1、升降機廠家介紹清除鐵鑄氣缸等處水垢時，可將濃度為8%~10%的鹽酸及相當于鹽酸量3%的若丁緩蝕劑溶液加熱至50-60℃后注入水套內，浸2-3小時后排出，再用加有重鉻酸鉀的水溶液進行清洗，或用5%濃度的苛性鈉水溶液注入水套內，中和殘留的酸溶液。然后用清水沖洗幾次，直到清洗干凈為止。
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、升降機廠家介紹可采用堿性溶液清除油污。對零件表面的動植物油脂和礦物油脂的清除，可采用固態復萌性溶液加入少量乳化劑，經加溫后清洗。若采用壓力噴射，效果更佳。清洗完后，再用加熱的清水噴射，沖洗掉零件表面殘留的堿溶液。
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、升降機廠家提醒為防止堿溶液對精密零件的腐蝕，一般可采用有機溶劑進行清洗。另外因堿溶液對鋁合金有強烈的腐蝕作用，而有機溶劑成本高昂，因此在清洗鋁合金零件時，可配制鋁合金清洗液。
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.
