Manifold and valve member with the combination of research

According to incomplete statistics, in 2011 China's fluid sealing industry above designated size industrial output value of 77.271 billion yuan enterprises, an increase of 21%, of which the hydraulic industry completed 43.62 billion yuan, an increase of 18.47%; pneumatic industry completed 15.046 billion yuan, an increase of 29.60%; sealing industry completed 18.605 billion yuan, an increase of 23.95%. fluid airtight industry 125 key enterprises in 64 hydraulic industry, hydraulic industry 6, pneumatic industry 40, 15 sealing industry, economic efficiency index was 233.56, 226.44 over the same period last year. these key enterprises of the industrial output value of 33.424 billion yuan, an increase of 12.94 percent, of which the output value of 14.171 billion yuan hydraulic enterprises, an increase of 7.72%; hydraulic enterprise value of 533 million yuan, down 4.77%; pneumatic enterprise value of 8.639 billion yuan, an increase of 25.12%; sealing enterprise value of 7.32 billion yuan, an increase of 11.14% of the good prospects for development, hydraulic couplings but also attracted a lot of foreign investment in the industry. According to incomplete statistics, nearly two years fluid sealing industry to invest no less than 30 billion yuan, including construction machinery and other hydraulic hosting industry investment funds accounted for approximately 50% of total investment. Sany, Liugong, Long Engineering , Zoomlion, Shandong Changlin construction machinery and a number of well-known enterprises have invested or hydraulic corporate mergers and reorganizations. China is currently seeking high-end break more than 20 tons of hydraulic excavators used for basic control in the hands of an enterprise that Kawasaki company. Each discussed the matter, sand Bossen are solemnly. Domestic high-end hydraulic manifold block the kinds of situation, has attracted national attention. October 2011, after six months of planning, engineering machinery with high-pressure hydraulic manifold system industrialization and application of the preparatory body established collaborative work platform. Under the guidance of government departments in the industry, driven by the working platform focused on the China Construction Machinery Industry Association and the China Hydraulics Pneumatics & Seals Association, two associations of superior forces to HMB as a breakthrough, hose assembly taking manifold and accessories production Gakken a combined form, increased industry consolidation, the establishment of effective docking platform, and strive in the next 3 to 5 years to break China's construction machinery industry hydraulic and other accessories on foreign dependence.
