液压凿岩机的工作油是实现其能量转换、传递和控制的工作介质,工作中液压油要承受压力、温度和剪切等作用,同时还要担负润滑、防锈、防腐和冷却零部件等功能,因此对液压油的要求较为严格。国外设备都推荐专用的液压油,国产液压凿岩机如果液压油选择不当或维护保养不好,也就不能很好的发挥设备效率,甚至会影响和破坏它的正常工作。为此,应当把液压油看作和液压系统中各元件同等重要的因素,必须正确选取和维护。一、液压油的选择
The working oil of hydraulic rock drill is the working medium to realize its energy conversion, transmission and control. The hydraulic oil under work must bear the functions of pressure, temperature and shearing. At the same time, it should also bear the functions of lubricating, anti-rust, anti-corrosion and cooling parts, Therefore, the more stringent requirements of hydraulic oil. Foreign equipment are recommended for hydraulic oil, domestic hydraulic rock drill if the hydraulic oil improper selection or maintenance is not good, it can not play a good equipment efficiency, or even affect its normal work. For this reason, the hydraulic fluid should be considered as an equally important factor for the components in the hydraulic system and must be properly selected and maintained. First, the choice of hydraulic oil
