Description
Technical field
The present invention relates to a kind of pick-up unit, concrete, the present invention relates to a kind of engine motor oil pick-up unit, described engine motor oil pick-up unit is specially adapted to the detection of the engine oil pressure and the oil temperature of vehicle motor main oil gallery.
Background technology
For guaranteeing the normal operation of engine, engine oil needs to detect.Engine oil detects and also relates to the hydraulic oil detection, and gear oil detects, and compressor oil detects oil liquid monitoring.Its technology contents is: with equipment lubrication oil or the actuating medium sample that collects, utilize means such as light, electricity, magnetics, analyze its physical and chemical index, detect entrained wearing and tearing and contaminant particle, thereby obtain the information of the lubricated and state of wear of machine, qualitative and describe the state of wear of equipment quantitatively, find out risk factor, estimate operating mode and its fault of prediction of machine, and definite trouble location, reason and type.
Engine motor oil has functions such as cooling, lubricated, cleaning, sealing, and it is for guaranteeing that the normal work of engine plays crucial effects.Along with the increase of engine operating duration, engine motor oil is owing to the influence of factors such as the wearing and tearing fine particle of high-temperature oxydation, mechanical component, fuel-steam corrosion is polluted.In addition, engine motor oil during normal use also will have certain consumption.On the other hand, daily detection and maintenance that machine oil is correct will prolong life-span of engine, guarantee its power performance etc.
Particularly, motor car engine engine oil pressure deficiency can cause lubricant effect to descend, and engine components are produced infringement.Beyond this phenomenon is removed and caused by the oil level deficiency, also may be that the bad or filter cleaner of lubricating oil pump is freeed due to the reasons such as obstruction.
In the past, general machine oil detection method was as follows:
(1) car is parked in dead level, treats to detect with oil rule behind the engine stoping operation number minute.Mark is if in the middle of H and L, and then oil level is normal.Be higher than H, machine oil is excessive.Be lower than L, the machine oil deficiency.
(2) if oil level is normal, then need machines oil pump or bayonet gauge induction plug whether to have fault.
(3) the machine oil induction plug on the engine is unscrewed,, the induction plug existing problems are described then if the interface organic oil flows out.If inorganic oil flows out, lubricating system existing problems such as lubricating oil pump are described then.
(4) cycle of normal more change engine oil is changed once for the 4000-5000 kilometer that whenever travels.But because machine oil in use can be because of burning, reasons such as oxidation cause the impurity generation that engine oil quality is descended.Therefore, the 800-1500 kilometer that whenever travels preferably detects once machine oil, if find machine oil blackening or machine oil filler adhesion is arranged, and then needs machine oil is changed.
In addition, tested as follows respectively to the pressure of high speed and low speed machine oil in the past.
Pressure in high speed 1500rpm, low speed 300rpm (concrete rotating speed needs engine calibrating test to determine) test engine main oil gallery carries out time and frequency domain analysis to the data of gathering.
The purpose of described test is test machine oil pressure-release valve function and lubricant passage way fault, and checkable fault comprises: oil pump gear fault, lubricating oil pump leakage, machine oil pressure-release valve fault, neglected loading bearing, pipeline leakage etc.
Yet the test of high speed and low-speed machine oil pressure all can use oil temperature to compensate.Because the oil pressure of engine interior is relevant with the viscosity of oil, just relevant with the oil temperature, therefore in order to use correct engine oil pressure and limit value to compare, must use oil temperature that engine oil pressure is revised.
As mentioned above, in the cold survey of motor car engine, need measure the engine oil pressure and the temperature of engine main oil gallery simultaneously.In order to satisfy the requirement of online detection, need measuring mechanism can realize fast, accurately purpose simultaneously.
