Explosion proof high-pressure fan, 5.5KW annular explosion-proof blower characteristic ：
1、 Easy installation
The vortex explosion-proof blower can be installed at any time in the use place for compressed air or for evacuation. It can be installed in any horizontal or vertical direction.
2、 Strong structure
The body of the vortex explosion-proof i blower is cast with ADC12 aluminum alloy, which is different from the blower made of ordinary iron shell or AC10 aluminum alloy. ADC12 is made of the same material as the wheel drum of Mercedes Benz, which is more durable.
3、 High reliability
Apart from the impeller, the full air high-pressure fan has no other moving parts, and the impeller is directly connected to the motor, without gears or transmission belts, so it is highly reliable and almost maintenance free. There is no oil and gas, no pollution. When the impeller rotates, it will not contact with any unseen parts, and will not be lubricated. Therefore, it can ensure that there is no oil and gas.
4、 Low vibration
The parts of the fan are processed and tested by German and Japanese equipment. The parts of the running part are all designed with extremely precise balance, and the vibration rate is very low due to testing and calibration.
5、 Low noise
The explosion-proof fan is directly driven by a high-pressure low-noise motor, and the inlet and outlet are equipped with built-in silencing cotton, which can reduce the noise during operation.
6、 Humanized customization
The explosion-proof blower motor can be optionally installed according to customer requirements, such as Nanyang explosion-proof motor Jiamusi explosion-proof motor Xishan Anda explosion-proof motor high speed explosion-proof motor and other brands. The explosion-proof motor can be equipped with EX-DIIBT4 EX-DIICT4, IP55 IP56 IP65, etc.
Performance characteristics of explosion-proof high-pressure fan:
1. Low energy consumption: therefore, any method such as blowing and suction has its own efficiency, and has a conservative design in the range of high pressure. When the use situation changes, the explosion-proof vortex fan still operates safely.
2. Easy installation: it can be installed at the place of use at any time for compressed air or vacuum pumping. It can be installed horizontally or vertically.
3. High reliability: except for the impeller, there are no other moving parts, and the impeller is directly connected to the motor and driven by no gear or transmission belt, so the reliability is high and almost maintenance free.
4. Low vibration: the mechanical precision is high, and the other parts of the rotating part are all designed with extremely precise balance, so the vibration rate is very low due to testing and calibration.
Applicable to places with explosive gas mixture:
Ex -- DIICT4 series explosion-proof fan is applicable to methane or other gas transmission; EX -- DIIBT4 series explosion-proof fan is applicable to the environment of non mining working face under coal mine where dust or coal ash explosive mixture exists.
Ex-DIICT4 is applicable to the environment in which explosive gas and dust mixtures of Class II * and temperature groups T1, T2, T3 and T4 exist.
Ex-DIIBT4 is applicable to the environment where explosive gas mixture of T1, T2, T3 and T4 exists, which is Class II, Class B, and temperature group for factory use.
On the basis of FB-2 basic series electric fans, it can also be made into FB-2-W outdoor type, FB-2-WF1 outdoor medium anti-corrosion type and other climatic environments.
It uses flameproof enclosure to separate the electrical parts that may produce sparks, arcs and dangerous temperatures from the surrounding explosive gas mixture.
However, the enclosure is not sealed, and the surrounding explosive gas mixture can enter into the motor through the joint surface gap of each part of the enclosure.
Explosion may occur when contacting with spark, arc, dangerous high temperature and other ignition sources in the enclosure. At this time, the flameproof enclosure of the motor will not be damaged or deformed, and the explosive flame or hot gas can not ignite the surrounding explosive gas mixture when it passes through the gap of the joint surface.
The performance of the ammonia extraction explosion-proof suction fan meets the requirements of GB3836.1-83 General Requirements for Explosion proof Electrical Equipment for Explosive Atmospheres and GB3836.2-83 Explosion proof Electrical Equipment for Explosive Atmospheres Flameproof Electrical Equipment "d"; the motor power range is 0.55-200kW, and the corresponding seat number range is 80-315nun in the center of the seat; the explosion-proof signs are dI, dIIAT4, dIIBT4, They are respectively applicable to underground fixed equipment in coal mines or places with IIA, IIB grade plants and T1-T4 temperature groups of combustible gases or explosive mixtures of steam and air; The protection grade of the main body shell is IP44, which can also be made into IP% 4, and the protection grade of the junction box is IP54; Rated frequency: rated voltage: 380, 1660, 1140, 380/660, 660/140V; The insulation level of the motor is F, but the temperature rise of the stator winding is assessed according to B, which has a large temperature rise margin.
Explosion proof high-pressure fan to configure:
*1. Casing material: The explosion-proof blower adopts * degree die-casting aluminum. The die-casting aluminum is the same aluminum material as the wheel hub of Mercedes Benz. Compared with ordinary aluminum alloy, die-casting aluminum is stronger and lighter than iron casing fan.
*2. Motor performance: explosion-proof blower adopts explosion-proof motor. The explosion-proof motor is a wide frequency, wide voltage motor, which is listed as follows: industrial three-phase 220/380/415/660V, etc. The motor frequency can be 45-75HZ frequency modulation, IP55/IP65 protection class F insulation class. Its advantage is that domestic motors cannot reach the technology, which is favored by customers at home and abroad.
*3. Fan oil seal: German MERKEL oil seal is used for explosion-proof high-pressure blower, and fluororubber is used for German MERKEL, which can withstand - 25 ℃ to 300 ℃. Compared with ordinary oil seals, the temperature of the lip is 20~50 ℃ higher than the temperature of the working medium when working, which makes the performance more stable, maintenance free and longer life.
*4. Fan bearing: Germany SKF and Japan NSK brand bearings are used as the core components of explosion-proof high-pressure blower. The bearing can withstand 350 ℃ and 4000 rpm. For domestic Luoyang shaft and human-oriented bearing, the performance is stable, the noise is low, the maintenance is free, the service life is longer, and the fan can run longer 。
