Abstract

The utility model discloses a sealing structure of a grouting plunger pump. The sealing structure of the grouting plunger pump comprises a cylinder sleeve and a plunger, wherein the plunger is arranged inside the cylinder sleeve. The sealing structure of the grouting plunger pump is characterized in that an end support ring, a middle support ring, a positioning sleeve and an adjusting screw sleeve are sequentially arranged between the plunger and the cylinder sleeve from inside to outside; the outer ring of the middle support ring is provided with an oil storage tank, and the inside of the oil storage tank is uniformly provided with oil holes in the radial direction of the middle support ring; the adjusting screw sleeve is matched with an adjusting nut through threads, and one end surface of the adjusting nut is in contact with the cylinder sleeve. The sealing structure of the grouting plunger pump has the advantages of the being reasonable in structure, good in sealing effects and lubricating effects and long in service life.

Description

Grouting pump plunger sealing structure
Technical field
The utility model belongs to sealing configuration field, particularly grouting pump plunger sealing structure.
Background technique
Grouting pump plunger need to to-and-fro motion frequently in cylinder sleeve, also needs the sealing effect that keeps good simultaneously, and plunger is is comparatively easily worn and torn, and has the defect that the life-span of cylinder sleeve and plunger do not grow.
Model utility content
For overcoming the above defect of prior art, the utility model provides a kind of good sealing effect, and can keep long-time lubricated, the grouting pump plunger sealing structure of long service life.
Grouting pump plunger sealing structure of the present utility model, comprises cylinder sleeve and plunger, and described plunger is arranged in cylinder sleeve, is provided with successively from inside to outside end portion supports ring, intermediate support ring, setting sleeve and adjustment swivel nut between described plunger and cylinder sleeve; Wherein said intermediate support ring outer ring is provided with oil storage tank, in oil storage tank, has oilhole along intermediate support ring radial equipartition; Have adjusting nut at described adjustment swivel nut by screw-thread fit, an end face of described adjusting nut contacts with cylinder sleeve.The feature of this structure is to adjust the position of swivel nut with the elasticity of adjusting Sealing by adjusting nut control; Oil storage tank and oilhole coupled columns plug on reason intermediate support ring is lubricated simultaneously.
As preferred version, the bilateral symmetry of described intermediate support ring is provided with seal ring, between intermediate support ring and setting sleeve and between intermediate support ring and end portion supports ring, be provided with seal ring, oiling agent on these two the sealing intermediate support rings that the seal ring of setting can improve in pairs, improve lubrication effect, and stop bleeding of lubricant.
As preferred version, on the endoporus of described setting sleeve, have eccentric grove, the upper end of eccentric grove is minimum clearance, lower end is maximal clearance, and is symmetrically arranged with two through holes in the outer ring, top of setting sleeve, and the oval counterbore concentric with through hole.In described setting sleeve, eccentric grove part coordinates with plunger, and upper end minimum clearance is 0, and maximal clearance, lower end is 4mm.By being arranged on through hole on setting sleeve as water inlet and drainage, can to the to-and-fro motion of plunger carry out cooling and and make the outer row of mortar, larger gap, eccentric grove bottom can provide water storage effect simultaneously, holds up plunger to reduce the wearing and tearing of setting sleeve.
The beneficial effects of the utility model are: utilize intermediate support ring to improve profit and change effect, seal ring is set in intermediate support ring both sides simultaneously and reduces bleeding of lubricant; Utilize setting sleeve to support plunger, and eccentric grove raising cooling effect is set on setting sleeve, and reduce the wearing and tearing of setting sleeve; Utilize adjusting nut to adjust whole sealed environment, plunger is in all the time and seals and lubricated the optimum state.In sum, this grouting pump plunger sealing structure has rational in infrastructure, good sealing effect, and lubrication effect is good, the feature of long service life.
