Check the inspection before starting the YHB shaft oil pump: http://
First, use the YHB shaft oil pump before starting inspection
1. When the pump is tested daily, the return valve should be fully open and the valve block valve should be in the closed position. After the test pump is completed, all valves are returned to the specified state.
2, the pump inlet valve must have a normally open, the outlet valve is in the closed position.
3. When an emergency or fire drill requires oil, open the valve in the position corresponding to the fire oil (foam) and the return valve is closed.
Second, YHB shaft oil pump start and stop pump operation steps
1 After starting the pump, check the running current of the motor and the operation of the oil pump. If there is any abnormality, stop the pump immediately.
2 After the pump is properly oiled, move the clutch handle of the vacuum suction device to the “minute†position.
3. Observe the pressure gauge at the outlet of the oil pump. When the gauge pointer reaches the rated working pressure and stabilizes, gradually open the outlet valve and try to make the pump work under the rated condition.
4, should always check the temperature of the pump and motor bearings, the maximum temperature can not exceed 75 degrees, check the operating current of the motor should be within the normal range.
5. After stopping the pump, all the valves are returned to the normal state according to the requirements of the valve opening and closing state diagram.
6. Open the bleed valve to reset the float assembly and prepare for the battle.
Third, YHB shaft oil pump maintenance and maintenance
1. Check and ensure that the power supply and circuit of the fire protection system are smooth and the electrical equipment is in good condition.
2. Once every shift, the coupling should be light and heavy, no abnormal noise and record.
