What precautions should be taken when using explosion-proof vacuum cleaners in hazardous areas?

The working principle of explosion-proof vacuum cleaners is similar to that of ordinary vacuum cleaners. Both utilize the suction generated by the motor during operation to create negative pressure inside the sealed body and pipelines, thereby drawing dust, iron chips, wood chips, and liquids such as water from the ground or equipment into the dust collection barrel inside the machine, aiding in cleaning operations across various environments. The key difference lies in the special requirements for design and production of explosion-proof vacuum cleaners. For instance, in design, intrinsic explosion-proof or flameproof methods may be employed. In production, main components should either be explosion-proof or isolated if non-explosion-proof, such as using explosion-proof motors or applying explosion-proof isolation (i.e., flameproof treatment) to them. Electrical boxes are typically explosion-proof enclosures. Additionally, explosion-proof vacuum cleaners generally feature metal casings and metal barrels, with high-end models using stringent explosion-proof stainless steel. Hoses and nozzles are made of metal or conductive materials, or at least anti-static materials. Due to these stringent safety requirements, explosion-proof vacuum cleaners are widely used in chemical, pharmaceutical, metal processing (especially where metal powder is generated), tobacco factories, power plants, flour, milk powder, and other hazardous environments.

When using explosion-proof vacuum cleaners, the following precautions are essential to ensure operational safety:
1. Understand and use vacuum cleaners with explosion-proof ratings that meet or exceed the requirements of the hazardous area. For example, Zone 1 areas must use Zone 1 or Zone 0 explosion-proof vacuum cleaners, while Zone 2 areas can use Zone 2, Zone 1, or Zone 0 models. Additionally, for gas explosion-prone or dust explosion-prone environments, use gas explosion-proof or dust explosion-proof vacuum cleaners accordingly, and avoid using the wrong type. All explosion-proof vacuum cleaners must be properly grounded.
2. Select the appropriate specifications: Similar to ordinary vacuum cleaners, explosion-proof models are categorized by power, air flow, suction, etc., and differ in motor types. Choose the suitable motor type and power based on the specific requirements of the environment. In terms of air flow and suction, even vacuum cleaners with the same motor power may vary; some prioritize high air flow for central vacuum systems, while others focus on strong suction for collecting heavy objects. These factors should be considered before use.

3. Strictly adhere to safety regulations and operating instructions: Explosion-proof vacuum cleaners come with detailed user manuals that outline safety norms and specific operations. Ensure operators receive proper training and follow these guidelines meticulously to avoid damaging the machine or reducing its lifespan.
4. Perform regular maintenance: Explosion-proof vacuum cleaners require periodic inspections and upkeep, such as checking for loose connections before use, cleaning the machine after daily operation, regularly cleaning filters, and replacing worn or damaged parts.
5. In case of malfunction, seek assistance from the manufacturer or supplier. If necessary, request on-site repair services. Avoid self-repair to prevent damage to the machine or personnel. For parts replacement, use genuine components to ensure compatibility and avoid potential adverse effects from inferior parts.
In summary, due to the特殊性 of their operating environments, it is crucial to remain vigilant and prioritize safety when using explosion-proof vacuum cleaners.
