How are the conditions of use of submersible motors for wells?

GB/T 2818 "well with submersible asynchronous motor" product standard for well with submersible motor conditions are as follows.

① The motor is completely submerged in the water, and the depth of the submersible is not more than 70m.

② The water temperature is not higher than 20 ℃.

③ The solid content in water (mass ratio) shall not exceed 0. 01%.

The pH value of water is 6.5~8.5.

⑤ The content of chloride ion in water shall not exceed 400mg/L.

⑥ The inner cavity of the water-filled motor must be filled with clean water or other aqueous solution configured according to the manufacturer's regulations.

Under the above-mentioned conditions of use, the average fault-free running time of the motor is generally more than 2500h. When the use conditions are harsh, and one or more indicators such as solid content in the water, water temperature or pH value exceed the regulations, the parts of the well submersible motor will be damaged at an accelerated rate. At this time, corresponding protective measures should be taken to avoid motor failure., Shorten the service life.

Submersible pump installation and use of technical matters needing attention

Water Because the submersible pump unit is charged to dive into the water, the sealing and insulation performance of the motor must be reliable, and the installation and use technology must be strict. A little improper will cause problems, light will aggravate the wear of parts, heavy will burn the motor can not work. Therefore, the installation and use of submersible pump units must comply with the following technical points.

Submersible pump: pressurized water pump for domestic water supply

The self-filling and water absorption of the domestic water supply pump does not require the pump to be located below the lowest water level of the storage tank. The self-filling suction pump cannot be started at the lowest water level of the storage tank. Therefore, the storage tank should set a pump-starting water level according to the self-filling requirements of the pump. When the water level is above the pump-starting water level, the pump is allowed to start. When the water level is below the pump-starting water level, the pump is not allowed to start. However, the pump already in operation should continue to run and stop automatically when the pump reaches the minimum water level of the storage tank (as long as long as long as required, it can continue to operate even below the minimum water level). Therefore, the pump top discharge hole of the horizontal centrifugal pump and the first stage (section) pump body of the suction end of the vertical multistage centrifugal pump can be placed below the lowest design water level elevation.

How to effectively reduce the energy consumption of water pump

The internal surface of the water pump and the inner surface of the pressure water chamber (also known as the volute) are rusted and uneven. Surface corrosion bump will reduce the pump water volume by 7%-8%; Only steel brush and iron sandpaper or grinding wheel need to be polished smoothly during maintenance, which can reduce the fuel consumption or power consumption by 9%-14% during work.
