Twin screw pump is sealed and unsealed two types, according to the media from one end or from both ends into the engagement space, twin-screw is divided into double-suction and single-suction two structures. Twin Screw Pump Sealed Twin Screw Pump has only two screws, but it meets all the sealing conditions. Its composition and characteristics, etc., are similar to the three screw pump, suitable for conveying clean and lubricating liquid without impurities, can be used for higher pressure occasions. Double suction structure, so that the axial force on the screw can be balanced. The pump drive gear and bearing screw bearings are located outside the pump chamber, is an external bearing structure can be used to transport poor lubrication of media, if the delivery of non-corrosive and lubricious media, you can use the built-bearing Structure, its bearings and drive gears are located in the pump chamber, thus reducing the number of pump shaft seal. Double-suction twin-screw pump, pump housing with cooling jacket, drive gearbox in the serpentine pipe through the coolant, it can be used for conveying high temperature medium. The screw pump can also be driven by a magnetic coupling, which completely eliminates leakage. It is suitable for transporting toxic, valuable or serious environmental pollution of lubricating liquid. The viscosity of the twin-screw pump medium has a great influence on the performance of the twin-screw pump. The nominal displacement of the pump refers to the displacement under certain viscosity conditions. To ensure that the pump can work under higher efficiency, The following viscosity conditions choose speed: Media viscosity cSt speed r / min 400 ~ ~ 3600 750
