DR型磁力驱动导热油泵

　　DR磁力驱动导热油泵
　　DR Magnetic Driven Heat Transfer Oil Pump

　　DR型系列泵，专用于高温热油加热场合或类似的热媒环境，选用具有较高的磁能积和极低的温度系数，温度稳定性和化学稳定性高的磁性材料，可输送温度至400℃的热传送流体，是一种理想的高温热油循环泵。
　　DR series pumps are specially designed for applications with high temperature hot oil heating or similar thermal media environment; they are made with magnetic materials with high magnetic energy product and extremely low temperature coefficient, and high temperature and chemical stability, to transfer heat transfer fluid with temperature up to 400℃, hence an ideal high temperature heat transfer oil circulating pump.

　　该产品也可用于输送低温流体，应用于恒低温场合和易结晶流体的输送。
　　The product can also be used to transfer low temperature fluid, in applications of constant low temperature and conveying fluid likely to crystallize.

　　结构说明Description of structure

　　1.单级单吸离心式结构。
　　Single-stage single suction centrifugal structure.

　　2.安装支撑面在泵轴心线的水平面上。
　　The mounting support surface is on the horizontal plane of the pump axial centerline.

　　3.的内部循环和冷却散热系统，保证了内置滑动轴承和磁传动部件的使用寿命。
　　Unique internal circulation and cooling and heat dissipating system, ensuring the service life of built-in sliding bearings and magnetic driving components.

　　4.根据热媒体温度，必要时对内部循环液和泵支架等进行冷却，冷却液量每只管路0.3～0.7m3/h，压力0.2～0.3MPa。
　　The internal circulating liquid and pump supports are cooled when necessary according to the temperature of hot media, with cooling liquid flow of 0.3~0.7m3/h per pipe, at a pressure of 0.2~0.3MPa.

　　5.当采用外部循环液时，压力应高于泵腔内的压力0.07～0.1MPa，如果输送易汽化介质时，应高于汽化压力0.175～0.2MPa。
　　When external circulating liquid is used, the pressure should be 0.07~0.1MPa higher than that within the pump cavity, or 0.175~0.2MPa higher than the vaporizing pressure if media likely to vaporize is conveyed.
