[0030] See also Figure 1 to Figure 2 As shown, according to an embodiment of the present application, an epoxy potting system is provided, including a vacuum tank, a vacuum device and a tank cover 3 switch device, the vacuum tank includes a tank body 1 and a tank cover 3, the tank cover 3 switch device is connected to the tank cover 3 to drive the tank cover 3 to cover the tank body 1 or drive the tank cover 3 to separate from the tank body 1, the vacuum device is arranged on the tank body 1, and is connected to the internal space of the tank body 1 to extract the gas in the tank body 1, the vacuum device includes at least a first vacuum pump and a second vacuum pump, the first vacuum pump is used to continuously operate under a vacuum condition, and the second vacuum pump is used to start when the air pressure value in the tank body 1 is lower than a preset pressure value.

[0031] By providing a switch device for the tank cover 3 and connecting it to the tank cover 3, the tank cover 3 can be opened and closed through the switch device for the tank cover 3, thereby avoiding the operation of manually pulling up or lowering the tank cover 3 in the prior art, thereby avoiding the risk of misoperation caused by manual operation, and ensuring a good sealing effect between the tank cover 3 and the tank body 1. By providing a vacuum device, and making the vacuum device include at least a first vacuum pump and a second vacuum pump, and making the first vacuum pump continuously operate under vacuum conditions, and the second vacuum pump being started when the air pressure value in the tank body 1 is lower than a preset pressure value, not only can the vacuuming rate be guaranteed, but also the vacuuming operation can be performed progressively, thereby improving the vacuuming speed and effectively improving the service life of the two vacuum pumps.

[0032] Among them, the epoxy potting system is used for epoxy treatment of stators and rotors of large motors and generators. Specifically, it is used for epoxy treatment of stators and rotors of large motors and generators with stator outer diameters below 3m.

[0033] In this embodiment, the effective inner diameter of the tank body 1 may be 3 meters, and the height may be 1.8 meters.

[0034] Wherein, a viewing mirror assembly 13 is provided on the tank cover 3 for observing the internal situation of the tank body 1 .

[0035] The first vacuum pump and the second vacuum pump are both connected to the inner space of the tank body 1 , so as to perform a vacuum operation on the inside of the tank body 1 .

[0036] It is understandable that the vacuum device may further include a third vacuum pump, a fourth vacuum pump, etc. The third vacuum pump and the fourth vacuum pump are also connected to the internal space of the tank body 1, thereby performing a vacuum operation on the interior of the tank body 1.

[0037] As a method, the third vacuum pump, the fourth vacuum pump, etc. can be started and stopped together with the second vacuum pump, that is, the first vacuum pump is started first, and the second vacuum pump, the third vacuum pump, and the fourth vacuum pump are started and stopped together.

[0038] As another way, the third vacuum pump can be started and stopped together with the first vacuum pump, and the fourth vacuum pump can be started and stopped together with the second vacuum pump, that is, the first vacuum pump and the third vacuum pump are started first, and the second vacuum pump and the fourth vacuum pump are started and stopped together.

[0039] As another way, the first vacuum pump, the second vacuum pump, the third vacuum pump, and the fourth vacuum pump are all started progressively. Specifically, the first vacuum pump is used to operate continuously under vacuum conditions, and the second vacuum pump is used to start when the air pressure value in the tank body 1 is lower than the first preset pressure value. The third vacuum pump is used to start when the air pressure value in the tank body 1 is lower than the second preset pressure value. The fourth vacuum pump is used to start when the air pressure value in the tank body 1 is lower than the third preset pressure value. The first preset pressure value is greater than the second preset pressure value, which is greater than the third preset pressure value.

[0040] The preset pressure value is 7000Pa~8000Pa, and the vacuum degree can be quickly drawn to a value that meets the process requirements through the first vacuum pump and the second vacuum pump.

[0041] Among them, when the vacuum operation starts, only the first vacuum pump is running, and the vacuum tank is evacuated by the first vacuum pump. When the pressure value in the vacuum tank reaches 7000Pa~8000Pa, the second vacuum pump is started, and the vacuum tank is evacuated together with the first vacuum pump, which can quickly achieve the vacuum degree to a value that meets the process requirements.

