Mill motor system control are concentrated in
1, the host, fans start control
This control system, the motor capacity greater than 30 KW The buck starts less than 30KW with direct start system fan with star delta starter, the host Yanbian triangle move.
Startup and normal operation of the star triangle connected by contact with time relay control circuit, automatic switching, and the user can adjust the start situation. Time relay of high-speed extension of time greater than 6 seconds, the user can adjust the start situation.
2, control, control of the feeder
Principle of the structure of the electromagnetic vibrating feeder, electric vibrator is one pair of particle orientation forced vibration system, connected by material bad fork armature of the composition, its hanging hold in the silo the bottom and the swimming gap was a free state may not have stuck or objects collide phenomenon, in order to avoid noise.
(1)electric vibrator machine installation, loosen the screws to locate the connection fork(on three), loosen the nut tighten, open the back cover of the electric vibration, check the core and the convergence of the gap should within 1.8 to 2.1 mm, and the two should be equal clean, the screws should be tightened, the final will cover mounted on the fixed.
(2)whether the power load test, the electrical control box tune the amplitude of the potentiometer R, gradually increased by small amplitude should be between 1.8 and 2.5 mm, current 1.2 An amplitude of current work continuously for more than a few hours as table, normal feeding open hopper gate to observe the feeding current is stable, allowing the amplitude decreased 0.5 mm, such as amplitude currents were rated not yet meet the feeding requirements, would vibrators hoisting tilt angle, so that it satisfies the feeding quantity requirements.
