Tower mechanical reversing vertical belt pumping unit

Tower type mechanical reversing (belt) vertical pumping unit is a vertical pumping unit with chain closed-loop drive and belt traction.

This series of vertical belt pumping unit has the advantages of long stroke, adjustable stroke, simple operation, convenient transportation, stable operation, etc. compared with the beam pumping unit with the same rated load, it needs a smaller reduction box torque, a smaller motor power, and an obvious energy saving effect.

It is especially suitable for the exploitation of deep well, ultra deep well and heavy oil reservoir. During the workover, large hoisting equipment is not needed, and personnel can complete the work without climbing, which makes the work safe, reliable and easy.

Main Advantages of belt pumping unit:

1. Slow, Long Strokes: Long stroke make high coefficient of fullness, less fluid pounding;Slow period means less wear on downhole equipments and little cost.

2. Belt Transmission: A long life heavy duty belt transmission can absorb the shock during stroke reverse, thus effectively reduce the stress on downhole components to make rod strings run smoothly.

3. Low Torque Demand: The torque demand is greatly reduced due to the short torque arm which is only 0.46m.

4. Optimum Structure Design, Safety and Convenience: Two sets of brake systems with the automatic braking device ensure the units safety absolutely

5. High Reliability and Low Maintenance: perfect rigidity through optimum design.

6. Auxiliary system is fairly complete, not only for high volume production, but also for deep wells low volume production.

The belt pumping units is the patented product . It has mixed together major features and advantages of all kind of pumping units through years of research and development. As a unique engineering breakthrough, the 100% mechanical is especially suitable for producing high volume fluid in deep wells with rod pump and heavy oil recovery.

We had developed up to seven types. Lots of products had been exported to America, Canada, Cuba, Argentina, Kazakhstan, Uzbekistan, Middle East and other countries in addition to be using in Shengli, Dagang, Liaohe oilfield and almost every big oilfield in China.

It has proved that the pump unit with the international advanced level combines the advantages of high efficiency, reliability and energy saving.
