pp风管管道的清洗过程主要包括：设备检修，清洗风管以及进出风口。检查通风管道的连接是否可靠；检查阀门是否渗漏；分段清洗通风管道；清洗风机及进出风口。
The cleaning process of PP air duct pipeline mainly includes equipment maintenance, cleaning air duct and air inlet and outlet. Check whether the connection of ventilation duct is reliable; check whether the valve is leaking; sectional cleaning of ventilation duct; cleaning of fan and inlet and outlet.
一般FRPP管挤出机的出口压力存在着较大波动，会影响FRPP管的尺寸精度，如果我们在挤出机的出口和模头之间加装一台熔体泵，可以用来稳定挤出机出口压力波动，使得线性挤出成为可能，从而提高FRPP管的尺寸精度，在单位时间内提高挤出机的产量。
Generally, the outlet pressure of FRPP pipe extruder fluctuates greatly, which will affect the dimension accuracy of FRPP pipe. If we install a melt pump between the outlet of extruder and die, it can be used to stabilize the fluctuation of the outlet pressure of extruder and make linear extrusion possible, thereby improving the dimension accuracy of FRPP pipe. Increase the output of the extruder.
