Abstract
The invention discloses a novel high abrasion proof plunger, and relates to the technology of a plunger pump for an oil well of an oil field. The novel high abrasion proof plunger is formed by adding metal tungsten to an original nickel-base alloy layer. In the concrete implementation, a tungsten powder is added to an original nickel-base alloy powder, and the tungsten powder accounts for 2-50% of the original nickel-base alloy powder; then the mixture of the tungsten powder and the nickel-base alloy powder is sprayed and welded on the surface of the plunger to form a new alloy layer; the particle size of the tungsten powder is 100-400 meshes. The plunger disclosed by the invention has the significance that because the novel alloy layer is added on the surface of the plunger, the abrasion resistant property of the plunger is substantially improved, the service life of a product is prolonged, and the cost is reduced.
Description
Technical field: the present invention relates to oilfield plunger pump technique, especially a kind of novel high abrasion plunger.
Background technique: at present, the plunger of plunger pump for doing work, make at the surface spraying weld hard Co-based alloy powder of structural steel, due to plunger bear high pressure at work, high mill power of rubbing is poor, nickel base alloy layer abrasion resistance is not enough, cause the plunger effective date operating time short, cause changing frequently, artificial, high material consumption.
Summary of the invention: the object of this invention is to provide a kind of novel high abrasion plunger with high abrasion degree, which overcome the shortcoming of current technology, the object of the present invention is achieved like this, it adds tungsten in original nickel base alloy layer, in concrete enforcement, in original nickel-base alloy powder, add tungsten powder, tungsten powder accounts for the 2-50% of original nickel-base alloy powder, then surfacing is to plunger surface, forms the alloy-layer that one deck is new; The granularity of tungsten powder is 100-400 order.
Meaning of the present invention is: owing to the addition of the novel alloy-layer of one deck at plunger surface, increased substantially the antiwear property of plunger, extended the working life of product; Save expense.
Embodiment: embodiment 1, the present invention add tungsten in original nickel base alloy layer.
In embodiment 2, concrete enforcement, in original nickel-base alloy powder, add tungsten powder, tungsten powder accounts for the 1-50% of original nickel-base alloy powder, and then surfacing is to plunger surface, forms the alloy-layer that one deck is new.
The granularity of embodiment 3, tungsten powder is 100-400 order.
Claims (3)
1. a novel high abrasion plunger, is characterized in that: it adds tungsten in original nickel base alloy layer.
2. a kind of novel high abrasion plunger according to claim 1, it is characterized in that: in original nickel-base alloy powder, add tungsten powder, tungsten powder accounts for the 1-50% of original nickel-base alloy powder, and then surfacing is to plunger surface, forms the alloy-layer that one deck is new.
3. a kind of novel high abrasion plunger according to claim 1, is characterized in that: the granularity of tungsten powder is 100-400 order.
