Abstract
The utility model provides a beam -pumping unit improves control circuit of oil -well pump coefficient of fullness, relates to oil field oil recovery technical field, and in particular to improves the beam -pumping unit control technique of oil -well pump coefficient of fullness. Connect a set of brake resistance between the PB of converter end and P+ end, its characterized in that the converter + connect a set of lower limit proximity switch between 24V end and the DI1 end, lower limit proximity switch is connected with first relay, the converter + 24V holds and DI2 hold between a set of upper limit proximity switch of connection, upper limit proximity switch is connected with the second relay. Through the utility model discloses an upstroke of beam -pumping unit and the horse head of down stroke go upward can be adjusted respectively with descending speed, and between two sections friction speeds of horse head, the rotational speed of motor is steady excessive simultaneously. The down speed of oil -well pump plunger increases the oil -well pump plunger speed of going upward, can obviously improve the coefficient of fullness of oil -well pump to improve the pump efficiency, reach the oil recovery cost is reduced the mesh.
Description
Technical field
This utility model relates to oil extraction in oil field technical field, controls technology particularly to the beam pumping unit improving oil well pump coefficient of fullness.
Background technology
During existing oil field produces, the general single inverter used controls a pumping-unit motor job.
Owing to oil-well pump of oil well is generally adopted by tubing pump, mainly it is made up of pump barrel and plunger, wherein in oil well pump work process, its coefficient of fullness is the important indicator weighing its pump efficiency, the downstream rate of oil pumper plunger is the lowest (beam-pumping unit jig frequency is the lowest, and its oil pump plunger piston downstream rate is the lowest), and its coefficient of fullness is the highest, but in order to not affect oil well output in actual production, the jig frequency of oil pumper can not arbitrarily be turned down.
When motor speed is constant, the jig frequency of oil pumper refers to that the caput Equi Asini of oil pumper completes the number of times of a periodic movement within the unit interval, and motor speed is the highest, and beam-pumping unit jig frequency is the biggest.
In the up-down stroke of existing oil pumper, the rotating speed of motor is identical, the velocity magnitude that pumping unit horsehead is up Yu descending can not be adjusted respectively, i.e. can not adjust pumping unit horsehead up (oil pump plunger piston is up) or the speed of descending (oil pump plunger piston is descending) respectively.
Utility model content
This utility model purpose is the control circuit proposing a kind of a kind of beam pumping unit motor that can improve pumping efficiency of oil pump.
This utility model includes the driving motor that converter is connected with converter, one group of braking resistor is connected between the PB end and P+ end of converter, it is characterized in that connecting a class lower limit proximity switch between the+24V end and DI1 end of converter, lower limit proximity switch and the first relay connect, between+24V the end and DI2 end of converter, connect a class upper limit proximity switch, upper limit proximity switch and the second relay connect.
During use, on the fixing seat outside the change speed gear box of beam pumping unit, it is respectively provided with upper and lower limit proximity switch relative to the upper and lower limit position of balance weight, balance weight is installed a Magnet.There is multi-channel control unit inside converter, the most as required, the operating frequency of motor can be set respectively.When the Magnet of balance weight is close to lower limit proximity switch, triggering the first relay conducting, converter just works with a certain frequency；When the Magnet of balance weight is close to upper limit proximity switch, triggering the second relay conducting, converter just works with another frequency.
The speed being achieved the upstroke of oil pumper and the caput Equi Asini uplink and downlink of down stroke by this utility model can be regulated respectively, and simultaneously between two sections of friction speeds of caput Equi Asini, the rotating speed of motor is the most excessive.Reduce oil pump plunger piston downstream rate, increase oil pump plunger piston speed uplink (i.e. the time of oil pumper down stroke is more than the time of upstroke), the coefficient of fullness of oil well pump can be significantly improved, thus improve pump efficiency, reduce the purpose of cost for oil production.
It addition, this utility model also connects buzzer between the+24V end and BO1 end of converter.Its objective is the oil pumper periphery personnel that will work for prompting, make personnel on the scene dodge in time.
