The brake in the actual operation, proved to be feasible. Small size, low power consumption, current adjustment, easy to operate, saving, saving, and reliable operation. Braking energy to overcome the traditional shortcomings of the way, can be modified directly in the explosion-proof switches. This device combines a large SCR speed control system braking advantages, but the structure and is relatively simple, so. Has promotional value.
General plant basic mechanical brake braking centrifuge. On the centrifuge, the motor just cut off the power, speed fast, inertia, brake for a smooth, braking more difficult. According to production requirements, the motor is turned off, let the centrifuge rotation 1O minutes, until the speed dropped to low, began to mechanical braking until stopped so need a long time to affect production if the operator has just cut off the motor power to mechanical brake on the centrifuge, the braking time can be shortened, but rubber brake pads replaced frequently, it will affect production, but also increased the mechanic's workload. Centrifugal brake until the centrifuge clutch disengaged, motor stops so far. At this point, the centrifuge speed is very slow, then the mechanical brake. This can shorten the braking time and reduce operating strength, but also the time delay for brake pads. In the test run, the entire time can be shortened by 2 / 3, brake smoothly, easy to operate.
Therefore, the ideal is: power is cut off, otherwise the motor before the brake, it is better to use braking, because braking energy loss is small, smooth braking, especially for. |
