Description
Technical field:
The utility model relates to a kind of balance of well pumping unit control device, especially beam-pumping unit balance control device.
Background technology:
During oil pumper work, walking beam has top dead centre and lower dead center, and ideal situation is that corresponding top dead centre electric current of motor and lower dead center electric current are to equate, and actual conditions are that two electric currents are unbalanced in the process of operation.In order to keep the running of this dynamic unbalance oil pumper, motor of oil extractor then needs to overcome and exceeds that part of gravity of dynamic equilibrium, so just cause motor to want overload operation, cause that the motor current sinking increases, cause motor, air switch, phenomenon such as disconnecting link switch etc. are overheated because of long-time overload operation produces, burn.Because dynamic equilibrium is destroyed, cause oil pumper bigger in the load variations that upper and lower stop bore, destroyed at the uniform velocity original design of running, cause each drive disk assembly of oil pumper all to be subjected to bigger impact, the reduction box internal gear is clashed into, the skidding of the coming off of the gear teeth, belt, burn, the becoming flexible, come off, the damage of tailing axle axis position bearing of kinematic link.
The utility model content: the technical problems to be solved in the utility model provides a kind of balance of well pumping unit control device, can realize the dynamic equilibrium of oil pumper effectively.Technical scheme: a kind of balance of well pumping unit control device, have walking beam, motor, it is characterized in that: walking beam is provided with counter weight device, also is provided with position sensor; The power line of motor is provided with current transformer, and current transformer connects the signal input part of single-chip microcomputer; The signal output part of position sensor connects single-chip microcomputer; The signal output part of single-chip microcomputer is succeeded electrical equipment, and wherein this relay is for controlling the relay of counter weight device servomotor switch.Beneficial effect: the utility model can immediately monitoring oil pumper balance and the oil pumper load between equilibrium state, can overcome fully oil pumper because of load variations all whole issues that cause, can eliminate fully because of the difference between current between the caused upper and lower stop of imbalance, make it approach zero, reach saves energy and can reduce the purpose of producing consumption.
