Three product advantages< br/>The explosion-proof type of this product is a composite structure. Compact appearance, beautiful and practical.
The product is a cast aluminum alloy shell, using advanced one-time die-casting molding process. The die-cast product has a smooth surface, beautiful appearance, high density of metal structure, no bubbles and blisters inside the metal, good impact resistance, and explosion-proof performance of the product shell. Yes, there is a permanent explosion-proof mark directly pressed on the product.
After the surface of the product is processed by high-speed shot blasting, the surface is sprayed using advanced high-voltage electrostatic spraying technology. The plastic layer has strong adhesion and its anti-corrosion and anti-oxidation sunlight performance is significantly improved.
It is equipped with a variety of components such as universal switches, knobs, switches, buttons, instrument indicators, etc., which can be configured according to user requirements.
Multiple switch functions can be selected according to user requirements, with reliable performance. The switch is connected to the external handle through a rotating shaft, and the shaft sleeve is permanently fixed on the housing cover, which is strong and reliable and is a unique processing technology of our company. .
The ammeter adopts a special overload ammeter with high overload multiple and the range can be freely selected by the user. The indicator light adopts the special indicator light introduced by our company. It has excellent properties such as high brightness, long life and low power consumption.
All exposed fasteners are stainless steel.
The operating column is equipped with terminal blocks and is insulated with sleeves. The terminal blocks are fastened with special anti-loosening pads to ensure the stability of electrical performance.
The installation method of the operating column is generally column type, but it can also be made into hanging type or bridge type, or it can be specially made according to user requirements. Hanging type and bridge type installation can be made into upper or lower cables.
Either steel pipe or cable wiring is acceptable.
Meaning of the four application scope groups
Division of hazardous areas for explosive gas environments
Different countries and regions divide explosive hazardous areas according to their own standards. Our country divides explosive gas environments into zones and zones based on the frequency and duration of the occurrence of explosive gas mixtures. In accordance with the International Electrotechnical Commission
Area where explosive gas mixtures appear continuously or for a long time.
Area where explosive gas mixture may occur during normal operation.
The area is an environment in which explosive gas mixtures are unlikely to occur during normal operation or where explosive gas mixtures will only exist for a short period of time even if they occur.
Zones generally only exist in internal gas spaces such as sealed containers and storage tanks. Zones rarely exist in the actual design process and most cases belong to zones.
Explosion-proof electrical equipment is divided into two categories
Category I electrical equipment for underground coal mines
Category II electrical equipment used in places other than mines
Category II electrical equipment, according to its applicable The maximum test safety gap or minimum ignition current ratio of explosive gas mixtures is divided into three categories: II, IIB and II and is divided into six groups according to their maximum surface temperature.
Explosive gas mixtures are grouped according to ignition temperature, see table.
Explosive gas mixtures are classified according to their maximum test safety gap or minimum ignition current ratio R, see table.

Properties: Under the specified test conditions, the ratio of the minimum ignition current of the gas vapor explosive mixture to the minimum ignition current of the methane explosive mixture . China stipulates that gas and vapor hazardous substances are classified into Class II [forbidden words], Class IIB and Class II based on the minimum ignition current ratio. The minimum ignition current ratio is level II [forbidden word], and the level IIB is level II. For example, ethane, vinyl, and acetylene are classified as Class II [banned words], Class IIB, and Class II hazardous substances respectively.
