洗煤厂煤泥水流量的确定,是个比较复杂和困难的问题。用一般的仪器测量,因煤泥水中带有大量的煤粒、细泥,往往将仪器堵塞,使其无法测量;用电子仪表,因造价昂贵,一时尚不宜推广使用。因此,目前洗煤厂测定煤泥水流量,一般是将管道中煤泥水引进槽子或地沟进行流量测定。然而,采用液面纸片流速法,误差大,数据不可靠。若用体积法,又因洗煤厂各主要管道流量都很大(一般在
Coal washing plant to determine the flow of slime water is a more complicated and difficult issue. With the general instrument measurement, due to the slime water with a large number of coal, fine mud, often clogging the instrument, making it impossible to measure; with electronic instruments, due to high cost, a fashion should not be used widely. Therefore, the current measurement of coal washing plant coal slurry flow, the general is the pipeline into the ditch or trench slime for flow measurement. However, the use of liquid paper flow velocity method, the error is large, the data is not reliable. If the volume method, but also because of the major coal-washing plant flow are large (generally
