1. Installation precautions before use

1. The base of the pump needs to be leveled and fixed with concrete as the foundation.

2. After the water pump is installed in place, after all the pipelines are connected, you must recheck and adjust whether the water pump and the motor coupling are concentric. There must be a gap of about 3mm between the two couplings.

3. For the up-suction installation, if the suction pipe of the pump is not equipped with a siphon barrel, a bottom valve must be installed. The total length of the pipe should not exceed 6 meters and there should be no more than 1 elbow of 90 degrees. , The tightness of the pipeline must be ensured, and there should be no air leakage, otherwise it will affect the normal operation of the pump.

4. The outlet pipeline of Industrial Sump Pumps must be equipped with check valves and shut-off valves. If conditions permit, install a pressure gauge or flow meter with corresponding pressure inside the valve to control the flow and pressure of the pump. Never run the valve fully open and large flow for a long time, otherwise it will cause the motor to heat up and even burn.

5. The pump motor must be equipped with qualified electrical starting and protection devices to ensure the normal operation of the pump.

6. Add an appropriate amount of lubricating grease to the bearing box of the water pump. Note that the oil level is appropriate to 1/3 of the side oil sight glass, and must not exceed 1/2 of the oil sight glass.

7. Due to the unique power combination sealing method of the pump, cooling water must be connected to cool the shaft sleeve and oil seal to extend the service life of the sealing device (the pressure of the cooling water should not be too high, and it is better to flow out naturally).

2. Attention

1. Fill the pump cavity and inlet pipe with liquid first, and close the outlet valve.

2. Open the machine seal cooling water.

3. Check whether the rotation of the motor is correct.

4. Turn on the power and start the water pump.

5. Slowly open the outlet valve, and at the same time adjust the valve by observing the pressure gauge or flow meter and control the valve stem at a certain position to ensure that the pump runs within the normal parameter range (if the pressure gauge and flow meter are not installed, the motor can be measured The current value to control the running state of the pump).

6. During the operation of the pump, attention must be paid to the liquid level of the suction pool at all times, and it must not run without liquid, otherwise it will cause irreparable damage to the pump.

7. Before stopping the Sump Slurry Pump, please close the outlet valve. In winter, the liquid in the pump cavity must be drained to prevent freezing and cracking.

3. Precautions for maintenance

1. The state of the water pump must be checked every 500 hours of operation, check the concentric state of the coupling, and add an appropriate amount of lubricating grease.

2. The water pump must be routinely maintained and maintained every 1500-2000 hours of operation, and the running status of the wearing parts such as bearings and mechanical seals must be checked. If worn, they must be replaced in time.

3. In the process of repair and maintenance, try to use qualified original parts and operate by professional technicians to ensure the normal use of the pump and extend the service life of the pump. The water pump is the same as other operating equipment. The normal operation, maintenance and regular maintenance of the equipment directly determine the service life and use status of the equipment.
