Background technology
The prior art of the technical field, in United States Patent (USP) (US3698726), discloses a kind of shifting for reciprocating pump
The sealing of lever part and lubricating arrangement.The device is made up of the filling sealing of multiple sealing rings, and sealing ring is closely mounted in movement
Around rod member, sealing ring is made up of politef and fiber screen.This sealing device, due to being to adopt politef
Filling with fiber screen is sealed, and there will necessarily be certain gap, so can not prevent high and low between mobile rod member and charges
The leakage calmed the anger, and for liquid there is also certain leakage；Although the sealing device employs politef etc
Self-lubricating material, but solid friction, life-span are shorter；And between this sealing device charges and mobile rod member between
Gap requires higher.In addition in Japan Kokai (clear 58-68554), one kind is disclosed again in reciprocating metal shaft
Device for sealing magnetic fluid, add magnetic in the uniform dielectric that the device is made up of the big liquid of surface tension, so as to structure
Reaching the effect of sealing, uniform dielectric is hydrargyrum to jellied magnetic fluid, in the axial direction of reciprocating metal shaft, can
Segmentation constitutes magnet fluid sealing, and places between adjacent magnetic fluid section by based on fiber, plastics, rubber and other materials
Want elastic packing made by the composite of composition.This device, be not suitable for rod member move back and forth speed it is higher when because by
In the friction of magnetic fluid, substantial amounts of heat is produced, magnetic fluid can be caused lamination occur, so that the magnetic property of sealing is significantly
Decline, in addition due also to when the reciprocal speed of mobile rod member is high, due to powerful inertia, having exceeded magnetic liquid and permanent magnetic
Magnetic liquid can be taken out of by the captivation between body, so as to cause sealing property to decline；As uniform dielectric adopts hydrargyrum, this
For the workman for installing and repair can bring certain infringement, and to, during the sealing of some working medium, also easily there is chemical reaction,
And cause to seal magnetic property decline；And as technologic factor affects, the pressure voltage of magnet fluid sealing is not high.
Utility model content
The purpose of this utility model be provide it is a kind of can the device that declines of anti-cylinder sealing magnetic, to solve above-mentioned background
In technology, cylinder is produced substantial amounts of heat, magnetic fluid can be caused lamination occur due to the friction of magnetic fluid, so that sealing
Magnetic property be greatly reduced, in addition due also to when the reciprocal speed of mobile rod member is high, due to powerful inertia, having exceeded magnetic
Magnetic liquid can be taken out of by the captivation between liquid and permanent magnet, the problems such as so as to cause sealing property to decline.
For achieving the above object, this utility model provides following technical scheme：
It is a kind of can the device that declines of anti-cylinder sealing magnetic, including mobile rod member and sleeve, the sleeve lining are provided with ring
Shape groove, the annular groove bottom are provided with flexible ring, be provided with slip ring, be provided with gas collection above the slip ring above the flexible ring
Ring, the two ends of the collector ring are fixedly connected with and are fixedly connected with elastomeric element, and one end of the elastomeric element is fixedly connected with
Cannelure, is provided with magnetic rings above the collector ring, the magnetic rings upper surface is provided with magnetic powder, and the mobile rod member is located at magnetic powder
Top.
Preferably, the magnetic rings inner cylinder face is provided with annular groove, and the external cylindrical surface of the magnetic rings is provided with convex
Edge.
Preferably, the elastomeric element is constantly in compressive state.
Compared with prior art, the beneficial effects of the utility model are：
This utility model enables what magnetic rings more fastened to be connected with mobile rod member by arranging flexible ring, setting slip ring
Slide for collector ring, the air pressure that collector ring and elastomeric element can be broken out with balance cylinder inside is set, arranging annular groove makes magnetic
Magnetic powder in property ring is unlikely to leak, and this device pressure voltage is higher, almost No leakage, long service life, easy to maintenance, by axial direction
Movement velocity affects little, compact conformation, and using reliability, low cost, and countershaft requirement on machining accuracy is not high.
