Abstract
The invention provides an oil discharge structure of a plunger. The oil discharge structure is simple in structure. When the oil discharge structure is used, oil discharge can be effectively conducted, blockage is avoided, and the service life is long. The oil discharge structure comprises the plunger. An oil discharge opening is formed in the top end in the plunger and connected with an oil unloading passageway in the plunger. The joint of the tail end of the oil discharge opening and the arc-shaped top end of the plunger is in an arc shape.
Description
Technical field
The present invention relates to plunger displacement pump accessory technical field, be specially plunger displacement configuration.
Background technologyHigh-pressure plunger pump is widely used in the fields such as chemical industry, generating, papermaking, building, process is emptied inside existing piston structure, as shown in Figure 1, the oil drain out 2 that plunger 1 inner circle arc top ends 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 is relatively larger with the pressure that plunger 1 motion produces, oil drain out 2 in plunger 1 is less, then often having little time oil extraction, cause blocking or damage, service life is short.
Summary of the invention
For the problems referred to above, the invention provides plunger displacement configuration, its simple in construction, in use, can effectively carry out oil extraction, it is to avoid blocking, long service life.
Its technical scheme is such that it and includes plunger, it is characterized in that: in described plunger, top ends is provided with oil drain out, described oil drain out is connected with the emptying passage in described plunger, and the junction of the tail end of described oil drain out and described plunger circular arc top ends is circular arc.
The invention has the beneficial effects as follows, valve rod is when plunger body carries out punching press, pressure oil is discharged by oil drain out, the junction of the tail end of oil drain out and described plunger circular arc top ends is circular arc, the pressure oil then stamped out is through the oil drain out of its circular arc junction, damping force reduces so that the smooth and easy outflow of pressure oil, thus improving service life.
Accompanying drawing explanation
Fig. 1 is existing piston structure schematic diagram；
Fig. 2 is the structural representation of the present invention.
Detailed description of the invention
As shown in Figure 2, the present invention includes plunger 1, in plunger 1, top ends is provided with oil drain out 2, and time valve rod 3 carries out punching press inside plunger 1, 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 junction of the tail end of described oil drain out 2 and described plunger 1 circular arc top ends is circular arc, then the pressure oil stamped out is when the oil drain out 2 of its circular arc junction, and damping force reduces, make the smooth and easy outflow of pressure oil, thus improving service life.
