Description

A kind of hydraulic dynamometer measures calibration system
Technical field:
It the utility model is related to a kind of measurement calibration system, and in particular to a kind of hydraulic dynamometer measures calibration system.
Background technology:
Hydraulic dynamometer is now widely used for a variety of original machine power testing fields, as prime mover load test Pay(useful) load, can measure the power output of prime mover, while coordinate prime mover to carry out various working point transformation experiment.At present, The mainly tested prime mover of the operation principle of hydraulic dynamometer drives dynamometer rotor to rotate, will under the stickiness power effect of water Moment of torsion is delivered to stator and housing, drives stator case component with respect to dynamometer outer bearing bearing small angle rotation, stator case This movement tendency of component is drawn(Pressure)The prevention of sensor cluster, and drawing is measured by sensor(Pressure)The size of power, then The power of prime mover can be obtained with reference to torque arm length and rotating speed.But as power-measuring device, in hydraulic dynamometer running In there may be measurement error or during power loss, therefore need to dynamometer measurement power and torque value enter rower Fixed and calibration.So it is very necessary to design a kind of hydraulic dynamometer measurement calibration system.
Utility model content:
The utility model is made up and improved in place of above-mentioned the deficiencies in the prior art, there is provided one kind is used for hydraulic dynamometer and inhaled The experimental rig that receipts power and torque condition are demarcated and calibrated, prime mover are operated in hydraulic dynamometer performance curve, are led to Measurement is crossed, the power and torque value that contrast prime mover input parameter value measures with hydraulic dynamometer, system is measured to hydraulic dynamometer System is demarcated and calibrated.It can promote and use on a large scale.
The technical solution adopted in the utility model is:A kind of hydraulic dynamometer measures calibration system, and the calibration system includes Motor, shaft coupling, torque sensor, support base, shaft coupling and hydraulic dynamometer, high-precision rotating speed is housed on motor Measuring instrument, the output end of motor are equipped with high-precision power measuring instrument, can measure the rotating speed and motor of motor respectively Power output, the output shaft of motor are connected by shaft coupling with hydraulic dynamometer, and torque sensor is housed on shaft coupling, are used With the output torque of measurement motor axle, when caliberating device works, start the performance curve that motor is operated in hydraulic dynamometer Interior operating point, working speed and power now are measured, read the moment of torsion of torque sensor measurement, and according to this numerical value to surveying Work(device revolution counter reads rotating speed and demarcated, and dynamometer pull pressure sensor is measured and drawn(Pressure)Power is demarcated.
The torque sensor is high-precision torque sensor.
The beneficial effects of the utility model:It is simple in construction, it is reasonable in design, it is proposed that a kind of hydraulic dynamometer measurement accuracy Calibration and calibration system, at present, system and equipment on the demarcation of hydraulic dynamometer measurement accuracy are there is no, is easy to push away on a large scale Wide and use.The dynamometer power demarcated as needed, moment of torsion and the range of speeds, from satisfactory prime mover as power Source, typically it is easy to control the parameters such as prime mover rotating speed, power, from high-precision power, turns as power source from motor Fast measuring apparatus, prime mover output parameter is measured, meanwhile, the shaft coupling between prime mover and dynamometer is designed, is being joined High-precision torductor is integrated on joint, for measuring prime mover reality output moment of torsion.
Brief description of the drawings:
Fig. 1 is structural representation of the present utility model.
Embodiment:
Reference picture 1, a kind of hydraulic dynamometer measure calibration system, and the calibration system includes motor 1, shaft coupling 2, turned round Square sensor 3, support base 4, shaft coupling 5 and hydraulic dynamometer 6, high-precision tachometer of measuring, driving electricity are housed on motor 1 The output end of machine 1 is equipped with high-precision power measuring instrument, can measure the rotating speed and output power of motor of motor 1 respectively, drives The output shaft of dynamic motor 1 is connected by shaft coupling 5 with hydraulic dynamometer 6, torque sensor 3 is housed, to measure on shaft coupling 5 The output torque of motor shaft, when caliberating device works, start the work that motor 1 is operated in the performance curve of hydraulic dynamometer Condition point, working speed and power now are measured, read the moment of torsion that torque sensor 3 measures, and according to this numerical value to dynamometer Revolution counter reads rotating speed and demarcated, and dynamometer pull pressure sensor is measured and drawn(Pressure)Power is demarcated.The torque sensing Device 3 is high-precision torque sensor.
