Definitions

  • the invention relates to a hydraulically driven diaphragm pump the preamble of claim 1.
  • the invention has for its object a hydraulically driven diaphragm pump of the type mentioned above to improve that with simple mechanical means maintain a fluid balance in the hydraulic room becomes.
  • the rod-like slide is guided in a guide bore, which is in the hydraulic room.
  • the slide ensures in the suction stroke limit position making a first hole with the suction valve, which is preferably in the reservoir is arranged, is connected to possibly hydraulic fluid from the reservoir suck up.
  • a second hole is made with the guide hole connected. The second hole is also connected to the reservoir, so that in the position described hydraulic fluid in the reservoir can flow if there is a corresponding displacement by the hydraulic piston takes place.
  • a part facing the membrane has of the rod-like slide on a smaller diameter section, the one second bore leading to the slide valve covers when the membrane is in the suction stroke limit position is for the purpose of connecting the suction valve to the guide bore and thus with the hydraulic room.
  • the slide forms also a second valve that keeps the diaphragm flowing during the suction stroke prevented from hydraulic fluid from the reservoir into the hydraulic space.
  • the first and second are Bore formed in a component that also has the guide hole and that on the side of the reservoir inside the hydraulic room, preferably on the Wall that separates the hydraulic room from the reservoir (water tank).
  • the component may have a flange that is against the reservoir-side wall of the pump body is brought to the system when the component through an opening in the Wall is led into the hydraulic room.
  • the suction valve can on the flange be attached.
  • the unit consisting of component and suction valve can be manufactured separately and then simply screwed onto the pump body be attached.
  • the rod-like slide is according to another embodiment of the invention with a Plate connected, for example via a screw connection, which is preferably in the preformed membrane is vulcanized.
  • the pump body points on the suction side preferably a straight conical surface to which the membrane is attached can put on when the membrane reaches or exceeds its suction stroke limit position. Damage to the membrane can thereby be avoided.
  • the Channel between the suction displacement and the hydraulic space is preferably over made a large diameter bore, which the rod-like slide surrounds.
  • a pump body 10 and a pump cover 12 or 14 is one preformed membrane 16 or 18 clamped.
  • the preform is on the membrane 16 to recognize, which forms a circumferential bead 20 in the pressure stroke limit position.
  • a pump chamber 22 and 24 respectively via a ball valve 26 or 28, 30 or 32 with the suction and pressure side of the Pump is connected.
  • the structure is conventional and should therefore not continue to be discribed.
  • a cylinder 34 is arranged in the pump body 10 and is connected at one end to a Hydraulic space 36 and at the other end with a hydraulic space 38 in connection stands.
  • a piston 40 which is not one Drive shown oscillating is driven to the hydraulic spaces 36, 38th optionally under pressure or vacuum. This will make the membranes 16, 18 moved in a known manner oscillating between the limit positions, such as this is also generally known.
  • hydraulic fluid 44 e.g. B. water
  • the hydraulic rooms 36, 38 are also in operation completely filled with hydraulic fluid.
  • a metal plate 46 is vulcanized into the membrane 16.
  • a rod-like slider 48 is connected to the plate 46 via a screw connection 50.
  • the slider 48 has a first section 52 and a second section 54.
  • the second section is guided in a guide bore 56 of a component 58.
  • the Section 52 has a smaller diameter than section 54.
  • In the guide bore 56 open two holes 60, 61.
  • the component 58 is passed through an opening in a wall 62 which the Water box 42 separates from the hydraulic space 36.
  • the component 58 has a flange 64 on, which comes to rest on the water box side against the wall 62 and there is attached by means of screws.
  • a valve 66 is also connected to the flange, which has a kickback function, its ball usually using Spring pressure is at an upper sealing seat. Thus the valve prevents hydraulic fluid flows from the hydraulic chamber 36 to the water tank 42 when a corresponding pressure is built up in the hydraulic chamber 36.
  • a safety device can also be provided in the event of a diaphragm rupture, which indicates this in good time and if necessary prevents hydraulic fluid from flowing into the pump chamber 22 or 24.
