【正文】 pany Nien governor devices into rotational speed 1785r/min exporting rotational speed 5000r/min, transmitting power to 5200kW. My hill Xian too Salih coal mine in the smaller Daishishusongji specifications. Oil is brought by the United States of its transmission. Baoding propeller factory design, produced with structurally similar products. Another is the United States Dodge (Dodge) panies CST fluid mechanics devices Nien, it is in Park pillar gear plaary reducer round of the robustness of the exportround, and export axis (connecting the Sun round), in parallel with export large Chijuan fluid mechanics using Nien (driven friction films fixed), startup liquid separation Nien governor in the state starts (idling), gradually increasing pressure control, when his transmission torque and the torque equivalent output bearings, export axle (with load) started turning and continue to increase the pressure until the joint control of the situation, the export axle assume full power output. CST fluid mechanics device known as Nien large Daishishusongji soft start system in the country39。 But lubricant sealed perspective, the viscosity can not be too low. Provide lubrication and therefore should meet the requirements of sealed premise as a lowviscosity liquid to improve hydraulic ponents transmission efficiency. Wen Xing Nien also called liquid than for the hightemperature or lowtemperature, and still maintain an effective lubricant sealed. Secondly. A greater emphasis on the hydraulic ponents for the moment and the power transmission and liquid working for the redirect, it is liquiddegrees the higher the better. Thirdly. The performance can have a stable bubble, aging and sedimentation. Fourthly. Suanzhi sealed pieces to be neutral to low, and a good patibility, not dwell inflation, not dissolved the noncorrosive metal. Fifthly. A higher flash point and lower congeal point hydraulic ponents work Youwen change significantly, sometimes up to 160 degrees, and therefore require flash point higher than 180 degrees, and congeal point lower than 20 degrees, lowtemperature environment for the benefit of the startup of hydraulic ponents. Sixthly. A good lubricant performance liquid sufficient greasiness to the good parts in the surface material, a good lubricant. At present, and hydraulic transmission applications work more liquid types, among all oilbased products, has used the water or other liquid Nanran (coal mine explosion and fire in defense applications). Domestic hydraulic ponents monly used 6th hydraulic transmission oil (also useful 8th hydraulic transmission oil), and sometimes to 22 turbine fuel substitution. Diesel oil is dedicated to the life of not less than 2,000 hours and for the initial operation of new equipment installed oil after 100 hours and 500 hours of the first, second formula, can still be used after the filter. Is one of the following situations, the need to replace the new oil : Water content greater than %。生產(chǎn)廠(chǎng)有北京汽車(chē)機(jī)油泵廠(chǎng)和長(zhǎng)春第一汽車(chē)制造廠(chǎng)等單位。為了滿(mǎn)足規(guī)定的性能要求，可用不同 的有機(jī)取代基或調(diào)整聚合物分子的大小 (即改變其分子量 )，以變化其粘度或獲得其它性能。這樣可使發(fā)動(dòng)經(jīng)常在最適宜的溫度下工作。汽車(chē)用的硅油風(fēng)扇離合器主動(dòng)盤(pán)與發(fā)動(dòng)機(jī)相聯(lián)，從動(dòng)盤(pán)與風(fēng)扇相聯(lián)，工作液體為粘度較大的硅油。CST 系列產(chǎn)品由美國(guó)供應(yīng)專(zhuān)用液力傳動(dòng)油。保定螺旋漿制造廠(chǎng)設(shè)計(jì)、生產(chǎn)了與之結(jié)構(gòu)相似的產(chǎn)品。為此在液粘調(diào)速離合器的輸入前或輸出端后加裝 齒輪傳動(dòng)，以適應(yīng)與動(dòng)力機(jī)或與工作機(jī)的匹配，如此產(chǎn)生了新的裝置 —— 液粘調(diào)速裝置。 目前國(guó)產(chǎn)液粘調(diào)速離合器多采用 8 號(hào)液力傳動(dòng)油為工作液體。 (2)有離好的潤(rùn)滑性能 (油性和極壓性 )。當(dāng)控制壓力足夠時(shí)小，主、從動(dòng)摩擦片脫離，則輸出轉(zhuǎn)速為零。 液粘調(diào)速離合器與傳動(dòng)油 液粘調(diào)速離合器通過(guò)其主、從動(dòng)摩擦片間的若干油膜來(lái)傳動(dòng)動(dòng)力，依靠油液的粘性主動(dòng)摩擦片 “ 拉著 從動(dòng)摩擦片同方向旋轉(zhuǎn)，傳遞力矩與油液粘度、兩片間“ 滑差 成正比，而與油膜厚度 (片間隙 )成 反比。以上各條對(duì)內(nèi)燃機(jī)車(chē)專(zhuān)用油以外的液力傳動(dòng)油也有一定的參照價(jià)值。 目前，國(guó)內(nèi)外液力傳動(dòng)應(yīng)用的工作液體種類(lèi)較多，除各種石油基產(chǎn)品外，也有采用清水或其它難燃液體的 (煤礦井下為防引燃爆炸而應(yīng)用 )。 性能穩(wěn)定 不易產(chǎn)生泡沫、老化和沉淀。液力傳動(dòng)油應(yīng)能滿(mǎn)足以下要求： 要有適宜的粘度 液體粘度低，表明液體內(nèi)摩擦小，流動(dòng)阻力損失小，可減少液力元件的液力損失；但從潤(rùn)滑密封角度考慮，粘度不能過(guò)低。由于液粘傳動(dòng)產(chǎn)品 (如液粘調(diào)速離合器 )與液力傳動(dòng)產(chǎn)品 (如調(diào)速型液力偶合器 )雖