[0042] Specifically, the value required by the process is generally 500Pa, and the evacuation volume of the first vacuum pump and the second vacuum pump is 350m 3 / H, the vacuum degree can be reduced to 500Pa within 3 minutes.

[0043] The tank body 1 is provided with an installation position along the circumference of the tank mouth of the tank body 1, and a sealing ring 2 is provided on the installation position. The sealing ring 2 is sleeved on the outer circumference of the tank mouth, and the tank cover 3 switch device can drive the tank cover 3 to be pressed against the sealing ring 2. By sleeved the sealing ring 2 along the circumference of the tank mouth, the tank cover 3 switch device can drive the tank cover 3 to be pressed against the sealing ring 2, and a good sealing effect can be achieved behind the tank cover 3, ensuring that the tank body 1 has a good vacuum degree.

[0044] The safety position may be a mounting groove surrounding the outer circumference of the tank mouth, and the sealing ring 2 is arranged in the mounting groove.

[0045] Among them, the sealing ring 2 is made of elastic material. When the switch device of the tank cover 3 can drive the tank cover 3 to be pressed against the sealing ring 2, the sealing ring 2 can be deformed, thereby improving the sealing effect.

[0046] The sealing ring 2 is in the shape of a ring and is sleeved on the outer peripheral side of the tank opening along the circumferential direction of the tank opening.

[0047] The tank cover 3 is an arched structure, and the outer edge of the tank cover 3 is used to be pressed against the sealing ring 2 . When the outer edge of the tank cover 3 is used to be pressed against the sealing ring 2 , the middle part of the tank cover 3 arches in a direction away from the tank body 1 .

[0048] The outer edge of the tank cover 3 is provided with a flange 4, or the flange 4 is formed integrally with the tank cover 3. The flange 4 protrudes from the tank cover 3, so that the flange 4 can be pressed on the sealing ring 2.

[0049] The width of the flange 4 is smaller than the width of the sealing ring 2 .

[0050] When the tank cover 3 is placed on the tank body 1 , the middle portion of the tank cover 3 arches toward a side away from the tank body 1 to form an upper arch structure.

[0051] Specifically, the tank cover 3 is a substantially hollow umbrella-shaped structure.

[0052] The tank cover 3 opening and closing device includes a power part and a connecting part, and the connecting part is respectively connected to the power part and the tank cover 3, so that the power part can drive the tank cover 3 to move through the connecting part. By setting the connecting part, the power part and the tank cover 3 can be connected. By setting the power part, power can be provided for driving the connecting part and the tank cover 3 to move, thereby realizing automatic opening and closing of the tank cover 3, eliminating the operation of manually opening and closing the tank cover 3 in the prior art, saving time and labor, and avoiding the problem of poor sealing caused by manual operation errors.

[0053] Among them, the power part is connected to the tank cover 3 through the connecting part, and the power part applies force to the connecting part, so that the connecting part and the tank cover 3 move together. When the tank cover 3 is moved away from the tank body 1, it is a tank opening operation, and when the tank cover 3 is moved onto the tank body 1, it is a tank closing operation.

[0054] The power unit drives the tank cover 3 upwardly to separate from the tank body 1 through the connection part, and drives the tank cover 3 downwardly to cover the tank body 1 through the connection part.

[0055] When the tank cover 3 is closed on the tank body 1, the power unit continuously applies force to the connection part, so that the connection part drives the tank cover 3 to be pressed against the tank body 1, thereby fully ensuring a good sealing effect.

[0056] Among them, by selecting the lifting cylinder 11, the can opening time is within 60 seconds and the can closing time is within 45 seconds.

[0057] The connecting portion includes a first section 6 and a second section 7. The first section 6 and the second section 7 are arranged at an angle, and the bisector of the angle extends toward the tank cover 3. The power part is connected to the first section 6, and the tank cover 3 is connected to the second section 7, which can facilitate the power part to be arranged below the connecting portion and reduce space occupancy.

[0058] The first section 6 and the second section 7 are located in the same vertical plane.

[0059] The connection point between the first section 6 and the second section 7 is located above the tank cover 3 .

[0060] The second section 7 is parallel to the bottom surface of the can cover 3. That is, when the can cover 3 is placed on the can body 1, the second section 7 is in a horizontal state.

