进口多级锅炉给水泵/Feed water pump/德国巴赫
进口多级锅炉给水泵（欢迎选购）产品概述：
在结构上采用了卧式、多级泵分段形式，因而运行安全、平稳、噪音低、寿命长、安装维修方便。此型泵特别适用于工业锅炉给排水、冷却水输送等。也可以通过改变材质、密封形式和增加冷却系统用于输送热水、油品、腐蚀性介质等，广泛用于石油化工、热水循环、环保产业、纯净水输送等行业。
Horizontal and multi-stage pumps are adopted in the structure, so the operation is safe, stable, low noise, long service life and easy to install and maintain. This type of pump is especially suitable for industrial boiler water supply and drainage, cooling water transportation and so on. It can also be widely used in petrochemical industry, hot water circulation, environmental protection industry, pure water transportation and other industries by changing material, sealing form and increasing cooling system to transport hot water, oil products, corrosive media, etc.
进口多级锅炉给水泵（欢迎选购）运行原理：
泵壳体部分主要由轴承体、前段、中段、后段、导叶等用螺栓连接成整体，前段吸入口中线与水平垂直，也可呈水平线。后段吐出中线与水平垂直，也可呈水平线。 转子部分主要由轴及安装在轴上的叶轮、轴套、平衡盘等零件组成。轴上零件用平键和轴套螺母紧固使之与轴成为一体。整个转子由两端轴承支承在泵壳体上，转子部分中叶轮是根据泵的级数而定。转子由电机驱动，从电机端看，泵为顺时针方向旋转。 本型泵轴用滚动轴承，按型号不同而定，均不承受轴向力，泵在运行中允许转子部分在泵壳体中轴向游动，不能采用向心球轴承。轴承内用钙基黄油润换。 泵的前段、中段、后段之间密封均采用二硫化钼润滑脂润滑，转子部件部分与固定部分之间靠密封环、导叶套、填料等密封，当密封环和导叶套的磨损程度已影响泵的工作和性能时应予以即使更换。 本型泵采用填料密封或机械密封，在使用时，填料及机械密封的位置安放要正确，填料及机械密封的松紧程度必须适当，以流体能一滴一滴渗出为宜。
The shell part of the pump is mainly connected by bolts of bearing body, front, middle, rear and guide vanes. The middle line of the front suction port is perpendicular to the horizontal line, and can also be horizontal. The midline of the posterior segment is perpendicular to or horizontal. The rotor part is mainly composed of the shaft and the impeller, sleeve and balancing disk mounted on the shaft. Shaft parts are fastened with flat keys and sleeve nuts to integrate with the shaft. The whole rotor is supported on the pump housing by bearing at both ends. The impeller in the rotor part is determined by the series of the pump. The rotor is driven by a motor. From the motor end, the pump rotates clockwise. Rolling bearings are used for this type of pump shaft. They are not subject to axial force according to different types. The rotor part is allowed to move axially in the pump shell during operation, and centripetal ball bearings can not be used. The bearing is replaced with calcium-based butter. Molybdenum disulfide grease is used to lubricate the seals between the front, middle and rear secti*** of the pump. The sealing rings, guide vane sleeves and packing are used to seal the parts of the rotor and the fixed parts. When the wear degree of the sealing rings and guide vane sleeves has affected the work and performance of the pump, they should be replaced even if they are replaced. This type of pump adopts packing seal or mechanical seal. When using, the position of packing and mechanical seal should be placed correctly. The tightness of packing and mechanical seal must be appropriate. It is suitable for fluid to seep out drop by drop.
