一般来说,机械密封用于密封碱、盐溶液较为困难。因为,一方面必须考虑防止摩擦副受结晶颗粒的损害以及运动部位阻塞;另一方面还要防止腐蚀。往往在清澄的介质中使用非常好的机械密封,一旦用于上述场合,若不采取相应措施,就会在很短时间内使机械密封失效。为了解决碱泵密封问题,笔者设计制造了 In general, mechanical seals are used to seal bases and saline solutions more difficult. Because, on the one hand, it must be taken into account to prevent the friction pair from being damaged by the crystalline particles and clogging of the moving parts; on the other hand, corrosion must also be prevented. Often in the clear medium to use a very good mechanical seal, once used in these circumstances, if not take the appropriate measures, it will be in a very short period of time to mechanical seal failure. In order to solve the problem of alkali pump seal, I designed and manufactured
