Description
Technical field
The utility model is related to a kind of propeller, is specifically related to a kind of hydraulic propeller peculiar to vessel with radome fairing, belongs to
Shipbuilding industry hydraulic propeller class field.
Background technology
Hydraulic propeller is by electric-control system, the mechanical system of the pump housing, blade and radome fairing composition, and the automatically controlled life of execution
Order control hydraulic propeller is turned to and the hydraulic system of reversing is constituted.Hydraulic propeller is by motor or Diesel Driven, band movable vane
Piece rotates at a high speed, is absorbed water from water inlet, after compressed and rectification, is sprayed by nozzle at high speeds, ship is realized by reaction force
Oceangoing ship is pushed ahead.
Radome fairing is a critical component of hydraulic propeller, and current produce circumferentially rotating for high speed after blade, this
Componental movement is a consumed energy, does not produce thrust.Angled arc shaped blade is disposed with radome fairing, by current
Rotate in a circumferential direction at a high speed the current being changed into spray water backward, thrust is produced, so that useless energy is converted into significant push away
Power.The internal diameter of radome fairing is also gradually tapered up simultaneously, plays compression current, improves the effect of water flow jet speed.Therefore radome fairing
Profile, affect rectification and compression effect, largely decide the thrust and efficiency of hydraulic propeller.
Because radome fairing plays a part of compression and rectification, its profile and internal structure are complex, are mostly irregular
Arc, processing and manufacturing is difficult, but is used as the critical component of influence efficiency, fabricates precision and requires higher again.Because of profile
Complexity, conventional rectifier cover is generally cast member, the formal parameter come out according to Hydrodynamic design, makees mould and is cast.
The problem of current this structure, mainly has：
First, casting cost is high, the cycle is long：The casting of radome fairing is from the layout design of product to Mold Making, to casting
Shaping, has under higher cost and longer cycle, normal condition, and the cycle of casting is 2-3 weeks.
Second, can not finished inner surface：Due to complicated, curved surface is more, and general is difficult to rectification coarse after casting
Cover surfaces externally and internally is finished, thus influences larger inner surface but often relatively rough hydrodynamic performance, is largely effected on
Hydrodynamic performance, also influences the attractive in appearance of profile.
Third, using steel, weight is big：It is more heavy because the material of radome fairing casting is generally steel, to assembling with
Hull can all be adversely affected in itself.
Fourth, non-welding character and cutting property of wind：Casting can not be repaired with welding, and can not be cut off and removed with wind, no
Profit assembling processing.
Therefore, how to provide a kind of with low cost, efficiently accurate rectification bell-type hydraulic propeller, is that the utility model is ground
The purpose studied carefully.
