Jiuquan pneumatic damper automatic control device - mine damper automatic control device

Jiuquan pneumatic damper automatic control device mine air damper automatic control device mine traveling crane automatic balance non pressure air damper and mine pedestrian full automatic front and reverse air damper are both assembled by the air damper body and the air damper automatic control device into a whole to play a role. The automatic control device of pneumatic damper is different from hydraulic and electric ones. It is driven by high-pressure gas, so it is named. 3. The device uses infrared (target) sensor, detection range: * * * 6m4, sound: sound level intensity: greater than or equal to 80 {db (a)} 5, light: light visible distance * * 20m6, control function: when the input is high level * * * 5v, the output of the control box is low level 0~5v, when the input is low level ≤ 1v, the output of the control box is high level 24 ± 0.5v.

The automatic control device of pneumatic damper The electrically controlled pneumatic automatic damper can be used underground as the carrier of the remote full-automatic control damper. The purely pneumatic automatic damper cannot be connected with the remote full-automatic control, so it is impossible to use this matching device. Especially when the ordinary automatic damper underground is transformed into the remote full-automatic control damper, pay attention to this point. 7. Interlocking function: electrical interlock can be realized between the two devices to prevent two dampers from being opened at the same time. 8. Button control: two switch buttons are set to manually control the opening and closing status of the air door, a button controls the opening and closing status of door a, and b button controls the opening and closing status of door b. When door a is opened, the acousto-optic device triggers and sends out the warning message "Open the air door, please pay attention to safety" and the red light flashes. At the same time, the acousto-optic device of door b prompts "Open the front air door, please wait" and the red light lights up.

Automatic control device of pneumatic damper Performance characteristics

1. The device is automatically controlled by plc, uses infrared sensor as a device, and has language, so pedestrians and vehicles can pass smoothly and safely.

2. Control function: after receiving the infrared sensor, the controller will control the cylinder and oil cylinder of the actuator and open the air valve; 7 seconds later, it can be adjusted by plc to automatically control the actuator and close the damper.

3. Locking function: when any one of the two interlocked air valves is opened, the controller controls the actuator to lock the other air valve so that it cannot be opened; When the opening damper is closed, the controller will automatically unlock.

4. Manual unlocking function: when a fault occurs, press the reset button, the whole control stops working, and the damper can be pushed open manually. After troubleshooting, press the set button, and the control will resume normal operation.

5. Prompt function: when the damper is opened, the controller shall control the sound light box prompt.

Pneumatic damper automatic control device damper, transmission mechanism respectively set on two opposite door frames, a lock box is set between the two door frames, two heavy hammers such as the one that can rise and fall alternately or at the same time are set in the lock box, the two heavy hammers are respectively connected to the transmission mechanism through steel wire ropes, and between the two heavy hammers is a lock failure cylinder fixed on the lock box, The push rod of the failed locking cylinder is provided with a triangular locking block that can be locked alternately by two heavy weights, and the locking block is connected with the locking box. In this embodiment, the working pressure of the air source in the air source processing box 14 is 0.3-0.8mpa. Air door full pneumatic switch control device | Full pneumatic door opening and closing device 2. When or when passing a car, door a opens automatically and door b closes; After people or vehicles pass through door a, door a will automatically close and door b will automatically open, accompanied by sound and light well alarm prompt. In this embodiment, the working pressure of the air source in the air source processing box 14 is 0.3-0.8mpa. Air door full pneumatic switch control device | Full pneumatic door opening and closing device 2. When or when passing a car, door a opens automatically and door b closes; After people or vehicles pass through door a, door a will automatically close and door b will automatically open, accompanied by sound and light well alarm prompt.
