Abstract
The invention discloses a water level control device, and relates to the technical field of electrical control. The water level control device comprises a box door connected with a box body in a hinged mode. A change-over switch, a stop button, a start button, a red signal lamp, a green signal lamp and a water level controller are arranged on the box door respectively. A contactor, a thermal relay and a relay are arranged in the box body respectively. The change-over switch, the water level controller and the relay are connected in series to form a starting/stopping signal circuit. The change-over switch, the stop button, the start button, the contactor and the thermal relay are connected in series to form a manual circuit. The start button and the contactor are connected in parallel to form a self-protection circuit. The change-over switch, the relay, the contactor and the thermal relay are connected in series to form an automatic circuit. The scheme of the water level control device replaces an existing water level control scheme.
Description
Technical field
The present invention relates to electrical control equipment manufacturing technology field, especially a kind of water-level control apparatus of controlling for water level.
Background technology
Current water level controller 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 degree of 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 point of fixity of balance bob or elastic wire, to the wire length between floating drum, determines the height of water level.This water level switch exists such problem: serviceable life is relatively short, and majority directly connects 220 volts of voltages, has certain potential safety hazard; These two kinds of control modes respectively have relative merits.
Summary of the invention
The object of this invention is to provide a kind of water-level control apparatus, it can become the replacement scheme of existing water level control program.
In order to address the above problem, the technical solution used in the present invention is: this water-level control apparatus, comprises the chamber door hinged with casing; On described chamber door, be separately installed with switch, stop button, start button, red eye, greensignal light and water level controller; In described casing, be separately installed with contactor, electrothermal relay and relay; Described switch, water level controller and relay series connection form start/stop signal circuit; Described switch, stop button, start button, contactor and electrothermal relay series connection form manual circuit; Described start button and the described contactor holding circuit that forms in parallel; Described switch, relay, contactor and electrothermal relay series connection form automatic circuit.
In technique scheme, more specifically scheme can also be: described contactor and red eye series connection form enabling signal indicating circuit; Described contactor and greensignal light series connection form stop signal indicating circuit.
Owing to having adopted technique scheme, the present invention compared with prior art, the beneficial effect having is: in some small business, because water consumption is not very large, do not need very large water tower can meet daily water consumption demand, so control does not need very accurate yet for water level, operation circuit of the present invention is simple, and the place that is just in time applicable to the very complicated control program of needs is not used.
Accompanying drawing explanation
Fig. 1 is front elevational schematic of the present invention.
Fig. 2 is electrical principle schematic diagram of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described:
Water-level control apparatus shown in Fig. 1 and Fig. 2, comprises the chamber door hinged with casing; On chamber door, be separately installed with switch SA, stop button SB1, start button SB2, red eye HR, greensignal light HG and water level controller KG; In casing, be separately installed with contactor KM, electrothermal relay KR and relay K A; Switch SA, water level controller KG and relay K A series connection form start/stop signal circuit; Switch SA, stop button SB1, start button SB2, contactor KM and electrothermal relay KR series connection form manual circuit; Start button SB2 and the contactor KM holding circuit that forms in parallel; Switch SA, relay K A, contactor KM and electrothermal relay KR series connection form automatic circuit.Contactor KM and red eye HR series connection form enabling signal indicating circuit; Contactor KM and greensignal light HG series connection form stop signal indicating circuit.
Electrothermal relay KR is connected with pump motor by cable.When work, when using automatic catch to control, switch SA is got to automatic catch, and when water level is during lower than setting value, signal of water level controller KG output is to the coil of relay K A, the coil adhesive action of relay K A, switch SA, relay K A, the automatic circuit action that contactor KM and electrothermal relay KR series connection form, contactor KM controls pump operation, and water pump starts to draw water; When water level reaches setting value, water level controller KG disconnects output terminal, and relay K A dead electricity is cut off automatic circuit, and contactor KM dead electricity, stops pumping water pump.When water pump entry into service, the enabling signal indicating circuit that contactor KM and red eye HR series connection forms is connected, and red eye HR lights, and shows that water pump starts working; After water pump shuts down, the stop signal indicating circuit that contactor KM and greensignal light HG series connection form is connected, and greensignal light HG lights, and shows that water pump quits work.When automatic circuit breaks down or overhaul, switch SA can be got to manual gear, by start button SB2, start water pump, or by the stop button SB1 water pump that stops.
