Screw pneumatics machines and tools has volume small, noise low, efficiency is advanced advantage, got applied extensively in industrial production. We know the main technique parameter of screw pneumatics machine below. Article data offers reference only.
Discharge of 1. unit volume
In the discharge of actual air cubage of discharge point of level of air compressor unit, conversion the position that to the standard the total temperature of inspiratory position, total pressure reachs constituent. General, the unit volume discharge that screw pneumatics machine issues in formulary operating mode do not answer 95% under nominal cubage discharge.
2. aircrew power
Air compressor aircrew is finished compress air to output place to require total power input. Attention, total power input is not contained compositive the power that reduces aircrew to compress air aftertreatment equipment mediumly to use in air
3. aircrew compares power
In the regulation operating mode falls, the ratio of power of air compressor aircrew and unit volume discharge.
4. sky holds power
Compressor nose is in locomotive condition, and the aircrew power that unit volume discharge is zero hour. Popularly, when rated exhaust pressure is 0.7MPa, hold power and aircrew power for nothing than exceeding 35% ; When 0.8MPa, carry power upper limit not to exceed 29% for nothing. Screw pneumatics machine should make hold for nothing power the least through the design change, rated exhaust pressure is less than the screw pneumatics machine of 0.5MPa to should use oil pump to offer oil.
5. axis power
The power that place of compressor drive axis needs. It is equal to rate of exercise to benefit the internal organs to increase mechanical loss power, but the drive outside including (be like gear or belt-conveyor) losing power.
6. discharges baric force
The gas in standard discharge point is absolutely total pressure. Attention: 0.5% what if use pressure,be less than quiet pressure, OK and absolutely quiet pressure replaces absolutely total pressure
Screw pneumatics machine is below force of rated platoon atmospheric pressure and nominal cubage discharge, when environmental temperature 40 ℃ , cooling water takes water temperature 30 ℃ , of cooling water quantity and aircrew power than be more than 1.69 (L/min) / when KW, temperature of various nose exhaust should not exceed 110 ℃ , be more than 1.25MPa when rated exhaust pressure and when use synthesis lube, temperature of various nose exhaust allows to exceed 110 ℃ , but should not exceed 130 ℃ . Before oil gas is detached, compress airy lowest temperature to answer not under temperature of its pressure dew point.
The performance that the technical parameter of screw pneumatics machine can affect facility and use effect, machine of pneumatics of the screw outside dividing afore-mentioned parameter still has oil of temperature of noise DB(A) , exhaust, rotate speed, exhaust the content, quantity that use oil (L) , exit canal diameter, these parameter produce manufacturer every to differ somewhat, the user is choosing Shi Kegen to occupy his effective demand undertakes choosing.
What buy screw pneumatics machine, every equipment all should be in nameplate of marked place designation product, line out answers at least on nameplate following content:
A) product model;
B) produces the name of an article to say;
Discharge of C) nominal cubage, the unit is stere every minutes (M3/min) ;
Pressure of D) rated exhaust, the unit is million handkerchief (MPa) ;
E) axis power or drive electromotor power, the unit is kilowatt (KW) ;
F) over all dimension (long × wide × is tall) , the unit is millimeter (Mm) ;
G) is suttle, the unit is kilogram (Kg) ;
H) leaves factory number;
I) leaves factory days;
J) manufactory (generator) name and seat.
