Description
Technical field
The utility model relates to a kind of hot oil pump accessory, specifically a kind of impeller mechanism of hot oil pump.
Background technique
Hot oil pump is a kind of circular-pump or mentions delivery pump as reheating, influences the principal element of hot oil pump working efficiency
Have: 1, the gap between existing wheel nose and front pump shell is larger, the high-pressure fluid of impeller outlet and the low pressure of impeller inlet
Pressure initiation leakage between fluid, influences the output quantity of hot oil pump, efficiency is caused to reduce, since front pump shell and impeller are casting
It makes, is difficult to adjust in front pump shell and impeller to gap appropriate, on the other hand, since impeller and front pump shell material are harder,
It is difficult to finish impeller surface corresponding with front pump shell in order to be precisely controlled gap, difficulty of processing is big；2, hot oil
It pumps the cavitation occurred during the work time and seriously affects hot oil pump so that medium actual flow, outlet pressure and efficiency decline
Working efficiency, and enter impeller in medium be easy to produce whirlpool, cause medium impeller flowing when generate energy loss.Cause
This, how overcome the deficiencies in the prior art come improve hot oil pump working efficiency become urgent need to resolve the problem of.
Utility model content
In view of the deficiencies of the prior art, this application provides a kind of impeller mechanisms of hot oil pump, easy to process, effectively subtract
The amount of leakage for having lacked pumped (conveying) medium increases medium actual flow, improves the transfer efficiency of hot oil pump.
The technical solution adopted in the utility model is:
A kind of impeller mechanism of hot oil pump, including the impeller being located in pump case, it is critical that the front side of the impeller
It is provided with one group of spaced block ring, the spacing distance ecto-entad of adjacent block ring is incremented by successively, block ring and pump case
It is in the axial direction in gap setting.
3-5 spaced block rings are provided on front side of the impeller.
The inducer blade being additionally provided in the suction inlet that one group is located at pump case on the impeller, the inducer blade are
Axial--flow blading, the impeller include cricoid drive end bearing bracket, rear end cap and the main lobe being set between drive end bearing bracket and rear end cap
Piece, the block ring are arranged on the ring plain of drive end bearing bracket, and the circular hollow of front shroud is arranged in the inducer blade
It is connected smoothly in portion and with primary blades.
The inducer blade being provided on the impeller in the suction inlet that 4 are located at pump case.
The utility model has the following beneficial effects: being provided with block ring on front shroud, the face area of block ring is small, is convenient for
It is finished, the gap between block ring and pump case after finishing is more easily controlled, and guarantee makes block ring and pump case
Abrasion is not generated in the case where small―gap suture, and small gap effectively prevents medium from revealing；The spacing distance of adjacent choked flow interannular
Ecto-entad is incremented by successively, i.e. the density that is arranged at impeller inlet of block ring is low, and the density being arranged at impeller outlet is high, right
High-pressure fluid carries out intensive choked flow, prevents it from flowing at low pressure, carries out auxiliary resistance to a small amount of low-pressure fluid not being blocked
Gear, realizes the choked flow step by step to the medium for flowing to impeller inlet by impeller outlet, further prevents the leakage of medium, improve
The actual flow of hot oil pump.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is part A enlarged diagram in Fig. 1.
In attached drawing, 1 represents pump case, and 2 represent impeller, and 21 represent drive end bearing bracket, and 22 represent rear end cap, and 23 represent primary blades, 3 generations
Table block ring, 4 represent inducer blade.
Specific embodiment
A kind of impeller mechanism of hot oil pump, including the impeller 2 being located in pump case 1, it is important to, before the impeller 2
Side is provided with one group of spaced block ring 3, and the spacing distance ecto-entad of adjacent block ring 3 is incremented by successively, block ring 3 with
Pump case 1 is in gap setting in the axial direction.
Specific embodiment, as shown in Figs. 1-2, impeller 2 include cricoid drive end bearing bracket 21, rear end cap 22 and are set to drive end bearing bracket
Primary blades 23 between 21 and rear end cap 22, the block ring 3 of circular ring shape be arranged in the cricoid plane of drive end bearing bracket 21 and with it is preceding
End cap 21 is coaxially disposed, and the quantity of the block ring of setting is excessive, then not can effectively improve difficulty of processing and assembly precision, quantity mistake
The effect of at least choked flow is poor, therefore the quantity that block ring is arranged is 3-5, preferably 3, not only effectively improves processing
Difficulty and assembly precision also significantly improve the effect of choked flow, effectively prevent the leakage of medium.
The inducer blade 4 being additionally provided on the impeller 2 in the suction inlet that 4 are located at pump case 1,4 couples of inducer blade Jie
Matter is pressurized in advance, enhances the anti-cavitation performance of impeller 2, is improved the whole service life of hot oil pump, is improved hot oil pump
Whole efficiency, inducer blade 4 is axial--flow blading, the working efficiency of the induction mode of axial-flow type compared with other common inducers
Height, the inducer blade 4 are arranged in the circular hollow portion of front shroud 21 and are connected smoothly with primary blades 23, induce leaf
Piece 4 prewhirls to medium, and it is gentler to the transition of primary blades 23 along inducer blade 4 to make medium, so that into primary blades 23
Media flow it is steady, effectively reduce the generation of whirlpool, thus reduce medium impeller flowing when energy loss, improve
The working efficiency of hot oil pump, 4 circular array of inducer blade arrangement, finds, 4 inducer blades 4 can be further through test of many times
The lift and efficiency for improving pump, reduce and whirlpool occur in impeller channel, and inducer blade 4 is an integral structure with primary blades 23,
Reduce the connection types such as threaded connection, welding, assembly is simple, enhances the mechanical strength of impeller mechanism.
The utility model relates to impeller mechanism mechanical strength it is good, long service life, anti-cavitation performance is good, easy to process,
Being precisely controlled for the gap size between pump case can be further realized, medium back flow is effectively prevent, whole work efficiency obtains
To being obviously improved.
