How to adjust the stroke of the pneumatic actuator?
The pneumatic actuator has the characteristics of simple design and compact structure. Pneumatic actuator series products up to 15 kinds, can be customized according to user needs, add a variety of functional configuration, to meet the control requirements in the production process. Of course, if you want to make better use of pneumatic actuators, it is very important to adjust your itinerary. So how to adjust? Here is the introduction.
Pneumatic actuator stroke debugging method:
1. Adjust the zero position first, and the pressure gauge on the locator 4mADC locator is 0.004MPa(not more than 0.004MPa);
2. Look at the full scale, give the positioner a 20 mADC positioner pressure gauge of 0.2mpa, if the pressure is less than 0.2MP, if the pressure gauge exceeds 0, adjust the range knob, turn counterclockwise to increase the range, 2MPa if too much, turn clockwise to reduce the range.
3. Repeat step 1, 2, make the locator stroke in conformity with the valve stroke, 4, mADC. 12 mADC. 16 mADC. 20 madc5:4 journey shall be the average length.
Of course, in addition to adjusting the stroke, but also do a good job of valve position debugging, the following is the valve position debugging method of Aisheng pneumatic actuator:
Given a 4mA instruction signal, press and hold the setting key until the module indicator lights up and flashes, that is, the debugging state is entered. Observe that the reading of the ammeter should be 4mA. If there is any deviation, press "+" and "-" to adjust it to meet the requirements. Then press the set button to confirm. At this time, the ammeter reading should be 8mA. If not, you can press "+, -" to adjust the button and give 8mA command signal. By analogy, adjust 8mA, 12mA, 16mA, 20mA respectively. After the adjustment of 20mA, the indicator light will blink several times, indicating that the debugging has been completed.
