基于阀片阻抗参数的空压机容积效率问题诊断

Problem diagnosis of the volumetric efficiency of air compressor based on valveplate impedance parameter

通过对活塞式空压机簧片阀阀片机械阻抗参数的测量,探讨了阀片的固有频率和振型与空压机容积效率、簧片阀结构之间的关系,提出了基于阀片阻抗参数的空压机容积效率故障诊断方法。

Through measuring mechanical impedance parameter of valve plate in piston type air compressor,The relation has been discussed which is between natural frequency,vibration mode of valve plate and air compressor′s volumetric efficiency,reed valve′s structure.The air compressor fault diagnosis method has been presented which is based on impedance parameter of valve plate.
