Abstract
The utility model relates to a static ring repair tool of a medium- and high-pressure stirred tank, and the tool comprises a static ring seat, a grinding clamping fixture and a handle; the static ring seat is of a cylindrical structure; the upper diameter of the central axis hole of a cylinder is the same with the outer diameter of a static ring to be processed; an inner convex shoulder is arranged at the lower part of the central axis hole of the static ring seat; the upper end surface of the inner convex shoulder is a grinding surface; a convex ring is coaxially manufactured on the upper end of the static ring seat; the upper end surface of the convex ring has the same height with the static ring to be processed. The static ring repair tool of the medium- and high-pressure stirred tank is not affected by the mechanical deformation which is caused to a static ring sealing seat by medium pressure, so that the contacting area between the back surface of the static ring and the static ring seat reaches 85 percent, the installation requirements are fully met, the operation is simple, the use is safe and reliable, and the effect is good.
Description
Technical field
The utility model belongs to maintenance and installation field, especially a kind of mesohigh stirred tank stationary ring maintenance tool.
Background technology
Along with the development of petrochemical industry and the continuous operation of large project, mesohigh stirred tank causes abrasion to damage in long-time use, situation about needing repairing is more and more, especially the mechanical seal requirement of equipment is higher, at static pressure test, do not allow to occur leaking, common service kit is difficult to reach requirement, causes great difficulty to maintenance construction.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of simple in structure, reasonable in design, easy to operate, mesohigh stirred tank stationary ring maintenance tool that reliability is high is provided.
The utility model solves its technical problem and takes following technical scheme to realize:
A kind of mesohigh stirred tank stationary ring maintenance tool, it is characterized in that: comprise stationary seat, grind mold and handle, stationary seat is a cylinder barrel shaped structure, the upper diameter of cylindrical drum central axis hole is identical with stationary ring external diameter to be processed, the bottom of the central axis hole of stationary seat is shaped with an internal shoulder, and the upper surface of this internal shoulder is for grinding working face; The upper end of stationary seat is coaxially shaped with bulge loop, and the upper surface of this bulge loop is identical with stationary ring height to be processed.
And the internal shoulder upper end in described stationary seat is coaxially movably installed with a grinding mold, this grinding mold upper end symmetry is shaped with two handles.
And the internal shoulder upper end coaxial rotation in quiet die holder is placed stationary ring to be processed, on the radially contact-making surface of stationary ring and stationary seat, coaxial sleeve is equipped with a sealing ring, and stationary ring upper end is coaxially installed with rotating ring.
Advantage of the present utility model and good effect are:
1, the utility model grinding constructing operation is easy, has reduced greatly the disqualification rate of static pressure test after installing, and is widely used in the construction that multiple mesohigh stirred tank sealing is installed.
2, the utility model is not subject to pressure medium stationary ring seal receptacle to be caused to the impact of mechanically deform, and the stationary ring back side and stationary seat contact area are reached more than 85%, reaches installation requirement completely, and simple to operate, safe and reliable, effective.

The specific embodiment
Below in conjunction with accompanying drawing and by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of mesohigh stirred tank stationary ring maintenance tool, comprise stationary seat 1, grind mold 3 and handle 4, stationary seat is a cylinder barrel shaped structure, the upper diameter of cylindrical drum central axis hole is identical with stationary ring to be processed 7 external diameters, the bottom of the central axis hole of stationary seat is shaped with an internal shoulder 5, the upper surface of this internal shoulder is for grinding working face, in order to save the upper end of stationary seat described in material, is coaxially shaped with bulge loop 2, and the upper surface of this bulge loop is identical with stationary ring height to be processed.
While revising quiet die holder, the internal shoulder upper end in stationary seat is coaxially movably installed with a grinding mold, and this grinding mold upper end symmetry is shaped with two handles, grinds mold lower surface and smears grinding agent, for to researching the grinding working face in positive stationary seat.
Add man-hour, by handle, taken out and ground mold, the internal shoulder upper end coaxial rotation in quiet die holder is placed stationary ring to be processed, and on the radially contact-making surface of stationary ring and stationary seat, coaxial sleeve is equipped with a sealing ring 8, and stationary ring upper end is coaxially installed with rotating ring 6.
Construction method of the present utility model is:
(1) first with grinding mold, stationary seat mechanically deform amount is revised, eliminated the larger mechanically deform of quiet die holder.
(2) the grinding agent that the pure silicon carbide powder that evenly to smear by microhardness at stationary ring back be 3280HV and low viscosity turbine oil are mixed, smears and wants appropriate.
(3) put into stationary ring, the stationary ring back side is contacted with stationary seat, and touch moving carrying out grinding with have gentle hands, make that stationary ring is relative with stationary seat to be rotated, in to the process of grinding, note guaranteeing that contact-making surface relative position is constant, firmly evenly, and the relative rotation angle of stationary ring and stationary seat is not more than 8 °.
(4) to grinding after a period of time, at stationary ring back, evenly smear colouring agent, put into stationary seat to grinding.Check composition surface, contact-making surface is when reaching 85% when above, and to grinding end-of-job, next step installation is carried out in mechanical seal.
(5) carbon graphite stationary ring, through grinding, after polishing band meets the requirements, is assembled mechanical seal, carries out static pressure test.
