The mine automatic damper control device ZMK-127 can be used without electricity
What does the mine automatic damper control device ZMK-127 refer to? Generally, the non-pressure air door of the mine must be equipped with a locking device. The simple locking only realizes the air door interlock, but the automatic air door control device ZMK-127 not only realizes the air door interlock, but also realizes the voice alarm. That is, when a person or a miner is sensed, the damper can be opened automatically, and an alarm is also realized, so as to realize the function of closing the damper. Can the mine automatic damper control device ZMK-127 be used without power? Commonly used damper control systems include electrical control, electro-hydraulic control, and pure electric control. These three systems all need electricity, some only need electricity, and some need electricity to follow the air to realize the opening and closing of the air door and alarm. So are there any ones that don't use electricity? Mr. Li answered yes, the pure pneumatic damper control device can not only realize the automatic opening of the damper by induction, but also realize the alarm of the damper. All functions realized by the electric damper can be realized. However, electricity is not required.
Briefly introduce the introduction of a mine-used automatic damper control device ZMK-127:
I. Overview
It is suitable for fully automatic control of facilities such as double-leaf pressureless air doors, single-leaf air doors, air doors shared by pedestrians, vehicles or vehicles in coal mines, and can control two or three air doors. When pedestrians and mine cars pass by, the device realizes the automatic opening and closing of the air door. When the mine is out of power, reliable manpower opens and closes the damper.
2. Features
1. This device uses a PLC automatic control system, an infrared sensor, and a language alarm to ensure the smooth and safe passage of pedestrians and vehicles.
2. Control function: the controller receives the signal from the infrared sensor receiver, and after identification, it controls the actuator (cylinder, oil cylinder) to act and opens the air door; after a delay of 7 seconds (adjustable by PLC), the actuator is automatically controlled Action to close the damper.
3. Locking function: When any one of the two interlocking air doors is opened, the controller controls the actuator to lock the other air door so that it cannot be opened; when the open air door is closed, the controller automatically unlocks.
4. Manual unlocking function: When a fault occurs, press the reset button, the entire control system stops working, and the air door can be manually opened at this time. When the fault is eliminated, the set button is pressed, and the control system resumes normal operation.
5. Voice prompt function: When the damper is opened, the controller should control the sound and light alarm box to prompt the voice signal.
No matter what kind of air door automatic control device, He Lilong manufactures it, no matter it is simple or complex, we can conduct training, or arrange engineers on site to guide the installation. Everything is for the sake of customers and solve a series of problems
The JUK universal Screw Terminal Block series has the typical features which are decisive for practical applications:
l The universal foot allows the terminal blocks to be easily snapped onto the NS35 or NS32 DIN Rail with G shape.
l Closed screw guide holes ensure screwdriver operation perfect.
l For terminal block with different wire cross-sectional areas, complete accessories are available, such as end plates, partition plates, etc.
l Potential distribution achieved by fixed bridges in the terminal center or insertion bridges in the clamping space.
l Same shape and pitch Grounding Terminal Blocks as the JUK universal series.
l Adopt ZB marker strip system,achieve unified identification.
