Abstract
The utility model discloses a broken rod automatic safety device is prevented to oil well, the load transducer, switch board and the auto -power -off protector that connect gradually including the passing signal line, the load transducer passes through the polished rod and links to each other with the beam -pumping unit, and the switch board passes through the cable with pumping -unit motor and links to each other. The utility model discloses with instantaneous load passing signal line transmission to the switch board that the beam -pumping unit moved the in -process, the switch board judges according to instantaneous load whether it surpasss the settlement scope, if instantaneous load exceedes when setting for the maximum value, start the power -off protection ware, let pumping -unit motor cut off the power supply in the twinkling of an eye, stop the beam -pumping unit and move, prevent that the beam -pumping unit from continuing the emergence that the operation leads to the phenomenon of beam hanger rupture in the pit, avoided the beam hanger fracture to lead to the oil well trouble to reach the damage to the oil production equipment, improved oil production equipment job stabilization nature.
Description
Technical field
The utility model belongs to oil recovery machiner equipment technical field, is specifically related to the anti-breaking bar automatic safety device of a kind of oil well.
Background technology
In each elephant in the whole nation, beam hanger fracture is one of common oil well failure.Beam hanger fracture not only causes this mouthful of oil well normally to adopt and takes out, and the workload of well workover process is huge, and each workover cost is quite high.Beam hanger major cause of failure is that beam hanger eccentric wear, holddown etc. cause down-hole instantaneous load, resistance excessive, thus the beam hanger that fractures in oil pump running process, cause oil well accident.
Utility model content
The purpose of this utility model is to provide the anti-breaking bar automatic safety device of a kind of oil well, solves the problem of existing beam hanger easy fracture, avoids the damage that oil well accident and disconnected pole pair pumping unit cause.
The technical scheme that the utility model adopts is, the anti-breaking bar automatic safety device of a kind of oil well, comprises the load transducer, switch board and the automatic break protecting that are connected successively by holding wire; Load transducer is connected with oil pumper by polished rod, and switch board is connected by cable with pumping-unit motor.
Feature of the present utility model is also,
For under measuring well moment the load transducer of peak load and polished rod affixed.
Automatic break protecting is arranged in switch board.
The beneficial effects of the utility model are, the anti-breaking bar automatic safety device of a kind of oil well, by being arranged on the load transducer of well head, instantaneous load in oil pumper running is transferred to switch board by holding wire, according to instantaneous load, switch board judges whether it exceeds setting range, if when instantaneous load exceedes setting maximum value, start power-off protector, allow pumping-unit motor instant cut-off, oil pumper is stopped to run, prevent oil pumper from continuing to run the generation causing down-hole beam hanger breakage phenomenon, avoid beam hanger fracture and cause oil well failure and the damage to oil production equipment, further increase safety during oil well operation.
Accompanying drawing explanation
Fig. 1 is the structural representation of the anti-breaking bar automatic safety device of a kind of oil well of the utility model.
In figure, 1. oil pumper, 2. polished rod, 3. load transducer, 4. switch board, 5. automatic break protecting, 6. pumping-unit motor.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
As shown in Figure 1, the anti-breaking bar automatic safety device of a kind of oil well, comprises the load transducer 3, switch board 4 and the automatic break protecting 5 that are connected successively by holding wire; Wherein, load transducer 3 under measuring well moment peak load, be connected with oil pumper 1 by polished rod 2; The load signal that switch board 4 can transmit according to load transducer 3 judges whether the peak load exceeding setting, and switch board 4 is connected by cable with pumping-unit motor 6; Affixed between load transducer 3 and polished rod 2; It is inner that automatic break protecting 5 is arranged on switch board 4.
Operating principle of the present utility model is, when certain model oil pumper is in running, there is the phenomenon such as holddown, beam hanger eccentric wear in down-hole, when causing well head load, resistance excessive, the instantaneous load of perception is transferred to switch board 4 by holding wire by load transducer 3, according to instantaneous load, switch board 4 judges whether it exceeds setting range.If instantaneous load exceedes setting maximum value, start power-off protector 5, allow pumping-unit motor 6 instant cut-off, stop oil pumper 1 to run, thus prevent oil pumper 1 from continuing to run the generation causing down-hole beam hanger breakage phenomenon.
