motor delivers high-speed rotating motion into the reducer through the
transmission belt. After the three-axis two-level reduction, the crank-link
mechanism changes the rotating motion to the beam's reciprocating motion.
The beam hanger which is hung on the horse head drives the oil well pump plunger to do reciprocating motion through the sucker rod to deliver downhole oil to the ground.
2.The Energy-saving Technology of Pumping Unit
Main Categories of Energy-saving Technology of Pumping Unit
frequency conversion speed control. We
can set our pumping unit free from the long-term inefficient condition.
③.After that, we can match the way the pumping unit work in with the oil well actual load to reduce electricity costs, reduce maintenance costs and improve operational efficiency.
Inverter we need should be in a higher size than the motor. The pumping unit is
far away from the power supply room, and sometimes there will be 1 km between
them. The loss on the line makes the voltage of inverter input lower, and the
⑤.Also, when we design the outlay motor, we have made it power a little smaller consider of it's batch-type load. That means, when we need a motor of 22kW,we should the 18.5 one. And so ,we need the power of Inverter a little bigger.
starting process of the frequency conversion control is soft start. And there
will be small starting circuits ,small power grids, and reduced energy
start reduce mechanical impact
starting can reduce the impact of the motor, gearbox, crank connecting rod,
etc., and it can also extend the life of the associated equipment
power factor of motor can be increased from 0.2~0.5 to 0.9, and we can reduce
the burden on the power grid and the transformer, reduce line losses, and we
can also get a significant reduction in the reactive loss.
the technical requirements, improve production efficiency
automaticly identify the up or down process,
it can change the speed of up or down process of pumping unit and solve the
stop working problems caused by changing the belt pulley。So
it can effectively improve production efficiency.
