Abstract

The invention relates to a wear-resistant plunger pump which comprises a shell, a rack, a cylinder barrel, a plunger arranged in the cylinder barrel, a camshaft supported on the rack by a bearing, a driving device used for driving the camshaft, and an ejector rod, wherein one end of the ejector rod and the camshaft form tangency transmission fit, the other end of the ejector rod is connected to the plunger, and a cam surface in the circumferential direction of the camshaft is coated with a wear-resistant ceramic coating which is an Ni60+Ni/WC metal ceramic complex coating formed by laser cladding. A cam mechanism in the wear-resistant plunger pump is not easy to wear as the wear-resistant ceramic coating is coated; the use-cost is reduced.

Description

A kind of abrasion-proof plunger pump
Technical field
The present invention relates to a kind of plunger pump, be specifically related to a kind of abrasion-proof plunger pump.
Background technique
Plunger pump is an important device of hydraulic system.It relies on plunger to-and-fro motion in cylinder body, makes the volume of seal operation cavity volume change to realize oil suction, force feed.The advantages such as plunger pump has that rated pressure is high, compact structure, efficiency is high and Flow-rate adjustment is convenient, are widely used in the occasion that high pressure, large flow and flow need to regulate, in hydraulic press, engineering machinery and boats and ships.
During plunger pump work, plunger is done upper and lower to-and-fro motion, and plunger upper part space (pump chamber) produces degree of vacuum, thereby completes pump oil task.Plunger pump be take a plunger as principle introduction, on a plunger pump, there are two one-way valves, and opposite direction, when moving to a direction, plunger there is negative pressure in cylinder, at this moment an one-way valve opens liquid is inhaled in cylinder, when plunger moves to another direction, another one-way valve after liquid compression is opened, the liquid being inhaled in cylinder is discharged from.This working method has just formed continuous oil supply after motion continuously.
Have in the market the plunger pump driving by cam ejection pin mechanism, but easily there are the wearing and tearing of cam in this plunger pump.
Summary of the invention
The technical problem to be solved in the present invention is: propose the plunger pump that a kind of cam mechanism is difficult for wear and aging.
The present invention is that the technological scheme that solves the problems of the technologies described above proposition is: a kind of abrasion-proof plunger pump, comprise housing, frame, cylinder barrel, be located at plunger in described cylinder barrel, by bearing prop up the camshaft that is located in described frame, for driving the drive unit of described camshaft, also comprise that one end and described camshaft form tangent transmission and coordinate the other end to be connected to the item bar of described plunger, the camming surface surface that described camshaft week makes progress is coated with ceramic wear-resistant coating.
Further, described ceramic wear-resistant coating is the Ni60+Ni/wC cermet composite coating by laser melting coating.
The invention has the beneficial effects as follows:
The cam mechanism of plunger pump in the present invention is because scribble abrasion-proof ceramic coat, not easy to wear.Saved user cost.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, abrasion-proof plunger pump of the present invention is described further.
Fig. 1 is the structural representation of convexity wheel shaft of the present invention.
Embodiment
Embodiment
Shown in Fig. 1, abrasion-proof plunger pump in the present invention, comprise housing, frame, cylinder barrel, be located at plunger in described cylinder barrel, by bearing prop up the camshaft 1 that is located in described frame, for driving the drive unit of described camshaft 1, also comprise that one end and described camshaft 1 form tangent transmission and coordinate the other end to be connected to the item bar of described plunger, the camming surface surface that described camshaft makes progress for 1 week is coated with ceramic wear-resistant coating.
Described ceramic wear-resistant coating is the Ni60+Ni/WC cermet composite coating 2 by laser melting coating.
The cam mechanism of plunger pump in the present invention is because scribble abrasion-proof ceramic coat, not easy to wear.Saved user cost.
The above-described embodiment that is not limited to of the present invention, all employings are equal to replaces the technological scheme forming, and all drops in the protection domain of requirement of the present invention.

Claims (2)

1. an abrasion-proof plunger pump, comprise housing, frame, cylinder barrel, be located at plunger in described cylinder barrel, by bearing prop up the camshaft that is located in described frame, for driving the drive unit of described camshaft, it is characterized in that: also comprise that one end and described camshaft form tangent transmission and coordinate the other end to be connected to the push rod of described plunger, the camming surface surface that described camshaft week makes progress is coated with ceramic wear-resistant coating.
2. abrasion-proof plunger pump according to claim 1, is characterized in that: described ceramic wear-resistant coating is the Ni60+Ni/WC cermet composite coating by laser melting coating.
