Description
Technical field
This utility model belongs to mechanical fitting technical field, is specifically related to a kind of mechanical seal.
Background technology
In the equipment such as centrifugal pump, compressor, owing to power transmission shaft is applied in inside and outside equipment, a circumferential clearance is there is between axle and equipment, medium in equipment is leaked out by this gap, if pressure subatmospheric in equipment, then air is to equipment internal leakage, it is therefore necessary to have a gland seal device stoping leakage.Mechanical seal is exactly one of which gland seal device, it cries again end face seal, it be from least one pair of be perpendicular to the end face of rotation axis with fluid pressure and compensation mechanism elastic force or the effect of magnetic force and auxiliary seal under, keep laminating and relatively slide and the device preventing fluid from leaking that constitutes.Mechanical seal includes static components, moving ring assembly and spring, wherein static components be socketed on power transmission shaft and close-fitting in the installing hole of the pump housing, moving ring assembly close-fitting, on power transmission shaft, carries out backlash compensation by end face seal and by spring between static components and moving ring assembly.
Utility model content
The purpose of this utility model is to provide a kind of mechanical seal, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, this utility model following technical scheme of offer: a kind of mechanical seal, including power transmission shaft, rotating ring and interstage sleeve, described rotating ring is socketed with power transmission shaft, the periphery of described rotating ring is provided with rubber standoff, described rubber standoff is Z-shaped and rotating ring compact siro spinning technology, described rubber standoff be internally provided with ring support, the peripheral close-fitting of described rubber standoff has spring base, and form a groove by spring base and rubber standoff front end, it is fixedly connected with spring on described spring base, described interstage sleeve is fixing with the other end of spring to be connected, it is provided with retainer ring on described interstage sleeve, described retainer ring and groove compact siro spinning technology, the two ends of described retainer ring are connected by screw and nut.
Preferably, described ring support is provided with two groups, and lays respectively at the two ends within rubber standoff.
Preferably, the front end of described interstage sleeve and spring base compact siro spinning technology.
Technique effect of the present utility model and advantage: this mechanical seal, by rotating ring and rubber standoff and spring pedestal close-fitting, even in the state of vacuum pressure, between rotating ring and rubber standoff, rubber standoff and spring base, all will not produce the phenomenon of separation；Interstage sleeve and spring pedestal compact siro spinning technology also arrange retainer ring, prevent the air pressure in equipment from crossing this device of ambassador and loosen, do not reach the effect of sealing, and it is long that the life-span is benefited from this mechanical seal, compact conformation, effectively enhances the sealing property of mechanical seal.

Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
nullThis utility model provides a kind of mechanical seal as shown in Figure 1，Including power transmission shaft 1、Rotating ring 2 and interstage sleeve 3，Rotating ring 2 is socketed with power transmission shaft 1，The periphery of rotating ring 2 is provided with rubber standoff 21，Rubber standoff 21 in Z-shaped with rotating ring compact siro spinning technology，Rubber standoff 21 be internally provided with ring support 22，Ring support 22 is provided with two groups，And lay respectively at the two ends within rubber standoff 21，Suitably alleviate the intensity of rubber standoff 21，Extend the service life of rubber standoff 21，The peripheral close-fitting of rubber standoff 21 has spring base 23，And form a groove 32 by spring base 23 and rubber standoff 21 front end，Spring 24 it is fixedly connected with on spring base 23，Rotating ring 2 and rubber standoff 21 and spring base 23 close-fitting，Even in the state of vacuum pressure，Rotating ring 2 and rubber standoff 21、Between rubber standoff 21 and spring base 23，All will not produce the phenomenon of separation，Interstage sleeve 3 is fixing with the other end of spring 24 to be connected，The front end of interstage sleeve 3 and spring base 23 compact siro spinning technology，Guarantee the compactness of this device，Retainer ring 31 it is provided with on interstage sleeve 3，Retainer ring 31 and groove 32 compact siro spinning technology，The two ends of retainer ring 31 are connected by screw 312 and nut 311，Interstage sleeve 3 and spring base 23 compact siro spinning technology also arrange retainer ring 31，Prevent from the air pressure in equipment from crossing this device of ambassador to loosen，Do not reach the effect of sealing.
Last it is noted that the foregoing is only preferred embodiment of the present utility model; it is not limited to this utility model; although this utility model being described in detail with reference to previous embodiment; for a person skilled in the art; technical scheme described in foregoing embodiments still can be modified by it; or wherein portion of techniques feature is carried out equivalent; all within spirit of the present utility model and principle; the any modification, equivalent substitution and improvement etc. made, within should be included in protection domain of the present utility model.
