双螺杆泵概述:

双螺杆泵是德国巴赫*设计理念，德国巴赫*技术，优化设计制造的具有*巴赫的双螺杆泵产品。具有高效、节能、耐磨损、寿命长、噪音低的特点。

①螺旋与螺旋间、螺旋与衬套间保持一定间隙，无机械磨损，噪音低，寿长。 
②标准结构，轴承和同步齿轮独立润滑，与输送的介质不接触，可输送润滑和非润滑介质。短轴结构可输送润滑介质。 
③具有泵体保温、密封冷却系统，适合高温介质输送。 
④高效节能，故障率低。 
⑤采用不同材料，输送不同性质物料，腐蚀性和非腐蚀性介质，可气液混输。 
⑥可实现恒压下的流量调节，适合变频控制。

双螺杆泵性能范围 
流量：0~800m3/h
压力：0~4.0Mpa
介质粘度：1~100000cst
介质温度：0~320℃（输送高温物料介质，订货时请详细说明）
介质粘度对双螺杆泵性能影响较大，泵的名义排量是指在特定粘度条件下的排量，为保证泵能在较高效率下工作，在试验不充分时，建议按下列粘度条件选择转速：　
介质粘度cSt 转速r/min 　 
＜400 1500 　 
400 ～1200 1000 　 
1200～3600 750 　　
对于粘度更高的介质，所应选用的转速和驱动电机功率，请与德国巴赫中国销售代理商。

Twin screw pump:
Twin screw pump is the advanced design concept of Germany Bach, advanced technology of Germany, the optimization of the design and manufacture of the international advanced screw pump products of the. The utility model has the advantages of high efficiency, energy saving, wear resistance, long service life and low noise.
The spiral and spiral, spiral and lining to maintain a certain gap, no mechanical wear, low noise, long life.
Standard structure, bearing and synchronous gear independent lubrication, with the transmission of the media does not touch, can be transmitted lubrication and non lubricating medium. Short shaft structure capable of conveying lubricating medium.
It has the pump body heat preservation, seal cooling system, suitable for high temperature medium.
High efficiency and energy saving, low failure rate.
The use of different materials, conveying different materials, corrosive and non corrosive media, multiphase fluid gas.
It can realize the constant pressure flow control, suitable for variable frequency control.
Double screw pump performance range
Flow: 0~800m3/h
Pressure: 0~4.0Mpa
Medium viscosity: 1~100000cst
Medium temperature: 0~320 C (high temperature material delivery medium, please specify when ordering)
Medium viscosity has great effect on the performance of double screw pump, the pump nominalcapacity refers to the specific viscosity under the conditions of the engine, to ensure that the pump can work at a higher efficiency, the test is not sufficient, recommend the following viscosity condition selection speed:
Medium viscosity cSt speed r/min
< 4001500
400 to 12001000
1200 to 3600750
For the higher viscosity of the medium, the speed should be selected and drive motor power, please contact with the German Bach China sales agents.
