摘     要
 本文档提出泵属于流体机械，是一种将原动力所做的功转化为被输送流体的压力势能和动能的流体机械。螺杆泵是利用螺杆的回转来吸排液体的。螺杆与衬筒内壁紧密配合，螺杆在泵的吸入口和排出口之间就会被分隔成一个密封空间。随着螺杆的转动和啮合，密封空间在泵的吸入端不断形成，将吸入室中的液体封入其中，并自吸入室沿螺杆轴向连续地推移至排出端，将封闭在空间中的液体不断排出，犹如一螺母在螺纹回转时被不断向前推进的情形那样，这就是螺杆泵的基本工作原理。椐目前的实际应用及有关资料显示，螺杆泵的应用范围很广，它的特点是流量平稳、压力脉动小、有很强的自吸能力、噪声低、效率高、寿命长、体积小、工作可靠。突出的优点是输送介质时不形成涡流、可输送粘度范围宽广的各种介质，既可以输送各种粘度的润滑性或腐蚀性介质，也可以输送各种粘度的非牛顿液体，还可以气液混输、固液混输。它广泛应用于海上平台工程、石油化工、航运、电力、机械液压系统、建材、水利、船舶、码头、港口、油库、食品、造纸、制糖、军工和污水处理等工业部门。

65LB15-50-type screw pump design

Abstract
 This paper presents mechanical pump is fluid, is a kind of power will be the driving force behind efforts to be transmission fluid into the pressure of potential energy and kinetic energy of fluid machinery. Screw is turning to the use of screw liquid smoke emission. Screw and tube wall lining, close co-operation of the screw in the pump intake and outlet will be divided into between a sealed space. With the rotating screw and mating, sealing the space in the pump suction side evolving to inhaled enclosed room in which the liquid, and from inhalation of room along the screw axis to move from row to push the client, will be closed in the space of continuous discharge of liquid, like a nut in the thread when he was constantly turning the situation to move forward, this is the basic working principle of the screw pump. Show the practical application of current and relevant information, screw covers a wide range of applications, it is characterized by a smooth flow, the pressure pulsation of small, have a strong self-absorption capacity, low noise, high efficiency, long life, small size, reliable work. Highlight the advantage of conveying the formation of eddy current media is not to transport a wide range of viscosity of various media, we can transfer all kinds of lubricating viscosity or corrosive media, can also transport a variety of non-Newtonian fluid viscosity, but also gas-liquid mixture can lose, lose the solid-liquid mixing. It is widely used in offshore platform engineering, petrochemicals, shipping, electrical, mechanical hydraulic systems, building materials, water, ships, terminals, ports, oil depots, food, paper, sugar, military and industrial sectors, such as sewage treatment.
