Double filter hydraulic oil filter element is composed of two stainless steel filters in parallel, with novel and reasonable structure, good sealing, strong circulation capacity, easy operation and many other advantages, a wide range of applications, strong adaptability of multi-purpose filtration equipment. Especially the filter bag side leakage probability is small, can accurately ensure the filtration accuracy, and can quickly replace the filter bag, filter basically no material consumption, so that the operation cost is reduced. 1, chemical, petrochemical production of weak corrosive materials, such as: water, ammonia, oil, hydrocarbons and so on. 2. Corrosive materials in chemical production, such as caustic soda, concentrated sulfuric acid, carbonic acid, acetic acid, etc. 3, refrigeration of low temperature materials, such as: liquid methane, liquid ammonia, liquid oxygen and a variety of refrigerant. 4, light industrial food, pharmaceutical production has health requirements of the material, such as: beer, drinks, dairy products, food pulp medical supplies, etc..
Installed double filter, hydraulic oil filter to use when using, should pay attention to control box, sensors, and the protection of the transmission parts, prevent damage, in accordance with the stainless steel self-cleaning filter the direction of the arrow tips on ontology connection pipeline mode of electric parts, please pay attention to and identify the motor rotation direction when installation should consider to facilitate maintenance, and should install bypass pipe. When installing, the sewage outlet should be at the bottom as far as possible to facilitate the discharge of sundries. The sewage pipe should not be too long if it is connected to the sewage ditch. 1. Filtration area: 0.15㎡, 0.30㎡, 2. Filtration capacity: 5T /h, 10t/h; 3. Applicable temperature: 120℃; 4. Mesh aperture: 60 ~ 400 mesh (optional); 5. Work stress: ≤ 0.2 MPa. 6. Filter material: 304/316L; 7. Inlet and outlet pipe diameter: 32mm, 40mm; 8. Inner and outer surface treatment: inner mirror polishing, outer mirror polishing or matt.
Double filter hydraulic oil filter core maintenance method: before changing the original hydraulic oil, check the oil return filter element, oil absorption filter element, pilot filter element, to see whether there are iron scraps copper scraps or other impurities, if there may be hydraulic component failure, maintenance and elimination, cleaning system. When changing hydraulic oil, all hydraulic oil filter elements (oil return filter element, oil absorption filter element, pilot filter element) must be replaced at the same time, otherwise it is equivalent to not changed. Identify the hydraulic oil label, different grades, different brands of hydraulic oil is not mixed, may react and deteriorate to produce flocculent.
Oil absorption filter must be installed before refueling, oil absorption filter cover pipe mouth directly to the main pump, into the impurities light speed up the main pump wear, heavy pump. Fuel to the standard position, there is usually an oil level gauge on the hydraulic tank, look at the level gauge. Pay attention to the parking mode, generally all cylinders are fully recovered, that is, the forearm, bucket fully extended and landing. After filling the oil, pay attention to the main pump to exhaust air, otherwise the light is temporarily the whole car no action, the main pump abnormal sound (air sonic boom), or the cavitation damage to the main pump. The method of air exhaust is to loosen the pipe joint at the top of the main pump and fill it up directly.
The main applications of hydraulic oil filter: petrochemical: separation and recovery of products and intermediate products in refining and chemical production process, liquid purification, purification of tape, CD and photographic film in manufacturing, oil field injection well water and natural gas in addition to particle filtration. Textile: purification and uniform filtration of polyester melt in the process of wire drawing, protection and filtration of air compressor, oil and water removal of compressed gas. Electronic and pharmaceutical: reverse osmosis water, deionized water pretreatment filtration, detergent and glucose pretreatment filtration. Mechanical processing equipment: paper-making machinery, mining machinery, injection molding machine and large precision machinery lubrication system and compressed air purification, tobacco processing equipment and spraying equipment dust recovery and filtration. Railway internal combustion engines and generators: filtration of lubricating oil and oil. Hydraulic oil filter for automobile engine and construction machinery, ship and truck.
