Description
 Extrusion granulation equipment maintenance
Customer: Shenzhen City, Pinghu Mugumou plastic products company
Equipment name: Nanjing Norda extrusion equipment
Equipment failure: the main motor does not run
Failure analysis: the working principle of twin screw extruder
A, parameters are: engine speed, feeding speed, main current, cutting speed, melt pressure, melt temperature, temperature section and so on
B, the engine speed and the current is not directly related, but the higher the speed, the power loss will be more economical.
C, by feeding half starved feeding, so feeding is directly related to the extrusion production capacity.
D, melt temperature is the basic material of the actual temperature; section temperature and the actual temperature difference between the material, the general difference 5~20 degrees. This is because of the difference between the probe and the material.
E, the host speed, feeding speed and temperature setting section optimal matching and balance, in order to maximize the efficiency of extrusion, realize high quality and high yield of the product. (at the same time consider the combination of screw elements).
PVC resin, weighing, mixing, cooling and mixing speed, twin-screw extruder, cooling, various additives single screw extruder, traction, cutting, packaging, extrusion products
From the working principle of the main motor does not run the main inverter control, the frequency of operation of the inverter signal and frequency is mainly controlled by the OMRON PLC, according to the operation of the PLC part of the signal is normal. Frequency converter in the start of the operation of overheating alarm, the initial suspect is the cause of damage to the inverter. It is found that the internal dust is much more in the examination of frequency converter. After the inverter to clean up the internal power found on the inverter fan is not running. After a long time to replace the normal operation. Fault release.
