How to operate? 1. Before starting the pump, open the gate valve and pump exhaust valve plug, close the outlet gate valve, fill the pump chamber with water, so that the pump can start normally.
2, start the motor, from the motor end, check whether the steering is in line with the correct direction. Operation of pump 1. After the pump starts, gradually open the outlet gate valve and adjust it to the required working condition.
2. During the operation of the pump, the flow at the point of operation condition should not be greater than the flow at the large flow point given in the performance parameter table, and the current of the motor should not exceed the rated current during operation.
3. Stop sequence: close the interline - motor - pressure gauge on the outlet pipe.
Pump maintenance: 1. We should often check whether the pump is stable during operation, whether there is mechanical seal wear and leakage, and timely replace the seals to prevent pressure water from entering the motor.
2, often check the temperature change of the motor housing, its highest temperature should not exceed 85 degrees, such as the temperature is found to be too high, should immediately stop the check.
3. When the pump is out of use for a long time, the water should be drained, the embroidery scale should be removed, and the antirust grease should be coated for the next use.
