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.的內部循環和冷卻散熱系統，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.
