D155-30x4d型多级泵@珠海D155-30x4d型多级泵
如真空过滤，真空引水，真空送料，真空蒸发，真空浓缩，真空回潮和真空脱气等，多级泵得到广泛的应用。可抽除易燃，易爆的气体，此外还可抽除含尘，含水的气体，因此，水环泵应用日益增多。
可供输送不含固体（磨料）、不含悬浮物的清水或物理化学性质类似于清水的其它液体之用。也可通过改变泵的材料（或泵过流部分的材质）、密封形式或增加冷却系统用于输送热水、油类、腐蚀性或含磨料的介质等。
D型泵系卧式、单吸、分段式多级离心泵，吸入口为水平方向，吐出口为与水平垂直向上。泵的进水段、中段、出水段、轴承体等泵壳体部分通过拉紧螺栓联成一体，并根据泵的扬程选择泵得级数。（可根据用户需求变换水泵进出口方向）该系列泵转子部分组还要由轴及安装在轴上的叶轮、轴套、平衡盘等零件组成，其中叶轮的数量根据泵的级数而定。轴上零件通过平键和轴螺母紧固使之与轴联成一体。整个转子由两端滚动轴承或滑动轴承支承，轴承按型号不同而定，均不承受轴向力，其轴向力由平衡盘平衡。泵在运行中允许转子在泵壳中轴向游动，不能采用向心球轴承。滚动轴承用油脂润滑，滑动轴承用稀油润滑，并用油环进行自润滑，循环水冷却。jdhuiquan6.24

c将该留下来的该泥浆和液体沿轴向从该室排除，并将其喷入一多级离心泵的进口；d利用从该多级离心泵出来的物料作为形成该涡流的喷射液体；因此，该大尺寸的物料移向该涡流的外圆而被排出，结果，当多级离心泵用来泵送液体中含大尺寸至小尺寸物料的泥浆流时小，尺寸的物料和液体被喷入该多级离心泵，因此，降低了该叶轮的磨损，并允许该泵高速运转，因而效率提高。
泵的进水段、中段、出水段之间的密封面均采用二硫化钼润滑脂密封，转子部分与固定部分见装有密封环、导叶套等进行密封，当密封环和导叶套的磨损程度已影响泵的工作性能时应予更换。轴的密封形式有机械密封和填料密封两种。泵大多采用填料密封，DF、DY型泵一般采用机械密封。泵采用填料密封时，填料环的位置安放要正确，填料的松紧程度必须适当，以液体能一滴一滴渗出为宜。泵各种密封元件装在密封腔内，腔内要通入一定压力的水，起水封、水冷或水润滑作用。在轴封处装有可更换的轴套，以保护泵轴。

工作原理多级泵是离心泵的一种。常见故障编辑故障一水泵不吸水压力表和真空表指针剧烈跳动原因：1.灌注引水不够2.管路与仪表联接处漏气3.吸程过高解决方法：1.检查底阀是否漏水.再雇足引水2.拧紧漏气处3.降低吸水高度故障二水泵不吸水真空表表示高度真空。原因：1.底阀没有打开或己堵塞2.吸水管路阻力太大3.过滤器堵塞解决办法：1.检査底阀2.更换吸水3.清理过滤器故障三压力表有压力但仍不出水原因：1.出水管阻力太大2.旋转方向不对3.出口管阀门未开4.叶轮堵塞。
The pumps are driven directly by the primer through an elastic coupling. From the direction of the prime mover, the pump rotates clockwise.
1. Type D: Type D pump for the transport of water without solid particles, temperature slower than 80 degrees C of clean water or physical and chemical similar to clear water liquid, suitable for mining or urban water supply and drainage works.
Type D pump for delivery temperature of -20 c to 105 degrees C, no solid particles of corrosive liquid, can also be used as a second high-pressure boiler for water pump, pump import allowed pressure of 0.6MPa. The user can choose the material of the pump, seal form, structure of the pump and determine the capacity of the motor according to the name, concentration, pump import pressure, use temperature and so on.
The D-pump is used to transport oil and petroleum products with a temperature of -20 c to 105 degrees C, with a viscosity of less than 120 percent.
The D-pump is used to transport mine water and similar liquids containing a small amount of solid particles with a particle diameter of less than 0.5mm and a temperature of less than 80c.
Type D pump for the transport of non-solid particles, temperature below 105 degrees C of clean water, or physical and chemical similar to the liquid of clean water, suitable for medium, hot water-like medium and medium and low pressure boiler water supply or transport hot water and class.
