纺丝停线及PET关阀的过程优化

Process optimization of spinning stop and polyester valve shutoff

为解决我公司纺丝电改煤期间纺丝停线及PET关阀时造成相应增压泵后压力波动,进而影响其余正常运行生产线的问题,采取纺丝车间单个位满卷后拉停相应计量泵,并使用专用销子卡住计量泵,之后通知PET关闭熔体阀门。

In order to solve the problem that the pressure fluctuation of the corresponding booster pump,thereby affecting the normal operation of the remaining production line,which is caused by the spinning stop and the polyester valve shutoff during the spinning electric coal modification process.Taking the measures that in spinning workshop after the single position full lap to pull off the corresponding metering pump,and use special pin to stick metering pump,then notice to close the polyester melt valve.
