Guidelines for the selection of explosion-proof products shared by China Explosion Proof Lamp Supplier.

When selecting explosion-proof products, attention should be paid to the main elements such as blasting gas environment, protection grade, anti-corrosion grade requirements, so as to ensure that the explosion-proof products fit the application requirements. In case of upgrading or modification, it is necessary to replace the explosion-proof products of corresponding grades and groups in time to ensure environmental safety. Detailed selection criteria are as follows:

1. safety and reliability criteria: the category, grade and group of equipment shall be appropriate to the operating environment;

2. economic criteria: equipment type selection is not required to be high; for products of the same grade, factors such as price, life, reliability, operating cost and energy consumption, and availability of spare parts should be considered;

3. environmental adaptability criteria: considering environmental temperature, humidity and atmospheric pressure; Shell protection level and corrosion resistance, etc.;
