Method for protecting pump components

a technology for pump components and components, applied in the direction of machines/engines, liquid fuel engines, positive displacement liquid engines, etc., can solve the problems of rubbing of the plunger against the barrel, wear and tear of both of the components, and the variable pumping components are subject to wear and tear, so as to reduce friction and reduce friction-caused wear and tear

Benefits of technology

[0007] It is an object of the present invention to provide a method for reducing friction-caused wear and tear on pump components.
[0008] It is a further object of the present invention to provide a method for reducing friction-caused wear and tear on pump components through a method of coating such components with an improved protective coating material.
[0009] It is a still further object of the present invention to provide a method for reducing friction friction-caused wear and tear through a coating process, and to provide an improved ability to detect wearing away of coating material.

Problems solved by technology

During down-hole pumping operations, various pumping components are subject to wear and tear caused by repeated sliding or other movement that involves contact with another component.
For example, repeated movement of the ball relative to the seat (in each of the traveling valve and standing valve) causes wear to both of these components.
Rubbing of the plunger against the barrel, during up and down movement of the plunger relative to the barrel, is similarly wearing.
In general, pump components that are in sliding or other moving relationship to each other are subject to friction-caused wear and tear.

Embodiment Construction

[0010] Initially, some of the basic moving components of a fluid pumping system should be noted. Such components include a plunger, which travels within a barrel. The barrel is itself received within tubing. It further includes a traveling valve, which is opened and closed by movement of a ball that is received within a seat. (There term “ball” as used herein is intended to include valves.) Yet further, the apparatus will typically include a standing valve, which is similarly activated by movement of a ball / valve that is received within a seat.

[0011] According to one embodiment of the method of the present invention, it will be desired to coat pump components that are subject to friction-caused wear and tear with a protective coating. The protective coating should be amorphous carbon which, when applied, will have a Rockwell hardness in the range of 90 or greater. This will impart a ceramic like hardness to the applied surface. The thickness of the applied coating should be maintai...

Abstract

A method for protecting pump components by coating moving components with an amorphous carbon material. Components that preferably receive such coating include the plunger, barrel, traveling valve ball and seat, and standing valve ball and seat. Other components may also be coated. The coating thickness is preferably in the range of between about 0.0002″ and 0.030″. In one embodiment, at least two coating layers are applied, with the coating layers having different colored appearances so as to facilitate inspection for wearing away of the coating material.

Description

[0001] RELATED APPLICATION [0002] This is a continuation-in-part of Ser. No. 10 / 630,694, filed Jul. 30, 2003 in the name of the same inventor hereof, and to which priority is claimed.FIELD OF THE INVENTION [0003] The present invention relates generally to pumping systems and, more specifically, to a method for reducing wear and tear on pumping system components. BACKGROUND OF THE INVENTION [0004] During down-hole pumping operations, various pumping components are subject to wear and tear caused by repeated sliding or other movement that involves contact with another component. For example, repeated movement of the ball relative to the seat (in each of the traveling valve and standing valve) causes wear to both of these components. Rubbing of the plunger against the barrel, during up and down movement of the plunger relative to the barrel, is similarly wearing. In general, pump components that are in sliding or other moving relationship to each other are subject to friction-caused we...
