What are the precautions for the installation and use of deep submersible pumps?

The newly purchased deep well submersible pump has many details before installation and installation.  share the precautions for the installation of the deep well pump for your reference:

1. Before installing the deep well pump, check whether the power supply voltage meets the specified standards, the deep well pump Wells and the product selection regulations. The Wells is used in compliance with the deep diameter. The water is water. If the water quality is poor, the particles and other debris cannot be used. use.

2. The micro-diameter of the deep well and large-diameter deep well pumping unit, and measure the actual depth of Wells before installation to determine whether the installation conditions of the deep well pump are met.

3. Check whether the platform is equipped with a cover that can withstand the weight of the deep well pump and the supporting outlet pipe.

4. Check whether the deep well pump assembly is good. Before installation, clear the filter of the deep well pump and check the shaft rotation of the deep well pump. If it is stuck, it is forbidden to use.

5. Use a multimeter to check whether the three-phase conductor of the deep well pump is conducting, and whether the DC resistance is approximately balanced.

6. The high power of the equipment connecting the protection switch and the control cabinet is the soft start pressure control cabinet. The pump of the deep well pump is the water pump, rubber bearing and sealed pump, which is started instantaneously in the deep well pump (not more than 1 second)! To see if the indications and indications are reversed, good water can be good if any two of the three-phase power lines are connected.

7. Install the hose rubber pad and tighten the bolts of the water pipe evenly.

8. When installing, use plastic belt or waterproof rope in each section of the water pipe to fasten the cable and water pipe, but do not pull the cable too tight.

9. Installation of deep well pump, check insulation resistance and three-conductance from switch, then check instrument and start-up equipment, close valve (small space left) start motor switch off, slowly open valve, rated current value is 90-100% Adjust the current indicator. Observe the meter to indicate if the nameplate requirements are exceeded, check the power and operation.
