Description
Technical field
The utility model relates to a kind of stepless speed regulation AC servo motor dragging system, is specially adapted in the oil pumper servo-control system.
Background technology
Along with the prolongation of oilfield exploitation time, field output is constantly successively decreased, the phenomenon ubiquity of oil well liquid-supplying deficiency, and output fluctuation is bigger; Oil pumper adopts conventional y series motor to drag, owing to be subjected to the restriction of factors such as equipment, generally speaking, minimum jig frequency can only reach per minute 3 times, and on-the-spot adjustment workload is bigger, makes the oil well pump detection period shorten with this understanding, and power consumption is big, pipe, bar serious wear, production cost per tone oil is high.Therefore, how controlling under the prerequisite that does not influence oil well output and to reduce cost of winning, increase economic efficiency is the problem that the oil field generally is concerned about all the time.Nowadays most of oil pumper transfers the ginseng process all more loaded down with trivial details, wastes time and energy, and also needs constantly to change belt pulley if reduce jig frequency, has also increased cost simultaneously.The traditional oil pumper of China generally adopts magneto and two power motor.Magneto, two power motor can not be for a long time in vibration, impact, high low temperature, damp and hot etc. comparatively move under the rugged environment, exist torque capacity retrained by the permanent magnet degaussing, shock resistance is poor, high rotating speed is restricted, shortcomings such as the less and starting difficulty of power, and permanent magnet synchronous motor structure is than the asynchronous motor complexity, and cost is higher.Be in low load condition during operate as normal, and need high torque (HT) when starting, reduced its application life.
The utility model content
The purpose of this utility model provides a kind of stepless speed regulation AC servo motor dragging system, be applied in the oil pumper servo-control system, solve the following problem that exists in the existing oil pumping system: the oil well pump detection period is short, and power consumption is big, pipe, bar serious wear, production cost per tone oil is high; Servo-drive system and motor transfer the ginseng process loaded down with trivial details, waste time and energy; Motor can not be for a long time in vibration, impact, high low temperature, damp and hot etc. comparatively move under the rugged environment, exist torque capacity retrained by the permanent magnet degaussing, shock resistance is poor, high rotating speed is restricted, the less and starting difficulty of power; Be in low load condition during operate as normal, and need high torque (HT) when starting, reduced its application life.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of stepless speed regulation AC servo motor dragging system, mainly comprise incremental encoder, threephase asynchronous, SERVO CONTROL cabinet, null pick-up, load sensor, limit switch, the SERVO CONTROL cabinet connects incremental encoder, threephase asynchronous, null pick-up, load sensor and limit switch respectively; Incremental encoder is built in the threephase asynchronous, and null pick-up is connected on the sucker rod, and load sensor is connected on the sucker rod, and limit switch is connected on the upper brace.
The utility model has been realized oil pumper is carried out the online in real time intelligent control, economize on electricity, save cost, manpower man-hour, this utility model realizes that low power low rotation speed large torque servomotor replaces the high-power common electric machine on the former oil pumper simultaneously, add that the SERVO CONTROL cabinet of being furnished with realized the stepless time adjustment to oil pumper, soft the soft function of stopping again, help reducing the wearing and tearing of oil pumper parts, reduce the wearing and tearing and the vibration of oil pumper, reduce the packing leakage of oil, prolong the application life of oil pumper, improved the utilization rate of equipment; And threephase asynchronous is compared the cost performance height of permanent magnetism, two power motors; Than frequency converter timing, this servo-drive system does not have harmonic pollution; Perfect monitoring, defencive function; The servo driving cabinet have overvoltage, overcurrent, short circuit, phase shortage, overload, etc. defencive function, can realize that various parameters show, the handled easily personnel understand the oil well working condition, guarantee the safe operation of oil well, the intellectuality of the management that realizes recovering the oil; The hidden danger of not demagnetizing, long service life, easy to maintenance.
