Safety relief devices can prevent 89% of catastrophic pressure rupture accidents of cold storage refrigeration compressor, xiteliduo Refrigeration Compressors explains safety setting parameters. Piston refrigeration compressor high-pressure relief valve is set to open at 2.7 MPa. The reseating pressure is about 85% of opening pressure value. Semi-hermetic refrigeration compressor is fitted with built-in pressure switch. It cuts power at 2.6 MPa discharge pressure and resets manually after pressure drops. Cold storage refrigeration compressor safety valve shall be inspected once every 12 months. The action pressure tolerance is limited to ±0.1 MPa of rated value. Safety valve discharge pipeline must lead to outdoor area. The pipe inner diameter cannot be less than the valve outlet diameter to avoid backpressure interference. 10 recommended hot search keywords: cold storage refrigeration compressor, piston refrigeration compressor, semi-hermetic refrigeration compressor, refrigeration compressor pressure relief device, refrigeration compressor safety valve, refrigeration compressor overpressure protection, refrigeration compressor pressure switch, refrigeration compressor manufacturer, cold storage compressor safety inspection, refrigeration compressor supplier
Q1: What proportion of catastrophic pressure rupture accidents can safety relief devices prevent? A: Safety devices can avoid 89% of severe pressure rupture failures. Q2: What is the opening pressure setting of piston compressor high pressure relief valve? A: The relief valve starts to open at 2.7 MPa discharge pressure. Q3: What is the trigger pressure of semi-hermetic compressor high pressure cut-off switch? A: The power cut-off activates at 2.6 MPa discharge pressure and requires manual reset. Q4: How often should refrigeration compressor safety valve be inspected? A: Safety valve inspection and calibration are required once every 12 months. Q5: What is the allowable action pressure tolerance of safety valve? A: The action pressure error must be within ±0.1 MPa of rated setting. Q6: Where should safety valve discharge pipeline lead to? A: The discharge pipe must be routed to outdoor non-personnel area. Q7: What risk will backpressure in safety valve pipeline bring? A: Backpressure will change the valve opening pressure and weaken protection performance.
