Coal mine underground automatic drainage system is one of the four major parts of coal mine production. It is responsible for the important task of removing the underground water and is the guarantee for the safety production of the mine. Its quality is directly related to whether the mine can be safely produced. Underground drainage is not timely or fails. It may submerge the mine, causing the mine to stop production and causing major economic losses. Therefore, the safety and stability of the underground drainage system of the coal mine are related to the coal mine. Important Index of Safety 1. Composition of KXJ-127 Control Box The KXJ-127 mine explosion-proof control box is composed of: operation layer (touch screen), control layer (PLC), shell (mining explosion-proof enclosure) and voice prompt system. The control system is used to realize the automatic control of the drainage system. The friendly and intuitive touch screen realizes the man-machine dialogue and remote operation monitoring functions. The PLC controls the completion of the logic processing control tasks.
2. Main advantages of KXJ-127 mine explosion-proof programmable control box (1) Safety The shell of KXJ-127 is made of explosion-proof enclosure for mining. The intrinsically safe terminal block developed by the company is used inside the enclosure to effectively control the voltage. Within the safety range, the signal will be sent to the voice board when the equipment is running and stopped. The voice prompts will be provided before the pump action. The safety is higher (2) The reliability is high. The anti-jamming capability is strong The internal control box of the KXJ-127 adopts Siemens PLC control. , With high reliability and anti-jamming capability, will not appear in the relay-contactor control system wiring aging, off welding, electric arc and other phenomena, known as "computer designed to adapt to harsh industrial environments"
(3) Flexible and general-purpose PLC realizes the control through the program in the memory. If the control function needs to be changed, only the program and a few wirings can be modified. The same device can be used for different control objects, and different controls can be realized by modifying the software. The control requirements (4) are simple, intuitive and convenient KXJ-127 control box remote, local two operating modes. The on-site data acquisition via the touch screen enables better feedback on the operation of the equipment. At the same time, the fault records during operation can be observed. The operation is simple and more intuitive. (5) The wiring is simple. The KXJ-127 explosion-proof programmable control box requires only input devices. (such as buttons, switches, etc.) Connect to the input terminals and connect output devices (such as contactors, solenoid valves, etc.) to the output terminals. The wiring is extremely simple and the workload is small. (6) Small size, light weight and low power consumption 3. Conclusion After the KXJ-127 coal mine explosion-proof control box system is put into operation, the pumping house drainage system operates more safely and reliably, and the operation is more convenient and concise. And effectively extend the service life of the pump, improve the drainage capacity of the mine, reduce the accident rate, reduce the troubleshooting time, extend the service life of the equipment, improve the economic and social benefits of the mine, and thus provide security for the mine's safe production.
