Description of drawings
Accompanying drawing is the utility model schematic block circuit diagram schematic diagram.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
Vaporation-type air cooling channel control system as shown in drawings, comprise the PLC controller, the input of PLC controller respectively with temperature sensor, humidity sensor, voltage transmitter, current transducer, pressure difference switch, conductivity meter, liquid-level switch is connected with remote signal, the output of PLC controller respectively with fan valve executor, blower motor, shower valve, spray valve, descaler and blowoff valve, water intaking valve, draining valve, the electrode pump, the humidification water circulating pump is connected with the blower fan heater, the PLC controller also is connected with touch-screen, operation push-button and alarm lamp, wherein the PLC controller adopts Schneider PLC high-performance integrated control platform system.
The control mode of this control system is divided into local manually control and remote signal control, and wherein local manually control is divided into following several form:
(1) control form of liquid-level switch controller: after blower fan was opened, entering water electromagnetic valve was opened, and began water inlet; When low-water level switch floated, the output of electrode pump was started working, when central water level switch floats, entering water electromagnetic valve is closed, and adopts the ball float moisturizing, when the high water level switch floats, the electrode pump quits work, and the output overflow was reported to the police when water tank began overflow, and opened drain solenoid valve;
(2) conductivity meter control form: by the detection to electrical conductivity of water, carry out draining and regulate, when electrical conductivity is higher than setting value, open drain solenoid valve, and the 30 seconds closed electrode pumps of delaying time, when electrical conductivity is lower than setting value, close drain solenoid valve, and open the electrode pump;
(3) flow switch control form: feedback electrode pump operation state, when the electrode pump turned round, pressure difference switch detected input, flow switch output;
(4) control form of spraying electromagnetic valve, spray solenoid valve: when devaporizer is opened, open first spraying electromagnetic valve, spray solenoid valve, and then open the electrode pump; When closing devaporizer, first closed electrode pump cuts out spraying electromagnetic valve, spray solenoid valve again, during the devaporizer compressor emergency shutdown, and the 30 seconds closed electrode pumps of delaying time.
Remote signal control can be carried out Remote control to equipment, and only need to system run signal to get final product as needing to start this moment, stops to get final product to system's stop signal.
Can show in real time the duty of vaporation-type air cooling channel and carry out associative operation by the touch-screen on this control system:
(1) the equipment operational factor shows: humidity, temperature, system power, system voltage when mainly showing the operation of vaporation-type air cooling channel device, and control on the spot the operation of vaporation-type air cooling channel device and stop;
(2) crawl operation: the independent on off control of each equipment is mainly used to commissioning device, jointly work such as starting humidification water circulating pump and blower fan heater, perhaps start separately the humidification water circulating pump or start separately the work of blower fan heater, such as will open descaler and blowoff valve the time, press the operation of descaler and blowoff valve and get final product again;
(3) system running state shows: the state of each equipment of display system and fault and control mode;
(4) system's running schematic diagram: the whole state that shows when vaporation-type air cooling channel device works;
(5) system equipment running status: the running status that shows each equipment.
But the parameters of operation push-button input equipment work wherein, such as humiture, electric current and voltage, flow value etc., alarm lamp is can glimmer when system breaks down, and hides during fault-free.
