The Research On Combination Of Parallel Mechanism For Floating Frame Oil Pumping

In the last century, pumping equipment has developed greatly in the globe. Various types of new model oil pumping has been researched and developed in the latest 20 years, the reliability and adaptability improved a lot, promoted the capability of oil pumping in the meantime deduced the load and changeable region of the oil pumping. The result is the improvement of the efficiency and the decrease of power consumption, while the balance effect and running, power, balance character has been improved dramatically.The general level of oil equipment has been improved a lot in china nowadays. But as the oil resource more complicated, its depth deeper, the rack that holding the pump enhanced, the moisture in the oil increased a lot gradually, it demand the oil pumping technology as follows: to improve the balance effect of oil pumping to save energy and life expectancy; to solve the great energy comsumption, especially at the down step when the energy reverse flow because of the stake of pumping drop itself, so the motor on the state of generator running.This paper gives a new way for oil pumping matching, analyze in detail in theory .Bypass estate the mechanism's suspend point slide,velocity,accelerate 's formula and torque of brace, with chart, to compare with different phase float frame pumping and the regular ones. It is obvious that the mechanism's suspend point slide, velocity, accelerate and non -coefficient figuree, v, a's changing discipline, reacted as a better character of running. When you look at the brace shaft torque, it eliminates minus torque, reduce the peak value of net torque and the capacity of the motor, cost, etc. it improved the general status of oil pumping.Above all, it is a new way as matching, has solved the problem of motor changed into generator, so realize the energy transmit positively to use the energy source. It will have a great market in the nearest future.
