What should we pay attention to in the running process of polypropylene spinning machine?

1. The transmission part of polypropylene spinning machine should run smoothly and without abnormal sound.

2, polypropylene spinning machine under normal working conditions, screw extruder gear box surface temperature rise should not exceed 30℃. Metering pump gearbox temperature rise should not exceed 20℃.

3. When the ambient temperature of polypropylene spinning machine is lower than 28℃, the average temperature value of the front and rear surface of the spinning box insulation layer should not be greater than 65℃.

4. The pipe connection of polypropylene spinning machine shall not leak.

5. The wind speed of the blowing device should be stable, and the wire cambodians should have no violent swaying or wire parallel phenomenon. In the ring blowing device, the wind speed difference rate of single spinning position on the same horizontal plane shall be no more than 15, and in the side blowing device, the wind speed difference rate of single spinning position on the same horizontal plane shall be no more than 20.

6, the wire bundle channel and the wire bundle contact part should be smooth, no wire hanging.

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 temperature and pressure signals in the field. Each spinning position on site is equipped with a button box. The start and stop of the metering pump and the agent pump are controlled by the button on site, so the enabling signal of frequency conversion is generally given by the terminal.

Because metering pump and oil pump are synchronous motor, so the frequency conversion only needs the general open-loop control. The difference between metering pump and oil pump is that metering pump is usually driven by frequency converter, while oil pump is driven by frequency converter.
