Abstract
The utility model discloses a double-end-face mechanical seal positioning structure, which comprises a positioning ring which is fixedly arranged on the rear side of a gland and also comprises a positioning block which is fixedly arranged at the rear end of a shaft sleeve, wherein an annular groove is formed on the positioning block; and the lower end of the positioning ring is provided with a convex ring which is matched with the annular groove. According to the double-end-face mechanical seal positioning structure, the end faces can be tightly attached and are subjected to balanced compensation after being worn, the phenomena that the sealing effect is influenced after imbalance and even the mechanical seal is damaged are avoided, the positioning structure is integrated in double-end face design, convenient to mount and reliable in seal, and accidents are reduced.
Description
Technical field
The utility model relates to the position structure of double mechanical seal.
Background technique
Mechanical seal is meant the device that prevents escape of liquid that is made up of keeping applying and slide relative under the effect of hydrodynamic pressure and compensation mechanism elastic force (or magnetic force) and under the cooperation of auxiliary seal perpendicular to the end face of spin axis at least one pair of.Elastic force load maintainer and auxiliary seal be metallicity line pipe mechanical seal we be called the wavy metal seal of tube.In light seal, use rubber corrugated pipe to make auxiliary seal in addition, rubber corrugated pipe elastic force is limited, generally need be aided with spring and satisfy and load elastic force.Present mechanical seal generally is divided into: single end face, Double End mode, but structural design is reasonable inadequately, under harsh industrial and mineral such as chemical industry, papermaking, field of smelting.
The model utility content
The purpose of the utility model provides a kind of position structure of double mechanical seal; Can let and fit between end face closely, the wearing and tearing post-compensation is balanced, prevents that unbalance back from influencing sealing effect; Even damage mechanical seal; Double End unit loading type design, installs convenient and seal more reliable, the generation of minimizing accident.
The technological scheme of the utility model is following:
The position structure of double mechanical seal includes the positioning ring that is fixedly installed on the gland rear side, also includes the positioning block that is fixedly installed in the axle sleeve rear end, has annular groove on the positioning block, and the lower end of positioning ring has the protruding circle that is complementary with annular groove.
Be connected with positioning screwn between described positioning block and the axle sleeve.
The utility model can let between end face fits closely, and the wearing and tearing post-compensation is balanced, prevent that unbalance back from influence sealing effect, even damage mechanical seal, the design of Double End unit loading type, install convenient and seal more reliable, the generation of minimizing accident.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
