Tianjin Bernard electric actuator manufacturer Mai Weifu experts to answer:
(1) Check the connection of Bernard's electric actuator amplifier to the motor. If one of them breaks, this appearance will be presented;
(2) When the polarity of the Bernard actuator input signal changes, the two flip-flops should have alternating pulses. If there is no pulse on one side, there are: 1. Crystal transistor breakdown; 2. Single-junction transistor BT31F breaks or breaks down; thyristor does not turn on when there is no pulse at the moment; 3. If both trigger outputs are normal, maybe Controlled silicon damage; 4, servo motor damage.
How Bernard Electric Actuators View Experiments?
A: Wiring according to the instructions of the Majestic Bernard Electric Actuator;
(1) Combine the power switch "1K", place the motor "handle" in the manual position, and swing the handwheel to make the output go to the zero position of the valve actuator;
(2) Make the Bernard electric actuator at the high end of the cam. At this moment, the milliammeter indication should be 4MA;
(3) The Tianjin Bernard actuator swings the handwheel so that the output shaft rotates clockwise by 90 degrees. The milliammeter indication should change from 4 to 20 MA accordingly. If the valve electric actuator is less than (or exceeds) 20MA, the position transmitter cover can be opened, the potentiometer can be adjusted, and the output current of the rotation angle and position transmitter should be in one-to-one correspondence.
(4) The operation button "2K" output shaft should rotate clockwise. The operation button "3K" output shaft should rotate counterclockwise. At the same time, the output current of the position transmitter should be able to correspond to the rotation angle.
It is hoped that the above proposal is useful for customers who buy Bernard electric actuators. Customers must provide specific and reliable parameters when selecting electric actuators. Electric actuator manufacturers can report accurate electric actuator models, and the customers are in use. Be sure to study the Bernard electric actuator instructions.
Intelligent Bernard electric actuator is Tianjin Maifufu Bernard Electric Actuator Co., Ltd. combined with today's microelectronics technology, electronics, power devices successfully design a new generation of electromechanical integration products, intelligent electric actuators, able to adapt to today's many A variety of complex control system requirements, and provide a variety of different electric actuator model products for the actual function of the control system engineering. The Bernard electric actuator can only work in one direction, and the actuator does not move when the polarity of the input signal changes. What is the reason?
