| Summary: | Two-stage reciprocating small oil-free air compressors have been widely used in various fields due to their high exhaust pressure and low power consumption, but the vibration and noise problems seriously affect the comfort of use. In order to improve the compressor vibration, the theory of dynamic balancing of a two-stage reciprocating air compressor was developed and a virtual prototype simulation was carried out using Adams software to establish an objective function to optimize the balance block counterweight of its crankshaft-piston system. Subsequently, in view of the close connection between the motor and thel compressor structure, the theoretical study and analysis of the dynamic balance of the crankshaft piston system and the motor rotor as a whole was carried out, and the dynamic balance scheme was further improved. Based on the above dynamic balance theory, vibration and noise tests are carried out and the noise are all reduced to a certain extent, verifying the reasonableness of the dynamic balance theory of the two-stage reciprocating small air compressor. |
