进口高速离心风机哪家品牌好

进口高速离心风机Product Description:

It includes the motor and the primary volute and secondary volute respectively arranged on the pump cover of the first end face and the pump cover of the second end face of the motor. The primary impeller and the secondary impeller connected with the first end and the second end of the motor rotor are respectively arranged in the primary volute and the secondary volute. The primary impeller and the secondary impeller are installed back to back. The outlet of the primary volute is connected with the inlet of the secondary volute through the connecting pipe. The motor rotor is close to the first end The position of the second end is respectively provided with a first bearing structure and a second bearing structure. The rotor section between the second bearing structure and the second stage impeller is provided with a balance drum. The area between the first end face of the balance drum and the rear cover plate of the second stage impeller forms a high-pressure cavity. The area between the second end face of the balance drum and the pump cover of the second end face of the motor forms a low-pressure cavity. There is a gap between the outer circular surface of the balance drum and the inner wall of the shaft hole of the pump cover at the second end face, The second end face pump cover is provided with a vent hole.

进口高速离心风机characteristic:

Centrifugal high-speed fans, especially high-speed centrifugal fans with a speed of more than 8000r/min, generally adopt magnetic suspension or air bearing due to the limit speed and axial force borne by the shaft, which makes the manufacturing technology complex and the cost very high, and limits its popularization.

进口高速离心风机Principle:

The first bearing structure and the second bearing structure are respectively set at the position near the first end and the second end of the motor rotor. The first bearing structure and the second bearing structure of the motor rotor are high-speed thrust ceramic ball bearings. The fan structure is simpler and the production cost is reduced. Of course, the first bearing structure and the second bearing structure can also be other forms of high-speed ball bearings that meet the requirements of rated speed. In order to further balance the axial force of the first bearing structure and apply a preload to the bearing, the outer ring of the first bearing structure is provided with a waveform pressure spring pad
