What are the heating methods suitable for a polypropylene spinning machine? The heating of a polypropylene spinning machine needs requires an electromagnetic heater that is the main component of the machine being a hot roller, which can be heated to a certain temperature and is running at high speed.

The size of the hot roller is different, and generally there is a diameter φ160 φ180 φ190 φ210 φ220. Thermal roller length: 200-450mm, the speed range is: 750-5500m / min, the surface temperature of the guide wire: ≤ 240 ° C-140 ° C, the surface of the hot roller is treated: colloidal chromium, ceramic.

The hot roller now heating is a power frequency induction heating. Its disadvantage is that the heat generator is easily damaged. It is terrible to heat the center shaft of the motor to burn the motor. However, the newly developed all-digital applies to the polypropylene spinning machine heat roller heating efficient energy saving, effectively solving the shortcomings of traditional heating, greatly reduces costs. Its main advantages are:

1. The surface temperature of the heat roller workspace is uniform, which can meet the requirements of different industrial silk, civilian wire FDY spinning process.

2. The surface temperature of the thermal roller workspace is rapid, and the energy saving is obvious, and the efficiency is greatly improved.

3. After using the electromagnetic heater, the shaft of the heat roller motor does not damage the motor due to induction heating.

4. The coil of the electromagnetic heater will not be damaged and reduce the trouble and cost of maintenance.

5. The equipment system is perfect, the structure is simple, and the operation is smooth and reliable at high temperatures, which can meet the requirements of different fiber FDY spinning processes.It is a reasonable choice for the economy of polypropylene spinning machine.
