As a type of blower, centrifugal blowers are currently used in many electrical appliances. When the centrifugal blower is working, the wheels rotate at high speed, driving the air to be used at high speed, forming wind pressure and replenishing fresh air.
Judging from the working principle of a centrifugal blower, the compression process of air is usually carried out through several working impellers (or stages) under the action of centrifugal force. The pressure-flow characteristic curve of a centrifugal blower is a straight line, but due to frictional resistance and other losses inside the fan, the actual pressure and flow characteristic curves decrease gently as the flow rate increases. The corresponding power-flow curve of a centrifugal blower increases as the flow rate increases. increase and rise. When the fan runs at constant speed, the fan's operating point will move along the pressure-flow characteristic curve. The operating point of a fan during operation depends not only on its own performance but also on the characteristics of the system. As network resistance increases, the pipeline performance curve becomes steeper.
From the appearance, the centrifugal blower is beautiful and elegant, has good stability and performance, and is simple and convenient to install and maintain in the future. During operation, the optimized design is adopted to minimize the axial force. It is equipped with a high-efficiency impeller and is corrected by dynamic and static balance to make the whole machine run smoothly. There is no friction when running, so the noise produced is very small. In addition, there are devices that can be used for soundproofing. Basically no noise will be heard from the outside world. The blower bearings are lubricated with grease, and the bearing life is more than three years. The fan does not produce oil or gas when running. Fans with special requirements use lithium molybdenum disulfide grease to lubricate the bearings. The impeller adopts a special curve to reduce internal leakage and improve volumetric efficiency. Good sealing performance can reduce gas leakage. In terms of driving mode, motors with different voltages can also be used according to the characteristics of the user's power grid. SMAIT series blowers are very good at drying, processing air, blowing or vacuuming, and are highly used i
n chemical manufacturing, vacuum and other fields. As a blower with many advantages, it can be used in special environments, is simple to use, and is very flexible in operation. The product quality is excellent, so you don’t have to worry about any malfunctions during daily use. You can choose to use it with confidence.
