Problems solved by technology

When low-lift work is required, since the number of stages of the pump is fixed, when working under low-lift conditions, the pump deviates from the high-efficiency zone, resulting in low pump efficiency and increased power of the electric pump, resulting in increased energy consumption of the electric pump
When the required head increases and exceeds the s

Example Embodiment

[0022] The following are specific embodiments of the present invention in conjunction with the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0023] This combined submersible pump for wells is composed of several pump units connected in series. figure 1 As shown, the water pump unit includes a pump body 1 with a pump cavity 11. The lower end of the pump body 1 has a water inlet 12 communicating with the pump cavity 11, and the upper end has a water outlet 13 communicating with the pump cavity 11. The pump cavity 11 is provided with a submersible Motor, the lower part of the submersible motor is provided with an impeller 2.

[0024] Such as figure 1 As shown, the upper end of the pump body 1 is provided with a motor frame 3 in a through-flow structure, the water outlet 13 is provided on the motor frame 3, the lower end of the pump body 1 is provided with a pump cover 4, and t...

Abstract

The invention provides a combined submersible pump for wells, belongs to the technical field of water pumps and solves the problems that a conventional multi-stage submersible electric pump for wells can neither be combined for changes nor pump all water out. The combined submersible pump for the wells consists of a plurality of water pump units which are connected in series, wherein each water pump unit comprises a pump body with a pump chamber, a water inlet communicated with the pump chamber is formed in the lower end of the pump body, a water outlet communicated with the pump chamber is formed in the upper end of the pump body, a submersible motor is arranged in the pump chamber, and an impeller is arranged at the lower part of the submersible motor; and the water outlets of the water pump units in the next stages are communicated with the water inlets of the water pump units in the upper stages. According to the combined submersible pump for the wells, the stage number of the pump can be changed at random to meet the requirements for different lifts, and the combined submersible pump can pump all water out.

Description

Technical field [0001] The invention belongs to the technical field of water pumps, and relates to a submersible pump, particularly a combined submersible pump for wells. Background technique [0002] With the increase in water consumption and the pollution of surface water resources by human beings, the exploitation of groundwater continues to deepen, the wells are gradually deepened, and the number of submersible pumps is increasing. For this reason, people invented multi-stage submersible pumps for wells. At present, the submersible electric pump for wells produced by the enterprise is assembled by the pump part and the motor part. The motor part is located at the lower part of the whole machine, and the water inlet part is located in the middle of the connection between the motor and the pump. When the impeller stage of the pump part is determined , The power of the submersible motor is determined unchanged. [0003] The existing multi-stage submersible pumps for wells cannot ...
