Dust explosion-proof fan overview
The fan uses a flameproof enclosure to isolate electrical components that can generate sparks, arcing and dangerous temperatures from the surrounding explosive gas mixture. However, the enclosure is not hermetically sealed, and explosive gas mixtures from the surroundings can enter the interior of the motor through the gaps between the joint surfaces of the various parts of the enclosure. Explosion may occur when it comes into contact with ignition sources such as sparks, arcs, and dangerous high temperatures in the enclosure. At this time, the flameproof enclosure of the fan will not be damaged or deformed, and the explosive flame or hot gas will not ignite the surrounding explosive gas mixture when it is transmitted through the gap between the joint surfaces. 1, explosion-proof performance in line with the new national electrical safety standards: explosion-proof performance in line with GB3836.1 - 2010 "electrical equipment for explosive gas atmospheres Part 1 General requirements" and GB3836.2 - 2010 "electrical equipment for explosive gas atmospheres Part 2 Explosion type d" provisions, also in line with IEC 60079 - 1 and European standards. 2, high explosion-proof, reliable operation: motor protection pole IP55, shaft penetration position using V-type shaft seal ring, junction box using circular stop plus seal ring, improve the processing accuracy of main parts, base using parallel vertical fin structure, increase the heat dissipation area and other electrical and mechanical design measures, in terms of dust and water to improve an equal pole, motor operation more reliable.
Dust explosion-proof fanis under normal operating conditions will not produce arcs, sparks or dangerous high temperature motor structure, and then take some mechanical, electrical and thermal protection measures to further avoid normal or approved overload conditions arc, spark or high temperature hazards, thereby ensuring its explosion-proof safety.

If special voltage is required, it can be customized according to requirements.
Working principle of dust collection explosion-proof high-pressure fan
After the power supply is turned on, the fan rotates. Because the impeller has a groove design, it will drive the air flow, so the air enters the pump body through the air inlet, and the air is stirred inside. Each groove is pressurized by vortex type, and a cycle of pressurization is formed to form powerful airflow energy. It is discharged from the pump body through the air outlet for use.
Dust collection explosion-proof high-pressure fan structure
1 . Impeller: involute profile is selected, and the volume utilization rate is high. 2. Bearing: Type 3000 double row radial spherical roller bearing is used as the positioning end near the coupling end. 32000 type single row radial short cylindrical roller bearing is selected as free end near gear end to adapt to axial displacement of rotor during thermal expansion. 3, the body: by the shell and left and right wallboard composition. The left and right wall plates and bearing seats and sealing parts installed in the left and right wall plates can be mutually used. 4, base: medium and small fans are equipped with a common base, large fans only equipped with fan base, easy to install and debug. 5. Transmission mode: mainly coupling direct connection. If the performance specifications require, you can also choose the V-belt pulley speed change mode. Coupling selection of flexible coupling, can ease the impact and compensate for a small amount of axis deviation. In addition to electric motors as drive motors, steam turbines or other drive motors can also be used for large flow fans. nbsp;

, ultra-quiet type, no noise: the motor runs directly, and by adding an integrated sound suppression facility, the phenomenon of high pressure fan noise is improved, so as to achieve the effect of silence. 2, high reliability When the use of changes, the machine can still operate safely. In addition to the impeller, the high-pressure blower has no other action, so the reliability is almost maintenance-free. Using precision outer bearings with good heat dissipation, it has the following advantages: high compression ratio; low bearing operating temperature; long grease life; maintenance-free. 3, easy to install fully equipped, can be installed and used at any time, for compressed air or for vacuum, can also be installed in the horizontal or vertical direction. 4, oil-free pollution-free impeller rotation, not in contact with any part, free of lubrication, so can ensure pollution-free. 5, after many years of manufacturing experience, precision mechanical design plus careful motor with standard instrument testing, the use of all parts can meet the requirements, the use of standard ip54, F class motor efficiency, very few failures, between the motor and blower shaft seal test, to prevent foreign matter from entering. At the same time, in order to ensure the functional effect, each blower is strictly tested before leaving the factory. 6, voltage: international voltage type, 50HZ 60HZ are available, whether your product is exported to Europe and the United States using 60Hz, high voltage countries, or the Middle East, Africa and other countries and regions using 50Hz voltage, fans can meet the requirements, functional production complete, so that you have no worries!
