The installation process of a household self-priming pump is relatively simple, but some details need to be paid attention to to ensure the normal operation and long-term use of the pump. The following are the detailed steps for installing a household self-priming pump: 1. Preparation before installation
1. Check the pump body and accessories: Ensure that the household self-priming pump and its accessories (such as bottom valves, filters, pipelines, etc.) are intact and meet installation requirements.
2. Determine installation location: Choose a location with good ventilation and easy maintenance to install a household self-priming pump. At the same time, ensure that the installation position is stable and avoid the pump body shaking or shifting.
3. Prepare tools and materials: Prepare the necessary tools (such as wrenches, screwdrivers, etc.) and materials (such as pipes, joints, sealants, etc.) according to installation needs. 2、 Installation steps
1. Install bottom valve (if required): - If the liquid level is lower than the pump, a bottom valve needs to be installed at the suction port at the bottom of the water tank to ensure that the pump can properly pump low-level liquid- When installing the bottom valve, make sure that it is completely immersed in the suction body and cannot be exposed to the water surface.
2. Install a filter screen: Install a filter screen at the suction port of the inlet pipe of the household self-priming pump to prevent sand particles or other impurities from being sucked into the pump body, causing blockage or damage.
3. Connecting pipes: Use pipes that match the diameter of the household self-priming pump for connection. The pipeline joints should be sealed with raw tape or other sealing materials to prevent water leakage- The inlet of the imported pipeline should be about 0.3 meters away from the bottom of the pool to avoid inhaling particles at the bottom.
4. Electrical connection: Connect the cable of the household self-priming pump to the power supply, ensuring a stable voltage and a range of use between+5% and 12% of the rated voltage- Install leakage protection measures and ensure proper grounding protection for the ground wire to prevent electric shock accidents.
5. Water filling and exhaust: Before the first operation, it is necessary to open the inlet bolt of the self-priming pump and fill the pump body with liquid to eliminate the air inside the pump- After filling with liquid, tighten the bolts and then turn on the power for trial operation. 3、 Debugging and Running
1. Close the outlet valve: - Before connecting the power, first close the outlet valve of the water pump.
2. Start the pump: - After connecting the power, wait for about 1-2 minutes to allow the pump to fully absorb water and discharge air- Then open the outlet valve, and the water pump can enter the working state normally.
3. Check the operation: - Observe the operation of the household self-priming pump and check for water leakage, abnormal noise, or other abnormal conditions- If any abnormalities are found, the machine should be stopped immediately for inspection and troubleshooting. 4、 Post maintenance
1. Regular cleaning: Regularly clean impurities on the filter screen and bottom valve to maintain the cleanliness and smoothness of the pump body.
2. Check electrical connections: Regularly check whether the electrical connections are firm and reliable, and repair them promptly if they are loose or damaged.
3. Antifreeze measures: In cold seasons or outdoor environments with temperatures below 0 ° C, antifreeze measures should be taken, such as draining accumulated water from the pump body.
4. Long term disuse treatment: If the self-priming pump for household use is not used for a long time, the accumulated water in the pump body should be cleaned up and stored properly to prevent rust or damage.
By following the detailed steps above, the correct installation and normal operation of household self-priming pumps can be ensured. If you have any questions or difficulties during the installation process, it is recommended to consult professionals or relevant manufacturers for guidance.
