Air compressor, we know, be the machine that is terminal unit air feed is exported thereby after compressing air. Greatly small shop, spin, chemical fibber, cement, glass, steam deserves to wait for an industry to need to use air compressor, so how does the choose and buy suit him factory to use angry sky to enrage compressor? Above all what we should know we are bought is equipment of air compressor system, those who use is to compress air, type selecting 3 essential factor are very main: A, pressure: P is nodded with gas + conduit pressing
VSD (gearshift drive) compressor gearshift drive (Variable Speed Driver) , normally abbreviation is VSD, it is the mark that compresses air domain. The air that deploys VSD compresses functional enough self-correcting its traversal speed, reduce air demand with matching accurately in real time. The biggest side that always has cost considering compressor is the electric power that its consume, is not air compressor itself buy the price, this is in energy-saving respect especially important!
A lot of centrifugal when doing the market to publicize with compressor of the screw that do not have oil, say to obtain attestation of orgnaization of tripartite authority, yielding compression air oil content can achieve Class 0, can achieve do not have oil absolutely. It is not quite rigorous that this is stated. Manufacturer and user are to negotiate the numerical value under Class 1 to the definition of Class 0 of total oily content in ISO8573-1 2010, is not under 1 class is 0 class, not be not to have oil absolutely more.
prepares before starting 1. Examination machine circuitry is normal; Whether is examination oil level inside normal limits; 2. Water-cooling aircrew opens cooling water circulatory system, whether does test circulatory system move normally; 3. Add a few clean engine oil from the mouth that take energy of life, the hand moves turning (leather belt and straight couplet type) ; 4. Electrify, examination three-phase power supply is normal, have cold dry opportunity should start cold dry chance first; 5. Not be too short time (a week goes to two weeks) stop machine
In the electric energy that air compressor wastes, change truly become those who compress air to have efficiency to be less than 20% , additionally 80% above are changed into heat energy. If compressor of air of will much stage comprises air to compress a group of planes to undertake centralized controlling, this also is confirmed to be a kind of efficient energy-saving way. The sources of energy that national hair changes actually to apply uses up gross and intensity “ double accuse ” to act, be with energy-saving carry high-energy effect to promote economic transition to upgrade, of transition of green of the sources of energy
What pneumatics machine uses in our life is exceedingly frequent. Although pneumatics machine gave our life to bring very big convenient, but pneumatics machine needs often maintain. As we have learned, the try out life that the locomotive environment that improves pneumatics chance can prolong pneumatics machine. Fall how to make the locomotive environment that can improve pneumatics chance for everybody introduction below. How to make the locomotive environment that can improve pneumatics chance especially now is the summer, pneumatics machine maintains the number increases, ask each fittings need
1. leather belt (shaft coupling) corrective is like air compressor is to use belt-conveyor, criterion the degree of tightness of leather belt is spent should be 10~20 millimeter between, if air compressor is shaft coupling drive, the hand answers after installation is fine dish the balance when use electric machinery and lead plane and examining shaft coupling to turn is spent. Air compressor shaft coupling uses stretch shaft coupling basically, spend evenly when error is not big but oversight. 2. Leader gets lost school no less than to maintain in screw air compressor had demolished in the process advocate report
1 why cannot use pneumatics machine eduction directly compress gas? Air has condensability, classics air compressor is contractible to air itself bulk, the air after pressure increases makes compress air. From pneumatics machine vent of direct eduction compress air, have the following characteristic: Water is contained in ▊ air, in including air of water mist vapor, condensate, the air that contains certain amount vapor makes moist air, the air of not hydrous steam makes do air. The sky all round us
Air compressor is the facility with a kind of huge power consumption, its occupy China to generate electricity about with n 7% of gross, its form basically has type of piston, circumgyrate, blade type to wait. Screw compressor is a kind of circumgyrate type compressor, general application is in China each industry domain. Current, the screw of 160kW above reduces functional effect rank inferior, only the product of individual business can reach II level can effect, product of absolutely large number basically is in III class can effect level. Use this technology at present
