Acquaer User Manual: Submersible Pump for Deep Well

1. Introduction

The Acquaer deep-well pump is a water lifting tool designed for direct connection between an electric motor and a water pump. It is suitable for drawing underground water from deep wells, rivers, reservoirs, and canals. This product is primarily used for farmland irrigation, providing drinking water for humans and animals in plateau mountain areas, and for water supply and discharge in cities, factories, railways, mines, and construction sites.

2. Use Condition

• Voltage fluctuating range: ±10% of rated values.
• Water temperature: Not higher than +95°F (+35°C).
• pH value of water: Between 6.5 and 8.5.
• Solid contents in water: Not larger than 0.25%, with a maximum diameter not over 0.09 inch (2.3 mm).

3. Installation and Notice

1. Ensure the inner diameter of the well casing conforms to the minimum diameter of the water pump. For new wells, use an air compressor or an old water pump to clean out sundries and soils. Verify water quality and temperature meet the use conditions. The water pump can only be installed if the water level in the well is up to standard.
2. After unpacking, check for any damage caused during transportation and storage, such as intact cables and plugs, and secure, leak-free joints. Contact professional personnel for repair or replacement if damage is found.
3. During installation, securely fix the electric pump and correctly install the earth leakage protective device or over-heat/over-current protective device. The electric pump must be reliably connected to the ground.
4. When the water pump reaches its installation depth, the motor and pump body may be packed separately. In case of separate packing, remove the filter screen and cable protection plate from the pump body (refer to Figure 1). Place the pump body onto the motor, ensuring the motor's spindle head smoothly slides into the coupling. Manually rotate the coupling to check for normal operation, then secure the connecting bolt (refer to Figure 2). Finally, reinstall the filter screen and cable protection plate (refer to Figure 3).

5. Cable Connection and Maintenance

Wire Extension Procedure

1. Step 3.8.1: Prepare the pump wire extension. Strip the cable by 2 to 3 inches using a wire stripper, then strip the insulation to reveal 1 inch of copper wire. Place a black heat shrink tube over the main cable, and small white heat shrink tubing over each individual wire.
2. Step 3.8.2: Insert the stripped ends of the extension wire into the butt connectors in the wire pigtail from the pump. Firmly crimp each splice with crimping pliers to hold the wires securely. Ensure correct matching when adding an extension cable.
3. Step 3.8.3: Slide the small heat shrink tubing over the butt connectors and wires. Use a heat gun or lighter to evenly heat the tubing on all sides, shrinking it over the wires. The tubing contains adhesive that makes the joint waterproof.
4. Step 3.8.4: Wind rubber splicing tape over the butt splice connections of the three strands of wire.
5. Step 3.8.5: Wrap the three wires together with hot melt adhesive, ensuring it is thicker at both ends.
6. Step 3.8.6: Slide the black heat shrink tube over the connection and evenly heat it on all sides with a heat gun or lighter. Ensure the tube heats sufficiently for the adhesive to squeeze out slightly from the ends.
7. Step 3.8.7: Wind waterproof electrical tape over the shrink tubing and wire.
8. Step 3.8.8: Immerse the junction of the cable into water for 12 hours. Test the insulation resistance of the cable using a 500V megohmmeter. The cold insulation resistance should be not less than 50 MΩ.

Delivery Pipe Connection

Step 3.9: The delivery pipe should match the water outlet specification. For soft delivery pipes, use iron wire or clamps for connection. For steel delivery pipes, use screwed joints for a reliable connection. Threading ropes should be used on the handle for lifting the pump.

Pre-Use Testing

Step 3.5: Before use, thoroughly test the insulation resistance of the electronic pump's stator winding (including the outgoing cable) to the pump casing using a 500V megohmmeter. The cold insulation resistance should be not less than 100 MΩ.

Trial Operation

Step 3.6: Connect the electric pump to the power source for trial operation before submerging it in water. The trial should not exceed 3 seconds. For single-phase pumps, connect cable lines according to the wiring diagram on the electric machine or control cabinet, strictly matching colors. Incorrect wiring can cause abnormal operation or damage. Three-phase pumps can be connected without differentiating cable colors.

Power Line Extension

Step 3.7: A power line can be extended for distant power supply. Select proper cable lines according to the table to avoid issues caused by excessively thin cables.

Cable Line Selection Table

Note: Choose the required cable cross-sectional area based on the pump's power and the external cable length to ensure normal motor operation.

Please ensure correct matching when adding an extension cable. Always cut off the power supply before wiring to avoid electric shock and accidents. For any questions, consult an electrician or contact Acquaer customer service.

6. Failure Reasons and Troubleshooting

7. Safety and General Notices

WARNING:

• Reliable grounding must be conducted before using water pumps. The earth leakage protective device and overload/over-current protective device must be installed.
• The electric pump is not allowed for dry running.
• When the pump is in operation, people and animals must not touch the water near the pump.
• To prevent electrical shock, the power source must be shut off during maintenance and cleaning.

General Usage Notes

• Tied ropes for hoisting the electric pump must be firm and durable. Cable lines should not be stretched but remain in a natural loose state.
• Cables are not allowed for impact, crushing, or use as lifting ropes. Do not pull cables randomly during operation to avoid electric shock from cable damage.
• The electric pump should be no deeper than 262 ft (80 m) in the water, but should be at least 10 ft (3 m) above the bottom. The pump shall not be sunk into soils. Prevent sundries from blocking nets or impellers, as this leads to abnormal operation. Check the water level during operation to avoid exposed or dry works, which can burn the electrical machine and other parts.
• Washing, swimming, or the presence of animals are not allowed within working regions during pump operation. A safety warning label indicating "electric shock risk, no entry" should be posted.
• The oil-filled electrical machine is pre-filled with appropriate food machine oil. Users are not allowed to fill any water or oil into the electrical machine, except for maintenance.
• If the oil-filled electrical machine leaks oil due to damage or breakdown, and it is used in environments like planting, cultivation, drinking water sources, or food transportation/processing, the leaked oil may damage plants, cultured animals, or pollute water/food. Users must evaluate the use environment and consequences before selecting the product. If oil leakage occurs, stop using the pump and address it properly.
• Always cut off the power source when adjusting the pump's position or contacting it to prevent accidents. Do not lift the electric pump out of the water surface after shutting down the power source to ensure safety.
• The electric pump is a specialized technology-based product. Unqualified repairmen must not conduct random disassembly. Sealing and insulation testing must be performed after reassembly.
• Maintenance should be conducted on electric pumps after 3,000 hours of normal operation. Easily damaged parts like mechanical seals, bearings, and impellers must be replaced. An air pressure test (0.4 MPa) must be conducted on motor and oil chambers after reassembly or mechanical seal replacement, with no leakage permitted within five minutes.
• For long-term non-use, the pump should not be left submerged in water. Instead, run it in clear water for several minutes to clean out mud. Apply anti-rust oil to the pump and store it in a dry, ventilated place. Pumps used for extended periods may require repainting or anti-rust oil treatment based on their surface corrosion status.
