Specific embodiment
Referring to Fig. 1, the utility model provides a kind of electrolyte conveying pump refrigerating device, has the water being set on ground
Case 1, and height of the water tank 1 apart from ground be at 10 meters or more, and the volume of water tank 1 is one cubic metre；The connection water inlet of water tank 1
Pipe 2 and water-supply-pipe 3, are equipped with control valve A4 on water inlet pipe 2, equipped with opening for monitoring the Floating Ball Liquid Level of its liquid level in water tank 1
Close 5；Several branch pipes 6 are equipped on water-supply-pipe 3, every branch pipe 6 is correspondingly connected with 7 upper bearing (metal) cooling jacket 8 of a delivery pump
The cooling water outlet 10 of cooling water inlet 9, bearing cooling jacket 8 connects electrolysis system, and control valve is housed on every branch pipe 6
B11。
The height apart from ground is arranged at 10 meters or more, to ensure that water tank is cooling to bearing in water tank 1 in the present embodiment
The hydraulic pressure of the given cooling water in the cooling water inlet 9 of collet 8 is greater than the pressure that delivery pump 7 seals leakage, to prevent delivery pump 7
It is not tight in operation Shi Yinqi sleeve sealing and cause electrolyte return string into water-supply-pipe 3.
Control valve A4 described in the present embodiment and control valve B11 are all made of solenoid valve；The communication of floating-ball level switch 5 connects
The On-off signal port of PLC controller 12 is connect, floating-ball level switch 5 ensures water for the water level in real-time monitoring water tank 1
Water level in case 1 maintains certain setting value, and when the water level in water tank 1 exceeds the setting value, floating-ball level switch 5 can at once
Movement, the on-off model that PLC controller 12 gives according to floating-ball level switch 5, output switching value instruction, so that control valve A4
It closes, water inlet pipe 2 stops to 1 moisturizing of water tank.
In the side of every delivery pump 7 starting box 13 that its opens/stops configured with control in the present embodiment, in starting box 13
Equipped with main circuit power supply and secondary control loop, referring to fig. 2；Having air switch QS, contact are sequentially connected in series on main circuit power supply
The main contacts KM1-1 and thermoelectric protector FR of device KM1, secondary control loop take electricity from main circuit power supply, and in secondary control
The normally-closed contact FR1 of thermoelectric protector FR, the line of stop button SB1, start button SB2 and contactor KM1 are in series on circuit
Packet, the normally opened auxiliary contact KM1-2 of one of contactor KM1 are connected in parallel on the both ends of start button SB2, contactor KM1 another
Normally opened auxiliary contact KM1-3(be not marked in figure 2) connection PLC controller 12 On-off signal port, thus PLC controller
12 according to the energized state of contactor KM1, i.e., can be realized according to the on-off model that normally opened auxiliary contact KM1-3 gives to control
The switch state of valve A4 and control valve B11 carry out real-time control.
In actual operation, it when needing to start delivery pump 7, directly presses on starting box 13 corresponding to the delivery pump
Start button SB2, at this time the line Bao get electricity of contactor KM1, main contacts KM1-1 and two normally opened auxiliary contact KM1-2, KM1-
3 are closed, then the stator coil of delivery pump 7 obtains electric and makes the starting operation of delivery pump 7, simultaneously, normally opened auxiliary contact
KM1-3 gives an on-off model (being equivalent to high level) to PLC controller 12, and PLC controller 12 exports switching value instruction,
First control control valve B11 is opened, then controls control valve A4 unlatching, from the moisturizing into water tank 1 of water inlet pipe 2, even if burst cut off the water or
The case where water-supply-pipe 3 ruptures, the water in water tank 1 can also at least maintain delivery pump 7 that it is more than hour to run one, and this period is convenient for
Service personnel carries out termination of pumping operation in time；
When needing termination of pumping, the stop button SB1 on starting box 13 corresponding to the delivery pump is directly pressed, at this time because connecing
The line packet power loss of tentaculum KM1 then conveys so that its main contacts KM1-1 and two normally opened auxiliary contact KM1-2, KM1-3 are disconnected
It is out of service to pump 7, and normally opened auxiliary contact KM1-3 gives an on-off model to PLC controller 12 and (is equivalent to low electricity
It is flat), PLC controller 12 exports control instruction, first controls control valve B11 and closes, then controls control valve A4 closing.
