【正文】 For Newton, Nien transmission fluid friction law, the sticky liquid to impart dynamism to. Hydraulic transmission is the basic hydraulic ponents and hydraulic Bianjuqi coupled device. Hydraulic coupled devices are a fundamental ponent of a number of radial plane leaves, a work of the pump and turbine round. Hydraulic transmission oil in the work of the cycle of highspeed mobile transmission power, oil pumps round her so involved with the campaign because centrifugal force role do centrifuge campaign from pumps round (and imported axis) and to absorb mechanical energy into moment of momentum (mVR) incremental, highspeed Yeliu round water from the pump to the heart to do turbine flow release moment of momentum. promote turbine (and export axis) rotation, workdriven plane (and load) homework. Hydraulic Bianjuqi basic ponents are pumps round, and the turbineround, they are a space (bending) leaves work round by the work of a relevant order. Hydraulic transmission oil pumps were working round theturbine mix for incremental Ye Liu was moment of momentum, after transferround water turbine Yeliu direction after the release of moment of momentum (kiic energy) to promote the work of the turbinedriven rotary rush. My hydraulic ponents in the development of faster, 2021 hydraulic coupled devices produced about 70,000 National Taiwan. Widely used for Daishishusongji, rail carriers, ball mill, airpressors, pressors, pumps and fuel pumps, and other equipment, transmission, improve transmission quality and energy conservation. My hydraulic coupled with the current maximum output rotational speed for 6500r/min, minimum power to , the maximum power to 7100kW. Hydraulic trend is coupled with a high rotational speed and power. International hydraulic coupled device products to the most famous German Fuk under special pany, according to information that has reached 20210r/min rotational speed and power to 55000kW products, which are still visible in considerable gap. Of course, the power of the big oil hydraulic ponents for hydraulic transmission requirements higher. Hydraulic Bianjuqi mainly for engineering machinery, machinery and diesel oil. Hydraulic Bianjuqi main internal bustion engine with matching applications, the scope of its rotational speed in 2021~3000r/min. Mechanical engineering applications more, the greatest power 700HP about output about 70,000 Taiwan. Oil machinery applications less power to 1500HP. Diesel applications less power up 3000HP. Nien transmission fluid is a liquid transmission doors emerging disciplines in the country are still at an infancy stage. Because liquid Nien transmission products (such as fluid mechanics using Nien) and hydraulic transmission products (such as governorhydraulic 安徽工 程大學(xué)機(jī)電學(xué)院畢業(yè)設(shè)計(jì)（論文） 31 coupled device) Notwithstanding the different nature, but because of similar performance and the same purposes (governor energy), in a number of technical activities (such as the formulation of development plans, standards,technology management,orders,and other activities) are regarded as the same type, with the hydraulic industry monalities, itis anotherchapter on thework of its product mix and transmission oil. Firstly, the performance characteristics of the oil and hydraulic transmission hydraulic transmission oil development not only as a transmission medium for work, but also to provide lubrication bearings and gear while the carrier is further bad fever, heat away. Hydraulic transmission oil is a plex and require specialized research topics, which is directly related to the reliability of hydraulic ponents, transmission efficiency and service life. Should arouse the attention of extensive indepth study. Hydraulic transmission oil should meet the following requirements: First. A suitable lowviscosity liquid viscosity, liquid indicate friction within small, mobile resistance small loss may reduce hydraulic ponents hydraulic losses。 風(fēng)機(jī)外罩清洗裝置液壓系統(tǒng)設(shè)計(jì)及仿真 28 參考文獻(xiàn) [1] 陳大先 .機(jī)械設(shè)計(jì)手冊(cè) [M].北京：化學(xué)工業(yè)出版社， 1993 [2]張人杰 .液壓缸的設(shè)計(jì)制造和維修 [M].北京：機(jī)械工業(yè)出版社， 1993 [3]冀宏，唐鈴鳳 .液壓氣壓傳動(dòng)與控制 [M].北京：華中科技大學(xué)出版社 .
