液压机液压体系中过滤器的装置：
Device for filter in hydraulic system of hydraulic press:
吸油管路：首要是用来维护液压泵不吸入较大颗粒的污染物，以及对液压元件起到一定的维护效果。
压油管路：用来维护除了液压泵和溢流阀以外的一切元件，在过滤精确度上，是为10—15um。并且，过滤阻力应小于0.35MPa。
回油管路：一般是在体系油液流回油箱之前，首要是将污染物过滤掉，保证油液的清洁度。
分支管路：用来过滤部分油液，当液压泵流量较大时。因为，其一般是装置在节流阀下游的，所以是不会有压降的，并且，也不必接受体系的工作压力。
体系外过滤：首要是为了消除流量，以及压力动摇所形成的影响，一般是在大型的液压体系中，由独自油泵供油时，对油箱内的油液进行循环过滤，然后达到好的过滤效果，并坚持油液的清洁。
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.
