Description
Technical field
The utility model relates to a kind of diesel motor practical oil consumption pick-up unit, and specifically a kind of to be used for detecting be the car of power, the practical oil consumption of ship with diesel motor.
Background technology
The measuring method that can realize engine fuel consumption quantity at present mainly contains following several: 1, Weighing type, namely equivalent the fuel oil taking constant weight and after engine operation a period of time, again take the weight of current excess oil, obtain engine actual fuel consumption within a certain period of time by the difference of front and back weight; 2, electronics measuring and calculating formula, namely obtains parameters such as sending out machine delivery temperature, engine speed, vehicle wheel rotational speed, and draws the fuel consume of vehicle as calculated; 3, flow detection formula, namely installs turbine type flow detecting sensor in the petroleum pipeline of engine, detects the flow velocity of fuel oil in pipe, then calculates the flow of the fuel oil in pipe according to caliber, these parameters of flow velocity; 4, positive displacement, its Cleaning Principle type detects in above-mentioned Weighing type, just taking of weight is become measuring of volume.
The defect that these modes above-mentioned existence is more or less certain and deficiency.Under the working condition that Weighing type detects in reality, all require that vehicle to be under the state of stopping or metastable running status weighing and revising detected parameters of just Absorbable organic halogens, the vibration caused in the process of moving can havoc accuracy of detection; Electronics measuring and calculating formula require have multiple sophisticated sensor carry out simultaneously measurements detection, as a kind of reality daily consumption detection device not-so-practical; Flow detection formula requires the flow sensor with degree of precision, but the detection degree of accuracy of this kind of sensor is by temperature, the caliber of oil pipe, the relative height of installation, the rotating speed of engine, rotating speed height causes the height of oil pipe flow velocity, etc. the impact of aspect comparatively large, often installing one all needs calibration and debugging.And the detection method of positive displacement, the method carries out surveying work by the liquid detecting unit volume, there is the not vibrated advantage affected with other external condition, but the liquid how obtaining unit volume is reliably the basic problem that requirement solves also is fundamental purpose of the present invention.
Utility model content
The utility model is subject to mainly for the measuring method of existing diesel oil consumption the problem that external condition is disturbed and error is large, provides a kind of diesel motor practical oil consumption pick-up unit.
The utility model is the technical scheme taked that solves the problem:
A kind of diesel motor practical oil consumption pick-up unit, by synchronous driving motor, two oil consumption counting assemblys and master control board composition, two oil consumption counting assembly symmetries are arranged on the left and right sides of synchronous driving motor, each oil consumption counting assembly is by outside magnetic patch, a rotary blade, impeller housing, magnetic drives dish and Hall element composition, outside magnetic patch is contained in the rotating shaft of synchronous driving motor, rotary blade and magnetic drives dish is fastening is installed together, magnetic drives dish is placed on the outside of outside magnetic patch and magnetic drives dish and outside magnetic patch carry out the coupling of power by magnetic force, rotary blade is installed in the working chamber in impeller housing, each blade of rotary blade and impeller housing are tightly connected and form a closed cavity, Hall element is contained on impeller housing, master control board is connected with synchronous driving motor opening with control synchronization drive motor, stop and rotating speed, master control board is also connected with two Hall elements, the rotary blade of collection is rotated the number of turns and all sends master control board to by two Hall elements, master control board is calculated oil consumption numerical value according to the rotation number of turns of rotary blade and is shown by external-connection displayer.
The utility model adopts technique scheme, during use, the oil pick-up tube serial between engine and fuel tank is accessed on one of them Hall element, and the scavenge pipe serial between engine and fuel tank accesses on another Hall element, such hypothesis rotary blade often revolves and turns around, output be the oil mass of a milliliter.Under operating conditions, the Hall element be connected with oil pick-up tube detects the signal that N encloses, and the Hall element be simultaneously connected with scavenge pipe detects the signal that M encloses.Because whole fuel oil parts for the extraction of engine in real process are directly consumed by engine, and remaining fuel oil returns to fuel tank, so recirculating oil quantity is necessarily few than oil pumping amount, namely N>M is so draw: N-M*a=engine consumption mL.
Between rotary blade of the present utility model and impeller housing, the independent sealed cavity formed one by one realizes the output of quantitative volume simultaneously, but sealed cavity can cause the friction loss of rotary blade when rotating to strengthen, therefore the utility model introduces synchronous driving motor and rotates for offsetting rotary blade the friction produced, simultaneously rotary blade and synchronous driving motor transmission be carry out coupling by magnetic force, so two oil consumption counting assemblys there is no produce leakage other root to improve the security performance of product further.The utility model master control board is the core control part of this electromechanical integration equipment, the startup stopping of master control board control synchronization drive motor and the speed of rotation.Therefore, compared with prior art, the utility model has accuracy of detection and is not affected by the external environment, and in whole life cycle, accuracy of detection also can not change, and installs simple advantage.
