Technical field
The utility model belongs to power machine, relates generally to a kind of fluid and carries and propulsion machineries.
Background technology
At present, for the screw propeller class aqueous fluid propelling unit on boats and ships, for the screw propeller aerial propeller on aviation aircraft, and all kinds of liquid propellers or the conveyer such as prerotator, due to the deficiency on structure design, when screw propeller assembly or the operation of blower impeller assembly high speed rotating, under blade or fan blade Fan are moving, be positioned at the part water body of blade or fan blade operating area or gas under inertial flow effect, form the rotating current of high-speed plane or air-flow, axial flow pressure and speed significantly decline, displacement or free air capacity obviously reduce, operating efficiency is low, the waste of the energy and loss are large.
Summary of the invention
The purpose of this utility model is exactly the problem existing for above-mentioned prior art, and design provides a kind of pressure flow-guiding type liquid propeller of new construction, reaches applied widely, operating efficiency is high, reduce the object of consumption of power.
Basic Design of the present utility model is:
1., force flow-guiding type liquid propeller to comprise main power machines and be packed in the main impeller assembly on main power machines, in the outside of main power machines and main impeller assembly, surround equipped cylindrical shell, on cylindrical shell inside portion, be positioned at the relative position of main impeller assembly fixedly impeller assembly be installed, the stationary blade of described fixedly impeller assembly is the helix angle opposite direction with respect to tubular axis with respect to the helix angle direction of tubular axis and the primary blades of described main impeller assembly.
2., force flow-guiding type liquid propeller to comprise main power machines and be packed in the main impeller assembly on main power machines, in the outside of main power machines and main impeller assembly, surround equipped cylindrical shell, the secondary engine configuration that is fixedly mounted with accessory impeller assembly is arranged in cylindrical shell, and accessory impeller assembly is relative with main impeller assembly, the back blades of described accessory impeller assembly is the helix angle opposite direction with respect to tubular axis with respect to the helix angle direction of tubular axis and the primary blades of described main impeller assembly, and described secondary engine hand of rotation is contrary with described main power machines hand of rotation.
The utility model adopts forces diversion mode to be realized liquid or the quick mode of movement of gas, realize the raising of boats and ships and aircraft counteraction propulsive force and blower fan axial exhaust operating efficiency, can be widely used on boats and ships, aircraft and prerotator, have that structure design is new reasonable, operating efficiency is high, save consumption of power, use cost reduces, the feature of applied range.
