The pumping unit load sensor guarantees the test precision, assures the personal safety of operating staffs, and reduces the damage probability of the devices of the pumping unit well. As an embedded antitheft bolt is arranged in a spigot, the pumping unit load sensor has the characteristics of convenient installation and detachment, low installation and maintenance cost and strong antitheft ability, and reduces the stop time.
Description
Technical field
The utility model belongs to the auxiliary test unit of petroleum industry, and particularly a kind of oil pumper load sensor is used on the rod-pumped well, finishes the collection of load-position diagram data.
Background technology
The load-position diagram of rod-pumped well is the underground pump work state of reflection, judge the whether foundation of ordinary production of oil well, the admission load-position diagram is the important process content of oil well daily management, load sensor is finished the load value of gathering oil pumper, is the indispensable parts of admission load-position diagram.The cylindrical shape load sensor is generally adopted at the scene at present, the irony structure, and the elastic strain sheet is attached to the cylindrical shape wall.Use proof to have following defective by the scene that Haiti, beach district well, Rotaflex belt oil pumping machine well, height is contained sand, wax, heavy oil wells:
1, failure rate height: because humidity, the temperature variation of Haiti, beach district work under bad environment, especially air are big, salt air corrosion is serious etc., and the elastic strain sheet very easily damages and drifts about, and the data of admission often error are bigger.
2, be difficult for installation and removal: the cylindrical shape load sensor need be enclosed within on the polished rod, must unload the load of winning oil pumper during installation, and dismantle polished rod clamp and anti-raising one's hat.The part well is because corrosion seriously is difficult to dismounting, and two horse head oil pumper hair plait unloadings back is beaten easily and turned round, and is rolled into twisted shape, and Rotaflex belt oil pumping machine well load is heavier, and work space is again little, and these wells install wastes time and energy.
3, operation is dangerous: long 2 to 3 meters of part oil well polished rod, and 4 to 5 meters of the safe reference fields of distance are changed load sensor and are belonged to work high above the ground, have big potential safety hazard; Take off the polished rod clamp in the unloading process and also hurt ground cooperation personnel easily; The oil pumper of brake failure also causes personal injury easily.
4, maintenance cost height: the one, the polished rod clamp is played the shaky polished rod that makes easily and is come off, and causes the well of lying.The 2nd, fixedly the slips sheet of polished rod clamp is dismantled twice back and just must be changed, and the repeated disassembled and assembled of polished rod clamp makes polished rod be subjected to the influence of shearing force easily and damages.
5, influence oil well output: change load sensor and need stop the well unloading, will influence oil well output, it is just many more to stop the long more influence of well time.Even height contains sand, the content of wax or heavy crude well, stops the long more just easy more well of lying of well time.
Summary of the invention
The purpose of this utility model provides a kind of oil pumper load sensor, overcomes the defective on existing load sensor structure and the material, and convenient the use guarantees the precision of load-position diagram admission, for oil well production provides high-quality test data.
The purpose of this utility model is achieved in that a kind of oil pumper load sensor comprises elastic strain body and circuit module, the elastic strain body is connected with circuit module by signal transmssion line, housing of the present utility model is the U type, and the elastic strain body is vertically mounted on the both sides of U shell body.U shell body can directly be inserted on the poliched rod eye of rod-pumped well, and is easy to operate.
Compared with prior art the utlity model has following useful effect: this load sensor is a U shell body, has overcome the defective of existing product, and the mounting means of change of load sensor on rod-pumped well makes load sensor be convenient to installation and removal.Guarantee operating personnel's personal safety, the equipment of rod-pumped well has also reduced damage simultaneously.Adopt stainless steel material, 4 independently the elastic strain body embed housing, housing does not stress in application.4 elastic strain bodies are installed in the both sides of U shell body respectively, and stability under loading is even, make the operation of poliched rod eye keeping parallelism, have guaranteed measuring accuracy.Spigot is provided with built-in anti-theft bolt, the characteristics that have easy installation and removal, reduce the well time that stops, the installation and maintenance expense are low, anti-theft capability is strong.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment
Below in conjunction with embodiment the utility model is done further detailed description: a kind of oil pumper load sensor, comprise elastic strain body 2 and circuit module 4, elastic strain body 2 is connected with circuit module 4 by signal transmssion line, and elastic strain body 2 is vertically mounted on the both sides of U shell body 1.The housing of U shell body 1 socket both sides is provided with mounting hole, in shooting property response body 2, the degree of depth of mounting hole is less than the height of elastic strain body 2.Elastic strain body 2 comprises cylinder and pressure bearing head, and the top cylindrical of pressure bearing head is provided with chamfering, and curved structure is exposed to outside the U shell body 1.Four elastic strain bodies 2 are installed at least, the mounting hole interference fit of elastic strain body 2 and U shell body 1 on the U shell body 1.The top plan of pressure bearing head is parallel with U shell body 1, has good parallel fulcrum, and the whole high strength elastic steel that adopt are manufactured stable performance.Anti-theft bolt 3 is installed in the socket end of U shell body 1.Anti-theft bolt 3 comprises screw rod and swivel nut, and swivel nut is sleeved on the screw rod, and screw rod is loaded on the end of U shell body 1, and the length of swivel nut conforms to the width of U shell body 1 socket.The bolt hole outer end that U shell body 1 is installed anti-theft bolt 3 is provided with shrinkage pool, and the outer end of screw rod is many prismatic structure, as prismatic, four prismatics or irregular many prismatic structure.
During on-the-spot the use, the oil well of automatization controlling device has been installed, this load sensor can be installed in aboveground always, at any time the wireless transmission load-position diagram.During installation, a side that earlier signal transmssion line is fixed on a special use has on the fixation steel plate of semicircle opening, and oil pumper unloading then allows poliched rod eye and square clamp vacate installing space, fixation steel plate is hung on the polished rod again, inserts this sensor.At last fixing in the mounting hole of anti-theft bolt 3 insertion U shell bodies 1.Adjust the carrying position of this sensor, slowly releasing of brake makes load sensor and fixation steel plate be able to eat load again, connects signal transmssion line and starts oil pumper.The oil well that automatization controlling device is not installed need not install and fix the fixation steel plate that signal transmssion line is used, and when enrolling load-position diagram, can test as long as the collection main frame is worn the bolt-type signal transmssion line at every turn.
