为了解决润滑油供求紧张,我们用无油润滑技术对空气机进行了改造。在改造过程中,主要解决了以下三个问题: 1.用四氟乙烯活塞环代替铸铁活塞环。为减少同气缸的摩擦,保持有较好的弹性,起初在活塞环内圆面上对称地钻铰孔,安装六只阀片小弹簧,结果由于弹性太强,摩擦系数大,运转四个班使气缸缸体温度很快升至180至210摄氏度,电流亦略升高,一级缸压力降至1.2Kg以下,工作压力低。经拆检分析,发现四氟塑料环有硬化结焦现象,排气阀阀片上
In order to solve the tight supply and demand of lubricants, we use non-oil lubrication technology to transform the air machine. In the process of rebuilding, the following three problems are mainly solved: 1. Replace the cast iron piston ring with the tetrafluoroethylene piston ring. In order to reduce the friction with the cylinder, to maintain a good flexibility, initially symmetrical on the piston ring ring drilling reaming holes, the installation of six small pieces of valve springs, the result is too flexible, friction coefficient, running four classes The cylinder cylinder temperature quickly rose to 180 to 210 degrees Celsius, the current is also slightly higher, a cylinder pressure dropped to 1.2Kg below the working pressure is low. After demolition analysis, found that the PTFE ring hardened coking phenomenon, the exhaust valve on the valve
