Abstract
The utility model discloses a high efficiency single stage pump, including the pump body, motor, pump cover, install the impeller in the pump body, the pump shaft is connected with motor drive, and the impeller import department that is located the below of pump shaft is equipped with the water guide awl, and the central line of water guide awl is the same with the central line of impeller, and the high H who imports apart from the impeller on the water guide awl is equivalent to impeller inlet diameter D0's fifth, and the diameter d of water guide awl lower extreme is equivalent to impeller inlet diameter D0's third, and the water guide awl passes through with pump body adoption R5 fillet, and the tapering of water guide awl is 1: 5. Adopt the utility model discloses a swirl of impeller import below can be eliminated to the single stage pump, improves the flow performance of liquid, reduces hydraulic losses, improves the efficiency of water pump. Show according to improving fore -and -after test report that the pump efficiency after the improvement on average improves two percentage points, has reached energy saving and emission reduction's purpose.
Description
Technical field
The utility model relates to pump structure field, particularly a kind of high efficiency single-stage pump.
Background technique
Single-stage pump is the simplest a kind of water pump structure, is also the maximum water pump type of consumption.Because its use amount is large especially, if so the efficiency that pump improves single-stage pump can play huge effect to energy saving, pump efficiency often improves one percentage point all can play sizable help to national energy-saving reduction of discharging.
Single-stage pump is mainly made up of component such as motor, the pump housing, impeller, pump covers, wherein affects the mainly pump housing impeller of pump efficiency.Import due to the pump housing is level, and the import of impeller is vertical, and liquid has the turning of 90 degree in the process being flowed into impeller inlet by pump housing import, particularly can form whirlpool in the below of impeller inlet, causes current not smooth, affects pump efficiency.
Model utility content
The purpose of this utility model solves the problem, and provides a kind of high efficiency single-stage pump, the basis of original pump body structure increases water guide cone, improve the efficiency of single-stage pump.
The technical solution of the utility model is as follows:
A kind of high efficiency single-stage pump, include the pump housing, motor, pump cover, in the pump housing, impeller is installed, pump shaft is connected with motor-driven, the impeller inlet place being positioned at the below of pump shaft is provided with water guide cone, the center line of water guide cone is identical with the center line of impeller, the height H of water guide cone upper end distance impeller inlet is equivalent to 1/5th of impeller inlet diameter D0, the diameter d of water guide cone lower end is equivalent to 1/3rd of impeller inlet diameter D0, water guide cone and the pump housing adopt R5 round-corner transition, and the tapering of water guide cone is 1:5.
The top of described water guide cone is hemisphere.
The utility model adopts single-stage pump of the present utility model can eliminate whirlpool below impeller inlet, improves the mobile performance of liquid, reduces hydraulic loss, improves the efficiency of water pump.Show according to the test report before and after improving, the pump efficiency after improvement on average improves two percentage points, reaches the object of energy-saving and emission-reduction.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and example, the utility model is elaborated.
Fig. 1 is structural representation of the present utility model.
Embodiment
