Description
Technical field
The utility model is related to a kind of water jet propulsion pumps, especially a kind of to be suitable for power surfboard and small lift's ships and light boats
The inexpensive water jet propulsion pump of easy maintenance.
Background technology
Power surfing and the movement of minitype motivation sport boat are since its is fabulous and effectively takes exercises and receives the happiness of people
Love, but the hydraulic propeller impeller of power surfboard and small lift's ships and light boats is inevitably touched with the sundries high speed in water
It hits, makes impeller failure；At home and abroad to be integrated design cementing or be welded on one for small-sized hydraulic jet propulsion impeller of pump and pump shaft at this stage
It rises, impeller cannot be individually replaced, need to open power hatchcover when replacing impeller, dismantle shaft coupling, and its complicated and time-consuming；And
Mainly using aluminium alloy as material, seawater corrosion resistance scarce capacity.
Invention content
In view of the above-mentioned problems, the purpose of this utility model provide it is a kind of suitable for power surfboard and small lift's ships and light boats
The easily inexpensive water jet propulsion pump of maintenance.
To achieve the above object and the technical solution adopted is that such, i.e., a kind of water jet propulsion pump, including pump shaft, leaf
Wheel, spray pump ontology, bearing block, stream guidance sealing cover and spray pump jet pipe；The pump shaft surface is fixed with axle cap；The center of the impeller
It is connect with pump shaft；The pump shaft passes through impeller and the intrinsic bearing block of spray pump, by the bolt of axle cap and bearing block by impeller
Mounted on bearing block left end；Bearing block right end is connected with stream guidance sealing cover；The spray pump jet pipe is fixed on spray pump ontology right end.
The axle cap is fixed on by fixed pin on pump shaft.
Card slot is carried on the axle cap, the impeller center is fixed with a metal insert, card is carried on the metal insert
Block；The connection type of the pump shaft and impeller is that card slot is connect with fixture block or spline connects.
Bearing block left end is equipped with bearing I and sealing ring, and right end is equipped with bearing II.
The impeller and spray pump ontology use injection molding, the bearing block to be made of corrosion-resistant metal materials.
The pump shaft right end is provided with threaded hole and is bolted；The direction of rotation phase of the thread rotary orientation of the bolt and impeller
Instead.
The spray pump jet pipe is Nian Jie with the connection type of spray pump ontology.
There are cooling water outlet and drainage by suction access port on the spray pump jet pipe.
The utility model has the advantages that：
1. using injection molding or die-casting process mode, production cost can be greatly reduced；
2. hydraulic propeller need not replace pump shaft when replacing impeller, there is no need to dismounting couplers, without beating
Piggyback pod is opened, service work is made to become easier to；
3. impeller uses engineering plastics, the enhancing of metal corrosion-resistant ability is compared.
