■ 概述 Summary
●D和DG型泵是卧式多级离心泵，它适合于输送清水(含杂质量小于1%，粒度小于0.1毫米)及物理化学性质类似于清水的其它液体。
D(DG) series pumps are horizontal multistage centrifugal pump, which are suitable for transporting clean water(impurity less than 1%, particle size less than 0.1mm) and other similar liquid.
●D型泵输送介质温度不大于80℃，适用于矿山排水和工厂、城市供水等场合。
D series pumps are suitable for medium temperature not more than 80°C, which are used for mine drainage and water supply for factories, cities and other places.
●DG型泵输送介质温度不大于105℃，适用于小型锅炉给水或输送热水等场合。
DG series pumps are suitable for medium temperature not more than 105°C, which are used for small boiler feed water pump or other occasions where need transport hot water.
●本系列泵性能范围(按规定点)：
This series pump performance range:
流量：6.3~500m3/h Capacity: 6.3~500 m3/h
扬程：50~650m Head:50~650m
■ 型号说明 Explanation of Model
■ 结构说明 Explanation of structure
●本系列泵为两端支承，壳体部份是节段式，泵的传动方式是通过弹性联轴器与电机联结。泵的旋转方向，从驱动端看，为顺时针方向旋转。
This series pump is supported at both ends, and the shell part is ring segment, the pump is driven through flexible coupling and motor coupling. Looking from the back of the electrical machine, the pump’s rotation direction is clockwise.
● 定子部分 Stator
主要由吸入段、中段、吐出段、导叶、填料函体等组成，并用拉紧螺栓和螺母联接成一体。吐出口均垂直向上，D型泵吸入口为水平方向，DG型泵为垂直向上。
Mainly consist of suction segment, connecting piece, discharge casing, guide vane, and stuffing body, etc. and link to one with tighten bolts and nuts. Outlet are all vertically upward, D-type pump’s inlet is horizontal, while DG-type pump’s inlet is vertically upward.
●转子部分 Rotor
主要由轴、叶轮、平衡盘及轴套等零件组成。
Mainly consist of shaft, impeller, balancing disc, and shaft sleeve parts.
●泵的密封 Sealing
◆吸入段、中段、吐出段之间的静止结合面用纸垫来密封。
Stationary joint surface such as suction segment, connecting piece and discharge casing is sealed with paper pad.
◆泵各级间采用节流密封。
Throttling seal is adopted between pump stage.
◆泵的两侧轴封采用软填料密封。
Both sides of the pump shaft seals use soft packing seal.
◆采用挡水圈挡水，防止水进入轴承。
Retaining water by retaining ring, prevent water into the bearings.
●轴承部分 Bearing parts
整个转子由轴两端的圆柱滚子轴承来支承，轴承采用油脂润滑。
The rotor is all supported by the cylindrical roller bearing on rotor sides, bearing is grease lubrication.
●平衡部分 Balancing Sets
由于叶轮前后盖板受压面积不等，要产生轴向力，此轴向力由平衡装置承担。
泵的平衡室由吐出段、填料函体，平衡水管(部件)所组成。其平衡水管(部件)不允许堵塞和用闸阀调水的流动。
As the unequal compression area of the impeller front and back cover, so produce axial force, this axial force is supported by balancing sets.
Pump balancing house consist of discharge casing, stuffing body, balancing water pipe( parts). The balance water pipe is absolutely not allowed to be blocked and make water flow with gate valve.
