FX-2 explosion-proof fan manufacturer direct sales of medium voltage explosion-proof blower for use in flammable and explosive places

Description :

　　Principle of explosion-proof fan:

　　The explosion-proof signs are CT4, dI, dIIAT4, and dIIBT4, which are respectively applicable to fixed equipment or factory IIA and IIB levels underground in coal mines, and places where combustible gases or vapors form explosive mixtures with air in temperature groups T1-T4; The protection level of the main body shell is IP44, which can also be made into IP% 4, and the protection level of the junction box is IP54; The rated frequency is 50Hz, and the rated voltage is 380/660, 660/1140V. Our fan impeller is directly installed on the motor rotor and is completely contactless compression. Due to the installation of motor bearings outside the compression chamber, even under the largest pressure difference, the maximum operational reliability of the machine can be ensured. Gas is sucked in through the suction port, and when it enters the side channel, the rotating impeller gives the gas a velocity in the direction of rotation. At the same time, the centrifugal force on the blades accelerates the gas outward and increases the pressure. As the rotation progresses, the kinetic energy of the gas increases, further increasing the gas pressure along the side channel. As the side channel narrows at the beginning of the outlet, gas is squeezed out of the blades and passes through the outlet to silence the cotton pump body.
