Abstract
The utility model discloses a calibrating instrument for the comprehensive parameter tester of the diesel engine. The utility model is characterized in that the utility model comprises a speed regulation motor, a coupling rotating disk, an oil injection pump, a high-pressure oil tube, an oil nozzle, an oil delivery tube, a measurement sensor and a display; the output end of the speed regulation motor, the front side of the coupling rotating disk, the back side of the coupling rotating disk and the front end of the oil injection pump are connected through a shaft coupler; the fuel injection pump, the high-pressure oil tube, the oil nozzle, an oil tank and the oil delivery tube are connected end-to-end to form a loop. The utility model completely simulates the rotation speed signal of the diesel engine, conforms to the coincided principle of the calibration and the use, and has the advantages of accurate calibration and simple operation.
Description
The utility model relates to the measurement instrument that is used to detect with adjustment diesel motor comprehensive parameter tester.
The diesel motor comprehensive parameter tester is under the situation that engine does not disintegrate, and by its multiple parameter detecting being carried out one and instrument of performance evaluation and fault diagnosis, in order to ensure its accuracy, must regularly carry out measurement verification to it.Owing to lack corresponding metering and measuring equipment in the prior art, make the staking-out work of diesel motor comprehensive parameter tester be difficult to carry out, manufacturer and metrological service rely on electronic device with in the signal direct input circuit or rely on motor car engine as factory inspection test or measurement verification means.The method of this direct input electrical signal has got around the measurement of sensor, has run counter to calibrating and has used corresponding to principle.And engine is the source that various parameters constantly change, and it also is inappropriate coming the calibrating instrument parameter as standard.
The purpose of this utility model is: a kind of diesel motor comprehensive parameter tester marking apparatus is provided, and energy is the tach signal of simulated engine fully, and meets calibrating and use one principle mutually, and it is accurate, simple to operate to demarcate.
The technical solution of the utility model is: a kind of diesel motor comprehensive parameter tester marking apparatus is characterized in that: comprise buncher, shaft coupling rotating disk, injection pump, high-pressure oil pipe, atomizer, petroleum pipeline, survey sensor and display; Be connected by shaft joint between the front end of the front side of the output terminal of described buncher and shaft coupling rotating disk, the rear side of shaft coupling rotating disk and injection pump; Described injection pump, high-pressure oil pipe, atomizer, fuel tank and petroleum pipeline join end to end and form a loop; Described survey sensor is clipped on the outer wall of high-pressure oil pipe, and described display is connected with sensor by lead.
Above-mentioned marking apparatus, its injection pump, high-pressure oil pipe, atomizer and petroleum pipeline have constituted the injection system of diesel motor together.By regulating the buncher of this marking apparatus, can make motor be in different rotating speed states, because the effect of shaft joint, the axle center of rotating disk and injection pump is rotation synchronously also, the rotation in injection pump axle center has driven the to-and-fro movement of its internal piston, produce oil spout, therefore will in oil pipe, produce the fuel injection signal of pulse feature, this signal is sampled and handle the tachometer value that just can obtain diesel motor by the sensor that is installed in the high-pressure oil pipe outer wall.On the one hand, marking apparatus shows as standard signal tach signal on display; On the other hand, utilize the engine comprehensive parameter tester to measure the tachometer value of synchronization, by relatively just obtaining the tachometric survey error of indication of diesel motor comprehensive parameter tester.When using this marking apparatus to demarcate rotary speed of diesel engine, the speed probe of engine comprehensive parameter tester can be installed on the relevant position of marking apparatus and do as a whole the demarcation, this just meets calibrating fully and uses corresponding to principle, thereby has guaranteed the accuracy of demarcating.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the front view of an exemplary embodiments of the utility model marking apparatus;
Fig. 2 is the vertical view of marking apparatus shown in Figure 1.
Diesel motor comprehensive parameter tester marking apparatus as depicted in figs. 1 and 2 comprises buncher 3, shaft coupling rotating disk 4, injection pump 5, high-pressure oil pipe 7, atomizer 8, petroleum pipeline 12, survey sensor 6 and display 11; Be connected by shaft joint between the front end of the front side of the output terminal of described buncher 3 and shaft coupling rotating disk 4, the rear side of shaft coupling rotating disk 4 and injection pump 5; Described injection pump 5, high-pressure oil pipe 7, atomizer 8, fuel tank 9 and petroleum pipeline 12 join end to end and form a loop; Described survey sensor 6 is clipped on the outer wall of high-pressure oil pipe 7, and described display 11 is connected with sensor 6 by lead.
In the present embodiment, buncher 3 is furnished with speed regulator 2, connects by lead between the two.
1 expression support among the figure, all parts all directly or indirectly are fixed on the support.
Shaft coupling rotating disk 4 in the present embodiment is the dishes of tracing to the source as the diesel engine speed signal.
