Traditional electric heating method:
1. On the one hand, it is the measurement error of the temperature sensor, on the other hand, the electric heating is concentrated and the temperature is uneven.
2. If the temperature control is abnormal, it will easily lead to serious accidents such as unqualified fan blade products, scrapped blades, burning and carbonization of FRP internal structure of fan blade mold, and fire of fan blade mold.
3. The disadvantage of heating with electric heating wire is that the mold is not evenly heated. If the electric heating wire is burnt out, it will be difficult to detect the group of electric heating wires burnt out, which will greatly affect the production progress.
Temperature control method of water temperature machine;
1. Wind turbine blade mold with water circulation temperature control system can minimize this error.
2. Through water circulation heating, the cavity temperature and the target temperature are kept within 0.5℃, and the overshoot of the system is very small due to indirect heat transfer.
3.PLC touch screen control system can display the dynamic flow chart of heating and cooling system in real time, which is used to display and adjust the technical parameters such as equipment temperature and time.
