Check valve H41H-10P (FRD. WJA9. 047A Turbine Fire-resistant Oil Station Main Oil Pump Operation Guide)

Product Introduction

Key Operation & Maintenance Requirements (for FRD. WJA9. 047A Main Oil Pump)

• Ensure Stable Oil Suction: The filter screen at the oil suction port must not be clogged. The differential pressure gauge should be checked weekly; if the differential pressure exceeds 0. 3MPa, the filter screen must be replaced immediately. Otherwise, insufficient oil suction will lead to pressure fluctuations, and the FRD. WJA9. 047A main oil pump is also prone to cavitation, affecting its service life and operation stability.
• Proper Pressure Adjustment: The overflow valve at the pump outlet should be adjusted correctly. The set pressure should be 0. 5MPa higher than the system working pressure; for example, if the system requires 14MPa, the overflow valve should be set to 14. 5MPa. This ensures pressure relief when the system pressure is too high, preventing overpressure damage. At the same time, a pressure compensator should be installed to automatically adjust the pump's displacement when the oil flow changes, maintaining stable system pressure and avoiding fluctuations.
