High temperature corrosion and wear resistant technical process for oil-well pump cylinder plunger valve

Abstract

The present invention provides alloy plating solution and corresponding treating process for producing oil well pump capable of resisting high temperature corrosion and high temperature wear, and with low cost and low power consumption. The alloy plating solution is compounded through dissolving nickel sulfate, amino acetic acid, amino borane, graphite fluoride, boric acid, sodium saccharin, lead ion, ammonia water and sodium hydroxide in the weight ratio of 3 to 2.5 to 0.45 to 0.6 to 3 to 0.3 to 0.003 to 0.35 to 0.15 in pure water of 90 weight portions. During plating, the alloy plating solution is heated to 40-60 deg.c, and the plating time is determined based on thickness to be plated.

Description

(1) Technical field: [0001] The invention belongs to the field of oil extraction equipment manufacturing, and relates to a catalytic alloy plating solution and a surface treatment technology for oil pump barrel plunger pump valves of special equipment for mechanical oil extraction that are resistant to high temperature corrosion and high temperature wear. (two) background technology: [0002] The oil pump is an important and irreplaceable special equipment for mechanical oil recovery in oil exploitation. More than 80% of the production wells in major domestic oil fields use rod pumping equipment, ranking first among mechanical oil recovery wells, accounting for 75% of the national oil production. %. The main components of the oil well pump are composed of pump barrel, plunger and pump valve. In crude oil extraction, oil wells, oil-gas mixing wells, and water injection wells all contain gas and sand; various media are corroded; In addition to high requirements on structure,...
