Hydraulic oil filter element
In the hydraulic system, liming hydraulic oil filter core is mainly used to filter solid particles and colloidal substances in the working medium and effectively control the contamination degree of the working medium.
Dawn hydraulic oil filter element
Widely used in petroleum, chemical, metallurgy, aviation, electronics, electric power, pharmaceutical, environmental protection, atomic energy, nuclear industry, natural gas, refractories, fire equipment and other areas of purification.
According to the installation position in the hydraulic system, dawn hydraulic oil filter core is divided into suction pipeline filter core, pressure pipeline filter core and return pipeline filter core.
Oil suction pipe line filter: oil suction pipe line (oil tank -- hydraulic pump inlet) or installation of oil suction filter core directly in the oil tank is a necessary measure to protect the hydraulic pump. Its accuracy is generally 100~180 million, which is determined according to different self-suction capacity of the pump. Excessive flow resistance leads to air corrosion of the hydraulic pump.
Pressure pipeline filter, oil filter, pipeline is not only to protect its downstream components, as the main oil filter oil pollution, guarantee system through efficient purification of oil itself, also have very good protection effect for hydraulic pumps, filtration precision for 5 to 10 microns, the filter pressure big, vibration also is very hot, the pressure pipeline oil filter the permission of the differential pressure, according to the different pressure levels, in the range of 0.3 ~ 0.7 MPa.As the pressure pipeline oil filter for ground equipment, cost and installation space are taken into consideration.
Return line filter: various contaminants produced by various components in the process of operation can be intercepted by setting the return line oil filter to avoid returning to the oil tank and being sucked into the hydraulic pump again. The allowable pressure difference of return line oil filter is between 0.3 and 0.5MPa according to different pressure levels.The accuracy is determined according to the pollution degree of oil.Back to the oil pipe line filter Settings to consider more factors to some, is one of the important factors of hydraulic impact, especially with the hydraulic cylinder and proportional valve upstream cases, under the high pressure hydraulic cylinder of the reversing and suddenly drop electric proportional valve, will have a great moment of traffic impact, the oil filter filter could do a lot of damage, in the design of return pipe fully when the oil filter to realize, on the structure shall be strengthened.
