By understanding, the type of the outer rotor centrifugal fan is more, and the design of the type of equipment is reduced, and the impact of the airflow to the impeller is reduced, ensuring the normal operation of the airflow in the intake passage, thereby reducing the loss of traffic, improves The operating efficiency of the fan is promoted, and now, in order to ensure the treatment and application of the sewage factory, the safe operation of the outer rotor centrifugal fan puts forward new requirements, how to understand various types of problems when using the outer rotor centrifugal fan?
What problems can be solved by a rotor centrifuge fan?
At the first point, in the processing of the wastewater rotor centrifugal fan, prevention and vibration measures were taken, from the perspective of the design, compared several commonly used calculation methods, and the demand calculation formula design requirement, therefore feasible operation adjustment The Compact Fan Heater range is increased, and the outer rotor centrifugal fan can filter air while inhaling air, reducing the particulate matter in the air to reduce the problem caused by the use of high-pressure outer rotor centrifugal wind turbine, so the device has simple structure, strong survival ability The advantage that according to the test results, the efficiency does not decrease in the adjustment flow rate, resulting in a better use effect.
Second, now, the noise reduction problem in the use of the outer rotor centrifuge fan can be proposed. The method can reduce the noise from the outer rotor centrifugal fan. First, according to the basic theoretical theory of acoustic, determine the position of the noise and the outer rotor centrifuge. The main source of aerodynamic noise in the fan, and compares the analysis results with fan noise measurement results, which proves that the method can effectively determine the position of the pneumatic noise source.
After understanding the operation of the outer rotor centrifuge fan, the advantage of the device is reasonable, greatly improved the stability of the fan, reducing the noise issued by the runtime, measure the aerodynamic performance of the outer rotor centrifugal fan, according to wind noise The measurement method is required, which is used to calculate the aerial direction of the outer rotor centrifugal fan flow field, so the external rotor centrifugal fan unstable stream is calculated, and three parameters output from the volute are studied.
