Flameproof and intrinsically safe electric control box for mine

Flameproof and inherent safety type programmable electric control box for mine is suitable for underground coal mine with explosive dangerous gas and coal dust, mainly used in underground coal mine small pump control, belt transport control, crusher control, emulsion ratio control, coal slime water treatment control, automatic loading machine control, hopper weighing ratio control and other automatic control devices. Using imported programmable controller (PLC) as the core equipment, it has strong applicability, scalability, high reliability and strong communication ability. Its logic control mode can be realized by software programming, which makes the complex control logic simple and easy. There are reliable isolation measures and intrinsic safety power supplies between the input and output signals inside the control box, thus ensuring more flexible and universal connection and matching with various types of sensor actuators and various equipment electronic control circuits.

DESCRIPTION

Product use

Flameproof and inherent safety type programmable electric control box for mine is suitable for underground coal mine with explosive dangerous gas and coal dust, mainly used in underground coal mine small pump control, belt transport control, crusher control, emulsion ratio control, coal slime water treatment control, automatic loading machine control, hopper weighing ratio control and other automatic control devices. Using imported programmable controller (PLC) as the core equipment, it has strong applicability, scalability, high reliability and strong communication ability. Its logic control mode can be realized by software programming, which makes the complex control logic simple and easy. There are reliable isolation measures and intrinsic safety power supplies between the input and output signals inside the control box, thus ensuring more flexible and universal connection and matching with various types of sensor actuators and various equipment electronic control circuits.

Main feature

Perfect structure design: translation type quick opening structure, drawer type movement, easy installation and maintenance;

Stable and reliable performance: high-performance PLC processors, industrial isolation terminals, etc.

Safe power supply and non-safe power supply, communication interface high-speed photoelectric isolation, to ensure the control box stable and reliable work;

7 inch high brightness TFT LCD screen, full Chinese multimedia interface, real-time measurement and display system voltage, current, fault status, sensor parameters;

Menu operation, with online query, modify technical parameters and other functions;

All analog signals are processed as digital signals, with strong anti-interference ability, simple wiring, large amount of information, reliable and accurate control characteristics; The output circuits are equipped with independent functions such as short circuit, overload, phase break, over and under voltage, leakage lock, pilot protection, fault self-diagnosis, contactor bonding, fault memory, etc. At the same time has the fault shielding function;

The electric control box can be selected with mine liquid level sensor, temperature sensor, pressure sensor, speed sensor, radar level sensor, vibration sensor, flow sensor, weighing sensor and other equipment to achieve different customized functions;

Equipped with water level detection control device and water level probe, can set high, middle and low water level to achieve automatic drainage function, especially suitable for centralized control and protection of several small pumps;

The mine speed sensor can be used to protect the crusher. Realize the forward and reverse control of the traveling motor; Automatic filling of lubricating oil pump; Hydraulic cylinder advance control, etc.;

Equipped with mine position and speed sensor, it can realize a series of functions, such as automatic control, transfer and conveying control, etc., and has a high degree of mechanization, which can realize automatic continuous operation.

The mine flow sensor can realize the automatic treatment of slime water, and collect and analyze the flow of the pipeline.

The automatic batching control system can be realized by configuring the weighing sensor for mine. The belt or batching screw can be used as the conveying tool to control the proportion of bulk materials and manage various data in the production process according to user requirements.

The configuration of mine flow sensor, water level sensor, proportional flow valve and electric ball valve can realize the automatic control function of emulsion ratio, directly display the concentration and flow, and provide a stable working medium for hydraulic support and other equipment;

Electric control box with Ethernet, optical fiber transmission function;

The intelligent control is realized by using industry standard CAN bus or RS485 field bus technology for serial communication.
