Insufficient outlet pressure of liquid ring compressor
Thread Content
Loading yard oil vapor recovery device liquid ring compressor model 2BE1 152-7, manufacturer Ji Dinashi, problem: The outlet pressure is insufficient, adjust it up to 1.4bar through the outlet valve, and the inlet pressure alarm is 80kpa, which cannot be increased any more. Design pressure 2.2bar ； The frequency conversion motor speed is 1450, which is the maximum ； Inlet filter disassembly and inspection is normal ； The sealing liquid is gasoline, the flow rate is 4 liters/hour, which is the maximum ； The inhaled gas is the gas evaporated during the loading process of gasoline. The outlet is a washing tank, which is washed by gasoline and then enters the adsorption membrane. It has been disassembled and inspected, and the gap between the impeller and the disc side is normal at 0.25. The clearance with the shell is normal.
Check the working fluid temperature to see if the heat exchanger cooling water is scaled
Check whether there is any air leakage in the inlet pipe. The unit is overloaded.
The skid used for the oil and gas recovery device depends on the manufacturer.
