进口采样泵，采样流量稳定，噪音小。
取样时通过控制采样流量，使样气流速模拟取样点管道中煤气流速达到等速取样的条件。
When sampling, the speed of sample gas is similar to the actural pipe gas by controlling the sample gas flow.
在使用普通型采样管时，为了满足采样现场的要求，应有一个与之相适应的等速采样流量近似计算公式。
When using a common sampling tube, a formula for approximate calculation of the flow in the sampling tube is needed to meet the request of equi-speed sampling.
