油隔离泥浆泵属特殊型双缸双作用往复泵。它与一般往复泵的基本区别在于活塞缸与阀箱之间装置了一套主要由油隔离罐和乙形管组成的油隔离系统(附图)。在油罐中,被输送的矿浆和油因比重差而自然分离,上部的油与活塞缸连通,下部的矿浆通过乙形管与阀箱连通。 Oil isolation mud pump is a special double cylinder reciprocating pump. Its basic difference with the general reciprocating pump is that the piston cylinder and the valve box are equipped with an oil isolation system consisting mainly of an oil isolation tank and a B-tube (with photos). In the tank, the pulp and oil being transported are naturally separated due to the difference in specific gravity, the upper oil is communicated with the piston cylinder, and the lower pulp is communicated with the valve box through the B-tube.
