The Design of the Resistive And Flaky Silencer That Fit the Fan;

Study on ventilators faults warning based on wavelet package and neural network;

Research on the Mine Ventilator Fault Diagnosis Expert System;

The mine ventilator fault diagnosis based on wavelet packet and support vector machine;

The running state and fault features of main fans in colliery is analyzed, the modern technology methods of the fault diagnosis and forecast to fans are studied with modern science and technology, and the feasibility and adaptability of these modern technology methods are inquired into, and the direction of future development is presented.

The normal condition of air flow through axial flow fans outlet was studied based on the phenomenon of air flow away from solid boundary.

This paper introduces centrifugal fanner and axial-flow fanner two kinds fanners, expounds the structure, functional principles, and technical features of them, probes into the selection principles and adjustment methods of mineral fanner.

Using frequency conversion to control 260 rolling mill's fanner and transfertable improves the producing condition and reduces equipement accident.

Adjustment on axial flow ventilation fan of model CAF - 28;

Installation of ventilation fan and air-conditioning units;

The technology principle, construction and design calculation of resistance noise reduction for HD6 5 1 big power local ventilation fan developed recently are discussed in this paper.
