1、升降机厂家介绍清除铁铸气缸等处水垢时，可将浓度为8%~10%的盐酸及相当于盐酸量3%的若丁缓蚀剂溶液加热至50-60℃后注入水套内，浸2-3小时后排出，再用加有重铬酸钾的水溶液进行清洗，或用5%浓度的苛性钠水溶液注入水套内，中和残留的酸溶液。然后用清水冲洗几次，直到清洗干净为止。
When the lift manufacturers introduce clear cast-iron cylinder scale, etc., may be a concentration of 8% to 10% hydrochloric acid and hydrochloric acid equivalent to 3% of the amount cytorhodin inhibitor solution is heated to 50-60 ℃ after injection of the water jacket, soaked 2-3 hours after discharge, and then added with an aqueous solution of potassium dichromate is cleaned, or an aqueous solution of 5% caustic soda concentration of injected water jacket, and the residual acid solution. Then rinse several times until clean up.

2、升降机厂家介绍可采用碱性溶液清除油污。对零件表面的动植物油脂和矿物油脂的清除，可采用固态复萌性溶液加入少量乳化剂，经加温后清洗。若采用压力喷射，效果更佳。清洗完后，再用加热的清水喷射，冲洗掉零件表面残留的碱溶液。
Lift manufacturers can introduce an alkaline solution to remove oil. Animal and vegetable fats and oils on the surface of the part of the mineral cleared Reappearance of solid solution can be added to a small amount of emulsifiers, after heating cleaning. If using a pressure jet, the better. After cleaning, spray with water and then heated, washed away parts of the surface residual alkali solution.

3、升降机厂家提醒为防止碱溶液对精密零件的腐蚀，一般可采用有机溶剂进行清洗。另外因碱溶液对铝合金有强烈的腐蚀作用，而有机溶剂成本高昂，因此在清洗铝合金零件时，可配制铝合金清洗液。
Lift manufacturers remind alkali solution to prevent corrosion of precision parts, usually organic solvents can be used for cleaning. Further, because there is a strong alkaline solution of aluminum corrosion effect, and the high cost of organic solvents, so when cleaning aluminum parts, aluminum can be formulated cleaning fluid.
