Piston Refrigeration Compressor Multi-unit Parallel System Design | Cold Storage Compressor Rack Control
Unbalanced load distribution causes 30% of parallel compressor rack abnormal wear, xiteliduo Refrigeration Compressors introduces multi-compressor parallel design parameters for cold storage projects. Piston refrigeration compressor parallel rack needs oil equalization pipeline. Oil level difference between units must be kept within ±8 mm during steady running. Semi-hermetic refrigeration compressor parallel system adopts suction header pressure control. The pressure fluctuation of shared suction manifold should be less than 0.04 MPa. Cold storage refrigeration compressor parallel rack shall stagger startup sequence. The time interval between unit startups is at least 60 seconds to avoid simultaneous high inrush current. Each compressor branch must install independent check valve. It prevents reverse gas flow and oil backflow into stopped compressor cylinder. 10 recommended hot search keywords: piston refrigeration compressor, semi-hermetic refrigeration compressor, cold storage refrigeration compressor, refrigeration compressor parallel rack, refrigeration compressor oil equalization, refrigeration compressor suction manifold, refrigeration compressor check valve, refrigeration compressor manufacturer, cold storage rack system design, refrigeration compressor supplier
FAQ
Q1: What percentage of parallel rack abnormal wear comes from uneven load distribution? A: 30% of abnormal wear in parallel compressor racks arises from unbalanced load. Q2: What oil level difference limit is required between parallel piston compressor units? A: Oil level deviation between parallel units should be within ±8 mm. Q3: What suction manifold pressure fluctuation limit for semi-hermetic parallel rack? A: Suction header pressure fluctuation should be controlled below 0.04 MPa. Q4: What time gap should be kept between startup of different parallel compressors? A: Leave at least 60 seconds between starting each unit. Q5: What component is required on each compressor suction branch of parallel rack? A: Independent check valve for each compressor branch. Q6: What risk exists without check valve on parallel compressor branch? A: Reverse gas and oil flow will enter the stopped compressor cylinder. Q7: What is the function of oil equalization line in multi-piston compressor rack? A: Balance lubricant level to prevent oil shortage in any single compressor.
