Summary of the invention:
The present invention is the deficiency that overcomes prior art; A kind of secondary balancing times journey oil pumper is provided; Its active balance the power in up-down stroke, exported of motor; Improve the application life of motor and oil rig, guaranteed the uniformity of crank rotary speed, guaranteed the operate as normal of sucker rod and oil well pump.
The objective of the invention is to realize in the following manner: this secondary balancing times journey oil pumper; Comprise support, cylinder, sucker rod, oil pumping rope, motor and reducer; Support, motor and reducer are on the pedestal, and cylinder is located on the support, it is characterized in that: said motor connection reducer; The output shaft of reducer links to each other with the balance power transmission shaft through shaft coupling; Described balance power transmission shaft connects big balance weight, and the balance power transmission shaft is connected with driven shaft through transmission mechanism, and driven shaft is provided with little balance weight.
Preferably, described driven shaft is in the top of output shaft.
Preferably, described transmission mechanism is made up of driving wheel, driven pulley and driving-chain, and driving wheel is on the balance power transmission shaft, and driven pulley is located on the driven shaft, and driving wheel is in transmission connection through driving-chain and driven pulley.
Preferably, described driven shaft, little balance weight and transmission mechanism are in the casing.
Preferably, an end of described oil pumping rope is fixed on the casing, and the other end is walked around pulley and the cylinder of support upper end on the big balance weight successively, passes through polished rod eye again and links to each other with sucker rod.
Preferably, the top of described polished rod eye is provided with directive wheel, and the oil pumping rope is walked around directive wheel after polished rod eye links to each other with sucker rod, and directive wheel is fixed on the brace summer, and brace summer is obliquely installed on support.
The invention has the beneficial effects as follows, this secondary balancing times journey oil pumper, the output work of motor takes the lead in after big balance weight carries out once balance; Pass to little balance weight by driving-chain again and carry out secondary balancing, little balance weight is further regulated torque curve, eliminates negative torque; And further reduce peak torque, active balance the power in up-down stroke, exported of motor, the application life of having improved motor and oil rig; Guarantee the uniformity of crank rotary speed, guarantee the operate as normal of sucker rod and oil well pump, its reasonable in design; Guarantee normally carrying out of oil extraction operation, improved oil recovery efficiency.
