Abstract
An automatic speed regulating gear of oil extractor comprises an upper dead point sensor, a lower dead point sensor, a control unit and a speed regulating unit. The upper dead point sensor and the lower dead point sensor are respectively connected to the control unit which is connected to the speed regulating unit; the speed regulating unit is connected to the motor of the oil extractor. The upper dead point sensor is disposed at an upper dead point of the oil extractor; the lower dead point sensor is disposed at a lower dead point of the oil extractor. The speed regulating unit is a frequency converter or an electromagnetic speed regulating device. Compared with the prior art, the automatic speed regulating gear of oil extractor of the utility model has the advantages of simple structure, convenient use and low cost; especially being used in low producing well or heavy oil well, the automatic speed regulating gear of oil extractor has the advantages of energy conservation and consumption reduction.
Description
One, technical field
The utility model relates to oil-field oil pumper automatic control technology field, is specifically related to a kind of oil pumper automation speed regulating device.
Two, background technology
At present, the speed regulating device of used for oil-field oil pumper can only be adjusted oil pumper jig frequency number of times, can not independently adjust the jig frequency number of times or the time of upper and lower stroke.This working method is unfavorable for saving energy and reduce the cost, and when especially using on stripper well or heavy oil wells, its defective is more outstanding.
Three, utility model content
The purpose of this utility model is exactly the defective that exists at prior art, and a kind of oil pumper automation speed regulating device that help saving energy and reduce the cost are provided.
Its technical scheme is: comprise TDCS TDC Sensor, lower dead center transducer, control unit and speed governing unit.Described TDCS TDC Sensor is connected with control unit respectively with the lower dead center transducer, and control unit is connected with the speed governing unit, and the speed governing unit is connected with pumping-unit motor.
Wherein, described TDCS TDC Sensor is installed in the oil pumper top dead center position; Described lower dead center transducer is installed in the oil pumper bottom dead center position.Described speed governing unit is frequency converter or electromagnetic speed regulating device.
The utility model has simple in structurely, easy to use, with low cost compared with prior art, uses on stripper well or heavy oil wells especially, has good energy-saving and cost-reducing advantage.
Four, description of drawings
Accompanying drawing is the circuit block diagram of a kind of embodiment of the utility model.
Five, embodiment
With reference to accompanying drawing, a kind of oil pumper automation speed regulating device comprise TDCS TDC Sensor 1, lower dead center transducer 2, control unit 3 and speed governing unit 4.Described TDCS TDC Sensor 1 is connected with control unit 3 respectively with lower dead center transducer 2, and control unit 3 is connected with speed governing unit 4, and speed governing unit 4 is connected with pumping-unit motor 5.Wherein, described TDCS TDC Sensor 1 is installed in the oil pumper top dead center position; Described lower dead center transducer 2 is installed in the oil pumper bottom dead center position.Described speed governing unit 4 is frequency converter or electromagnetic speed regulating device.
During operation, when oil pumper moves to top dead center position, 1 pair of control unit 3 of TDCS TDC Sensor sends the top dead centre signal, the prompting oil pumper will be soon descending, this moment, control unit 3 provided descending operation control to speed governing unit 4, and speed governing unit 4 control pumping-unit motors are installed the downstream rate operation of setting then; When oil pumper moves to bottom dead center position, 2 pairs of control units 3 of lower dead center transducer send the lower dead center signal, the prompting oil pumper will be soon up, and this moment, control unit 3 provided up operation control to speed governing unit 4, and speed governing unit 4 control pumping-unit motors are installed the speed uplink operation of setting then.Above-mentioned principle is arranged as can be seen, this device can independently be adjusted the jig frequency number of times or the running time of upper and lower stroke.It is applied on stripper well or the heavy oil wells, and energy-saving effect is particularly outstanding.
