V. START-up, OpERATION AND MAINTENANCE
Caution: It is prohibited to run without liquid, which will damage mechanical
seal and sliding bearing.
1. Do not start the pump until it has been filled with water or liquid fully.
· Fill water in pump in inverse pouring system.
Close the pump outlet valve, release air vent screw on the pump head, and open the
inlet valve slowly until stable water flows from the air vent screw.
Then fasten the screw.
· Fill water in pump when liquid level is lower than pump. Before installing,
pump and pipes must be filled with liquid fully and air vented.
2. Check the rotary direction
Switch on the power supply and view the rotary direction by viewing the
motor fan. From the motor end, pump shall run counter-clockwise.
3.Check before pump start-up
· Check whether the pump is fixed securely.
· Check whether pump is filled with water fully and check whether liquid
can flow freely.
· Check whether the voltage of power supply is stable.
· Check whether it turns correctly.
· To make sure all pipe lines are connected tightly and can supply water
normally.
· The valves in the inlet pipe line are completely opened.
· The outlet valve shall be opened slowly after the pump is started up.
· Check the operation pressure if pressure meter is installed.
· Check all the controls for normal operation. If the pump is controlled
by pressure switch, check and adjust the starting pressure and stopping pressure.
Check the full load current to make sure it not surpasses the max allowed
current.
4. Frequency of pump starts
· Pump should not be started too frequently. It is suggested pump shall
not be started more than 100 times per hour if the motor power is less or equal
to 4kW. When motor power is big than 4kW, pump shall not be started
more than 20 times in one hour.
· Suggestion: When pump running, flow should be controlled at the range
of 0.5-1.3 times of rated flow.
· There should be no noise when pump running. If there is something
wrong, stop pump and check it and repair.
