Centrifugal fan development space.wholesale mini fans.mini fan heater manufacturer

　　We all know that centrifugal fans play a very important role in many aspects of our production and life. Because of this, the centrifugal fan industry has been booming. But maybe some people will also be concerned about the future development direction of the centrifugal fan industry. Let's follow the Taiwan fan brand to understand the current industry space of centrifugal fans.

　　The main products of domestic centrifugal fan manufacturers include large industrial blowers, ventilators, gas blowers, coke oven blowers, multi-stage high-pressure centrifugal blowers, single-stage high-speed centrifugal blowers, etc., more than 50 series, and more than 400 specifications of energy-saving centrifugal fan products. Widely used in iron and steel smelting, thermal power generation, new dry process cement, petrochemical industry, sewage treatment, waste heat recovery, gas recovery and nuclear power and other fields.

　　Traditional businesses benefit from energy-saving renovations, and production capacity will replace market capacity of 2.16 billion yuan in the next three years. At present, more than 95% of domestic large-scale industrial centrifugal fan business revenue comes from the four major industries of steel, cement, thermal power, and petrochemical. Although steel, cement and other industries have experienced overcapacity problems , the construction of new production capacity will slow down, but with the large-scale industrial structure upgrading in my country, the continuous implementation of energy-saving transformation projects such as replacing large and small, energy saving and industrial environmental protection will generate a large number of centrifugal fans. According to the State Council's "Notice on Further Strengthening the Elimination of Outdated Production Capacity", it is required to close 100 million tons of outdated production capacity such as steel, cement and thermal power within 2-3 years. According to preliminary estimates, large-scale capacity replacement in downstream industries will increase the market capacity of large centrifugal fans by 2.16 billion yuan. The core competitive advantage lies in the "three excellent model" of leading R&D strength + excellent energy saving + advanced service.

　　Common types

　　The commonly used types of centrifugal fans are as follows:

　　1. Industrial centrifugal fan

　　2. Dust removal/environmental protection fan

　　3. Anti-corrosion/explosion-proof fan

　　4. High temperature boiler induced draft fan

　　The centrifugal fan is essentially a variable flow and constant pressure device. When the rotational speed is constant, the pressure-flow theoretical curve of the centrifugal fan should be a straight line. Due to the internal loss, the actual characteristic curve is curved. The pressure developed in a centrifugal fan is greatly affected by changes in inlet air temperature or density. For a given intake air volume, the highest intake air temperature (lowest air density) produces the lowest pressure. For a given pressure and flow characteristic curve, there is a power and flow characteristic curve. When the blower runs at a constant speed When , for a given flow, the required power increases as the intake air temperature decreases.
