  • 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

  • What factors affect the price of centrifugal fan

    When we purchase any product, the first consideration is the price, and then we will consider the quality. Centrifugal fans are often used for exhaust, dust removal and cooling. However, many people will compare the product prices of many manufacturers when purchasing. Although this is very normal, what factors affect the product price? 1. Brand: different brands are one of the main reasons for the different prices of centrifugal fans. Moreover, sometimes there is a big gap between the imported products and the domestic brands. Therefore, which one should be chosen depends on the specific situation. If the use requirements are not high, domestic products can be selected

  • How to calculate the flow and pressure of high temperature fan

        How to calculate the flow rate and pressure of high-temperature fan selection? How to calculate the accurate answer? This is really a technical question. I believe this formula is difficult for many people. Some customers just know how much flow and air pressure their enterprises want to achieve, but they don't know how to calculate the air volume and model of high-temperature fan. If they are professional fan factory family members, they are asking customers to Calculate the result to select the model. We should pay attention to the calculation of high temperature fan, set the correct formula to calculate the model, as long as there is a bit of calculation error, then the following selection of model will be wrong, the following Zibo centrifugal fan

  • Reason analysis of high pressure fan's popularity

    As we all know, high pressure fan is widely used. But why is it so widespread? This has to give you a detailed analysis of the function and structure of the high pressure fan. First of all, the high-pressure fan has a dual-purpose function of suction and air supply. This is a function that other ventilators cannot achieve.   &nb
