Hydraulic transmission oil is a complex and require specialized research topics, which is directly related to the reliability of hydraulic components, transmission efficiency and service life. Should arouse the attention of extensive in-depth study.Hydraulic transmission oil should meet the f

15、ollowing requirements: First. A suitable low-viscosity liquid viscosity, liquid indicate friction within small, mobile resistance small loss may reduce hydraulic components hydraulic losses; But lubricant sealed perspective, the viscosity can not be too low. Provide lubrication and therefore should

16、meet the requirements of sealed premise as a low-viscosity liquid to improve hydraulic components transmission efficiency. Wen Xing Nien also called liquid than for the high-temperature or low-temperature, and still maintain an effective lubricant sealed. Secondly. A greater emphasis on the hydrauli

The performance can have a stable bubble, aging and sedimentation. Fourthly. Suanzhi sealed pieces to be neutral to low, and a good compatibility, not dwe

18、ll inflation, not dissolved the non-corrosive metal. Fifthly. A higher flash point and lower congeal point hydraulic components 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, low-temp

19、erature environment for the benefit of the start-up of hydraulic components. 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 oil-based

20、products, has used the water or other liquid Nanran （coal mine explosion and fire in defense applications）. Domestic hydraulic components commonly used 6th hydraulic transmission oil （also useful 8th hydraulic transmission oil）, and sometimes to 22 turbine fuel substitutionDiesel oil is dedicated to

21、 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 0.2%; 5

22、0 degrees in the new oil viscosity higher than 6% mounted; Mechanical impurities （benzene Burong objects） to reach 0.2%; A high lipid intake or Suanzhi; Excessive bubble effects transmission power. More articles on the diesel-hydraulic transmission oil outside the oil will definitely reference value

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.

33、 Fluid mechanics starts with the mechanics of hydraulic Nien coupled devices, are in the rotational speed electrical driven downward in the low-speed, power and small, inefficient. To this end in fluid mechanics using input Nien before or after the installation of vertical transmission-export, or to meet with the power machine and the matchin
