液压油在使用一段时间以后,由于污染物和水份的逐渐增多,会影响液压动力设备的正常运行,这时必须更换新油才能保证设备的正常运行。通常粒子污染可以通过连续不断的过滤滤掉。但是,水份是最难对付的问题,过滤往往不可能把水份除掉。只有利用专门的再生设备才能除去水份。油液中的水有两种状态: 1、溶解于油液中。 2、在油液中水呈游离微粒状即乳状液。溶解于油液中的水是根本看不见的。游离水有时象云状物能够看见,但往往最后要消散,致使油液保持清晰。尽管如此,水还是存在,对油液起氧化作用或其它分解作用;而聚集在低处的水使金属氧化。老的再生设备是用离心分离机、聚结剂、
Hydraulic oil in use for some time, due to the gradual increase in pollutants and water will affect the normal operation of hydraulic power equipment, then you must replace the new oil to ensure the normal operation of equipment. Normally particle contamination can be filtered off continuously. However, water is the most difficult problem to deal with, and it is often impossible to remove the water by filtration. Only use special regeneration equipment to remove moisture. There are two states of water in the oil: 1, dissolved in the oil. 2, the water in the oil was free particulate or emulsion. Water dissolved in the oil is simply invisible. Free water can sometimes be seen as a cloud, but often ends up dissipating, leaving the fluid clear. In spite of this, water is still present, which oxidizes the oil or otherwise decomposes; and water that collects in the lower part oxidizes the metal. The old regeneration equipment is used centrifuge, coalescent,
