  • Introduction to composition and structure of centrifugal ventilation and induced draft fan

    1. Composition of centrifugal ventilation and induced draft fan: the centrifugal ventilation and induced draft fan adopts single suction D-type transmission structure, and the fan and motor are connected by coupling. The fan body is mainly composed of casing, air inlet, rotor group (impeller and main shaft), bearing box, coupling and other parts. (the F-type transmission has double support and two bearing boxes. The single suction type has one air inlet chamber, and the double suction type has two air inlet chambers. C. Type B transmission has driving wheel and driven wheel. In addition to the components of the centrifugal fan, according to the needs of users, it can also be equipped with various external accessories, such as: motor, regulating door, overall support, electric actuator, muffler, etc. 2. Centrifugal ventilation

  • Dust problems of high pressure centrifugal fan

    Recall when you just purchased high-pressure centrifugal fans, did you ever encounter such a scene: ● did you ever purchase high-pressure centrifugal fan equipment with poor quality, which was not only scolded by the boss, but also disqualified in the performance appraisal, and the bonus was deducted? Have you been misled by the false propaganda of customers, believing that they have all kinds of certification, but the result is that there are no products? Have you ever been in a cautious shop and thought you were careful

  • Practical operation of fan surging, stalling and rushing wind

    Stall and surge are two different concepts. Stall is a hydrodynamic phenomenon caused by the structural characteristics of the blade. Some basic characteristics of stall, such as the rotation speed of the flow separation zone, the starting point and the vanishing point of the flow separation, have their own laws, and are not affected by the capacity and shape of the pipeline system of pumps and fans. Surge is a manifestation of the oscillation characteristics after the performance of the pump and fan is coupled with the pipeline system. Its amplitude, frequency and other basic characteristics are affected by the pump

  • What are the advantages of high pressure centrifugal fan

    At present, the market demand for high-pressure centrifugal fan is very large, more and more industries in the production process will be more or less used. And when it is used, the effect is quite good, so people can rest assured when using it. Under normal circumstances, the advantages of high-pressure centrifugal fan will be reflected in the following aspects, the first is that the energy-saving effect is better. The consciousness of environmental protection is very strong in modern society, especially for the production type. And the device is in operation
