Abstract
The forceps chromium alloy valve body place is one kind of oil field, the geological well drilling with the sludge pump fitting, it has overcome the present technology existence shortcoming, its manufacture craft is: Berylliuim copper alloy fierce on valve body valve seat, the degree of hardness is Hrc59-62, grinds. Product nature stable, is durable prolonged.
Description
One, technical field: the present invention relates to a kind of oil field welldrilling slurry pump accessory, especially Nickel-chromium alloy valve body and valve seat.
Two, background technique: at present, the easily damaged parts that domestic petroleum, geological drilling use with slurry pump: valve body, valve seat, general working life is all about 100～200 hours.Every replacing once all will stop to bore several hours.Both waste the rig operating time, influenced drill footage again.Influence overall drilling efficiency.
Three, summary of the invention: the purpose of this invention is to provide Nickel-chromium alloy valve body and valve seat, overcome the shortcoming that present technology exists, the object of the present invention is achieved like this, and its manufacturing process is: nichrome is welded on the valve body and valve seat, and hardness is the HRC59-62 degree; Polishing then, roughness is 0.8～0.4.Product property is stable, and is durable in use.
Four, description of drawings: do not have.
Five, embodiment: the manufacturing process of Nickel-chromium alloy valve body and valve seat is: nichrome is welded on the valve body and valve seat, and hardness is the HRC59-62 degree; Polishing, roughness is 0.8-0.4.
Claims (1)
1. Nickel-chromium alloy valve body and valve seat, it is characterized in that: manufacturing process is: nichrome is welded on the valve body and valve seat, and hardness is the HRC59-62 degree; Polishing, roughness is 0.8-0.4.
