监控巷道风量分配的正确性,可以靠固定安装的速度转换器,或者靠ACO-3型或MC-13型叶式或杯式风速计。在知道风流速度后,风量可以很容易地算出。全苏矿业劳动安全科学研究所研制了新型的监测风量的转换器(ДCB-2型与ДKB-1型)。ДCB-2型转换器预定用在高含尘与高温度条件下,其技术特性如下:测量范围(m/s) 0～2.5;0～5.0;0～10灵敏度(m/s) 0.2绝对误差(m/s) ±0.1类型磁力转速计ДKB-1型风量转换器的技术参数如
The correctness of the distribution of air flow in the roadway can be monitored by a fixed-mounted speed converter or by an ACO-3 or MC-13 leaf or cup anemometer. After knowing the speed of the wind, the air volume can be easily calculated. All Su Institute of Mining and Labor Safety developed a new type of converter (ДCB-2 and ДKB-1) for monitoring air volume. The technical specifications of the ДCB-2 converter are intended to be used under conditions of high dust and temperature. Measurement range (m / s) 0 to 2.5; 0 to 5.0; 0 to 10 Sensitivity (m / s) 0.2 Absolute error (m / s) ± 0.1 Type Magnetic tachometer ДKB-1-type air volume converter technical parameters such as
