"It is estimated that by 2020, the domestic vacuum pump market will reach more than 10 million units, and it is accelerating. The automotive vacuum pump has become an indispensable key component." Director of Jiangsu Meihua Machinery Co., Ltd. (abbreviated as "Meihua Machinery") Weimei Wei is full of confidence in the future market prospects of vacuum pumps. It is understood that automotive vacuum pumps are mainly used in automotive brake systems to provide a vacuum source for vacuum boosters in automotive brake systems, reducing pedal resistance and thereby reducing braking distance. When passenger cars and light commercial vehicles are equipped with engines that do not have a stable vacuum source, vacuum pumps are required to provide vacuum sources for vacuum boosters, such as diesel engines, turbocharged and direct injection gasoline engines, hybrid power and electric power. An engine that does not produce a stable vacuum source. At present, vacuum pumps on the market can be divided into mechanical vacuum pumps and electronic vacuum pumps according to driving methods. The mechanical vacuum pump has the advantages of simple structure and low cost, but as the technology continues to advance, the electronic vacuum pump has also become a product vigorously developed by various vacuum pump companies. Industry sources told reporters that the electronic vacuum pump has a higher speed and is directly driven by a direct current motor. The pumping speed is not affected by engine operating conditions, and it can be started and paused intelligently, thus greatly reducing the actual operating time of the pump. “In recent years, electronic vacuum pumps have been widely used in many small petrol engines. Vacuum pumps are gradually transitioning from the previous mechanical control to motor control to reduce the energy consumption requirements and potential pollution of the engine, while also achieving more accurate "Program control." Wang Xiaolong, technical director of Meihua Machinery, said, "The mechanical vacuum pump will only be kept on commercial vehicles and a small portion of passenger vehicles. The electronic vacuum pump will become the standard configuration for most passenger vehicles." Experts predict that China’s vehicle ownership will reach 250 million by 2020. Such a huge automobile market is bound to bring about the vigorous development of the auto parts market. As an indispensable automobile vacuum pump in brakes, it will surely usher in the “spring†of development. However, most of the current automotive vacuum pump market is occupied by foreign companies such as WABCO, Hella, Bosch and China. China's independent enterprises started relatively late in this field, and they have a large gap with foreign companies in terms of materials, design and test verification, manufacturing, processing, assembly, etc., and they have less market share. How to win a place in the future automotive vacuum pump market? This has become a problem faced and urgently needed to be solved by the entire auto parts industry. “Domestic companies need to increase investment and accumulate experience in basic research, system design calculations and applications, and test verification. At the same time, domestic companies should improve their manufacturing, processing, and assembly capabilities to ensure product stability and consistency. It may have a place in the competition with multinational companies," said Yan Jianzhi, deputy secretary-general of the China Association of Automotive Engineers. At the same time, automotive vacuum pump companies are also carrying out technological transformation and product upgrades. Jilin Dongguang Aowei Automobile Brake System Co., Ltd. told reporters that the company is cooperating with Dongfeng, Beiqi New Energy and other automakers to conduct research and development in order to make the products meet the market demand; and with the development of automotive electronics technology, the future also Will do research and development of related products. Wei Meifang said that at present, Meihua Machinery has completed the virtual analysis of electronic pumps and trial production of prototypes, and the production line has also been upgraded to a smart assembly line, which is moving toward smart and energy-saving electrification.
