当前测量井巷通风阻力的仪器很多,按测量方式来分有两类,一类是逐点测量的,这一类仪器有空盒气压计、恒温气压计:京大一式气压计等。但目前市售的只有空盒气压计一种;另一类是逐段测量的,属于这一类的仪器有微压计、倾斜式压力计。这两种仪器目前市场上均有出售。 空盒气压计购置和使用虽然方便,但分度值大,量度高,不宜用于巷道阻力测定。恒温气压计、京大一式气压计目前无售,现场自己制作也很困难,使用起来很不方便。
There are many instruments for measuring the ventilation resistance of the shaft at present. There are two types according to the measurement methods. One is the point-by-point measurement. The instruments in this category are available with a barometric pressure gauge and a constant temperature barometer. However, the current market is only a barometric pressure gauge; the other is measured by paragraph, belonging to this category of instruments have micro-pressure meter, tilt-type pressure gauge. Both devices are currently on the market for sale. Empty box barometer purchase and use although convenient, but the indexing value, high measure, not suitable for determination of roadway resistance. Constant temperature barometer, Beijing University one type of barometer currently no sale, the scene is also very difficult to make their own use is very inconvenient.
