单螺杆泵在油田地面工程技术中已经发展为不可缺少的部分,因具有结构简单、投资少,效率高,节约能源的特点,使其在油气输送过程中被广泛应用。然而,螺杆泵的选择也极其重要,在油气输送过程所需泵的排量、进口流量、排量和扬程等因素,都直接关系到螺杆泵的工作效率。
The single screw pump has become an indispensable part in the field engineering of oilfields. Due to its simple structure, low investment, high efficiency and energy saving, the single screw pump has been widely applied in the oil and gas transportation. However, the choice of screw pump is also very important. The pump displacement, inlet flow, displacement and head lift needed in the process of oil and gas transportation are all directly related to the working efficiency of the screw pump.
