Screw the adjusting screw a little upwards, increase the spring force, and then run for another half an hour. Observe the pressure range of the gas tank. If the required pressure is not reached, continue to adjust until the pressure of the gas tank reaches double the rated value. Leakage through the gaps at both ends of the vane, where leakage from the lateral side of the compression side will result in a decrease in the suction gas, which directly affects the volumetric efficiency; the inner diameter portion of the rotor (which is a high pressure inside the casing) leaks to both sides of the compression and suction. Leakage to the compression side increases the compression work machine loss, while leakage to the suction side reduces the volumetric efficiency: the leakage on both sides of the slide has the same effect; the leakage of the end face of the slide is also the compression lateral direction. Leakage on the suction side reduces volumetric efficiency. In order to reduce the impact of leakage on volumetric efficiency and mechanical efficiency, each rotary compressor manufacturer adopts precision machining, precision assembly and matching size matching technology. In order to obtain the best fit gap value, in order to form a strong oil film, to ensure sealing, reduce leakage and reduce wear. Since the two-cylinder compressor improves the machining accuracy of the parts and reduces the matching clearance, it is easy to form a strong oil film between the sliding surfaces, so that after the accelerated life and various reliability tests, the wear of each sliding surface is also very small. The so-called compression efficiency refers to the ratio of the theoretical adiabatic compression work to the actual compression power: the theoretical adiabatic compression work is actually compressed by the rotary compressor due to suction loss, the pressure drop of the exhaust valve, the gas leakage between the piston cylinders, The piston end face, the slide groove leaking to the compression side, and the overheating of the cylinder wall will increase the work required for actual compression.
