Today Durable Hydraulic Oil Filter Supplier will share some relevant knowledge about hydraulic oil filters.
First of all, let's understand the scope of application of hydraulic oil filters.
1. It is used for filtering of hydraulic system of rolling mill and continuous casting machine and filtering of various lubrication equipment.
2. Petrochemical: Separation and recovery of products and intermediate products in the process of oil refining and chemical production, purification of liquids, purification of tapes, optical discs and photographic films in manufacturing, oilfield injection well water and natural gas removal of particulate filtering
3. Textile: Purification and uniform filtration of polyester melt in the drawing process, protection and filtration of air compressor, oil and water removal of compressed gas.
4. Electronics and pharmaceuticals: pretreatment filtration of reverse osmosis water and deionized water, pretreatment filtration of washing liquid and glucose.
5, mechanical processing equipment: papermaking machinery, mining machinery, injection molding machines and large precision machinery lubrication system and purification of compressed air, tobacco processing equipment and dust recovery and filtering equipment spraying equipment.
6. Railway internal combustion engine and generator: filtering of lubricating oil and engine oil.
7.Various hydraulic oil filters for automobile engines and engineering machinery, ships and trucks.
8. Thermal power and nuclear power: purification of gas turbines, boiler lubrication systems, speed control systems, bypass control systems, purification of feed pumps, fans and dust removal systems
9. Various lifting and handling operations: lifting, loading and other construction machinery to special vehicles such as fire fighting, maintenance, handling, ship cranes, anchor cranes, blast furnaces, steelmaking equipment, ship locks, door opening and closing devices, The theater's lifting orchestra and lifting stage, various automatic conveyor lines, etc.
10. Various pushing, squeezing, pressing, cutting, cutting, digging and other operating devices that require force: hydraulic presses, die-casting, forming, rolling, rolling, drawing, shearing equipment for metal materials, plastic injection molding machines, plastic Extruder and other chemical machinery, tractors, harvesters, and other agricultural and forestry machinery for felling and digging, tunnel, mine and ground excavation equipment, steering gear of various ships, etc.
In addition, we should know the maintenance method of Hydraulic Filter:
1. Before replacing the original hydraulic oil, check the oil return filter, oil suction filter, pilot filter to see if there are iron filings, copper filings or other impurities. In some cases, there may be failure of the hydraulic components. After troubleshooting, clean the system. .
2. All hydraulic oil filters (return oil filter, suction filter, pilot filter) must be replaced at the same time when changing hydraulic oil, otherwise it is equivalent to not changing.
3. Distinguish the hydraulic oil markings. Do not mix hydraulic oils with different markings and brands. They may react to deteriorate and produce floc. It is recommended to use the specified oil for the excavator.
4. Before refueling, an oil suction filter must be installed. The nozzle covered by the oil suction filter leads directly to the main pump. If the impurities are light, the main pump will be accelerated and the pump will be worn.
5. Refuel to the standard position. There is usually an oil level gauge on the hydraulic oil tank. See the liquid level gauge. Pay attention to the parking method. Generally, all the oil cylinders are retracted, that is, the forearm and bucket are fully extended and landed.
6. Pay attention to the main pump to exhaust air after refueling. Otherwise, there will be no movement of the whole vehicle for a while, the main pump will be abnormal (air sonic boom), and the air pocket will damage the main pump. The method of exhausting air is to loosen the pipe joint directly on the top of the main pump and fill it directly.
The above is the introduction of the hydraulic oil filter introduced by the Oil Filter supplier, I hope to help everyone.
