Within the cylinder for reciprocating motion of the piston moves to the right and left cavity of the piston in the cylinder pressure is below atmospheric pressure pa, suction valve opening, the outside air inhaled in cylinder, this process is called the compression process.When the output air pressure is higher than the pipe in cylinder pressure p, the exhaust valve opens.
Compressed air to the pipeline, this process is known as the exhaust process.The reciprocating movement of the piston is driven by motor slider-crank mechanism.The rotation of the crank movement into sliding - the reciprocating movement of the piston.
1. The thermal efficiency is high, because the works are now, than screw compressor piston compressor with high efficiency. The unit power consumption.
2. Strong adaptability, namely the exhaust range is wide, and is not affected by the influence of high and low pressure, can adapt to a wide range of pressure.In addition, the density of the gas effect on the performance of the compressor as well as speed type, so the same specifications of the compressor, used to compress it more easily when different media.
3. Apply pressure range, piston compressor from low pressure to ultra-high voltage, current industrial use of the maximum working pressure of 350 mpa, the pressure used in the laboratory is higher.
4. The material requirements is low, use common steel material, processing easier, also relatively low cost.Technology is relatively mature, production use of accumulated rich experience.
