The test results of the imported bearings show that the bearing body material is 35CrMo, and the bearing lining material is tin-bismuth bearing alloy. 35CrMo material is characterized by high durability and Confucian strength at high temperature, good low temperature toughness, working temperature up to 500 ° C, low temperature up to -110 ° C, and high static strength, impact toughness and higher The fatigue strength and the quenching deformation are small. The tin-bismuth bearing alloy material is characterized by good compliance, bite resistance and corrosion resistance. The main parameters are: =25MPa, In addition, in order to make the bearing alloy have better wear resistance and corrosion resistance, the content of niobium was increased from 10.96% to 11.36% in the development. At the same time, in order to ensure the quality of the bearing and the lining, the bearing lining is made of centrifugally cast bearing alloy, which improves the casting quality. The bearing body is ultrasonically flawed and the lining is magnetic particle inspection. The successful development of the domestically produced bearings solved the shortage of imported pump parts and achieved great economic and social benefits. Save money on buying imported bearings. The price of imported bearings is 70,000 yuan per pair, while the price of domestic bearings is 22,000 yuan, which is more than 2 times, which can directly save more than 60% of the cost of purchasing spare parts. Due to the convenience of domestic manufacturing, it can be supplied at any time, reducing inventory pressure and improving the utilization of funds. The successful development of domestically produced bearings has solved the key problems for the development of new products in the domestic electromechanical industry. Equipment of the same size can reduce cooling facilities, reduce system complexity, and reduce manufacturing and maintenance costs in future designs. The product can also be used in similar rotary equipment.
