As shown in the figure, elevated tank suction booster described in the utility model has by power circuit, the full automatic controller that the contactor circuit of control power circuit break-make and the control circuit of control contactor connecting and disconnecting of the circuit are formed, wherein control circuit comprises the depressurization and rectification mu balanced circuit, pipeline whether there is water or not decision circuitry, water tank low water level decision circuitry, water tank high water level decision circuitry and relay circuit, above-mentioned three cover decision circuitry are by infrared-emitting diode Dk1, Dk2, Dk3, infrared receiving diode Dr1, Dr2, Dr3, comparison circuit, triode T1, T2, T3 and relay J 1, J2, J3 forms, relay circuit comprises main relay circuit and secondary relay circuit, and be provided with secondary relay J 5 in the secondary relay circuit, with the normally open contact J2k of the water tank low water level decision circuitry relay J 2 of the normally open contact J5k1 parallel connection of this pair relay J 5 and with the normally closed interlock J3k of the water tank high water level decision circuitry relay J 3 of this parallel connection contact circuit series connection, the normally closed interlock J1k of pipeline whether there is water or not decision circuitry relay J 1 is first on-off switch of main relay circuit, another normally open contact J5k2 of the secondary relay J 5 of secondary relay circuit is second on-off switch of main relay circuit, the normally open contact J4k of the main relay J4 of main relay circuit then is the on-off switch of contactor circuit, in addition, infrared-emitting diode Dk1 in pipeline whether there is water or not the decision circuitry and infrared receiving diode Dr1 are arranged in the water inlet probe 1 that is installed on the suction booster feed-water end, the ray shutter 4 that also is provided with ball float 3 and promotes in this water inlet probe 1 by ball float 3, infrared-emitting diode Dk2 in water tank low water level decision circuitry and the water tank high water level decision circuitry, Dk3 and infrared receiving diode Dr2, Dr3 is arranged on the tube wall of the transparent connecting tube 2 that is communicated with elevated tank, also is provided with ball float 5 in this transparent connecting tube 2.
As shown in the figure, present embodiment adopts step-down transformer BK, bridge rectifier D1～D4 and integrated package of pressure-stabilizing IC etc. to form the depressurization and rectification mu balanced circuit, as the DC electrical source and the D.C. regulated power supply of three cover decision circuitry and relay circuit; In three cover decision circuitry, be that main member is formed comparison circuit with triode T4, T5, T6 and operational amplifier A 1, A2, A3, wherein the operational amplifier A 1 in pipeline whether there is water or not the decision circuitry is opposite with the positive and negative electrode wiring of the operational amplifier A 2 in water tank low water level decision circuitry and the water tank high water level decision circuitry, A3, and the triode T4 of pipeline whether there is water or not decision circuitry is with also being provided with electrochemical capacitor C1 between the operational amplifier A 1, its effect is that time-delay is implemented in the action of the normally closed interlock J1k of relay J 1.
The elevated tank suction booster of the Automatic Control of said structure, when its pipeline whether there is water or not decision circuitry is judged as pipeline is anhydrous, relay J 1 conducting, normally closed interlock J1k opens, and the main relay circuit is not worked, not conducting of power circuit, suction booster does not start.When pipeline whether there is water or not decision circuitry and water tank low water level decision circuitry are made the judgement that pipeline has water and water tank low water level simultaneously, relay J 1 not conducting, relay J 2 conductings make normally open contact J2k closure, and cause secondary relay J 5 conductings and normally open contact J5k1, J5k2 closure, at this moment, because of two on-off switch complete closures of main relay circuit, main relay J4 is switched on, and makes contactor J conducting by often opening the closure of touching pass J4k, and then making the power circuit conducting, suction booster starts; When suction booster just started, the phenomenon of pressure drop can appear in intake pipe, and at this moment, electrochemical capacitor C1 will make normally closed interlock J1k continue to remain closed in set time.When cistern water level did not reach high water level above low water level, because of relay J 2 not conductings, normally open contact J2k had also opened, and secondary relay J 5 will continue conducting under the effect of self-locking contact J5k1, suction booster is kept on the go.When water tank high water level decision circuitry is made the high water level judgement, relay J 3 conductings, normally closed interlock J3k then opens, cause relay J 5 dead electricity, the main relay circuitry cuts, the suction booster shutdown this shows that this elevated tank suction booster can be realized fully automatic working under the control of full automatic controller.
