Abstract
The utility model provides a kind of plunger displacement configuration, and its structure is simple, in use, effectively can carry out oil extraction, avoids blocking, long service life; It comprises plunger, and in described plunger, tip portion is provided with oil drain out, and the emptying expanding channels in described oil drain out and described plunger, the tail end of described oil drain out and the joint of described plunger circular arc tip portion are circular arc.
Description
Technical field
The utility model relates to plunger pump accessory technical field, is specially a kind of plunger displacement configuration.
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, the oil drain out 2 that plunger 1 inner circle arc tip portion is provided with is connected with emptying passage 4, and valve rod 3 realizes oil suction, force feed at plunger 1 internal motion to produce pressure, but valve rod 3 and plunger 1 move, the pressure ratio that produces is larger, oil drain out 2 in plunger 1 is less, then often have little time oil extraction, cause blocking or damage, working life is short.
Summary of the invention
For the problems referred to above, the utility model provides a kind of plunger displacement configuration, and its structure is simple, in use, effectively can carry out oil extraction, avoids blocking, long service life.
Its technological scheme is such: it comprises plunger, it is characterized in that: in described plunger, tip portion is provided with oil drain out, emptying expanding channels in described oil drain out and described plunger, the tail end of described oil drain out and the joint of described plunger circular arc tip portion are circular arc.
The beneficial effects of the utility model are, valve rod is when plunger body carries out punching press, pressure oil is discharged by oil drain out, the tail end of oil drain out and the joint of described plunger circular arc tip portion are circular arc, the pressure oil then stamped out is through the oil drain out of its circular arc joint, damping force reduces, and makes the smooth and easy outflow of pressure oil, thus improves 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, in plunger 1, tip portion is provided with oil drain out 2, and valve rod 3 is when punching press is carried out in plunger 1 inside, and pressure oil is discharged by oil drain out 2, described oil drain out 2 is connected with the emptying passage 4 in described plunger 1, the tail end of described oil drain out 2 and the joint of described plunger 1 circular arc tip portion are circular arc, then the pressure oil stamped out is when the oil drain out 2 of its circular arc joint, and damping force reduces, make the smooth and easy outflow of pressure oil, thus improve working life.
