Petrochemical Machinery "3300 plunger pump bearing localization" sample passed the durability bench test

recently, the bearing sample of the special project of petrochemical machinery "3300 plunger pump bearing localization" passed the 80 hour durability bench test in the factory, and no quality problems were found after disassembly, which marks the important phased progress of the project. 330 draw fatigue life curve (S-N curve); Equipped with various special fixtures, type 0 plunger pump is the core component of petrochemical machinery 2500 and 3000 fracturing trucks. Recently, the industrial chain has been continuously extended with

. The bearing samples of the special project "localization of 3300 plunger pump bearings" of petrochemical machinery have passed the 80 hour durability bench test in the factory, and no quality problems have been found after disassembly, which indicates that the project has made important phased progress

3300 plunger pump is the core component of 2500 and 3000 fracturing trucks of petrochemical machinery. For a long time, the high-end bearings used in this type of pump assembly have been imported

in order to master the core technology and not get stuck, petrochemical machinery has carried out special research on the localization of 3300 plunger pump bearings since this year. All departments and units of design, research and development, quality control, production and manufacturing, measurement and testing, etc. work together to carefully prepare the quality control plan of localized bearings, put forward clear requirements for product quality traceability, key points of quality control, assurance method of manufacturing process, product acceptance conditions and completion data, and arrange special personnel from blank, heat treatment, machining, magnetic particle flaw detection of parts, ultrasonic flaw detection, product measurement and inspection The whole process of parts cleaning and assembly, marking, inspection record sheet, etc. was supervised to ensure the smooth progress of the project

in the next step, petrochemical machinery will carefully analyze the preliminary test results, make every effort to make preparations for industrial tests under different working conditions and use them according to their regulations, and promote the localization of 3300 plunger pump bearings to speed up and steadily implement
