Nowadays, there are more combined equipment used in explosion-proof places to achieve more complex functions. In view of the explosion-proof certification technical requirements of this type of equipment, Zhongnuo Testing has summarized many years of industry experience, mainly including the following points:
1) The explosion-proof performance only considers the electrical part, the installation and connection between the electrical, the grounding, etc., and does not consider the steel structure part.
2) Electrical components are required to be purchased and installed with explosion-proof certificates or explosion-proof 3C certificates. If you can't buy suitable explosion-proof electrical parts, you can consider using flameproof positive pressure and other ways to install them.
3) The explosion-proof mark of the selected explosion-proof electrical components should not be lower than the explosion-proof mark level of the whole machine.
4) The installation, electrical connection and grounding of explosion-proof electrical components should meet the requirements of the standard.
In terms of combined equipment forensics, Zhongnuo Testing has a professional technical team and industry experience, which can provide explosion-proof design guidance such as positive pressure and flameproofing, guide customers to select, install, and prepare drawings for electrical equipment, and can also appoint engineers for on-site testing to reduce customers' forensics costs and time costs. Successful forensics cases include robots, a** trolleys, industrial ovens, high and low temperature boxes, hydrogen refueling machines, filling machines, skid-mounted refueling devices, chemical storage cabinets, dust removal equipment, etc. If you have any needs in this regard, please send us a private message for further communication.
