经验证明,液压支架的最不可靠和最昂贵零部件是液压传动装置,其价值占整个液压支架总价值的50％以上。液压系统的污染和工作液的损失是液压传动装置工作可靠性和稳定性下降的主要原因。其结果是在工作过程中零件早期磨损和发生故障,研究结果证明,由于液压系统高度污染引起的磨损占液压系统总故障的50—80％,所以其寿命大大降低。 工作液的性质是保证工作可靠性和稳定性的决定性因素。因此,工作液的机械化制备和再生可在大大降低液压部件维修和技术服务的劳动量及材料消耗而使液压部件的寿命提高好多倍。例如,只要工作液被固体颗粒污
Experience has shown that the most unreliable and expensive parts of hydraulic supports are hydraulic drives, which make up more than 50% of the total value of the entire hydraulic support. Hydraulic system pollution and the loss of working fluid hydraulic transmission is the main reason for the decline in reliability and stability. The result is early wear and tear of parts during work, and the results show that their life is significantly reduced due to the wear and tear caused by the highly contaminated hydraulic system which accounts for 50-80% of the total hydraulic system failure. The nature of the working fluid is a decisive factor in ensuring work reliability and stability. Therefore, the mechanized preparation and regeneration of the working fluid can improve the life span of the hydraulic components by a factor of many, greatly reducing the labor and material consumption for hydraulic component repair and technical services. For example, as long as the working fluid is contaminated with solid particles
