D. after suction was finished, valve-off 9 was closed the suction switch, takes off suction hose, covered water pump orifice 6 lids;
E. open valve 5.
3, the ratio Hybrid Heating of deicing liquid, water and ratio are sprayed
The ratio mixed process of deicing liquid, water is: select the deicing liquid on the guidance panel and the blending ratio of water as required, this scaling signal is transferred to PLC, and PLC gives initial value signal according to the signal of input to proportion magnetic valve.In the sprinkling process, be located at deicer pump 34, the flow counter 27 in water pump 8 exits, flow counter 12 feeds back to PLC to the flow signal that collects in real time, PLC compares flow meter signal and preset value, when flow meter signal is lower than preset value, PLC increases output to proportion magnetic valve automatically, when flow meter signal is higher than preset value, PLC reduces output to proportion magnetic valve automatically, thereby revise the opening degree of proportion magnetic valve, control enters the hydraulic fluid flow rate of HM Hydraulic Motor, so just change the deicer pump motor, the rotating speed of pump motor, the flow velocity of deicing liquid and water can increase along with the rotating speed of motor and increase, reduce and reduce.Adjustment deicing through a plurality of cycles is stabilized on the default ratio than regular meeting repeatedly, thereby reaches the purpose with accurate ratio deicing.
The mixed deicing liquid of ratio enters boiler 22 and heats, and the heating controller of boiler 22 can carry out the big and small fire heating automatically according to detected inlet mixeding liquid temperature, thereby guarantees that the mixeding liquid temperature of boiler 22 outlets reaches the spray temperature of setting.
In deicing heating, sprinkling process, close high-altitude spray gun 17 or ground spray gun 18 once in a while, PLC detects and can open return flow solenoid valve 29, water return flow solenoid valve 10 immediately after spray gun does not have flow signal, deicing liquid and water are back in separately the deicing liquid case 2 and water tank 3, guarantee that pipeline does not build the pressure, and PLC can control boiler 22 and was automatically brought to little fiery state this moment.After spray gun high-altitude 17 or ground spray gun 18 are opened, after PLC detects the signal of gun traffic, closing volume electromagnetic valve 29, water return flow solenoid valve 10 immediately, boiler 22 controllers can carry out the big and small fire heating automatically according to the temperature of inlet.Proportioning concentration after the heating is from spray gun high-altitude 17 or ground spray gun 18 ejection.
When close that the deicing ratio is sprayed and boiler after, PLC can control deicer pump, water pump time-delay 2min shuts down, this moment, return flow solenoid valve EV1, EV2 can open, and took away in the boiler furnace behind the waste heat, deicer pump, water pump can auto-stops.
In addition, be fixed with four electric heaters in the water tank side, the thermocouple well dispersed placement of electric heater is in water tank.When not adopting the boiler heating, can pass through external 380V power supply, adopt electric heater that water is heated to 30 ℃.This moment, water pump was need not use work, only needed simultaneously or open separately 1,2,3 on the electro heat control capsule, 4# electro heat switch, and the water in the water tank can be heated to design temperature automatically, and each temperature booster all works alone, and temperature also is independently to set.Also can directly be heated to design temperature as required, and not need to carry out in advance electro heat with boiler.
4, deicer pump assembly
Deicing liquid suction, heating and sprinkling are all finished by a diaphragm pump.This pump passes through the coupler direct drive by HM Hydraulic Motor.Deicer pump is provided with deicing liquid case sky, pipeline overpressure protection, and deicer pump can not start or protect shutdown this moment.
5, water pump complement
The suction of water, heating and sprinkling are all finished by a diaphragm pump.This water pump passes through the coupler direct drive by HM Hydraulic Motor.This water pump is provided with water tank sky, pipeline overpressure protection, and water pump can not start or protect shutdown this moment.
Deicer pump, water pump complement structure are identical, but when carrying out ratio heating, sprinkling, motor rotary speed is not necessarily identical, even when the ratio of carrying out 50% is sprayed, because of performances such as deicer pump, water pump, motor, pipe resistance have nothing in common with each other, process is set in the correction of the flow counter of deicer pump, exit of pump to motor rotary speed, thereby guarantees that the deicing liquid ratiometric is accurate.
In ice detachment, if close spray gun, after PLC detects feedback signal, fetch boiling water return flow solenoid valve 10, electromagnetic valve 29, hot water and deicing liquid are back in water tank and the deicing liquid case separately, same when spray gun is opened after PLC detect closing volume electromagnetic valve behind the signal of feedback, thereby hot water and deicing liquid mixing then spray from spray gun.
