Synthetic rubber industry multistage pumpThe removal and installation steps are important to ensure the normal operation and maintenance of the equipment. The following are the detailed removal and installation steps.

Removal procedure for 1. multistage pump

1. Close the inlet and outlet valves of the multi-stage pump and disconnect the power supply to ensure that the pump stops running completely.

2. Remove the fixing bolts between the pump body and the bracket, and remove the pump body from the bracket.

3. Remove the bearing gland and take out the bearing and the packing ring in the bearing.

4. Remove the connecting screws of each section of pump cover and pump body, and take out the pump rotors one by one. Pay attention to the order of the rotors so that they can be installed in the original order.

5. Remove the mechanical seal gland of each section and take out the mechanical seal parts.

6. Inspect the parts for wear or damage and clean all parts of the residue.

Installation steps of 2. multistage pump

1. Ensure that the installation foundation is stable and smooth, and provide a stable working environment for the installation of multi-stage pumps.

2. Install the pump body, bearing gland and other components in the reverse order of disassembly. Pay attention to the bearing clearance and the installation accuracy of the mechanical seal.

3. Put each section of the rotor back into the pump in order to ensure that the keyway of the rotor is closely matched with the driving key.

4. Install the pump cover and ensure that the connections are well sealed and free of leakage.

5. Connect the inlet and outlet pipes, and ensure that the pipe connection is firm and not loose.

6. Install the motor drive device to ensure that the transmission belt or coupling between the motor and the multi-stage pump is accurately matched.

7. Connect the power supply, check whether the motor rotation direction is correct, and carry out no-load test operation to ensure the normal operation of the pump.

8. After normal operation, check whether the connection of each part is tight and whether there is any abnormal sound or vibration. If there is any abnormality, stop the machine immediately for inspection and treatment.

3. FAQ

1. The multi-stage pump is loud: it may be caused by the wear of the impeller or the damage of the bearing, which requires inspection and maintenance.

2. Multi-stage pump water is not smooth: may be the impeller blockage or pump body inlet blockage caused by the need for cleaning and maintenance.

3. Water leakage of multi-stage pump: It may be caused by the failure of the sealing ring or the poor sealing between the impeller and the pump body. The installation position of the sealing ring and the impeller needs to be replaced or adjusted.

4. considerations

1. During disassembly and installation, handle with care to avoid damage to parts.

2. When disassembling and installing, pay attention to keeping it clean to avoid impurities entering the pump and affecting the operation effect.

3. After the installation is completed, a trial operation inspection should be carried out to ensure that the multi-stage pump runs smoothly without abnormal sound or vibration.

4. Regularly inspect and maintain the multi-stage pump to ensure its normal operation and extend its service life.

Follow the above steps to ensure that the removal and installation of the multistage pump is completed smoothly. Correct operation and maintenance can not only ensure the normal operation of the equipment, but also effectively improve the service life of the equipment.
