Abstract
The utility model discloses a plunger piston of a reciprocating pump. A coaxial deep hole is arranged inside a plunger piston body. Since the plunger piston of the reciprocating pump is in a hollow structure, the weight of the plunger piston can be greatly reduced, so the abrasion of the filling and the eccentricity of the plunger piston can be reduced, the leakage of the filling can be reduced, and the service life of the filling can be improved.
Description
Technical field
The utility model relates to a kind of plunger of reciprocating pump.
Background technique
Reciprocating pump is one of visual plant of industries such as chemical fertilizer, its working pressure height, and sealing difficulty is big.Because in reciprocating pump, plunger is the overhang of single fulcrum, and a part of weight of plunger is born by filler, therefore, causes filler bottom serious wear easily and makes plunger off-centre, increases the packing leaking amount, shortens filler working life.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of plunger that can have than the reciprocating pump of light weight under the prerequisite that ensures volume.
For this reason, the plunger of the reciprocating pump that the utility model provides, plunger body inside has coaxial deep hole.
Because the reciprocating pump plunger that the utility model provides is a hollow-core construction, therefore the weight of plunger be can reduce significantly, thereby filler wearing and tearing and plunger off-centre alleviated, reduce the leakage rate of filler, the working life of improving filler.
Description of drawings
Fig. 1 is provided with the not piston structure cross-sectional schematic of the reciprocating pump of threaded plug.
Fig. 2 is the piston structure cross-sectional schematic that is provided with the reciprocating pump of threaded plug.
Fig. 3 is the piston structure cross-sectional schematic that the reciprocating pump of plug is not set.
Embodiment
As shown in Figure 1, plunger body 1 inside of the plunger of the reciprocating pump that provides of the utility model has coaxial deep hole 2.Coaxial deep hole 2 has the outlet 3 of outside opening, and the outlet port of coaxial deep hole 2 is provided with plug 4, and plug 4 forms welding with the outlet port of plunger body 3.As shown in Figure 2, plug 4 and outlet 3 in the present embodiment is connected the mode that can also adopt screw-thread fit.Perhaps, plug 4 can also be set as shown in Figure 3.
Claims (3)
1. the plunger of a reciprocating pump, it is characterized in that: plunger body (1) inside has coaxial deep hole (2).
2. the plunger of reciprocating pump according to claim 1, it is characterized in that: described coaxial deep hole (2) has the outlet (3) of outside opening.
