2、g the clear water or the liquids which is physical and chemical similar to the clear water. It is suitable for shigh pressure boiler feed or for other high pressure water. Temperature of medium is not more than 160。二.型号说明 DESCRIPTION OF PUMP TYPEDG150-13010DG高压锅炉给水泵； DGHigh pressure boiler feed pump

3、;150流量（米3/小时）； 150Capacity (m3/h);130泵单级扬程（米）； 130Total head of single-stage;10级数； 10stage三结构 CONSTRUCTION本系列泵系分段、多级、卧式，进、出段、中段用穿杠连成一体。转子部分轴向力由平衡盘支承，用于承受由于工况变化而产生的残余轴向力，可起到有效保护平衡盘的作用。整个转子部分由泵两端的滑动轴承支承，轴承采用稀油润滑。推荐使用22号汽轮机油或N32润滑油润滑。泵吸入口、出水口均为垂直方向。泵轴封采用软填料密封或机械密封，轴封处装有可更换的轴套。泵通过弹性联轴器由电机驱动，从联轴器方向看泵为顺时针

4、方向转动。 The pump is horizontal centrifugal pump with sections and multistage. Suction casing, discharge casing, and stage casing are combined by screw bolt.The axial force of rotor assembly is supported by balancing disc, simultaneously, the rest axial force because of the change of work environment,

5、in order to protect balancing disc.The whole rotor is supported by the sliding bearing of pumps two ends. The bearing is lubricated by rare oil. 22 steamer oil and N32 lubricant are recommended.The suction and discharge are both vertical.The two ends of the pump shaft are sealed by soft packing or m

6、echanical sealing. The spare shaft sleeves are installed at the sealed ends of the pump.四.安装 INSTALLATION水泵基础不仅承受水泵动载荷，静载荷还要考虑管道的作用力，水泵基础一般应采取重型钢筋混凝土结构，不允许采用轻型结构，要充分注意刚性。泵座与基础要灌浆，基础频率应超出水泵频率范围至少20%。泵与电机校核中心必须在冷态下进行，要求轴向面偏差小于0.06毫米，径向圆偏差小于0.05毫米。泵的管道应有专门的支撑和固定，不可将其应力全部施加在泵上，以防止泵的变形。The water pump fou

7、ndation withstands not only the water pumps moving the load and the static load, but also the pipelines action. As a result, the water pumps foundation should adopt the heavy reinforced concrete structure generally, and dont allow to use the light-weight construction, to pay attention to the rigidit

8、y fully. The pump place and the foundation must be in the milk, the foundation frequency characteristic surpasses the water pump frequency range at least 20%.It must be examine the pumps and the electrical machinerys center under the cold condition. The axial surface deviation is smaller than 0.06 m

9、illimeter, and the radial direction circular deflection is smaller than 0.05 millimeter.The piping of pump should have especial support and fixation. In case of the pumps distortion, we shouldnt expose all stress on the pump.五.使用维护须知USE MAINTENANCE NOTICE1.合理暖泵是给水泵最重要的启动程序之一，可采用正暖或倒暖。采用正暖：泵即除氧器来水经入口

10、管进入泵内，由泵内压表管放水，另外在进水段下部应放水；采用倒暖：泵由压力管母管来水进入泵内，由入口管返回除氧器。另外，在吸入段下部应放水。暖泵要求为，首次启动采用正暖，备用采用倒暖，暖泵速度一般为1-2/min。Warming pump reasonably is one of most important start-up procedures. We may adopt warming or conversely warming. Adopts just warming: The pump namely comes the water inlet tube except the oxyge

11、n to enter in the pump, turns on the water by the pump intrinsic pressure table tube, moreover in enters lower part the water section to turn on the water; Adopts conversely warming: the water comes from the pressure tube female tube to enter in the pump, returns by the inlet tube eliminates the oxy

12、gen. Moreover, in inhales lower part the section to turn on the water. The warm pump request is, starts for the first time uses just warmly, spare uses but actually warmly, the warm pump speed is generally 1-2/min.2.暖泵时，应将吐出端两侧与泵座之间的联接螺栓（高压端的中心支撑点）稍松开，以消除热膨胀变形，待暖泵完成后再拧紧为启动准备。注意：未消除暖泵带来的热膨胀便投入运行将导致振动

13、。When warming up, joint bolt between two sides of discharging casing and pump place should be loosened, in order to eliminate inflation transmutation. After warming up, screwing down joint bolt prepares for starting up.Notice: running without eliminating inflation transmutation will lead to vibrate.

14、3.开泵前请灌满引水，严禁无水运转。Please fill water into pump before start. Doesnt work with no water.4.水泵在运行过程中，轴承温升不得超过环境温度35，最高温度不得超过80。When the pump is working , the bearings temperature cant exceed 35 compared to the temperature of environment. The highest temperature must under 80.5.检查泵入口压力及温度。为避免汽蚀发生，进水压力不应低

15、于汽化压力的1.13倍。实践中，当水温为105，入口压力一般为0.150.17MPa，当水温为158时，入口压力一般为0.650.7MPa。Inspect pressure and temperature of the pumps inlet. In the case of cavitation, the pressure of inlet should be higher 1.13 times than that of vaporized pressure. In practice, when the temperature is 105, generally, the pressure o

16、f inlet is about 0.150.17MPa.While its 158, the pressure of inlet is about 0.650.7MPa.6.油位，最高不得高于油窗的中心线处，过高导致润滑油泄漏，最低不低于油窗中心以下1/2处。同时检查油质，若发现有变稀、变黑、乳化等不正常现象应换油。一般情况下，首次运行200小时后换油，以后每运行1000小时换油一次。换油时整个润滑区包括油室、轴瓦用汽油清洗一遍。Oil position, the highest should lower center line of the oil window. If not, it will lead to the leakage of lubricating oil. And t
