Direct explosion-proof high-pressure vacuum cleaner fan

Direct explosion-proof high-pressure vacuum cleaner fan

Explosion proof high-pressure fanDue to the explosion-proof motor being equipped with a flameproof type, it generally meets the requirements of "Exd '" and has an explosion-proof level of BT4/CT4.

Explosion proof high-pressure blower is suitable for: chemical plants, coal mines, tunnels, boilers, canning, glass industry, ventilation and exhaust, automatic cleaning, packaging, fish pond oxygen supply, aeration, garbage decomposition, gas transportation, combustion oxygen reduction machine, cigarette filter forming machine, electroplating tank liquid mixing, atomization dryer, water treatment aeration, aquaculture, screen printing machine, photographic plate making machine, injection molding machine, automatic feeding and drying machine, liquid filling machine, powder filling machine, welding equipment, film machinery, paper transportation, dry cleaning clothes, cleaning purposes, air dust removal, dry bottles, gas transportation, chemical plants, coal mines, glass industry, fireworks and firecrackers, special places, pharmaceutical factories, etc.

Structural description of explosion-proof high-pressure blower

2.1 The explosion-proof structure of the electric fan has Ex dI, Ex dIIAT4, and Ex dIIBT4.

2.2 The protection level of the main body shell of the electric fan is IP55.

The cooling method of the electric fan is IC411.

2.4 The insulation level of the electric fan is F level, and the stator winding has a large temperature rise margin and a long service life.

The 2.5 electric fan has a cylindrical shaft extension, which is driven by a coupling or gear.

2.6 The stator winding of the electric fan adopts high-strength enameled round copper wire, which is vacuum pressurized and immersed in paint to form a complete whole. The winding and insulation have good electrical, mechanical, moisture-proof performance and thermal stability.

2.7 The rotor of the electric fan adopts a cast aluminum structure, and the rotor has undergone dynamic balance verification. The motor runs smoothly, with low vibration and noise.

2.8 The stator and rotor blades of the electric fan are made of high-quality electrical silicon steel sheets with high magnetic conductivity and low loss, resulting in low motor loss and high efficiency.

2.9 The bearings for the electric fan shall be low vibration and low-noise bearings specifically designed for electric motors. Double sided sealed bearings shall be used for machine seat sizes 160 and below, and waveform spring washers shall be installed at the shaft extension end to provide moderate pressure against the bearings and effectively prevent vibration and noise generated during motor operation. For machine seat sizes 180 and above, inner and outer cover structures shall be used, and retaining rings shall be used for axial fixation at the bearing locations to effectively prevent axial movement of the motor rotor.

To ensure reliable operation of the electric motor, the bearing structure of motors with a base size of 180 and above is equipped with an oil injection device. For motors with a base size of 250 and above, a position for bearing temperature monitoring sensing elements is reserved.

2.10 Motor fan and fan cover: Motors with a base size of 280 and below use anti-static plastic fans, which have low rotational inertia and low loss. Motors with a base size of 315 and above use cast aluminum or steel plate welded fans, which are lightweight and strong. The entire series of fans are connected to the shaft with critical connections, ensuring reliable operation. The wind cover is made of steel plate structure, which provides a ventilation area while preventing the intrusion of foreign objects of a certain size, ensuring smooth air flow.
