2. Special Pumping Unit Double Horse-head Walking Beam Pumping Unit The rear part of this unit is a changing radius arc connected to the equalizer beam by a flexible joint. This configuration eliminates the dead angle restriction, enlarges the walking beam pivot range, and increases the stroke by 20% to 70%. In working condition, the regular changing length of rear part makes the counterbalance moment increase and decrease along with load increasing and decreasing. This structure makes the whole unit with low fluctuation, good balanced state and reduces energy consumption by 30% to 60%. |  |

Phased Crank Counterbalance Pumping Unit The main difference between this pumping unit and the conventional pumping unit is that a phase angle between crank pin center line and counterbalance weight centerline causes the movement of crank shaft out of phase with the torque produced by load. This structure makes the net torque curve smooth, reduces the peak torque value, prolongs service life and reduces energy consumption. ● Models and Specifications of Phased Crank Counterbalance Pumping Units |  |

Bent Beam Pumping Unit The rear of the walking beam is a bent shape that provides more posts for adjusting beam balance as required. The balance movement of the walking beam varies as the horse-head moves up and down. The bent end of the walking beam modifies the crank balance curve, and the compound torque curve conforms to the load torque curve, smoothing out and reducing peaks in the net torque curve. This reduces the rated torque of the gear reducer and rated power of electric motor, putting structural parts under less stress and reducing power consumption by over 30%. ● Models and Specifications of Bent Beam Pumping Units |  |

Compound Balance Pumping Unit Compound balance pumping units are similar to conventional pumping units, but there is a balancing counterweight on the rear end of the beam to balance the load jointly with the crank balance. The working principle is also similar to that of conventional units, but the beam balance spreads out the peak load to improve the balancing effect and decrease stress on the bar members. |  |

Front-mounted Crank Balance Pumping Unit The construction of front mounted pumping units is quite different from that of conventional pumping units. The pitman, crank mechanism and horse-head are all mounted on the front side of the samson post bearing, and the balance counterweight and pitman are mounted on each end of the crank. These pumping units have the advantages of longer strokes and lower power use. |  |

Rare Earth Permanent Magnet Three Phase Synchronous Motor Permanent magnet synchronous motors with large starting torque can reduce energy consumption than asynchronous motors by 25%. A 37 kW synchronous motor can replace a 55 kW asynchronous motor. These motors can realize asynchronous starting and synchronous running. They have the same size of Y-series asynchronous motors. Stator construction is similar to that of asynchronous motors, and F grade insulation is used. The motor includes two parts: squirrel-cage and permanent magnet. ● Models and Specifications of Rare Earth Permanent Magnet 3-Phase Synchronous Motors Model
