Description
Technical field
The utility model relates to a kind of external water pump systems of gas-heating water heater.
Background technique
Existing gas-heating water heater system provided causes pipeline crooked position more often because pipeline installation is unreasonable,
So that system resistance is excessive, the water pump overload operation of gas-heating water heater is caused, gas-heating water heater is caused frequently to surpass
Temperature is flame-out, influences heating effect.At this moment since pipeline has been completed, the pipeline of especially some engineerings is the side using concealed installation
Formula, if it is desired to which changing pipeline will be a very great engineering.And after running one period, due to system pipeline
Fouling can further increase system resistance, and gas-heating water heater load is caused to be further aggravated, acceleration equipment aging.
The prior art is mostly in addition individually to increase water pump in heating terminal, increases the water route flow of system, guarantees heating effect
Fruit.And increase water pump and just need to increase corresponding control system, it so will increase equipment cost and operating cost, more than two
It will appear the nonsynchronous situation of operation between a water pump, reduce the operational efficiency and safety of gas-heating water heater water pump
Energy.
Utility model content
The utility model proposes a kind of external water pump system of gas-heating water heater, solve above-mentioned in the prior art ask
Topic.
The technical solution of the utility model is achieved in that
A kind of external water pump system of gas-heating water heater, including heat exchanger arranged in the box body, heat exchanger with
Radiator connection, radiator are connect with outer water pump, and outer water pump is connect with built-in water pump, and built-in water pump and heat exchanger connect
It connects；
It is provided with cpu controller on cabinet, is provided with flow sensor on outer water pump；
Cpu controller is electrically connected with built-in water pump；
Cpu controller is electrically connected with outer water pump；
Cpu controller is electrically connected with flow sensor.
Preferably, outer water pump is variable frequency pump.
The beneficial effects of the utility model are:
It can be chosen whether to open outer water pump according to the actual demand of user, increase the dynamic role of equipment, effectively improve and adopt
Warm effect reduces expense and pays, high degree of automation, and overall utility is strong.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, before not making the creative labor property
It puts, is also possible to obtain other drawings based on these drawings.
Fig. 1 is a kind of structural schematic diagram of the external water pump system of gas-heating water heater of the utility model；
The step of Fig. 2 is the utility model gas-heating water heater external water pump system control method implements figure.
In figure:
1, cpu controller；2, flow sensor；3, cabinet；4, interior heat exchanger；5, radiator；6, outer water pump；7,
Built-in water pump.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts
Every other embodiment obtained, fall within the protection scope of the utility model.
As shown in fig. 1, the external water pump system of a kind of gas-heating water heater described in the utility model, including it is set to case
Heat exchanger 4 in body 3, heat exchanger 4 are connect with radiator 5, and radiator 5 is connect with outer water pump 6, outer water pump 6 with it is interior
The connection of water pump 7 is set, built-in water pump 7 is connect with heat exchanger 4；
After gas-heating water heater starting, built-in water pump 7 starts, and makes the water in system from heat exchanger 4s, successively
Radiator 5, outer water pump 6, built-in water pump 7 are flowed through, heat exchanger 4 is returned to, completes a circulation.
It is provided with cpu controller 1 on cabinet 3, is provided with flow sensor 2 on outer water pump 6；
Flow sensor 2 is for dynamically obtaining water route flow value L；
Cpu controller 1 is built-in to control program, for controlling the operation of entire gas-heating water heater system provided；
Cpu controller 1 is electrically connected with built-in water pump 7；
Cpu controller 1 is electrically connected with outer water pump 6；
Cpu controller 1 is electrically connected with flow sensor 2.
Preferably, outer water pump 6 is variable frequency pump.
Variable frequency pump is selected, the output flow of outer water pump 6 can be adjusted, arbitrarily to reach the design requirement of system.
Such as Fig. 2, the control method of the external water pump system of gas-heating water heater, comprising the following steps:
S1:CPU controller 1 dynamically obtains the water route flow value L of system by flow sensor 2；
S2: when water route flow value L is less than default minimum starting flow value Lq, cpu controller 1 issues frequency conversion instruction, control
It makes outer water pump 6 to start, and is gradually increased output flow, until being equal to water route flow value L presets external water pump operation flow
Value Ly；
S3: when water route flow value L, which is greater than, presets external water pump operation flow value Ly, cpu controller 1 controls outer water pump
6 is out of service.
Using frequency control, system operation can be made more steady.
The external water pump system of gas-heating water heater described in the utility model and control method, can be according to the reality of user
Demand chooses whether to open outer water pump, increases the dynamic role of equipment, effectively improves heating effect, reduces expense expenditure, automatically
Change degree is high, and overall utility is strong.
