Abstract
The utility model discloses a ceramic plunger, which belongs to plunger pump engine fittings. The ceramic plunger comprises a metal plunger body, and is characterized in that the outer surface of the metal plunger body is coated with a ceramic layer or the metal plunger body is embedded in a ceramic tube. The ceramic plunger has the advantages of improving the wear resistance, prolonging the service life and reducing the production cost.
Description
Technical field
A kind of engine fittings of the utility model, particularly a kind of ceramic plunger.
Background technique
Existing plunger is to work under high temperature, high pressure, high-speed condition operating mode, owing to select metallic material for use, its material self character has determined that the plunger stability is poor, wear-resisting property is bad, there is short problem in working life, therefore long-time the use, its sealing effect is poor.
The model utility content
The purpose of this utility model is to overcome above-mentioned defective, and a kind of ceramic plunger is provided, and it improves the wear resistance of plunger, and prolong working life.
The purpose of this utility model is achieved through the following technical solutions: a kind of ceramic plunger, comprise the metal plunger body, and it is characterized in that: the surface-coated ceramic layer of said metal plunger body.
Described ceramic layer is an oxide ceramic layer, or the carbide ceramics layer, or the nitride ceramics layer.
A kind of ceramic plunger comprises the metal plunger body, it is characterized in that: said metal column cock body body is inlaid in the stoneware pipe.
Described stoneware pipe is the oxide ceramics pipe, or the carbide ceramics pipe, or the nitride ceramics pipe.
The beneficial effects of the utility model are: because at this external surface of metal plunger coated ceramic layer, or the metal plunger body is inlaid in the stoneware pipe, the wear-resisting property of plunger is improved, prolong working life, reduces production costs.
