Description
Technical field
The present invention relates to high-pressure pump manufacturing technology field, particularly relate to a kind of high-pressure pump plunger.
Background technology
High-pressure pump is to provide high voltage power, for New Buildings, highway, subterranean railway etc. for the mud that sprays water with high pressure
Aspect, high-pressure pump also can be used in water under high pressure and take the photograph stream auxiliary rock coal breakage, the cleaning of underground piping, and high-pressure water jet is bored a hole or it
He needs with highly pressurised liquid is the field of power.Generally, high-pressure pump primary structure includes power end and fluid end two
Point, fluid end includes pump head and pressurized cylinder, and high pressure pump power end band dynamic crankshaft rotates, and promotes the plunger making to be positioned in pressurized cylinder
Making straight reciprocating motion, the keying effect at pump head inlet valve is issued to liquid sucking-discharging purpose.At present, high-pressure pump plunger is pre-at locknut
Tight back-plunger center easily produces deflection, long-time in the case of plunger and part in stuffing-box there will be the phenomenon of eccentric wear.
Summary of the invention
It is an object of the invention to overcome the deficiency of above-mentioned technology, and a kind of high-pressure pump plunger is provided, prevent plunger from offseting.
The present invention for achieving the above object, by the following technical solutions:
A kind of high-pressure pump plunger, it is characterised in that: include plunger, power end, locknut, outer sleeve, semi-ring and pad, described pad
Sheet is placed in described power end slotted eye, and the front end of plunger coordinates with described pad, and described semi-ring is clamped on the end of described plunger,
With ladder platform in the inner circumference of described outer sleeve, described ladder platform coordinates with described semi-ring, and described locknut is threaded in institute
Stating on power end, plunger passes described locknut, is provided with disc spring between described locknut and described outer sleeve.
Preferably, it is provided with gasket ring between described disc spring and described locknut.
The invention has the beneficial effects as follows: relative to prior art, this device is reasonable in design, simple in construction, manufactures simplicity,
Low cost, uses Novel plunger connected mode alive, and plunger connects through disc spring pretension, locknut pretension back-plunger automatic capturing center
Deflection will not be produced, effectively solve plunger and the phenomenon of part eccentric wear in stuffing-box.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawings and preferred embodiment describe in detail the present invention detailed description of the invention.In description of the invention
In, it is to be understood that term " " center ", " longitudinally ", " laterally ", "front", "rear", "left", "right", " vertically ", " level ",
" push up ", " end " " interior ", the orientation of the instruction such as " outward " or position relationship are based on orientation shown in the drawings or position relationship, be only for
It is easy to describe the present invention and simplifying describe rather than instruction or the device of hint indication or element must have a specific side
Position, with specific azimuth configuration and operation, be therefore not considered as limiting the invention.
As it is shown in figure 1, a kind of high-pressure pump plunger, including plunger 1, power end 2, locknut 3, outer sleeve 4, semi-ring 5 and pad
Sheet 6, described pad is placed in described power end slotted eye 7, and the front end of plunger coordinates with described pad, and the front end of plunger is scheduled on described
On pad, described semi-ring is clamped on the end of described plunger, with ladder platform in the inner circumference of described outer sleeve, and described ladder platform
Coordinating with described semi-ring, outer sleeve is prevented from outer sleeve under the effect of semi-ring and is moved to the left, and described locknut is threaded in
On described power end, plunger passes described locknut, is provided with disc spring 8 between described locknut and described outer sleeve.Described disc spring with
Gasket ring 9 it is provided with between described locknut.This device is reasonable in design, simple in construction, manufactures simplicity, low cost, uses Novel plunger to live
Connected mode, plunger connects through disc spring pretension, and locknut pretension back-plunger automatic capturing center will not produce deflection, effectively solve
Plunger and the phenomenon of part eccentric wear in stuffing-box.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For Yuan, under the premise without departing from the principles of the invention, it is also possible to make some improvements and modifications, these improvements and modifications also should
It is considered as protection scope of the present invention.
