Abstract
The utility model provides a kind of pressing cover of plunger piston pump bushing dismounting device, and comprise handle and symmetrically arranged arc cutter head, described handle is fixedly connected on the outer arc of arc cutter head; The inner arc of described arc cutter head is provided with chamfering, and two forward foot in a step of arc cutter head are provided with the inclined-plane edge of a knife, is provided with oblique knife face inside two forward foot in a step of arc cutter head.The utility model solves the dismounting difficulty of gland liner, and dismounting easily causes gland liner to damage the problems such as distortion, simplifies the method for dismounting of gland liner in maintenance process, saves the device maintenance time, decrease the labor intensity of workman.
Description
Technical field
The utility model belongs to petroleum works technical field, especially relates to a kind of pressing cover of plunger piston pump bushing dismounting device.
Background technique
The gland liner of plunger pump stuffing assembly is plunger pump stuffing hold down gag, because large-scale plunger pump is high pressure pump, matching gap between its gland liner and stuffing box is less, in assembling process, gland liner bears larger extruding force, and in use scale, incrustation scale, greasy dirt etc. easily invade the gap between gland liner and stuffing box, need often to dismantle cleaning.Existing dismounting mode is by screw-driver or flat chisel dismounting gland liner, but its unloading process is complicated, and in unloading process, easily cause the facet damage of lining to be out of shape.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of pressing cover of plunger piston pump bushing dismounting device, solves pressing cover of plunger piston pump lining not quick detachable, and dismounting easily causes the problem of plunger pump stuffing gland liner deformed damaged.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of pressing cover of plunger piston pump bushing dismounting device, and comprise handle and symmetrically arranged arc cutter head, described handle is fixedly connected on the outer arc of arc cutter head; The inner arc of described arc cutter head is provided with chamfering, and two forward foot in a step of arc cutter head are provided with the inclined-plane edge of a knife, is provided with oblique knife face inside two forward foot in a step of arc cutter head.
Further, the circular arc internal diameter of described arc cutter head is less than the external diameter of gland liner.
Preferably, the inner arc chamfering of described arc cutter head is 45 degree.
Preferably, the acute angle between described oblique knife face and the end face of arc cutter head is 30 degree.
The advantage that the utility model has and good effect are: the utility model solves the dismounting difficulty of gland liner, and dismounting easily causes gland liner to damage the problems such as distortion, simplify the method for dismounting of gland liner in maintenance process, save the device maintenance time, decrease the labor intensity of workman.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is using state figure of the present utility model.
In figure:
1-handle, 2-arc cutter head, the 3-inclined-plane edge of a knife, 4-gland liner, 5-stuffing box, 6-plunger, the oblique knife face of 7-.
Embodiment
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
A kind of pressing cover of plunger piston pump bushing dismounting device as shown in Figure 1, comprise handle 1 and symmetrically arranged arc cutter head 2, described handle 1 is fixedly connected on the outer arc of arc cutter head 2; The inner arc of described arc cutter head 2 is provided with 45 degree of chamferings; Two forward foot in a step of described arc cutter head 2 are provided with the inclined-plane edge of a knife 3; Be provided with oblique knife face 7 inside two forward foot in a step of described arc cutter head 2, the acute angle between oblique knife face 7 and the end face of arc cutter head 2 is 30 degree.
The circular arc internal diameter of described arc cutter head 2 is less than the external diameter of gland liner 4.
As shown in Figure 2, gland liner 4 is socketed on plunger 6 and is arranged on stuffing box 5 one end, for compressing stuffing box 5.Adopt the process of the utility model dismounting gland liner as follows, by the arc opening of arc cutter head 2 down, arc cutter head 2 place inner arc chamfer surface is towards gland liner 4, end face back to arc cutter head 2 inner arc chamfer surface is close to the end face of stuffing box 5, and the inclined-plane edge of a knife 3 aims at the gap location of gland liner 4 and stuffing box 5; Knock the top of handle 1, the inclined-plane edge of a knife 3 enters the gap between gland liner 4 and stuffing box 5, and gland liner 4 will be overhanged stuffing box 5.
Above an embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
