How to apply for explosion-proof certification for the whole machine?

In practical production, we often use complex explosion-proof electrical equipment or devices that are composed of several structures in combination to achieve a certain function, that is, combination explosion-proof electrical equipment or devices. For example, inspection robots, automated production equipment, lifting equipment, compressors, etc. When this type of equipment is applied to explosive locations, it is necessary to consider the explosion-proof performance of each explosion-proof electrical unit and the electrical and mechanical connections of the assembled components, as well as the protection of the shell, which is commonly referred to as whole machine explosion-proof certification.

To apply for the explosion-proof certification of the whole machine, it is first required that all electrical components in the machine use components with explosion-proof certification certificates, and the explosion-proof level requirement cannot be lower than the explosion-proof level of the whole machine; Secondly, for some non-standard functional electrical components, corresponding explosion-proof structural design needs to be considered; Another requirement is to evaluate the ignition sources such as friction, high temperature, and sparks of mechanical moving parts.

Here, Shenzhen Zhongnuo Testing Technology Co., Ltd. can only briefly introduce the requirements for explosion-proof certification of the whole machine. For details of the certification, please send us a private message for further communication. Zhongnuo Testing has accumulated rich experience in the field of whole machine explosion-proof certification, and can provide customers with explosion-proof selection, structural design, electrical connection and other services. We have obtained inspection robots, pry mounted refueling devices AGV、 Explosion proof certificates for products such as air shower rooms, filling machines, crushers, chemical cabinets, industrial ovens, and test chambers are welcome to inquire at any time!
