Abstract
The utility model provides a kind of plunger anti-abration structure, and its structure is simple, in use, can adapt to more high wear resistance, thus improves working life; It comprises plunger, and described plunger body is front narrow rear wealthy convex structure, and front narrow end and the rear wealthy end intersection of described plunger are provided with abrasive rubber.
Description
Technical field
The utility model relates to plunger pump accessory technical field, is specially a kind of plunger anti-abration structure.
background techniquehigh-pressure plunger pump is widely used in the fields such as chemical industry, generating, papermaking, building, process is emptied in existing piston structure inside, as shown in Figure 1, valve rod 3 realizes oil suction, force feed at plunger 1 internal motion to produce pressure, but in movement process, produce between valve rod 3 and plunger 1 inside and rub, wear and tear larger, then working life is short.
Summary of the invention
For the problems referred to above, the utility model provides a kind of plunger anti-abration structure, and its structure is simple, in use, can adapt to more high wear resistance, thus improves working life.
Its technological scheme is such: it comprises plunger, it is characterized in that: described plunger body is front narrow rear wealthy convex structure, and front narrow end and the rear wealthy end intersection of described plunger are provided with abrasive rubber.
The beneficial effects of the utility model are, plunger body is front narrow rear wealthy convex structure, valve rod is when plunger body carries out punching press, still gap is left between wealthy end after valve rod and plunger body, effectively prevent friction, front narrow end and the rear wealthy end intersection of plunger are provided with abrasive rubber, in valve rod punching press, prevent plunger and valve rod damaged in collision, thus improve working life.
Accompanying drawing explanation
Fig. 1 is existing piston structure schematic diagram;
Fig. 2 is structural representation of the present utility model.
Embodiment
As shown in Figure 2, the utility model comprises plunger 1, plunger 1 inside is front narrow rear wealthy convex structure, valve rod 3, when punching press is carried out in plunger 1 inside, still leaves gap between valve rod 3 and the inner rear wealthy end of plunger 1, effectively prevents friction, front narrow end and the rear wealthy end intersection of plunger 1 are provided with abrasive rubber 2, in valve rod 3 punching press, prevent plunger 1 and valve rod 3 damaged in collision, thus improve working life.
