Background technique
Low pressure fuel injector screw air compressor (0.6Mpa～1.25Mpa) for one-level compression has on the market replaced Piston Air Compressor completely.He is with good unfailing performance, vibrate little, noise is low, easy to operate, few easy workout part, high having obtained of operational efficiency use and favorable comment widely.Although one-level fuel injection helical lobe compressor is reliable and stable, reach the bottleneck that higher pressure is for he, so in mesohigh field or piston multistage compression realizes.
Existing piston machine multistage compression main frame uses the most extensive at mesohigh.He is that the method by improving temperature evaporation condensed water solves the problem that condensed water is separated out in a large number, so his delivery temperature is very high, the floor space that also has him to also have is large, noise is high, and vibration is large, and easily damaged parts is many, the shortcomings such as standby redundancy is many, and maintenance maintenance workload is large.Unit is with piston ring scuffing, and exhaust pressure and the air displacement obvious energy consumption that declines increases.
The middle pressure air compressor of two-stage screw rod series connection, have a fatal defect, because firsts and seconds is directly connected, what airborne moisture will be a large amount of in compression process separates out, separator is transpiring moisture timely, makes to cause emulsification after compressor oil and water mixing.Affected bearing and the gear lubrication of unit, unit shortens working life greatly.So such unit can not reach very high pressure, can not long-time continual operation.This type is eliminated abroad, only uses on the mobile compressor of mine engineering at home.
The medium voltage network of screw air compressor+cooling driers+screw rod pressure-increasing machine three machine series connection is external more novel middle pressure air compression systems at present.Cost is higher, and utilization amount is little.He has obtained very large improvement the shortcoming of appeal.But he is the units connected in series by three difference in functionalitys, so his floor space is still very large, each unit needs debugging coupling mutually.Each system control is relatively independent, higher to operation and maintenance difficulty.
To sum up, replace press in current piston with the advantage of fuel injection helical lobe compressor.Important core is exactly the problem whether two-stage fuel injection compression screw host can solve the problem of condensed water after one-level screw compression and main frame and rationally use the reliability of power (motor) transmission.
