In the present embodiment, the fuel tank taking fuel delivery as 500L/min is example, and lower oil level switch 8 is fixingBe arranged on the interior 50～60cm oil of described fuel tank bit position, upper oil level switch 9 is fixedly installed on described oilIn case, on 65～75cm oil bit position, temperature sensor 702 is arranged in described fuel tank and Real-time CollectionOil temperature in described fuel tank.
When the phase sequence of three phase mains and the phase sequence of disconnected phase and phase sequence controller 4 are when inconsistent, control transformer5 must not be electric, therefore described electric-control system cannot start. Only when changing phase sequence and the disconnected phase and phase of three phase mainsThe phase sequence one of sequence controller 4 is shown while meeting the requiring of pumping plant, control transformer 5 electric, described automatically controlledSystem normally starts.
After described electric-control system starts, temperature controller 701 obtains electric, and temperature controller 701 self-inspections there is noTemperature controller self-inspection alarm actuating contact 703 closures when warning.
When the oil level in described fuel tank is during higher than upper oil level switch 9, lower oil level switch 8 and upper oil level switch9 is all closed, the first auxiliary reclay coil 1001 and the second auxiliary reclay coil 1101 all electric,So that the first auxiliary reclay normally-closed contact 1002 is disconnected, the first auxiliary reclay normally opened contact 1003Closed;
Now, press the start button that is electrically connected to the first ac contactor coil 102, the first interchange connectsTentaculum coil 102 obtains electric, the closed self-locking of the first A.C. contactor main contacts 103, and Oil pump electrical machinery starts alsoFuel feeding, motor indicator lamp 104 is lighted;
While having served as live circulation overtemperature relay 105, thermal relay normally closed contact 106 disconnects, thereby willOil pump electrical machinery 101 disconnects and stopping, and plays the effect of overload protection.
The second auxiliary reclay coil 1101 electric after, two the second auxiliary reclay normally opened contacts 1102All closed;
Now, if the oil temperature that temperature sensor 702 gathers lower than the preset temperature of temperature controller 701Value, temperature controller temperature control contact 704 closures, are electrically connected to respectively two the second auxiliary reclays and often openThe stacked switch closure of contact 1102, the second ac contactor coil 202 and the 3rd A.C. contactor lineCircle 302 obtains electric, and the second A.C. contactor main contacts 203 and the 3rd A.C. contactor main contacts 303 all closeClose, corresponding primary heater 201 starts and heats with secondary heater 301, primary heater instructionLamp 204 and secondary heater indicator lamp 304 are all lighted;
Described stacked switch turns clockwise 45 ° and sends the heating order of closing a floodgate, and turns counterclockwise 135 ° and sends and addHot separating brake order.
In the time that the oil level in described fuel tank is between upper oil level switch 9 and lower oil level switch 8, upper oil level is openedClose 9 and disconnect, lower oil level switch 8 closures, only the first auxiliary reclay coil 1001 obtains electric;
Now, under the normal work prerequisite of temperature controller 701, temperature controller self-inspection alarm actuating contact703 closures, Oil pump electrical machinery 101 can start, but two heaters cannot start, and therefore can not give instituteState the string washing oil heating in fuel tank.
When the oil level in described fuel tank is in the time that lower oil level switch is below 8, upper oil level switch 9 and lower oil level are openedClose 8 and all disconnect, the first auxiliary reclay coil 1001 and the equal dead electricity of the second auxiliary reclay coil 1101;
Now, Oil pump electrical machinery 101 and two heaters all cannot start, and because of the first auxiliary reclay normalClosed contact 1002 closures, alarm lamp 12 is lighted, and buzzer 13 sounds, and prompting user carries out phaseClose and process.
Described electric-control system is providing two cover protections aspect the control of electric heating tube, the first auxiliary reclay is normalOpen contact 1003 and connect with the second auxiliary reclay normally opened contact 1102, therefore must meet upper oil level and openClose 9 and lower oil level switch 8 when all closed electric heating tube just can work.
Temperature controller 701 with PID control (Proportion-Integration-Differentiation,Proportional-integral-differential control), be conventionally set as PD control (Proportion-Differentiation, thanThe control of example-differential), at this moment by the time of integration I be set as 0, in order to prevent that oil temperature is reduced in preset temperatureNear the frequent output heating of temperature controller 701 control action value time; Proportionality constant P, oil temperature is regularWhen fluctuation, increase proportionality constant, be conventionally set as 10; Derivative time, D increase contributed to minimizing system superTemperature, sets up and is decided to be 15; Control cycle T, in general considers its machinery with the control cycle of ac contactorIn the life-span, be conventionally set as 10.
Described electric-control system, on the basis of an oil level switch in the past, increases an oil level switch string is washedIt is therefrom independent that oil adds thermal control function, and described electric-control system guaranteed when oil level is during higher than high oil level,Oil pump electrical machinery can start, and also can give the heating of string washing oil; Between low oil level and high oil level time, can onlyStart Oil pump electrical machinery, can not give the heating of string washing oil; When oil level is during lower than low oil level, Oil pump electrical machinery and electricity addHeat pipe is not worked.
Such mode has prevented in the oily process of string effectively because of the low easy burn-out pasta of oil level in fuel tank districtThe phenomenon of the electric heating tube in territory, the phenomenon of damaging after the oil pump unlatching that has also prevented from causing because oil level is low,Deliver for a check equipment guarantee is provided for ship piping system throwing oil, also make to throw oils equipment and be convenient to maintaining simultaneously.
Although more than described detailed description of the invention of the present utility model, those skilled in the art shouldWork as understanding, this only illustrates, and protection domain of the present utility model is to be limited by appended claims. Those skilled in the art is not deviating under the prerequisite of principle of the present utility model and essence, can be rightThese embodiments are made various changes or modifications, but these changes and amendment all fall into of the present utility modelProtection domain.
