Tianjin Bernard electric actuator manufacturers commissioning work

/ March 14, 2020

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?

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.

Brandt Shaker Screen

Brandt  Shaker Screen  models:  Brandt King Cobra Shaker Screen, Brandt VSM300 (Primary, Scalping, Secondary) Shaker screen,Brandt BLT-50/LCM-20 shaker screen, Brandt 4'X5' Shaker Screen, Brandt Hybrid shaker screen,  Brandt D285P Shaker Screen.

Brandt  Shaker Screen types also  includings  steel frame shaker screen and composite frame shaker screen.

1).  Steel frame shaker screen main feature as follows:

  1. These products screen panels are constructed with two or three 304 or 316 stainless steel wire cloth layers with s steel backing plate and steel frame combined together. Because of different mesh size and hole size, get an better filtering effect.
  2. The bottom high strength steel frame, supporting bar with the moderate tension screen cloth, combined together, infinitely enhance the screen intensity and endurance, get an better filtering effective. Mesh sizes ranging from 20to 325. The whole cloth is divided into independent small surfaces, prevent the part excessive expansion damaged, with a special rubber plug together to repair damage, can save the time to replace the screen, Increase the efficiency and reduce the cost.

2) Compoiste Frame Shaker Screen is made by polyurethane material frame with two or three layers 304 or 316 Stainless steel wire cloth, Main feature as follows.
  1. High strength plastic frame and moderate tension screen cloth that from a reliable whole, greatly enhance the tolerable.
  2. The screen is divided into several independent small cloths to pervent excessive expansion of local damage.At the same time, With a special rubber plug to repair damage, it can save time and reduce use-cost.
  3. Rapid wedge tensioning devices make screen installation more convenient, and save the time of machine half for changing.
  4. Excellent polyurethane material frame enhance corrosion resistance, have a good stock absorption and ectend working life of screen
