本文介绍液压过滤方面的基本资料,包括滤油器的必要性,滤油器的基本型式和位置及其在液压系统中的应用。本资料适用于大多数工业和行走设备的液压装置。有关滤油器的特殊需要及其维护,应询问液压系统中所用元件和油液的制造商。为什么要过滤? 正确的设计过滤系统加上对滤油器进行有条理的维护至少可以消除液压系统故障的百分之七十五。此外,系统元件的寿命得到延长。污垢源多数液压系统反复循环着相同的油。虽然系统是密闭的,但并不防尘。有害污垢和杂质颗粒可能是潜伏的、侵入的或磨损产生的。
This article describes the basic information on hydraulic filtration, including the necessity of oil filter, the basic type and location of oil filter and its application in hydraulic system. This information applies to most industrial and mobile equipment, hydraulic devices. For the special needs of oil filters and their maintenance, the manufacturer of the components and fluids used in the hydraulic system should be consulted. Why filter? A properly designed filter system, coupled with a well-organized maintenance of the oil filter, can eliminate at least 75% of hydraulic system failure. In addition, the life of system components is extended. Dirt Sources Most hydraulic systems repeatedly circulate the same oil. Although the system is airtight, it is not dustproof. Harmful dirt and impurities Particles may be latent, invasive or abrasion-generated.
