喷射泵特点及其在加氢裂化装置的应用

注水泵是加氢裂化装置的关键设备,其作用是将软化水升压后送往高压空冷,溶解空冷管束中的氨盐。中海油惠州炼油360万吨/年中压加氢裂化装置注水泵选用喷射泵,此泵与传统的离心泵和往复泵相比,在结构上有较大区别。文章首先介绍了喷射泵的结构、原理、特点,其次论述了在加氢裂化装置的应用情况。

Characteristics of Roto-jet Pump and Application in Hydrocraking Unit

The water injection pump was the key equipment in hydrocraking unit,and its function was that softened water pressure-rise,transformed it to the high-pressured air cooled heat and dissolved ammonia salt in the tube bundle.3.6 MT/A Mid-Pressure Hydrocracking unit for CNOOC Huizhou Refinery selected the Roto-jet pump as the water injection pump,compared with the traditional centrifugal pump and the reciprocating pump,which was obviously different on structure.The components and operating principles of the roto-jet pump were introduced,and its application in hydrocraking unit was described.
