Description

A kind of sealer with assembled for rotating shaft
Technical field
The invention belongs to mechanical manufacturing field, and in particular to more particularly a kind of to be used for rotating shaft to a kind of sealing device Sealer with assembled.
Background technology
Mechanical seal is a kind of gland seal device of rotating machinery.For example centrifugal pump, centrifuge, reactor and compressor etc. are set It is standby.Because power transmission shaft is applied in inside and outside equipment, so, a circumferential clearance between axle and equipment be present, the medium in equipment leads to The gap is crossed to outward leakage, if pressure subatmospheric in equipment, air are revealed into equipment, it is therefore necessary to have a resistance The gland seal device of stopping leak dew.The species of axle envelope is a lot, because mechanical seal has the advantages that leakage rate is few and long lifespan, so ought Modern mechanical seal in the world is in the most important sealing mode of these equipment.Mechanical seal is called end face seal, has in country It is defined as in the standard of pass:" by least one pair of perpendicular to the end face of rotation axis in Fluid pressure and compensation mechanism elastic force The dress for preventing fluid from leaking for being bonded and being formed with respect to slip is kept under the effect of (or magnetic force) and the cooperation of auxiliary seal Put.”
Rotating shaft do not rotate or the slow-speed of revolution in the case of, only under by the effect of the elastic force of compression spring, rotating ring and stationary ring exist Low speed seal performance can be poor, causes medium in equipment outwards to reveal, meanwhile, it is necessary to ensure to connect in the rotation process of rotating shaft Part has a good lubricity, and the problem of due to poor sealing performance, cause internal lubricating oil or water to leak out, lead Cause the abrasion of mechanical seal big, equipment operation noise is big, and service life of equipment is low, and maintenance is frequent, increases cost input.
The content of the invention
In order to overcome above-mentioned technical problem, it is an object of the invention to provide a kind of combined labyrinth and carbon gland dress for rotating shaft Put, by the matching design of sealing ring and seal receptacle, rotating shaft do not rotate or the slow-speed of revolution in the case of, loudspeaker shape sealing ring can Ensure sealing by ground, solve the problems, such as rotating ring and stationary ring poor sealing performance under the low speed;Again by loudspeaker shape sealing ring with The wedge shape space formed between seal receptacle, the lubricant environment of rotating ring and stationary ring is effectively guaranteed, therefore this combination sealing fills Put, can be with the fabulous extension sealing device life-span, while strengthen sealing property.
The purpose of the present invention can be achieved through the following technical solutions:
A kind of sealer with assembled for rotating shaft, including rotating shaft, one end interference fit of rotating shaft have rotating seat and moved Ring, connected between rotating seat and rotating ring by compression spring, being fixed in rotating seat has sealing ring, the other end sealing of rotating shaft Being rotatably assorted has stationary ring and seal receptacle, and stationary ring fitting is fixed on the outer end of seal receptacle and inside sealing ring;
Sequentially passed through in the driven ring seat of the rotating shaft, compression spring, rotating ring, sealing ring, stationary ring and seal receptacle;
Described sealing ring one end stretches out is provided with loudspeaker shape sealing ring, loudspeaker provided with engaging annulus, the sealing ring other end Shape sealing ring is elastic component, rotating shaft do not rotate or the slow-speed of revolution in the case of, loudspeaker shape sealing ring can reliably ensure sealing, Solves the problems, such as rotating ring and stationary ring poor sealing performance under the low speed;
The loudspeaker shape sealing ring is fitted on seal receptacle, and certain wedge is formd between loudspeaker shape sealing ring and seal receptacle Shape space, wedge shape space can ensure the lubricant environment of rotating ring and stationary ring, therefore this combination sealing arrangement, can be prolonged with fabulous The long sealing device life-span, while strengthen sealing property;
The rotation speed change by rotating shaft, under different centrifugal actions, the company between loudspeaker shape sealing ring and seal receptacle Connect angle to change, when rotating shaft rotating speed is larger, centrifugal force causes loudspeaker shape sealing ring with seal receptacle to depart from, and avoids loudspeaker The abrasion of shape sealing ring at high speeds, now rotating ring and stationary ring can provide stable sealing property.
As the further scheme of the present invention:It is provided with the inside of the rotating seat and is used for the first placement for fixing compression spring Groove, rotating seat inner side is provided with has the piston movement to rotating ring positioned at the second standing groove above the first standing groove, the second standing groove Position-limiting action is carried out, rotating seat upper end stretches out provided with the slot for the sealing ring that is fixed.
As the further scheme of the present invention:Described rotating ring one end is provided with the first block machine for stretching out, rotating ring it is another End is connected in the presence of compression spring with stationary ring extruding, and rotating ring inner central position is provided with the second block machine to extend internally.
As the further scheme of the present invention:First block machine of the rotating ring is slidably arranged in the second standing groove;
Described compression spring one end is fixed on the first of rotating seat and places trench bottom, and the other end of compression spring is fixed on dynamic In second block machine of ring.
As the further scheme of the present invention:The sealing ring is arranged in the slot of rotating seat, engages annulus interference Coordinate in the bottom of slot.
As the further scheme of the present invention:Annular groove is provided with the stationary ring, is placed with ball in groove, stationary ring leads to Cross ball with axis of rotation to be connected, effectively reduce the cooperation resistance between stationary ring and rotating shaft.
Beneficial effects of the present invention:The present invention is not rotated or low in rotating shaft by the matching design of sealing ring and seal receptacle Under speed conditions, loudspeaker shape sealing ring can reliably ensure sealing, solve rotating ring and stationary ring sealing property under the low speed The problem of poor;When rotating shaft rotating speed is larger, centrifugal force causes loudspeaker shape sealing ring to depart from seal receptacle, avoids tubaeform sealing The abrasion of circle at high speeds, now rotating ring and stationary ring can provide stable sealing property;Wedge shape space can ensure that rotating ring With the lubricant environment of stationary ring, therefore this combination sealing arrangement can be with the fabulous extension sealing device life-span, while strengthens sealing Performance.
