Simulated liquid hammer test bench for four-way directional valve
Product test conditions and processes are automatically controlled by PLC system + high-precision sensors and measuring instruments, and real-time visual monitoring and measurement are realized through computer (touch screen) and data acquisition system. The test bench has complete test data acquisition and processing functions, including automatic recording of data and curve, automatic generation of test report, local storage of data, interactive sending, saving and receiving of data to server database and MEMS system, and can realize remote communication and diagnosis;
The test bench tests the performance of the four-way directional valve under periodic liquid hammer by creating the test conditions for liquid hammer of the four-way directional valve.
1. The refrigerant accumulation in the compressor for each refrigeration / heating cycle is greater than that of the compressor under normal conditions; 2. Collect and print the corresponding curve of refrigerant accumulation and time in the test compressor.
3. Collect and print reports of condensation pressure, evaporation pressure, condensation temperature and evaporation temperature
4. It has the function of counting the number of test cycles, and the minimum number of cycles is 500.
