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 cylinder roller bearing in the automotive industry
The
cylinder roller 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 cylinder roller 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 cylinder roller 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
cylinder roller 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, cylinder roller 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. If you are looking for

The
impact of new bearings on cylinder roller 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
cylinder roller 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 cylinder roller bearing can only be solved by using non-conductive
ceramic balls, which will improve the technical level of the cylinder roller
bearing for household appliances.
The
impact of new bearings on cylinder roller 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 cylinder roller 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 cylinder roller
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
cylinder roller 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 cylinder roller bearing, the
development of various industries has increasingly higher requirements on the
accuracy, performance, life and reliability of cylinder roller 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
cylinder roller bearing products have a broad market prospect.
