Working Principle of High Pressure Centrifugal blower

In fact, the use of High Pressure Centrifugal blower is very extensive, and there are many factories producing high-pressure fans in our country, so when choosing high-pressure centrifugal fans, we must polish our eyes and make good choices. High-pressure centrifugal fan will inevitably cause energy consumption in the use process, and as far as high-pressure fan is concerned, its energy consumption is not low. What is the principle of high-pressure centrifugal fan that Xiaobian wants to tell you today?
No matter what kind of mechanical equipment, it depends on its working principle. Generally speaking, when the gas between the blades of the high-pressure centrifugal fan rotates in the impeller, it will be directly affected by the centrifugal force to obtain kinetic energy, and then directly discharged from the periphery of the impeller, through the guide of the volute, flow to the outlet of the fan, thus forming a negative pressure in the impeller. Control the impeller interior to produce external air. The flow rate continuously flows into the recharge device, which makes the high-pressure centrifugal fan discharge gas directly, which greatly promotes the progress of the work.
In the working process, the motor transfers power to the fan impeller through the shaft, and the impeller rotates to transfer energy to the air. Under the action of rotation, the air produces centrifugal force, and the blades of the impeller of the blower diffuse everywhere. At this time, the larger the fan impeller, the greater the energy received by the air, that is, the greater the pressure head of the fan. If the large impeller is cut off, it will not directly affect the air flow, but will only reduce the wind pressure.
High-pressure centrifugal fan is mainly composed of impeller and shell. The impeller of the small fan is directly installed on the motor, and the large fan is connected with the motor through a coupling or a belt pulley. Centrifugal fans are generally single-side air intake, with an impeller; large flow can be bilateral air intake, with two back-to-back impellers, also known as double-suction centrifugal fans. The front impeller produces the maximum pressure. When the flow rate and speed are fixed, the required impeller diameter is the smallest, but the efficiency is generally low. Then the rear impeller produces the smallest pressure, and the required impeller diameter is the largest, and the efficiency is generally higher. The radial impeller is between the two.
