DR型磁力驅動導熱油泵

　　DR磁力驅動導熱油泵
　　DR Magnetic Driven Heat Transfer Oil Pump

　　DR型系列泵，專用于高溫熱油加熱場合或類似的熱媒環(huán)境，選用具有較高的磁能積和極低的溫度系數，溫度穩(wěn)定性和化學穩(wěn)定性高的磁性材料，可輸送溫度至400℃的熱傳送流體，是一種理想的高溫熱油循環(huán)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.

　　該產品也可用于輸送低溫流體，應用于恒低溫場合和易結晶流體的輸送。
　　The product can also be used to transfer low temperature fluid, in applications of constant low temperature and conveying fluid likely to crystallize.

　　結構說明Description of structure

　　1.單級單吸離心式結構。
　　Single-stage single suction centrifugal structure.

　　2.安裝支撐面在泵軸心線的水平面上。
　　The mounting support surface is on the horizontal plane of the pump axial centerline.

　　3.的內部循環(huán)和冷卻散熱系統(tǒng)，保證了內置滑動軸承和磁傳動部件的使用壽命。
　　Unique internal circulation and cooling and heat dissipating system, ensuring the service life of built-in sliding bearings and magnetic driving components.

　　4.根據熱媒體溫度，必要時對內部循環(huán)液和泵支架等進行冷卻，冷卻液量每只管路0.3～0.7m3/h，壓力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.當采用外部循環(huán)液時，壓力應高于泵腔內的壓力0.07～0.1MPa，如果輸送易汽化介質時，應高于汽化壓力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.
