Abstract
The utility model discloses a kind of water pump blade wheel gap adjusting structure, the gap between impeller and water inlet lid is in axially arranged, the gap setting gap adjust pad between water inlet lid and the pump housing.Using the structure, after water pump uses the gap increase for causing impeller and water inlet lid for a long time, simple and easy to apply by way of gap is adjusted water pump can be made to meet working condition requirement, be effectively improved maintenance work efficiency, reduce maintenance cost.
Description
Technical field
The utility model is related to pump technology field, more particularly, to a kind of water pump blade wheel gap adjusting structure.
Background technology
The impeller of conventional centrifugal water pump uses choma structure, and the gap between water inlet lid is typically radial direction,
Gap after water pump is used for a long time at impeller port ring increases, and can reduce flow and lift, will so that operating mode can not be met
Ask, subsequent maintenance usually requires to change impeller and lid of intaking, or changes corresponding choma bushing, corresponding maintenance cost
Height, and need to purchase corresponding part again, maintenance is inconvenient.
Utility model content
In view of the shortcomings of the prior art, technical problem to be solved is to provide a kind of water pump blade wheel to the utility model
Gap adjusting structure, water pump for a long time using cause impeller and water inlet lid gap increase after, can it is simple and easy to apply by
The mode of gap adjustment makes water pump meet working condition requirement, is effectively improved maintenance work efficiency, reduces maintenance cost.
The utility model is to be addressed above-mentioned technical problem by the following technical programs.
A kind of water pump blade wheel gap adjusting structure, the gap between impeller and water inlet lid is in axially arranged, water inlet
Gap between lid and the pump housing sets gap adjust pad.
Preferably, gap adjust pad is polyester film material-structure.
Preferably, the thickness of gap adjust pad is 0.2 to 0.5mm.
Preferably, gap adjust pad is provided with three to four.
The beneficial effects of the utility model：
By the way that the gap between impeller and water inlet lid is set into axial arrangement, used in long-time between causing herein
After gap increase, it can be adjusted by intaking the gap adjust pad between lid and the pump housing, it is only necessary to by gap adjusting pad
Piece is reduced accordingly, the gap between impeller and water inlet lid can just reduced, so as to easily carry out water pump gap
Adjustment, this passes through the structure of Optimal improvements, will not bring the rising of manufacturing cost, later period maintenance is simple and convenient, without zero
Part replacement, reduces maintenance management cost, and good reliability extends service life, adds the economic benefit of user enterprise.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure：1- impellers, 2- water inlet lids, 3- gaps, 4- gaps adjust pad.
Embodiment
Understand the utility model for convenience, below in conjunction with the accompanying drawings in the preferred embodiment pair of the present utility model that provides
The utility model is described in detail.
A kind of water pump blade wheel gap adjusting structure of the utility model as shown in Figure 1, impeller 1 and water inlet lid 2 it
Between gap 3 in axially arranged, the gap between water inlet lid 2 and the pump housing sets gap adjust pad 4, according to water pump
Working environment difference can accordingly by gap adjust pad 4 use polyester film material-structure, the thickness of gap adjust pad 4
It is preferred to use 0.2 to 0.5mm.When new pump is assembled, gap adjust pad 4 can pre-install three to four.Water pump, which passes through, to be used for a long time,
After gap 3 increases, gap adjust pad 4 can be accordingly reduced, reduces gap 3, so that the adjustment needs in water pump gap are reached,
It is set to meet working condition.
The utility model is not limited to above-described preferably embodiment, based on those skilled in the art institute
The known technology or use that can be known are capable of the various modifications of equivalence replacement and the embodiment of change in the prior art,
It is every to be based on spirit of the present utility model or technical concept, it should be included within protection domain of the present utility model.
