摘要：近年来，随着人们对纸及其制品多样化的需求，我国的造纸行业得到了飞速的发展。在传统制浆造纸的环节中，需要用机械设备将大量的浆料输送到指定的地点，而细浆泵作为浆料输送的重要机械，在传统的造纸行业中有着举足轻重的作用。46943

细浆泵的工作原理：工作时，当电机联接细浆泵主轴从而带动前面的叶轮高速旋转，叶片带动了泵内的浆料快速的旋转，在离心力的作用下，浆液从叶轮内飞出，细浆泵内的水被排出后，叶轮的中心部分形成真空区域。由于真空，浆泵一边不停的吸入液体，一边又不停的给吸入液体一定的能量，接着将液体排出，最终完成浆料的输送工作。

我本次毕业设计的主要内容：首先，对不同结构类型的浆泵在性能、结构、工艺、可行性等方面进行综合考虑后，选择了合适的细浆泵设计方案。之后，通过计算校核了细浆泵的主要零部件之后，通过自己所掌握的专业知识及制图技能，进行了细浆泵主装配图及各个主要零件的CAD绘制。

Fine Slurry Pump Design

Abstract: In recent years, with the demand for the persification of paper and its products, the papermaking industry in China has been developing rapidly. The traditional mechanical pulping and papermaking process need to use equipment a lot to transport the slurry to the designated place. Fine pump as the slurry conveying machinery, it plays a very important role in the traditional papermaking process.

Fine slurry pump working principle is: when the motor of the pump shaft driven impeller rotates at a high speed, leaf prompted medium fast rotation, rotation of the medium under the action of centrifugal force from the impeller fly out, pump the water is drained, the central part of the impeller formed vacuum region. A constant suction of liquid, one side and constantly give the liquid to the inhalation of a certain energy, liquid discharge. Complete the delivery of the slurry.

The main content of this design is that: first of all, After the consideration of different pump's Performance, structure, process, feasibility, l chose the most suitable fine slurry pump. After calculating and checking the main parts of the pump, l draw the assembly drawing and the main spare parts of the pump through my drawing skills.
