Product Explanation:This kind of pumping unit is based on the conventional pumping unit. The technique innovation is applied on the four-bar linkage. The back of the walking beam had a special curve shape, and flexible connection method between walking-beam and equalizer is used. So the length of the back of the walking-beam and the pitman arm will be changed according to the variational rotational angle of the crank.
This structure affects the changing principle of the torque factor and improves the balancing effect,thus energy is saved (compared with conventional ones, it can save energy about 25%).
