螺杆泵有哪些优点

　　螺杆泵有哪些优点？
　　What are the advantages of screw?

　　1)压力和流量范围宽阔。压力约在3.4-340千克力/cm 2，流量可达18600cm3/分；
　　1) The wide range of pressure and flow. Pressure of about 3.4-340 kgf / cm 2, flow rate of up to 18600cm3 / min;

　　2)运送液体的种类和粘度范围宽广；
　　2) The delivery of the liquid type and a wide viscosity range;

　　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 of the rotary pump parts, lower inertia, it can use a high speed;

　　4)吸入性能好，具有自吸能力；
　　4) Inhalation of good performance, with self-absorption capability;

　　5)流量均匀连续，振动小，噪音低；
　　5) The flow uniformly continuous, little vibration, low noise;

　　6)与其它回转泵相比，对进入的气体和污物不太敏感；
　　6) when compared with other rotary pumps, gas and dirt entering the less sensitive;

　　7)结构坚实，安装保养容易。7) The structure of a solid, installation and maintenance easy.
