33、, close the cock of pressure gauge to prevent pressure gauge from being damaged due to instant start and sudden rising pressure. Start the motor after finishing the following proce dures. Open the cock of pressure gauge when the motor runs at normal rotary speed. Rising pressure value will be seen t

Note: The outlet valve can only be closed when the pump starts or stops, and if the actual work-ing point of pump is not the point specif ied in the con

35、tract, adjust it with valve.3. OperationThe pump must work within allowable scope, not the s-cope with low discharge. If it runs long-term within such sc-ope, machine load will increase greatly, making parts fail in standing. However, instant working within this scope is all-owable, for example, sta

If the pump is out of work for long time, close inlet valve, demount water pump, dry up the water on the parts, and then apply antirust

37、oil to processing surface and keep it well. Start the pump for about five minutes every month or three months to ensure the pump start at all time and avoid deposit producing in the pump or pump inlet.
