Device for filter in hydraulic system of hydraulic press:
Oil absorption pipeline: the first is to maintain the hydraulic pump does not inhale larger particles of pollutants, as well as hydraulic components play a certain maintenance effect.
Oil pressure line: to maintain all components except hydraulic pump and relief valve, the filter accuracy is 10 - 15um. And the filtration resistance should be less than 0.35MPa.
Return oil pipeline: usually before the system oil flow back to the tank, the main thing is to filter out the pollutants, to ensure the cleanliness of the oil.
Branch pipe: used to filter part of the oil, when the hydraulic pump flow is large. Because it is generally installed downstream of the throttle valve, so there will be no pressure drop, and do not have to accept the working pressure of the system.
System: the first is to eliminate the filtering flow, pressure and shake the influence formed by the hydraulic system in general is large, the oil pump oil alone, the oil in the oil tank of the loop filter, and then achieve good filtering effect, and keep the oil clean.
