Embodiment Construction

[0025] A large flow portable permanent magnet variable frequency submersible pump, such as figure 1 As shown, it is mainly composed of a permanent magnet variable frequency motor 1, a water inlet section 2, a sealing part 3, a main shaft 4, a semi-open impeller 5, a guide vane body 6, and a sliding bearing part 7.

[0026] Such as figure 1 Shown, assembly relationship and order of the present invention are as follows:

[0027] a. Put the water inlet section 2 through the main shaft 4 and install it on the permanent magnet variable frequency motor 1 and fasten it;

[0028] b. Put the sealing part 3 on the main shaft 4 and connect and fasten it with the water inlet section 2;

[0029] c. Put the semi-open impeller 5 on the main shaft 4;

[0030] d. Put the guide vane body 6 on the main shaft 4, and fasten it with the water inlet section 2;

[0031] e. Install the sliding bearing part 7 on the guide vane body 6 and fasten it.

[0032] The difference between the large-flow po...

Abstract

The invention discloses a large-flow portable permanent-magnet frequency-conversion submersible pump, which belongs to a vane-type pump in a fluid machine and aims to solve the problem that the existing submersible pump is limited in applicable scope or uneasy to transport. The submersible pump disclosed by the invention comprises a motor and a main shaft, wherein the main shaft is connected with an output shaft of the motor, the main shaft is provided with an impeller; and the motor is a permanent-magnet frequency-conversion motor, and a water inletting section which is arranged on the main shaft and fixedly connected with the permanent-magnet frequency-conversion motor is arranged between the permanent-magnet frequency-conversion motor and the impeller. According to the invention, the volume and weight of the pump are reduced while the rotating speed of the pump is improved, so that the volume and weight of the submersible pump are greatly reduced, and the application performance also can be satisfied.

Description

technical field [0001] The invention relates to a vane type pump in a fluid machine, which is used for transporting clean water, a small amount of sediment, sewage and rainwater. Background technique [0002] General vane submersible pumps, due to the traditional production method, are made of cast iron, cast steel and other materials, and ordinary submersible motors work vertically. When the water depth is not enough to submerge the motor, they cannot work safely. water. As for the large-flow submersible pump, due to the large volume and weight of the motor and traditional hydraulic components, it is inconvenient to use and carry. Contents of the invention [0003] In order to overcome the shortcomings of the existing submersible pumps, such as limited application range or inconvenient transportation, the present invention aims to provide a large-flow portable permanent magnet variable frequency submersible pump, which can well solve the above-mentioned problem. [0004...
