Abstract
Have the waterjet propulsor of corrosion prevention bearing, it comprises the pump housing, impeller, suction piping, water pipeline, paddle shaft, water lubricated bearing and globe thrust bearing with pump chamber; Impeller is arranged in pump chamber and is connected with rectifier, and suction piping and water pipeline are communicated in respectively the two ends of pump chamber axial direction; Suction piping is by curved the extending to form in one end of pump chamber, and the axis of pump chamber and suction piping forms acute angle; Water lubricated bearing is sheathed on respectively with globe thrust bearing the two ends that paddle shaft is relative, and water lubricated bearing is arranged at one end that paddle shaft is connected with impeller and is positioned at pump chamber, and globe thrust bearing is arranged at paddle shaft one end away from impeller.The utility model, adopts water lubricated bearing on paddle shaft, thereby effectively prevents that bearing is corroded.Meanwhile, water lubricated bearing is arranged at from impeller in the pump chamber close to, thereby has shortened cantilever, makes impeller obtain stablizing support and prevents that it from rocking.
Description
Technical field
The utility model relates to ship domain, particularly a kind of waterjet propulsor with corrosion prevention bearing.
Background technology
Waterjet propulsor together with marine powerplant, is used for propelling ship as a kind of driving tool.Existing waterjet propulsor is for corrosion prevention, and bearing is all arranged at outside pump chamber and keeps at a certain distance away with impeller.So, strengthened the moment of bearing, axle is easily shaken in operation and the application force that produces unstable.
Utility model content
For the deficiencies in the prior art, the purpose of this utility model is intended to provide a kind of waterjet propulsor with corrosion prevention bearing.
For achieving the above object, the utility model adopts following technical scheme:
Have the waterjet propulsor of corrosion prevention bearing, it comprises the pump housing, impeller, suction piping, water pipeline, paddle shaft, water lubricated bearing and globe thrust bearing with pump chamber; Impeller is arranged in pump chamber and is connected with rectifier, and suction piping and water pipeline are communicated in respectively the two ends of pump chamber axial direction; Suction piping is by curved the extending to form in one end of pump chamber, and the axis of pump chamber and suction piping forms acute angle; Water lubricated bearing is sheathed on respectively with globe thrust bearing the two ends that paddle shaft is relative, and water lubricated bearing is arranged at one end that paddle shaft is connected with impeller and is positioned at pump chamber, and globe thrust bearing is arranged at paddle shaft one end away from impeller.
One side of suction piping is provided with handle supporting seat, venting channels and bearing support block, venting channels is communicated with between handle supporting seat and bearing support block and with suction piping, handle supporting seat protrudes from suction piping surface, open sighthole for control handle, bearing support block is communicated with suction piping, and its side by suction piping extends to form vertically.
The axis of bearing support block and pump chamber is located along the same line.
The beneficial effects of the utility model:
On paddle shaft, adopt water lubricated bearing, thereby effectively prevent that bearing is corroded.Meanwhile, water lubricated bearing is arranged at from impeller in the pump chamber close to, thereby has shortened cantilever, makes impeller obtain stablizing support and prevents that it from rocking.
Brief description of the drawings
Fig. 1 is the schematic diagram of the utility model waterjet propulsor;
Wherein: 10, the pump housing; 11, pump chamber; 20, impeller; 21, rectifier; 30, suction piping; 31, handle supporting seat; 32, venting channels; 33, bearing support block; 34, control handle; 40, water pipeline; 50, paddle shaft; 60, water lubricated bearing; 70, globe thrust bearing.
Detailed description of the invention
Below, by reference to the accompanying drawings and detailed description of the invention, the utility model is described further:
As shown in Figure 1, for waterjet propulsor of the present utility model comprises the pump housing 10, impeller 20, suction piping 30, water pipeline 40, paddle shaft 50, water lubricated bearing 60 and the globe thrust bearing 70 with pump chamber 11.Impeller 20 is arranged in pump chamber 11 and is connected with rectifier 21.Suction piping 30 and water pipeline 40 are communicated in respectively the two ends of pump chamber 11 axial directions.Suction piping 30 is by curved the extending to form in one end of pump chamber 11.Wherein, both axis of pump chamber 11 and suction piping 30 form acute angle.One side of suction piping 30 is provided with handle supporting seat 31, venting channels 32 and bearing support block 33.Wherein, venting channels 32, between handle supporting seat 31 and bearing support block 33, and is communicated with suction piping 30.Handle supporting seat 31 protrudes from suction piping 30 surfaces, opens sighthole for control handle 34 is installed.Bearing support block 33 is communicated with suction piping 30, and its side by suction piping 30 extends to form vertically.Wherein, bearing support block 33 is located along the same line with the axis of pump chamber 11.
Paddle shaft 50 is connected with impeller 20 through bearing support block 33, suction piping 30 and pump chamber 11 successively.Water lubricated bearing 60 is sheathed on respectively with globe thrust bearing 70 two ends that paddle shaft 50 is relative.Wherein, water lubricated bearing 60 is arranged at one end that paddle shaft 50 is connected with impeller 20 and is positioned at pump chamber 11.Globe thrust bearing 70 is arranged at paddle shaft 50 and is installed in bearing support block 33 away from one end and the support of impeller 20.
In the utility model, on paddle shaft 50, adopt water lubricated bearing 60, thereby effectively prevent that bearing is corroded.Meanwhile, water lubricated bearing 60 is arranged at from impeller 20 in the pump chamber 11 close to, thereby has shortened cantilever, makes impeller 20 obtain stablizing support, prevents that it from rocking.
To one skilled in the art, can be according to technical scheme described above and design, make other various corresponding changes and deformation, and within these all changes and deformation all should belong to the protection domain of the utility model claim.
