Polypropylene spinning machine overall solution

The role of polypropylene spinning machine is to melt the melt through the corners into the spinning box, the metering pump from the spinning head, the condensed solid into the wire, and through the corridor to continue the final winding molding. Filament spinning machine mainly by the spinning control system, biphenyl boiler control system, winding machine control system composed of several parts.

Spinning control system mainly includes metering pump drive control, oil pump drive control and some field temperature, pressure signal acquisition records. Each field is equipped with a button box, metering pump and oil pump start and stop control by the scene button, so the frequency of the enable signal is generally given by the terminal can be. As the metering pump and oil pump are synchronous motor, so the frequency of only the general open-loop control. The difference between the metering pump and the oil pump control is that the metering pump is normally driven by the drive, and the oil pump is driven by the inverter.
