To ensure safe and efficient operation of the water pump, follow these detailed instructions carefully:
1. The pump should be mounted on a sturdy iron frame or wooden base that is at least 10mm larger than the motor's feet to ensure stability. Always connect the motor to a reliable grounding wire to prevent electric shocks and ensure safety.
2. Before starting the pump, inspect the motor for any signs of moisture, check the electrical circuit for damage, and make sure all mechanical components are properly aligned and not loose or jammed. If any issues are found, address them before proceeding.
3. Use a hose of the correct diameter for the pump. One end of the suction pipe should be connected to the bottom valve, while the other end connects to the pump’s inlet. Then, fill the pump with water through the outlet. Open the vent plug to release any trapped air, then tighten it once all air has been expelled.
4. The power cable should have a cross-sectional area of at least 4 square millimeters. Connect it to the main power line using a 10A single-pole switch. Never directly plug in a lamp or other devices into the pump’s wiring. Ensure all connections are secure and avoid wrapping exposed wires to prevent electric shock hazards.
5. After turning on the power, start the motor within 3 seconds. If it fails to start, immediately turn off the power and check the electrical system for faults.
6. When operating under low voltage or low lift conditions, monitor the motor temperature closely. If the pump becomes hot, the power will automatically shut off for safety. Once the motor cools down, it will restart automatically.
7. The pump uses a skeleton oil seal. Over time, this seal may wear out, especially if the pump runs dry. Replace the seal promptly if the pump is not submerged in water for an extended period.
8. Install protective covers for the motor and avoid exposing it to direct sunlight or rain. If the pump is not in use for a long time, drain all the water from the pump and apply a thin layer of oil or grease to the exterior to prevent rust and corrosion.
**Common Troubleshooting Tips:**
1. **Pump Does Not Start:** If the mechanical parts are stuck, adjust the alignment or clear any obstructions. If the issue is electrical, check the wiring and repair as needed.
2. **No Water Discharge:** Check for leaks in the suction pipe and reseal any faulty joints. If air is trapped, open the vent plug to release it. Ensure the pump is fully filled with water. If the shaft seal is damaged, replace it immediately.
3. **Low Flow Rate:** If the head pressure is too high, adjust the pump height. Clear any blockages in the bottom valve or impeller. Shorten the pipeline or reduce bends if the system is too long or has excessive curvature.
4. **Motor Overheating:** If the power cable is too short or too thin, replace it with a thicker one. Reduce the pump’s operating time if the head is too low. Adjust mechanical clearances to eliminate friction.
By following these guidelines, you can ensure the longevity and proper performance of your water pump. Always prioritize safety and regular maintenance to avoid potential failures.
