The principle of work of said structure dispenser system: behind the machine connecting power, when oil gun is raised, the inductive switch closure, after the computer master control board receives and carries the rifle fueling signal, output motor and solenoid control signal make the relay adhesive on the control desk, electromagnetic valve on the oil circuit is opened, motor rotates and drives the oil pump oil pumping simultaneously, may contain air in the oil that draws up through oil separator, outside the gas discharge machine, fuel oil is by the discharge measurement changer under the pressure of pump, the promotion coder rotates, coder is converted to electric impulse signal with the mechanical rotation signal and gives the computer master control board, and computer carries out computing according to the requirement of keyboard to set up, and operation result is shown oil mass on display panel, unit price, the amount of money; Fuel oil comes out through the electromagnetic valve oil gun of flowing through again from the discharge measurement changer, and self-propelled vehicle is advanced in filling.
Therefore above-mentioned conventional single phase power supply fuel charger has following shortcoming owing to adopt single-phase AC220V motor: 1) inefficiency, waste electric energy, 2) the cost height; 3) order cycle time long, selectable producer is few; 4) volume is big, and commonality is not strong; 5) electrical efficiency is low; 6) low voltage can not start (being lower than 170V); 7) self can't realize soft start function.
[utility model content]
The utility model has overcome the deficiency of above-mentioned technology, and a kind of high efficiency is provided, saves energy, and cost is low, the frequency conversion dispenser system of intelligence.
For achieving the above object, the utility model has adopted following technical proposal:
A kind of frequency conversion dispenser system includes computer master control board 1, oil gun switch 2, finger-board 3, display panel 4, measurement translator 5, oil pump 6, oil gun 7, frequency converter 8, three phase electric machine 9.Described oil gun switch 2, finger-board 3, display panel 4, discharge measurement changer 5 all is connected with computer master control board 1, oil gun 7 and oil pump 6 all are connected on the discharge measurement changer 5, and oil pump 6 send oil by discharge measurement changer 5 to oil gun 7 from petrol storage tank 12, and oil gun 7 is used for refueling to self-propelled vehicle.Connect frequency converter 8 and three phase electric machine 9 and be connected between computer master control board 1 and the oil pump 6, these frequency converter 8 input ends are connected with computer master control board 1, and frequency converter 8 mouths are connected with oil pump 6 by three phase electric machine 9 backs.
The beneficial effects of the utility model are:
1), high efficiency, saves energy reduces the operation cost at oil station, improves economic results in society, responds national energy saving policy.
2), reduce the cost of product, the cost of three-phase AC220V motor has only 1/3 of single-phase AC220V motor, the cost of frequency conversion plate equals the cost of electromagnetic valve+original drive plate.
3), reduce asphalt channel fault rate, lifting product market competitiveness.
4), increase the soft starter for motor function, reduce the impact of motor to pump and belt.
5), solve conventional fuel charger and can't work down in low voltage (AC150V), enhance product performance.
