Explosion-proof technology training content1

Working in a inflammable and explosive environment is a very dangerous thing, we need to acquire a solid explosion-proof technology to guarantee personal safety problems. Today engineering basic content is mainly to introduce explosion-proof technology training, help operator to learn professional explosion-proof technology knowledge.

one, the concept of explosion-proof products

1, the application place of

1) General product requirements

performance is stable, reliable, easy to operate,

appearance beautiful, clear sign

the function is all ready, new

design conforms to the national standard or enterprise standard

2) In addition to the general requirements for general electric products, internal explosion proof, or due to internal explosion not causing the explosion of the surrounding environment, is a kind of special requirements, also must after explosion proof evidence submitted to production and sales.

3) Explosion-proof products applications

environment such as the coal mine gas

, coking, oil refining, chemical industry, petrochemical industry gas

gas gathering, transportation

oil RIGS

terminal

arms and ammunition production, Arsenal

space, missile launch base

power plant, coal dust,

coking gas factory

grain processing, cotton fiber processing

maritime and ferry

in general is a general electrical products, on the basis of conventional requirements, explosion-proof processing to rear can be used in hazardous areas of specialty products.

2, explosive environment with explosion-proof electrical equipment terms

1, the general term

1) Explosive environment with explosion-proof electrical equipment

the design and manufacture under specific conditions and does not cause the surrounding explosive electric equipment. ( The prescribed conditions is national GB3836. . . ). Under prescribed conditions do not cause the surrounding explosive environment lighting electrical equipment.

2) Explosive environment

contains an explosive mixture of environment

3) Explosive gas environment

contains environment of explosive gas mixture

4) Explosive dust environment

contains the environment with explosive dust mixture

5) Explosion-proof type

to prevent light surrounding explosive mixture, and specific measures to the electric devices in the form of a

6) Electrical equipment

according to the electrical equipment using the environment and divided into categories, the category can be divided into level

7) Maximum surface temperature

electrical equipment within the allowable range of the most unfavorable conditions run time, exposure to explosive mixture could not cause any surface of any part of the electrical equipment surrounding the highest temperature explosion of explosive mixture.

8) Temperature classes

according to the electrical equipment of the highest surface temperature group.