[0061] The angle formed by the first section 6 and the second section 7 is an obtuse angle, which can further reduce the space occupied, and when the tank cover 3 is lifted to the extreme position, it is easier to make the tank cover 3 not in a vertical state, thereby ensuring the safety of the equipment.

[0062] Specifically, in this embodiment, the angle formed by the first section 6 and the second section 7 is approximately 160°.

[0063] The second section 7 is connected to the tank cover 3 through a connecting piece, and the connecting piece is located between the first section 6 and the power unit. By providing the connecting piece, the connection position between the second section 7 and the tank body 1 is increased to ensure a good connection effect. By providing the connecting piece between the first section 6 and the power unit, the tank cover 3 can be lifted more stably.

[0064] The connecting member may be a long strip-shaped connecting rib, one end of which is connected to the second section 7 , and the other end of which is connected to the tank cover 3 .

[0065] The point where the second section 7 is connected to the tank cover 3 and the connecting piece are located on the same diameter of the tank cover 3 .

[0066] The projections of the second section 7 and the first section 6 on the outer wall of the tank cover 3 are also on the same diameter of the tank cover 3 .

[0067] The epoxy potting system also includes a support frame 8, which is connected to the tank body 1. The power unit includes a lifting cylinder 11, one end of which is hinged to the support frame 8, and the other end is hinged to the connecting part, which is hinged to the support frame 8 through a rotating shaft 10. By setting the support frame 8, a setting position is provided for the power unit and the connecting part, ensuring that the tank cover 3 can be driven to open and close smoothly.

[0068] The support frame 8 is fixedly connected to the outer wall of the tank body 1, providing a good fixing effect for the support frame 8. The tank body 1 can be fixedly connected to the ground to ensure good stability.

[0069] Among them, the support frame 8 is a frame structure, which can not only ensure the connection strength but also reduce the weight.

[0070] Among them, multiple articulated shafts are arranged on the support frame 8, one end of the lifting cylinder 11 is hinged to the support frame 8 through the articulated shaft, and the other end is also hinged to the connecting part through the articulated shaft, so that the end of the lifting cylinder 11 hinged to the support frame 8 can swing on the support frame 8 in the direction of approaching and moving away from the tank body 1.

[0071] The connecting portion is hinged to the support frame 8 via a rotating shaft 10 , so that the connecting portion can swing up and down on the support frame 8 .

[0072] Among them, this embodiment does not limit the specific structure of the support frame 8, and can satisfy that both ends of the lifting cylinder 11 are hinged on the support frame 8, and the connecting part can be hinged on the support frame 8 through the rotating shaft 10, and it is necessary to provide a good supporting and fixing effect for the lifting cylinder 11 and the connecting part.

[0073] A support plate 9 is provided on the support frame 8, and the support plate 9 is connected to the tank body 1. The support plate 9 is connected to the lifting cylinder 11. The support plate 9 is provided with a strip through groove, and the strip through groove extends along the radial direction of the tank body 1. The lifting cylinder 11 is arranged through the strip through groove, and the position of the lifting cylinder 11 in the strip through groove is adjustable along the length direction of the strip through groove.

[0074] By setting a support plate 9 and setting a strip-shaped through groove on the support plate 9, the position of the lifting cylinder 11 in the strip-shaped through groove can be adjusted along the length direction of the strip-shaped through groove. When the lifting cylinder 11 swings, it can provide a guiding effect for the lifting cylinder 11 and also provide a certain supporting effect for the lifting cylinder 11.

[0075] The support plate 9 is arranged horizontally, and the strip-shaped through groove is opened horizontally.

[0076] The strip-shaped through groove extends along the diameter direction of the tank body 1 .

[0077] The position of the lifting cylinder 11 in the strip-shaped through groove along the length direction of the strip-shaped through groove is adjustable, which means that the lifting cylinder 11 slides in the strip-shaped through groove along the length direction of the strip-shaped through groove, and when the lifting cylinder 11 needs to be fixed at a certain position, the lifting cylinder 11 can be fixed at the position. By setting the lifting cylinder 11 to be adjustable in the length direction of the strip-shaped through groove, the hinge position of the lifting cylinder 11 and the connecting part can be adjusted, or the hinge position of the connecting part and the support frame 8 can be adjusted.

