220V explosion-proof electric actuators have functions such as internal servo operation and opening signal position feedback, position indication, manual operation, etc., with strong functions, reliable performance and simple wiring. The rotation angle of the core can be changed by inputting current or voltage signals. The proportional adjustment action is realized, the channel is flat and smooth, it is not easy to deposit media, and the pipeline pass ball can be used. The structure is simple, the weight is light, and the sealing performance is good. 220V explosion-proof electric actuator adopts high-strength glass lens sintering process, the opening window is more beautiful and smooth, and the electrical limit stroke position makes the electrical limit adjustment easier and more accurate.
The green wire is connected to any one of the three sets of wires that the controller outputs to the motor. The purpose is to detect whether the motor is rotating. It is a signal output line that locks the motor. If the line is blue, it means that the anti-theft device is a low-potential version That is, the line has zero voltage and is connected to the ground during an alarm. If the line is purple, it means that the immobilizer is a high-potential version, that is, the line voltage is 5V when the alarm is issued. The 220V explosion-proof electric actuator pneumatic valve needs to be equipped with air source facilities such as an air compressor station. It is a sucking scanner that rotates and moves up and down. The sucking scanner is internally connected to a 3 ”sewage valve. When the sewage valve is opened, the water inside the filter The pressure difference between the pressure and the external atmosphere creates a strong suction force for each nozzle. The scanner sucks the impurities from the filter and discharges them through the drain valve. This cleaning process takes about 35-60 seconds. The four filters of the filter The nets are cleaned in turn. During the entire anti-cleaning process, the system continuously flows.
