Troubleshooting of film blowing machine
The film blowing machine is mainly used to detect the film blowing feasibility of polymer materials, the colloidal condition in the materials, and the dispersion of colored dispersions, control mixtures and extrudates. However, many people don't know where the fault occurs during the experiment. Let me talk about the faults that will exist in the use of Baoding instrument experimental film blowing machine. Some of them are as follows:

1. Fault condition: the machine is not powered on
Possible causes: power supply line failure, leakage switch and power switch damage
Troubleshooting: ask the electrician to repair and replace the leakage switch and fuse of the same model;
2. No heating: because the heating plate is damaged, the thermostat has no output, and the ammeter is damaged; Therefore, replace the heating plate, replace the temperature controller of the same model, and replace the ammeter;
3. Motor does not rotate: the frequency converter is damaged and the relay is damaged; Therefore, replace the frequency converter and relay;
4. Winding motor does not rotate: winding power switch failure, DC speed regulating board failure; Replace the power switch and relay;
5. There is a deviation between the displayed temperature and the actual temperature: the temperature controller is not corrected and the temperature controller is not calculated automatically; Correct the SC value and start the automatic calculation thermostat at;
