液压与气动系统外文翻译内容摘要：

ble features of fluid power, it is not a panacea for all power transmission problems .Hydraulic, systems also have some drawbacks. Hydraulic oils are messy, and leakage is impossible to pletely eliminate. Also, most hydraulic oils can cause tires if an oil leak occurs in an area of hot equipment. Now, below a concrete example hydraulic stations to introduce the advantages of the hydraulic system. Hydraulic Station and the development of hydraulic ponenis Profiles Hydraulic Pump Station also known as the stations are independent hydraulic device. It requested by the oil gradually. And controlling the hydraulic oil flow direction, pressure and flow rate, applied to the mainframe and hy draulic devices separability of hydraulic machinery. Users will be provided after the purchase hydraulic station and host of implementing agencies (motor oil or fuel tanks) connected with tubing, Hydraulic machinery can be realized from these movements and the work cycle. Hydraulic pump station is installed, Manifold or valve bination, tanks, 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 connects 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: 60`s and 70 for specialized production system :8090`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 l960s, the application of hydraulic technology from the machine 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 equiment. along with the Hydraulic Components manufacturing has experienced rapid development of the situation, a group of SMEs have bee professional hydraulic parts factory. 1968 China161。 175。 s annual output of hydraulic ponents have nearly in 1973, machine tools, agricultural machinery, mechanical engineering industries, the production of hydraulic parts factory has been the professional development of more than 100 and an annual output more than one million, an independent hydraulic manufacturing industry has begun to take shape. Then , hydraulic pieces of fake products from the Soviet Union for the introduction of the product development and technical design bining the products to the pressure, Hypertension and the development of the electrohydraulic servo valves and systems, hydraulic application areas further expanded . Aerodynamic than the start of the industrial hydraulic years later, in 1967 began to establish professional pneumatic ponents factory, Pneumatic Components only as modity production and sales. Sealed with rubber and plastics, mechanical seals and sealing flexible graphite sealing industry, the early 1950s from the production ordinary 0rings, rubber and plastics extrusion, such as oil seal sealing and seal asbestos products start to the early 1960s, begun production of mechanical seals and flexible graphite sealing products. 1970s, the burning of the former Ministry, a Ministry, the Ministry of Agricultural Mechanization System, a group of professional production plants have been established, and the official establishment of industries to seal industrial development has laid the foundation for growth. Since the l980s, in the country`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 the 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。