[0078] Specifically, the cylinder body of the lifting cylinder 11 can be connected to the support plate 9 by a detachable connection method such as a snap connection or a latch connection, thereby fixing the lifting cylinder 11 to the support plate 9. The cylinder body of the lifting cylinder 11 can also be connected to the support plate 9 by a fixed connection method such as welding, thereby fixing the lifting cylinder 11 to the support plate 9.

[0079] A first adjustment cylinder and a second adjustment cylinder are also provided on the support frame 8. The first adjustment cylinder and the second adjustment cylinder are arranged horizontally opposite to each other. The first adjustment cylinder is located on one side of the connecting part, and the second adjustment cylinder is located on the other side of the connecting part. When the power part drives the connecting part and the tank cover 3 to move toward the tank body 1 and the distance between the tank cover 3 and the tank mouth of the tank body 1 is less than a preset distance, the first adjustment cylinder and the second adjustment cylinder are opposite to the connecting part in the horizontal direction. The first adjustment cylinder and the second adjustment cylinder are used to drive the connecting part to move in the horizontal direction so that the tank cover 3 is aligned with the tank mouth of the tank body 1.

[0080] By providing the first deviation adjustment cylinder and the second deviation adjustment cylinder, a thrust can be applied to the connection part when the connection part and the tank cover 3 deviate from the normal position, thereby adjusting the position of the connection part and the tank cover 3 and restoring the connection part and the tank cover 3 to the normal position.

[0081] The first and second yaw adjustment cylinders are respectively arranged on two opposite sides of the connecting portion. For ease of description, this embodiment is described by taking the first yaw adjustment cylinder being located on the left side of the connecting portion and the second yaw adjustment cylinder being located on the right side of the connecting portion as an example.

[0082] The first deviation adjusting oil cylinder and the second deviation adjusting oil cylinder are symmetrically arranged with respect to the connecting portion.

[0083] The first deviation adjusting oil cylinder and the second deviation adjusting oil cylinder may be of the same model.

[0084] Among them, the piston end of the first adjustment cylinder is arranged toward the side where the connecting part is located, and the piston end of the second adjustment cylinder is arranged toward the side where the connecting part is located, that is, the piston end of the first adjustment cylinder and the piston end of the second adjustment cylinder are arranged facing each other.

[0085] Among them, when the power unit drives the connecting part and the tank cover 3 to move toward the tank body 1 and the distance between the tank cover 3 and the tank mouth of the tank body 1 is less than the preset distance, the first adjustment cylinder and the second adjustment cylinder are opposite to the connecting part in the horizontal direction, that is, when the distance between the tank cover 3 and the tank mouth of the tank body 1 in the vertical direction is less than the preset distance, the connecting part moves in the vertical direction to be opposite to the first adjustment cylinder and the second adjustment cylinder.

[0086] Specifically, the preset distance can be 20 cm. When the power unit drives the connection part and the tank cover 3 to move toward the tank body 1 and the distance between the tank cover 3 and the tank mouth of the tank body 1 is less than 20 cm, the connection part moves in the vertical direction to be opposite to the first deviation adjustment cylinder and the second deviation adjustment cylinder. At this time, if the connection part and the tank cover 3 deviate to the left from the normal position, the first deviation adjustment cylinder can be used to push the connection part to the right, so that the connection part and the tank cover 3 return to the normal position. If the connection part and the tank cover 3 deviate to the right from the normal position, the second deviation adjustment cylinder can be used to push the connection part to the left, so that the connection part and the tank cover 3 return to the normal position.

[0087] The contact surfaces of the first and second adjustment cylinders for connecting with the connection part may be coated with lubricating grease to avoid excessive friction between the first and second adjustment cylinders and the connection part. The contact surfaces of the first and second adjustment cylinders for connecting with the connection part may also be provided with guide wheels or other objects for reducing friction.

[0088] It is easy for those skilled in the art to understand that, under the premise of no conflict, the above-mentioned advantageous methods can be freely combined and superimposed.

[0089] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application. The above are only preferred implementations of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and variations can be made without departing from the technical principles of the present application, and these improvements and variations should also be regarded as the protection scope of the present application.
