What are the characteristics of high quality hydraulic oil filter element
The hydraulic filter element is applied in the hydraulic system, mainly installed on the oil suction Road, pressure oil circuit, oil return pipeline and bypass, and on the separate filtering system, which is used to filter out the particles and rubber impurities in the system and ensure the cleanliness of the hydraulic system.
In the process of using hydraulic oil, some impurities will be mixed in due to various reasons. The main impurities include mechanical impurities, water and air, etc quality It will accelerate the corrosion, increase the mechanical wear, reduce the working efficiency, make the oil deterioration, reduce the service life of the equipment, and in serious cases, it will cause oil pipeline blockage and cause production accidents.
The hydraulic oil filter element is mainly made of stainless steel woven mesh, sintering mesh and iron woven mesh. As the filter materials used are mainly glass fiber filter paper, chemical fiber filter paper and wood pulp filter paper, it has the characteristics of high concentricity, high pressure, good straightness, stainless steel material, without any burrs, and long service life. Application field of hydraulic oil filter element
1. Automobile engine and construction machinery: air filter, oil filter, fuel filter for internal combustion engine, hydraulic oil filter and diesel filter for truck.
2. Various lifting and handling operations: lifting, loading and other construction machinery to fire fighting, maintenance, handling and other special vehicles, ship's crane, windlass, etc.
3. All kinds of pushing, extruding, pressing, shearing, cutting, digging and other working devices that need force: hydraulic press, plastic injection molding machine, plastic extruder and other chemical machinery, tractors, harvesters and other agricultural and forestry machinery for cutting and digging.
Hydraulic excavators usually need to change the hydraulic oil after running for 2000h, otherwise it will pollute the system and cause system failure. According to statistics, about 90% of the faults in hydraulic system are caused by system pollution. On the basis of checking the color, viscosity and smell of the oil, the oil pressure and air humidity should also be detected.
Under special circumstances, if the machinery uses low-grade diesel (sulfur content in diesel oil is 0.5% - 1.0%), the diesel filter and mechanical filter should be replaced every 150h; if the sulfur content is above 1.0%, the diesel filter and mechanical filter should be replaced every 60H. The hydraulic return oil filter element, pilot filter element and respirator filter element should be replaced every 100 hours for the equipment with heavy load of hydraulic system, such as crusher and vibration rammer.
High quality filter should have high filtration efficiency and long service life, The quality of the ore blending filter is always the most important, so that the product can meet the requirements of the filtering accuracy of the engine under various conditions The core has the following characteristics:
1. Strength requirements, Production integrity requirements, bear pressure difference, bear installation external force, bear differential pressure alternating load 2. Smoothness requirements of oil flow and flow resistance characteristics 3. It is resistant to high temperature and compatible with working medium
