Description

Auxiliary device of submersible pump for well

Technical Field

The utility model relates to a immersible pump for well especially relates to the structure of the auxiliary device of immersible pump for well that can self-cleaning silt.

Background

The well submersible pump is a device used for extracting water in a well to the surface of the ground, and is widely applied to the occasions of farmland irrigation, resource exploitation, urban water supply and drainage, sewage treatment and the like.

Fig. 1 is an explanatory view of a conventional submersible pump device for a well.

As shown in fig. 1, the submersible pump device for wells comprises a pump body 100, a motor 110, a water raising pipe 120a … n, a waterproof cable 130, a cable clip 131 and the like. The water inlet 1001 of the pump body 100 is located below the pump body 100, and the water outlet 1002 is located above the pump body 100. The biggest characteristic of the well submersible pump is that the motor 110 and the pump body 100 are of an integral structure, and when water is pumped, the motor 110 and the pump body 100 are both positioned below the horizontal plane. Well water enters the pump body from a water inlet 1001 of the pump body, enters the water lifting pipe 120a from a water outlet 1002, and then reaches the ground surface after passing through each water lifting pipe.

In the actual water lifting operation, the situation that the aquifer providing well water contains more silt is often met. During the water lift, the silt is carried by the flowing high energy groundwater in the formation and seeps from the formation into the well. In the well, the flow velocity of water can descend, and energy reduces, and the silt of aquatic has a major part to subside in the bottom of the well, therefore the immersible pump for well will be buried by the silt that subsides after using a period of time, and this has reduced effective well depth, still can lead to silt to block up the water inlet of the pump body, and partial silt can fall into inside the motor even, causes the motor to damage.

For the above situation, the well is usually cleaned by taking out the submersible pump periodically for mechanical dredging, or injecting high-pressure water to the bottom of the well and then pumping out the slurry.

However, the two modes for cleaning sediment at the bottom of the well are difficult to clean, the submersible pump for the well can only be stopped producing during cleaning, regular special personnel is needed for maintenance, and labor cost is high.
