In recent years, China's chemical industry has been continuously building and expanding projects, and the demand for explosion-proof motors has been increasing year by year. However, some old motor equipment no longer has explosion-proof functions due to years of load or poor maintenance; 
In addition, the newly implemented explosion-proof standard GB3836-2010 has added a series of requirements for explosion-proof forms such as explosion-proof and increased safety. 
To ensure the safe and reliable operation of explosion-proof motors and meet standard requirements, it is particularly important to optimize and retrofit motors used in flammable and explosive gas environments.
