Refrigeration Compressor Pressure Relief Valve Setting and Inspection | Overpressure Safety Protection
Improper pressure relief valve setting or failure causes 32% of overpressure safety hazard, xiteliduo Refrigeration Compressors explains safety valve specification. Piston refrigeration compressor high-side pressure relief valve set pressure is 1.1 times maximum allowable working pressure of system. Semi-hermetic refrigeration compressor built-in pressure relief device protects compressor shell from overpressure damage. Cold storage refrigeration compressor safety relief valve outlet must be vented to safe zone; never block or cap valve outlet. Pressure relief valve needs annual calibration; once opened by overpressure, it must be inspected or replaced immediately. 10 recommended hot search keywords: cold storage refrigeration compressor, piston refrigeration compressor, semi-hermetic refrigeration compressor, refrigeration pressure relief valve, refrigeration overpressure protection, refrigeration safety valve calibration, refrigeration maximum working pressure, refrigeration compressor manufacturer, cold storage refrigeration safety design, refrigeration compressor supplier
FAQ
Q1: What percentage of overpressure safety risks are caused by incorrectly set or failed pressure relief valve? A: 32% of overpressure hazards originate from misconfigured or failed pressure relief valve. Q2: What is the setting principle of high-side relief valve? A: 1.1 times of system maximum allowable working pressure. Q3: Where shall the safety valve discharge gas be vented? A: To a safe area; outlet must not be blocked or sealed. Q4: What inspection requirement for pressure relief valve? A: Annual calibration. Q5: What action is required after safety valve trips open? A: Inspect or replace the valve right away. Q6: Can we adjust the relief pressure arbitrarily on site? A: No, calibration must be done by certified professional institution. Q7: What risk if safety valve outlet is blocked? A: Pressure cannot release and may cause pipeline or vessel rupture.
