Explosion proof high-pressure vortex fan, air pump, blower, fish pond explosion aerator, factory dust removal, factory direct sales
Explosion proof vortex fan is a high-pressure vortex air pump that can be used in flammable and explosive places. Its characteristic is that it does not generate any electric sparks during operation. It uses an explosion-proof shell to separate electrical parts that may generate sparks, arcs, and dangerous temperatures from the surrounding explosive gas mixture, effectively preventing the occurrence of dangerous situations. It is mainly used for pressurized transportation of gas and marsh gas, and for use in flammable and explosive places. Explosion proof grade is IIB
Explosion proof high-pressure fans are suitable for places where explosive gas mixtures exist:
The Ex -- DIICT4-- DIIBT4 series explosion-proof fan is suitable for non mining working face environments in coal mines where explosive mixtures of methane or coal dust are present.
Ex-DIICT4 is suitable for use in factories with Class II Phase A, temperature groups T1, T2, T3, and T4, in environments where explosive gas dust mixtures exist.
Ex-DIIBT4 is suitable for use in factory environments with Class II, Class B, temperature groups T1, T2, T3, and T4 explosive gas mixtures.
On the basis of the FB-2 basic series electric fan, it can also be made into FB-2-W outdoor type, FB-2-WF1 outdoor medium anti-corrosion type and other climate environments.
Explosion proof fans are used in places with high concentrations of flammable gases that require ventilation, such as underground coal mines and boiler rooms for the transmission of flammable gases. explosion-proofvortex blowerThe process requirement is that during the start-up and operation of the fan, sparks generated by the motor wiring terminals, stator and rotor, or other components should not come into contact with flammable and explosive gases from the outside, which may cause safety accidents. Rotating components will not generate sparks when they rub against the shell under special circumstances, in order to avoid causing serious consequences due to the formation of flammable gases. Of course, explosion-proof fans require explosion-proof motors to drive.
The explosion-proof level is Exd IIB T4, the motor insulation level is F, and the explosion-proof standard complies with the provisions of GB3836.1-2000 "Electrical Equipment for Explosive Gas Environments Part 1 General Requirements" and GB3836.2-2000 "Electrical Equipment for Explosive Gas Environments Part 2 Explosion proof Type D", as well as IEC60079-1 and European standards. Explosion proof blower is suitable for places or environments where flammable and explosive gases exist.
The label for explosion-proof vortex fans is generally EX d Ⅱ B T4 GB, with the following annotations:
Explosion proof mark Explosion proof grade Gas group Temperature group
D is the label for explosion-proof and explosion-proof products
Explosion proof level classification: Currently, both domestic and international explosion-proof levels are classified as Class II and do not have the ability to develop Class I
Working condition category Gas classification Representative gases Minimum ignition spark energy Under the mine Ⅰ methane 0.280mJ Factories outside the mine ⅡA propane 0.180mJ ⅡB ethylene 0.060mJ ⅡC hydrogen 0.019mJ Class I: Electrical equipment underground in coal mines; (Mining)
Class II: Electrical equipment for explosive gas environments other than coal mines and underground (factory use), generally equipped with this type of motor for fans
And Class II can be divided into Class IIA, Class IIB, and Class IIC. Equipment marked as Class IIB can be used under the conditions of Class IIA equipment; IIC is applicable to the usage conditions of IIA and IIB.
T4: Temperature group, the lower the surface temperature of the equipment, the better, so as not to easily cause motor burnout.
Temperature group Safe surface temperature of objects Common explosive gases T1 ≤ 450℃ 46 types of hydrogen, acrylonitrile, etc T2 ≤ 300℃ 47 types of acetylene, ethylene, etc T3 ≤ 200℃ 36 types of gasoline, etc T4 ≤ 135℃ Six types including acetaldehyde, tetrafluoroethylene, etc T5 ≤ 100℃ carbon disulfide T6 ≤ 85℃ Ethyl nitrate and Explosion proof high-pressure vortex fan, air pump, blower, fish pond explosion aerator, factory dust removal, factory direct sales
