Abstract: The pressure pulsation generated by the compressor during operation in the refrigeration system will directly affect the noise and vibration of the machine under test, and in order to carry out a joint analysis between pressure pulsation and noise and vibration, it is necessary to monitor the pressure pulsation of the compressor pipeline. According to the needs of testing, we first select the capture card, sensor and other hardware of the test device and then design and develop the supporting test software, this device can be used as a reference for relevant R&D personnel, with certain engineering application value.

Key words: Compressor, Pressure pulsation, Test device
