Abstract
The utility model discloses a tool for mounting a stationary ring of a mechanical seal. A sleeve-type structure is adopted; and a first cavity and a second cavity are arranged inside the sleeve-type structure, wherein the first cavity is positioned at the inner side of the second cavity, a bulge is arranged at a port of the second cavity, and a rubber gasket is arranged at the inner side of the bulge. The tool for mounting the stationary ring of the mechanical seal has the beneficial effects that: the surface of the stationary ring of the mechanical seal is equally stressed in the mounting process by integrally compressing the stationary ring of the mechanical seal, mounting efficiency of the mechanical seal of a pipeline pump can be effectively improved, deformation and damage of the mechanical seal in the mounting process are greatly reduced, the service life of the mechanical seal is prolonged, and repair cost is lowered.
Description
Technical field
The utility model relates to pump housing manufacture field, specifically, specially refers to a kind of machine envelope stationary ring erecting tools.
Background technology
The machine envelope, full name mechanical seal, in industry common people's custom is called the machine envelope.It is that a kind of usefulness solves the device that seals between rotating shaft and the body.Keep fitting under the cooperation of the effect of fluid pressure and compensation mechanism elastic force (or magnetic force) and auxiliary seal perpendicular to the end face of rotation and slide relatively and constitute the device that anti-fluid is leaked by at least one pair of; Be usually used in rotary type fluid machines such as pump, compressor, reaction stirred tank, also be used for sealings such as gear-box, valve, swivel joint, marine rear shaft.Therefore, mechanical seal is a kind of general gland seal device.
Present tubing pump machine envelope stationary ring is installed and is adopted Flathead screwdriver, is pressed into machine sealing chamber through the monolateral stationary ring sealing surface is contacted, and the method is sealed the stationary ring local pressure through making machine, and causes stationary ring distortion of machine envelope or fracture.Cause and reprocess or the increase of cost.
In sum, to the defective of prior art, need a kind of machine envelope stationary ring erecting tools especially, to solve the deficiency of prior art.
The utility model content
The purpose of the utility model is to provide a kind of machine envelope stationary ring erecting tools, through the employing special structural design, thus the purpose of realization the utility model.
The utility model technical problem to be solved can realize through following technical scheme:
A kind of machine envelope stationary ring erecting tools; It is characterized in that; Adopt telescoping structure, the set inside of telescoping structure has first cavity and second cavity, and said first cavity is positioned at the inboard of second cavity; The port of second cavity is provided with annular protrusion, and the installed inside of annular protrusion has rubber washer.
Further, said rubber washer is close to the annular protrusion installation.
The beneficial effect of the utility model is: to machine envelope stationary ring reduced overall; Make machine envelope stationary ring face stressed on an equal basis in installation process, can effectively improve tubing pump machine envelope installation effectiveness, significantly reduce machine and be enclosed in distortion and damage in the installation process; The raising machine seals service life, reduces and reprocesses cost.
Description of drawings
Fig. 1 is the structural representation of the described a kind of machine envelope stationary ring erecting tools of the utility model.
Fig. 2 is the port organization figure of the described a kind of machine envelope stationary ring erecting tools of the utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with the specific embodiment, further set forth the utility model.
As depicted in figs. 1 and 2; The described a kind of machine envelope stationary ring erecting tools of the utility model adopts telescoping structure, and the set inside of telescoping structure has first cavity 110 and second cavity 210; Said first cavity 110 is positioned at the inboard of second cavity 210; The port of second cavity 210 is provided with convexity 120, and protruding 120 installed inside has rubber washer 122, and said rubber washer 122 is close to annular protrusion 120 and is installed.
The beneficial effect of the utility model is: to machine envelope stationary ring reduced overall; Make machine envelope stationary ring face stressed on an equal basis in installation process, can effectively improve tubing pump machine envelope installation effectiveness, significantly reduce machine and be enclosed in distortion and damage in the installation process; The raising machine seals service life, reduces and reprocesses cost.
More than show and described basic principle of the utility model and the advantage of principal character and the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
