Definitions

  • the invention relates to a pumping station, comprising a building, which has at least one inlet space and at least one arranged at a different level drainage space between these at least two rooms a partition wall is disposed within the building, at least one pump fluid through such a partition in a Spout space of the building promotes the discharge space has an angle to an outlet opening arranged discharge opening, wherein the upper edge is located below a liquid level, which prevails in a downstream of the building drain.
  • Pumping stations also known as scooping, dike or relief scooping, Wasserhebewerke, irrigation pumping stations or under similar terms, must promote large volumes of water at low heights.
  • a general overview of such installations is given in the article '' Design of Schöpftechnike ", by Helmut Gschreibke and Paul Winkelmann, published in KSB Technical Reports No. 11, August 1966, pages 28-36 , known.
  • Pumping stations have to cope with different delivery heights with changing inlet-side levels and with fluctuations in the outdoor water levels downstream of the pumping station. Since the use of pumps, essentially of axial or semi-axial design, provide only relatively small delivery heights, the required for an efficient operation of the plant small variations in the delivery height for the design of such pumping stations is a problem.
  • the pump drive is provided with an angle drive and an integrated planetary gear. This serves to reduce the height in the building of the pumping station, since the drive motor can be installed horizontally. And with the planetary gearbox. In addition, a speed adjustment of the pump.
  • GB 2 027 470 A is a backflow preventer of a domestic sewage plant known, which can be regarded as a kind of precursor of today's sewage lifting equipment.
  • a pump is additionally arranged to allow for a backflow Abpoundau a temporary pumping.
  • the design of the non-return valve is backpressure-proof, as an internal partition with integrated non-return valve can be overflowed.
  • the GB-A-1 070 259 discloses for a manually operable toilet flush a system separator, with the help of a backflow of contaminated liquid is prevented in a drinking water system.
  • the invention is based on the problem to develop a pumping station, which ensures a safe and energetically favorable operation with low technical equipment and construction effort.
  • An embodiment of the invention provides that the upper edge of the drain opening is part of an adjustable opening.
  • the upper edge of the drain opening is part of an adjustable opening.
  • Another embodiment of the invention provides that in the liquid-conducting device and / or in the region of the discharge opening a flow rate measuring device is arranged.
  • the outflow opening can be arranged downstream of a predominantly horizontally extending discharge channel, a line or the like with a delivery-flow measuring device arranged therein.
  • a conveyor flow measuring device makes it possible in the simplest way to monitor up to remote diagnosis or remote maintenance of a pumping station. With the aid of a conveying current signal that can be transmitted in a different and known manner, it can be determined whether the pumping station is operating as intended.

  • a pump is equipped with fixed and / or adjustable running and / or guide devices.
  • the use of such adjustment depends on the operating conditions that are used for the pumping station.
  • the use of such pump types in a pumping station increases the investment costs, but they cause compared to so-called rigid, that is not controllable pumps, an improvement in efficiency. And this causes a significant reduction in electricity costs, which seen over a longer period of operation, such a system is cheaper to operate. Saving on energy costs reduces the lifecycle costs of the system for the operator.
  • the liquid in the ascending direction leading device is perpendicular or inclined, wherein the outlet opening is arranged parallel or inclined to the liquid level.
  • the surface of the outlet opening can also be inclined at an angle and / or relative to the horizontal. It must, just as with a horizontally extending outlet, only be ensured that a lowermost edge of the outlet opening is always located above the highest liquid level, which has been used in the planning of the pumping station on the outflow side. With this measure, it is prevented when switching off a pump that an already funded fluid flows through the outlet opening and through the pump back into the inlet chamber.
  • the outlet or its lowest edge is, albeit only slightly, always above the maximum occurring liquid level.
  • the construction-side training of the pumping station can thus be designed directly as a lifter, without having to install the previously known special lifter pipes additionally.
  • the lower Heberscheitel forms in this case the outlet opening of a pump downstream liquid leading means.
  • the design of the outlet space as a lifter is directly related to the energy savings potential of the pumping station by recovering the geodetic height difference between the bottom elevation of the heel and the level on the discharge side. This is ensured by the position of the upper edge of the discharge opening at the level of the lowest water level on the discharge side.
  • the discharge space of the pumping station When switching off the pump, the discharge space of the pumping station is ventilated by means of a fitting, whereby the lifting effect is canceled.

  • Such a design of the pumping station makes it possible to dispense with the long lifting pipes previously used. Due to the low in this solution return quantities of the pump-side backup effort against backflow can be completely eliminated or under certain circumstances only be kept low.
  • a vacuum system for venting the discharge space can be additionally provided. This would then only during the startup of the pump in operation. Depending on the design of the pumping station and its operating conditions would be to decide whether, for example, a stronger pump drive motor or a vacuum system is given preference.

  • the drainage room would be connected to the environment.
  • the existing in the fluid device, generated by the pump dynamic pressure components of the flow are not sufficient to bridge the height level to the drive unit.
  • a shaft seal can be saved for the pump shaft, as set in the wave protection tube, a fluid level, due to which no air could enter from outside into the discharge space and affect the lifting effect.
  • the shaft protection tube can also be used to suspend the hydraulic unit from the pump in cases where a drawable hydraulic system is used.
