1.5GCJ-5 型单吸多级分段式离心泵，供输送 110 ℃以下的清水及物理化学性质类似于水的液体，适用于锅炉给水、工厂和城市给水等。
1.5 ——吸水口直径（毫米）被 25 除得值并化整
G ——锅炉给水泵
C ——表示泵的种类
J ——机械密封式
5 ——缩小为 1/10 泵的比转数。即泵的比转数为 50
6 ——叶轮的数量
General Description
Type 1.5GCJ pump is centrigugal pumps of single suction and multi-stage segmental type which can be used to transport clean water and liquids with physical and chemical nature similar to water.The liquid temperature is not higher than 110 ℃ .It is suitable for water feeding to boilers,ａnd water supplying to factories and cities.
Designation of 1.5GCJ — 5 × 6
1.5 —— Suction diameter(mm)divided by 25 , and then change the Value into integer
G —— Boiler feed pump
C —— Indicating type of te pump
J —— Mechanical seals
5 —— Specific speed divided by 10 (i.e.the specific speed of the pump is 50)
6 —— Number of impellers

结构说明 Construction
泵的进出口方向均垂直向上，为根据所需扬程选用不同级数。
泵的定子部分由进水段、中段、出水段、尾盖和轴承体等零件组成。
泵的转子部分由轴、叶轮、轴套和平衡盘等零件组成，两端支撑在滚珠轴承上。
泵的进水段、中段、出水段静止结合面采用纸垫通过紧螺栓的拉紧来达到密封。为防止水进入轴承、在轴套间装有“○”形密封圈。泵体两端轴封采用机械密封。
泵两端轴承体有环形冷却室。当被输送液体大于 80 ℃时，应通入冷水，对轴承进行冷却。
轴承内的钙基黄油润滑脂可通过油杯注入。
从进水段方向看，泵为顺时针转动。
The directions of suction and discharge of the pump are all vertical and upward .with different stages selected according to the needed head.
Stator of the pump is composed of suction casing .mid-segment.discharge casing .end cover and bearing body.
Rotor of the pump is composed of shaft.impellers.sleeves,ａnd balancing disk,The two ends are supported by the ball-bearings
Paper gaskets are used on the contacting surfaces between the suction casing.mid-segment and discharge casing of the pump.They are sealed by tightening the bolts. ○ -rings are mounted on the interfaces between the sleeves to prevent water from entering the bearnjngs. ○ ilimmersed machine is sealing at the two ends the pump.
There are water cooling jackets around the bearing housings.when the temperature of liquid is higher than 80 ℃ ,Cooling water should be turned on to cool the bernings.
Calcium grease lubricant is firled into the bearing thrugh oil-cups.
Viewing from the direction of the suction casing .the pump is rotating clockwise
