【正文】 s and the work cycle. Hydraulic pump station is installed, Manifold or valve bination, t anks, a bination of electrical boxes. Functional ponents : Pump device is equipped with motors and pumps, hydraulic station is the source of power. to mechanical energy into hydraulic oil pressure can be. Manifold from hydraulic valve body and channel assembled. Right direction for implementation of hydraulic oil, pressure and flow control. Valve portfolio plate valve is installed in up board after board conn ects with the same functional IC. Tank plate welding semiclosed containers, also loaded with oil filtering work, air filters, used oil, oil filters and cooling. Electrical boxes at the two patterns. A set of external fuse terminal plate。 distribution of a full range of electrical control. Hydraulic Station principle : motor driven pump rotation, which pump oil absorption from the oil tank. to mechanical energy into hydraulic pressure to the station, hydraulic oil through Manifold (or valve binations) realized the direction, pressure, After adjusting flow pipe and external to the cylinder hydraulic machinery or motor oil, so as to control the direction of the motive fluid transformation force the size and speed the pace of promoting the various acting hydraulic machinery. A development course China Hydraulic (including hydraulic, the same below), pneumatic and seals industrial development process can be broadly divided into three phases, namely : 20 early 1950s to the early 1960s, the initial stage。s and 70 for specialized production system 。s growth stage for the rapid development stage. Which, hydraulic industry in the early 1950s from the machine tool industry production of fake Sugrinder, broaching machine, copying lathe, and other hydraulic drive started, Hydraulic Components from the plant hydraulic machine shop, selfoccupied. After entering the 1960s, the application of hydraulic technology from the machine 2 gradually extended to the agricultural machinery and mechanical engineering fields, attached to the original velocity of hydraulic shop some stand out as pieces of hydraulic professional production. To the late 1960s, early 1970s, with the development of mechanized production, especially in the second automobile factory in providing efficient, automated equipment, along with the Hydraulic Components manufacturing has experienced rapid development of the situation, a group of SMEs have bee professional hydraulic parts factory. 1968 China39。s reform and opening up policy guidelines, with the development of the machinery industry, based mainframe pieces behind the conflicts have bee increasingly prominent and attracted the attention of the relevant departments. To this end, the Ministry of the original one in 1982, formed the basis of mon pieces of Industry, will be scattered in the original machine tools, agricultural machinery, mechanical engineering industries centralized hydraulic, pneumatic and seals specialized factories, placing them under mon management infrastructure pieces Bureau, so that the industry in the planning, investment, technology and scientific research and development in areas such as infrastructure pieces Bureau of guidance and support. Since then entered a phase of rapid development, has introduced more than 60 items of advanced technology from abroad, including more than 40 items of hydraulic, pneumatic 7. After
