Explosion-proof fan, centrifugal fan, axial flow fan, marine fan, anti-corrosion explosion-proof fan, mine fan, is one of our company's key sales products, specializing in manufacturing explosion-proof fan, beautiful appearance, short delivery period, high safety performance, explosion-proof Fan can do high pressure (high pressure, small air volume, suitable for long-range suction and ventilation), medium pressure (large air volume, low pressure, suitable for general suction and ventilation), high temperature resistance (applicable to high temperature environment), Anti-corrosion (applicable to the chemical industry, no fan is corrosive) Characteristics of the explosion-proof fan 1, with blowing and suction dual function, a machine dual-use, you can use suction, you can also use hair;
2, less oil or no oil operation, the output of the air is clean;
3. Relative to centrifugal fans and medium-pressure fans, the pressure is much higher, which is more than ten times that of centrifugal fans.
4. If the pump body is integrally die-casted and shock-proof mounting feet are used, then the requirements for the installation base are also very low, and even the fixed feet can be used to operate normally, which is very convenient and saves installation costs. And installation cycle
5, compared to similar fans, the operation of the noise is low, as RHG launched ultra-quiet vortex fan:
6, maintenance-free use; its loss parts are only two bearings, within the warranty period, basically do not require maintenance;
7, EX explosion-proof fan mechanical wear is very small, because in addition to the bearing, there is no other mechanical contact part, so the service life is of course very long, as long as it is under normal conditions of use, 3 to 5 years is completely questionable;
8, easy to install, easy to use!
9, the overall use of aluminum alloy material, the motor is explosion-proof motor, will not appear the phenomenon of friction sparks, use more confidence, better explosion-proof performance.
Explosion-proof blower parameter table:
EX-B explosion-proof high-pressure fan / EX-Y explosion-proof fan.
Safety Precautions: Allow air inlet temperature to be 40°C at room temperature. All above models can be used for heat insulation and corrosion treatment. Since high-pressure series fans may generate temperatures of up to 100°C during operation, they should be avoided in locations where dangers arise due to temperature rise during selection and use.
The fan configuration is as follows: All aluminum body blades are equipped with professional explosion-proof motors. The motor protection class is IP55, the insulation class is F grade, and the explosion-proof grade is the highest DIIBT4.
High-pressure insulation fan can be used in industrial applications to ensure the normal operation of the motor in a high temperature environment, fan, high temperature bearings, H pole motor to ensure that the motor runs, the motor shaft lengthened, shaft plus cooling fan to ensure that temperature is transmitted to the motor. Therefore, the fan can withstand the normal operation of 260 degrees temperature, quality assurance, welcome customers to inquire for the latest information on the fan.
Use points:
When the explosion-proof fan is running, the current consumed by the motor increases with pressure and vacuum. If the current is too large, it will cause the contactor load to trip. To prevent tripping, the working principle of the explosion-proof blower can be vacuum or pressure relief valve on the suction or exhaust side:
When the impeller rotates, due to the effect of centrifugal force, the wind vane causes the gas to move forward and outward, thus forming a series of spiral motions. The air between the impeller blades rotates helically and rotates. The gas outside the pump body is pushed into the side slot (inhaled by the suction port). When it enters the side channel, the gas is compressed and then returned to the impeller blade again. Accelerate rotation. As the air passes through the impeller and the side slots along a spiral track, each impeller blade increases the degree of compression and acceleration. As the rotation progresses, the kinetic energy of the gas increases, causing the pressure of the gas passing through the side channels to increase further. When the air reaches the connection point between the side slot and the discharge flange (the side channel narrows at the outlet), the gas is extruded out of the vane and exits the pump through the outlet muffler.
