二 开机总程序1精要.docVIP

开机总程序（开机准备、开机步骤、停机步骤　） Start program (prepare, start operation, stop operation) 开机准备： Prepare 准备相关物品：原料，辅料，喷丝板，过滤片，包装物，铅笔， 纸管，脱模剂（雾化硅油）等 Prepare relation stuffs: material, MB, spinneret, mesh, cover, pencil, paper tube, spry etc.. 开机条件： 开机以螺杆启动时间为基准 Start condition: start benchmark by extruder start time 提前15小时启动箱体加热油炉，注意观察压力。升温 期间也要注意巡检,首先设定温度110℃，保温1小时,再次设定至工艺温度230℃左右。 Before 15 hours start die heating oven and check the pressure. Check the machine timely. First set temp.110 ℃,after 1 hour set to techincs temp.230℃ ②箱体保持洁净，将清洗组装完毕的分配板和喷丝板安 装到箱体上，注意过滤片的安置形式。 Keep die clean, install spinneret and distribution plate on die, and check the mesh direction. ③箱体加热油炉油温达到工艺温度3小时之后，开始二次紧 固喷丝板（热紧）。 Tight spinneret again after die heating oven reached technice temp. 3 hours . ④提前6小时启动回料螺杆升温系统。到达设定温度后，要 恒温4小时以上。并且注意与大螺杆的连接处的升温和保温。 Before 6 hours start co-extruder heating system. Keep temp. 4 hours after temp.reached setting temp.. Pay attention to heating and warm keeping of the joint with extruder . ⑤提前4小时启动轧机加热油泵。当升温至70℃时，一定 要转动轧机和网帘。轧机启动后要注意观察轴承润滑油的流动状态。 Before 4 hours start calendar heating pump. Must running canlinder and spinbelt when temp. reached 70℃.Check bearing lubrication oil current when calendar started. ⑥提前4小时启动车间冷却水泵。观察水量和压力，防止缺 水。 Before 4 hours start water pump. Check water current and pressure, make sure has enough water. ⑦提前4小时启动螺杆电加热系统。注意确保螺杆头部冷却 水处于流通状态。如果断水，会导致环结堵料，甚至可能导致螺杆大修。螺杆温度到达设定温度后，应恒温2小时，才可以启动螺杆驱动电机。　　　　　　　　　　　　　　　　　　　　 Before 4 hours start extruder heating system. Make sure the recycle water flow on extruder head. Inside of extruder will blocked if water short in there. ⑧提前2小时启动空压机。注意空压机的排水。 Before 2 hours start air compressor, and clean the water. ⑨提前2小时启动预压辊的电加热系统。加热过程中应处于 转动状态，同时必须启动成网机并放下预压辊。 Before 2 hours start pro-pressure roll heating system. Must start spinbelt and put pro-pressure down when hearting program. ⑩提前0.5小时生产线联动试机，并做增减速试验。 Before 0.5 hours start test the speed on link. 提前0.5小时启动吸
