Abstract
The invention provides an integrated axial force and torque sensor for polished rods of a rod-pumped well. The integrated axial force and torque sensor has a strain body; strain gauges are attached to the surface of the strain body and connected with a circuit board; the strain body is cylinder-shaped and open at two ends, and provided with external threads or internal threads at two end parts; and the strain gauges include axial force strain gauges and torque strain gauges. The external threads or the internal threads at the two end parts of the strain body are connected with one ends of two sections of polished rods respectively to enable the strain body and the two sections of polished rods to form an integral polished rod of the rod-pumped well. During operation of the polished rod of the rod-pumped well, the axial force and the torque of the polished rod can be measured through the strain body, the strain gauges on the strain body as well as the circuit board. The integrated axial force and torque sensor has the advantages of simple and reasonable structure, convenience in installation, high test precision, and capability of reducing the test cost.
Description
Technical field
The present invention relates to the sensor of axial force and moment of torsion, especially a kind of for the axial force on polished rod of pumping well and torque sensor.
Background technology
For realizing, the operating mode of rod-pumped well is monitored, protected and controls, the axial force that need to bear at work polished rod of pumping well (pulling force, pressure) and moment of torsion are measured.In prior art, measuring axial force and the moment of torsion of polished rod of pumping well realizes by axial force transducer and torque sensor respectively, existing polished rod of pumping well axial force transducer is to realize the installation on polished rod by being combined with poliched rod eye, and existing polished rod of pumping well torque sensor is the installation realizing on polished rod by coordinating with web member.Above-mentioned axial force transducer and the torque sensor deficiency that situation independent, that install respectively exists is separately: 1, loaded down with trivial details, debugging trouble is installed; 2, the globality effect of sensor and polished rod is not good enough, and measuring accuracy is not ideal enough; 3, two kinds of sensors need be equipped with simultaneously, and expense is higher.
Summary of the invention
The object of the present invention is to provide a kind of integral pumping unit well polished rod axial force and torque sensor, this sensor can be connected as a single entity with polished rod of pumping well, and integrates the performance of axial force and torque measurement.
For achieving the above object, the present invention adopts following scheme: integral pumping unit well polished rod axial force and torque sensor, it has response body, on the surface of response body, be pasted with strainometer, strainometer is connected with circuit board, response body is the cylindrical shape of open at both ends, and the both ends of response body have external thread or internal thread, and two kinds of axial force strainometer and moment of torsion strainometers are counted in strain.
From such scheme, the external thread at response body both ends or internal thread are connected with one end of two sections of polished rods respectively, make response body and two sections of polished rods form holistic polished rod of pumping well, polished rod of pumping well at work, by response body and on strainometer and circuit board, can measure axial force and the moment of torsion of this polished rod.
The present invention is simple and reasonable for structure, and it is easy for installation, measuring accuracy is high, and can reduce testing cost.
