Ultra-light portable bucket type submersible electric pump

Abstract

The invention provides an ultra-light portable bucket type submersible electric pump. The ultra-light portable bucket type submersible electric pump can be ingeniously combined with a configured medium-and-high-speed permanent magnetic motor and a special permanent magnetic motor high-frequency variable-frequency controller to have the function of a submersible pump and the performance of being high in efficiency, small in size, low in weight and the like of a medium-and-high-speed permanent magnetic pump and can also be ingeniously combined with a configured specially-made asynchronous motor to have the performance of being high in universality, low in cost, convenient to use, high in efficiency, small in size and low in weight. In addition, a novel integrated semispherical bucket pump body guide vane set is adopted for the internal structure of the ultra-light portable bucket type submersible electric pump, an efficient centrifugal type closed impeller or an opened impeller is adopted as the matched impeller, an integrated inner water passing outer bucket body made of stainless steel materials or high-strength war industry alloy aluminum materials is adopted on the outer portion, and an internal design structure is adopted for a motor part of the pump. The performance of being compact in structure, high in efficiency, small in size, low in weight and the like can be achieved, the ultra-light portable bucket type submersible electric pump is convenient to use, multiple ultra-light portable bucket type submersible electric pumps can be connected in series for use, and the lift is higher.

Description

technical field [0001] The invention relates to the technical field of submersible pumps, in particular to an ultra-light portable drum type submersible electric pump. Background technique [0002] A submersible pump is a type of water pump in which both the impeller of the pump body and the motor driving the impeller are submerged in water. Ordinary submersible pumps have a large volume due to their complex structure. At the same time, due to traditional manufacturing methods, the pump body is made of cast iron or cast steel, which is heavy and inconvenient to move. The most common type of submersible pump is to work vertically. When the water depth is not enough to submerge the motor, it will affect the normal operation of the submersible, which makes the submersible pump work in high demand and narrows the scope of use. Therefore, ordinary submersible pumps have disadvantages such as heavy weight, large volume, low efficiency, and difficulty in moving. Contents of the ...

Ordinary submersible pumps have a large volume due to their complex structure. At the same time, due to traditional manufacturing methods, the pump body is made of cast iron or cast steel, which is heavy and inconvenient to move.

The most common type of submersible pump is to work vertically. When the water depth is not enough to submerge the motor, it will affect the normal operation of the submersible, which makes the submersible pump work in high demand and narrows the scope of use.

Therefore, ordinary submersible pumps have the disadvantages of heavy weight, large volume, low efficiency, and difficult movement.
