Matters needing attention in installation of High pressure centrifugal Fan

Wuxi JN Fan Co.,Ltd | Updated: Dec 27, 2018

According to the principle of converting kinetic energy into potential energy, the high pressure centrifugal fan accelerates the gas by using the high speed rotating impeller, then slows down, changes the flow direction, and converts the kinetic energy into the potential energy. High pressure centrifugal fan is widely used in metallurgy, building materials, chemical industry and other industries. It is the most commonly used high pressure centrifugal fan. Low noise, flat performance curve, wide range of high efficiency and so on.


Before installing the high pressure centrifugal fan, it is necessary to check whether the impeller and the housing are deformed due to transportation and whether the connection is fastened or not, otherwise, the impeller and the housing should be installed and used only after repair. The installation of fan inlet and outlet should be of sufficient strength, rigidity, stability and durability.


The high pressure centrifugal fan must be fastened and installed with the anchor bolt hole of the fan or motor. It is strictly prohibited to use the inlet and outlet flange as the mounting force, and the weight of the air pipe should be supported by rigid support. When there is a bend or a sudden change in the section of the pipe in the range of the diameter of the wind turbine before and after the inlet and outlet, the resistance of the pipe will increase sharply, which should be avoided as far as possible.


The power supply of high-pressure centrifugal fan must ensure three-phase equalization and equal defect. The voltage can fluctuate within ±5% of the rated voltage. Electrical wiring must have professional responsibility to ensure the correct wiring. When installing high pressure centrifugal fan, the fatal damage caused by sundries entering the fan should be considered, and the corresponding protective parts should be set up. In the pipe network system, it is best to increase the air flow regulating valve in order to adjust the fan operating point.www.jnblower.com
