Abstract

The invention relates to the technical field of cylinder liner processing, in particular to a method for preparing a mud pump cylinder liner. Step 1: Roughly process the cylinder liner liner; Step 2: Perform heat treatment on the rough-processed cylinder liner liner; Step 3 1. Process and polish the cylinder liner liner after the magnetic field heat treatment in step 2; step 4, heat the cylinder liner coat to 400-500°C and install and machine the polished cylinder liner liner to obtain the mud pump cylinder liner. The surface hardness and wear resistance of the liner prepared by the present invention are improved, and the hardness of the bimetallic cylinder liner is increased from the existing 58-61HRC to 63-64HRC. At the same time, the toughness and other mechanical properties of the cylinder liner prepared by the present invention are improved. .

Description

technical field

[0001] The invention relates to the technical field of cylinder liner processing, in particular to a preparation method of a mud pump cylinder liner. Background technique

[0002] With the development of the economy and the improvement of living standards, the consumption of energy is also increasing. In the foreseeable future, emerging energy sources cannot replace fossil fuels such as coal, oil, and natural gas, occupying a dominant position in energy consumption. With the increasing difficulty of oil and natural gas extraction, the increasing drilling depth, and the increasingly complex drilling conditions, higher requirements are placed on the equipment used for oil and natural gas extraction. Cylinder liner is one of the main wearing parts of mud pump equipment in the field of oil drilling and production. Its service life directly affects the drilling speed of oilfield development and the safety of drilling construction.
