Cooler compressor vibration test system, including compressor, vibrating sensor, exhaust pipe, air intake duct and vibration are surveyed
Control device is tried, vibration-testing control device is connected with compressor, it is characterised in that：Further include the evaporator being connected and condensation
One end of device, exhaust pipe and air intake duct is connected by vibration isolation hose with air-breathing nozzle, the exhaust pipe mouth of compressor respectively, exhaust pipe
It is connected with evaporator and condenser with the other end of air intake duct；It is respectively equipped with and shakes at the air-breathing nozzle and exhaust pipe mouth of compressor
Dynamic sensor.
Further, three directions of the x, y, z at the air-breathing nozzle and exhaust pipe mouth of compressor are each provided with vibration and pass
Sensor.
Further, the vibration isolation hose is the quick coupling that both ends carry nut living.
Further, the other end of the air intake duct and exhaust pipe is connected by four-way valve with evaporator and condenser.
Further, the vibrating sensor is acceleration transducer.
Compared with the prior art, the utility model is provided in compressor real work in vibration test system and is connected
Evaporator and condenser, can measure compressor in the case that actual loading Vibration Condition；And due in compressor suction duct
Mouth is designed with the quick hose joint for vibration isolation with exhaust pipe mouth, and thus prevent what is vibrated between compressor and pipe-line system
It transmits, avoids influence of the pipeline vibration to compressor, test result is the vibration of accurate compressor body, be can be directly used for pair
The evaluation of compressor body vibration or the input of pipeline vibration CAE finite element simulation load.
