问:机床为什么要换油? 答:因为润滑油在使用过程中,零件摩擦研磨下来的粉末、切屑、空气中尘土、水和纤维物质混入油中,杂质增多;油经较长时间的工作,受大气氧化以及温度、压力的影响,会生成酸性胶质和沥青;同时由于羟的分解,出现沉淀,构成油泥,如不换油会加快机件的磨损和腐蚀,以及堵塞油路。因此,机床要按规定清洗换油。问:冷却液为什么需要更换? 答:冷却液中含有脂肪酸钠皂,PH值一般控
Q: Why do machine oil change? A: Because the lubricant in the process of use, the parts friction grinding down the powder, chips, dust in the air, water and fiber material mixed with oil, impurities increased; oil after a long period of work, By the atmospheric oxidation and temperature, pressure, will generate acid gum and asphalt; the same time due to the decomposition of hydroxyl, precipitation, the formation of sludge, if you do not change the oil will speed up the wear and corrosion and clogging the oil. Therefore, the machine according to the provisions of cleaning oil change. Q: Why do you need to replace the coolant? A: The coolant contains sodium soap soap, PH value of the general control
