Abstract
The utility model discloses a sealing structure for a rotating main shaft penetrating through a wall of a cavity body. An outer sealing flange plate is arranged outside a cavity plate, an inner sealing flange plate is arranged inside the cavity plate, a sealing ring is arranged between the inner sealing flange plate and the outer sealing flange plate, two O-shaped sealing rings are arranged between the contact surface of the inner surface of the cavity plate and the inner sealing flange plate, one O-shaped sealing ring is arranged between the contact surface of the outer surface of the cavity plate and the outer sealing flange plate, an oil sealing ring is arranged between the inner side of the outer sealing flange plate and the rotating main shaft, and an outer oil sealing end cover covers on the oil sealing ring. The sealing structure has the advantages that the diameter of the part for the penetration of the rotating main shaft is enlarged, thicker inner and outer flange plates are used at the enlarged part and in tight fit through tension by bolts at multi positions, therefore, vibration of the plate caused by the rotation of the rotating main shaft is reduced.
Description
Technical field
The utility model relates to a kind of sealing configuration, relates in particular to the sealing configuration that a kind of rotating spindle passes the chamber body lumen wall.
Background technique
Because rotating spindle need pass the chamber wall, the chamber body lumen wall must perforate, and rotatingshaft is by behind the cavity, certainly exist certain cooperation slit, the liquid that how to guarantee inside cavity does not outflow or outside liquid does not flow into and just becomes a problem that must solve in the inside cavity, can adopt axle envelope or mechanical seal in the common mechanical design, but the axle envelope can only seal at the gap between chamber cinclides and main shaft, and mechanical seal costs an arm and a leg, and very high to axle and cavity requirement on machining accuracy, but main shaft has certain vibration in the running, thus cause the shake of cavity sheet material, destroy sealing stability, cause final leakage.
The model utility content
Technical problem to be solved of the present utility model is that the sealing configuration that passes the chamber body lumen wall at existing rotating spindle exists the problem of being unable to undergo to vibrate and causing leaking, and a kind of sealing configuration at the rotating spindle that passes the chamber body lumen wall is provided.
The utility model solves the problems of the technologies described above by following technical proposal:
A kind of sealing configuration at the rotating spindle that passes the chamber body lumen wall, comprise oil outer end-blocking lid, oil seal washer, the outside seal flange plate, the inner sealing flange plate, cavity sheet material and rotating spindle, outer installment outside seal flange plate at cavity sheet material, in the inside of cavity sheet material the inner sealing flange plate is set, and between inner sealing flange plate and outside seal flange plate, a seal ring is set, between the internal surface of cavity sheet material and inner sealing flange plate surface of contact, two O RunddichtringOs are set, between the outer surface of cavity sheet material and outside seal flange plate surface of contact, an O RunddichtringO is set, externally between sealing flange inboard and the rotating spindle oil seal washer is set, and cover at oil seal washer upper cover one oil outer end-blocking, oil outer end-blocking lid is affixed with the outside seal flange plate, the outside seal flange plate, cavity sheet material and inner sealing flange plate three are affixed with some bolts.
Described oil seal washer is a TC shape oil sealing standard piece.
The utility model has the advantages that, pass the diameter of the rotating spindle of cavity sheet material by the place by increase, and add general goal use thicker in, the outside seal flange plate is strained by the many places bolt and is closely cooperated, reduce sheet material and rotate the effect of jitter that causes because of rotating spindle, interior, health level O type circle is added with the gap sealing between flange plate and the cavity sheet material in external flanges dish and cavity sheet material contact position many places, also with the sealing of the junction between the flange of inside and outside, use outside TC profile shaft envelope and external shaft end-blocking lid to stop liquid between rotating spindle and outside seal flange plate, to leak simultaneously.Even oil seal washer is owing to wearing and tearing cause leaking, also can simply change oil sealing, thereby assurance equipment comes into operation fast from the outside.
This decoration structure features simple design, processing technology is simple, and it is with low cost, pass through the design of bowl-type cleverly of the intermediate portion of inner sealing flange plate simultaneously, increase the area of passage between axle and the inner sealing flange plate, made the cleaning dead angle at this place reduce to minimum and assurance is rinsed well and avoided material residual as far as possible.
