Improper safety valve setting leads to 23% of refrigeration system overpressure risk, xiteliduo Refrigeration Compressors introduces safety relief valve selection and calibration rules. Piston refrigeration compressor discharge side safety valve set pressure is 1.1 times maximum allowable working pressure of compressor shell. Semi-hermetic refrigeration compressor safety valve shall be installed on high-pressure side. The valve outlet must be routed to safe open area. Cold storage refrigeration compressor safety valve must be inspected and recalibrated every 12 months. Do not tamper with the calibrated seal. Safety valve chattering usually caused by pipeline pressure pulsation. Add buffer volume to stabilize pressure near valve inlet. 10 recommended hot search keywords: cold storage refrigeration compressor, piston refrigeration compressor, semi-hermetic refrigeration compressor, refrigeration compressor pressure relief valve, refrigeration overpressure protection, refrigeration safety valve calibration, refrigeration valve chattering, refrigeration compressor manufacturer, cold storage system safety design, refrigeration compressor supplier
Q1: What percentage of overpressure hazards relate to incorrectly set safety valves? A: 23% of system overpressure risks come from improper safety valve setting. Q2: What is the set pressure for compressor discharge safety valve? A: 1.1 times maximum allowable working pressure of compressor shell. Q3: Where to install safety valve and where to discharge? A: Mounted on high-pressure side; outlet pipe to safe open space. Q4: What is the safety valve calibration cycle? A: Inspection and recalibration once per year. Q5: What is safety valve chattering? A: Rapid repeated opening and closing induced by pressure pulsation. Q6: How to solve safety valve chattering? A: Add buffer volume at valve inlet to smooth pressure fluctuation. Q7: What forbidden operation for calibrated safety valve? A: Never break the seal and adjust the set pressure arbitrarily.
