WATER JET PROPULSION UNIT FOR DISPLACEMENT TYPE SH 优质文献 相似文献Nozzle optimization for water jet propulsion with a positive displacement pump In the water jet propulsion system with a positive displacement(PD) pump, the nozzle, which converts pressure energy into kinetic energy, is one of the...
The drive for the impeller is inserted into the thrust housing from above through a cover plate, and the thrust housing is closed at the bottom by a base plate which has a water inlet, arranged concentrically in the centre, for the axial flow of water against the impeller and at least ...
A water-jet propulsion system for ships, which are intended to be used in shallow waters. A semi-axial, bladed turbine wheel with a vertical axis of rotation is disposed so that it can rotate in a well- shaped pressure housing. Into the pressure housing, the driving mechanism for the turb...
