        gas reciprocating compressor commonly used control methods are the following:
1
speed regulation, speed regulation by varying the compressor speed to adjust the amount of exhaust gas. Advantages of this regulation is smaller than the power consumption of gas continuously, at all levels, compressor pressure ratio unchanged, the compressor without a regulating mechanism of specialized; but it only widely used in driving machine for internal combustion engine compressor and turbine, if the driving machine for a motor, you need to configure inverter, due to the large power and high voltage frequency converter the price is expensive, and require a lot of maintenance and repair work, therefore, the method rarely used reciprocating compressor at present in the motor drive on. In addition, variable speed regulation may have adverse effects on the work of the compressor, such as valve flutter, components wear, vibration increase, inadequate lubrication and so on, but also limits the wide application of the method.
2, the clearance adjust the cavity
in the compressor cylinder, in addition to the fixed clearance volume, also have no certain cavity, when adjusting the access cylinder working chamber, the clearance volume increases, the volume coefficient decreases, the exhaust quantity to reduce, which is more than the working principle of gap cavity adjustment.
