Definitions

  • the invention relates to a sewage lifting plant, comprising a feed pump, in particular a centrifugal pump, with a suction opening and Pressure opening, the pump being held in this way by a holding device, that the suction opening is at a distance above the bottom of a waste water container the wastewater lifting station, and the pump is replaced by a Level control device can be controlled in such a way that when a first level is reached predeterminable or adjustable level of the waste water switches on and either when a second predefinable or adjustable level is reached the wastewater or after a predetermined time.
  • Such wastewater lifting plants are generally known. You will be through different level control systems controlled by the feed pump is switched on or off when certain water levels are reached.
  • the largest possible Switching volume aimed for which is generally as large as possible Base area of the waste water tank and / or by the highest possible Switched on level and / or the lowest possible switch-off level reached can be.
  • the level of the switch-off level can only be reduced to the extent that a certain safety distance to the suction opening of the feed pump is guaranteed, otherwise there is a risk of air being sucked in could.
  • the switch-off level of the Level control can no longer be achieved, so that the pump no longer is turned off.
  • the lowering of the switch-off level is limited by the fact that between the bottom of the waste water tank and the suction opening of the Feed pump must have a certain minimum distance to the free passage of any wastewater present To ensure solids.
  • the object of the present invention is therefore to provide a structurally simple, inexpensive to manufacture and easy to handle sewage lifting plant to create the type mentioned at the very low Switch-off level enables the largest possible switching volume without the restrict the free passage of solids and without the safe Risk of reaching the switch-off level.
  • the main advantage is that a very low switch-off level is achieved without the risk that the shutdown level due to the suction of air is not achieved and without the free passage is restricted by solids. This can help ensure optimal Operating mode of the wastewater lifting plant desired large switching volume can be achieved without the footprint of the waste water tank or the height to increase the switch-on level. On the other hand, one can predetermined switching volume even with a relatively small footprint of the Wastewater tank and reached without the risk of air intake become.
  • the pipe section can optionally in Waste water flowing solid parts on the wall of the pipe section Push the contact point away so that the required passage is released. after passing the solid part, the pipe section springs into its Initial form back.
  • the pipe section is made of an elastomer material consists. It can preferably also be formed by a piece of hose his.
  • the system according to the invention is inexpensive with a simple construction to manufacture and easy to assemble and handle.
  • a particularly simple construction and assembly can thereby achieved that the pipe section in a form-fitting and / or non-positive the suction opening of the pump is inserted.
  • the pipe section can also be cohesively attached to the edge areas of the pump surrounding the suction opening be, which is a particularly safe and tight arrangement of the Pipe piece results.
  • the pipe section is different from the Suction opening of the pump extends vertically downwards. In this way can be a particularly simple lowering of the Switch-off levels can be reached.
  • a particularly simple, compact and inexpensive construction can be achieved in that the holding device is integral with the Pump housing is formed.
  • the drawing shows a pump 1 of a sewage lifting system according to the invention 2, the bottom of a not shown Waste water container 3 is used.
  • Pump 1 is a centrifugal pump an impeller 4 formed around the vertically arranged impeller axis 5 rotates.
  • the pump 1 is arranged such that the suction opening 7 of the pump housing 8 coaxial to the impeller axis 5 is located above the bottom 9 of the waste water container 3.
  • the pressure port 10 the pump 1 is at the upper end of an upward bent Pressure port 11.
  • a short blank 12 from a is in the suction opening 7 flexible elastomer material is used, which extends coaxially vertically downwards extends in the direction of the bottom 9.
  • the pipe section 12 has at its upper first end 13 has a collar 14 with an annular groove open to the outside, in which lie in the edge areas of the suction opening 7 of the pump housing 8. In this way, the pipe section 12 is positive and non-positive on the Pump housing 8 attached.
  • the waste water is in this way through the lower free end 15 of the Pipe piece 12 sucked through, the pipe opening at the bottom free End 15 of the pipe section 12 by the amount ⁇ H with respect to the suction opening 7 of the pump housing 8 is shifted downwards.
  • the respective safety distances S also result in the amount ⁇ H, um the achievable new switch-off level A below that previously the lowest possible switch-off level B.
