Embodiment Construction

[0014] Below in conjunction with accompanying drawing, content of the invention will be further described:

[0015] refer to figure 1 As shown, a two-way protection lubricating and wear-resistant coupling includes coating a lubricating and wear-resistant agent on the surface of the sucker rod coupling 1 through a surface strengthening treatment process to form a lubricating and wear-resistant agent layer 2, and the lubricating and wear-resistant agent layer The thickness of 2 is less than 0.5mm. The lubricating and wear-resistant agent includes anti-corrosion agent, MoS2 and high-efficiency adhesive. The weight percentage of the anti-corrosion agent in the lubricating and wear-resistant coating agent ranges from 10% to 13%. The weight percentage of the MoS2 in the lubricating and wear-resistant coating agent ranges from 20% to 25%, and the weight percentage of the high-efficiency binder in the lubricating and wear-resistant coating agent ranges from 15% to 20%. Described pres...

Abstract

A bidirectional protection lubricating wear-resistant coupling comprises a lubricating wear-resistant agent layer formed by coating lubricating wear-resistant agent on the surface of a sucker-rod coupling through the surface reinforcing treatment process. The thickness of the lubricating wear-resistant agent layer is less than 0.5mm. Defects conventionally existing in the prior art that hardness is low, strength is low, wear resistance is low, corrosion resistance is low, scratch resistance is low, heat resistance is low, friction coefficient is high, self-lubrication and oxidation resistance cannot be completed, impact resistance is low, high temperature stability is poor, and service life is short are avoided effectively.

Description

technical field [0001] The invention relates to the technical field of a two-way protection wear-resistant device, in particular to a two-way protection lubricating and wear-resistant coupling. Background technique [0002] The existing sucker rod couplings are often not lubricated and wear-resistant, which leads to the common problems of low hardness, low strength, low wear resistance, low corrosion resistance, low scratch resistance, and poor temperature resistance. , High friction coefficient, no self-lubricating anti-oxidation, low impact resistance, poor high temperature stability, and short service life. [0003] The sucker rod coupling of the present invention is mainly lubricated and wear-resistant. This process mainly involves wear-resistant lubricants. The lubricated wear-resistant agents include anti-corrosion agents, MoS2 and high-efficiency adhesives. MoS2 black solid powder with metallic luster. The melting point is 1185°C, the density is 4.80g / cm3 (14°C), an...
