摘要
介绍一种新研制的通风机──KJZ55型矿用压入式局部通风机，该机带有可调前导叶和前后消声筒，额定功率55kW。它采用一级动轮、子午加速轴流式结构，具有结构简单、排风量大、通风压力高和高效率低噪声等特点。适用于掘进长度1500m、瓦斯涌出量5m^3／min以下的综掘工作面通风。
This paper introduces a newly- developed mine local fan-Model KJZ55 mineforced draught fan which are provided withthe head adjustable front guide blade andback/front cylindrical mumers, having a ratedpower of 55 kW. This fan adopts the single stage rotary impeller and meridian acceleratedaxial construction, featuring a simple structure, large air-exhausting quantity, high ventilation pressure together with a high efficiency and low noise, which is suitable to ventilating the roadway drivage with a developmentlength of 1 500 m and a methane emissionquantity below 5 m3/min.
