目前,常用的轴封有填料函式,机械密封式及填料动力密封式(刃口封式)……等等。 填料函式轴封是在转轴与泵壳之间填塞弹性材料,它是依靠填料和轴(或轴套)的外表面接触来实现密封的。这种密封在运转中填料与轴(或轴套)始终摩擦,摩擦十分 At present, the commonly used shaft seal packing function, mechanical seal and packing power seal (edge ​​seal) ...... and so on. Stuffed shaft seal is the elastic material between the shaft and the pump casing, which is sealed by the contact between the packing and the outer surface of the shaft (or sleeve). This seal in operation packing and shaft (or sleeve) always friction, friction is very
