Abstract
The utility model particularly relates to a hollow plunger piston for a plunger piston pump. The hollow plunger piston is characterized by comprising a hollow pipe, a plug head and a connection segment, wherein the plug head and the connection segment are respectively arranged at the two ends of the hollow pipe, the plug head and the connection segment are of hollow structures, and the outer diameters of the hollow pipe, the plug head and the connection segment are as the same as one another. The hollow plunger piston has the advantages that 1) compared with a solid plunger piston, the weight of the hollow plunger piston is reduced by about 50%, and the material of the hollow plunger piston is saved; 2) the gravity wear is further relatively reduced due to the reduction of the weight, and the service life of a plurality of contacting parts among a filler, a guide ring and the like is prolonged; and 3) the required drive power is reduced, the energy is saved, the maintenance labor intensity is reduced, and the running cost is saved.
Description
Technical field
The utility model is specifically related to the hollow plunger that a kind of plunger pump is used.
Background technique
Important process parts in the plunger type plunger pump, the plunger of prior art all is a solid construction, weight is big, materials are many, because it is surging that price of steel product continues, the cost of production of plunger significantly increases, simultaneously because the weight of solid plunger is big, gravity wearing and tearing are also big relatively, reduced working life of contacted part with it such as filler, guide ring; Required driving force is big, and it is many to expend the energy, and maintenance labor intensity is big, the operating cost height.
The model utility content
The purpose of this utility model be solve that the solid plunger weight of prior art is big, materials are many, required driving force is big, expend the energy many, keep in repair the defective that labor intensity is big, operating cost is high, a kind of in light weight, hollow plunger that materials are few is provided.
The utility model is achieved by the following technical solution:
Be a kind of hollow plunger, it is characterized in that comprising hollow tubular, plug and linkage section three parts, described plug and linkage section are installed in the two ends of hollow tubular respectively, and plug and linkage section are solid construction, and the external diameter of hollow tubular, plug and linkage section is identical.
As a preferred version of the present utility model: the inner end of plug and linkage section is equipped with the boss that extends to hollow tubular inside.
Can or be threaded togather by welding between plug of the present utility model and linkage section and the hollow tubular.
The utlity model has following advantage:
1) than solid plunger loss of weight about 50%, economical with materials;
2) because weight saving gravity wearing and tearing also alleviate relatively, improved working life of contacted part with it such as filler, guide ring;
3) required driving force reduces energy-conservation and alleviates maintenance labor intensity, saves operating cost.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
As shown in FIG.: 1 linkage section; 2 hollow tubulars; 3 plugs; 4 boss; 5 boss.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further elaborated.
As shown in drawings: the two ends of hollow tubular 2 are pacified respectively and are welded with solid linkage section 1, plug 3, and the inner end of plug 3 and linkage section 1 is equipped with the boss 5,4 that extends to hollow tubular 2 inside.
Claims (2)
1. a hollow plunger is characterized in that comprising hollow tubular, plug and linkage section three parts, and described plug and linkage section are installed in the two ends of hollow tubular respectively, and plug and linkage section are solid construction, and the external diameter of hollow tubular, plug and linkage section is identical.
2. hollow plunger according to claim 1 is characterized in that the inner end of plug and linkage section is equipped with the boss that extends to hollow tubular inside.
