What is a 9-19 9C centrifugal fan? When choosing to purchase a high-pressure centrifugal fan, it is also necessary to consider its purpose. In the 9-19 series centrifugal fans, this is mainly used for conveying materials. From the perspective of working principle, high-pressure centrifugal fans usually do not need to consider changes in gas specific volume due to their low gas flow rate and small pressure changes during use, and treat gas as an incompressible fluid. Yantai high-pressure centrifugal fans can be made into two types: right-handed and left-handed: when viewed from the side of the motor, the impeller rotates clockwise, which is called a right-handed rotating fan; The counterclockwise rotation of the impeller is called a left rotating fan.

From the perspective of centrifugal fan construction, the key components mainly include: the casing, which is generally made of steel plate, sturdy and reliable, and can be divided into integral and semi open types. The semi open type is easy to maintain; The impeller consists of blades, a curved front plate, and a flat rear plate; The rotor needs to undergo static and dynamic balancing to ensure smooth rotation and good performance; The transmission part is mainly composed of the main shaft, bearing box, rolling bearings, and pulley.

In fact, we can consider centrifugal fan equipment as a variable flow and constant pressure device. During its operation, when the speed is constant, the theoretical pressure flow curve of the equipment should be a straight line. Due to internal losses, the actual characteristic curve is curved.

After the work is completed, we need to shut down the centrifugal fan equipment according to the correct operation. The specific operation steps are: 1. First, open the vent valve in sequence and gradually close the exhaust valve; 2. Gradually close the intake throttle valve to 20-25 °; 3. Press the stop button and pay attention to any abnormal phenomena during the shutdown process.

After the centrifugal fan stops running for five to ten minutes, or when its bearing temperature drops below 45 degrees, the oil supply can be stopped. After the centrifugal fan unit stops, the rotor should be periodically rotated 180 degrees within 2-4 hours. What is a 9-19 9C centrifugal fan?
