Scope of application:
The 2W · W series sealed twin-screw pump is suitable for conveying without being affected by the medium. The sealed positive displacement rotary pump forms sealed cavities in the pump body through the mutual meshing of the main and driven screws in the pump body, as well as the cooperation between the screws and the pump body holes. When the screws rotate, these sealed cavities continuously move forward, pushing the liquid in the sealed cavities to be discharged from the outlet 150 ℃, viscosity: 3-760mm²/s. Pressure: 0.6-6.3Mpa. Flow rate: 0.6-570m³/H.
Structural features:
This type of pump adopts a double suction structure, with both ends of the screw in the same pressure chamber, and the force on the shaft can be balanced by itself. The bearings at both ends are externally mounted and separately mounted, lubricated with lubricating oil (grease). The two screws are driven by a pair of synchronous gears, and there is no contact between the screw teeth, leaving a small gap. Impurities in the medium cannot directly wear the screw teeth. There are two types of import and export methods: one is horizontal entry and horizontal exit, and the other is horizontal entry and vertical exit. Users can make their own choices according to their needs.
