Definitions

  • the invention relates to a transmission for one in one Conveyor pump set up in a deep borehole with the characteristics of The preamble of claim 1.
  • Rotating deep well pumps, especially for production of petroleum are placed at the foot of a borehole. you will be over a rotating rod that protrudes beyond the borehole, driven by an electric motor via a gearbox.
  • the Actuator rod has only one in relation to its length small diameter. When introducing a torque to The drive of the deep borehole pump twists the drive rod in the elastic range and thus acts as a torsion spring can store a lot of energy according to its length. At the Switching off the electric motor or even in the event of a power failure stored energy released and over the Transmission output shaft in the transmission and the electric motor initiated.
  • WO 88/07126 describes a generic transmission for an in a deep well installed feed pump known with a centrifugal brake to break down the in the drive train Feed pump stored energy is provided.
  • the Centrifugal brake engages the input shaft of the gearbox and slows them down from excessive speeds tolerable speeds.
  • Such mechanical Friction brakes have the disadvantage that these brakes do them are difficult to dose, subject to high wear and that the pump shaft remains under tension (Danger of accident).
  • WO 97/10437 describes a drive for a deep borehole pump known in which a liquid pump for controlled degradation the stored energy from the transmission output shaft is used.
  • the liquid pump is over one Overrunning clutch connected to a shaft of the transmission. at normal operation, i.e. with the direction of rotation of the Downhole pump will not rotate from the freewheel transfer. In the opposite direction of rotation the Rotational movement initiated in the liquid pump. This sucks the liquid pump from a reservoir a viscous Liquid on and promotes this again via a throttle valve back.
  • the throttle valve is set or dimensioned so that that a gradual degradation of the stored energy takes place and the drive in the permissible speed range remains.
  • DE 534 429 embodies a gear pump Braking device for the driven shaft of differential gears described, the task of which is Rotational speed of this shaft in both directions regulate.
  • the pump housing with the two rotating ones inside Gears of this gear pump is on lines in which Control valves and check valves are arranged with a external oil tank connected.
  • This braking device is relatively expensive, since an external storage tank and external lines secured by valves for the Provision of the liquid are required.
  • the invention has for its object the generic To design gearboxes in such a way that the stored energy comes from the output shaft is broken down in a controlled manner in a simpler manner can be.
  • a gear pump is in the transmission integrated, which acts as a reverse brake.
  • the input shaft can necessarily vertically arranged output shaft horizontally become. This creates an overall compact gearbox Drive a deep well pump.
  • the invention is based on the idea that a Gear pump for conveying liquids is known to be the Delivery direction depends on the direction of rotation. In the Invention this is so by the arrangement of the gear pump exploited that in the operating direction of rotation of the gearbox air is sucked in on the inlet side and therefore none Liquid delivery takes place.
  • the opposite Direction of rotation that occurs when the gearbox through the stored energy from the output shaft of the transmission and the associated drive linkage of the deep well pump is driven, fluid is conveyed and pressure built up, since the inlet side is below the Liquid level. Oil becomes the liquid used, which also serves as a lubricating oil for lubricating the Gearbox serves.
  • the oil is pumped into a pressure chamber.
  • the pressure chamber is connected to the gearbox interior via a throttle connected.
  • the throttle causes an increase in pressure and thus a controlled breakdown of the stored energy. With increasing speed increases the torque of the gear pump, which is used for braking.
  • the gear is an angular gear and has a horizontal Input shaft 2 on one end in a gear housing 1 protrudes and at this end one with external teeth provided bevel pinion 3 carries.
  • a drive not shown, for. B. a Electric motor.
  • the input shaft 2 is in two bearings 4.1, 4.2 stored, which can be the same or different.
  • the bevel pinion 3 meshes with a corresponding one External toothing provided bevel gear 6, which is on a vertical arranged, hollow output shaft 5 is rotatably attached.
  • the Output shaft 5 is in two bearings 7, 8 and in a thrust bearing 9 stored in the gear housing 1.
  • the output shaft 5 is over a rod rod, not shown, with a likewise Feed pump, not shown, arranged in a deep borehole connected. This feed pump is used to extract petroleum.
  • the interior of the gear housing 1, in which the bevel pinion 3rd and revolve around the bevel gear 6 is partially up to one designed liquid level with lubricating oil filled.
  • the gear housing 1 is on one side through a cover 19 closed. On the opposite side are on the Gearbox housing 1 screwed two bearing flanges 12, 14 in which the bearings 4 supporting the input shaft 2 are provided. Out the input shaft 2 is sealed to the outer bearing flange led out.
  • a pump flange is located between the two bearing flanges 12, 14 13 clamped, which has an inner cavity. Within the cavity of the pump flange 13 is on the input shaft 2, a first gear 10 is attached in a rotationally fixed manner. The first gear 10 forms with a second one in the cavity of the pump flange 13 arranged gear 11 a gear pump.
  • the one pump chamber 15 of the gear pump stands with the Lube-filled interior of the gearbox 1 below of the liquid level in connection.
  • the other Pump chamber 16 is connected to a return flow channel 18, which in the interior of the gear housing 1 above the Liquid level empties.
  • a throttle 17 installed in the return flow channel 18 .
