What are the characteristics of FBCDZ(FCDZ) series extraction type contra-rotating axial flow main fan?

FBCDZ(FCDZ) series extraction type contra-rotating axial flow main fan (hereafter called fan) takes curve slide  orthogonal 3 dimension twisted blade technique. The design of blades of this series of high efficiency low noise main fan is based on lumped parameter optimal control theory, distribution parameter optimal control theory, numerical simulation of forward and inverse problems of full 3-dimension turbulance flow, and other modern theories. It aims to minimize flow losses and aerodynamic noise. It is a design method of controlling through multi parameters, like blade bending sweep, and using computer to realize synthetic aerodynamic performance and optimize its structure design.

This series fan can be customized according to the working condition parameters provided by clients, with the ventilation network parameters of large and middle sized mine as the basis. This ensures it to work at high efficiency. It is a new kind high efficiency, energy saving, low noise fan. It can be used for ventilation in metal mine, chemical mine, tunnel projects, etc.
