Description

Technical Field

[0001] This utility model belongs to the field of electric motor repair technology, and specifically relates to an automatic paint impregnation device. Background Technology

[0002] Electric motors are commonly used power equipment in industrial production, converting electrical energy into mechanical energy to drive other auxiliary devices to complete the work required for production. Impregnation of the motor stator windings is an essential process in motor maintenance, and the quality of the impregnation directly affects the safe service life and overall performance of the motor. The quality of the impregnation process plays a crucial role in improving the motor's moisture resistance, heat resistance, corrosion resistance, and thermal conductivity, as well as reducing temperature rise. Good impregnation treatment can directly improve the motor's electrical and mechanical characteristics, increasing its insulation life and service life.

[0003] Currently, the commonly used process for impregnating motor windings involves the use of traditional composite vacuum impregnation equipment for the overall impregnation of the motor stator windings. This process has the following problems: Traditional composite vacuum impregnation equipment cannot separate the stator windings from the motor housing during motor repair; the entire winding must be impregnated as a whole. The impregnation tank is large (1.4m in diameter), requiring approximately 2 tons of insulating varnish to completely immerse the stator windings and housing. Furthermore, to ensure the quality of the impregnation, the motor housing needs to be ground to remove rust and contaminants before overall impregnation. During overall impregnation, contaminants, residual varnish, and rust from the housing can enter the insulating varnish, causing contamination and affecting the overall impregnation quality. Additionally, contaminated insulating varnish in the impregnation tank has a low reusability rate, leading to waste. Utility Model Content

[0005] An automatic impregnation device, comprising

[0006] A paint impregnation tank, comprising a lower tank section and an upper tank section, wherein an isolation component is provided between the lower tank section and the upper tank section;

[0007] The paint outlet pipe passes through the isolation component and extends into the lower housing section. The paint outlet pipe is fixed to the isolation component by a sealing flange.

[0015] Compared with existing technologies, the automatic impregnation device provided by this utility model places the motor on the isolation component and in the upper section of the impregnation tank. The lower end of the motor is connected to the sealing flange on the isolation component, so that the inner cavity of the motor can communicate with the varnish outlet pipe.

[0028] See Figure 1 and Figure 2 An automatic impregnation device includes

[0029] The impregnation tank 1 includes a lower tank section 11 and an upper tank section 12, and an isolation component 2 is provided between the lower tank section 11 and the upper tank section 12.

[0030] Paint outlet pipe 3 passes through the isolation component 2 and extends into the lower housing section 11. Paint outlet pipe 3 is fixed to the isolation component 2 by sealing flange 4.

[0031] The regulating component 5 is connected to the lower housing section 11, so that the insulating varnish inside the lower housing section 11 reaches the outside of the lower housing section 11 through the varnish outlet pipe 3.

[0032] The lower section 11 of the varnish impregnation tank 1 is used to hold the insulating varnish 100. A through hole is provided on the insulating component 2, and the varnish outlet pipe 3 extends into the lower section 11 after passing through the through hole on the insulating component 2. The varnish outlet pipe 3 is fixedly connected to the through hole of the insulating component 2 by a sealing flange 4.

[0033] The motor to be impregnated is placed on the insulating component 2 and located in the upper chamber section 12 of the impregnation tank 1. The insulating component 2 serves as the impregnation platform for the motor, and the lower end of the motor is connected to the sealing flange 4 on the insulating component 2, allowing the inner cavity of the motor to communicate with the varnish outlet pipe 3. Under the action of the regulating component 5, the insulating varnish in the lower chamber section 11 enters the inner cavity of the motor through the varnish outlet pipe 3, thereby impregnating the motor stator windings. At this time, the motor does not need to be completely immersed in the impregnation tank 1, avoiding contamination of the insulating varnish by dirt and other substances attached to the motor casing during the impregnation of the motor stator windings, thus improving the impregnation quality of the motor stator windings.

[0034] See Figure 1 The bottom of the impregnation tank 1 is also provided with a slag discharge port 13, and a slag discharge component 6 is connected to the slag discharge port 13.

[0035] See Figure 1 The insulating part 2 includes a partition 21, and a silicone gasket 22 is connected to the upper surface of the partition 21.

