Abstract
The invention discloses the micro-processing technology of a controller for an electric heating steam generator. A probe is controlled in a real-time manner; the working state of the probe is correspondingly displayed by three light emitting diodes to protect an electric heating rod against damage; a low water level probe is additionally arranged; the probability of damaging an electric heating pipe is reduced due to the situation that two probes are hardly disabled at the same time; more importantly, the failure display of the two probes provides rapid prompt for maintenance; the double-pressure controller is used for controlling the pressure of a furnace so as to provide the reliable guarantee for the safety of the whole system; a water tank and a water pump are controlled synchronously to prevent the air from entering the water pump due to the water break of the water tank to result in the abnormal work and the damage of the water pump caused by heating.
Description
Technical field
The invention provides a kind of controller for electric heating steam generator, especially a kind of electrical heating of using microprocessing produces the controller for electric heating steam generator of steam.
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 safety and cuts down off-load,, safety occurs stopping up if cutting down, 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 detection, two pressure controller control, water tank and water pump that utilizes the electric conductivity of water to carry out the controller for electric heating steam generator of Synchronization Control.
The invention provides a kind of controller for electric heating steam generator, probe is controlled in real time, can be prevented the appearance that electrically heated rod damages, adopted 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.Microprocessor prevents to shake the appearance of seeing elephant 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 high 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 microprocessor 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 controller, high pressure controller, heating rod and water pump.Employing is controlled in real time 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.Microprocessor is handled the water probe signals, can prevent 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, in flue 1, be provided with heating rod 5 and three probes: two low-level probe and a high-level probe, three probes are electrically connected with 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 only in order to the explanation the present invention and and unrestricted technical scheme described in the invention; 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.
