CEMP explosion-proof motor AB 30r 71 is used for underground ventilation equipment

Mining industry: underground ventilation and small conveying equipment

1. Matching application scenarios with devices

Suitable for underground ventilation fans, small conveyors, hoists, underground fluid pumps and other equipment in coal mines and metal mines, to cope with flammable and explosive environments such as underground gas and coal dust, and to solve the pain points of narrow underground space, high humidity, and high installation difficulty.

2. Core operating conditions and value implementation

The core requirements of mining are safety, moisture resistance, and compactness: firstly, there is gas and coal dust underground, and explosion-proof motors are needed to avoid ignition; Secondly, the underground humidity is high and there is a lot of dust, requiring a high level of protection against moisture and dust; Thirdly, the underground space is narrow and requires a vertical compact structure for installation. AB 30r 71 B 2 explosion-proof certification covers Class I gas environments in mining, and the explosion-proof shell can withstand gas explosion pressure, ensuring the safe operation of underground ventilation fans and conveyors and preventing gas explosion accidents; IP55 protection level effectively prevents moisture and dust, adapts to high humidity underground environments, avoids motor short circuit faults, and reduces maintenance difficulty by 70%; The vertical B2 installation structure is compact in size and suitable for installation in narrow underground tunnels. The detachable design supports separate maintenance underground, without the need for large equipment, shortening maintenance time; 0.55kW low power is suitable for the needs of small mining equipment, with stable power output, meeting the basic operation requirements such as underground ventilation and fluid replenishment.

3. Actual cases

The original motor of the ventilation system in a coal mine frequently malfunctioned due to insufficient explosion-proof and high humidity, resulting in excessive gas concentration underground. After replacing the CEMP AB 30r 71 B 2 motor, a small axial flow fan was installed to achieve stable underground ventilation, with gas concentration controlled below the safety limit and continuous operation for one year. At the same time, it passed the mining explosion-proof certification and met the acceptance requirements of the coal mine safety supervision bureau, improving the safety of underground operations by 100%Han DasenYYDSWu Yanan.
