一概述随着化工行业的发展,特别是近年来石油替代品煤化工行业的发展,空分设备正朝着大型化,气体产品压力等级高、液体产品多、产品纯度高、运行成本低及设备操作稳定可靠等方向发展。在空分工艺流程中内压缩流程、无氢制氩流程普遍用深冷低温液体泵(以下简称低温液体泵)作工艺泵和生产泵,低温液体泵在空分工艺中起着重要的作用,低温液体泵的运行好坏直接关系到整套空分工艺是否能实现设计指标。
Overview With the development of the chemical industry, especially in recent years, the development of alternative petroleum chemical industry, air separation plant is moving towards large-scale, high pressure gas products, liquid products, high purity, low operating costs and equipment Stable and reliable operation of the direction of development. In the process of air separation within the compression process, hydrogen-free argon production process commonly used cryogenic liquid pump (hereinafter referred to as cryogenic liquid pump) for the process pump and pump production, cryogenic liquid pump in the air separation process plays an important role, The performance of cryogenic liquid pump is directly related to whether the entire set of air separation process can achieve design targets.
