Abstract
The utility model belongs to the technical field of the plunger pump, refer in particular to a plunger for plunger pump, including the plunger pipe, the one end of plunger pipe seal form the bottom, the other end is connected with the columniform connector, is provided with axially extending bore and two radial hole that are linked together with axially extending bore on the connector, two radial hole are the symmetry setting on the connector, the advantage is: simple structure becomes to produce save material when making, reduction in production cost, and intensity is high moreover, long service life.
Description
Technical field
The utility model belongs to plunger pump technique field, refers in particular to a kind of plunger pump plunger.
Background technique
Plunger is requisite component on plunger pump, common plunger comprises plunger tube and is connected to the connecting head on plunger tube, existing connecting head is provided with groove, then on the bottom of groove, make a call to a less through hole, the material that the connecting head of this structure expends is many, and cost of production is high.
Summary of the invention
It is simple that the purpose of this utility model is to provide a kind of structure, the convenient manufacturing, the plunger pump plunger that cost of production is low.
The purpose of this utility model is achieved in that
Plunger pump plunger, comprise plunger tube, one end of described plunger tube is closed and is formed bottom, the other end is connected with columniform connecting head, connecting head is provided with axial hole and two are connected with axial hole radial direction through hole, two radial direction through hole are symmetrical arranged on connecting head.
In technique scheme, described connecting head is connected by welding with after plunger tube grafting.
In technique scheme, described axial hole is bar hole, and the two long limits that bar hole is relative are the plane be parallel to each other, two relative minor faces are arc shaped surface.
In technique scheme, the axes normal of described radial direction through hole is in the plane of axial hole.
In technique scheme, the projection of the bottom of described plunger tube upwards spill camber.
In technique scheme, described plunger tube and connecting head all adopt No. 20 steel to make.
The utility model gives prominence to compared to existing technology and useful technique effect is:
1, the utility model by arranging axial hole on connecting head, replaces traditional groove, save material during the manufacturing, and then reduce cost of production by axial hole, increases the competitive ability of product.
2, plunger tube of the present utility model and connecting head adopt No. 20 steel to make, and make it have higher intensity and hardness, and connecting head is not easy to wear, increases the service life compared with traditional plunger.
Accompanying drawing explanation
Fig. 1 is perspective view of the present utility model.
Fig. 2 is one of vertical profile structural representation of the present utility model.
Fig. 3 is vertical profile structural representation two of the present utility model.
Fig. 4 is the cross-sectional structural representation of connecting head of the present utility model.
Embodiment
The utility model is further described with specific embodiment below in conjunction with accompanying drawing, see Fig. 1-Fig. 4:
Plunger pump plunger, comprise plunger tube 1, one end of described plunger tube 1 is closed and is formed bottom, the other end is connected with columniform connecting head 2, connecting head 2 is provided with axial hole 3 and two radial direction through hole 4 be connected with axial hole 3, two radial direction through hole 4 are symmetrical arranged on connecting head 2, make connecting head 2 in manufacturing time material saving by arranging axial hole 3, reduce cost of production, connecting head 2 is connected with connecting rod by two radial direction through hole 4.
Above-mentioned connecting head 2 is connected by welding with after plunger tube 1 grafting.
Above-mentioned axial hole 3 is bar hole, and the two long limits that bar hole is relative are the plane be parallel to each other, two relative minor faces are arc shaped surface.
The axes normal of above-mentioned radial direction through hole 4 is in the plane of axial hole.
The projection 5 of the bottom of above-mentioned plunger tube 1 upwards spill camber, increases the intensity of plunger tube 1.
Above-mentioned plunger tube 1 all adopts No. 20 steel to make with connecting head 2, makes plunger tube 1 and connecting head 2 have higher hardness and intensity, not easy to wear when connecting head 2 uses for a long time, increases the service life.
Above-described embodiment is only preferred embodiment of the present utility model, not limits protection domain of the present utility model according to this, therefore: all equivalence changes done according to structure of the present utility model, shape, principle, all should be covered by within protection domain of the present utility model.
