Problems solved by technology

However, due to many reasons such as high water content, the sealing material of the original oil pumping wellhead polished rod has poor lubrication conditions and low performance, resulting in aggravated wear of the sealing material of the pumping unit, and serious water and oil leakage
If the sealing packing is replaced repeatedly, it will not only increase the labor intensity of the workers, but also cause environmental pollution, and the most serious problem is to affect the output of the pumping well.

Abstract

The present invention belongs to a sealing tool, particularly a packing production method. The raw materials required by the packing production method comprise 10-12 g of a fluorine glue, 7-9 g of a butadiene-acrylonitrile rubber, 0.2-0.8 g of graphite, 0.1-0.6 g of sulfur powder, 0.1-0.3 g of an accelerator M, 0.1-0.3 g of an accelerator CZ, 0.1-0.3 g of an accelerator TT, 2-7 g of high wear resistance carbon black, 0.1-0.5 g of stearic acid, 0.2-1 g of zinc oxide, 2-4 g of dibutyl ester, and 3-5 g of light calcium carbonate. The produced packing of the present invention has characteristics of high elasticity, strong acid resistance, strong alkali resistance, and strong wear resistance. In addition, characteristics of simple production manufacturing and low production cost are provided, and the produced packing is suitable for promotion and application in the related fields.

Description

Technical field [0001] The invention belongs to a sealing appliance, in particular to a manufacturing method of packing. Background technique [0002] At present, in oil exploitation, the polished sucker rod reciprocates up and down in the wellhead, and the seal between the two is mainly realized by a sealer equipped with a packing inside. However, due to many reasons such as high water content, the original pumping wellhead polished rod sealing material has poor lubrication conditions and low functions, resulting in increased wear of the sealing material of the pumping unit, and serious water and oil leakage. If the sealing packing is replaced repeatedly, it will not only increase the labor intensity of workers, but also cause environmental pollution problems, the most serious of which is affecting the output of pumping wells. Summary of the invention [0003] The purpose of the present invention is to solve the deficiencies in the prior art and provide a method for making packi...
