Description
Technical field
The invention belongs to the control technology field of gas heater, especially relate to the gas heater control method of the many sources of the gas of a kind of automatic adaptation.
Background technology
Existing gas heater can only use single gas kind; When gas heater uses different source of the gas kind time-likes; The user need buy the gas heater of corresponding source of the gas again, or original gas heater is transformed, and these schemes all need the user to pay a large amount of costs.
Summary of the invention
In order to solve the deficiency that exists in the above-mentioned prior art, the present invention has designed the gas heater control method of the many sources of the gas of a kind of automatic adaptation, the user need not be changed or the modifying gas water heater can be suitable for multiple source of the gas equally.
Concrete scheme of the present invention is: the gas heater control method of the many sources of the gas of a kind of automatic adaptation comprises the steps: one) gather the data of inflow temperature, leaving water temperature, discharge through controller; Two) data are calculated by the formula of setting by controller; Three) regulate the input current of gas ratio valve and the rotating speed of speed-changing draught fan automatically according to calculated data, reach setting value up to the heat outputting load; Four) data of the input current of the input voltage of the input current of storage gas ratio valve this moment, speed-changing draught fan, speed-changing draught fan.This programme passes through to improve control method, thereby on the basis of not changing or improving gas heater, makes gas heater can be fit to multiple source of the gas, has saved user's cost greatly.
Above-mentioned gas heater is by the data parameters operation after storing.
The heat outputting of above-mentioned setting load is made as Φ, and specific heat of water is made as C, and leaving water temperature is made as T2, and inflow temperature is made as T1, and discharge is made as M, and the formula of described setting is Φ=C * (T2-T1) * M/3.6.
The water inlet end of above-mentioned gas heater is provided with water flow sensor, and water flow sensor is electrically connected with controller, sends the data of discharge to controller.
The water inlet end of above-mentioned gas heater is provided with temperature sensor, and temperature sensor is electrically connected with controller, sends the data of inflow temperature to controller.
The water side of above-mentioned gas heater is provided with temperature sensor, and temperature sensor is electrically connected with controller, sends out the data of coolant-temperature gage to controller.
Above-mentioned variable speed electric motors, particularly adopts the variable speed electric motors, particularly of strong drum structure.
Above-mentioned source of the gas comprises liquefied gas, butagas, 12T natural gas, 10T natural gas.
Main beneficial effect of the present invention is: need not change or transform gas heater; Just can make gas heater adapt to multiple source of the gas automatically through improving control method, it can both be adjusted to the duty an of the best automatically when the user uses different types of source of the gas.
Description of drawings
Fig. 1 is a workflow diagram of the present invention;
Fig. 2 is a circuit control logic connection layout of the present invention;
Fig. 3 is the graph of a relation of rotating speed of input current and the speed-changing draught fan of gas ratio valve of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is further specified.
As depicted in figs. 1 and 2, the gas heater control method of the many sources of the gas of a kind of automatic adaptation comprises the steps: one) gather the data of inflow temperature, leaving water temperature, discharge through controller; Two) data are calculated by the formula of setting by controller; Three) regulate the input current of gas ratio valve and the rotating speed of speed-changing draught fan automatically according to calculated data, reach setting value up to the heat outputting load; Four) data of the input current of the input voltage of the input current of storage gas ratio valve this moment, speed-changing draught fan, speed-changing draught fan.
Gas heater withdraws from and regulates or move by the data parameters maintenance of storing then, and later on also by this parameter operation.If change source of the gas again, can regulate again again to be suitable for new source of the gas.
The heat outputting load of wherein setting is made as Φ (kW), and specific heat of water is made as C=4.19 * 10
-3(MJ/ kg * K), leaving water temperature be made as T2 (℃), inflow temperature be made as T1 (℃), discharge is made as M (kg/h), the formula of setting is Φ=C * (T2-T1) * M/3.6.
The data M of discharge is sent to controller through the water flow sensor that is located at the gas heater water inlet end.
The data T1 of inflow temperature sends to controller through the temperature sensor that is located at the gas heater water inlet end.
The data T2 of leaving water temperature sends to controller through the temperature sensor that is located at the gas heater water side.
Multiple source of the gas comprises liquefied gas, butagas, 12T natural gas, 10T natural gas.
As shown in Figure 3, the rotating speed of speed-changing draught fan changes with the variation of the input current of gas ratio valve, finally adjusts to the combustion gas an of the best and the ratio of air.
For example: when the gas heater of a 20kW is not the nominal source of the gas when the source of the gas that uses; Its operating procedure is: opens burnt gas valve, inlet valve, goes out hot-water valve, and by start, by the adjusting pattern, the water heater operation of can starting point fighting at this moment; Temperature sensor, water flow sensor are gathered the data M of inflow temperature T1, leaving water temperature T2, discharge; And send data to controller, controller to data by formula Φ=C * (T2-T1) * M/3.6 calculate, regulate the input current of gas ratio valve and the rotating speed of speed-changing draught fan automatically according to calculated data; The value of loading when the heat outputting of gas heater reaches the factory setting value; During like 18kW, controller is storage each item quantity at that time automatically, comprising: the input current of the input current of gas ratio valve, the input voltage of speed-changing draught fan, speed-changing draught fan.After data-storing finished, gas heater can withdraw from the adjusting pattern automatically, and is in holding state.From then on begin, this water heater just can use this type of source of the gas, and moves and the ability operate as normal by the parameters of having stored.
