Do you know high-pressure centrifugal fans?

Jun 15, 2021

The main structural components of the high-pressure blower are impeller, casing, air inlet, bracket, motor, bearing, etc. The impeller is composed of multiple blades, which is similar to the impeller of a gas turbine. The air in the middle of the impeller blades is affected by the centrifugal force and moves to the edge of the impeller, leaving the air pump for use with high energy. The dual bandwidth voltage motor can be used for the needs of current frequency and voltage in different places.


In a separate space, such as the other end of a plant or pipeline, install any negative pressure fan or equipment that can pump out dust, dust removal and smoke exhaust, it is the air in an independent space that produces one in and one out airflow, which is called negative pressure, and the positive air supply is called positive pressure. The negative pressure can discharge the hot gas, peculiar smell and dust out of the factory. In order to produce air convection in an independent space, in addition to equipment, it is necessary to calculate the total volume and total area of the plant, calculate the wind speed per second in the factory, and the number of air changes per hour in the whole plant.


The casing will produce a high temperature during the operation of the high-pressure fan, which is mainly due to the ability to generate more heat when the air is compressed. The greater the pressure, the higher the temperature and the faster the speed. Therefore, the regular inspection of the fan is very important. If dust is found to accumulate, the staff need to clean up in time, which cannot affect the heat dissipation of the high-pressure fan.
