Abstract
The utility model relates to a tracking oil consumption meter which is an instrument used for measuring the oil consumption of an engine. For the utility model, under the control of a computer, a stepping motor drives a photoelectric sensor to track the change of the liquid level of a measuring tube communicated with a measuring cylinder to calculate the temporal flow rate. The utility model which has the advantages that the measuring precision is high, the resolving ability is irrelevant wth the measuring range, and the flow rate of any prescribed time can be measured can be used for the measurement of the oil consumption of an engine or other liquid.
Description
The utility model is to measure the instrument that engine fuel consumes.
It is to utilize the elapsed time of measuring a constant volume fuel oil to calculate fuel flow (kilogram/hour) that positive displacement fuel consumption meter, common way are used in engine fuel consumption quantity measurement at present.But petrol engine is under the powerful operating condition of high rotating speed, move very dangerous, therefore the user wishes in the fuel consume test, in a single day the test period (20 seconds) that reaches national regulation the duration of runs of engine just finishes test, and the measuring method of constant volume survey time can make Measuring Time substantially exceed the national regulation time, and this has just increased the insecurity of engine test.Occurred a kind of regularly fuel consumption meter of intermittent gauging volume in recent years again in order to address the above problem, it is to utilize the fluid pressure under the fuel measurement pipe to come the interior liquid level of perception measuring tube.Calculate the fuel oil volume according to the variation of liquid level in the Measuring Time then.The subject matter of this instrument is to measure the pressure transducer range of fluid pressure and the contradiction of resolution, can not accomplish that promptly the existing enough measurement volumes of instrument can have enough definitions so that reach the measuring accuracy of hope again when little volumetric measurement.
The purpose of this utility model provides a kind of novel tracking mode fuel consumption measurement instrument, and it can measure the flow of any stipulated time, and definition and range are irrelevant.
The liquid level tracking means that the stepper motor driven photoelectric sensor that close the graduated cylinder metal line position setting of the fuel consumption meter that the solenoid valve that main points of the present utility model are refueled to graduated cylinder by graduated cylinder and control and the photoelectric sensor of monitoring liquid level are formed is controlled by computer is formed.Another characteristics of the present utility model are, for the ease of making and improving measuring accuracy, above-mentioned tracking means is the liquid level position of following the tracks of at the measuring tube that is communicated with graduated cylinder, and the sectional area of this measuring tube is much smaller than the sectional area of graduated cylinder.
Advantage of the present utility model, owing to be to follow the tracks of liquid level with the liquid level monitoring arrangement that stepper motor driven photoelectric sensor is formed, so have: (1) is the intermittent gauging volume regularly.(2) no matter each the measurement with how much oily can be realized high-acruracy survey equally.Another characteristics of this instrument are to survey the oil mass tube to separate with measuring tube, because measuring tube needs to make with glass, be difficult to guarantee that the diameter of pipe has very high degree of accuracy, and graduated cylinder can be made with metal, can Precision Machining to guarantee accuracy to size, because the sectional area of graduated cylinder is much larger than the sectional area of measuring tube, thereby a small amount of error of measuring tube is very little to the influence of volumetric measurement.The utility model compared with prior art has the fuel consumption that can measure any stipulated time, and definition is with to measure volume irrelevant, the measuring accuracy height, and advantage such as error is little can be widely used in the fuel consumption measurement of engine, and other fluid floies detects.
Accompanying drawing is a tracking mode fuel consumption meter structural representation.1-solenoid valve among the figure, 2-graduated cylinder, 3-measuring tube, 4-photoelectric sensor, 5-drive link, 6-stepper motor.
Below in conjunction with accompanying drawing and embodiment the utility model is done statement further.As seen from the figure, the fuel oil of fuel tank refuels for graduated cylinder 2 by solenoid valve 1, at this moment liquid level and graduated cylinder in the measuring tube 3 that is communicated with graduated cylinder rise simultaneously, when liquid level arrives the extreme higher position, solenoid valve cuts out automatically, along with the engine fuel consumption, liquid level descends in the graduated cylinder, and the liquid level in the measuring tube also descends simultaneously.The computer expert crosses photoelectric sensor 4 surveillance and tracking measuring tube liquid level positions in during measuring.In case liquid level is lower than the photoelectric sensor monitored position, computer just orders stepper motor 6 to take a step forward, motor by drive link 5 for example leading screw drive photoelectric sensor and move down certain distance.When liquid level descended continuously, stepper motor just drove photoelectric sensor step by step and follows liquid level to descend, and computer just can be calculated the distance that liquid level descends by the step number that stepper motor advances in certain Measuring Time like this, thereby calculates the volume of fuel consume.Because the stepper motor revolution need be walked fixing step number, for example, 240 steps, as leading screw pitch be 1 millimeter then stepper motor whenever make a move and be equivalent to photoelectric sensor and move 1/240 millimeter, therefore the tracking mode fuel consumption meter has high definition, no matter how many each liquid level differences of measuring is, can keep such high degree of resolution forever.This has just guaranteed hour also can reach high measuring accuracy measuring volume.
