How to deal with the failure of veneer dryer

Faults of the board dryer are as follows: 1. Failure analysis of rotary granulator: the main engine current is unstable. Production reasons: uneven feed, main motor bearing damage or poor lubrication, no heating. Faulty heater or incorrect phase, incorrect screw adjusting pad, component interference. Treatment method: Troubleshooting, check the feeder, replace the bearing if necessary. Repair the main motor and replace the heater if necessary. Check whether each heater is working properly, pull out the screws to check the interference of the screws, and check the adjustment pad. 2. Failure analysis of rotary granulator: the main motor can not start. Cause: The starting sequence is wrong, check whether the fuse is burned out; Main motor thread problem; Linkage work related to the main motor.

Processing method: Start again according to the correct starting sequence, check the main motor circuit, and check the status of the interlocking device related to the main motor. If the oil pump does not open, check whether the lubricating oil pump starts. The motor cannot be turned on, turn off the main power supply and other air classifiers, start again 5 minutes later, the inverter induction power is not completed, check whether the emergency button is reset. 3. Failure analysis of rotary granulator: the head discharge is not smooth or blocked. Cause: poor plasticization of the material. The molecular weight distribution of the heater cross section does not work, or the plastic molecular weight distribution is wide. The operating temperature is set to low and unstable. Foreign bodies that do not melt easily may be present. Treatment method: Replace, check the heater if necessary, consult a technician if necessary. Verify the set temperature of each section; Increase the temperature setting value; Clean and inspect extrusion systems and heads. 4. Failure analysis of rotary granulator: the main starting current is too high. Reasons: large torque, lack of heating time, heater part does not work.

High temperature resistant cable for electromagnetic heating equipment. The high frequency and high voltage currents that change at high speed will pass through the coil to produce an alternating magnetic field with high speed changes. When the magnetic force line in the magnetic field passes through the magnetic conductive metal material, countless small vortices are generated in the metal body, so that the metal material itself can be heated at high speed to achieve the ideal heating effect. [2] Electromagnetic heating technology is a new type of high frequency heating technology. After scientific research and development of scientific research workers, the production of energy-saving and environmentally friendly high-frequency heating system, heating efficiency increased to 90% (up to 99.8%). According to the installation and testing of various plastic processing enterprises, the energy-saving and environmentally friendly high-frequency heating system is very obvious for plastic processing enterprises, and the power saving is 30% or 70%. It fully reflects the advantages of energy saving, saves a lot of electricity, improves production efficiency, improves the workshop environment of plastic processing enterprises, and directly reduces production costs.
