Description
Technical field
The present invention relates to the customized technologies of energy-saving water pump, more particularly to a kind of transformation of customized energy-efficient water pump
Method.
Background technique
Pump energy saving renovation technique mainly has 3 kinds at present:
1, according to live actual condition (flow, lift), existing Model of pump is selected.The flow of usual existing Model of pump
It does not often meet, can only be met the requirements by increasing or cutting impeller diameter with the flow of needs and lift with lift, and increase
Or the efficiency of cutting impeller diameter water pump can decrease.Or flow and lift are able to satisfy working condition requirement, but not with the highest of pump
Efficient point is overlapped.
2, by changing the revolving speed of water pump, such as frequency conversion, permanent-magnet speed governor and coupler speed control device, to change pump
Performance meets working condition requirement.Disadvantage: increased speed control device itself also consumes energy, and revolving speed changes the effect that can reduce pump itself simultaneously
Rate is not often also overlapped with the best efficiency point of pump.
3, increase regulating device, such as energy-saving control valve makes pump operation in high efficient district, reaches correction by changing Unit head
The purpose of operating condition.Disadvantage: regulating device itself also consumes energy, increases the security risk of apparatus system.
Summary of the invention
The purpose of the present invention is to provide a kind of remodeling methods of customized energy-efficient water pump, effectively solve above-mentioned skill
Art problem.
Effectively to solve above-mentioned technical problem, the technical solution adopted by the present invention is as follows:
A kind of remodeling method of customized energy-efficient water pump, method includes the following steps:
(1) water pump operation curve and parameter are set, definition flow is Q, head curve H, efficiency curve η:
(2) live actual motion flow-lift curve parameter value is defined as actual parameter point A；
(3) optimize various specific speed hydraulic models, establish outstanding database of hydraulic model, according to live actual operation parameters point A,
Outstanding hydraulic model, customized energy-efficient water pump or impeller is selected to design with the parameter point A of actual motion, flow-efficiency
The highest efficiency eta of curve Q- ηmaxIt is completely coincident with parameter point A.
Particularly, this method is further comprising the steps of:
Setting device curve H=KQ2, flow-lift curve and device curve H=KQ2Intersect at point A.

The inclined operating condition operation of water pump of having determined, meets design point and operating point actually required coincide, guarantee water pump best efficiency point and operating condition
Point is overlapped, while not increasing any extra means, securely and reliably.
The present invention is described in detail with reference to the accompanying drawing.
Detailed description of the invention
Fig. 1 is schematic diagram of the embodiment of the present invention.
Specific embodiment
Embodiment 1:
Scheme that this patent may be implemented only is illustrated with embodiment below, so not is intended to protect it to limit this patent
Scope, conjunction are first chatted bright.
With reference to Fig. 1, the first preferred embodiment of this patent, a kind of transformation side of customized energy-efficient water pump are shown
Method, method includes the following steps:
(1) water pump operation curve and parameter are set, definition flow is Q, head curve H, efficiency curve η:
(2) live actual motion flow-lift curve parameter value is defined as actual parameter point A；
