Technical Information

China HW and HM Series double screw pump:

Double-suction double screw pump is mainly made up of driving shaft and driven shaft as well as synchronizer gears installed on them respectively. Each shaft is equipped with a pair of scroll covers having reverse directions of turning. The driving shaft transfers impetus to the driven shaft through synchronizer gear. Therefore there is no metal touch between scroll covers with intermeshing engagement on the driving and driven shafts.
When the pump is running,a sealed chamber with invariable capacity will be formed between the scroll covers with intermeshing engagement on the driving and driven shafts and the pump body or bushing. Fluid media in the pump chamber entering from the suction flange flows evenly to the both ends of screw shaft. The both are finally transmitted to the delivery side of pump after joining together,which achieves the goal of pump delivery.
