Fully open inlet valve, close the cock of pressure gauge to prev

Open the cock of pressure gauge when the motor runs at normal rotary speed. Rising pressure value will be seen t-hrough pressure gauge and then open outle

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 contract, adjust it with valve.3. OperationTh

35、e 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, starting the machine.4. StopClose the cock of

36、 pressure gauge and outlet gate valve and open inlet valve. Ensure that machine set stops mildly when you stop the motor. 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 oil to processing surface and keep it well

37、. 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. Compl-etely exhaust liquid in the pump if it is out of use for long time and at low ambient temperature.123456278 910; 111213,14/p>
