Petrochemical bearing forgings are widely used in various machinery and equipment in the petrochemical industry, and their selection and design directly affect the performance, life and safety of equipment. This paper will discuss the selection and design guidance of petrochemical bearing forgings to provide reference for enterprises.
Selection guide
Determine the use scenario: According to the use scenario and working condition of the equipment, select the appropriate petrochemical bearing forgings. For example, for high temperature, high pressure, corrosive environment, should choose high temperature, corrosion resistance, high strength bearing forgings.
Determine the load conditions: according to the load conditions borne by the equipment, select the petrochemical bearing forgings that can meet the design requirements. For example, for equipment that withstands heavy loads, bearing forgings with high load bearing capacity should be selected.
Determine the speed and accuracy requirements: according to the speed and accuracy requirements of the equipment, select the appropriate petrochemical bearing forgings. For high-speed and high-precision equipment, bearing forgings with high rotation accuracy and low friction coefficient should be selected.
Determine the life and reliability requirements: according to the service life and reliability requirements of the equipment, select the appropriate petrochemical bearing forgings. For equipment that requires long operation and high reliability, bearing forgings with long life and high reliability should be selected.
Determine compatibility and interchangeability requirements: Select the appropriate petrochemical bearing forgings according to the compatibility and interchangeability requirements of the equipment. For equipment that needs to be compatible or interchangeable with existing equipment, bearing forgings that meet the relevant standards should be selected.
Design guidance
Material selection: According to the use scenario and working conditions, select the appropriate material to manufacture petrochemical bearing forgings. Commonly used materials include high quality carbon steel, alloy steel, stainless steel and so on.
Structure design: According to the use requirements and working conditions, reasonable design of the structure of petrochemical bearing forgings. For example, the structural form of the bearing seat and the journal is reasonably designed to ensure the reliability of installation and use.
Heat treatment and surface treatment: According to the use needs and working conditions, the petrochemical bearing forgings for appropriate heat treatment and surface treatment. For example, by quenching, tempering and other processes to improve the hardness and wear resistance of materials; The corrosion resistance and wear resistance of the material are improved by chromium plating, spraying and other processes.
Lubrication design: Reasonable design of the lubrication system to ensure that the petrochemical bearing forgings are fully lubricated during use. For example, through the design of the lubricating oil passage, ensure that the bearing seat and the journal surface lubrication is uniform and sufficient.
Check and verification: Check and verify the designed petrochemical bearing forgings to ensure that they meet the requirements and safety performance. For example, stress analysis and fatigue life calculations are performed to verify the reliability of the design.
Documentation and archiving: Prepare complete technical documents, including design drawings, bills of materials, and process flows, for subsequent maintenance and use. At the same time, the document is archived and saved for reference and use.
The selection and design of petrochemical bearing forgings is one of the important links in petrochemical industry. In practical applications, enterprises should conduct reasonable selection and design according to the use scenario, working conditions and other factors to ensure that the petrochemical bearing forgings can meet the performance, life and safety requirements of the equipment. At the same time, strengthen technology research and development and personnel training, improve the design ability and technical level of enterprises, and provide strong support for the sustainable development of the petrochemical industry.
