Product details

Product features of PW centrifugal sewage pump:

Installation of PW centrifugal sewage pump:

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

2) Use a spirit level to check the levelness of the base, and allow for leveling with a wedge iron.

3) Pour cement into the base and anchor bolt holes.

4) After the cement dries up, check whether the base and anchor bolts are loose, tighten the nuts if they are suitable, and recheck the level.

5) Clean the support plane of the base and the foot plane of the water pump and motor, and then install the pump and motor onto the base.

6) Check if the level is consistent with the center of the motor. If not, adjust it with thin iron plates to make it concentric (no more than 3 thin iron plates), and leave a 2-3mm gap between the couplings.

Assembly and disassembly of PW centrifugal sewage pump:

First check for any defects that may affect the assembly of each component, then clean them thoroughly before proceeding with the assembly.

1. Prepare paper pads, plugs, and pipe plugs and install them onto the corresponding components.

2. Install the sealing ring, shaft seal box, oil gauge and oil hole cover, and felt stock into the pump cover, bearing body, bearing box, and bearing cover respectively. 3. First, install the bearings into both ends of the shaft, then install them together into the bearing box, and finally install the bearing cover.

4. Install the bearing body, bearing (4PW without) oil seal ring and washer, impeller, washer and impeller nut in sequence and tighten them, then install the pump body and pump cover. Disassembly and assembly must be done in reverse order.

Precautions for PW centrifugal sewage pump:

1) The inlet and outlet water pipes of the pump should be supported, and the pump body should not be used as a support:

2) The outlet water pipeline should be equipped with gate valves;

A general trash rack should be installed at the inlet of the pump suction pipeline to prevent larger stones and other objects from being sucked into the pump and damaging the blades.

PW centrifugal sewage pump starts, stops, and runs:

A、 start

1) Check if the bearing box has been filled with oil and if the oil level is within the normal range.

2) Check if the rotation direction of the motor is consistent with the rotation direction of the pump.

3) Close the discharge gate valve and pressure gauge plug, and at the same time, pour water into the suction pipe of the pump through the screw hole on the upper part of the pump body.

4) Start the motor and open the pressure gauge plug.

5) When the water pump reaches normal speed and the pressure gauge displays the corresponding pressure, open the vacuum gauge plug and gradually open the gate valve on the drainage pipeline until needed.

B、 stop

1) First, slowly close the gate valve of the water outlet pipeline, and then cut off the power supply.

2) In case of freezing season, after stopping the machine, open the square screw plug at the bottom of the pump body and drain the stored water to prevent freezing and cracking.

3) If not used for a long time, each component should be disassembled and cleaned, and rust proof oil should be applied to the sliding surface for proper storage.

C、 operate

1) During the operation of the pump, it is necessary to pay attention to the heating condition of the instruments and bearings, the leakage of the packing, and whether the vibration and noise of the pump are normal. If any abnormalities are found, they should be dealt with in a timely manner.

2) The maximum temperature of the bearing shall not exceed 75 ℃.

3) The bearing oil should be maintained at the normal oil level line, and should not be too high or too low. If it is too low, it should be refilled in a timely manner.

4) When the clearance between the sealing ring and the impeller exceeds the following specified value, a new sealing ring should be replaced.

When the diameter of the suction port is ≤ 100mm and the total clearance in the diameter direction is ≥ 1.5mm

When the diameter of the suction port is greater than 100mm and the total distance in the diameter direction is ≥ 2mm
