Multi-stage pump for synthetic resin industryThe removal and installation procedures follow certain operating procedures in the synthetic resin industry to ensure the performance and service life of the pump.
Removal procedure for 1. multistage pump
1. Preliminary preparation: to ensure that the working environment is clean and tidy, prepare the necessary tools, such as wrenches, screwdrivers, hammers, etc. Close the inlet and outlet valves of the multi-stage pump, disconnect the power supply, and ensure that there is no pressure inside the pump body.
2. Remove the housing: Use a suitable tool, such as a wrench, to remove the housing of the pump.
3. Remove the bearing: according to the type and structure of the bearing, use special tools to remove the bearing.
4. Remove the seal: According to the type of seal, such as mechanical seal or packing seal, follow the corresponding steps to remove it.
5. Disassemble the impeller: Use a special tool, such as a puller, to remove the impeller from the shaft.
6. Check the internal parts: check the pump body, impeller, bearings, etc. for wear or damage, and make records.
Installation steps of 2. multistage pump
1. Preliminary preparation: ensure that all disassembled parts have been cleaned, check and confirm that all parts are intact. Prepare the tools and materials required for installation.
2. Installation foundation: Ensure that the foundation of the pump is flat and firm to ensure stable installation.
3. Install bearings and seals: Install bearings and seals correctly according to the manufacturer's instructions.
4. Install the impeller: Install the impeller on the shaft to ensure a tight fit between the impeller and the shaft.
5. Install the shell: Install the shell of the pump to the foundation to ensure a good seal between the shell and the pump body.
6. Connecting pipes: Connect the inlet and outlet pipes according to the flow direction to ensure that the connection between the pipe and the pump is well sealed.
7. Debugging and testing: Before turning on the power, check whether all connections are firm, and then perform a trial run to check whether the pump is running smoothly and whether there is leakage.
8. Post-maintenance: regular inspection and replacement of seals, bearings and other wearing parts, to maintain the good operation of the pump.
3. considerations
1. During the disassembly and installation process, ensure the correct position of all parts and the correct installation sequence.
2. Use appropriate tools and protective equipment to avoid injuries during operation.
3. Regularly check and maintain the multi-stage pump to ensure its normal operation and extend its service life.
The quality of the assembly directly affects the normal operation of the pump, and affects the service life and performance parameters of the pump. Therefore, special attention should be paid to the machining accuracy and surface roughness of the protection parts during the assembly process, to ensure that the impeller outlet flow channel and the guide vane inlet flow channel are neutral, and the relative position of the packing ring in the packing cavity is correct. After the assembly is completed, check whether the pump rotor rotates flexibly in the pump and whether the axial movement meets the specified requirements.
The removal and installation of multi-stage pumps in the synthetic resin industry requires professional knowledge and experience, and it is recommended that professionals operate them. Correct disassembly and installation can ensure the normal operation of the multi-stage pump and extend its service life.
