Working procedure:
With hydraulic shovel in ambient temperature-20 ℃ ~-30 ℃ of district works, the main fuel tank 1 0# diesel oil that adds as, drop tank 2 add as-35# diesel oil be that example describes.
Engine warming up: switch starter is opened to " ON " shelves, by storage battery, to fuel heater 5, powered, motor in fuel heater 5 drives its inner oil pump that the fuel oil in drop tank 2 is delivered to atomizer through transport pipe, the air sucking with combustion-supporting fan after fuel-oil atmozation mixes in firing chamber, by red-hot glow plug, lighted, radiating fin through water jacket inwall, heat is passed to the cooling liquid in water jacket samdwich, heated water passes through the water intake 4d of water outlet 5b supply engine assembly 4 under the effect of the interior water pump of fuel heater 5 or thermoconvection, so just can make drop tank 2 provide oil inflame to carry out circulating-heating to the cooling liquid of engine assembly 4, like this, motor just can reach cranking temperature within very short time.
Engine cold-start starting: switch starter is opened to " ON " shelves, the oil outlet 8c of fuel-displaced selector valve 8 and filler opening 8b connect, the filler opening 3a of oil return selector valve 3 and oil outlet 3b connect, the oil suction from drop tank 2 of 7 having electronic pumps of oil and water seperator is carried out exhaust, continuous pressure to system, the oil pipe of whole system is full of-35# diesel oil, treat that motor reaches cranking temperature, motor just can normally start, work.
Main fuel tank 0# diesel oil switches: after engine work, by generator, to electromagnetic heater 9, powered, main fuel tank 1 fuel oil is heated, and the fuel oil in 10 pairs of main fuel tanks 1 of radiating fin of main fuel tank 1 inside of the cooling liquid of engine assembly 4 introducing simultaneously carries out Synchronous Heating.Oil temperature in hydraulic system also can heat by the fuel oil in 18 pairs of main fuel tanks 1 of hydraulic oil return tube after raising simultaneously, until near temperature transducer 11 fuel oil oil outlet, oil temperature being detected is raised to after predetermined temperature, as 6 ℃, the oil outlet 8c of fuel-displaced selector valve 8 and filler opening 8a connect, filler opening 3a and the oil outlet 3c of the selector valve of oil return simultaneously 3 connect, and fuel oil is switched to the 0# diesel oil of main fuel tank 1.Because electric-control motor 90% left and right fuel oil can flow back to fuel tank after motor, drop by oil return steel pipe 12 and drainage tube 13 designs, near flowing to the filler opening 1b of main fuel tank 1 along the inwall of drainage tube 13 after making oil return by oil return steel pipe 12, return flow oil just can directly be back near main fuel tank 1 filler opening 1b like this, and then improves the oil temperature supplying of main fuel tank 1.Until main fuel tank 1 fuel temperature sensor 11, temperature detected and be raised to after certain value, as 25 ℃, electromagnetic heater 9 will stop heating, and water pipe the first ball valve 15 that engine assembly 4 connects simultaneously or the second ball valve 16 cut off, and stop main fuel tank 1 to heat.Engine assembly 4 carries out fuel feeding work by main fuel tank 1.
Engine shutdown: need to guarantee be full of in whole fuel piping system-35# fuel oil before engine shutdown, prevent low temperature wax deposition.Therefore shut down first 10 minutes, first fuel-displaced selector valve 8 is switched to drop tank 2, because the recirculating oil quantity of machine is very large, within approximately 3 ~ 5 minutes, just the 0# fuel oil of whole oil circuit can be emptied, and now oil return selector valve 3 is switched to drop tank 2.After moving a period of time, just can shut down.
According to above-mentioned work cycle, can guarantee the cold start-up of motor under low temperature environment, after startup, by the circulating-heating of the 0# fuel oil to main fuel tank 1, complete the switching of engine fuel, well solved the fuel feeding problem of 0# fuel oil at low temperature environment; The process of simultaneously shutting down by control, avoids shutting down after-burning oil circuit wax deposition, solves the fuel oil fault existing while again starting.The application of whole system, can meet excavator completely and at low temperature environment, use the problem of high trade mark fuel oil.
