Working procedure:
With hydraulic shovel in ambient temperature-20 DEG C ~-30 DEG C district works, main fuel tank 1 add as 0# diesel oil, drop tank 2 to add as-35# diesel oil be that example is described.
Engine warming up: switch starter is opened to " ON " shelves, powered to fuel heater 5 by storage battery, motor in fuel heater 5 drives the oil pump of its inside that the fuel oil in drop tank 2 is delivered to atomizer through transport pipe, the air sucked with combustion-supporting fan after fuel-oil atmozation mixes in firing chamber, lighted by red-hot glow plug, through the radiating fin of water jacket inwall, heat is passed to the cooling liquid in water jacket samdwich, by the water intake 4d by water outlet 5b supply engine assembly 4 under the effect of water water pump or thermoconvection in fuel heater 5 of heating, drop tank 2 so just can be made to 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 starts: switch starter is opened to " ON " shelves, oil outlet 8c and the filler opening 8b of fuel-displaced selector valve 8 connect, filler opening 3a and the oil outlet 3b of oil return selector valve 3 connect, the oil suction from drop tank 2 of oil and water seperator 7 having electronic pumps is exhausted system, continuous pressure, the oil pipe of whole system is made to be full of-35# diesel oil, treat that motor reaches cranking temperature, motor just normally can start, work.
Main fuel tank 0# diesel oil switches: after engine work, powered to electromagnetic heater 9 by generator, heat main fuel tank 1 fuel oil, the fuel oil that the cooling liquid of engine assembly 4 is introduced in radiating fin 10 pairs of main fuel tanks 1 of main fuel tank 1 inside simultaneously carries out Synchronous Heating.Also can be heated by the fuel oil in hydraulic oil return tube 18 pairs of main fuel tanks 1 after the oil temperature in hydraulic system raises simultaneously, after near fuel oil oil outlet, temperature transducer 11 detects that oil temperature is raised to predetermined temperature, as 6 DEG C, oil outlet 8c and the filler opening 8a of fuel-displaced selector valve 8 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 about 90% fuel oil can flow back to fuel tank after motor, designed by the drop of oil return steel pipe 12 and drainage tube 13, make oil return by near the filler opening 1b that flows to main fuel tank 1 after oil return steel pipe 12 along the inwall of drainage tube 13, such return flow oil just can directly be back near main fuel tank 1 filler opening 1b, and then improves the oil temperature supplying of main fuel tank 1.After main fuel tank 1 fuel temperature sensor 11 detects that temperature is raised to certain value, as 25 DEG C, stopping is heated by electromagnetic heater 9, and water pipe first ball valve 15 or second ball valve 16 of engine assembly 4 connection simultaneously cut off, and stop heating main fuel tank 1.Engine assembly 4 carries out fuel feeding work by main fuel tank 1.
Motor is shut down: motor needs to guarantee to be full of-35# fuel oil in whole fuel piping system before shutting down, and prevents low temperature wax deposition.Therefore shut down first 10 minutes, first fuel-displaced selector valve 8 is switched to drop tank 2, and because the recirculating oil quantity of machine is very large, within about 3 ~ 5 minutes, just the 0# fuel oil of whole oil circuit can be emptied, now oil return selector valve 3 is switched to drop tank 2.After operation a period of time, just can shut down.
According to above-mentioned work cycle, motor cold start-up at low ambient temperatures can be guaranteed, be completed the switching of engine fuel after starting by the circulating-heating of the 0# fuel oil to main fuel tank 1, well solve the fuel feeding problem of 0# fuel oil at low temperature environment; Simultaneously by controlling the process of shutdown, avoiding shutting down after-burning oil circuit wax deposition, solving the fuel oil fault existed when again starting.The application of whole system, can meet excavator uses high trade mark fuel oil problem at low temperature environment completely.
