The input start end of bavin pump；
In Fig. 1 and Fig. 2,
Automatic/manual switch SA1(SA1-1, SA1-2, SA1-3) it is currently manual mode, it can be switched to certainly after pressing SA1
Dynamic state；
Bavin/electrical switch SA2(SA2-1, SA2-2) state currently is pumped for bavin, electric pump state is switched to after pressing；
Electric machine controller U1 uses the WJB+300/5ZT Δ intelligent protection monitor of Shuan Hua Electrical Appliances Co., Ltd；
Each on-off action:
SB1-1 is manually controlled under state, shutdown switch；
SB1-2, under automatic control state, shutdown switch；
SB2 is manually controlled under state, is started switch；
SB5, another shutdown switch can be placed in the place except scene, such as monitoring room；
SB3, force start switch, simulated fire occur；
SB4, electric pump starting failure reset switch；
When automatic/manual switch SA1 is switched to automated location, pump operation is opened automatically, is generally made when being switched to manual position
Overhaul of the equipments is used；
Bavin/electrical switch SA2 can an optional electric pump or bavin pump be used as main pump, main pump starting failure, standby pump puts into operation immediately,
To guarantee the reliability of spray system；
Below using electric pump as main pump, bavin pump is standby pump, illustrates the working principle for controlling route；
It is closed master switch QF first, bavin/electrical switch SA2 selects electric pump position, i.e. closure SA2-1, is closed SA2-2, simultaneously
Automatic/manual switch SA1 is switched to automated location, i.e. closure SA1-1, disconnects SA1-2, closure SA1-3；-> relay
KA1 coil obtains electric -> relay KA1 normally opened contact KA1-1 closure, while another normally opened contact KA1-2 is closed, when fire occurs
When, spray head is opened, and pressure switch P movement closure (opening pump signal), relay 1KA coil obtains electric -> relay 1KA normally opened contact
1KA-1 closure -> relay KA3 coil obtain it is electric, and by closure KA3-2 realize relay KA3 it is self-locking -> relay KA3 is normally opened
Contact KA3-1 closure -> contactor KM3 coil obtains electric -> contactor KM3 normally opened contact KM3-1 closure -> contactor KM1 coil and obtains
Electricity -> contactor KM1 normally opened contact KM1-1 closure and self-locking KM1 coil -> contactor KM1 main contacts KM1-0, contactor KM3 master
Contact KM3-0 closure -> motor M obtains electric, is being monitored by star connection starting -> electric machine controller U1 by Current Transmit
Start timing in route after starting current, the delayed contact ST inside electric machine controller U1 was delayed afterwards at 8~10 seconds (can set)
Contact ST closure -> relay KA0 coil obtain it is electric, closure KA0-3 it is self-locking -> relay KA0 normally-closed contact KA0-1 disconnection -> contact
Device KM3 coil losing electricity, while relay KA0 normally opened contact KA0-2 is closed, contactor KM2 coil obtains electric, contactor KM2, KM3
Between disconnected by KM2-1, KM3-2 interlocking -> contactor KM3 main contacts KM3-0, contactor KM2 main contacts KM2-0 closure, electricity
Machine M is transformed into delta connection operating, motor star triangle start completion by star connection；Then electric pump passes through the water in pond
Pipeline is provided to pipe network, entire spray system work；
When electric pump is run, contactor KM2 normally opened contact KM2-2 closure, buzzer HY2 alarm, so that monitoring room personnel learn hair
Fire is sent, and electric pump starts automatically；
Under automatic control state, if electric pump starting failure, the principle for moving on to bavin pump startup automatically are as follows:
Electric motor starting, if the conversion of star triangle is unsuccessful, contactor KM2, KM3 are unable to normal conversion, then being in fact exactly detection electricity
After machine M starts 10 seconds, contactor KM2 whether electric conversion actuation；
After pressure switch P closure, since relay 1KA normally opened contact 1KA-1 is closed, relay KA3 coil obtains electric, relay
The normally opened contact KA3-2 of KA3 is also closure；SA1-3 is closure under auto state, and timer KT obtains electric timing；
Timer KT timing in settable 1 minute, after motor M starting, if starting successfully KM2-3 normally-closed contact disconnection, timer KT
Power loss exits work；If if motor star triangle start is also unsuccessful after one minute, energization delay relay normally opened contact KT-1
Closure -> relay KA2 coil obtain it is electric -> relay KA2 normally opened contact KA2-3 closure and it is self-locking, normally-closed contact KA2-2 disconnect ->
Relay KA1 coil losing electricity -> relay KA1 normally opened contact K1-2 disconnection -> contactor KM1, KM3 coil losing electricity -> contactor
KM1, KM3 main contacts KM1-0, KM3-0 are disconnected, and motor M stops starting, while starting unsuccessfully indicator light HY4 and lighting, relay KA
Normally-closed contact KA2-4 is disconnected, as soon as sending out a break impulse gives bavin pump startup input terminal, the automatic starting operation of bavin pump；
When bavin pump operation, bavin pump operation exports switch CK2 closure, and relay 2KA coil obtains electric, relay 2KA normally opened contact
2KA-1 closure, buzzer HY3 alarm, so that monitoring room personnel learn transmission fire, and bavin pump starts automatically；
When bavin pump is main pump, when fire, pressure switch P closure, relay 1KA coil obtains electric, and normally-closed contact 1KA-2 is disconnected,
A break impulse can be sent out and give bavin pump startup input terminal, to start bavin pump；
When breaking down, bavin failure of pump exports switch CK1 and is closed bavin pump, relay KC coil obtain it is electric so that normally opened contact KC-1
Closure, in the case where master switch QF closure, relay KA1 coil can obtain electric, then start the starting of electric pump, and above-mentioned
Electric pump start-up course is similar, repeats no more.
It should be noted last that the above specific embodiment is only used to illustrate the technical scheme of the present invention and not to limit it,
Although being described the invention in detail referring to example, those skilled in the art should understand that, it can be to the present invention
Technical solution be modified or replaced equivalently, without departing from the spirit and scope of the technical solution of the present invention, should all cover
In the scope of the claims of the present invention.
