Is the flow rate of the air suspension blower adjustable?

In order to ensure that the air suspension fan can work normally, in addition to the reasonable structure, the installation must also meet the requirements. Therefore, we should properly select the parameters of the air suspension fan and adopt reasonable adjustment methods and starting measures to ensure the normal operation of the air suspension fan.

Then regulating the flow of the air suspension fan is a more important way. Flow regulation mainly consists of three methods: moving vane regulation, front guide vane regulation and speed regulation.

When the air volume is reduced, the border of the unstable area gradually moves in the direction of the small air volume. If the fan parameters are selected properly, the fan can be prevented from operating in the small stable area. When the two fans are running in parallel, the phenomenon of "robbing the wind" is prevented. Because the power consumed by the air-suspended centrifugal fan is constant at the Angle of the rotor blade device, the power consumption of the large air volume is smaller than that of the small air volume.

Therefore, in order to shorten the starting time and maintain the motor, the rotor blade Angle, speed and front guide blade Angle should be adjusted to a small, and the isolation baffle of the fan outlet can be started after the full opening. For fans regulated by the throttling air suspension blower plate, the throttling baffle should also be opened to the appropriate position to start, so as to prevent the operation in the unstable operating zone after starting.

The diameter of the pipe at the outlet of the air suspension fan should be as large as possible, not smaller, and the insect-proof net on the outlet device should be used to avoid flying insects. When encountering snow and ice, it should be started frequently to avoid the blockage of the fan outlet by heavy snow and ice. This is very important for air suspension blowers.

Since most of the air suspension fans are used in the open air environment, it is very common for the fans to encounter the above phenomenon, which requires the user to stop regular inspection of the fans. If the user is used again after a long-term shutdown, then the commissioning of the fan should be stopped again, and the device of the fan should be re-checked before commissioning, the base of the device should be higher than the roof, the appearance should be smooth, and the phenomenon of reaching out to avoid water leakage should be buried in advance before the device.
