    摘要: The invention relates to a method for stopping a submersible pump when the pump is snoring, wherein the pump is operatively connected to a control unit. The method is characterized by the steps of regulating, by means of the control unit, the operational speed of the pump in order to direct an average power of the pump towards a predetermined set level, determining whether the instantaneous power of the pump is outside a predetermined range, by monitoring at least one of the parameters: power [P], current [I] and power factor [cosφ], determining whether the operational speed of the pump is increasing, and stopping the pump due to snoring, by means of the control unit, when the instantaneous power of the pump is determined as being outside the predetermined range at the same time the operational speed of the pump is determined as increasing.

    摘要: A hydraulic oil well pumping system is provided. The system uses a pump to exert hydraulic pressure against a reciprocating piston over a wellbore. The piston is connected to a rod string and downhole pump for pumping oil from a wellbore. The system includes an electronic control system that controls movement of the piston as it moves between the upper and lower rod positions by cycling the hydraulic system between (i) an “upstroke” condition wherein the pump is pumping oil through the oil line into the hydraulic cylinder to move the piston to its upper rod position, and (ii) a “neutral” condition wherein the pump is no longer pumping oil into the hydraulic cylinder, but is allowing oil to flow back through the oil line in response to gravitational fall of the piston. The control system is programmed to cycle based upon a volumetric calculation of hydraulic oil in the cylinder without reference to position sensors along the wellhead. Wellhead conditions or placement of the hydraulic cylinder inside the wellbore may prohibit attaching physical sensors at the wellhead. A method for pumping oil from a wellbore using such a system is also provided herein.

    摘要: The present invention describes a pumping device (1) for pumping fluids. The pumping device (1) comprises a force transmitting element (2), a tension unit (3) coupled to the force transmitting element (2) and a seal element (10). The force transmitting element (2) is adapted for transferring an upstroke and a downstroke to a pump plunger (5) for pumping fluid (12). The tension unit (3) is adapted for applying a tension force (F) to the force transmitting element (2) for keeping the force transmitting element (2) under tension during the upstroke and the downstroke. The seal element (10) is adapted for sealingly preventing pumping fluids (12) during the downstroke and for enabling pumping fluid (12) during the upstroke. A part (16) of the seal element (10) is rigidly coupled with the force transmitting element (2).

    摘要: The invention relates to a drive head, comprising a housing (12) with passages (24, 26) for the rod assembly (10) and a rotary-driven sleeve (30) which is arranged in said housing. Said sleeve (30) surrounds a section of the rod assembly (10) and is connected thereto by a coupling (40). A recoil brake (70) is provided for the controlled reduction of the torsion energy accumulated in the rod assembly. Said recoil brake (70) has a rotor (74) which is driven by means of the sleeve (30) and a stator (76) which is supported on the housing (12). The stator (76) is prevented from turning in relation to the housing (12) by a lock (82) which can only be released when the assembly (10) is essentially free of torsion energy. This ensures that it is safe to check whether the torsion energy has been essentially reduced.
