Description
Technical field
The present invention relates to the pick-up unit of a kind of moment of torsion, load, rotating speed, related in particular to the integrated radio detector of screw pump pumping unit well load, moment of torsion and rotating speed.
Background technology
Ground driving screw pump is a kind of novel oil recovery machiner, has the following advantages: 1. pair oil well liquid wide accommodation; 2. there is not gas lock; 3. pump efficiency is high; 4. delivery rate is even, is easy to regulate; 5. adapt to discharge capacity scope large; 6. simple and convenient cost is low.It is a kind of very promising oil production equipment.
At present in the time detecting the operating mode of screw pump pumping unit well, need to combine just and can detect by several parts of load transducer, torque sensor, speed probe and signal gathering unit, there are the modules such as battery, wiring board, memory board collector inside, and load, torque and rotation speed sensor are fixed on spiral shell mark pump rod-pumped well for a long time.In testing process; need first screw pump well on the beam to be shut down; then collector is installed, and the sensors such as the signal wire of collector and load, moment of torsion, rotating speed are connected, and then start running screw-pump oil extractor detects; in testing process, collector stores detection data; after detection completes, also need to stop for the second time screw-pump oil extractor, take off collector; and then screw oil pumping machine well open, then by the data of collector storage with computer communication playback.Therefore, detecting screw pump oil well need to stop well and just can complete for twice.The defect that above-mentioned existing detection method exists is: if oil well silt content is large, oil is thick or power frequency starting up moment of torsion is large, all may cause the faults such as screw pump pumping unit well bar is disconnected, pump leakage, pipe leakage, rod and tube partial-wear, belt slip, the excessive motor damage of electric motor starting electric current, oilfield enterprise is caused to direct economic loss; Whole testing process is loaded down with trivial details, and the data collection time is also confined to manually go up well and detects, and workload is large, and detection data can not reflect etc. in real time, has limited the oil production technology analytical work of screw pump pumping unit well.
In addition three kinds of sensors of moment of torsion, load, rotating speed that traditional screw pump pumping unit well uses are independent separately, can not be contained in on-line measurement on polished rod of screw pump simultaneously; Some sensor bulk are larger, and signals collecting segment set degree of one-tenth is low, complex structure, install loaded down with trivial details, poor reliability while running up.
For " CN102141454A " discloses, a kind of name is called " detected transmission method and the device of screw pump pumping unit well moment of torsion, load, rotating speed " to China Patent Publication No.: a kind of detected transmission method of screw pump pumping unit well moment of torsion, load, rotating speed, in service at screw pump pumping unit well, gather moment of torsion, load, the rotary speed parameter of screw pump pumping unit well polished rod, moment of torsion, load, rotary speed parameter are carried out carrying out data calculation process after signal condition, then by the data storing through data operation or carry out wireless transmission.The device of realizing the method is: on a housing, be equipped with and in solar energy collecting plate, torque load sensor, speed probe and wireless transmission antenna housing, be provided with accumulator, power regulator module, signal condition module, data operation processing module, memory module, radio receiving transmitting module.The method can be monitored the working order of screw pump well on the beam in real time, has guaranteed the accuracy rate of diagnosis; The device providing can be realized under the condition not shutting down, without human intervention, and the moment of torsion to screw pump, load, rotating speed detect, and has guaranteed the security, reliability, the real-time that detect.
A difficult problem to screw pump pumping unit well load, moment of torsion, rotating speed, measurement at present.Although above-mentioned patented claim all focuses on load, moment of torsion and rotating speed in a device, but its wireless transmission antenna and speed probe are all assemblied in the outside of housing, because screw pump pumping unit well is in the time working, the rotating speed of polished rod is very fast, and this device is to be set on polished rod to carry out work, therefore the rotating speed of this device is also very fast, and the wireless transmission antenna and the speed probe that are assemblied in hull outside are easy to be thrown out of, cause device cisco unity malfunction, serviceable life is short.
