Background
The compressor is a general machine for increasing the pressure of various gases, and is one of the most extensive products in the mechanical industry. The power plant is widely applied in many departments of national economy, and almost extends to many fields of industry, agriculture, transportation, medical treatment and health, national defense, scientific research and even people's life, and is indispensable power equipment particularly in the aspects of chemical industry, synthesis, coal, petroleum, building construction, ocean engineering and the like. The piston is a main part of a piston compressor and cooperates with the cylinder to form a compression volume. The quality of the piston design is strongly related to the performance of the compressor. The materials commonly used for processing the piston include cast aluminum alloy, gray cast iron, steel materials and the like.
The weight of the piston is designed to be light to reduce the reciprocating inertia force. The mass balance of each row of pistons of the compressors with more than two rows of pistons should be balanced as much as possible according to the principle of inertia force balance. In the design of the compressor piston, the low-pressure stage piston with a larger diameter generally adopts cast aluminum to reduce the mass, and the high-pressure stage piston has a mass close to that of the low-pressure stage piston to achieve the aim of balancing reciprocating inertia force, so that the compressor can stably and reliably operate. However, sometimes, because the cylinder diameter of the low-pressure stage is large and the piston mass is heavy, and the cylinder diameter of the high-pressure stage is small, the piston of the high-pressure stage is difficult to reach the mass of the piston of the low-pressure stage, so that the masses of the pistons of the rows are unbalanced, and the risk that the compressor cannot run stably exists.
