摘要：
Overheating of a process liquid retained in a reservoir of a multiphase pump during extended gas slugs is avoided by circulating a cooling liquid in thermal contact with a process liquid through an external cooling apparatus, which can include a heat exchanger. In some embodiments, process liquid from the reservoir is circulated through the cooling loop, while in other embodiments a separate cooling liquid is circulated between a reservoir heat exchanger and the external cooling apparatus. The liquid in the cooling loop can be circulated by a separate cooling pump, or process liquid can be circulated through the cooling loop due to a pressure differential between an inlet and an outlet of the cooling loop within the multiphase pump. The multiphase pump can be a twin screw pump, and the reservoir can be formed between outer and inner casings of the multiphase pump.
摘要（中）：
通过使冷却液体与处理液体热接触通过外部冷却装置循环来避免在延长的气体塞中保留在多相泵的储存器中的处理液体的过热，所述外部冷却装置可以包括热量 器。 在一些实施例中，来自储存器的处理液体循环通过冷却回路，而在其他实施例中，单独的冷却液体在储存器热交换器和外部冷却装置之间循环。 由于多相泵内冷却回路的入口和出口之间的压力差，冷却回路中的液体可以通过单独的冷却泵循环，或者工艺液体可以循环通过冷却回路。 多相泵可以是双螺杆泵，并且可以在多相泵的外壳和内壳之间形成储液器。
