 Pump installation

Blindly starting the motor is strictly prohibited. Only after confirming that the motor is turning correctly can the coupling pin be installed.

1. Remove the grease and dirt from the base and place it on the foundation.

2. Thread the anchor bolts into the foundation holes of the base, install nuts above and below the base holes of the anchor bolts, and place support rails or wedges (with a support height of 50mm) under the base to align the pump inlet and suction pipeline flanges.

3. Use a spirit level to roughly adjust the levelness of the pump in both vertical and horizontal directions on the inlet and outlet flanges.

4. For the first grouting, pay attention to ensuring that the anchor bolts are vertical and do not touch the equipment.

5. After the concrete is completely cured, tighten the upper and lower nuts of the base evenly, and then proceed with a second grouting.

6. Remove the coupling cover and check the gap between the couplings. There should be a certain gap between the couplings, usually 4 millimeters. Check if the pump shaft and motor shaft are concentric, and adjust them with a thin gasket. The difference between the outer circle of the coupling should not exceed 0.1 millimeters, and the maximum and minimum difference between the end face clearance should not exceed 0.3 millimeters.

7. The suction pipe diameter should be the same or slightly larger than the inlet diameter of the pump, which not only avoids cavitation of the pump but also prevents sedimentation of the slurry in the pipeline.

8. To minimize the deposition of slurry in the pipeline and vortex shell, an opening should be made below the parallel pipe section between the suction pipeline and each gate, and a discharge valve should be installed (the diameter of the valve depends on the density of the medium) for discharge after parking.

9. For the convenience of pump maintenance, an inlet valve should be installed with a diameter equal to the suction pipe diameter of the pump. Expansion joints should be installed between the suction port and suction pipe of the pump for easy disassembly and assembly.

10. The diameter of the discharge pipe should be the same or slightly larger than the outlet diameter of the pump.

11. The pipeline should have its own support and the weight of the pipeline should not be added to the pump to avoid crushing the pump.

12. When installing the pump, try to keep it below the liquid level as much as possible to achieve the best performance of the pump.

Use, maintenance, and upkeep of pumps

start

1. Check if the lubricating oil level is half of the oil level gauge. (Lubricating oil has been added before leaving the factory)

2. If it is a double end mechanical seal (water tank structure), clean water (or engine oil) should be injected into the water tank to the specified water level first, and then the water tank should be sealed to circulate as required.

3. After jogging the motor and confirming the correct direction of rotation, the coupling pin can be installed. Do not blindly start the motor to prevent the impeller from falling off.

4. Open the inlet pipeline valve, and after the water pump is fully filled with water (for machine sealed pumps, check whether the machine sealed water tank or external water injection is normal), connect the power supply, and gradually open the outlet pipeline valve when the pump reaches normal speed. It is strictly prohibited to start the pump after all pumps are turned on.

cease

Turn off the motor. If the pump has been out of service for a long time, drain the liquid inside the pump to avoid freezing the pump in winter. Maintenance and upkeep

1. Regularly replace with new oil, with a cycle of 2-3 months.

2. When sealing with packing, regularly check the leakage of the shaft seal water. If the leakage is severe, adjust the packing gland or replace the new packing in a timely manner, so that the external water leaks in a droplet shape.

3. When using double-sided mechanical seals, regularly check the water level and turbidity of the water tank, and add water or replace clean water in a timely manner.

4. If the pump is stopped for a long time in winter, the inlet valve should be closed, the pump should be started to idle for a few minutes, and residual slurry inside the pump should be discharged to prevent freezing and cracking of the pump body.
