According to the utility model, synchronous measurement on the polished rod load and the reducer casing torque is realized, and inconvenience caused by wiring is avoided.
Description
Technical field:
The utility model relates to the measurement mechanism used on oil pumper, what be specifically related to is oil pumping machine polished rod load and reducer casing moment of torsion synchrometer.
Background technology
Measuring at present crank of reduction box of oil pumping unit axle moment of torsion method commonly used is to adopt electric measurement technique of strain gage, forms strain bridge on crank axle, to strain bridge, provides power supply can record the electric signal that this elastic shaft is turned round.After this strain signal is amplified, through overvoltage/frequency conversion, become the frequency signal be directly proportional to twisting strain.Paste foil gauge on crank axle, due to the narrow space between reducer casing and crank, greasy dirt is arranged on crank axle, so foil gauge and launch-box are not easy to be fixed on crank axle.Foil gauge is the loosening measurement effect that affects because of crankshaft rotation usually, and even foil gauge comes off and causes measuring termination.And, the test oil pumping machine polished rod load separates independently always and carries out with test reducer casing crankshaft torque, cause measured polished rod load and measured crankshaft torque asynchronous in time, this has proposed real problem to monitoring oil pumper running status.
Summary of the invention:
The purpose of this utility model is to provide oil pumping machine polished rod load and reducer casing moment of torsion synchrometer, and it measures for solving current employing electric measurement technique of strain gage the problem that crank of reduction box of oil pumping unit axle torque measurement effect is bad and can not synchronously carry out.
The utility model solves the technical scheme that its technical matters adopts: this oil pumping machine polished rod load and reducer casing moment of torsion synchrometer comprise obliquity sensor, load transducer, data acquisition unit, computing machine, obliquity sensor is arranged on reducer casing crank or connecting rod, load transducer is arranged on polished rod, obliquity sensor is connected by wireless signal transmission with data acquisition unit, load transducer is connected by wireless signal transmission with data acquisition unit, and data acquisition unit connects computing machine.
In such scheme, obliquity sensor is the obliquity sensor with magnetic stand, and obliquity sensor can be inhaled on crank or connecting rod easily.
In such scheme, load transducer adopts the buckle-type load transducer, and the buckle-type load transducer can be stuck on polished rod easily.
The utlity model has following beneficial effect:
The utility model has realized that oil pumping machine polished rod load and reducer casing crankshaft torque measure simultaneously, between obliquity sensor and load transducer and data acquisition unit, adopts wireless transmission, the inconvenience of having avoided wiring to bring.And obliquity sensor and load transducer easy for installation, handling safety.
The accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is fundamental diagram of the present utility model.
1 obliquity sensor 2 load transducer 3 data acquisition unit 4 computing machine 5 crank 6 connecting rod 7 polished rods.
Embodiment:
Below in conjunction with accompanying drawing, the utility model is described further:
As shown in Figure 1, this oil pumping machine polished rod load and reducer casing moment of torsion synchrometer comprise obliquity sensor 1, load transducer 2, data acquisition unit 3, computing machine 4, adopt buckle-type load transducer 2 and with the obliquity sensor 1 of magnetic stand.Buckle-type load sensor with polish rod 2 can be stuck on polished rod 7 easily, and obliquity sensor 1 can be inhaled easily on crank 5 or connecting rod 6, and the measurement range of obliquity sensor 1 is
Obliquity sensor 1 is connected by wireless signal transmission with data acquisition unit 3, load transducer 2 is connected by wireless signal transmission with data acquisition unit 3, adopt wireless transmission between obliquity sensor 1 and data acquisition unit 3, adopt wireless transmission between load transducer 2 and data acquisition unit 3, data acquisition unit 3 connects computing machine 4.
Shown in Fig. 2, in the utility model, data acquisition unit 3 receives the crank angle (or connecting rod inclination angle) of obliquity sensor 1 measurement and the oil pumping machine polished rod load that load transducer 2 is measured in real time, and the data that collect are saved in to computing machine, computing machine 4 calculates the relation of suspension point displacement and crank angle according to oil pumper model, physical dimension, in conjunction with polished rod load, draws suspension point power load-position diagram; Obtain crank of reduction box of oil pumping unit axle polished rod moment of torsion in conjunction with crank angle (or connecting rod inclination angle) and Pumping Unit calculation of parameter, then calculate the clean moment of torsion of crank axle according to counterbalance weight weight and equilibrium position.All adopt wireless transmission between obliquity sensor 1 and load transducer 2 and data acquisition unit 3, realize pumping unit hanging point power load-position diagram and oil pumping machine crank axle moment of torsion synchronism detection.
