Hydraulic oil is a hydraulic medium used in a hydraulic system that utilizes liquid pressure energy. It has the functions of energy transmission, anti-wear, system lubrication, anti-corrosion, anti-rust, cooling, etc. in the hydraulic system. For hydraulic oil, it is first necessary to meet the requirements for the viscosity of the liquid at the working temperature and the starting temperature at the working temperature. Because the change of lubricating oil viscosity is directly related to hydraulic movement, delivery efficiency and delivery accuracy.
What is hydraulic oil?
In addition, the oil’s viscosity-temperature properties and shear stability must meet the various requirements imposed by various applications. There are also various types of oil, and there are also various classification methods. For a long time, there has been a habit of classifying oils according to their uses, and they are classified according to oil type, chemical composition or flammability. This classification method only reflects the cumulative injection of oil products, but it is not systematic, and it is difficult to understand the relationship and development between oil products.
What is the definition of hydraulic oil?
Biodegradable hydraulic oil is developed to meet environmental protection requirements and control environmental pollution. There are mainly vegetable base oils and synthetic vinegar. Vegetable oils have the characteristics of natural biodegradability, excellent lubricating properties, viscosity-temperature properties, abundant resources, and relatively low prices. They are the main development direction of green lubricants. This kind of hydraulic oil has no official product hydraulic oil in our country. However, there are American Ryanbo and other vegetable oil base oil formulas abroad, which can eventually decompose.
Biodegradable hydraulic oil is an anti-wear hydraulic oil with excellent performance, which is specially manufactured to meet the requirements of various hydraulic equipment. This series of products can prolong the service life of oil/oil filter and effectively protect equipment, thereby reducing maintenance costs and product disposal costs. This series of products is jointly developed with major equipment manufacturers, and meets the strict requirements of the precision hydraulic system of the equipment for high hydraulic pressure and high output pumps, and also meets the stringent requirements for hydraulic system components such as low-clearance servo valves and high-precision CNC machine tools. Require. This series broadly meets the stringent performance requirements of various hydraulic system and component manufacturers in multi-metallurgical design, and individual products have excellent performance characteristics.
What are the quality requirements for hydraulic oil?
Hydraulic systems such as automobiles and construction machinery use hydraulic oil as the working medium. In this hydraulic system, because the oil flow is not large and the pressure is high, it is called hydrostatic transmission. The quality of hydraulic oil will have a major impact on the reliability and service life of the hydraulic system. Generally speaking, the quality requirements of hydraulic oil are as follows:
1) Appropriate viscosity and good viscosity performance can accurately and sensitively transmit power under the condition of changing working temperature and ensure the normal lubrication of hydraulic components.
2) Good anti-rust and oxidation stability, not easy to oxidize and deteriorate under high temperature and high pressure conditions, and long service life.
3) It has good foam tolerance, and the foam generated under the working condition of mechanically stirring the oil is easy to disappear, thereby stabilizing the power transmission and avoiding the accelerated oxidation of the hydraulic oil.
