Detailed description of the invention
As shown in the figure, a kind of diesel engine external-cycle oil tank structure, it comprises oil separator assembly 2, fuel tank internal oil return intubate 3, froth breaking dividing plate 4, lubricating oil heat exchanger 6 and fuel tank midfeather 9, be divided into front oil storage unit 10 and rear oil storage unit 11 by fuel tank midfeather 9 in the middle part of described fuel tank, fuel tank midfeather 9 welds along aliging with on fuel tank; Described rear oil storage unit 11 comprises fuel tank internal oil return intubate 3, froth breaking dividing plate 4 and diesel engine oil inlet 14, rear oil storage unit 11 is divided into upper and lower cavity two parts by froth breaking dividing plate 4, fuel tank internal oil return intubate 3 to be arranged on below froth breaking dividing plate 4 and to be communicated with oil outlet 13 with the return opening 12 of rear oil storage unit 11, and oil outlet 13 is communicated with by lubricating oil heat exchanger 6 with rear oil storage unit 11 upper cavity section; Described front oil storage unit 10 is provided with oil filling port 011, and fuel lid 012 is arranged on oil filling port 011; Oil separator assembly 2 is arranged on the top of rear oil storage unit 11 and is communicated with rear oil storage unit 11 upper cavity section.
Described oil separator assembly 2 comprises oil separator case 021, filters silk screen 022, disconnector cover plate 023 and air extractor duct adapter 024, wherein oil separator case 021 end opening is communicated with described fuel tank fixed seal connection, filter silk screen 022 and be arranged on oil separator case 021 inside, disconnector cover plate 023 is tightly connected with oil separator case 021 is suitable for reading, and after making fuel tank, oil storage unit 11 forms relative confined space.
The present invention also comprises electric heater 7 and Oil-temperature control device, and electric heater 7 is arranged on the bottom in described fuel tank, and Oil-temperature control device is arranged on electric heater 7.
The present invention also comprises return oil filter 1 and Inlet oil filter 5, and return oil filter 1 is connected with the return opening 12 of rear oil storage unit 11, and Inlet oil filter 5 is connected with diesel engine oil inlet 14.
Also comprise liquidometer 8, liquidometer 8 is arranged on the front panel of front oil storage unit 10, for observing measurement.
Described fuel tank midfeather 9 length is 3/4 of fuel tank height, because oil storage unit 10 and rear oil storage unit 11 are before this UNICOMs in bottom.
Described front oil storage unit 10 respectively accounts for fuel tank 1/2 space with rear oil storage unit 11.
The fuel lid 012 of described front oil storage unit 10 is provided with from return opening mechanism 013, opens reset for fuel lid 012.
Working process: the lubricating oil of diesel motor suction exports out to enter after return oil filter 1 through diesel engine from Inlet oil filter 5 and enters in lubricating oil heat exchanger 6 through fuel tank internal oil return intubate 3, oil storage unit 11 upper cavity section after entering to enter from oil nozzle 15 after interchange of heat, after the filtration of froth breaking dividing plate 4 froth breaking and oil separator assembly 2, the gas of the cleaning of process sheds through air extractor duct adapter 024, a fluid part of having filtered oil gas is stored in front oil storage unit 10, and a part enters diesel motor from Inlet oil filter 5 again through diesel engine oil inlet 14.
Diesel engine dump pump is in the process of pumping lubricating oil, also aspirated a large amount of crankcase inner air simultaneously, therefore powerful impulse fluid liquid level can be produced at the oil-gas mixture that oil nozzle 15 place is a large amount of, if there is no the Oil-gas Separation of froth breaking dividing plate 4 and stop buffer action, can do not entered diesel engine along with fluid secondary by the bubble be separated in time in fluid, serious meeting causes the decline of diesel lubrication oil pressure.Oil separator assembly 2 on rear oil storage unit 11 designs to make isolated oil gas from fluid further be separated, and being separated the gas of discharging outside oil box through this has been clean gas, can not form secondary pollution to test room air.
Due to the buffer action of fuel tank midfeather 9, the fluid liquid level in front oil storage unit 10 space can keep geo-stationary.Therefore, fuel lid 012 and oil filling port 011 all design on front oil storage unit 10, can open fuel lid 012 at any time and refuel in working process of diesel engine, and fuel lid 012 goes back design and installation from return opening mechanism 013, folding with convenience is quick, and case lid sealing is tight.Liquidometer 8 designs on fuel tank front panel; Diesel engine oil inlet 14 designs at fuel tank front lower portion.Electric heater 7 is arranged on the connection position, bottom of front oil storage unit 10 and rear oil storage unit 11 in addition.
The present invention a kind ofly stores and Oil-gas Separation and custom-designed for lubricating oil when solving the work of high-power automotive diesel engine, and incidentally oil filtrating and Oil-temperature control function.This outer circulation Oiltank structure is compact, and good looking appearance is multiple functional, is applicable to all high-power automotive diesel engines and supports the use.After using the present invention, diesel engine, when carrying out indoor stand test or at other on-the-ground test, can greatly reduce the pollution of oil gas to environment, avoids the abnormal reduction of lubricating oil pressure, decreases the loss of lubricating oil simultaneously.Due to this fuel tank first half fluid liquid level ripple disable, therefore can by the consumption of the measure of the change lubricating oil of the observation fluid electrolyte level value of certain hour.
