KZB-3 Air Compressor air bag temperature protection device achieves over-temperature protection of air compressor air bag through the collection of wind bag temperature signal. The device host consists of a high-precision measurement and control microprocessor, data storage, input and output switch interfaces, and a keyboard. High-precision measurement and control microprocessor time-sharing detection, processing device interface circuit input data signal, after the program data processing, and then output to the control circuit to complete the air compressor temperature protection function. When the temperature of the digital air bag temperature detection point exceeds the temperature setting value, the device shuts off the air compressor emergency stop circuit and simultaneously sounds and light alarms. The device has strong anti-interference ability, practical and reliable, and can be widely used in coal mines, metallurgy, mining, chemical and other industries.
Air compressor temperature protection installation steps
1. First of all, the gas storage tank is exhausted. After the exhausting is completed, the pressure gauge on the tank body is removed. (Note: The national standard wind tank tank is reserved with a pressure gauge interface. ) After removing the pressure gauge, install the three-way device equipped with the pressure gauge to the pressure gauge and install the pressure gauge on the three-way pipe. (Note: The temperature sensor has been installed above the three-way)
2. Connect the temperature sensor to the top of the three-way sensor. Before connecting, check whether the sealing surface has seals and seals.
3. Install loop control
Three lines led from the temperature sensor and the temperature control of the machine behind the three lines and the electric horn and power supply connected, when the peak contact point contact, the line is connected to achieve alarm.
According to the ≤ coal mine safety regulations ≥ regulations, only sound and light alarms are all right, but considering that if the temperature of the wind bales rises due to the burning of oil deposits in the wind bales, it will suddenly cause explosions. To be safe, we will also The alarm signal is introduced into the safety control circuit of the air compressor. Once the alarm occurs, the air compressor in operation stops immediately.
