Rotary Kiln circuit design allows a start circuit during operation but is easy to

encounter some problems. After rotary kiln electrical circuit fault analysis

understanding. We need regular checks in the daily operation of the rotary

kiln electric circuit rheostat level, temperature is normal, check the wiring

connection is intact, the contact is close; various types of contactors,

relays contact spring pressure is normal, whether the location of each trip

switch accurate, etc.; sometimes a fixed position limit switch contact closure

will cause improper insufficiency disorders, no detail could be the source of

the problem, so we must do the inspection rules, in order to ensure the

production of safe conduct. Kiln there had been started after the end of the

rotor shorting contactor is not timely closed, resulting in long-term power

rheostat, the motor speed drop occurs, and the boiling temperature of

electrolyte, sodium carbonate solution overflow outside the box turned into

foam and other accidents, we should start from shorting contactor control

secondary control loop to start solving. There is a circuit design allows the

boot loop, only when the internal and external conditions, such as electro-

hydraulic circuit all the liquid level, temperature is normal; electrical

components of the circuit involved and more, prevent low level or high

temperature rheostat working temperature, liquid level etc. Relays; prevent

starting the motor contactor class shorting the main rotor state; has a

control electrode running up and down limit switch; There are some safety

systems to be provided in the double-throw knife into the camera and limit

switches Other electrical contacts on the needs of the chain and so on.
