Description

Technical Field

[0001] The utility model relates to the technical field of motors, and particularly relates to a motor with an anti-electrochemical corrosion function. Background Technique

[0002] An anti-electrochemical corrosion motor, that is, a motor with the ability of anti-electrochemical corrosion, is usually applied to environments with corrosive media, such as the chemical industry, marine, petroleum and other industries. This type of motor improves its service life and performance in corrosive environments through special designs and material selections.

[0003] However, in the existing anti-electrochemical corrosion motors, the gaps between the front and rear end covers and the motor housing are mostly blocked by waterproof structures to achieve a sealing effect. Since the waterproof structures are filled in the gaps, they are prone to shift under the influence of factors such as high temperature and vibration during long-term use, seriously affecting the anti-electrochemical corrosion effect. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to provide a motor with an anti-electrochemical corrosion function, in which the front end cover and the rear end cover are adhered to ensure the sealing performance between them and the motor housing, so as to solve the problems raised in the above background technique.

On the inner wall surfaces of the two open ends of the motor housing, first annular grooves are provided, and first sealing rings are installed in the first annular grooves. Annular connection grooves are provided on the inner circumferential surfaces of the first sealing rings. The front end cover and the rear end cover are respectively arranged at the two ends of the motor housing. Sealing rings are installed on the inner side surfaces of the front end cover and the rear end cover, and the sealing rings are inserted into the openings of the motor housing. Second annular grooves are provided on the outer circumferential surfaces of the sealing rings, and second sealing rings are installed in the second annular grooves. The outer circumferential surfaces of the second sealing rings are in contact with the inner side surfaces of the first sealing rings.

[0006] As a preferred technical solution, the openings of the annular connection grooves are sealed by the second sealing rings, and the annular connection grooves and the first sealing rings and the second sealing rings form an annular sealing cavity through sealing.

[0007] As a preferred technical solution, liquid injection pipes communicating with the first annular grooves are installed on the outer wall surfaces of the motor housing opposite to the first annular grooves. Liquid inlet holes communicating with the liquid injection pipes are provided on the inner wall surfaces of the annular connection grooves, and sealing plugs are threadedly connected to the outer openings of the liquid injection pipes.

[0008] As a preferred technical solution, the diameters of the sealing rings are all matched with the inner diameter of the motor housing.

[0009] As a preferred technical solution, a plurality of first fixing blocks are installed on the outer wall surfaces of the open ends of the motor housing, and a plurality of second fixing blocks are installed on the outer circumferential surfaces of the front end cover and the rear end cover. A plurality of fixing holes are provided on both the first fixing blocks and the second fixing blocks.

[0010] As a preferred technical solution, annular grooves are provided on the open end surfaces of the motor housing, and third sealing rings are installed in the grooves.

[0011] The beneficial effects of the present utility model are as follows: The structure of the present utility model is simple.

[0021] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown in

[0022] In this embodiment, the opening of the annular connection groove 11 is sealed by the second sealing ring 13, and the annular connection groove 11 forms an annular sealing cavity through the sealing of the first sealing ring 10 and the second sealing ring 13.

[0023] In this embodiment, liquid injection pipes 6 communicating with the first annular grooves are installed on the outer wall surfaces of the motor housing 1 opposite to the first annular grooves, liquid inlet holes 12 communicating with the liquid injection pipes 6 are provided on the inner wall surfaces of the annular connection grooves 11, sealing plugs 7 are threadedly connected to the openings at the outer ends of the liquid injection pipes 6, and waterproof tape can be wound between the sealing plugs and the liquid injection pipes to ensure the sealing between the two.

[0024] In this embodiment, the diameters of the sealing rings 9 are all matched with the inner diameter of the motor housing 1, so that the sealing rings can contact the inner wall surface of the motor housing to ensure the installation stability and sealing performance.

[0025] In this embodiment, multiple first fixing blocks 4 are installed on the outer wall surfaces of the open ends of the motor housing 1, multiple second fixing blocks 5 are installed on the outer circumferential surfaces of the front end cover 2 and the rear end cover 3, multiple fixing holes are provided on the first fixing blocks 4 and the second fixing blocks 5, and bolts can pass through the opposite fixing holes and cooperate with nuts to lock and fix the front end cover and the rear end cover on the motor housing.

[0026] In this embodiment, annular grooves are provided on the open end faces of the motor housing 1, and third sealing rings 8 are installed in the grooves.

[0027] During installation, the sealing rings on the front end cover and the rear end cover are inserted into the opening of the motor housing, so that the second sealing ring on the sealing ring abuts against the first sealing ring inside the motor housing. At this time, the annular connection groove can be sealed by the first sealing ring and the second sealing ring to form an annular sealing cavity.

[0028] After the above is completed, the sealing plug is opened, the waterproof glue is poured into the liquid inlet pipe, and enters the annular sealing ring through the liquid inlet hole. The solidified waterproof glue can connect the first sealing ring and the second sealing ring into a whole to ensure the sealing performance between the front end cover and the motor housing and the sealing performance between the rear end cover and the motor housing.

[0029] Among them, after the front end cover and the rear end cover abut against the open end face of the motor housing, they can contact the third sealing ring, thereby further increasing the sealing effect to prevent external corrosive liquid from entering the interior along the risk between the front end cover or the rear end cover and the motor housing to ensure the anti-electric corrosion effect.

[0030] Among them, during disassembly, the outer wall of the motor housing can be heated to melt the internal waterproof glue, and after the motor is inverted, the waterproof glue can be discharged out along the liquid injection pipe, so as to disassemble the front end cover and the rear end cover.

[0031] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any change or replacement that can be thought of without creative work should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope defined by the claims.
