1.CYJ Conventional Walking Beam Pumping Unit

Conventional walking beam pumping unit has the basic form of a beam pumping unit.which adopts a crank equilibrium beam unit with a crank angle of °, and features a simple structure, stable and reliable operation and other characteristics, it is applicable to oil extraction in all kinds of oil fields. It has been widely used across countries from the early days of the development of oil fields to the present day, but it is not efficient enough and quite energy.consuming.

2.CYJ Phased Walking Beam Pumping Unit

The phased walking beam pumping unit is designed based on the conventional pumping unit, and adopts a structure with a nonzero equilibrium angle and large crank angle between extreme positions. The crank is easy to cross the dead point and has good power transmission performance. The unit features a simple structure, stable and reliable operation, energy saving and easy operation and maintenance. It is suitable for the extraction of crude oil under various working conditions and has been widely used in different oil fields in China.

3.CYJS double horse-head walking beam pumping unit

The double horse-head walking beam pumping unit is a long stroke energy-saving pumping unit for the recovery of low viscosity crude oil and high water cut crude oil, and can also be used for the recovery of viscous crude oil. The unit's walking beam adopts the reducing arc-shaped rear arm, and the walking beam and the beam has a flexible soft connection structure between, which not only retains the characteristics of the conventional walking beam pumping units, but also features long stroke, small even fluctuation of the static torque acting on the reducer, reliable operation, energy saving, high efficiency, etc., making it well received by the oil field users.

4.CYJT walking beam pumping unit with controllable diameter and variable torque 

The pumping unit with controllable diameter and variable torque is optimized on the basis of conventional walking beam pumping units. It adopts a compound balance mode with a lengthened rear arm of the walking beam and a structure with size and position of balance adjustable so that its walking beam counterweight can basically be balanced with the oil well load, thus reducing the torque output of reducer and achieving particular remarkable energy saving performance. In addition to the performance of conventional beam pumping units, it also has the characteristics of smooth running, easy to start, economy of materials, and better comprehensive performance. The pumping unit is an energy-saving pumping unit with a common stroke and low stroke frequency, which is suitable for crude oil recovery under various working conditions.

5.CYJW curved walking beam pumping unit

The difference between the curved walking beam pumping unit and the pumping unit with variable diameter and torque is that the rear arm of the walking beam is not adjustable.

6.CYJP Downward Biased Barbell Beam-type Pumping Unit

On the basis of conventional pumping units, the downward biased barbell beam-type energy-saving pumping unit adopts a compound balance structure combining walking beam balance and crank balance in the form of a barbell installed at the rear end of the walking beam,.which meets the balance requirements of the pumping unit to the greatest extent. In addition to the characteristics of conventional pumping units, it has an obvious energy-saving performance and is suitable for crude oil recovery under various working conditions.
