the static ring part comprises a static ring seat and a first 0-shaped sealing ring on the static ring seat;
the movable ring on the movable ring part is pressed under the action of fluid pressure and the elastic force of the compensation mechanism, so that the sealing surface of the movable ring is kept in fit with the static ring seat and slides relatively.
Preferably, the compensation mechanism comprises a spring pad and a driving ring, a spring is arranged between the spring pad and the driving ring, and the spring pad is connected with the moving ring seat.
Preferably, the drive ring is mounted and secured to the shaft by drive screws.
Preferably, the moving ring is thermally inlaid on the moving ring seat.
The beneficial effects of the utility model are as follows:
the designed single-end-face unbalanced multi-spring movable ring compensation mechanical seal is suitable for rotating in any direction of equipment, has short axial dimension, uniformly distributed end face under pressure, reliable operation and is very suitable for sealing oil chambers of sewage pumps and submersible pump motors.
Drawings
Fig. 1 is a schematic structural diagram of a single-end-face unbalanced multi-spring dynamic ring compensation mechanical seal according to the present utility model.
In the figure: the sealing device comprises a first O-shaped sealing ring, a static ring seat 2, a moving ring 3, a second 0-shaped sealing ring 4, a spring pad 5, a spring 6, a driving ring 7, a driving screw 8 and a moving ring seat 9.
Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments.
Referring to fig. 1, the single-end-face unbalanced multi-spring dynamic ring compensation mechanical seal comprises a dynamic ring part and a static ring part, wherein the dynamic ring part comprises a dynamic ring 3 and a second 0-type sealing ring 4, and the dynamic ring 3 and the second 0-type sealing ring 4 are arranged on a dynamic ring seat 9;
the static ring part comprises a static ring seat 2 and a first 0-shaped sealing ring 1 on the static ring seat 2;
the moving ring 3 on the moving ring part is pressed under the action of fluid pressure and the elastic force of the compensation mechanism, so that the sealing surface static ring seat 2 of the moving ring 3 keeps fit and slides relatively.
The compensation mechanism comprises a spring pad 5 and a driving ring 7, a spring 6 is arranged between the spring pad 5 and the driving ring 7, the spring pad 5 is connected with a movable ring seat 9, and the driving ring 7 is fixedly arranged on a shaft through a driving screw 8.
Wherein, the moving ring 3 is thermally inlaid on the moving ring seat 9.
In this embodiment, the moving ring portion and the static ring portion are perpendicular to the shaft, and the moving ring on the moving ring portion is matched with the static ring seat 2 by the auxiliary first 0-type sealing ring 1 and the second 0-type sealing ring 4 under the action of the fluid pressure and the elasticity of the compensation mechanism, so that the moving ring and the static ring seat are kept in fit and slide relatively, and fluid leakage is prevented.
Wherein the spring 6 in the driving ring 7 provides pressure and can automatically compensate the abrasion of the sealing surface of the moving ring 3, so that the moving ring is well attached to the static ring seat 2.
The drive screw 8 serves as a fixing element, also as a transmission element, and the drive screw 8 rotates the collar and the compensating gear together with the shaft.
The spring 6 is in contact with the fluid, so the design is suitable for clean fluid, the spring 6 is designed in the moving ring part, and the design mode of moving ring compensation is adopted.
In addition, the static ring part is designed to have floatability and play a role in buffering.
The designed single-end-face unbalanced multi-spring movable ring compensation mechanical seal is suitable for rotating in any direction of equipment, has short axial dimension, is uniformly distributed by pressing the end face, is reliable in operation, and is very suitable for sealing oil chambers of a sewage pump and a submersible pump motor.
The foregoing is only a preferred embodiment of the present utility model, but the scope of the present utility model is not limited thereto, and any person skilled in the art, who is within the scope of the present utility model, should make equivalent substitutions or modifications according to the technical scheme of the present utility model and the inventive concept thereof, and should be covered by the scope of the present utility model.
