Abstract
The utility model discloses a mechanical sealing structure of an oil slurry pump. The mechanical sealing structure comprises a moving ring, a sealing ring and a moving ring seat, wherein the moving ring takes the shape of a stepped shaft with a through hole; the sealing ring is sheathed on the outer side of the moving ring; the moving ring seat is arranged on one side of the moving ring; a moving ring collar is sheathed in the moving ring seat; end surfaces of the moving ring seat and a moving ring sleeve are inclined and depressed inwardly; a plurality of corrugated pipes are arranged between the moving ring seat and the moving ring sleeve; the corrugated pipe is a circular pipe; a plurality of annular corrugated sheets are arranged on the outer wall of the corrugated pipe; the moving ring is made of carbon-graphite phenol aldehyde resin; the moving ring seat and the moving ring sleeve are made of 1Cr18Ni9Ti; and the corrugated pipe is made of 1Cr18Ni12Mo2Ti. The mechanical sealing structure has the advantages of novel structure, convenience in manufacture, good mechanical performance and long service life; and circular seams between two sides of the corrugated pipe and the moving ring sleeve as well as between the two sides of the corrugated pipe and the moving ring seat are tightly and firmly welded.
Description
Technical field:
The utility model relates to the mechanical seal field, specifically is a kind of oil mud pump mechanical seal structure.
Background technique:
Mechanical seal for pump is of a great variety, and model is different, but leakage point mainly contains five places: the sealing of axle sleeve and between centers; The sealing of rotating ring and shaft room; Dynamic and static interannular sealing; To the sealing between stationary ring and stationary seat; Sealing between the end cover and the pump housing.In general, the leakage ratio between overhanging between centers, end cover and the pump housing of axle sleeve is easier to find and solve, but needs careful observation, and is particularly when working medium is liquid gas or high pressure, toxic and harmful, difficult relatively.Be difficult to debate not and judgement on remaining leaks intuitively, must on the basis of long-period of management, maintenance practice, the leakage symptom be observed, analyze, study and judge, just can draw correct conclusion.Previous mechanical seal structure only is provided with a bellows, and the end face of rotating seat, moving ring sleeve is not tilted to sunken inside, and the girth welding defective tightness of bellows both sides and moving ring sleeve, rotating seat is firm on the one hand, and the mechanical seal effect is relatively poor.The utility model novel structure, easily manufactured, effectively improve and connect good sealing effect between bellows and rotating seat, the moving ring sleeve.
The model utility content:
The purpose of this utility model provides a kind of oil mud pump mechanical seal structure, and the end slope of rotating seat, moving ring sleeve caves inward, and makes that the girth welding of bellows both sides and moving ring sleeve, rotating seat is closely firm, and mechanical seal is effective.
The technical solution of the utility model is as follows:
The oil mud pump mechanical seal structure, comprise rotating ring, seal ring, rotating seat, it is characterized in that: described rotating ring is the multidiameter shaft shape that is provided with through hole, the rotating ring outside is set with seal ring, and described rotating ring one side is provided with rotating seat, is set with the rotating ring circle in the rotating seat, the end slope of described rotating seat, moving ring sleeve caves inward, be provided with several bellowss between described rotating seat and the moving ring sleeve, described bellows is a tubular shape, and outer wall is provided with annular corrugated of multiple tracks.
Described oil mud pump mechanical seal structure is characterized in that: described rotating ring adopts graphite to soak phenolic resin, and it is 1Cr18Ni9Ti that described rotating seat, moving ring sleeve adopt material, and it is 1Cr18Ni12Mo2Ti that bellows adopts material.
The utility model has the advantages that:
The utlity model has novel structure, easily manufactured, the girth welding of bellows both sides and moving ring sleeve, rotating seat is closely firm, and mechanical strength is good, long service life.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
The oil mud pump mechanical seal structure, comprise rotating ring 1, seal ring 2, rotating seat 3, rotating ring 1 is for being provided with the multidiameter shaft shape of through hole, rotating ring 1 outside is set with seal ring 2, rotating ring 1 one sides are provided with rotating seat 3, be set with rotating ring circle 4 in the rotating seat 3, rotating seat 3, the end slope of moving ring sleeve 5 caves inward, be provided with several bellowss 6 between rotating seat 3 and the moving ring sleeve 5, bellows 6 is a tubular shape, and outer wall is provided with annular corrugated 7 of multiple tracks, and rotating ring 1 adopts graphite to soak phenolic resin, rotating seat 3, it is 1Cr18Ni9Ti that moving ring sleeve 5 adopts material, and it is 1Cr18Ni12Mo2Ti that bellows 6 adopts material.
