Definitions

  • the invention relates to a rinsing liquid pump system, with a pump unit and with a rotary drive device for driving the pump unit.
  • flushing liquid pump system refers to a pump system which conveys flushing liquid which flushes through the borehole during the advance or drilling of boreholes.
  • flushing fluid is supplied to the borehole during the drilling process.
  • the flushing liquid is used on the one hand to lubricate the drilling tools working on the working face or on the bottom of the borehole and to support the working face or the borehole wall.
  • loosened drill cuttings can also be brought out of the borehole, for example by supplying fresh rinsing liquid centrally through a hollow drill string in the area of the bottom of the borehole or the working face, thus generating a rinsing liquid flow that entrains loosened drill cuttings and out of the drilling out.
  • the pumping capacity of such pump systems is regularly in the range of a maximum of 3000 l/min and a maximum pressure of 500 bar.
  • the state of the art includes pump systems which are distinguished by a particularly compact design, since the rotary drive device of the pump system which drives the pump assembly is arranged above the pump assembly and is flanged to the upper side of the housing.
  • the rotary drive devices regularly have outputs of up to 1,700 kW.
  • the GB-A-1034058 concerns improvements to a sun and planetary gear. Although this document discloses using these improvements, which comprise a rotary drive device and a gear train comprising a drive wheel and a driven wheel, in connection with a pump arrangement, this is intended for use in the confectionery industry. This document therefore does not contain any indications as to how to design a rinsing liquid pump system in the manner according to the invention.
  • the U.S. 2004/0060717 A1 relates to a drilling device with a compact compressor-pump arrangement.
  • the pumps are hydraulic pumps which are used to provide the pressure required to actuate the drilling device, for example rotating and positioning the mast, by means of hydraulic cylinders or hydraulic motors.
  • the compressor is used to produce compressed air, which is used to extract drill cuttings from the well.
  • the compressor and pumps are flanged together into one unit and connected via gears to a drive axle driven by a rotary motor. Again, the subject of this document is not an irrigation fluid pump.
  • the U.S. 2004/0028540 A1 refers to a manually driven pump or compressor assembly. Although in the embodiment shown in FIG. 3 an operative connection is established between the manual drive and the pump or compressor device by means of meshing gear wheels, this document has no connection with a rinsing liquid pump system.
  • the U.S. 2004/0219040 A1 shows a device with a summation gear, which is used to bundle the power of several motors. This document does not contain suggestions for a rinsing liquid pump system with precisely one rotary drive device.
  • the US2004/0219042 shows a pump arrangement with a motor.
  • the CN 2 385 075 Y discloses a mud pump assembly. It comprises a pump housing in which a drive shaft is mounted, which has a first gear wheel which is in mesh with a second gear wheel of a crankshaft which is also mounted in the housing.
  • the drive shaft carries a belt pulley, via which the scavenging pump unit is coupled to an external rotary drive device that is not described in detail.
  • the U.S. 2,883,874 discloses a scavenging pump with a pump unit, which includes a crankshaft provided in a crankcase.
  • the crankshaft is connected to a worm gear provided in a gear case.
  • the transmission housing is arranged laterally next to the crankcase and projects beyond the crankcase in the vertical direction, also downwards.
  • a worm shaft protrudes from the gearbox housing to connect a drive motor.
  • the U.S. 4,435,990 discloses a portable transmission unit for interposing between a driving source and a driven source, in particular for connecting an industrial engine to a scavenging pump.
  • the drive motor, gear unit and scavenging pump are arranged side by side.
  • the invention is therefore based on the object of creating a pump system which does not have the aforementioned disadvantages.
  • the rotary drive device is operatively connected to the pump unit via a gear train comprising a drive wheel and a driven wheel, the noise development inherent in a chain drive is avoided. Furthermore, it has surprisingly been found that, in order to transmit the power and torque required to operate the pump unit, it is sufficient to provide a gear train on only one side of the pump system.
  • a pump system in which the rotary drive device has only a single shaft end with which the drive wheel can be connected in rotation via a coupling.
  • the noise level caused by the gear train can be further reduced if--as is particularly preferred--the gear wheels of the gear train are helically toothed.
  • the pump system 100 includes a pump assembly 1 of conventional design.
  • This pump assembly 1 includes a housing 2, from the side facing the viewer one end of a pump drive shaft 3 protrudes. With this shaft end, the output gear 4 of a gear train 5 is rotatably connected.
  • the toothed wheel gear 5 is used to produce the operative connection of the pump unit with a rotary drive device 6, which comprises a rotary motor R, which is only indicated in the drawing and is driven, for example, hydraulically or electrically.
  • the rotary drive device 6 includes a housing 7 which is flanged to the housing 2 of the pump unit 1 .
  • a shaft end of a driven shaft 8 protrudes from the housing 7 of the rotary drive device 6 . It is connected to a drive wheel 9 via a clutch 12, which selectively connects or releases the drive wheel 9 in a rotationally fixed manner to the end of the shaft.
  • the drive wheel 9 is coupled to the driven wheel 4 via an intermediate wheel 10 which is rotatably mounted in a housing 11 of the gear train.
  • an elastic, non-shiftable clutch can also be provided, which permanently connects the shaft end to the drive wheel.
  • the toothing of the intermediate wheel 10 is in mesh with the toothing of the drive wheel 9 and the driven wheel 4.
  • the wheels of the gear train are helically toothed to reduce noise.
