Description

Technical Field

[0001] This utility model relates to the field of shielded pump processing technology, and in particular to a stator impregnation equipment for shielded pump processing. Background Technology

[0002] A canned motor pump is a seal-free pump whose core structural features and working principle give it significant advantages in specific applications. The pump and motor are enclosed in a pressure vessel filled with the pumped medium, eliminating the rotating shaft seal of traditional centrifugal pumps. Only a static seal is used, achieving complete leak-free operation. Stator impregnation in canned motor pumps is an important process to improve the insulation performance, moisture and corrosion resistance, and mechanical strength of the stator windings. By improving insulation performance, mechanical strength, heat dissipation, and protection capabilities, stator impregnation in canned motor pumps significantly improves the reliability, efficiency, and lifespan of the motor.

[0003] In existing practical operations, the stator of a shielded pump is impregnated with paint using an impregnation equipment. The stator is placed in the impregnation equipment and impregnated with the paint solution. The viscosity and wettability of the paint solution need to be adjusted by adding different additives. The paint solution adjusted by adding additives is prone to settling after a long period of stillness, which affects the subsequent impregnation effect. Therefore, a stator impregnation equipment for processing shielded pumps is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a stator impregnation equipment for processing shielded pumps, which solves the problems mentioned in the background.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a stator impregnation equipment for processing a shielded pump, comprising an equipment shell and an equipment door hinged to the top of the equipment shell, an impregnation tank being provided inside the equipment shell, a first transmission rod being rotatably connected to the side of the impregnation tank near the bottom, a stirring blade being installed at one end of the first transmission rod, a second transmission rod being installed at the end of the stirring blade away from the first transmission rod, and a connecting pulley being installed at one end of the second transmission rod extending outward through the equipment shell.

[0006] As a further technical solution of this utility model, a servo motor is installed on one side of the equipment housing, the power output end of the servo motor is fixedly connected to the first transmission rod, and a connecting rod is symmetrically and rotatably arranged inside the paint impregnation tank near the top position.

[0007] As a further technical solution of this utility model, a placement block is installed at one end of each of the two connecting rods, and the other end of one of the connecting rods extends to the outside of the equipment housing and is connected to the connecting pulley. A placement frame is provided on the immersion tank.

[0008] As a further technical solution of this utility model, connecting pieces are symmetrically installed on the placement frame, and connecting rods are symmetrically arranged inside the placement frame near the top position. A paint-impregnating frame is installed at one end of the two connecting rods opposite to each other, and the paint-impregnating frame is uniformly provided with holes of the same size.

[0009] As a further technical solution of this utility model, the other ends of the two connecting rods extend to the outside of the placement frame and are symmetrically installed with limiting strips, and the two placement blocks are provided with slots that are adapted to the connecting rods and limiting strips.

[0010] As a further technical solution of this utility model, a maintenance door is hinged to the front of the equipment shell, and fixing plates are symmetrically installed on the equipment shell. Each of the two fixing plates is equipped with a telescopic cylinder, and the telescopic end of the telescopic cylinder is hinged to the equipment door.

[0011] This utility model provides a stator impregnation equipment for processing shielded pumps, which has the following advantages compared with the prior art:

[0012] This design discloses a stator impregnation device for processing a shielded pump. Through a set of first and second transmission rods, stirring blades, and connecting pulleys, a servo motor drives the first transmission rod to rotate left and right, causing the stirring blades to oscillate left and right within the impregnation tank. The second transmission rod, in conjunction with the connecting pulley, drives a connecting rod to rotate left and right. As the stirring blades oscillate within the impregnation tank, they agitate the impregnation solution, preventing sedimentation and ensuring a good impregnation effect. Simultaneously, the connecting pulley drives the connecting rod within the impregnation tank to rotate, causing the impregnation frame inside the frame to sway back and forth. This sways the shielded pump stator placed inside the frame, achieving uniform impregnation. This design agitates the impregnation solution, preventing sedimentation, and simultaneously drives the impregnation frame containing the stator to sway within the impregnation tank, ensuring uniform impregnation of the stator.

A maintenance door 2 is hinged to the front of the equipment shell 1. The interior of the equipment shell 1 is located below the impregnation tank 18 and is equipped with a vacuum system and a pressurization system. Fixing plates 3 are symmetrically installed on the equipment shell 1. Telescopic cylinders 4 are installed on both fixing plates 3. The telescopic ends of the telescopic cylinders 4 are hinged to the equipment door 5.

[0020] The equipment housing 1 has an impregnation tank 18 inside. A first transmission rod 11 is rotatably connected to the side of the impregnation tank 18 near the bottom. A stirring blade 12 is installed at one end of the first transmission rod 11, and a second transmission rod 13 is installed at the end of the stirring blade 12 away from the first transmission rod 11. The stirring blade 12 is located inside the impregnation tank 18 near the bottom. One end of the second transmission rod 13 extends outward through the equipment housing 1 and is connected to a connecting pulley 14. A servo motor 6 is installed on one side of the equipment housing 1. The power output end of the servo motor 6 is fixedly connected to the first transmission rod 11. The servo motor 6 is a commercially available model. The servo motor 6 drives the first transmission rod 11 to rotate left and right, and at the same time drives the stirring blade 12 to rotate left and right. The stirring blade 12 stirs the impregnation liquid inside the impregnation tank 18 to prevent sedimentation. The second transmission rod 13 rotates left and right together with the stirring blade 12, and drives a connecting rod 15 to rotate left and right through the connecting pulley 14.

The two placement blocks 16 are provided with slots that are adapted to the connecting rods 8 and the limiting strips 17. When one connecting rod 15 rotates left and right, it drives the placement block 16 to rotate left and right. The paint impregnation frame 9 placed between the placement blocks 16 swings inside the paint impregnation tank 18, causing the stator of the shielded pump to shake and impregnate inside the paint impregnation frame 9.

[0022] The working principle of this utility model is as follows: the shielded pump is placed inside the impregnation frame 9, the placement frame 7 is placed in the impregnation tank 18, the two connecting rods 8 are placed correspondingly to the placement block 16, the limiting strip 17 is inserted into the slot on the placement block 16, the equipment door 5 is closed at the top of the equipment shell 1, the servo motor 6 runs and drives the first transmission rod 11 to rotate left and right, which drives the stirring blade 12 to swing left and right together. The stirring blade 12 stirs the impregnation liquid inside the impregnation tank 18. The second transmission rod 13 drives the connecting pulley 14 to drive the transmission. The connecting pulley 14 drives a connecting rod 15 to rotate left and right together. The two connecting rods 15 cooperate with each other to make the impregnation frame 9 placed on the placement block 16 swing left and right, so that the stator of the shielded pump inside the impregnation frame 9 shakes and impregnates.
