Impeller: It consists of 12 rearward, tapered, single circular arc blades of equal thickness. The blades are welded to the front and rear discs. The middle and rear discs are riveted. After the impeller is manufactured, static and dynamic balance correction and aerodynamic functions Good, high efficiency, stable work, safe and reliable. Air inlet: It is a whole welded part installed on the side of the fan. The cross-section parallel to the axial direction is tapered in the front and curved in the back, so that the gas can enter the impeller smoothly with little gas loss.
High-pressure centrifugal blower casing: the whole volute is welded by general steel plate.
Transmission part: It is composed of main shaft, bearing box, belt pulley, etc. The main shaft is made of high-quality carbon steel, and rolling bearings are installed in the bearing box of gray iron castings to support the impeller and make it work safely.
Bracket: It may be generally welded between angle steel and steel plate to reliably support the fan and connect it to the foundation.
The high-pressure centrifugal fan is based on the principle of converting kinetic energy into potential energy, using a high-speed rotating impeller to accelerate the gas, then decelerate, change the flow direction, and convert kinetic energy into potential energy (pressure). The fan can be made into two forms of right-turning and left-turning. When viewed from the motor side, the impeller rotates in a clockwise direction and is called a right-handed fan, which is represented by "right"; when it rotates in a counterclockwise direction, it is called a left-handed fan and is represented by "left".
The outlet position of the fan is expressed in terms of the outlet angle of the casing. "Left" and "Right" can be made into six angles of 0, 45, 90, 135, 180, and 225.
The ventilation and dust removal system is composed of fans, pipes and dust removal equipment. The air volume and pressure of a centrifugal fan not only depend on the performance and speed of the fan itself, but also on the ventilation resistance of the system. Turbine fan When the speed of the centrifugal fan is constant, the greater the resistance of the system, the actual ventilation of the fan will decrease; on the contrary, the decrease of the system resistance will increase the actual ventilation.
