ABB PFSA140 3BSE006503R1 Suction Filter

PFSA140 3BSE006503R1 will be less than 2kg/m3 pressure gas ammonia through the system of gas ammonia main pipe into the inlet of the ammonia separator, separated from the liquid ammonia droplets, filtered out of the liquid ammonia droplets of gas ammonia flow through the system pipe into the compressor suction filters, and then through the filter in the filter to filter out gas ammonia entrained in the small debris (which suction filters are equipped with a thermometer to indicate the temperature of suction, and a shut-off valve connected to the suction pressure gauge to indicate the suction pressure). (The suction filter is equipped with a thermometer to indicate the suction temperature and a shut-off valve connected to a suction pressure gauge to indicate the suction pressure). Clean gas ammonia into the screw compressor for compression and pressurization (i.e., gas pressure from 0.3Mpa to 1.57MPa), the compressed gas to the exhaust port discharge.

PFSA140 3BSE006503R1 in the operation of the compressor, the oil pump to the compressor sprayed about 0.5 ~ 1% of the volume flow of lubricating oil, this part of the lubricant plays a cooling, sealing, lubrication role, at this time, the oil required to spray into the pressure must be greater than the compressor pressure of the gas ammonia, to ensure that the lubricating oil sprayed into the oil, where the oil and gas pressure difference detection point is an important parameter. These lubricating oil with the exhaust discharged into the oil separator, oil separation, oil separator is equipped with a safety valve, the role of the separator when the pressure is too large, then through the safety valve to empty. Thereafter the system is divided into gas process and oil process.

PFSA140 3BSE006503R1 from the gas process: after the oil separation of ammonia at a temperature of 60 ~ 70 ℃, 1.35 ~ 1.40MPa pressure into the condenser condensation into liquid ammonia, liquid ammonia into the liquid ammonia collector; from the oil process: in the oil separator separating the oil through the oil cooler, the cooled oil through the backstop valve (can only be single-direction circulation) into the Oil crude filter, filter out iron filings and other large particles of impurities to the injection oil pump inlet, by the oil pump pressure, and then by the oil fine filter further filtration back to the injection pipe into the compressor.
