Description

A kind of conduit type marine propeller
Technical field
The present invention relates to a kind of marine propeller, particularly relate to a kind of conduit type marine propeller.
Background technology
Marine propeller of a great variety, common ship for civil use screw propeller mainly contains conventional propeller, shrouded propeller, adjustable pitch propeller.
Conventional propeller is made up of blade and propeller hub.Screw propeller and ship axle coupling part are called propeller hub, and propeller hub is the bullet of a butt.In order to reduce resistance in screw propeller water, install hub cap in propeller hub rear end, hub cap forms streamline contour together with propeller hub.Conventional propeller Chang Weisan leaf or four leaves, blade is fixed on propeller hub.Be called blade face by the one side of propeller blade seen during eyes front after stern, another side is called blade back.Blade and propeller hub connection place are called blade root, and the outer end of blade is called blade tip.When the positive car of screw propeller rotates, above, person is called guide margin at blade edge, and another side is called lagging edge.
Shrouded propeller installs a sleeve outward at conventional propeller.Sleeve can be fixing, is called A/C.Sleeve also can be rotate, and is called steering nozzle.The generally shrouded propeller of steering nozzle, its screw propeller rotates along the axis of level, and steering nozzle then rotates along vertical axis.Steering nozzle, except playing guide functions, also plays a part rudder.According to the influence of conduit convection cell speed, conduit is divided into again acceleration duct (also claiming step-down catheter) and decelerating duct (also claiming flaring conduit), the cross section of fluid channel of acceleration duct inside is the shape of convergent from front to back, and the cross section of fluid channel of decelerating duct inside is the shape of flaring from front to back.A/C and steering nozzle all do not rotate together with screw propeller.The spacing of pipe inner wall and blade tip is very little, and foreign material blocking and pipe inner wall and blade tip stator scrapping rotor easily occur.
All marine propellers all can produce steam bubble at the blade tip place of blade back, and this process is called cavitation, and cavitation can produce noise and vibration, reduce the performance of screw propeller.Cavitation can cause propeller material to damage, and is called cavitation corrosion, also claims cavitation or cavitation erosion.In order to reduce the harm of cavitation to the Military Ship such as submarine, warship, torpedo and equipment, often adopt large skew back seven vane propeller, pump water propelling screws, waterjet propulsor and composite propeller.Technical sophistication, the cost of large skew back seven vane propeller, pump water propelling screws and waterjet propulsor are high, are more difficultly applied to ship for civil use.
Tugboat, trawlboat, the propeller load weight of the ships for civil use such as marine engineering job platform, the blade face of blade and the pressure reduction of blade back very large, if do not have conduit to limit, higher-pressure region water can stream to meiobar, produce power is lost, if install conduit additional, adopt A/C screw propeller, although the efficiency of screw propeller can be made to improve, but the turning radius of boats and ships increases, make convolution performance and the low speed rudder deleterious of boats and ships, according to rudder propeller, although rudder propeller also has the effect of rudder, but tugboat, trawlboat, work at the low rotational speed in the ship for civil use most time such as marine engineering job platform, operating mode is complicated, the stability requirement of marine operation to navigation is high, higher to the thrust requirements of screw propeller.
Along with the increase of larger-sized vessel and the speed of a ship or plane, the load of screw propeller is larger, existing propeller for vessels due to blade point stream loss, screw propeller after wake flow contraction etc. make its propulsion coefficient not high, and in prior art, screw propeller breaks down not easily Timeliness coverage, therefore needs to improve existing propeller for vessels.
