What are the matters needing attention when using a high-pressure centrifugal fan?

2020-05-13

First confirm the function of the high-pressure centrifugal fan, and find the pressure-flow curve corresponding to the high-pressure centrifugal fan; if you read the wrong curve, sometimes the selected product cannot be used; according to the calculated pressure and flow, find the same time on the graph Satisfy the operating curve above the operating point corresponding to the pressure and flow; then select the type of high-pressure centrifugal fan based on the operating curve. High-pressure centrifugal blowers need to pay attention to the technical parameters of high-pressure centrifugal blowers: power, air volume and pressure.


What are the matters needing attention when using a high-pressure centrifugal fan?

High-pressure centrifugal fans are currently widely used for conveying materials, because they are characterized by small flow, high air pressure, good ventilation and air supply, so they are widely used for conveying materials.


The fan must be tested before the official use of the fan; before the machine is used, first check whether there are any objects in the fan and pipes that hinder rolling; the conveyed gas must not contain more viscous substances, and the dust and hard particles contained in the medium cannot More than 150mg/m3. The high-pressure centrifugal fan should not be started or stopped too frequently, otherwise it will cause the motor to burn.

Regularly clean up the accumulated dust and oil on the surface of the wind wheel to avoid damage to the wind wheel's dynamic balance and increase the oscillation. The high-pressure centrifugal fan can not be used when the inlet and outlet are not connected to the pipe, otherwise the motor will burn out due to overload; do not let debris block the air inlet and outlet of the motor cooling fan and the heat dissipation teeth on the motor surface to avoid poor heat dissipation of the motor The resulting motor burns;


The above is the answer that the professionals of the high-pressure centrifugal fan manufacturer gave us. As long as the high-pressure centrifugal fan pays attention to these problems during operation, the working efficiency of the fan will be greatly improved, and the safety during operation will be ensured.
