Abstract
The utility model relates to a kind of novel wear resistant hydraulic axial plunger, comprise the bulb that plunger bushing, plunger rod and plunger rod end are connected with piston shoes, described plunger bushing is have the cylindrical structural that plunger rod installs cavity, what described plunger rod installed cavity is followed successively by cylindrical cavity section, lock chambers section and straight chamber section from the inside to the outside, and the maximum diameter of described lock chambers section is less than described cylindrical cavity section maximum diameter; Described plunger rod shape is identical with described plunger rod amp-dress cavity structure, and the diameter being positioned at straight chamber section of plunger rod is less than described straight chamber section diameter; Seal ring mounting groove is provided with outside described plunger bushing.The utility model is assembled by the activity of plunger rod and plunger bushing, when plunger is operated in cylinder body, effectively can overcome assembly error, guarantees that plunger in cylinder body straight up and down, can avoid the friction with cylinder body; Simultaneously because plunger bushing surface is provided with wear resistant coating, further can improve the wear-resisting property of plunger, the repair cycle of plunger pump is increased, improve the working life of the pump housing.
Description
Technical field
The utility model relates to a kind of axial plunger, is specifically a kind of novel wear resistant hydraulic axial plunger, belongs to hydraulic planger pump equipment technical field.
Background technique
Axial plunger body a kind ofly multiple plunger is configured in a common cylinder body circumferentially, and the device making its plunger center line parallel with cylinder center line.When cylinder body rotates, by certain mechanism, plunger is done relatively reciprocating motion in the plunger hole of cylinder body, realized the function of oil suction and oil extraction by oil distribution mechanism.Axial plunger body due to structure simple, reliable operation, the advantages such as oil extraction pressure is large, are therefore widely used in productive life.
When by the motion of driven by motor oil hydraulic pump, return plate drives plunger to do piston movement in cylinder holes, realize the supercharging of liquid, the mode of this return plate is adopted to realize the piston movement of plunger, return plate can produce larger radial forces to plunger, cause plunger comparatively large with the friction of cylinder holes in piston movement process, thus make the wearing and tearing of plunger more.
Model utility content
For prior art Problems existing, the utility model proposes a kind of novel wear resistant hydraulic axial plunger, wear-resistant axial plunger be provided, reduce the wearing and tearing of plunger preferably.
The utility model solves the technological scheme of above technical problem: provide a kind of novel wear resistant hydraulic axial plunger, comprise the bulb that plunger bushing, plunger rod and plunger rod end are connected with piston shoes, described plunger bushing is have the cylindrical structural that plunger rod installs cavity, what described plunger rod installed cavity is followed successively by cylindrical cavity section, lock chambers section and straight chamber section from the inside to the outside, and the maximum diameter of described lock chambers section is less than described cylindrical cavity section maximum diameter; It is identical that described plunger rod shape and described plunger rod install cavity structure, and the diameter being positioned at straight chamber section of plunger rod is less than described straight chamber section diameter; Seal ring mounting groove is provided with outside described plunger bushing.
The technological scheme that the utility model limits further is: aforesaid novel wear resistant hydraulic axial plunger, described cylindrical cavity section is provided with oil hole and communicates with outside described plunger bushing, in plunger bushing, injecting lubricant oil when overhauling, guaranteeing the lubrication effect of plunger bushing and plunger rod.
Aforesaid novel wear resistant hydraulic axial plunger, in order to improve the wear-resisting property of plunger bushing, is provided with diamond spar wear resistant coating outside described plunger bushing.
Further, aforesaid novel wear resistant hydraulic axial plunger, the diameter that described plunger rod is positioned at described straight chamber section reduces from the inside to the outside gradually, prevents plunger rod from rubbing with straight chamber section in operation process, affects the stable of the pump housing.
The beneficial effects of the utility model: the utility model is assembled by the activity of plunger rod and plunger bushing, when plunger is operated in cylinder body, effectively can overcome assembly error, guarantee that plunger in cylinder body straight up and down, can avoid the friction with cylinder body; Simultaneously because plunger bushing surface is provided with wear resistant coating, further can improve the wear-resisting property of plunger, the repair cycle of plunger pump is increased, improve the working life of the pump housing.
Accompanying drawing explanation
Fig. 1 is the utility model schematic cross-section.
Embodiment
embodiment
The present embodiment provides a kind of novel wear resistant hydraulic axial plunger, structure as shown in Figure 1, comprise the bulb 3 that plunger bushing 1, plunger rod 2 and plunger rod end are connected with piston shoes, diamond spar wear resistant coating is provided with outside plunger bushing 1, plunger bushing is have the cylindrical structural that plunger rod installs cavity, what plunger rod installed cavity is followed successively by cylindrical cavity section 1-1, lock chambers section 1-2 and straight chamber section 1-3 from the inside to the outside, and the maximum diameter of lock chambers section is less than cylindrical cavity section maximum diameter; Cylindrical cavity section is provided with oil hole 4 and communicates with outside plunger bushing, and it is identical that plunger rod shape and plunger rod install cavity structure, and the diameter being positioned at straight chamber section of plunger rod is less than straight chamber section diameter, and the diameter that plunger rod is positioned at straight chamber section reduces from the inside to the outside gradually; Seal ring mounting groove 5 is provided with outside plunger bushing.
Assemble between the plunger bushing of the present embodiment and plunger rod and adopt the heat method that rises to assemble, the end of plunger rod is inserted in plunger bushing, when plunger moves reciprocatingly in cylinder body, the error produced due to assembling can make plunger can not operate by smooth carrying out in cylinder body, at this moment assembled by the activity of plunger rod and plunger bushing, just can eliminate assembly error, plunger is worked well, reduce the friction between plunger and cylinder body, improve the wear-resisting property of plunger.
In addition to the implementation, the utility model can also have other mode of executions.All employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
