Description
Technical field
It is a kind of adjustable Turo pump without phyllocyst gap impeller of band the invention mainly relates to fluid machinery.
Background technology
Turo pump is mainly used in pumping complex dielectrics or impurity containing fluid, such as two-phase fluid containing rubbish, chopped fiber material or excrement,
But the efficiency of pump is also ensure that simultaneously, and pump suction performance is good.The operation principle of Turo pump be when the impeller is rotated medium by centrifugal force
Effect energy increase, moved into interlobate medium by the promotion of blade together with impeller.In impeller outlet near top
Medium forms insertion stream because centrifugal force is larger, and the medium in the middle part of impeller forms recycle stream.Insertion flows through pump chamber outlet outflow,
Form certain lift；Solid particle and fiber in medium obtain energy in the presence of recycle stream, and the overwhelming majority is without leaf
Wheel, and without in phyllocyst move after discharged through pump discharge so that reach conveying complex dielectrics or impurity containing fluid purpose.Research
It was found that be influence one of main parameter of Turo pump performance without phyllocyst gap L, increase pump without phyllocyst gap, the non-blocking of pump
Can improve, efficiency declines, reduce pump without phyllocyst gap, the nonblocking performance of pump declines, lift increase, efficiency rise.And
, it is necessary to which according to actual conditions change Turo pump without phyllocyst gap L, traditional method is exactly to pass through in many application scenarios
Change the position adjustments of axle step without phyllocyst gap (because the presence of key, it is impossible to adjusted by mounting sleeve), this adjustment
Method without phyllocyst gap undoubtedly brings the increase for the cumbersome and cost installed.The present invention provides a kind of regulation without phyllocyst gap
Method, no phyllocyst gap is adjusted by adjusting the length of impeller hub.
The content of the invention
It is an object of the invention to provide regulation method of the Turo pump without phyllocyst gap leaf, adjusted by adjusting the length of impeller hub
Without phyllocyst gap.
The present invention is a kind of adjustable Turo pump without phyllocyst gap impeller of band, and it is mainly by impeller nut (1), protecgulum (2),
Wearing plate (3), the pump housing (4), impeller (5), wheel hub adjustable apparatus (6), bonnet (7), main shaft (8) is filled out
Expect the composition such as gland (9).It adjusts the principle without phyllocyst gap：Wheel hub adjustable apparatus is housed on vortex pump impeller (5)
(6), it is connected through a screw thread, rotary hub adjustable apparatus (6) adjusts Turo pump without phyllocyst gap L；By changing rotation
The structure for flowing impeller of pump uses hub length adjustable impeller, and it is made up of impeller (5) and wheel hub adjustable apparatus (6), leaf
Taking turns (5) and wheel hub adjustable apparatus (6), directly connection screw thread is fine thread, is passed through rotary hub adjustable apparatus (6)
Scope of the regulation without phyllocyst gap is 0~0.3L1；Wheel hub adjustable apparatus (6) is circular interior staircase structural model, and in interior round platform
On be uniformly distributed multiple keyways, fixation can be may also function as by key.
Prior art is contrasted, beneficial effects of the present invention are as follows.
The present invention mainly overcomes traditional Turo pump without phyllocyst gap is non-adjustable or the problems such as high adjustment cost, to vortex pump impeller knot
The improvement of structure, no phyllocyst gap can be adjusted by adjusting the length of impeller hub, the Turo pump of this design method is employed,
The hydraulic performance or blocking-free performance energy of Turo pump can be accepted or rejected according to actual scene adjustment Turo pump without phyllocyst gap.
Brief description of the drawings
Fig. 1 is the adjustable structural representation without phyllocyst gap Turo pump of the present invention；
Fig. 2 is the structural representation of hub length adjustable impeller of the present invention
Fig. 3 is the structural representation of wheel hub adjustable apparatus of the present invention；
Embodiment
Referring to the drawings shown in 1, this is adjustable to be mounted in underwater operation without phyllocyst gap Turo pump, by bearing body support frame by the water
Pump is arranged on the support of platform (support height can adjust) and (not provided on figure), so allows when mounted according to reality
Need to adjust position of the Turo pump on underwater platform and play a supportive role, delivery port connects with fixing pipeline, and one is served to pump
Determine fixation.
Referring to the drawings shown in 1, it is mainly by impeller nut (1), protecgulum (2), wearing plate (3), the pump housing (4),
Impeller (5), wheel hub adjustable apparatus (6), bonnet (7), main shaft (8), the composition such as gland (9).It is adjusted
Principle without phyllocyst gap is：Wheel hub adjustable apparatus (6) is housed on vortex pump impeller (5), is connected through a screw thread, is rotated
Wheel hub adjustable apparatus (6) adjusts Turo pump without phyllocyst gap L；Hub length is used by the structure for changing vortex pump impeller
Adjustable impeller.The submersible motor of the pump drives the high speed of double-entry impeller (3) to rotate by main shaft, the medium entered from water inlet
By the effect energy increase of centrifugal force, moved, gone out in impeller together with impeller (5) by the promotion of blade into interlobate medium
The medium of mouth near top forms insertion stream because centrifugal force is larger, and the medium in the middle part of impeller forms recycle stream, and insertion is flowed through
Pump chamber outlet outflow, the impurity formed in certain lift, medium obtains energy in the presence of recycle stream, the overwhelming majority without
Cross impeller, without in phyllocyst move after discharged through pump discharge.
Fig. 2, shown in 3, it is primarily characterized in that：Hub length adjustable impeller is by impeller (5) and wheel hub adjustable apparatus (6)
Directly connection screw thread is fine thread for composition, impeller (5) and wheel hub adjustable apparatus (6), adjustable by rotary hub
Scope of device (6) regulation without phyllocyst gap is 0~0.3L1；Wheel hub adjustable apparatus (6) is circular interior staircase structural model, and
Multiple keyways are uniformly distributed on interior round platform, fixation can be may also function as by key.
