Description
Technical field
The utility model relates to a kind of simulation test machine of estimating the IC engine lubricating oil performance, particularly a kind of simulation test machine of estimating the IC engine lubricating oil high temperature detergency.
Background technology
Engine has the requirement of each side to the performance of the IC engine lubricating oil that uses, and as high temperature detergency, oxidation stability, lubricated resistance to abrasion, corrosion resistivity, from the development of present IC engine lubricating oil, topmost performance is a high temperature detergency.At present, the assessment technique of high temperature detergency has two technology paths: the one, adopt the bench test method, since the needed special-purpose bench test equipment costliness of bench test, the testing expenses height of testing, and the test period is long.The 2nd, in view of the problem of bench test method existence, all estimate the high temperature detergency of IC engine lubricating oil both at home and abroad at the development simulation evaluation method, wish with reliable results economic, that simulation evaluation method acquisition fast can reflect the IC engine lubricating oil performance.
These simulation evaluation methods mainly contain coking plate testing machine, swash plate testing machine, heat pipe experiment machine and dishpan experiment machine etc. at present.Wherein the primary structure of coking plate testing machine is by the inclination lubricating oil fuel tank that the temperature controllable aluminium sheet is housed, oil splasher by driven by motor is formed, by the driven by motor oil splasher, formation testing is splashed high temperature heating, have on the test aluminium sheet at certain angle of inclination, flow from high to low by the formation testing deadweight, under high temperature action, formation testing generates paint film on aluminium sheet, with sediment weight and aluminium sheet cleanliness as deliberated index; The heat pipe experiment machine mainly is made up of the glass tube of syringe pump and temperature controllable, with syringe pump the heated glass pipe is injected in formation testing, formation testing generates coloured paint film in the glass tube of uniform temperature, to generate the shade of paint film in the glass tube as evaluation index; The dishpan experiment machine is made up of the examination dish and the transfer pump of the temperature controllable of the upright position of driven by motor high speed rotating, formation testing rapid diffusion around the mind-set therefrom on the examination dish of high speed rotating (2500r/min), formation testing is flowed out from the examination plate edge, and the paint film by the examination panel surface and the score value of carbon distribution are as evaluation index.Therefore these test methods, exist following four aspect deficiencies: 1, need estimate different grade I. C. engine oils with different test conditions owing to do not form controllable test condition severity gradient on the test interface; 2, the viscosity index improver in the multi-grade oil is influential to test findings; 3, relatively poor to the evaluation effect of high grade I. C. engine oil; 4, do not have to carry out association study with the high temperature detergency of nominal mass grade finished product I. C. engine oil.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned simulation test machine, provides a kind of scope of application wide, can satisfy the simulation test machine that the IC engine lubricating oil high temperature detergency is estimated.
The utility model is achieved in that a kind of simulation test machine of estimating the IC engine lubricating oil high temperature detergency, comprise test casing, motor, the transmission shaft that links to each other with motor, the test board that links to each other with transmission shaft, it is characterized in that: described transmission shaft is for being arranged vertically, and described test board is arranged horizontally; Described test board below is provided with well heater, and the top is provided with oil inlet pipe, draft tube, escape pipe.The draft tube, the escape pipe that are provided with are to be used to test providing of atmosphere.
Above-mentioned test board and above-mentioned well heater spacing are less than 3 millimeters, otherwise the thermal radiation effect of well heater is poor.
Above-mentioned well heater below also is provided with airtight chamber, feeds gas with the joint gap between airtight each parts in it, prevents that the oil smoke that heats the formation testing generation from leaking, and realizes the sealing gland effect.
Below above-mentioned test board, well heater is other that the formation testing storage tank is arranged, this formation testing storage tank communicates with oil-recovery tank, oil-recovery tank is connected with above-mentioned oil inlet pipe through oil pump, to reach recycling of formation testing.
The IC engine lubricating oil high temperature detergency simulation test machine of the utility model development by a driven by motor horizontally rotate test board and a heat block that forms uniform heat-field constitutes the evaluation core cell; Carry formation testing to the test board center by an oil pump, the formation testing of process test board evaluation flows into oil-recovery tank through oil storage tank, is transferred to the oil inlet pipe formation formation testing circulating oil path of test board top again through oil pump.
Principle of work of the present utility model: after installing simulation test machine, the gas diaphragm pump provides experiment required atmosphere; Second step starter motor and the well heater; The 3rd step, after treating that the test board temperature reaches testing requirements, start oil pump, formation testing then enters the test interface of examination disk center from oil inlet pipe, formation testing flows to oil-recovery tank through oil storage tank again because the centrifugal action that the test board rotation forms is forced to flow to the test board edge.Like this; formation testing forms owing to centrifugal action is forced to flow that the test board center is thick on the test board that horizontally rotates, the formation testing film gradient of thin edge and formation testing temperature in test board center is low, edge formation testing temperature is high formation testing thermograde; formation testing has formed the test board center test test condition severity gradient that severity is low, the marginal test severity is high under the acting in conjunction of these two gradients; after the off-test; shut down; take out test board, test findings is estimated with computer expert system.
The utility model can be applicable to the high temperature detergency evaluation of different quality grade I. C. engine oil, can be applicable to the high temperature detergency evaluation of multi-grade oil and single-stage oil, and high temperature detergency and this simulation test machine test findings of different company's commodity nominal mass grade I. C. engine oil there is good consistance; In a word, the utility model is simple in structure, and the test period is shorter, and testing expenses are lower, and can be used for various situations need be to the evaluation of internal combustion engine lubricating oil high-temp detergency.
