Structure information about explosion-proof high pressure fan

Explosion-proof high-pressure fan has a great expansion role in many industries. With the strengthening of the government's requirements for environmental protection, safety and energy saving, people's awareness of safety and environmental protection has been deepened in metallurgy, electric power, building materials, mining, lifting, environmental protection, chemical industry, light industry and other industries. New results using explosion-proof motor, auxiliary fan fan overheating at startup current is too large to cause the flammable, explosive gas explosion due to leakage phenomenon, explosion-proof fan using regenerative design of principle of monolithic centrifugal wind leaf size is small, the air volume, high wind pressure characteristics, free maintenance, no oil and gas, long service life, high efficiency, energy saving, environmental protection, etc.

Explosion-proof high pressure fan is suitable for: Chemical plant, coal mine, tunnel, boiler, canned, glass industry, ventilation and exhaust, automatic cleaning, packaging, fish pond for oxygen, aeration, garbage decomposition, gas transmission, Burning down YangJi, forming machine, electroplating bath stirring, spray dryer, aerated water treatment, aquaculture, silk screen printing, photographic plate maker, injection molding machine, automatic feeding dryers, liquid filling machine, powder filling machine, electric welding equipment, film, paper, shipping, dry cleaning, cleaning, air cleaning, dry bottles, gas transmission, chemical plant, coal, glass industry, Fireworks and crackers, special places, pharmaceutical factories, etc.

Explosion-proof high pressure fan structure description:

1,Protection grade of main body shell is IP55.

2, flameproof structure with Ex dI, Ex dIIAT4, Ex dIIBT4.

3, Cooling mode is IC411.

4, explosion-proof high pressure fan has a cylindrical shaft extension, by coupling or gear transmission.

5, insulation grade is F, the stator winding temperature rise margin, long life.

6, the rotor adopts cast aluminum structure, rotor dynamic balance check, the motor runs smoothly, small vibration, low noise.

7, stator and rotor punching sheet adopts high magnetic conductivity, low loss, high quality electrical silicon steel sheet, low loss and high efficiency.

8, the stator windings of the explosion-proof high voltage fan are made of high strength enamelled round copper wire, and become a complete whole by the vacuum pressure dipping process. The windings and insulation have good electrical, mechanical, moisture-proof performance and thermal stability.

9, selection of bearing special low vibration, low noise bearings, motor frame size 160 and below USES double sealed bearing, a waveform spring washer on the shaft extension end to moderate pressure on bearing, effectively restrain the vibration and noise when motor is running, frame # 180 and above using internal and external structure, and the bearing parts adopt baffle ring axial fixation, Effectively prevent the motor rotor axial channeling.

10, motor fan, air hood: the motor with frame no. 280 and below adopts anti-static plastic fan, which has small moment of inertia and low loss. The motor with frame no. 315 and above adopts cast aluminum or steel plate welding fan, which is light in weight and high in strength. The air hood is a steel plate structure, which can get a large ventilation area on the premise of preventing the invasion of foreign objects of a certain size, so that the air road is smooth.
