The high-lift deep well pump has the advantages of simple structure, convenient maintenance, small size, light weight, high efficiency, energy saving, long life, etc., but if how to troubleshoot during use, then let's learn about the installation and troubleshooting of the high-lift deep well pump!

　　high lift deep well pumpPreparation before installation:

1. Clean up the space.

2. Prepare all required equipment, tools and other items.

3. After unpacking, check whether the pump and motor enterprises are damaged, and check whether the random accessory information is complete according to the packing list.

4. Whether the delivery date of the pump should be checked before installation. If it is placed for a long time, the motor shaft and the pump shaft should be coiled to make it rotate flexibly.

5. Clean and wipe the pump installation interface, if there are defects affecting the pump installation should be corrected.

　　high lift deep well pumpInstallation and adjustment

1. Vertical installation of motor and water pump.

2. Set the plane key and spline to the motor shaft.

3. Install the pump on the motor, and tighten the fixing bolts diagonally

4. Rotate the pump shaft, check the assembly condition, rotate flexibly, and no partial grinding

5. Connect the cable and the motor and solder it, wrap it with waterproof adhesive tape, soak it in water for more than 12 hours, and measure the resistance of the insulating material with a shaking table, which is generally not less than 100 megohms.

Inspection before operation of high-lift deep well pump:

1. Check whether the circuit system is installed correctly

2. Check the monitoring instrument.

3. Check whether all bolts are loose

4. Rotate the coupling and check whether the installation company of the pump has a good

5. At the moment when the motor starts running, check whether the steering direction of the motor is consistent with the direction indicated by the steering wheel of the pump, otherwise adjust the steering direction of the motor.

6. Install the device in the well. When going down the well, use corrosion-resistant ropes to tie the cables of each section of the water pipe tightly, but do not tie them tightly to avoid damage to the cables.

7. The insulation resistance of the measuring unit to ground is not less than 5 megohms.

　　high lift deep well pumpStart:

1. Close the pump outlet gate valve and start the motor.

2. After the motor speed is normal, open the Chinese export gate valve to make the pump enter the normal economic operation of the enterprise.

3. After 4 hours of the first operation, the rapid stop adiabatic resistance should not be less than 0.5 megohms.

Monitoring during operation of high-lift deep well pump:

Check whether the reading of the monitoring instrument is normal. If the reading is abnormal, stop the vehicle for inspection. If the pump has abnormal phenomena such as vibration and noise, it shall be shut down for inspection.

shutdown of high lift deep well pump:

The new pump shall be sent to the manufacturer or professional maintenance personnel for disassembly, overhaul and maintenance every 2500 hours of operation. Check for severe wear between impeller and mouth ring. If the limit working clearance time is greater than 1mm, the mouth ring or impeller should be replaced. Check the wear of bearings and bushings. If the wear is serious, replace the pump when it is stopped for a long time, clean, handle lubrication, prevent embroidery, and store it properly. Close the outlet valve of the pump, then cut off the power supply and stop. If a second start is required, the time interval shall not be less than 5 minutes.

The above is the high lift deep well pump installation and troubleshooting, if you need to know more, you can contact us at any time! Our company has many years of experience and looks forward to your joining at any time.

How to store, transport and anti-corrosion measures for high-lift deep well pumps For well pumps containing packed wooden boxes, they should be placed on a flat concrete floor. For deep well pumps without packed wooden boxes, they should be discharged flat on the pump rack with 3 support points. Both sides shall not be suspended in the air for more than 1m.
