1. Explosion-proof Principle:
- The flameproof type is able to withstand the explosion pressure generated when the internal explosive mixture explodes through a solid shell and prevent the internal explosion from spreading to the explosive mixture around the shell.
- The increased safety type is to take measures to improve the safety level on the equipment structure that does not generate electric arcs, sparks, or high temperatures that may ignite the explosive mixture under normal operating conditions to avoid these dangerous phenomena under normal and approved overload conditions.

1.Requirements for Explosion-proof Grade:
First, determine the hazard zone level of your workplace (such as Zone 0, Zone 1, Zone 2) and the type of explosive mixture (such as gas, dust, etc.),

1.Shell Design:
Its shell has sufficient strength and sealing performance, which can withstand the internal explosion without damage and prevent the internal flame and explosion products from spreading to the outside.

The explosion-proof function of the explosion-proof motor is mainly achieved in the following ways:

In the field of explosion-proof motors, we have become the leader in the industry by virtue of excellent technology, strict quality control and high-quality services. The following are our significant advantages:

An explosion-proof electric motor is a type of motor specifically designed and engineered to operate safely in environments where there is a risk of explosion due to the presence of flammable gases, vapors, dust, or other combustible substances.

It has the following characteristics and advantages:
1.Explosion-proof Performance:
Adopting a special explosion-proof design and structure, it can prevent sparks, arcs, etc. generated inside from igniting the dangerous gases or dust outside, and also prevent external explosions from affecting the safety of internal equipment and personnel.

1.Reasonable Structural Design:
The structure of the cabin should adopt explosion-proof structural designs such as flameproof type and increased safety type. For example, a metal frame with sufficient strength and stiffness should be adopted to ensure that the outer shell can withstand an internal explosion without damage; the structures of doors, windows, vents and other parts should be designed reasonably to prevent the spread of explosion.

The working principle of the explosion-proof air conditioner is similar to that of ordinary air conditioners. It regulates the air through components such as compressors, condensers, evaporators and throttling devices. However, in order to meet the explosion-proof requirements, the explosion-proof air conditioner has undergone special design and treatment in terms of structure, electrical system, components, etc.

The cabinet-type explosion-proof air conditioner looks similar to the common cabinet air conditioner and usually has a greater cooling and heating capacity, which is suitable for larger spaces.

1.Installation Qualification:
The installation work must be carried out by personnel with professional qualification for the installation of explosion-proof electrical appliances to ensure that the installation process complies with explosion-proof standards and safety requirements.

1.Ventilation Conditions:
Check the air circulation around the installation location. You can observe whether there are obstacles that hinder the flow of air in the surrounding area, such as walls and large equipment being too close, which affects the normal exchange of air. You can also feel the degree of natural air circulation at this location to ensure good ventilation conditions, which is conducive to the heat dissipation and normal operation of the air conditioner.
