低温液体泵撬Cryogenic pump skid
把低温液体加压到充装或气化所需压力，用于充装站、气化站与工业气体工厂。Pressurises cryogenic liquid to filling or vaporisation pressure for filling plants and gas works.
产品概述Product overview
低温泵撬的核心矛盾是“冷”和“汽蚀”。液氧 −183℃、液氮 −196℃、LNG −162℃，泵前任何一段管路吸热都会产生气泡，一旦汽蚀，泵就丢压甚至抱死。所以撬上必须做三件事：泵前管路保冷、设预冷/排气回路、把泵池与储罐的静压头算准。DWB150/1500-165 型泵撬进口 0.2–0.8 MPa、出口 15 MPa、配 67 kW 电机，双列配置一开一备。Cold and cavitation dominate: insulation, a cool-down/vent loop and correct static head. DWB150/1500-165 runs 0.2–0.8 MPa in, 15 MPa out, 67 kW, dual train.
充装站场合，泵后接高压气化器与充装排；气化站场合，泵用于把液体送进中压气化器。两种流程的泵型、密封与控制逻辑不同，不能互换。Filling plants need a high-pressure vaporiser and manifold after the pump; stations feed a medium-pressure vaporiser instead.
