Abstract
The utility model belongs to the measurement technology and relates to a tester for a combination instrument of an airplane motor. The tester comprises a power supply module, resistors and a precision potentiometer, wherein the power supply module is connected with one end of the first resistor; the other end of the resistor is connected with one end of the second resistor; the other end of the second resistor is connected with a cathode of the power supply module; one end of the premise potentiometer is connected with a connecting point of the second resistor; and the other end of the precision resistor is connected with the cathode of the power supply module. The utility model solves the difficulties in linearity degree, isolation degree, anti-jamming capability, calibration and the like when the discharge temperature of the airplane motor is simulated; and when the meter is detected by a worker, the external connection is simple and the operation is convenient. The utility model can save the expense for annual scheduled maintenance of a precision voltage-stabilizing power supply and a millivolt grade voltage regulator. The tester not only can be used for testing the overall performances of the combination instrument of the airplane motor, but also can be used for quickly positioning fault points of fault finished products, so that maintenance staff can conduct quick determination and repair.
Description
Technical field
The utility model belongs to measuring technique, relates to a kind of aircraft engine combination instrument exerciser.
Background technology
Aircraft engine combination instrument exerciser is that the delivery temperature, oil temperature, fuel pressure, main reducing gear oil temperature, lubricating oil pressure, hydraulic pressure, main reducing gear lubricating oil pressure and the current/voltage that are used for the simulated aircraft engine are isoparametric.Exerciser adopts engine parameters such as the exchanging of precision resistance signal, different range and ratio, d. c. voltage signal simulated exhaust temperature, oil temperature.At present, employed aircraft engine combination instrument exerciser is when the delivery temperature of simulated aircraft engine, need external accurate stabilized voltage supply (3V) and millivolt step voltage regulator to control input voltage, more complicated in practical operation, a plurality of links cause cumulative errors.
The content of invention
The purpose of this utility model is to propose a kind of aircraft engine combination instrument exerciser of external power supply and voltage regulator separately that need not again when the simulated aircraft engine exhaust temperature.Technical solution of the present utility model is, exerciser comprises power module, resistance and precision potentiometer, one end of power module and resistance joins, and an end of the other end of resistance and another resistance joins, and the other end of another resistance and the negative pole of power module join; One of precision potentiometer is terminated on the contact of resistance and another resistance, and the other end of precision potentiometer is connected to the negative pole of power module.Advantage that the utlity model has and beneficial effect, the utility model has solved the difficult points such as the linearity, isolation, antijamming capability and demarcation when the simulated aircraft engine exhaust temperature, the staff is when detecting combination instrument, and is outside the connection simply, easy and simple to handle.Can save the expense of accurate stabilized voltage supply and the annual fixed inspection of millivolt step voltage regulator.This exerciser can carry out all round properties test to the aircraft engine combination instrument on the one hand, avoids the directly installation of fault product, thereby improves the efficient and the quality of aircraft general assembly; Can locate rapidly the trouble spot of fault finished product on the other hand, make the maintainer judge fast and repair.
Description of drawings
Fig. 1 is the utility model structural representation..
Embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.Exerciser comprises power module 5, resistance R 2 and R3 and precision potentiometer P9,1 pin and 2 pin of power module 5 are connected to the 28V power supply, 3 pin and the resistance R 2 of power module 5 are joined, one end of the other end of resistance R 2 and another resistance R 3 joins, and No. 4 pin of the negative pole of the other end of another resistance R 3 and power module 5 join; One of precision potentiometer 2 is terminated on the contact of resistance R 2 and another resistance R 3, and the other end of precision potentiometer P9 is connected to the negative pole of power module.
Power module 5 is the power module of a 28VDC-5VDC, and power module 5 becomes 5 volts of DC voltage with 28 volts of DC voltage, obtains 2 volts of voltages by resistance R 2 and resistance R 3 dividing potential drops; Precision potentiometer P9 adopts the multi-turn precision potentiometer, and 2 volts voltages that this multi-turn precision potentiometer obtains after with dividing potential drop are handled, and simulating provides the aircraft engine delivery temperature required voltage signal.
