Description
Technical field
The present invention relates to industrial technical field more particularly to a kind of gas cooker thermal efficiency detection water flow test pots.
Background technology
Existing burner national standard includes GB30720-2014《Household fires kitchen range energy efficiency market and efficiency grade》, use
In the fuel efficiency efficiency and efficiency grade of evaluation burner.Burner thermal efficiency test method usually detects combustion gas by test pans and disappears at present
Relationship between the increased enthalpy of water in the calorie value that consumption can theoretically generate, with experiment pot is obtained indirectly by calculating
The gas cooker thermal efficiency.
However, when existing test pans carry out the thermal efficiency detection of household gas utensils, by artificial stirring test pot or
The self- poking arrangement of design specialized.Experiment process is needed according to actual measurement thermic load selection upper limit pot and lower limit pot；Distinguish later
It is packed into the water of a nominal-mass in upper limit pot；It needs that the water of upper limit pot and lower limit pot is heated to end from initial temperature respectively later
Temperature.Above-mentioned upper limit pot and lower limit pot at least Repeat-heating twice, that is, usually require 4 pots of water of heating.In the process, when adding
After the complete one pot of water of heat, needs to change another pot of water and heat again, it is therefore desirable to frequently replace test pans, and weigh the water of addition
Amount, detection work step is cumbersome, the amount of labour is big and is easy error.Every pot of water is required for being heated to final temperature from initial temperature, when water heats
Between it is long, the test period is long, reduces detection efficiency.
Invention content
Need to frequently replace that test pans, test period are long, and detection efficiency is low when thermal efficiency detection in the prior art to overcome
The problem of, an embodiment of the present invention provides a kind of gas cooker thermal efficiency detection water flow test pots.
A kind of detection of the gas cooker thermal efficiency water flow test pot, including pot body further include：Water stream channel, the flow are logical
Road include the water inlet being formed in pot body, water outlet and set between water inlet and water outlet and with water inlet and water outlet
The heat transfer pipe that the detour that mouth is connected extends.
The embodiment of the present invention in test pans pot body by being arranged water stream channel, and when carrying out thermal efficiency detection, experiment is used
Water is flowed into from water inlet, is flowed out by the water stream channel in pot body and from water outlet, so that test water is burnt with gas cooker and is fired
Heat exchanger carrier is used as by pot body between the high-temperature flue gas generated when gas and realizes heat exchange indirectly, makes flow from experiment pot
Water inlet flow into from the water outlet of experiment pot flow out during realize water temperature raising.The gas cooker thermal efficiency detects
When, it can be increased by the calorific value that amount of consumed gas as defined in detection theoretically generates and the inflow of experiment pot and the water of outflow
Relationship obtains the gas cooker thermal efficiency indirectly by calculating between enthalpy, and the detection test period is short, and detection efficiency is high, and detection is continuous
It is free of discontinuities, without frequently replacing test pans.In addition, the stabilization in the temperature field in the temperature field and the bottom of a pan of flow can be effective in test pans
Terminated from on-test and experiment when the thermal efficiency being avoided to detect during the wild effect that persistently changes of temperature field, improve inspection
The overall stability of examining system, it is advantageously ensured that the reliability of test result.
Flow type test pans using the present invention, when combustion system and water flow control system reach stable, in test pans
Water outlet will have continual and steady hot water outflow, after finishing a thermal efficiency test, need not add water that can carry out at once next
Secondary experiment can make the detection of the gas cooker thermal efficiency realize repeatedly uninterrupted progress, save non-cutting time and save gas consumption.Separately
Outside, since water outlet flow and water temperature are relative constant, can start at any time or termination test, and can root
The test required time is arbitrarily adjusted according to actual conditions so that test operation becomes simple light.Use the survey of the test pans
Test system introduces automation control and real-time monitoring and control etc., it can be achieved that detecting certainly when fuel gas combustion system and water flow control system
Dynamicization and it can realize the multiple stations of one man operation.It, can be real-time before reaching stable combustion testing after gas cooker is burnt 15 minutes
Automated or manually adjusted the state that system reaches test requirements document.
