基于振动信号测试煤矿主通风机转速的探讨

Discussion on Testing of Mine Main Fan Speed Based on Vibration Signal

国内现有检测检验机构对煤矿主要通风机转速的检测主要采用光电转速表测试,光电转速表测试传动轴外置的风机准确、方便,但是对于目前煤矿企业普遍采用的煤矿地面用防爆抽出式(对旋)轴流式通风机(FBCDZ系列风机)的转速时就显得无所适从。目前在我国汽车行业已经出现通过振动信号和虚拟仪器对发动机瞬时转速进行测量的研究理论,通过分析、比较发动机和风机的运转原理,将这个理论推广到煤矿主要通风机上。

Domestic existing inspection inspection institution of coal mine main ventilator speed detection mainly adopts photoelectric tachometer test, test the photoelectric tachometer shaft outer fan is accurate, convenient, but for the present widely used to mine coal mining enterprises to the ground with explosion-proof draw-out axial-flow fan to spin （FBCDZ series fan） speed is uncertain. At present in our country automobile industry has emerged through the vibration signal and the virtual instrument to measure the instantaneous engine speed research theory, through analysis and comparison of the engine and the fan, its are generalized to the theory of coal mine main ventilator.
