Zhangqiu's latest multi-stage centrifugal blower, low-noise multi-stage centrifugal blower, centrifugal fan manufacturer single-stage and multi-stage centrifugal blower are both in the process of the rotation of the working wheel. Due to the action of the rotating centrifugal force and the expanded flow in the working wheel, the The velocity of the gas is increased and the velocity energy is subsequently converted into pressure energy in the diffuser. The difference is that a single-stage centrifugal blower has only one set of impellers, and the compression of air is completed in one step, while a multi-stage centrifugal blower has multiple sets of impellers on a main shaft, and the compression of air is completed gradually among multiple sets of impellers. Since the centrifugal fan relies on increasing the flow speed of the air, that is, the kinetic energy of the air, to compress the air and increase the pressure, so to obtain the same pressure, the impeller of a single centrifugal fan must be dozens of times higher than the speed of a multi-stage fan. Usually, multi-stage centrifugal fans The speed of the blower is only a few thousand revolutions, while the speed of the single-stage centrifugal fan is as high as tens of thousands or even hundreds of thousands of revolutions. Since the provision of pressure depends largely on the increase in rotational speed, and the provision of rotational speed is limited by balanced lubrication and material properties, single-stage centrifugal fans are more commonly used in low-pressure situations, and are more commonly used in high-pressure conditions. Multi-stage centrifugal blower.
Single-stage centrifugal fans generally rely on gearboxes to obtain extremely high speeds. Because the speed is extremely high, the control and maintenance of the fans are particularly important. They must be equipped with a separate lubricating oil station. At the same time, the high speed brings many components. For example, the blades wear more, so the service life of single-pole centrifugal fans is shorter than that of multi-pole centrifugal fans.
The main disadvantages of single-stage centrifugal fans (relatively) are the complexity of the mechanism. The unit has auxiliary mechanisms such as a lubricating oil station and a gearbox and is set at a high speed. It is noisy and requires a lot of maintenance. The maintenance is difficult because the parts of the fan wear out quickly. , and the requirements for balanced assembly are extremely high, the control is complex, and the operation is difficult. The fan is prone to vibration
