Industry experts believe that the highlight of this award-winning product is a new breakthrough in original innovation. A new energy-saving system was proposed by the State Key Laboratory of Fluid Power Transmission and Control of Zhejiang University, the Second Institute of Oceanography of the State Oceanic Administration, and the Hangzhou University of Electronic Science and Technology “Switching hydraulic pressure source and deepwater pressure energy supply system based on this principleâ€. . Traditional multi-actuator hydraulic system oil supply pressure can not adapt to the actuator load, or can only adapt to the highest load pressure actuator, can not achieve low loss boost and buck, and switching power supply similar to the switching hydraulic power source can be the output of the hydraulic source The power is decomposed into each actuator and the input pressure or flow of the oil source is increased to achieve automatic adaptation of the actuator drive pressure and load to achieve the best energy-saving effect. The deep sea water pressure type energy supply system is a principle that uses sea water static pressure to provide power source for working equipment in a depth of several kilometers in the deep sea. In the sea trial, it has accumulated 831 W.h of electric energy. The project has won 6 national invention patents. In addition, the new electro-hydraulic proportional valve designed by Ningbo Huaye Machinery Manufacturing Co., Ltd. based on the new electro-hydraulic proportional control method - differential pressure feedback principle, and the electro-hydraulic proportional valve designed with the principle of pressure relief pressure feedback abroad In comparison, the number of parts is small, the structure is simple, and the process is good. It does not require special precision machining equipment and assembly environment. It has low cost and is easy to popularize and apply.
This time, there are many more integrated innovations in the outstanding new products, reflecting that integrated innovation has become the most effective way for technological innovation in the liquid airtight industry. Such as Guizhou Liyuan Hydraulic Co., Ltd.'s highly integrated piston type variable displacement hydraulic pump and motor, Zhenjiang Hydraulic Parts Factory Co., Ltd. combined dynamic load sensing full hydraulic steering system, Dawn Hydraulics Co., Ltd. TRF series suction return filter It is not only the integration of components, but the integration of the operating principles to be innovative, thereby improving the technical performance of products, to better meet the needs of the market, and has contributed to the improvement of the performance of construction machinery, agricultural machinery and other walking machinery.
The introduction of digestion and re-innovation is one of the major approaches for technological development in various countries, and it is also one of the ways for the rapid development of technology in the liquid gas-tight industry in China. In 2006, outstanding new products in the liquid airtight industry highlighted the status quo of the introduction, digestion, and innovation of the industry. Beijing Huade Hydraulic Industry Group Co., Ltd. DB2U10 ~ 30 ... -50B / two-stage electro-hydraulic pilot relief valve, 2FRE16-4X / two-way proportional speed control valve and HD-A7V160LVS constant power load sensing variable displacement pump, The seamless steel tube rolling mandrel graphite lubrication system declared by Bukoma Accumulator (Tianjin) Co., Ltd. has developed new products that meet or exceed the technological level of similar foreign products on the basis of introduction and digestion. On the basis of the introduction and digestion, some companies have also expanded their product specifications and models to fill in the gaps so that users can have more opportunities to choose domestic products, such as the HD-A7V500EP electronic control proportional variable of Beijing Huade Hydraulic Industry Group Co., Ltd. The pump is currently the largest piston variable pump in domestic displacement, 2.5CY14-1B swashplate manual variable displacement axial piston pump and 400CY14-1B axial piston pump produced by Qidong High Pressure Pump Co., Ltd., the displacement series includes the smallest 2.5mL/r to a maximum of 400mL/r.
These outstanding new products have contributed to the construction of key national projects, such as the Angang 2150 hot strip line hydraulic system and the 1700 hot strip line hydraulic system provided by Yuci Oil Refinery Hydraulic Co., Ltd., which are based on electro-hydraulic proportional control technology. The large-scale complete hydraulic system designed with computer technology as its core fully demonstrates that Chinese enterprises have the ability to undertake and complete the country's key engineering construction tasks while tracking international advanced standards, and enhance the competitiveness of China's equipment manufacturing industry in related fields.
The environmental protection and energy-saving products in this batch of outstanding new products account for a large proportion, indicating that the company’s concern for environmental protection, energy conservation, and sustainable development is increasing. These products not only improve the technical performance, but also have obvious effects in reducing noise, such as the CBHC-F** high-pressure low-noise hydraulic gear pump developed by Hefei Changyuan Hydraulic Parts Co., Ltd., and the new low noise of HY125 from Jiangsu Hengyuan Hydraulic Co., Ltd. Swash plate type axial piston pumps, CSSC Chongqing Hydraulic Electromechanical Co., Ltd. GP series gear pumps, etc., adopt new structures, new materials and new processes, reducing the noise by 4~5dB(A). Dalian Hydraulic Machinery Co., Ltd.'s variable-speed hydraulic couplings are widely used in power generation equipment, large-scale water pumps and other fields, and have obvious energy-saving effects.
Two-and-a-half butt welding technology for 25VQH, 35VQH, 45VQH high-pressure vane pumps declared by Jincheng Group Hydraulic Engineering Division, high-performance silicone sealant developed by Guangzhou Institute of Machinery Science, Anhui Ningguo Zhongding Sealing Parts Co., Ltd. It is not difficult to see that in the products and technologies of high-speed reciprocating oil seal material formulations used in the automotive shock absorbers in the North, the liquid airtight industry is making greater progress in adopting new processes, new materials, and new structures.
The experts concluded that these new products have set an example for the entire industry in terms of independent innovation, improving product performance, lowering production costs, expanding the application fields, and enhancing the competitiveness of enterprises. They have made a model for the development of mainframes and the construction of national key projects. Contributed.
In order to summarize the experience of the liquid airtight industry in technological innovation, promote the development of new products, promote brand-name product strategy, and improve the competitiveness of China's liquid airtight products in domestic and foreign markets, the China Hydraulic & Pneumatic Sealing Industry Association recently organized the 2006 liquid In the selection of outstanding new products in the airtight industry, a total of 68 products from 34 companies participated in the selection, and the final 52 products from 28 companies won awards. Among them, there are 7 first prizes, 14 second prizes, and 31 third prizes. These award-winning products all have independent intellectual property rights, and most of the products fill domestic gaps. The technical performance indicators of a considerable number of products have reached or approached the international advanced level, and the market prospects are broad.
