C end (low-water level) of water level detector (U1) is by the light emitting diode three (V3) of connecting successively, relay two (K2), resistance ten (R10) ground connection afterwards.
Principle explanation
When low-water level, water level detector (U1) detects C end water (A, B 2 is anhydrous), high voltage is sent to C end, low-water level pilot lamp (i.e. light emitting diode) three (V3) is bright, now because A, B 2 is anhydrous, A, B 2 do not have voltage to input, so triode one (N1), triode two (N2) ground level do not have bias voltage, so the cut-off of triode one (N1), triode two (N2).Defeated 220V voltage is after the transformation, rectification of fuse (F1) transformer (T1) rectifier bridge (VD1), triode four (N4) conducting is made after resistance three (R3), voltage stabilizing diode four (D4), voltage stabilizing diode five (D5), thus make relay one (K1) obtain electric adhesive, its normal opened contact is connected, thus make contactor (KM1) obtain electric adhesive, contact, water pump brings into operation, and water pump operation pilot lamp four (V4) is bright simultaneously.
The base stage of triode four (N4) conducting then triode three (N3) is low level, so now triode three (N3) is in cut-off state.
When middle water level, water level detector detects B end water, and send high voltage to B end, V2 is bright for middle water level pilot lamp two, make triode two N2 produce bias voltage, triode two N2 conducting, but now triode three N3 is still cut-off state so B end provides high level.Such triode four N4 base stage remains high level, and triode four N4 keeps conducting state, and water pump continues to run.When water level rises to A point, water level detector detects A end water, and send high voltage to A end, V4 is bright for high water stage pilot lamp four, and triode one N1 base stage produces bias voltage, triode one N1 conducting.Now triode four N4 base voltage is by high step-down, and triode four N4 ends, relay one (K1) dead electricity, thus makes water pump dead electricity out of service, and water pump operation pilot lamp goes out.Triode four N4 ends, and the negative terminal voltage of pilot lamp four V4 is high level, so the base stage of triode four N4 is high level, and conducting state when now triode three N3 becomes water pump stopping from cut-off state when drawing water.
If now water level starts to decline, during lower than A point, triode one N1 base stage is low-voltage, and triode one N1 ends.But water level is still higher than B point, so B end still has high level to make triode two N2 keep conducting.Now because triode three N3 is conducting state, so triode four N4 base stage is still low level, triode four N4 ends, and relay one K1 is failure to actuate, and water pump does not run.When only having water level following lower than B point, equipment just can repeat above-mentioned work, automatically starts pumping for water pump.
When radiator leak or other situations cause water level decreasing too fast lower than low-water level C point time, relay two K2 dead electricity discharge, now its normally closed contact is on-state, hummer F1 can send alarm remind.Water pump also can start beginning moisturizing simultaneously, and more than moisturizing to C position, relay two K2 adhesive, its normally closed contact disconnects, and hummer (B1) stops alarm.
The effect of diode four D4, diode five D5 is the conduction voltage drop of offsetting triode two N2, triode three N3, and triode four N4 is normally ended.
As shown in Figure 2,3, then alternating current 220V electricity gives manual/auto selector switch (S1) by fuse two (F2).During manual/auto selector switch S1 selection auto state, S1-1 and S1-2 connects, now when sensor control circuit makes the adhesive of K1 relay, the normal opened contact K1-1 of its correspondence, K1-2 connects, and contact devices line bag (KM1) obtains electric adhesive, its corresponding contact.Because panel box air switch in this time (Q1) is conjunction state; overcurrent protection relay (FR1) is also adhesive in normal condition; such three-phase alternating current is by air switch Q1; overcurrent protection relay FR1, contact devices line bag KM1 contact makes water pump operation start moisturizing.We also can carry out Non-follow control with manual/auto selector switch S1, and S1-1 closes S1-3 and connects, and can make contactor KM1 adhesive if now press S2 ON button thus make water pump operation start moisturizing.Press S3 OFF button by the release of contact devices line bag KM1 dead electricity, water pump is out of service.
The invention is with low cost, economical and practical, installs simple, easily realizes the automatic control transformation of existing water tank.
