七、污染控制装置的布置 1.液压系统——开式回路 过滤器在液压系统中的布置按其所实现的三个主要功能分类,即:防止侵入、保持系统清洁度和元件隔离。 (1)防止侵入 进入油箱的空气需经过滤。从空气中清除污染物往往比从油中清除要容易。首先保证油箱是密闭的,所有空气都经过一个口(或大型系统中两个口)进入。该口需配装一个通气过滤器。该通气过滤器设计成从空气中去除3μm以上的颗粒(V-Pak等级10)。所有进 7. Pollution Control Device Arrangement 1. Hydraulic System - The open circuit filter arrangement in the hydraulic system is classified according to the three main functions it has achieved, namely: prevention of intrusion, maintenance of system cleanliness and component isolation. (1) to prevent air intrusion into the tank to be filtered. It is often easier to remove contaminants from the air than to remove it from the oil. First, make sure that the tank is closed and all the air goes in through one of the ports (or two in the larger system). The mouth to be equipped with a ventilation filter. The vent filter is designed to remove particles of 3 μm or more from the air (V-Pak grade 10). All into
