KZB-PC Type Air Compressor Oil Cut-off (Integrated) Protection Device

It can be used wherever there is an air compressor and is widely applied in the safety protection of self-rescue systems in coal mines and non-coal mines. Its main functions include air compressor oil and water cutoff protection, anti-coking and anti-seizing patents, oil level monitoring, as well as overtemperature and overpressure protection for air storage tanks. It features a reserved IoT interface, allowing real-time upload of operational status to mobile devices and remote computers for monitoring. With an upload interface, it can be integrated into unattended systems, saving costs.

This device can be widely used for safety protection in compressed air self-rescue systems in coal mines and non-coal mines.

The device is developed using advanced sensing detection technology, industrial control technology, and microcomputer control technology. It boasts high intelligence, comprehensive monitoring, high reliability, advanced craftsmanship, energy efficiency, environmental friendliness, low power consumption, and ultra-convenient maintenance. It completely prevents damage failures such as oil coking and compressor head seizing caused by oil or water cutoff in air compressors.

II. Design Basis

Article 432 of the 2016 edition of the "Coal Mine Safety Regulations" (Equipment in Air Compressor Stations Must Meet the Following Requirements), Clause 3 stipulates:

Oil-lubricated air compressors must be equipped with oil cutoff protection devices or oil cutoff signal display devices. Water-cooled air compressors must be equipped with water cutoff protection devices or water cutoff signal display devices.

III. Main Functions

1. Air compressor oil or water cutoff protection (patented anti-coking and anti-seizing technology)

2. Air compressor oil level monitoring function

3. Temperature and vibration monitoring of the motor and main bearings

4. Overtemperature and overpressure protection for air storage tanks

5. Intelligent reminder function for oil filter replacement

6. Reserved IoT interface, allowing real-time upload of operational status to mobile devices and remote computers for monitoring. Through multi-level permission settings, remote control of air compressor startup and shutdown can be achieved within the scope of permissions.

7. Enables centralized remote monitoring and unattended operation of ground air compressors.

8. Equipped with an upload interface, it can serve as a front-end sampling device and be integrated into unattended systems, avoiding redundant investment.
