Abstract
The utility model discloses a plunger of an oil well pump, which is characterized in that the surface of the excircle of the plunger of the oil well pump is coated with alloy coating with high corrosion resistance. The plunger has the characteristic of wear resistance and corrosion resistance, and can prolong the service life of the plunger pump, reduce the workload of the operation for inspecting the pump in an oil well and reduce the oil production cost.
Description
[technical field]
The utility model relates to a kind of oil well pump that is used for oil field operation, and what be specifically related to is a kind of plunger of oil well pump.
[background technique]
The field produces well of China about 80% uses the pumping production technology, generally use plunger oil-well pump in the pumping production technology, shortcoming maximum in the plunger oil-well pump application process is, the plunger of plunger pump up and down reciprocatingly is being easy to generate wearing and tearing and corrosion in the straight-line oil pumping process, thereby cause plunger pump short working life, the pump detection and workover workload is big.
[summary of the invention]
In view of the problem that present known technology exists, the technical problems to be solved in the utility model is to be to provide a kind of wear resistant corrosion resistant characteristics that have, and can increase plunger pump working life, reduces oil well pump detection and workover workload, reduces the oil pump plunger piston of cost for oil production.
For solving the problems of the technologies described above, the utility model takes following technological scheme to finish:
The plunger of oil well pump is characterized in that: the plunger outer round surface of described oil well pump is coated with the highly corrosion resistant alloy coat.Described highly corrosion resistant alloy coat adopts the Ni60A material.
The utility model is by being coated with the technological scheme of highly corrosion resistant alloy coat at the plunger outer round surface of oil well pump, not only improved the corrosion resistance of plunger greatly, simultaneously also improved the wear resistance of plunger, and solved wearing and tearing and corroded the vicious circle of mutually promoting.In sum, the utlity model has the wear resistant corrosion resistant characteristics, can increase plunger pump working life, reduce oil well pump detection and workover workload, reach the final purpose that reduces cost for oil production.
[description of drawings]
The utility model has following accompanying drawing:
Fig. 1 is the scheme of installation of the utility model in oil well pump
Fig. 2 is a structural representation of the present utility model
[embodiment]
Accompanying drawing has been represented the technical solution of the utility model and embodiment, further describes each relevant details and working principle thereof of embodiment below more in conjunction with the accompanying drawings.
As shown in Figure 1, 2, the plunger 1 of this oil well pump is actively installed in the cylindrical shell 3 of oil well pump, and plunger 1 outer round surface of described oil well pump is coated with highly corrosion resistant alloy coat 2, described highly corrosion resistant alloy coat 2 adopts the Ni60A material, and the Ni60A material has the characteristics of wear resistant corrosion resistant.Plunger 1 has increased the working life of plunger pump up and down reciprocatingly just being not easy to produce wearing and tearing and corrosion in the straight-line oil pumping process like this, has alleviated the pump detection and workover workload greatly, thereby reduces cost for oil production.
Claims (2)
1. the plunger of oil well pump, it is characterized in that: the plunger outer round surface of described oil well pump is coated with the highly corrosion resistant alloy coat.
2. the plunger of oil well pump as claimed in claim 1 is characterized in that: described highly corrosion resistant alloy coat employing Ni60A material.
