其实造成1000吨液压机液压油污染的原因有很多，由于液压油本生就在不断的产生污染物，就此而言，要彻底解决污染问题是不易的。但为了延长液压元件的寿命，保证1000吨液压机系统工作的完整性，只能将液压油的污染度控制在一限度以内。
为防止油液污染，在实际工作中应采取如下措施。
1. Keep the hydraulic oil clean before use. Hydraulic oil in the transport and storage process will be contaminated by the outside world, the newly bought hydraulic oil looks very clean, in fact, very dirty, must be put a few days later, after filtering into the hydraulic system.
2.使液压系统在装配后、运转前保持清洁。液压元件在加工和装配过程中必须清洗干净。液压系统在装配后、运转前应彻底进行清洗，用系统工作中使用的油液清洗，清洗时油箱除通气孔外必须全部密封，密封件不可有飞边、毛刺。
3. Keep the hydraulic oil clean during work. The hydraulic oil will be polluted by the environment during the working process. Therefore, try to prevent air and moisture from being immersed. In order to completely eliminate the immersion of water, gas and pollutants, seal the oil tank and add air filter on the vent hole.
4. Take the appropriate oil filter. This is an important means to control the pollution of hydraulic oil. According to the requirements of the equipment, different filtering methods, different precision and different structure oil filters should be selected in the hydraulic system, and the oil filter and oil tank should be checked and cleaned regularly.
5. Replace the hydraulic oil regularly. Before replacing the new oil, the oil tank must be cleaned once. When the system is dirty, it can be cleaned with kerosene and drained such as new oil.
随着液压技术在各大工业部门的大量应用，对液压设备的工作可靠性提出了更高的要求。实验证明，液压设备的工作可靠性和寿命与工作介质的污染状态有很大很密切的关系。根据国内外的统计数据，液压和润滑系统中大多数故障是由于液压油的选用不当或使用中、管理不善，导致油液污染造成的，目前液压技术不断向着 高压、集成、小型化发展，加上电子技术的应用，对液压系统工作的可靠性、灵敏度、稳定性和寿命提出越来越高的要求，因此需要选用性能比较好，具有高清洁度的液压油，液压系统污染问题是愈来愈受到国内外各大行业的重视。
液压系统污染控制研究的内容主要有污染物分析、过滤技术、污染磨损、液压元件污染敏感度等。研究的目的是要使液压油的污染控制在关键元件所能承受的范围内，以减少污染磨损，防止突发性鼓掌，提高液压设备的工作可靠性和使用寿命。
