1 electrical working principle of compact tension machine
Basic principle of xK a 1 type of automatic small tension machine working electrical principle block diagram. Work, debugging first display to a value of zero, and pre tensile test extension piece a, start signal, voltage signal by the sensor output, the first to enter the filter to filter out all the spikes and AC interference, into the amplifier amplification, the output of the digital signal display Weili value. Since the start of the motor rotation encoding disk that is to work, encoding disk with 5O through the hole is the formation of a binary cycle code. Photoelectric encoding is a high precision shaft angle into the encoding electric signal, that is, by the optical conversion method to the corresponding number (length). Control system according to the preset pulse value (pulse conversion length) to control the action of the relay, so that the motor rotation or stop working.
Technical performance:
Load: 3ON ~ O, frequency: 50Hz, accuracy: 2 * 10-2N, resolution: 1 / 2 (200 * 10 N), 10,, 220V 1999, 40toni, 7O, 5O, 1O0, 3O,,,,, two.
