Abstract
The utility model discloses a plunger pump hollow plunger for a novel high pressure cleaning machine. The hollow plunger is an integral hollow plunger, and two ends of the plunger are both sealed. The sealing end of the ball-shaped surface of the hollow plunger is provided with a clamping groove. Compared with a conventional solid plunger, the plunger pump hollow plunger for a novel high pressure cleaning machine is advantageous in that the plunger is an integral type hollow plunger, and is light in weight and low in producing cost; compared with the conventional sealing hollow plunger, the plunger is high in strength and low in product defective rate; compared with an open type hollow plunger, the plunger is little in deformation, and high in work stability.
Description
Technical field
The utility model belongs to mechanical engineering field, relates in particular to a kind of novel high-pressure washing machine plunger pump hollow plunger.
Background technique
At present, the suction booster plunger that both at home and abroad jetting machine uses is generally used three kinds of solid, totally-enclosed hollow and open type hollows.Fully closed hollow plunger two ends are all sealed, and by two hollow body, are welded; The structure of the hollow plunger of open type is one end sealing, and the other end is open.
The suction booster plunger that existing jetting machine uses respectively has its drawback:
The weight of solid plunger is larger, waste material, waste power of motor, and also installation as horizontal in suction booster is due to earth attraction effect, also to sealing system, causes monolateral friction inhomogeneous, and greatly fall at the end in working life.
Totally-enclosed hollow plunger, though solved the object of energy-saving material, before and after its welding, operation is loaded down with trivial details, defect rate is high, once and the plunger of having misapplied failure welding by the risk that has complete machine to scrap, therefore be difficult to produce in enormous quantities.
Although the simple cost of open type hollow plunger technique is lower, because one end is open, following process (heat treatment and grinding disposing) amount of deformation increases, and can not meet the actual demand of suction booster.
Model utility content
The purpose of this utility model is to provide a kind of novel high-pressure washing machine plunger pump hollow plunger, be intended to solve the various drawbacks of existing plunger-type pump of high pressure cleaner hollow plunger, reduce technique defect rate and cost of production, improve the working stability of suction booster, extend the working life of suction booster.
The utility model is achieved in that a kind of novel high-pressure washing machine plunger, and this hollow plunger is an Integral hollow plunger, and the two ends of this plunger are all sealed; On described hollow plunger ball-shaped surface closed end, offer draw-in groove.
Further, a closed end of described hollow plunger is flat mouth sealing, and another closed end is spheric;
Further, described a kind of novel high-pressure washing machine plunger pump hollow plunger, can pass through cold-forging technique disposal molding plunger embryo, and its spherical closed end can adopt friction sealing process to complete, and described draw-in groove can once complete by turning.
Further, the spherical seal closed end of described a kind of novel high-pressure washing machine plunger pump hollow plunger can adopt the local heating method that then mould pushes to complete.
The novel high-pressure washing machine plunger pump hollow plunger that the utility model provides is an Integral hollow plunger, compares lightweight, low cost of manufacture with traditional solid plunger; Compare with traditional sealing hollow plunger, intensity is high, and product defect rate is low; Compare with open type hollow plunger, be out of shape littlely, working stability is high.
Accompanying drawing explanation
Fig. 1 is the structural representation of the hollow plunger idiosome that provides of the utility model.
Fig. 2 is the structural representation of the hollow plunger that provides of the utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated:
As shown in Figure 1, 2, the utility model is achieved in that a kind of novel high-pressure washing machine plunger pump hollow plunger, is an Integral hollow plunger, and the two ends of this plunger are all sealed; One closed end A of described hollow plunger is flat mouth sealing, and another closed end is spheric; On described hollow plunger spherical closed end, offer draw-in groove D.
Further, described a kind of novel high-pressure washing machine plunger pump hollow plunger, can pass through cold-forging technique disposal molding plunger embryo, and its spherical closed end can adopt friction sealing process to complete, and described draw-in groove D can once complete by turning.
Further, the spherical seal closed end of described a kind of novel high-pressure washing machine plunger pump hollow plunger can adopt the position C of local heating hollow plunger, then with mould extruding position C moulding spherical seal closed end.
A kind of novel high-pressure washing machine plunger pump hollow plunger is as shown in Figure 1, 2 an Integral hollow plunger, and the two ends of this plunger are all sealed; One closed end A of described hollow plunger is flat mouth sealing, and another closed end is spheric; On described spherical closed end, offer draw-in groove D.This hollow plunger is installed in the plunger mat of suction booster, by described draw-in groove D, blocks, can realize the reciprocal low oscillating movement of high speed.
These are only preferred embodiment of the present utility model, not in order to limit the utility model, all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
Claims (2)
1. a novel high-pressure washing machine plunger pump hollow plunger, is characterized in that, this hollow plunger is an Integral hollow plunger, and the two ends of this plunger are all sealed; On described hollow plunger ball-shaped surface closed end, offer draw-in groove.
