Description
Technical field
The present invention relates to electrical control equipment manufacturing technology field, especially a kind of boiler controlling device for miniature boiler.
Background technology
Current boiler controlling device is controlled the more of water level by float switch, by float switch, control water level and generally have two kinds of modes, a kind of is that float switch is with a large metal ball, when under water, buoyancy is large, can control two water levels, such as water has been expired, ball float rises because of buoyancy, the motion of drive ball valve, makes valve closing, stops into water; When water has lacked, ball float declines, and valve open, intakes again again, so circulation; This mode cost is low, but accuracy is not high.The second is electric wire formula float switch, and this device is connected with water pump by an elastic wire, allows to connect 220 volts of voltages, and a certain fixing point of counterweight or elastic wire, to the wire length between floating drum, determines the height of water level.This water level switch exists such problem: service life is relatively short, and majority directly connects 220 volts of voltages, has certain potential safety hazard.
Summary of the invention
The object of this invention is to provide a kind of boiler controlling device, it is not high that it can solve existing boiler controlling device control accuracy, has the problem of certain potential safety hazard.
In order to address the above problem, the technical solution used in the present invention is: this boiler controlling device, comprises control water pump, the primary circuit of air-introduced machine and air blast and secondary circuit; Also comprise water level controller; Described water level controller comprises central processing element, for described central processing element provides the power module of power supply; The input of described central processing element is connected with respectively high water level electrode, inferior high water level electrode, low water level electrode; The output of described central processing element is connected with respectively the first relay, the second relay and the 3rd relay; Inferior low water level electrode is connected with described high water level electrode by the first normally opened contact of described the second relay; The secondary circuit of the described water pump of the first normally-closed contact series connection access of described the first relay, the first normally-closed contact series connection described air-introduced machine of access of described the 3rd relay and the secondary circuit of air blast; The automatic branch road of the secondary circuit of the described water pump of the second normally opened contact series connection access of described the second relay.
In technique scheme, more specifically scheme can also be: the first normally opened contact of described the first relay and the too high warning lamp of water level are connected in series; The first normally opened contact of described the 3rd relay and the too low warning lamp of water level are connected in series; After the second normally opened contact parallel connection of the second normally opened contact of described the first relay and described the 3rd relay, be connected in series with audible alarm loop.
Owing to having adopted technique scheme, compared with prior art, the beneficial effect having is in the present invention: 1, owing to having adopted central processing element, so the water level control accuracy of boiler has improved.
2, power module is converted to low-voltage using high voltage and offers controller as operating voltage, so there is not the problem of potential safety hazard.
Accompanying drawing explanation
Fig. 1 is water level controller block diagram of the present invention.
Fig. 2 is principle block diagram of the present invention.
Fig. 3 is alarm principle block diagram of the present invention.
The specific embodiment
Below in conjunction with drawings and Examples, the invention will be further described:
Fig. 1, the boiler controlling device shown in Fig. 2 and Fig. 3, comprises control water pump, the primary circuit of air-introduced machine and air blast and secondary circuit; Water level controller 1 comprises central processing element 1-1, for central processing element 1-1 provides the power module 1-2 of power supply; The input of central processing element 1-1 is connected with respectively high water level electrode S5, inferior high water level electrode S4, low water level electrode S2; The output of central processing element 1-1 is connected with respectively the first relay LJ1, the second relay LJ2 and the 3rd relay LJ3; Inferior low water level electrode S3 is connected with time high water level electrode S4 by the first normally opened contact of the second relay LJ2; The secondary circuit of the first normally-closed contact series connection access water pump of the first relay LJ1, the first normally-closed contact series connection access air-introduced machine of the 3rd relay LJ3 and the secondary circuit of air blast; The automatic branch road of the secondary circuit of the second normally opened contact series connection access water pump of the second relay LJ2.High water level electrode S5, inferior high water level electrode S4, low water level electrode S2, the common port S1 of inferior low water level electrode S3 is connected with the earth terminal COM of central processing element 1-1.The present invention carrys out the variation of level monitoring by configured electrodes, the center line of Boiler Furnace cylinder of take is zero-bit, and four corresponding water levels of electrode are :-80 centimetres, and-25 centimetres ,+25 centimetres ,+70 centimetres.When boiler water level is during lower than-25 centimetres, central processing element 1-1 makes the coil of the second relay LJ2 obtain electric adhesive, closed water pump control loop, the water pump pump water connected of the second normally opened contact.When water level arrives+25 centimetres, central processing element 1-1 disconnects the coil losing electricity of the second relay LJ2, and the second normally opened contact disconnects, water pump control loop dead electricity, and water pump stops pump water.This device is provided with automatically, and MTS, when automatic control is malfunctioning, switches to manual position by change-over switch, can manual start and stop water pump by start-stop button.
When boiler water level is during lower than-80 centimetres; the coil adhesive of the 3rd relay LJ3; its first normally opened contact is closed, and the too low warning lamp 1WD of water level sends light alarm, and the second normally opened contact of the 3rd relay LJ3 is closed simultaneously; make the audible alarm loop energising warning of sounding; meanwhile, the first normally-closed contact of the 3rd relay LJ3 disconnects, and makes the secondary circuit power-off of air-introduced machine and air blast; thereby air-introduced machine and air blast are stopped operating, reach the protection to boiler drum.When boiler water level high during to+70 centimetres, the coil of the first relay LJ1 obtains electric adhesive, its first normally opened contact and the second normally opened contact are closed, send sound and light alarm, and are disconnected and made water pump secondary circuit dead electricity that water pump is stopped operating by its first normally-closed contact.
