由于农业机械液压系统运行中的故障多是由液压油污染和选用不当引起的,其中对液压油选择不当、使用不慎是一个重要方面。因此,正确、合理选用液压油,对提高农业机械液压设备运行可靠性及经济性,延长系统和元件的使用寿命,保证设备安全运行,防止事故发生具有重要意义。1液压油质量状况判断(1)采用手捻法判断液压油黏度。用手来判断黏度的大小时,由于黏度随温
As the hydraulic system in agricultural machinery operation failures are mostly caused by hydraulic oil pollution and improper selection, which improper selection of hydraulic oil, careless use is an important aspect. Therefore, the correct and reasonable selection of hydraulic oil, to improve the reliability of agricultural machinery hydraulic equipment operation and economy, to extend the life of systems and components to ensure the safe operation of equipment to prevent accidents is of great significance. A hydraulic oil quality status judgment (1) Hand twist method to determine the viscosity of hydraulic oil. By hand to determine the size of the viscosity, due to viscosity with temperature
