Description
Technical field
The present invention relates to lubricating oil analytical equipment, particularly relate to a kind of lubricating oil Consumption Analysis device.
Background technology
In working process of diesel engine, the use of lubricating oil is absolutely necessary.The heat that some parts produces can be taken away by lubricating oil in course of conveying on the one hand, on the other hand, is also most important one side, and the parts that two relative motion occurs can be kept apart by oil film bearing capacity by lubricating oil, reduce friction loss.And it is few for the change of properties research of the lubricating oil of lubricating oil in working process of diesel engine, fundamentally cannot carry out rational anticipation to diesel engine lube use rate, this materially increases diesel engine in the course of the work because the piston ring carbon deposition phenomenon that scuffing of cylinder bore or the excessive lubricating oil caused of lubricating oil supply burn in a large number and produce appears in lubricating oil undersupply.Analyze according to the concrete condition of different types of lubricating oil in real work, from reasonable arrangement oil feed to a great extent, energy-saving and emission-reduction can be realized.
Present stage, generally be to the analysis and research of diesel engine lube use rate the laboratory study stage, and these researchs are launch around the inner molecular structure of lubricating oil and the intrinsic property such as density, viscosity mostly, lack the practical studies combined with engineering.
The domestic and international analytical equipment for diesel lubrication oilconsumption is generally divided into the test-bed of the mathematical theory analytical equipment of theoretical analysis and the real ship of real vehicle at present.Wherein mathematical theory analytical equipment can calculate the intrinsic property of the lubricating oil of given kind, is inferred and anticipation lubricating oil consumption by the method for gauging surface tension force and vibration natural frequency.China Science & Technology University Zhang Dong once mentioned laboratory stage and utilizes Doppler acquisition instrument to observe the lubricating oil regularity of distribution to judge lube use rate in its PhD dissertation " experimental study of biomass pyrolysis oil spray burning and gasification and numerical simulation ".The test-bed of the real ship of real vehicle is then under the prerequisite of known lubricating oil input quantity, according to the diesel engine that running preset time is truly given, by evaluating lubricating oil the spatter property of the postrun abrasion condition of diesel engine or the parts such as piston, piston ring groove, and combine to collect lubricating oil amount with input lubricating oil amount do difference calculate actual lubricating oil consumption figures.Detailed description is given for diesel engine oil consumption assay method (GB/T14636-2009) in " the People's Republic of China's national standard " that in March, 2009 is issued.The assay method related in this standard is the mensuration of real machine or real ship.Although above-mentioned method can have certain effect to lubricating oil consumption research, the theory calculate of laboratory stage has departed from the working environment of itself, can not comprehensively analyze lubricating oil Expenditure Levels.And the analytic approach of test-bed often needs real vehicle or real ship continuous working more than 20 hours, larger for human and material resources real vehicle or real ship, financial resources consumption.In addition in diesel engine operation process, operating mode is extremely unstable, and any sudden change all can have an impact to lubricating oil consumption, so for the same equipment same working time, measurement result is also not quite similar.
Summary of the invention
The object of the invention is, in order to the method in conjunction with intrinsic property theoretical analysis device and actual tests stand, analyze diesel lubrication oilconsumption and a kind of lubricating oil Consumption Analysis device is provided.
The object of the present invention is achieved like this: comprise the cylindrical shell with sealing bolt, be arranged on the end cap of the cylindrical shell upper end with sealing bolt, be arranged on the base of the cylindrical shell lower end with sealing bolt, be arranged on the gas feed on the barrel outer surface of sealing bolt and the petroleum pipeline being arranged on the inner barrel with sealing bolt, the upper end of described petroleum pipeline is connected with oil-in, the bottom of petroleum pipeline is connected with oil thrower, petroleum pipeline is also provided with four grooves, and four grooves are symmetrical arranged along the outside surface of petroleum pipeline, the gas entered through gas feed enters oil thrower after described groove mixes with lubricating oil in petroleum pipeline.
Compared with prior art, the invention has the beneficial effects as follows: 1, the lubricating oil Consumption Analysis technology of present stage employing, be mostly simple theoretical analysis or the analysis of real ship real vehicle, and single analytical approach cannot will be integraded theory with practice.The present invention analytical approach by the intrinsic theory property of selected lubricating oil, as: viscosity, volatile grade, specific heat ratio etc., organically combine with test, by the experimental data under different operating mode, and then draw the conclusion of lubricating oil consumption figures.By the specific lubricating oil consumption of some single operating mode, the lubricating oil consumption figures of unknown operating mode can also be predicted by the method for data fitting.2, oil fog generating apparatus of the present invention is made up of end cap and cylindrical shell, when end cap and cylindrical shell good seal, can form the confined space that has voltage stabilizing function, can externally export the oil mist particles be evenly distributed continuously.3, the oil thrower mentioned in the present invention is the structure of separate removable, the pore size of oil thrower can according to need for the research of the different model diesel engine of research and adjust arbitrarily, avoid petroleum pipeline in original invention to be connected with oil thrower and once change the loaded down with trivial details technological process and the serious wasting of resources that needs all change, also effectively can avoid repeatedly dismantling the situation that the test unit sealing that causes is bad.4, selected in the present invention nitrogen is pure nitrogen, and this both can ensure to provide sufficient pressure, again because its stable chemical nature thus avoid reacting with lubricating oil to affect testing accuracy.