[0036] The slag discharge port 13 and the slag discharge component 6 are used to remove slag from the insulating varnish in the impregnation tank 1. Since the entire motor is not impregnated during impregnation, but rather the motor casing serves as the impregnation seal, when the motor is installed on the impregnation platform (isolation component 2), the lower end of the motor fits tightly against the silicone gasket in the isolation component due to the motor's gravity, forming an impregnation tank equivalent to a traditional impregnation device. At this time, the insulating varnish in the lower housing section 11 enters the motor's inner cavity through the varnish outlet pipe 3 under the action of the regulating component 5. The motor stator windings are cleaned before impregnation, including the cleaning of the motor's inner cavity. After the motor stator windings have been impregnated, the insulating varnish in the motor's inner cavity flows back to the lower housing section 11 through the varnish outlet pipe 3. After multiple motor stator windings have been impregnated, some slag inevitably accumulates in the insulating varnish in the lower housing section 11. The insulating varnish discharged through the slag discharge component 6 can be reused.

[0037] See Figure 1 The control unit 5 includes an intake solenoid valve 51 and an exhaust solenoid valve 52, which are connected to the lower housing section 11.

[0038] The air intake solenoid valve 51 is used to discharge air into the lower housing section 11. The upper air pressure in the lower housing section 11 increases, and the insulating varnish is injected into the motor cavity through the varnish outlet pipe 3 after being pressurized. The insulating varnish can evenly soak the stator winding of the motor.

[0039] See Figure 1 In a specific implementation, the lower housing section 11 and the upper housing section 12 are integrally formed.

[0040] See Figure 1 The bottom of the impregnation tank 1 is connected to a support component, which includes four support legs 6.

[0041] The aforementioned automatic impregnation device uses the motor housing as the container for the insulating varnish in the impregnation tank. Compared with the impregnation tank of traditional impregnation equipment, the insulating varnish will not come into contact with the outside of the motor housing during the impregnation process, thus preventing contamination of the insulating varnish and ensuring its reuse.

[0042] The connecting pipes under the flange of the impregnation table can be perfectly shaped into a funnel. After impregnation, the insulating varnish in the sealing body (impregnation tank) can be completely drawn back into the insulating varnish tank without any residue, thus saving insulating varnish.

[0043] Next, combined Figures 1-4 This embodiment provides a method for using the above-mentioned automatic impregnation device, as detailed below:

[0044] 1. The motor is installed with the motor stator winding shell as the impregnation and sealing body for holding the insulating varnish. When the motor is placed on the impregnation platform (isolation component), the lower end of the motor fits tightly against the silicone gasket due to the motor's weight, forming an impregnation tank equivalent to a traditional impregnation equipment.

[0045] 2. The exhaust solenoid valve of the device is closed, the intake solenoid valve is connected to compressed air and opened, the upper air pressure in the lower box section 11 of the impregnation tank 1 increases, the insulating varnish is pressurized and poured into the inner cavity of the motor through the varnish outlet pipe 5, and the insulating varnish can evenly impregnate the motor stator winding.

[0046] Because there is no leakage of insulating varnish on the motor casing, it is guaranteed that the motor casing will not be contaminated by the insulating varnish. This avoids the need for grinding, rust removal, and cleaning of the motor casing, and also prevents dirt, residual varnish, and rust stains attached to the casing from entering the insulating varnish and causing contamination. Visually inspect the insulating varnish as it is slowly poured into the motor cavity. When the insulating varnish level completely covers the motor stator windings, turn off the power to the impregnation solenoid valve, stop the compressed air from entering the lower section of the impregnation tank, and the insulating varnish level will stop rising.

[0047] 3. After a period of time, once the insulating varnish has fully soaked the motor stator windings, open the exhaust solenoid valve. The insulating varnish will flow back into the lower section of the impregnation tank. After the varnish has cured, remove the motor and proceed to the next drying process.

[0048] The volume of liquid in the lower section of the varnish-impregnating tank can be adjusted according to the size of the motor. When using a small amount of insulating varnish each time, the flange opening can be sealed to maintain the viscosity of the insulating varnish. Since the entire assembly does not need to be impregnated, only a small amount of insulating varnish is required.

[0049] Throughout the impregnation process, operators use control switches to manage the soaking and reflow of the insulating varnish, making the operation simple, quick, and labor-saving. Simultaneously, the smaller surface area of ​​the insulating varnish in contact with air reduces volatile gases, minimizing the amount of unused cured insulating varnish and improving utilization.

[0050] In summary, the automatic impregnation device provided by this utility model, compared with the existing motor stator winding impregnation, can reduce the contamination rate of insulating varnish during the impregnation process, improve the impregnation quality of motor stator winding, and increase the reuse rate of insulating varnish in the later stage.
