One: residual such as paint peeling, welding slag, etc. during assembly. Before assembly, the inner surface of the fuel tank must be strictly cleaned, and the inner wall of the fuel tank must be painted after strict rust removal and oil stain removal.
二： 由外界侵人的此时油箱应注意防尘密封，并在四柱液压机油箱顶部安设空气滤清器和大气相通，使空气经过滤后才进人油箱。可配装100目左右的铜网滤油器，以过滤加进油箱的油液；也有用纸芯过滤的，效果更好，但与大气相通的能力差些，所以纸芯滤芯容量要大。为了防止外界侵人油箱内的污物被吸进泵内，油箱内要安装隔板，以隔开回油区和吸油区。通过隔板，可延长回到油箱内油液的休息时间，可防止油液氧化劣化,另一方面也利于污物的沉淀。隔板高度为油面高度的3/4。 液压砖机油箱底板应倾斜，底板倾斜程度视油箱的大小和使用油的黏度而定，一般在油箱底板低部分设置放油塞，使堆积在油箱底部 的污物得到清除。吸油管离底板髙处的距离要在150加10以上，以防污物被吸人。
Three: reduce the generation of dirt in the system
a. Prevent the generation of condensed moisture in the fuel tank: an air filter with sufficient capacity must be selected to discharge the heated air on the top of the fuel tank as soon as possible, and will not condense into water droplets on the cold fuel tank cap and fall into the fuel tank; On the other hand, the large-capacity air filter or vent can eliminate the difference between the space on the top of the fuel tank and the atmospheric pressure, and prevent dust from being brought in from the outside when the top layer.
B. Use lubricating oil with good rust resistance to reduce the generation of wear and rust prevention.
