1.确定更换周期液压油是否更换的确定方法有3种:一是经验判断法,二是固定周期法,三是理化分析法。经验判断法是在现场通过对液压油含水量、外观颜色、气味、黏度、污染程度的简单判断来鉴定油液品质;固定周期法是采取定期更换的方法,即每隔1年或达到规定使用时间就更换1次液压油;理化分析法是采用专业
1. Determine the replacement cycle hydraulic oil is determined by the replacement of three ways: First, the empirical method, the second is a fixed cycle method, the third is the physical and chemical analysis. The experience judgment method is to identify the oil quality by the simple judgment of the water content, appearance color, odor, viscosity and pollution degree of the hydraulic oil in the field. The fixed cycle method is to take the regular replacement method, that is, every 1 year or up to the prescribed use Time to replace a hydraulic oil; physical and chemical analysis is the use of professional
