Description

Vacuum internal pressure test system of special water-cooling variable-frequency motor of vacuum pump

Technical Field

The utility model relates to the technical field of motor testing, in particular to a vacuum internal pressure testing system of a professional water-cooling variable-frequency motor of a vacuum pump.

Background

An air pump refers to a device or apparatus that draws air from a container being evacuated using mechanical, physical, chemical, or physicochemical means to obtain a vacuum. Generally, vacuum pumps are devices that improve, create, and maintain a vacuum in an enclosed space by various methods. In order to achieve a better effect of the vacuum pump, the vacuum pump is generally driven by connecting the vacuum pump with a variable frequency motor. At present, in order to improve the running stability of a motor, a mode of pouring glue into the motor is mostly adopted in factories to improve the performance of the motor.

When staff injects glue solution into the motor, the gas in the motor is difficult to completely discharge cleanly, and bubbles are easy to fill in part of glue solution. When a worker electrifies the motor under the condition that bubbles are filled in the glue filling liquid, electric sparks are easy to generate in the motor, splash is generated everywhere, and breakdown is easy to generate. In order to achieve the probability of motor damage, a worker needs to detect the glue filling liquid, and the glue filling liquid is easy to shield due to structures such as a stator winding and the like, so that the detection difficulty is high.

In order to solve the problems, the utility model provides a vacuum internal pressure testing system of a professional water-cooling variable-frequency motor of a vacuum pump.

The technical aim of the utility model is realized by the following technical scheme: the utility model provides a vacuum pump specialty water-cooling inverter motor vacuum internal pressure test system, includes the workstation, the mounting groove has been seted up to the upper surface of workstation, be provided with motor main part in the mounting groove, be provided with the terminal box on motor main part's the lateral wall, the upper surface of workstation is provided with the withstand voltage appearance that is used for injecting high pressure to motor main part in, the upper surface of workstation is provided with the vacuum pump, the upper surface of workstation is provided with the power, the power is connected with the vacuum pump electricity, the power is connected with withstand voltage appearance electricity.

Through adopting above-mentioned technical scheme, when the staff produced the motor, in order to improve the stability of motor operation, the staff had to make stator winding and motor housing combine closely, and at this moment, the staff had to pour into the glue solution in the motor. Then, the staff needs to detect the glue filling liquid and the stator winding. When bubbles exist in the glue filling solution or the stator winding has a damaged part, a worker applies high voltage to the motor in a semi-vacuum state, so that corona collision is easy to occur, electric spark splashing in the motor is easy to occur, and breakdown is easy to occur. At this time, the operator needs to start the vacuum pump, so that the motor main body is in a semi-vacuum state, and the pressure-resistant instrument is started to apply high pressure to the motor, and a good detection environment can be created. At this time, if the motor does not generate breakdown phenomenon, the glue filling liquid and the stator winding are both in a normal state, and no bubbles exist in the glue filling liquid.

The mounting plate 51 has a rectangular plate-like structure, and the mounting plate 51 is fixed to the bottom surface of the motor main body 2. The limiting rod 52 is of a rectangular rod-shaped structure, the limiting rod 52 is slidably arranged in the limiting groove 32, and limiting holes 54 matched with the limiting rod 52 are formed in the side wall, close to the limiting groove 32, of the mounting plate 51.

When a worker needs to detect the motor, the worker needs to interconnect the mounting plate 51 with the motor main body 2 and interconnect the bottom surface of the mounting plate 51 with the mounting groove 11. The mounting plate 51 is slid into the mounting groove 11 and then the operator slides the mounting plate 51 downward to move the motor body 2 downward with the mounting plate 51. In this process, the worker needs to manually slide the limiting rod 52, so that the limiting rod 52 completely moves into the limiting groove 32, and when the limiting groove 32 is opposite to the limiting hole 54, the limiting rod 52 moves in a direction away from the limiting groove 32 under the action of the limiting spring 53 and is finally connected with the limiting hole 54, so that the limiting rod 52 limits the mounting plate 51, and the motor main body 2 is kept stable.

In order to reduce the difficulty of the operation of the staff, the upper surface of the limit lever 52 is provided with a first inclined surface 7 on the edge where the upper surface intersects with the side wall thereof close to the mounting plate 51.

When the motor main body 2 is detected, a worker needs to take out the motor main body 2. At this time, the worker needs to slide the mounting ring 62 downward, so that the mounting ring 62 abuts against the first inclined surface 7, and the stopper rod 52 moves into the stopper groove 32 again, and the stopper rod 52 and the mounting plate 51 are separated from each other.

One end of the switch spring 8 is fixed to the bottom surface of the slider 61, and the other end of the switch spring 8 is fixed to the inner bottom wall of the chute 55.

The abutting block 81 is of a rectangular block structure, the abutting block 81 is fixed on the side wall of the motor main body 2, and a second inclined surface 82 is formed on the edge, intersecting with the side wall, far away from the motor main body 2, of the bottom surface of the abutting block 81.

When the staff slides the mounting plate 51 downwards, the motor and the abutting block 81 slide downwards along with the mounting plate 51, and then the abutting block 81 abuts against the second inclined surface 82, so that acting force between the mounting ring 62 and the inner wall of the mounting groove 11 is gradually increased, and then the mounting ring 62 is kept stable, and the probability of continuous vibration of the mounting ring 62 in the motor detection process is reduced.

In order to improve the stability of the mounting ring 62, the upper end of the outer wall of the mounting ring 62 is provided with a rubber sheet 83.

The application principle of the vacuum internal pressure testing system of the vacuum pump 3 professional water-cooling variable frequency motor in the embodiment is as follows: when the staff produces the motor, in order to improve the stability of motor operation, the staff needs to make stator winding and motor housing combine closely, and at this moment, the staff need pour into the motor and irritate the glue solution. Then, the staff needs to detect the glue filling liquid and the stator winding. When bubbles exist in the glue filling solution or the stator winding has a damaged part, a worker applies high voltage to the motor in a semi-vacuum state, so that corona collision is easy to occur, electric spark splashing in the motor is easy to occur, and breakdown is easy to occur. At this time, the operator needs to turn on the vacuum pump 3 to make the motor main body 2 in a semi-vacuum state, and start the pressure-resistant instrument 22 to apply high pressure to the motor, so that a good detection environment can be created. At this time, if the motor does not generate breakdown phenomenon, the glue filling liquid and the stator winding are both in a normal state, and no bubbles exist in the glue filling liquid. If the electric spark in the motor splashes and swings around in vacuum and is accompanied by breakdown, bubbles exist in the glue filling solution or the stator winding is damaged.

In the past, when this detection method was not available, whenever the worker continued to perform the production operation of the motor (i.e., when the motor was in a semi-vacuum state, an internal pressure was applied to the motor), a breakdown phenomenon was likely to occur, and the worker could not determine the cause of this phenomenon. Through the research of the reasons, the staff can accurately detect whether the glue filling liquid has bubbles or not, so that the use experience of the staff is improved.
