Description

Technical Field

[0001] This utility model belongs to the field of motor maintenance technology, specifically relating to a pneumatic impregnation device for motor maintenance. Background Technology

[0002] In motor maintenance, most motors require rewinding, followed by an insulating varnish impregnation process. This is an indispensable part of motor maintenance, as varnish impregnation forms a uniform insulating layer on the coils and other critical components, effectively preventing electrical faults such as leakage and short circuits. Motors may be exposed to humid environments or contaminants like dust and chemicals during use. The varnish impregnation process forms a sealed protective layer, preventing moisture and contaminants from entering the motor and extending its lifespan. Varnish impregnation is categorized into pouring, dipping, and vacuum impregnation. Pouring can result in uneven varnish adhesion and internal voids, making the motor prone to electrical faults and compromising maintenance quality and lifespan. Vacuum impregnation equipment is expensive and suitable for mass motor manufacturing; using it for small-batch motor maintenance is costly. To ensure quality, a pneumatic impregnation device has been designed to improve maintenance efficiency and guarantee quality. Utility Model Content

[0003] This invention addresses the problem that when applying paint, the insulating varnish may not adhere evenly to the surface, and there may be voids inside, which could compromise the quality of motor maintenance and extend its service life.

[0004] This utility model provides the following technical solution: a pneumatic impregnation device for motor maintenance, including a paint storage tank and an oil supply pipe. A partition is provided inside the paint storage tank, which divides the paint storage tank into upper and lower layers. The lower layer is a sealed paint storage chamber, and the upper layer is a stator placement space. A silicone plate is provided in the stator placement area of ​​the partition.

[0005] The oil suction port of the oil delivery pipe is located below the liquid level in the sealed paint storage chamber, and the oil outlet of the oil delivery pipe passes through the partition and the silicone plate; the stator is placed on the silicone plate outside the oil outlet of the oil delivery pipe, and the bottom surface of the stator is sealed to the silicone plate.

[0006] An air intake assembly and an exhaust assembly are installed above the liquid level in the sealed paint storage chamber. The air intake assembly is connected to an air compressor via a high-pressure air pipe.

[0007] Furthermore, a section of the oil pipeline is located outside the paint storage tank, and control valves are installed on the section of the pipeline located outside the paint storage tank.

[0008] Furthermore, the oil pipeline includes one suction branch pipe and two outlet branch pipes. The suction branch pipe and the two outlet branch pipes are connected to a connecting branch pipe outside the paint storage tank. Control valves are installed on the connecting branch pipe between the suction branch pipe and the two outlet branch pipes.

[0009] Furthermore, a pressure gauge and a pressure regulating valve are connected in series on the high-pressure air pipe between the air compressor and the intake assembly.

[0010] Furthermore, the paint storage box includes a box body, legs, and a support platform. The legs are located at the bottom of the box body, and the support platform supports the partitions inside the box body.

[0011] Furthermore, the partition is entirely made of silicone sheet.

[0012] Furthermore, an evacuation assembly is installed on the sealed paint storage chamber.

[0013] Compared with the prior art, the advantages of this utility model are:

[0014] This utility model provides a pneumatic impregnation device for motor maintenance. Compressed air is injected into a sealed varnish storage chamber through an air intake device. Under the action of air pressure, the insulating varnish inside the sealed varnish storage chamber is forced into the stator, thus achieving stator impregnation. After impregnation, the insulating varnish flows back into the sealed varnish storage chamber under the action of gravity. Because the insulating varnish is reused, the sealed varnish storage tank reduces varnish evaporation and reduces the amount of insulating varnish used. It is suitable for stator impregnation in motor maintenance, and the use of an air pump to provide power improves labor efficiency. Attached Figure Description

A control valve 5 is installed on the connecting branch pipe between the suction branch pipe and the two outlet branch pipes.

[0026] In use, the stator 9 is placed on the silicone plate 7. The weight of the stator 9 compresses the silicone plate 7, forming a sealing surface between the bottom surface of the stator 9 and the silicone plate 7. A semi-enclosed space is formed inside the stator 9, which can hold the insulating varnish. The air compressor 10 is connected, and compressed air is injected into the sealed varnish storage chamber 1.1 through the air intake device.

The support platform supports the partition inside the box body.

[0029] The sealed varnish storage chamber 1.1 is equipped with a venting component 6. When there are many impurities in the insulating varnish, the venting component 6 is opened to drain the oil, and then new oil is poured in from the oil outlet of the oil supply pipe 2.
