallacy. The choice of equipment aircraft, whether is the demand that should see a client be supplied to gas successive.
