Successfully developed new composite bearing
Recently, the China Machinery Industry Federation organized a review meeting in Harbin for the "Hualong No. 1 Nuclear Power Unit Reactor Coolant Pump Thrust Bearing" independently developed by Harbin Electric Power Equipment Co., Ltd. of Harbin Electric Group. At the review meeting, the project successfully passed the review with unique domestic and internationally leading review results, marking that another independently developed nuclear power technology by my country\'s equipment manufacturing enterprises will lead the development of new international composite bearings.
An expert group composed of 13 experts including Yu Junchong, Academician of the Chinese Academy of Engineering, Jian Xi Gao, etc., unanimously agreed that the new composite material bearing is superior to the babbitt alloy thrust bearing. It has completely independent intellectual property rights, filling the domestic gap and reaching the international leading position. Level. After supplementing relevant analysis and test verification, it can be promoted and applied in newly-built units.
Experts at the meeting said that the new type of composite thrust bearing of polyarylethersulfone ketone resin (PPESK) resin-based composite material developed by Harbin Electric Equipment with independent intellectual property rights has advanced design methods, reasonable structure, excellent manufacturing process and material selection, and performance indicators meet the technical requirements. Technical requirements including all working conditions including the non-top oil idle shutdown (SBO working condition). The full-size thrust bearing has undergone 375-hour full-flow operation test and 53 start-stop (including 2 stops without top oil), and the results meet the requirements of the technical specification and test program; the thrust pad material has undergone 2184 hours of high-temperature oil immersion test, The material performance is stable; at the same time, the 300MW nuclear power main pump thrust bearing made of the same material and process has completed 2012 hours of high-load operation and 206 non-top oil start-stop tests on the bearing test bench, and various performance indicators meet the technical requirements.
The Secretary of the Party Committee and Chairman of the Harbin Electric Group Company Szef said that the Harbin Electric Group has done some work in promoting the development of my country\'s nuclear power industry and has achieved certain results, but there is still a long way to go on the road to research and development in the future. To go, Harbin Electric Group will keep in mind its mission and responsibilities, actively implement the new development concept, vigorously implement the innovation-driven development strategy, move forward, and play a major role in accelerating the construction of an innovative country.
The impact of new bearings on 32221 bearing in the automotive industry
The 32221 bearing is mainly used to complement the host industry, including automobiles, home appliances, medical equipment and other industries. The development of related industries will drive the demand of the industry. China auto market has maintained a trend of rapid growth in recent years. Considering factors such as car ownership, per capita income, and per capita car ownership, cars are still in the incremental market and have not been transferred to the stock market. According to the "2015-2020 China Bearing Manufacturing Industry Production and Sales Demand Forecast and Transformation and Upgrade Analysis Report" released by the Foresight Industry Research Institute, the high growth rate of the automotive industry will continue for a period of time, and the future growth rate will not be less than 15%.
With the process of miniaturization and electrification of automobiles, the corresponding component products are constantly increasing. Therefore, the automotive-related parts market will continue to expand in the future. The development of automotive bearings will focus on safety, improving efficiency and reducing harmful substances. Automobile radiator cooling fan motor, wiper motor, exhaust gas recirculation system (EGR) valve frame and anti-lock brake system (ABS) represented by oil pump motors and their application systems are the main application areas of miniature bearings.
In particular, the 32221 bearing for ABS was only used for high-end cars in the 1980s. After that, it was used as an important product for safety measures in the direction of miniaturization and popularization, and its use has been continuously expanded since the mid-1990s. The automobile spindle developed at present is developing towards multi-function and safety. It not only uses the 32221 bearing to control the brake intermittently, but also links with the sensor that monitors the driving situation, and transmits different braking forces to the front, rear, left, and right wheels. Control safe driving as a whole. The future development trend of miniature bearings. This system is an ABS upgrade system. Different manufacturers have different 32221 bearing such as ESC, EPS, VSC and so on.
The development of ABS system is a typical example of the development of automobile-related products. In the future, 32221 bearing will derive many new application products with increasing requirements for safety and environmental protection. The imported bearing market aims at hybrid vehicles and electric vehicles to try to create new types of car-related products. In this development, the field of miniature bearings will continue to expand, and its precision will continue to improve. With the continuous development of China\'s automobile industry, there is huge room for domestic enterprises to develop.

The impact of new bearings on 32221 bearing in the home appliance industry
The market scale of China household appliance industry has been expanding year by year, and the growth rate has declined in the past two years. The Institute of Foresight Industry predicts that the market scale of China household appliance industry will continue to expand year by year.
The 32221 bearing for home appliances represent motor bearings for vacuum cleaners and air conditioners, mainly motors with an outer diameter of 22mm. The characteristic of the vacuum cleaner is that the rotation speed of the motor is as high as 40,000 rpm/min, and the motor of 100,000 rpm/min has also been used in vacuum cleaners sold in large quantities in the market. Air conditioners are equipment used indoors for a long time and have high requirements for low noise. The current problem is that the electrical corrosion caused by the electrical connection between the inner and outer rings of the 32221 bearing can only be solved by using non-conductive ceramic balls, which will improve the technical level of the 32221 bearing for household appliances.
The impact of new bearings on 32221 bearing in the medical industry
In recent years, the market scale of China medical device industry has maintained rapid growth. The Prospective Industry Research Institute predicts that China medical device industry will maintain a growth rate of more than 20%.
In medical equipment, the use of 32221 bearing also involves many aspects, mainly used for blood pumps for artificial dialysis, drug injection pumps, and air pumps for ventilators. These devices are used on the pillow side of the hospital bed, so they must be treated with low noise.
An extreme example is the dental drill used by the dentist. The drill bit is 400,000 to 500,000 revolutions per minute, which is difficult for the doctor to bear under the stimulation of the high pitch. A major issue in the name of medical device products is the corrosion resistance of the 32221 bearing to chemicals and acids. This is an issue that cannot be separated from bearing materials.
From the future development trend of bearings in the above application fields, the 32221 bearing are mainly developed in the direction of precision and bass, so the future development direction is the name of precision products. In view of the wide application of precision 32221 bearing, the development of various industries has increasingly higher requirements on the accuracy, performance, life and reliability of 32221 bearing, and the number of requirements is also increasing. In recent years, China domestic machine tool industry and automobile industry have developed rapidly. In order to meet the needs of product upgrading and replace imports, China precision 32221 bearing products have a broad market prospect.
