　　Batte Machinery Zhengzhou Co.,Ltd. for your Weapon: How to improve the extrusion gear pump NPSH efficiently?

　　We can according to the extrusion gear pump selection, pump selection and use of the site and other conditions, a comprehensive analysis, appropriate to the application, thereby improving the extrusion gear pump effectively improve NPSH, as follows:

　　First, the increase in extrusion gear pump storage tank before the liquid level in the pressure to increase the effective NPSH.

　　Second, to reduce the suction on the mounting height means extrusion gear pump.

　　Third, the suction device instead intrusion device, the medium extrusion gear pump can be gravity fed to the pump inlet.

　　Fourth, reduce flow loss pipeline before the extrusion gear pump. As far as the requirement to shorten the pipeline, reducing the flow rate of the pipeline, reducing elbows and valves, try to increase the valve opening degree.
