The spinning control system of polypropylene spinning machine mainly includes the transmission control of metering pump, the transmission control of oil pump and the collection and recording of some on-site temperature and pressure signals. Each spinning position on site is equipped with a button box. The start and stop of metering pump and oil pump are controlled by the button on site, so the enable signal of frequency conversion is generally given by the terminal.

Because the metering pump and the oil pump are synchronous motors, the frequency conversion only needs the general open loop control. The difference between the metering pump and the oil pump is that the metering pump is usually driven by a frequency converter, and the oil pump is driven by a frequency conversion, a drag.

Jiangxi Donghua Machinery Co., Ltd. specializes in the production of polypropylene spinning machine, polypropylene medium strength spinning equipment, polypropylene high strength spinning equipment, polypropylene FDY spinning machine, polyester spinning machine, arnylon 1414 fiber spinning equipment, DHP419 series high strength polypropylene spinning drafting machine, polypropylene spinning machine, DHP418 series polypropylene spinning drafting machine, DHkv1235-12 type Polyester spinning machine, DHPE high strength and high modulus polyethylene fiber spinning equipment, DHTA aramid 1414 fiber spinning equipment, HDZF3 high vacuum dynamic drying and solid phase adhesion all-in-one machine, polypropylene fiber spinning machine.

The function of polypropylene spinning machine is to make the melted melt enter the spinning box through the bend, the metering pump is ejected by the spinning head, cooled and solidified into silk strip, and continue to cool through the passage and finally wind forming. The polypropylene spinning machine is mainly composed of spinning control system, biphenyl boiler control system, winding machine control system and so on.
