Abstract
The utility model relates to a piston sealing device for the supper high pressure pump used for water jet cutting and is characterized in that: a piston head is provided with a taper angle; a taper cavity formed by the taper angle and a cylinder is filled of sealing fillings; the sealing fillings is positioned through a closing ring and a positioning pin. The sealing device is capable of obtaining a super high pressure over 400 Mpa for the piston pump, and various cutting requirements for water jet cutting are met without pressure increasing for two levels; besides, the high pressure pump has a small size and a slight weight.
Description
The utility model relates to a kind of plunger sealing device of ultrahigh pressure plunger pump.
Present superpressure pump mostly is two-step supercharging, and plunger seal is used O type circle more.Have complex structure, volume is big, to the demanding deficiency of O type circle material.
The purpose of this utility model provides a kind of two-step supercharging that need not, and just can obtain the ultrahigh pressure plunger pump of extremely high pressure.
For reaching above-mentioned purpose, the plunger sealing device of the ultrahigh pressure plunger pump that the utility model is related, it is made up of plunger, cylinder body, stuffing box packing, back-up ring and locating stud; It is characterized in that plug has a conicity angles alpha, the awl chamber that itself and cylinder body form is placed with stuffing box packing; During working stroke, the stuffing box packing compressive deformation is close to casing wall, and pressure is big more, and it is big more to be close to power, and sealing effect is good more; Need not two-step supercharging, just can obtain extremely high pressure.Oppositely during backhaul, stuffing box packing is moved with plunger by back-up ring and locating stud location.
The plunger sealing device of ultrahigh pressure plunger pump described in the utility model has simple and practical, and good sealing effect need not two-step supercharging, just can obtain extremely high pressure.
Below in conjunction with accompanying drawing and most preferred embodiment the utility model is described in detail.
Fig. 1 is the utility model plan view;
The plunger sealing device of the ultrahigh pressure plunger pump that the utility model is related, it is made up of plunger 1, cylinder body 2, stuffing box packing 3, back-up ring 4 and locating stud 5; It is characterized in that plug has a conicity angles alpha, the awl chamber that itself and cylinder body 2 form is placed with stuffing box packing 3; During working stroke, stuffing box packing 3 compressive deformations are close to casing wall, and pressure is big more, and it is big more to be close to power, and sealing effect is good more; Need not two-step supercharging, just can obtain extremely high pressure.Oppositely during backhaul, stuffing box packing 3 is moved with plunger by back-up ring 4 and locating stud 5 location.
