Abstract
The invention discloses a controller for an electric heating steam generator including a micro control plate. A control device is provided with a 4.5KG pressure controller and a 4KG pressure controller. A heating rod and three probes are arranged in a furnace, wherein the three probes are two low water probes and one high water probes, three probes are respectively electrically connected to the control device, a water pump is fixedly connected to a water tank, and the micro control plate controls the three probes, water level of the water tank, the water pump, the 4.5KG pressure controller, the 4KG pressure controller, and a heating electrothermal pipe in the furnace in real time. The three probes are arranged to detect the water level by using water conductivity. The double-pressure controllers are used to control the pressure of the internal furnace. The water tank and the water pump are synchronously controlled, so that the condition that the air enters the water pump caused by water cut-off of the water tank, thus the water pump can not work normally, even heats and damages is thus prevented.
Description
Technical field
The invention provides a kind of controller for electric heating steam generator, the electrical heating that especially a kind of electrical heating of using microprocessing produces steam produces the steam generator controller.
Background technology
At present, electrical heating generator is that heating rod obtains steam by electrical heating water.According to national standard, steam working pressure (SWP) is 0.4Mpa (promptly 4 kilograms), therefore, water level must be controlled, and selects three pin type water level controls, because the water that uses is hard water now, have many alkali matter, the alkali matter that can produce sclerosis in use for some time is incrustation scale, and incrustation scale can form a skim and cause the control failure around the probe of controller, thereby causes that electrically heated rod damages, present single the pressure controller that uses, if fault relies on the safety valve off-load, if stopping up appears in safety valve, security incident appears easily, cistern water level is not controlled, and causes water pump to advance air or heating easily, damages water pump.
Summary of the invention
The technical problem to be solved in the present invention is the defective that overcomes prior art, provides a kind of probe level of the electric conductivity of water of utilizing to detect, and two pressure controller controls, water tank and water pump carry out the controller for electric heating steam generator of Synchronization Control.
The invention provides a kind of controller for electric heating steam generator, comprise little processing controls plate, it is characterized in that: control device is provided with 4.5KG pressure controller and 4KG pressure controller, is provided with heating rod and three probes in flue: two low-level probe and a high-level probe, three probes are electrically connected with control device respectively, water pump is fixedlyed connected with water tank, and little processing controls plate is controlled in real time to three probes, cistern water level, water pump, 4.5KG pressure controller, 4KG pressure controller, heating electrothermal tubes in the flue;
Three probe control water levels;
Control device is provided with seven indicator lamps, 4.5KG pressure controller and 4KG pressure controller control flue pressure and cistern water level and water pump Synchronization Control.
To controlling in real time, can prevent the appearance that electrically heated rod damages to probe, adopt low-level probe of many increases, the situation that two probes lost efficacy simultaneously seldom occurs, so the probability that electrothermal tube damages greatly reduces; After having the more important thing is the monitoring in real time of two probes, prevented the probe fault to occur and the electrothermal tube damage, for maintenance provides prompting efficiently.Little processing controls plate prevents the appearance of jitter phenomenon effectively to water boiling Signal Processing.
The present invention has adopted following connected mode and operation principle: the cistern water level probe is connected control device; control device is provided with seven indicator lamps: the work of 4.5KG pressure controller; cistern water level work; heating work; adding water conservancy project does and three probe work; control device is provided with high pressure controller and low-pressure controller; in flue, be provided with heating rod and three probes: two low-level probe and a high-level probe; three probes are electrically connected with controller respectively; utilize little processing controls plate control; can effectively protect electric heating tube not to be damaged, water pump be fixedlyed connected with water tank.In the course of the work: owing to adopted Synchronization Control, reduce the appearance of water pump fault, two pressure controllers, it is 4KG that the low-pressure controller is provided with pressure, and it is 4.5KG that the high pressure controller is provided with pressure, and the high pressure controller is monitored, if high pressure controller indicator lamp work, illustrate that the low-pressure controller breaks down, at this moment stop to add water, could work after waiting to get rid of.
Because adopt above-mentioned technical scheme, the present invention has following beneficial effect:
Utilize the electric conductivity of water, three probe level monitorings are set, two pressure controller controls realize flue pressure is controlled, water tank and water pump are carried out Synchronization Control, can prevent owing to the water tank water pump that causes of cutting off the water supply advances air, thus cisco unity malfunction, even heating and damage water pump.

The specific embodiment
As shown in Figure 1, the invention provides a kind of controller for electric heating steam generator, comprise cistern water level, flue water level, control device, low-pressure device, high pressure device, heating rod and water pump.Employing is carried out control to probe, can prevent the appearance that electrically heated rod damages, and has adopted low-level probe of many increases, and the situation that two probes lost efficacy simultaneously seldom occurs, so the probability that electrothermal tube damages greatly reduces; After having the more important thing is the monitoring in real time of two probes, prevented electrothermal tube to damage and the demonstration of probe fault, for maintenance provides prompting efficiently.Little processing controls plate is handled the water pin signal of achieving one's aim easily, and can prevent the sealing boiling effectively and the fluctuation that causes.
Cistern water level probe 1 of the present invention connects control device 2, control device 2 is provided with three indicator lamps: operate as normal, the work of high pressure controller and cistern water level work, control device 2 is provided with high pressure controller 4 and low-pressure controller 3, is provided with heating rod 5 and three probes in flue 1: two low-level probe and a high-level probe, three probes are electrically connected with control device 2 respectively, and water pump 6 is fixedlyed connected with water tank 1.In the course of the work: owing to adopted two pressure controllers, it is 4KG that low-pressure controller 3 is provided with pressure, it is 4.5KG that high pressure controller 4 is provided with pressure, high pressure controller 4 is monitored, if high pressure controller 4 indicator lamp work, illustrate that low-pressure controller 3 breaks down, at this moment stop to add water, could work after waiting to get rid of.
It should be noted that at last: above embodiment is not to be limited to technical scheme described in the invention in order to explanation the present invention only; Therefore, although this specification has been described in detail the present invention with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the present invention; And all do not break away from the technical scheme and the improvement thereof of the spirit and scope of the present invention, and it all should be encompassed in the claim scope of the present invention.
