Methane gas conveying fan

Methane gas conveying fanLocation of use for explosion-proof through type medium pressure blower:

Zone 0: A place where explosive mixtures in an explosive environment appear continuously or exist for a long time in the form of gas, vapor, or mist.

Zone 1: A location where explosive mixtures in the form of gas vapor or mist may occur in an explosive environment during normal operation.

Zone 2: During normal operation, explosive mixtures in the form of gas vapor or mist are unlikely to occur in explosive environments, and if they do occur, they are only occasional and short-lived places. Usually, 'short duration' refers to a duration of no more than 2 hours.

Zone 3: Places where explosive dust or combustible fibers mixed with air may occur continuously, frequently for a short period of time, or exist for a long time under normal circumstances

Zone 4: Under normal circumstances, explosive dust or combustible fibers mixed with air may form explosive dust mixtures due to dust leakage and other reasons

Zone 5: A location where explosive dust mixtures are unlikely to occur during normal operation and only occur in the event of a malfunction.

Zone 6: During the normal operation of explosion-proof fans, if there are flammable particles, metal particles, or dust in the area, the operation or use of explosion-proof fans is prohibited.

Explosion proof motor description: Explosion proof motors are mainly used in coal mines, oil and gas, petrochemical and chemical industries. In addition, it is widely used in sectors such as textiles, metallurgy, urban gas, transportation, grain and oil processing, papermaking, and medicine. Explosion proof motors, as the main power equipment, are usually used to drive pumps, fans, compressors, and other transmission machinery. (In short, motors used in hazardous areas that do not pose a danger)

Scientifically classify and grade the explosive hazardous media in factories or mining areas according to their ignition energy, relatively low ignition temperature, and the time period of the existence of explosive hazardous gases on site, in order to determine the explosion-proof signs and forms of on-site explosion-proof equipment.

Explosion proof mark format:

Explosion proof grade description:

IA level:

Electrical equipment that cannot ignite explosive gas mixtures during normal operation, one fault, and two faults.

During normal operation, the safety factor is 2.0;

When there is a malfunction, the safety factor is 1.5;

When there are two faults, the safety factor is 1.0.

Note: Contact points with sparks must be equipped with explosion-proof enclosures, airtight enclosures, or double the safety factor.

Methane gas conveying fanCan be divided intoHigh voltage explosion-proof fan, medium voltage explosion-proof fan, variable frequency explosion-proof fan, insulation explosion-proof fan, centrifugal explosion-proof fan, high temperature resistant explosion-proof fan, explosion-proof high-pressure air pump; Explosion proof fans for conveying dust, explosion-proof fans for conveying gas, explosion-proof fans for mining, etc;

FX-3 medium voltage explosion-proof fanThe bearings adopt high-speed and high-temperature resistant bearings, the high-pressure fan cover adopts a sheet-like heat dissipation design, and the high-pressure fan adopts the principle of bearing front design. Two bearings are placed at the front end of the fan blades and the rear end of the motor to achieve dynamic balance configuration and facilitate heat dissipation. The front end of the fan blade has a heat sink for heat dissipation, while the bearing at the back end works under the built-in cooling fan of the fan, thus keeping the bearing working at low temperatures,
Explosion proof fan motors are designed and developed based on the actual situation of China's explosion-proof fan motor industry and market, providing a safer and more reliable new generation of power equipment for industries such as coal, petroleum, and chemical.
