The replacement of the water seal of a small fully automatic booster pump is a relatively simple but meticulous process. The following are the general steps for replacing the water seal for your reference: 1. Preparation work
1. Tool preparation: Prepare necessary tools such as adjustable wrenches, socket wrenches, Phillips screwdrivers, sandpaper, clean cotton cloth, lubricating grease, etc.
2. Power outage and drainage: Ensure that the booster pump is powered off, close the inlet valve, and drain the water from the pump body to reduce water splashing and safety hazards during the replacement process.
3. Confirm model: Before purchasing a new water seal, it is necessary to confirm the model of the booster pump and the specific specifications of the water seal to ensure that the purchased water seal matches the pump body. 2、 Dismantling process
1. Dismantling the outer cover: Use appropriate tools to dismantle the outer cover of the booster pump, and pay attention to recording or marking the positions of each component for subsequent installation.
2. Disassemble the pump body: Continue disassembling the relevant components inside the pump body, such as impellers, shaft sleeves, etc., until they can come into contact with the water seal. During the disassembly process, be careful not to damage other components.
3. Remove the old water seal: Use a special tool or gently tap the edge of the water seal to loosen it and remove it. If the water seal is tightly combined with the shaft sleeve or pump body, the contact surface can be lightly sanded with sandpaper, but excessive damage should be avoided. 3、 Install a new water seal
1. Cleaning the pump body: Before installing a new water seal, thoroughly clean the inside of the pump body, remove dust and debris, and ensure a clean installation environment.
2. Install new water seal: Install the new water seal onto the pump body in the correct direction, paying attention to the appropriate clearance between the water seal and the shaft sleeve or pump body, and not too tight or too loose. During installation, gently tap the water seal to evenly distribute it and ensure proper installation.
3. Apply lubricating grease: Apply a layer of clean lubricating grease on the sealing surface of the dynamic and static rings to reduce friction and wear. 4、 Assembly and Testing
1. Assemble the pump body: reassemble the pump body in the reverse order of disassembly, paying attention to the installation position and tightening torque of each component to meet the requirements.
2. Test run: After assembly is completed, connect the power supply and inlet/outlet water pipes, open the inlet valve and power on for testing. Observe the operation of the booster pump and check for any abnormal conditions such as water leakage or abnormal noise. 5、 Precautions
1. Safe operation: During the entire replacement process, ensure that the power has been cut off and take appropriate safety measures to prevent electric shock or other safety accidents.
2. Careful inspection: During the disassembly and installation process, carefully inspect the wear and damage of each component, and replace damaged parts in a timely manner to ensure the normal operation of the booster pump.
3. Professional maintenance: If you are not familiar with the structure and maintenance of booster pumps or do not have relevant experience, it is recommended to seek the help of professional personnel to ensure the quality and safety of maintenance.
By following the above steps, you can complete the replacement of the water seal for the small fully automatic booster pump. If you encounter any problems or difficulties during the replacement process, please consult professionals in a timely manner for assistance.
