(续2008年第4期)泵的流量是受到严密控制的,所以稀浆的注射压力不会超过14kPa。当在下游的堵头处出现未被冲淡的稀浆时,就把下游的通气孔堵住。在稀浆通过环形间隙泵送时,通气孔可显
(Continued in 2008 4) pump flow is closely controlled, so the slurry injection pressure will not exceed 14kPa. When there is no dilute slurry in the downstream plug, put downstream vents blocked. Venting can be significant when the slurry is pumped through the annular gap
