【正文】 gap) negatively. Initiative friction films and imported axle and power machine linked to the importation of rotational speed as constants. Driven friction films and the work associated with the export of axle, and the output rotational speed with control pressure changes, spherical tank pressure control, a slick film thinning, export rotational speed rise, and vice versa. When the control pressure enough, the owners, driven friction films together into the transmission straight. When sufficient pressure control small owners, driven films from friction, zero export rotational speed. Nien in fluid mechanics using rotational speed than 01 change from the process of filmfriction conditions showing a liquid friction (a mechanical liquid) mixed friction (purely mechanical) border friction. Therefore fluid mechanics using Nien are in the process of separationstate governor, the state governor and the state face. Work in fluid liquid is the role of transmission Nien transmission power, heat dissipation and cooling lubricant should have the following functions: (1) the appropriate viscosity. (2) A good lubricant performance (greasiness and very pressurized nature). (3) A good oxidation insecurities. (4) Higher than the thermal capacity and higher heat conductivity. In addition to the above requirements, but also work with rustproof liquid role, antibubble capacity, congeal points lower, flash point should be high, not volatile, nontoxic. Nien currently made in China fluid mechanics using more oil as a hydraulic transmission work on the 8th of liquid. The domestic fluid mechanics using a TL Nien and HC type rated rotational speed mostly 1500r/min, individual 3000r/min. 75kW power transmission smallest, the largest of 1100kW. Fluid mechanics starts with the mechanics of hydraulic Nien coupled devices, are in the rotational speed electrical driven downward in the lowspeed, power and small, inefficient. To this end in fluid mechanics using input Nien before or after the installation of vertical transmissionexport, or to meet with the power machine and the matching machine work, so a new device liquid Nien governor mechanics devices Nien current production and application of two different structures liquid Nien governor devices, a category is the . Philadelphia drove parallel axle fluid production 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 planetary 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。s major coal Daishishusongji already applied. CST series products, the importation of rotational speed 1483r/min, rated slowdown than to ~, transmitting power scope 702~3115kW. CST series of products supplied by the United States dedicated hydraulic transmission oil. Thirdly. Silicone oil producing fans with liquid silicone oil work of the fan clutch, driven plate with a 7898 derby leaves, the two derby leaves mutual alternate inserted, a number Park derby gap (oil), use these links, the sticky oil to impart momentum. The process of routing thickness unchanged through changes Chongyou volume and the size of the area to exploration by sheared governor.Engine in the appropriate temperature can be higher fuel efficiency, overheating is not too cold. Automotive firm to offer fans of silicone oil and engine linked driven sites linked with the fans, for liquid silicone oil viscosity larger. On temperature devices for cooling water to control the rear airflow temperature feelings Chongyou volume. When the engine cooling water temperature low, the air currents temperature low temperature equipment made Chongyou small amount of oil sheared small size, transmission moment small, low rotational speed fans for the engine cooling capacity low. Conversely, when the engine cooling water temperature is high, the fans rotational speed is high, awareness of the engine cooling effect. This will allow a regular in the most appropriate temperature. Fuel efficiency, noise small, extended engine lifeSilicone oil used silicone oil is a fan using synthetic lubricants, not petroleum refining e from. It is the semiorganic silicon polymers or copolymer, containing duplicate silicon modules for yuan oxygen machine backbone, and the silicon atoms along the chain, replace clustering levonorgestrel, the general chainguns. To meet the prescribed performance requirements, availability of different organic polymers to replace the base elements or the size of the adjustment (that is, to change its molecular weight), to change its viscosity or acquire other properties.Silicone oil depends on the physical properties of polymer molecular structure, such as molecular weight, organic genetic types and quantity, location and length of extension chain. In the liquid oil thickness constant use silicone oil Nien transmission of the main reasons is that it has a high viscosity, good performance and strong resistance Nien Wen sheared capacity.Silicone oil can be used in all types of vehicles using fans, currently our applications are mainly jeeps, and othe
