3Between become open circuit.When water level is lower than the lower position in the tower, when promptly being lower than the bottom surface of the ball 6 that is filled with water, if water on for some reason can not pump, switch A and switch B then can not returns, water pump 13 is in the dangerous fault state, therefore water pump 13 in this state, motor and circuit can produce a large amount of heat, and the thermorelay 18 on its input phase line disconnects, and makes entire circuit all become open circuit; If thermorelay 18 heats are reduced to conventional state and are automatically reset, because of switch A and the switch B ball 6 lower limit water level potential energy locking that is filled with water, entire circuit all can't form path, failure warning lamp 19 can send barrier for some reason and alarm signal that circuit is locked with light, at this moment, have only after pending fault eliminates, pressing can the release operation behind the hand push button E.
Referring to accompanying drawing, specific operation are as follows:
(1) ball 6 that is filled with water in the support in the mechanical linkage 1 is to tie up to lateral part at the bottom of the front end of water storage case 4.The ball 6 that is filled with water is immersed in the interior water of water tower.When water level is lower than the lower position in the tower, when promptly being lower than the bottom surface of the ball 6 that is filled with water, the gravitational potential energy of ball 6 owing to be filled with water, ball 6 tenesmus that are filled with water affect water storage case 43 upsets downwards around the shaft on the horizontal guide 2, equilibrium block 8 disequilibriums of horizontal guide 2 the other ends move upward and drive vertical guide rod 9 and move upward, vertical guide rod 9 tops head on the rear end tread of " V " shape key plate 10, " V " shape key plate 10 rotates along the rotating shaft of key plate, the front end tread flexibility of " V " shape key plate 10 is pressed on the switch A and switch B of two combination double circuit double combination type sensitive switches 11, make switch A and switch B action, connect startup winding 16 circuit in the A.C. contactor 15, A.C. contactor 15 starts, and this action also can be finished by pressing hand push button E.So the water pump 13 that is connected on the output circuit enters working state, trouble free service tutorial light 12 is bright.
(2) when water pump 13 is in resource of water supply 14 pump water input water tower, wherein some water is the water filling conduit 5 injection water storage cases 4 in conduit pipe outlet 21, release to water tower from water storage case 4 bottom spilled water holes 7 simultaneously again, the ball 6 that is filled with water that hangs raises with water level in the tower and loses the potential energy effect, again because of inflows in the water storage case 4 greater than the amount of releasing, fill with the potential energy that water produced of water storage case 4 second through 2-3, keep 4 times inclined to one side situation of water storage case, thereby the maintenance power circuit is a path always.
(3) water level rises to water level in tower, when being water storage case 4 upper surfaces, the water in the water storage case 4 loses potential energy, influenced by the effect of horizontal guide 2 the other end equilibrium blocks 8 and the return elastic force of switch A, switch B, switch A, switch B move again power-circuit breaking, stop pump water.
(4) if work midway; or water pump fault or centrifugal pump gas leakage or water intake obstruction or resource of water supply 14 anhydrous supplies; water pump 13 is pump water not; water in the water storage case 4 releases from spilled water hole 7 in second at 2-3 and forms sylphon and lose potential energy; influenced by the effect of horizontal guide 2 the other end equilibrium blocks 8 and the return elastic force of switch A, switch B; switch A, switch B move again power-circuit breaking, and water pump 13 quits work, and realize the best protection measure of water pump 13.
