SPG型屏蔽泵

特点: Features 全封闭式、无轴封（只有静密封而无动密封）的独特结构保证机组决不泄漏； 封闭的自循环结构可输送任何介质而保证不对环境造成污染； 采用全新的低转速屏蔽电机及介质循环系统保证机组低振动、低噪音、低温升； 泵体采用管道式结构，其进出口径相同且位于用一直线上，能像阀门一样安装在管道的任何位置，方便、快捷、稳固； 无轴封、无滚动轴承、无需维护、运行可靠； 使用隔振垫、隔振器及金属波纹管等隔振装置后其震动更小、噪音更低； 独特的安装结构大大缩小了泵的占地面积，可节约基建投资40%以上。 Particular and fully cased structure without shaft sealing (there is only a static sealing but no dynamic sealing ensures a high quality sealing of the machine) Closed self-circulation structure is suitable for transporting any sort of liquid without any pollution to environment; Entirely new and low speed cande cande motor as well as liquid circulation system ensures a low vibration, noise and temperature-rise of the machine. Pipe structure, similar inlet and outlet diameters are on the same line which can be fixed at any place on the pipe just like valves, convenient, quick and stable. Pump has no shaft seal and rolling bearing, so it needs no maintenance and operation is dependable. Lower vibration and noise due to vibration devoices such as vibration cushion, this saves capital construction invest by 40% and over. 用途 Applications 建筑物空调系统冷水循环； 建筑物空调系统冷冻水循环； 建筑物空调系统热水循环； 厂矿封闭回路中冷热水循环； 建筑物生活及消防用水； 变换材质可广泛使用于石油、化工、制药、食品、制冷及原子能等行业； Cold water circulation, cooling water circulation or hot water circulation in air-conditionings system of buildings; Cold or hot water circulation in close way back system of factory and mine; Water used for life of fire fighting of buildings; It can be widely used in industries such as oil, food, refrigeration and nucleates.
