Detection of water volume of filter hydraulic oil in oil filter

(1) volume concentration. That is, the volume ratio of water to the sample (V/V) or the volume fraction per million (PPM). For example, ul/L is mainly used for moisture content in gas samples, called ppm? That is, parts per million, such as 1ppm, or 1 ppm.
(2) mass concentration. That is, the mass ratio of water to the sample (m/m) or the quality of the most ppm, such as ug/kg, mg/kg, etc., is mainly used for liquid and solid samples. (3) weight volume concentration. That is to say, in a fixed volume sample, the weight of water is expressed in terms of W/V or ppm, ul/L, mg/L and so on. This unit is used in liquid samples.
(4) dew point concentration. That is, the relation between dew point and water content in gas. Dew point is under an atmospheric pressure. The temperature condensed by the water vapor in the gas flow to the saturated surface is called the dew point that is balanced with the liquid phase; the equilibrium of the solid phase is called the frost point. As the water vapor pressure of the dew point (Frost Point) is determined, the temperature of the dew point (Frost Point) is given, that is, the vapor pressure of the vapor in the gas sample is indicated as the saturated water vapor pressure at that temperature. It is more convenient in some production departments and some test instruments, often dew point, and with the conversion table of dew point and moisture content in gas.
(5) relative humidity. At the same temperature, the ratio of water vapor pressure to saturated vapor pressure in gas sample is expressed as a percentage.
Hydraulic oil is the hydraulic medium used by the hydraulic system of liquid pressure energy. It plays the role of energy transfer, anti-wear, system lubrication, anticorrosion, rust prevention, cooling and so on in the hydraulic system. For hydraulic oil, the fluid viscosity should be met at working temperature and starting temperature first, because the viscosity change of the lubricating oil is directly related to the hydraulic action, transfer efficiency and transmission precision, and the viscosity and shear stability of the oil should be required for various uses. There are many kinds of hydraulic oil and different classification methods. For a long time, they are classified by use and classified according to the types of oil, chemical components or combustibility. These classification methods only reflect the earning of oil products, but lack of systematicness, and it is difficult to understand the relationship and development of oil products.
Biodegradable hydraulic oil is developed to meet environmental requirements and control environmental pollution. Mainly plant base oil and synthetic vinegar. Plant oil is the main development direction of environmental protection lubricating oil because of its natural biodegradability, excellent lubrication and viscosity temperature performance, rich resources and relatively low price. This hydraulic oil has no formal product hydraulic oil in our country. But there are many foreign countries, such as Ruian Bo and so on, which are made from vegetable oil base oil and can be degraded finally.
Biodegradable hydraulic oil is an excellent wear resistant hydraulic oil, specially designed to meet the requirements of various hydraulic equipment. This series of products can extend the service life of the oil / oil filter and protect the equipment most effectively, thereby reducing maintenance cost and product handling expenses. This series of products are developed jointly with the main equipment manufacturers, which can meet the strict requirements of high hydraulic and high output pumps for the precision hydraulic system, and also meet the strict requirements of other components of the hydraulic system, such as low clearance servo valves and high precision CNC machine tools. This series of products conforms to the most stringent performance requirements for various hydraulic systems and component manufacturers designed by multi metallurgical technology, and the single product has outstanding performance characteristics.
