关于螺杆泵你知道多少？

螺杆泵工作原理是利用螺杆的回转来吸排液体的。中间螺杆为主动螺杆，由原动机带动回转，两边的螺杆为从动螺杆，随主动螺杆作反向旋转。
The working principle of the screw pump is to use the rotation of the screw to suck out the liquid. The middle screw is the active screw, which is driven by the prime mover to rotate. The screw on both sides is the driven screw, which rotates inversely with the active screw.
各螺杆相互啮合，螺杆与衬筒内壁紧密配合，在泵的吸入口和排出口之间， 就会被分隔成一个或多个密封空间。随着螺杆的转动和啮合，这些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，将封闭在各空间中的液体不断排出。
Each screw meshes with each other, and the screw closely matches the inner wall of the liner barrel. Between the suction port and the discharge port of the pump, the screw is separated into one or more sealing spaces. With the rotation and meshing of the screw, these sealing spaces are formed at the suction end of the pump. The liquid in the suction chamber is sealed in the suction chamber, and is continuously moved from the suction chamber along the axial direction of the screw to the discharge end, and the liquid enclosed in each space is continuously discharged.
螺杆泵的优点：
The advantages of the screw pump are:
1、压力和流量范围宽阔；
1, wide range of pressure and flow;
2、运送液体的种类和粘度范围宽广；
2, the type and the viscosity range of transporting liquid are wide.
3、因为泵内的回转部件惯性力较低，故可使用很高的转速；
3, because the inertia force of the rotary parts in the pump is low, it can use very high speed.
4、吸入性能好，具有自吸能力；
4. Good inhalation performance and self absorption ability.
5、流量均匀连续，振动小，噪音低；
5. Uniform and continuous flow, low vibration and low noise.
6、与其它回转泵相比，对进入的气体和污物不太敏感；结构坚实，安装保养容易。
6. Compared with other rotary pumps, they are not sensitive to the gas and dirt entering them; they have a solid structure and are easy to install and maintain.
