Abstract

The invention provides a high-speed water spraying propeller. According to the overall structure, the propeller is composed of a central impeller shaft and a propeller body shell. The central impeller shaft is structurally an integral cone, and the front and the back of the central impeller shaft are each provided with a fairing. The impeller shaft is provided with blades which are increased step by step from a water inlet to a water spraying opening, the propeller pitches of all layers are increased step by step, the spacing among all layers is increased step by step, and flow deflectors are arranged among all layers.

Description

A kind of high-speed spray screw
Technical field
The present invention relates to naval vessel hydro-jet propulsion system technical field, be embodied in a kind of naval vessel high-speed spray screw.
Background technology
It is that the conventional axial-flow pump of two-stage pressurizes and the water spray thrust of generation that current naval vessel hydro-jet propulsion system adopts, this kind of designThe hydraulic pressure (current) obtaining still can not very large being enhanced, and it is very large to suck the water yield in cabin, and the pipeline of setting is more,Increase undoubtedly the load weight on naval vessel self. Due to above various reasons, the navigation on naval vessel is still quick not.
Summary of the invention
The naval vessel high-speed spray screw that provides a kind of thrust very large is provided technical problem to be solved by this invention, will adoptRealize by following technical scheme.
As shown in figure (1): (five layers of embodiment) naval vessel high-speed spray screw overall structure is: it by center impeller axle andOar body case composition. Impeller shaft rear and front end is respectively equipped with kuppe (in order to reduce eddy current effect), is installed by front end water inletThrust bearing and rolling bearing support, and rear end install rolling bearing support be fixed in oar body case. In order to eliminateCavitation phenomena, water spray screw entirety is reduced to every layer of blade area of water jet is corresponding gradually by water inlet. In order to prevent currentIn high-speed spray screw, rotation causes lower one deck blade water-taking efficiency step-down, on oar body inwall, axial direction bar shaped is installedDeflector. Every layer of single deflector narrowed to water jet by water inlet step by step to the effect interface of current. Water jet place arcHood inwall is equally also provided with the deflector of bar shaped.
Impeller shaft structure: the front end water inlet diameter of axle is little, and blade is large, the rear end water jet diameter of axle is large, blade is little, every layer of blade itBetween spacing as figure (3) as shown in, be mainly for spatial volume between ensureing every layer equate. And the design of blade is from water inletAlso have following characteristics to water jet: the blade of every layer increases gradually, pitch and helical angle be increasing (pitch: every leaf alsoThe spiral distance that sheet rotates a circle). This kind of design is in the time that impeller shaft rotates one week, and the overall pitch of every layer of blade becomes large gradually(need carry out by experiment to determine the concrete numerical value of pitch), more and more faster to guarantee flow velocity.
The operation principle of naval vessel high-speed spray screw: when screw is in the time rotating, first floor blade sucks current, due to waterPressurizeed by spirality, then flow to next stage blade after axial diversion plate water conservancy diversion, now current have had initial velocity, same therewithTime, every layer of blade is all same synchronous working, and the speed of current (hydraulic pressure) blade quantity, the pitch of helical layer oar therewithAnd be proportional relationship by the pressure of water suction stream, the design of this kind of blade quantity also will be from the thermal efficiency and propulsive efficiency two certainlyAspect considers, and the best way is exactly that the front end of second blade and the rear end of first blade align.

Detailed description of the invention
(1) high-speed spray screw monolithic case (as shown in figure (2)) is arranged on hull, and monolithic case comprises: oar bodyArc hood 1., the deflector of arc hood inwall 2., oar body case 3., water jet rolling bearing support (not shown). TheyThat disposable casting is as a whole.
(2) impeller shaft (as shown in figure (3)) comprises: the major flow cover of water jet 4., the cone axis of the blade that is of five storeys 5., itCan cast as a whole.
(3) integral wheel axle is inserted on the support of bearing of the water jet in oar body by oar body case water inlet, thenThe kuppe (not shown) of axle head installs.
(4), in water inlet, the support that thrust bearing and rolling bearing are installed is inserted to axle head, and be fixed by bolts toOn oar body water inlet shell.
(5) every layer of interlobate deflector need be fixed by bolts in oar body case.
(6) finally water inlet kuppe (not shown) is installed.

Claims (4)

  1. The present invention is a kind of high-speed spray screw, and its principal character is as follows:
    1. its impeller shaft is cone, and becomes gradually large by water inlet to the water jet diameter of axle.
  2. 2. Multi-layer propeller (being at present 5 layers) is set on impeller shaft, and the spacing between every helical layer oar is increasing, every layerBlade quantity increases step by step.
  3. 3. the helical angle of every layer of blade and pitch become large step by step.
  4. 4. the oar body case inwall between every layer of blade is all equipped with deflector, and last water jet arc hood inwall is sameBar shaped deflector is also housed.
