There are now many combination devices used in explosion-proof areas to achieve more complex functions. In response to the explosion-proof certification technical requirements for such equipment, Zhongnuo Testing has summarized years of industry experience, mainly including the following points:
(1) The explosion-proof performance only considers the electrical part, including the installation, connection, and grounding between electrical components, without considering the steel structure part.
(2) Electrical components require the purchase and installation of explosion-proof certificates or explosion-proof 3C certificates. If suitable explosion-proof electrical components cannot be purchased, explosion-proof/positive pressure installation methods can be considered.
(3) The explosion-proof mark of the selected explosion-proof electrical components cannot be lower than the explosion-proof mark level of the entire machine
(4) The installation, electrical connection, and grounding of explosion-proof electrical components must comply with standard requirements
In terms of combination equipment certification, Zhongnuo Testing has a professional technical team and industry experience, which can provide explosion-proof design guidance such as positive pressure and explosion-proof, guide customers in the selection, installation, drawing and data preparation of electrical equipment, and also appoint engineers to conduct on-site testing, reducing customer certification costs and time costs. Successful evidence collection cases include robots, AGV carts, industrial ovens, high and low temperature boxes, hydrogenation machines, refueling machines, skid mounted refueling devices, chemical storage cabinets, dust removal equipment, etc. If you have any needs in this area, please feel free to send us a private message for further communication.
