RM (ReverseMark) Pumping Unit

Date:2024-05-06 Popularity:880

RockySea Petro RM Pumping Unit

  • Using AutoCAD, Solid Works computer software to design drawings, using virtual prototype technology to simulate and verify strength.
  • RockySea Petro adopt the principle of combining International Standard, National Standard and User’s view to design.
  • RockySea Petro has passed ISO9001, SO14001 and OHSAS18001 certificate.

RM pumping unit is designed on the basis of conventional beam pumping unit, which can change the time of up and down stroke of the pumping unit and is suitable for heavy oil recovery.

Description 

RM (Reverse Mark) pumping unit is based on the conventional beam pumping unit, which optimizes the four-rod structure and designs the out-of-phase angles on the crank. The operation of conventional beam pumping unit is limited by its own structure, which has low stability, low efficiency and high energy consumption. RM pumping units with crank out-of-phase angles take different time to run up and down strokes. The longer upstroke time and the lower average speed of the horsehead can increase the downpump’s filling coefficient and extract more oil for the same unit of energy consumption. It’s more efficient and uses less energy.

reverse mark pumping unit structure diagram

The RM pumping unit has changed the connection mode between the beam and the beam, and the tail of the beam is at an Angle of 20°. According to calculation, this structure can make the four-bar mechanism of the pumping unit operate more stably, reduce the impact force of load on the connecting bolts, and ensure the service life under the maximum impact load.
