This structural configuration is from Electromagnetic oil transfer pump oil-feed head, transduce to the oil and water seperator outer chamber by accepting on the carriage U type oil guiding hole, after filtration, divide water layer to oil and water seperator inner cavity chamber, transduce to oil out port through the guide hole of accepting carriage, form a sealing oil duct, filler opening is connected by the oil-feed transport pipe with oil transportation conduit in the fuel tank, and oil outlet is connected by fuel-displaced transport pipe with mechanical oil transfer pump.Under the effect of Electromagnetic oil transfer pump plunger, the fuel from fuel tank pump is to oil and water seperator, after filtration, divide water, heating to be conducted to motor.
When electric control room gets, automatical control system drives the defeated pump plunger work done under the effect of Returnning spring of electromagnetism oil, makes one-way valve opens-close, and fuel from fuel tank is sucked in the electromagnetic pump oil cylinder, form oil pressure pump to oil and water seperator, after filtration, divide water after gadgetize pump oil defeated until jet pump.When oily temperature was higher than 2 ℃, 0# diesel oil can not hung wax and cold junction, and electric control room temperature control system output terminal does not have voltage output, not work done of heating part.When oily temperature was lower than 2 ℃, the heating system energising added pyrolysis wax, and outage stops heating when oily temperature is higher than 30 ℃.Thereby make oily temperature remain on the circulation status of not hanging wax, under the effect of electromagnetic pump, and then oil circuit cleaning, unimpeded supply have been ensured, locomotive just can use the low grade fuel oil under rugged environment, reach the work effect of high grade fuel oil, constituted thus that collection pump oil, exhaust, heating, filtration, branch water are multi-functional to be the Integrated electromagnetic pump of one.
Described Integrated electromagnetic pump automatical control system working principle: as shown in Figure 3, be made up of automatic pump EFM Electronic Fuel Management and automatic temperature-controlled heating system two-part, working principle division is as follows separately for it:
One, automatic pump oil Control work system principle: automatic pump oil control section is made up of programmable microcomputer chip U1, power amplifier output module U2, thermistor R8, operational amplifier U3A, triode Q1 and associated peripheral electronic element.According to the characteristic requirement of Electromagnetic oil transfer pump, by the programmable software mode, make the U1 chip export one group of timing output pulse control signal with certain frequency, amplitude, pulsewidth, its timing controlled time is 15 minutes.This pulse control signal is exported through U2 power amplifier output module, make pump oil coil under certain frequency of okperation, produce alternating magnetic field, plunger back and forth movement under the effect of magnetic field and Returnning spring in the coil, making the pump internal check valve follow action open-closes, fuel from fuel tank is sucked through oil inlet pipe, form oil pressure and send into mechanical oil transfer pump until jet pump through oil and water seperator.When needs were opened oil pumping system work, the opening power control switch got final product, and automatic pump oil can be closed after 15 minutes automatically, and this moment, locomotive worked well, by mechanical oil transfer pump pump oil.If when needing once more pump oil, only need close and open the input power switch once more and get final product.For guaranteeing the permanently effective work of native system energy, this circuit design has multinomial protection control function.One: U2 power amplifier output module itself has overcurrent, overvoltage protection control function.Its two: formed overtemperature prote control function by thermistor R8, operational amplifier U3A, triode Q1.When temperature in the pump housing surpassed 160 ℃, U3A export high level, triode Q1 conducting, and 2 pin input signals of U2 module are by short circuit at this moment, this module non-output signal, electromagnetic pump quits work.Have only when temperature in the pump housing is reduced to below 130 ℃, the U3A output low level, triode Q1 ends, the normal state of a control of U2 module recovery this moment, oil transfer pump begins proper functioning.
Two, automatic temperature-controlled heating work principle: according to the requirement of oily temperature control characteristic, the design has selected the hysteresis comparator control mode with adjustable return difference control characteristic for use, to realize the automatic temperature-controlled heating function of fuel oil.Its implementation: formed the hysteresis comparator control circuit with amplifier module U3B, peripheral cell R10～R16, D7, realized detection and the control of high low temperature range to the oil temperature, R14 is that the oil temperature detects thermistor.Form ON-OFF control circuit with triode Q1, relay K 1, realize closing control heating.1. cold-starting heating control principle: do not hang wax and characteristic that can be unimpeded when 2 ℃ of the ambient temperatures according to 0# diesel oil, this circuit parameter is arranged on and starts heating when ambient temperature is lower than 2 ℃.Promptly when ° c of ambient temperature≤2, by the magnitude of voltage that is detected on R10 and the thermistor R14, will be greater than setting partial pressure value by R12 and R15, be that comparator U3B in-phase end 5 pin input voltages are greater than its end of oppisite phase 6 pin input voltages, 7 pin of comparator U3B are output as high level, triode Q1 conducting, relay K 1 adhesive, its normally opened contact closure is connected the electric heater energising and is heated up.2. high temperature stops to heat control principle: hysteresis comparator control is that high temperature stops to heat basic principle, the magnetic hysteresis comparison circuit of being made up of D7, R16, R10, R14, U3B; When oily temperature be heated to 〉=30 ℃ the time, comparator U3B in-phase end 5 pin input voltages are less than its end of oppisite phase 6 pin input voltages, 7 pin of comparator U3B are output as low level, triode Q1 by, relay K 1 discharges, and its normally opened contact disconnects, electric heater outage stopping heating.
Whole low pressure from fuel tank to mechanical oil transfer pump is supplied with oil circuit, under the effect of the heating of Integrated electromagnetic pump, filtration, branch water, pump oil, exhaust, constitute one and do not hung wax, cleaning, unimpeded supply oil circuit, provide one to start and the good condition of work for the oil-fired system of locomotive.
Important technological parameters: nominal voltage 24V, total output: 720W, pump oil output power: 120W, maximum heating output power: 600W, pump oil pressure: 〉=0.12Mpa, flow: 〉=3L/min.
