Abstract
Friction of plunger pump valve plate is vice, valve plate friction vice president becomes including cylinder body, transition layer, wearing layer and valve plate, the cylinder body outer wall is provided with the transition layer, the plane valving surface is provided with the wearing layer, the wearing layer surface is provided with the zirconia ceramic layer, transition layer and wearing layer are closely laminated. The thickness on zirconia ceramic layer is 0.3 -0.7mm. The utility model has the advantages that resistance to wear, it is corrosion -resistant, longe -lived.
Description
Technical field
This utility model belongs to valve plate of plunger pump, is specially valve plate of plunger pump friction pair.
Background technology
Plunger displacement pump is widely used in engineering truck, lathe, large-scale production line, is one of most important actuator parts, and its disabling portion is mainly friction pair. Existing valve plate of plunger pump surface of friction pair material is divided into three kinds substantially, and one is acid bronze alloy, and two is babbit, and three is chrome-faced. Shortcoming is easy to wear, and the life-span is short, contaminated environment.
Utility model content
The purpose of this utility model is in that to provide valve plate of plunger pump friction pair, solves the shortcoming in background technology.
This utility model realizes by the following technical solutions:
Valve plate of plunger pump friction pair, valve plate friction pair assembly includes cylinder body, transition zone, wearing layer and valve plate, described outer wall of cylinder block is provided with transition zone, described plane valving surface is provided with wearing layer, described wearing layer surface configuration has zirconia ceramic layer, and described transition zone and wearing layer fit tightly.
In this utility model, the thickness of described zirconia ceramic layer is 0.3-0.7mm.
Beneficial effect: the utility model has the advantages that and resistance to wear, corrosion-resistant, the life-span is long.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is partial enlarged drawing of the present utility model.
Detailed description of the invention
For the technological means making this utility model realize, creation characteristic, reach purpose and effect and be easy to understand, below in conjunction with being specifically illustrating, this utility model is expanded on further.
Referring to Fig. 1, Fig. 2, the assembly structure chart of valve plate of plunger pump friction pair, the partial enlarged drawing of valve plate of plunger pump friction pair, valve plate of plunger pump friction pair, valve plate friction pair assembly 10 includes cylinder body 1, transition zone 2, wearing layer 3 and valve plate 4, described cylinder body 1 outer wall is provided with transition zone 2, described valve plate 4 surface configuration has wearing layer 3, described wearing layer 3 surface configuration has zirconia ceramic layer, described transition zone 2 and wearing layer 3 fit tightly, and the thickness of described zirconia ceramic layer is 0.3-0.7mm.
Of the present utility model ultimate principle and principal character and of the present utility model advantage have more than been shown and described, skilled person will appreciate that of the industry, this utility model is not restricted to the described embodiments, described in above-described embodiment and description is that principle of the present utility model is described, under the premise without departing from this utility model spirit and scope, this utility model also has various changes and modifications, these changes and improvements both fall within the scope of claimed this utility model, this utility model claims scope and is defined by appending claims and equivalent thereof.
