FLUSHING HYDRAULIC SYSTEM 冲洗液压系统 During the assembly and installation of extensive hydraulic system with many pipe runs ,it is easy possible for dirt and other contamination to find their way into the pipes and other items of equipment. Therefore , it is necessary with such system to flush out all the contamination ,so that it cannot have an adverse effect on the operation and life of the equipment. 在装配期间和安装大量的液压系统有许多管道运行时，它很容易使污物和其他污染找到出路的管道和其他设备。因此，非常有必要与这些系统，以清除所有的污染，因此，它不能产生不利影响设备的操作和寿命。 Flushing involves circulating hydraulic fluid through the system at high speed. The fast-flowing fluid carries the particles of dirt along with it to where they can eventually be removed in a separate filter circuit. 法拉盛涉及循环液压油通过该系统在高速。快速流动的液体中颗粒的泥土连同它在那里他们可以最终被取消，一个单独的滤波电路。 The duration and intensity of flushing depend on the cleanliness of system required. 时间和强度的冲厕取决于系统的清洁需要。 1. Preparing the System for Flushing 1、编写冲洗系统 Any part of the system that could be damaged by the flushing must either be replaced by suitable device or be by-passed using pipes or hoses. If necessary , isolate certain units of the system and flush them individually. 任何部分的系统，可破坏的冲厕必须是合适的设备所取代或绕过使用管道或软管。如果有必要，孤立某些单位的制度和冲洗，并个别。 Venting valves must be provided at high points in the pipework system in order to be certain that the pipes and equipment are completely full of fluid. 排气阀门必须提供在高点，管道系统，以确定管道和设备是完全充分的流体。 Drains must be provided at low points an in dead legs so that any dirty fluid can be drained off. 排水沟必须提供一个在低分在死亡的腿，使任何肮脏的流体可以耗尽了。 2. Flushing Unit 2 、冲洗单元 Flushing unit comprises pumps , heater, filters , tank and the necessary connections. 冲洗单元包括泵、加热器、过滤器、水箱和必要的连接 The pumps must be fitted with adjustable pressure relief valves which must be set to a pressure which ensure that the full volumetric flow of the pumps is being passed through the parts being flushed. The capacity of the tank should be at least three times the pump delivery per minute. It should also be at least equal in capacity to t
