API 681 liquid ring compressor
API 681 liquid ring compressor system is fully assembled with all interconnecting wires and piping. The system is mounted on a common steel base and fully tested and painted before shipment. They include oil seals to provide a deeper vacuum than water or glycol sealing systems. The system consists of a single compound liquid ring compressor with mechanical seal and the following system components:
1. Pipette flexible connector
2. Suction isolation valve
3. Check valve of suction line
4. Adjustable vacuum control switch
5. Oil / water heat exchanger
6. Oil thermometer, valve and composite pressure gauge
7. Cooling water solenoid valve, filter and flow control valve can sense oil temperature and thermometer
8. Steel exhaust separator
9. Discharge oil mist eliminator through overflow valve and oil return pipeline
10. Drive motor tefc
11. Motor control center with electromagnetic motor starter, HOA switch and fusible circuit switch
