The hydraulic oil filter element is used in the hydraulic system to filter out solid particles and gelatinous substances in the working medium. It also filters out solid impurities generated from external mixing or internal operation of various oil systems. It can effectively control the pollution degree of working medium and protect the normal operation of mechanical equipment. It is an indispensable part of the pipeline series for conveying media. .
The hydraulic oil filter is mainly installed in the hydraulic system: on the oil suction line, on the pressure oil line, on the return line, on the bypass, on a separate filter system.
Product Usage:
The hydraulic oil filter element is an indispensable part of the pipeline series for conveying medium. It is usually installed in the inlet end of the hydraulic system to filter out metal particles and contaminated impurities in the fluid medium to protect the normal operation of the machine.
Hydraulic oil filter has a wide range of applications, covering almost all industries: steel, electric power, metallurgy, shipbuilding, aviation, paper, chemical, machine tools and engineering machinery, construction machinery and other fields.
Main parameters and characteristics:
The hydraulic oil filter is mainly made of stainless steel woven mesh, sintered mesh and iron mesh. Since it uses mainly fiberglass filter paper, chemical fiber filter paper and wood pulp filter paper, it has high concentricity and high pressure. It has good straightness. Its structure is made of single or multi-layer metal mesh and filter material. The number of layers and the mesh number of the mesh are determined according to different use conditions and uses.
Scope of application:
1. It is used for the filtration of hydraulic systems of rolling mills and continuous casting machines and the filtration of various lubrication equipment.
2. Petrochemical: Separation and recovery of products and intermediate products in refining and chemical production processes, purification of liquid purification, tapes, optical discs and photographic film in manufacturing, oilfield injection of well water and natural gas in addition to particle filtration.
3. Textile: Purification and uniform filtration of polyester melt in the drawing process, protection and filtration of air compressor, degreasing and dehydration of compressed gas.
4, electronics and pharmaceuticals: reverse osmosis water, deionized water pretreatment filtration, washing liquid and glucose pretreatment filtration.
5, mechanical processing equipment: paper machine, mining machinery, injection molding machine and large precision machinery lubrication system and compressed air
Purification, dust recovery and filtration of tobacco processing equipment and spraying equipment.
6. Railway internal combustion engines and generators: filtration of lubricating oil and oil.
7. Various hydraulic oil filters for automobile engines and engineering machinery, ships and trucks.
8. Thermal power and nuclear power: purification of gas turbine, boiler lubrication system, speed control system, bypass control system oil, purification of feed water pump, fan and dust removal system
9, various lifting, handling operations: lifting, loading and other construction machinery to fire, maintenance, handling and other special vehicles, ship's cargo lift, anchoring machine, blast furnace, steelmaking equipment, ship locks, ship door opening and closing device, The theater's elevating pool and lifting stage, various automatic conveyor lines, etc.
10. Various working devices such as pushing, squeezing, pressing, shearing, cutting, digging, etc.: hydraulic press, die casting, forming, rolling, rolling, stretching, shearing equipment, plastic injection molding machine, plastic Chemical machinery such as extruders, tractors, harvesters, and other agricultural and forestry machinery for cutting and mining, excavation equipment for tunnels, mines and grounds, and steering gears for various ships.

12, automatic control and control of a variety of work program combinations: combined machine tools, machining automatic lines.
13. Special workplace: working equipment in special environments such as underground, underwater and explosion-proof.
The maintenance method of the hydraulic oil filter is as follows:
1. Put off the original hydraulic oil before changing, check the oil return filter, oil absorption filter, pilot filter to see if there are iron filings or other impurities attached. If there are any hydraulic components failure, after cleaning, the cleaning system .
2. When changing hydraulic oil, all hydraulic oil filter elements (return oil filter, oil suction filter, pilot filter) must be replaced at the same time, otherwise it is equivalent to no change.
3, identify the hydraulic oil label, different grades, different brands of hydraulic oil are not mixed, may react to deterioration and produce flocs, it is recommended to use the excavator to specify oil.
4. Before the refueling, the oil-absorbing filter element must be installed first. The nozzle of the oil-absorbing filter core is directly connected to the main pump. When the impurities are light, the main pump is accelerated and the pump is pumped.
5, refueling to the standard position, the oil tank generally has an oil level gauge, look at the liquid level gauge. Pay attention to the parking mode. Generally, all the cylinders are fully retracted, that is, the arm and bucket are fully extended and landed.
6, after adding the oil, pay attention to the main pump to discharge air, otherwise the light will temporarily no action, the main pump is abnormal (air blast), and the air pocket damages the main pump. The air exhaust method is to loosen the pipe joint directly on the top of the main pump and fill it up directly.
