Abstract
The invention discloses a non-contact combined sealing mechanism of a water eddy dynamometer, which comprises a shaft sleeve arranged between a rotor shaft and a dynamometer body, and a lining clearance spiral seal, wherein the shaft sleeve adopts multi-head screw pitch reverse threads, a radial labyrinth seal is arranged in back of the shaft sleeve and the lining clearance spiral seal, a thrower seal is arranged in back of the radial labyrinth seal, and a check ring is arranged in back of the thrower ring. The non-contact combined sealing mechanism has reasonable structure, good sealing performance and long non-contact service life, meets various operating conditions of high speed and low speed, and can be promoted for sealing various rotary machines except for dynamometers by medium.
Description
Technical field:
The utility model relates to a kind of water vortex dynamometer sealing mechanism.
Background technique:
Traditional water vortex dynamometer all adopts the sealing of rubber lip contact-type profit, and performance is restricted by Sealing linear velocity and life-span.
Summary of the invention:
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, the contactless combined sealed mechanism of the water vortex dynamometer of good seal performance.
Technical solution of the present utility model is:
The contactless combined sealed mechanism of a kind of water vortex dynamometer, it is characterized in that: comprise the axle sleeve and the spiral seal of lining clearance type that are arranged between rotor shaft and dynamometer body, its Intermediate shaft sleeve adopts bull pitch reverse thread, the radial labyrinth sealing is set after axle sleeve and the spiral seal of lining clearance type, the thrower sealing is set after the radial labyrinth sealing, after the thrower sealing, back-up ring is set.
Before axle sleeve and the spiral seal of lining clearance type, the rough vacuum adsorbent chamber is set.
The utility model is rational in infrastructure, good seal performance, and the contactless life-span is long, satisfies each operating conditions of high low speed etc., can promote to be used for all kinds of in addition mechanical mediums sealings that rotatablely move of dynamometer.
Description of drawings:
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is an embodiment's of the utility model a configuration diagram.
