Description

Technical Field

[0001] The present invention relates to the technical field of oil pump sealing, in particular to a sealing component and a pump device. Background Art

[0002] Existing oil pumps need to operate under the driving action of a rotating motor. The oil pump and the rotating motor are usually connected by a coupling. That is, the motor shaft of the rotating motor and the pump shaft of the oil pump are connected by a coupling. When the rotating motor drives the motor shaft to rotate, the motor shaft can drive the pump shaft to rotate by means of the coupling, so that the oil pump can perform an oil delivery operation.

[0003] Most existing oil pumps only seal the pump shaft through a sealing ring, and the sealing performance is general. The fiber dust in the environment is easily introduced into the chamber of the oil pump through the pump shaft. This leads to the phenomenon that glycerol leakage is likely to occur at the sealing part during use, affecting the use effect. Moreover, it is not easy to disassemble the outer shell of the oil pump, resulting in inconvenience in maintaining the sealing component and the pump device, increasing the maintenance time and reducing the effective operation rate of the equipment. Summary of the Invention

[0004] Based on this, in view of the problem of limited sealing effect mentioned above, it is necessary to provide a sealing component and a pump device.

[0005] A sealing component includes:

[0006] A mounting seat, and a mounting channel is provided inside the mounting seat;

[0007] A first connection seat, which is detachably mounted on the first side surface of the mounting seat. A first through hole communicating with the mounting channel is provided on the first connection seat. A first sealing structure surrounding the axis of the first through hole is formed between the first connection seat and the first side surface of the mounting seat;

[0008] A second connection seat, which is detachably mounted on the second side surface of the mounting seat. A second through hole communicating with the mounting channel is provided on the second connection seat.

By respectively mounting the first connection seat and the second connection seat on both sides of the mounting seat, and connecting the first connection seat and the second connection seat to the rotating motor and the pump body respectively, the rotating motor, the first connection seat, the mounting seat, the second connection seat and the pump body can be combined into a whole, so that external dust is not easily introduced into the interior of the pump body through the connection between the pump body and the pump shaft, ensuring the sealing effect.

Specifically, the second side surface of the first connecting seat 2 abuts against the first side surface of the mounting seat 1. That is, the second side surface of the first connecting seat 2 fits with the first side surface of the mounting seat 1. The inner diameter of the first through hole 23 is smaller than the inner diameter of the installation channel 14. The first through hole 23 is coaxial with the installation channel 14, and the first through hole 23 is used to accommodate part of the motor shaft 5. The inner diameter of the first through hole 23 is greater than the outer diameter of the motor shaft 5 to ensure that the motor shaft 5 can rotate smoothly relative to the first connecting seat 2. In addition, a sealing ring can be arranged between the first connecting seat 2 and the mounting seat 1 to further ensure the sealing effect between the first connecting seat 2 and the mounting seat 1.

That is, when the second connecting body 22 is located in the installation groove 13, there is a gap between the second side surface of the second connecting body 22 and the installation groove 13. So that after connecting the first connecting seat 2 with the rotary motor 7 using fittings such as bolts, this gap can accommodate the bolt head. The outer peripheral surface of the second connecting body 22 abuts against the inner peripheral surface of the installation groove 13. To ensure the structural tightness and sealing performance between the first connecting seat 2 and the mounting seat 1.

[0072] In the above embodiment, by inserting and fixing the second connecting body 22 in the installation groove 13, the first connecting seat 2 and the mounting seat 1 can be connected in a detachable manner.

In addition, since the outer diameter of the first connecting body 21 is greater than the outer diameter of the second connecting body 22, the first connecting seat 2 can first be connected to the rotary motor 7 through the second connecting body 22, so that the motor shaft 5 can pass through the first connecting seat 2 and be connected to the coupling mechanism, and then be connected to the mounting seat 1 through the first connecting body 21. So that the motor shaft 5 and the coupling mechanism will not affect the installation of the first connecting seat 2 with the rotary motor 7 and the mounting seat 1.

By respectively installing the first connecting seat 2 and the second connecting seat 3 on both sides of the mounting seat 1 and making the first connecting seat 2 and the second connecting seat 3 abut against the rotating motor 7 and the pump body 8 respectively, the rotating motor 7, the first connecting seat 2, the mounting seat 1, the second connecting seat 3 and the pump body 8 can be combined into a sealed whole, so that external dust is not easily introduced into the interior of the pump body 8 through the connection between the pump body 8 and the pump shaft 6, ensuring the sealing effect.

[0085] In one embodiment, the rotating motor 7 abuts against the inner peripheral surface of the positioning groove 26 of the first connecting seat 2. Specifically, a protruding portion is provided on the second side surface of the rotating motor 7. When the second side surface of the rotating motor 7 abuts against the first side surface of the first connecting seat 2, the protruding portion is inserted into the interior of the positioning groove 26, and the outer peripheral surface of the protruding portion abuts against the inner peripheral surface of the positioning groove 26.

[0086] In the above embodiment, by making part of the rotating motor 7 located inside the first connecting seat 2, the structural tightness and sealing performance between the first connecting seat 2 and the rotating motor 7 are further ensured.

[0087] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0088] The above embodiments merely illustrate several implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the appended claims.
