固定升降机的水垢如何清除？

1、可以使用苛性钠溶液除固定升降机http://www.jnyuexiang.com/水垢，如果是根除以硅酸盐为主要成分的水垢的时候，可将2%-3%的苛性钠水溶液参加冷却系统内，待机车行进1-2天后放出，用清水冲刷，如此重复1次，最后用清水完全清洁冷却系统。
You can use a caustic soda solution in addition to elevator fixed scale, if eradication with silicate as the main component of the scale, about 2-3% of caustic soda solution in the cooling system within and standby dealers in 1-2 days

after the release, washing with water, repeat 1 time. Finally, with pure water completely clean cooling system.

2、如果是根除固定升降机http://www.jnyuexiang.com/的铁铸气缸等处的水垢的时候，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洁，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。然后用清水冲刷几回，直到清洁洁净停止。
If it is to eradicate the elevator fixed iron casting cylinder, etc. the scale, the concentration of 8% ~ 10% hydrochloric acid and is equivalent to 3% of the quantity of hydrochloric acid rodine corrosion inhibition agent solution is heated to 50 to 60 DEG C after the injection in a water jacket, soak 2-3 hours after discharge and use the aqueous solution of potassium dichromate cleaning, or with 5% concentration of caustic soda solution injection in the water jacket, and the residual acid solution. And then wash with water until clean and clean.
