With the improvement of people's awareness of production safety, in order to ensure production safety and protect the safety of life and property, most electrical equipment used in industry has been replaced with explosion-proof equipment. However, people often ignore the electric sparks generated by electric drills, grinding wheels and other equipment, and the electric sparks generated in the fire ban area should not be ignored. 

1. Accident case:

   In the "5.12" explosion accident of Shanghai Secco Petrochemical Company, a non industrial electric drill was used in a benzene storage tank. The electric drill spark detonated the benzene vapor in the tank, directly causing the death of 6 people working in the tank. GB30871-2022 "Safety Management Specifications for Special Operations of Hazardous Chemicals" has included operations using electric drills, grinding wheels, etc. in fire ban areas as hot work. Hot work is very likely to cause fires because these tools will generate sparks and high temperatures during work, which may cause fires, explosions or other thermal decomposition reactions. Therefore, in production, the explosion-proof performance of tools used in hot work cannot be ignored.

2. Industrial electric drill:

   The structure of the Industrial electric drill includes handheld, motor, drill bit and power supply.The handheld part adopts an ergonomically designed shape for easy operation; the motor part adopts a high-power motor, which is more durable, more powerful, and easy to drill. The high-quality motor creates a good core; the drill bit part can replace drill bits of different specifications, 20 gear torque adjustment, and one machine can handle multiple needs; the power supply part adopts a rechargeable lithium battery, which has the advantages of large capacity, long life, and light weight.

   The industrial electric drill is mainly used for drilling, opening holes, milling and other operations in flammable and explosive environments. It is a safety tool specially designed for hazardous environments, which can effectively prevent the generation of sparks or static electricity, thereby avoiding the detonation of flammable gases or dust. It is widely used in petrochemical, metallurgical, coal, oil, natural gas and chemical industries. Some industries have very high requirements for safe production, and the design and structure of the explosion-proof electric drill can meet these requirements, providing workers with a safe, efficient and convenient way of working.

3. Precautions:

   1. Before use, you must check whether the power supply is sufficient and whether the battery life is expired.

   2. Before use, you must check whether the drill bit is firm and whether it meets the operation requirements.

   3. During use, pay attention to keep the drill clean and sharp to avoid drilling jams and poor drilling quality.

   4. When used in flammable and explosive environments, explosion-proof cables and industrial plugs must be used.

   5. During use, pay attention to controlling the speed and pressure of the motor to avoid overloading and damaging the motor. In short, when purchasing an industrial electric drill, pay attention to the power and performance of the electric drill and check whether it has the 3C mark of the national mandatory certification.
