KHP236-K-Z Mining Explosion proof and Intrinsic Safety Belt Conveyor Protection and Control Device Host

Overview
This protective device is suitable for working environments such as mining faces, transportation tunnels, underground car yards, belt conveyors, and coal storage yards with explosive gases (methane) and coal dust. Adopting advanced logic control circuits to detect and protect underground belt conveyors, including 8 protection functions such as speed, coal level, deviation, emergency stop, tearing, temperature, smoke, tension, etc. Equipped with dual motor control and brake function. Combined with the KXH127 mining explosion-proof and intrinsic safety language sound and light signal device produced by our company, it can achieve language alarm and signal communication for the entire belt.
Host function
1. The control, detection and protection functions are complete.
2. It has dynamic display functions for tension and speed;
By setting, speed and tension can be blocked.
3. Parameter settings are simple and fast, easy to install
Debugging and maintenance.
4. It has emergency testing function (commonly known as throw protection), and when the test button is pressed, all protections will not work.
Main technical parameters
1. Working voltage: AC127V (or 36V); Voltage fluctuation range: AC90-240V; Relay contact capacity: AC250V 5A;
2. Intrinsically safe output high open circuit voltage: DC12.3V;
3. Speed protection has inverse time limit characteristics. When the speed is 0, the delay is less than 4 seconds to stop. The low-speed protection value and high-speed protection value can be set within the range of 0-9.9m/s. The speed self-protection delay can be set within the range of 0-99s;
4. The protection range of the tension sensor is 0-9.9T, and the upper and lower limits of the tension can be set through the panel buttons. When the tension is between the upper and lower limit values, it is normal. When the tension exceeds the upper and lower limit ranges, the microcontroller outputs a tension protection signal, which drives the voice alarm circuit and the indicator circuit to give an alarm.
5. Centralized control quantity: 20 units.
