矿井通风机轴承温度测量,过去用气体压力式温度计,经使用证明该温度计存在故障多、反应慢、导管不易维护等缺点,曾多次因超温发生断轴、研轴等事故。为此,试制成以热敏电阻传感为元件的测温保护装置。该装置由电源、测温、报警三部分组成。 Mine ventilator bearing temperature measurement, past the use of gas pressure thermometer, the use of that the thermometer there are more failures, slow response, difficult to maintain the catheter and other shortcomings, has repeatedly broken down due to overheating, such as shaft research accident. To this end, the trial made of thermistor sensing temperature protection device components. The device consists of power supply, temperature measurement, alarm three parts.
