For the energy-saving effect to the employed energy-efficient equipment of pumping unit of well (energy-saving electric machine, energy-conservation power distribution cabinet etc.) all-sidedly and accurately carries out Comprehensive Assessment, detect relevant parameters, calculate and systematic analysis doing.Wherein, the test of the torque parameter of pumping-unit motor is an important content.In the prior art, be used for the electronic sensor of torsion-testing, by the elastic body of a steel axle shape, be attached to the strain gauge bridge on the elastic body, with become the treatment circuit that gives this electric bridge output signal and the lead that links to each other with display composition.Sensor is installed on the specific device, and during test, elastic body is turned round the resistance that makes a variation of strain gauge bridge generation on it, and this signal becomes standard value by treatment circuit, links display in wired mode then and shows.
The present test of domestic electric machine moment of torsion normally under lab or in specialized factory is finished, and it and on-the-spot actual condition differ greatly, and have directly influenced its result's accuracy.For addressing this problem, the dynamic twin axle torque sensor that the applicant once selected for use domestic specialized factory to produce has designed a cover torsion-testing apparatus, and it is used for on-the-spot test.Find that in use the torque sensor that is disposed in this device has following subject matter:
1. this torque sensor has strict requirement to radial force, need be fixed with bearing seat between shaft coupling and belt pulley.This makes whole testing device volume excessive (4 meters long, and 1 meter wide), and weight is very heavy.
2. can not long time continuous working because of the twin axle sensor that adopted, in order not influence production, do not damage sensor again, test finishes also to be needed sensor is taken off.Like this, each test must adorn, be torn twice open, and installs and removes at every turn, all needs four-player half a day consuming time, and efficient is extremely low.
Summary of the invention:
The purpose of this utility model is to make torque sensor can be used for on-the-spot test, and does not need the servicing unit of high precision large volume cooperate to install, and adorns, tears open simple, and on-line testing can be carried out easily and efficiently.
The torque sensor of realizing above-mentioned purpose is designed to belt wheel shape wireless type, and the steel elastic body that is about to post strain gauge bridge is made the shape of belt pulley, connects a transmitter module behind the signal transmitting treatment circuit, is that treatment circuit is powered with chargeable battery.Concrete structure is, elastomeric end face in the belt wheel shape is left annular groove, strain gauge bridge sticks on the wall of annular groove, signal transmitting treatment circuit plate, transmitter module, rechargeable battery are embedded in the annular groove, strain gauge bridge, transmitter module, rechargeable battery link to each other by the relevant interface of lead with signal transmitting treatment circuit plate, signal transmitting treatment circuit plate and transmitter module are locked in the annular groove by silica gel, load onto end cap on the annular groove, the switch of control battery is installed on the end cap that links with elastic body, and the fast antenna of emission mould passes end cap and stretches in the air.
Take off the belt pulley on the pumping-unit motor at the scene, sensor of the present utility model is resembled installation belt pulley sample to install on the motor shaft, and link with gear train, start motor, when the elastic body of belt wheel shape is subjected to moment of torsion and after producing microdeformation, deformation takes place in the strain gauge bridge that sticks on this elastic body thereupon, produce change in resistance, AC signal to a variation of signal transmitting treatment circuit plate output, handle through this circuit, the outputting standard signal, by transmitter module through its antenna transmission, by receiving trap, promptly obtain the torque parameter of motor.So just finished the on-the-spot test of energy-saving electric machine torque parameter.
The beneficial effect that the utility model is compared with prior art had is:
1. be contained in the form of belt pulley and be subjected to directly to bear at the scene on the measured motor load, the gained result directly, true, realized the online dynamic-torque test.
2. the whole parts of sensor are installed on the belt pulley, and compact conformation, volume are little, adorn, tear open simple, have greatly reduced the auxiliary or additional work amount before and after the test, make the testing efficiency height.
3. being more conducive to test with wireless mode transmission test data than lead transmission form carries out in oil wells in field.
