Definitions

  • a pump station generally consists of an upper part and a lower part.
  • the upper part functions as control room and the lower part as collecting room for waste water.
  • One or more pumps are provided in the lower part, to pump the waste water to a discharge pipe.
  • Both non-return valves and stop valves are arranged between the pumps and the discharge pipe and these valves are normally arranged in the control room itself.
  • the non-return valves have a tendency to clog and require a certain amount of service.
  • the pumps too require a certain amount of service.
  • the stop valves require substantially no service.
  • the object of the present invention is to eliminate the abovementioned drawbacks and this is achieved by constructing the pump and its non-return valve as a single unit which can easily be lifted from its operating site for inspection in a different place.
  • Said unit can be considered as a "plug-in unit" in that one unit in a pump station can be replaced by a similar unit.
  • control means are required to remove the unit consisting of pump and non-return valve.
  • Said control means are also required to place said unit in its work place.
  • the unit consisting of pump and non-return valve has an outlet opening with a flat end surface for cooperation with an inlet opening with a flat end surface pertaining to a connection arranged in the lower part of the pump house and in communication with the waste-water pipe or discharge pipe of the pump house.
  • connection according to the present invention is arranged with a number of inlet openings corresponding to the number of units comprising pump and non-return valve.
  • Suitable operating means may be an extended shaft with wheel.
  • connection has only one valve which can produce a connection between the waste-water pipe and one or more of the pumps.
  • control means comprise one guide for each "plug-in unit", said guides cooperating with individual stop valves either by beinjg pivotable about their longitudinal axis, in which case the pivoting movement is utilized to open or close the cooperating stop valve, or by being hollow, in which case a rod is arranged through each hollow guide to open and close the cooperating stop valve.
  • a second essential feature according to the present invention is that the closing movement of each non-return valve occurs against a counteractive force in order to prevent sudden impact upon closing.
  • Said counteractive force may consist of a spring force or it may be maintained hydraulically.
  • Another possibility is to use a means acting in the same manner as the bumper on a car.
  • Fig.1 shows a pump station including units comprising pump and nonreturn valve, said units being in their operative position,
  • Fig.2 shows the same pump station as Fig.1, but with one unit comprising pump and non-return valve is being removed from its operating position, and
  • Fig.3 shows a pump station with pump and non-return valve as a unit located outside the pump station.
  • FIG. 1 is the lower part of a pump station consisting of two parts located one on top of the other.
  • the lower part 1 is provided at the top with a peripheral flange 2 and supports 3 for said peripheral flange.
  • a floor M is located on the peripheral flange, and above the floor an upper part 5 having a door 6, a skylight 7 and a ventilation pipe 8.
  • the lower part 1 is provided with a pipe socket 9 for con- nection of a pipe supplying the lower part 1 with waste water.
  • the lower part is connected to a discharge pipe 10.
  • Two units 11 and 12 are arranged in the bottom of the lower part, each consisting of a pump and a non-return valve. In the unit 11 the pump is designated 13 and the non-return valve 14.
  • the pump is designated 15 and the non-return valve 16.
  • Non-return valves 14 and 16 may be KG nonreturn valves PN 10, marketed by Ahlsell & Agren and described in their prospectus sheet for September, 1976.
  • the orifice of connection 19 outside the lower part 1 is in a pipe socket 9 for connection to the discharge pipe 10.
  • the connection 19 is provided with a foot 30 for application on the bottom of the lower part 1.
  • each non-return valve is provided with a flap 38 which blocks the flow in opposite direction.
  • the unit comprising pump and nonreturn valve will be termed "pump unit" in the following.
  • the pump unit 11 is provided with an outlet opening surrounded by a flange 17.
  • the flange 17 and edge of the outlet opening together form a flat contact surface abutting and cooperating with the branch pipe 18 of a connection 19.
  • the branch pipe 18 forms an inlet opening to the connection 19 and has a flat end surface cooperating with the flat surface of the pump unit at its outlet opening.
  • the branch pipe 18 is also provided with a flange 20 like the outlet opening to the pump unit 11.
  • the pump unit 12 is connected to a branch pipe 21 also having a contact flange 22 and the pump unit 12 having a contact flange 23.
  • Each branch pipe 18 and 21 has a stop valve 2-4 and 25, respectively.
  • the stop valve may be a Beta sluice valve NT 4 of make Ahlsell 4 Agren.
  • Such a sluice valve is described in prospectus A ⁇ -no.580008.
  • An operating shaft 26 is attached to the stop valve 24 and extends to the upper part 5, and is provided at the top end with a control wheel 27.
  • the stop valve 25 is similarly provided with control shaft 28 with wheel 29.
  • Guides 32 and 33 are provided for the pump units.
  • the guide 32 and lever 34 control the horizontal position of the pump unit 11.
  • the latter unit is also provided with guide fingers 36 to control the pump unit 11 laterally.
  • the pump unit 12 is also provided with similar guide fingers 37.
  • Each pump unit 11 and 12 is provided with a hoisting wire 38 and 39., respectively. It is no doubt evident that the guides may be of a different length provided the function described below is fulfilled. Their upper ends might terminate at the lower side of the floor 4.
  • the means described functions in the following manner. It is assumed that the two pump units 11 and 12 are in the positions shown in Fig.1. If one pump unit, 12, is to be inspected it need only be lifted straight up by means of the hoisting wire 39. During the first stage of lifting the lateral movement of the pump unit is controlled by the flat contact surfaces between the outlet opening of the unit 12 and the inlet opening of the branch pipe 21. The pump unit can then be moved sideways and vertical movement is controlled by the guide 33. When the pump unit 12 has reached the control room it is transported to workshop premises for service and is replaced by an identical unit fitted to the guide 33 and lowered to the lower part 1.
  • the control fingers 37 When the pump unit approaches the branch pipe 21 the control fingers 37 will come into operation to bring the flat end surface of the unit's output opening parallel to the end surface of the inlet end of the branch pipe 21. Contact between the two flat surfaces provides adequate sealing between the branch pipe 21 and the outlet opening of the pump unit.
  • the two branch pipes can be opened and closed by the valves 2-4 and 25 via operating shaft 26 with its wheel 27 and via operating shaft 28 with its wheel 29. Lateral control of the pump unit when moving up and down can also be achieved by other control means, such as by arranging grooves in the guides and by inwardly directed pins or ridges arranged on the support arms of the pump units and cooperating with said grooves.
  • outlet pipe socket is also a great advantage for the outlet pipe socket to be arranged at the bottom of the pump station as this greatly facilitates cooperating with the discharge pipe.
  • the present invention offers a pump unit which can easily be removed for inspection and replaced by a spare pump unit. All inspection of such a pump unit can therefore be carried out in premises specially for the purpose. This avoids the pump station being used for servicing purposes for which it is unsuitable. It should be evident that the upper part 5 and floor 4 can be replaced by a lid, in which case the components arranged in the control room according to Fig.1 must of course be limited in axial extension.
  • the two guides 32 and 33 may be pivotable about their longitudinal axes. Due to their pivoting ability they might replace the operating shafts 26 and 28, the guides then being connected to the stop valves 24 and 25. There are then only two rodlike units in the lower part 1.
  • the guides 32 and 33 are used to open and close the stop valves 24 and 25. Another possibility is for the guides to be hollow and the operating shafts 26 and 28 for opening and closing stop valves 24 and 25 to be located inside the guides.
  • a force is arranged to counteract a closing movement, thus closing the non-return valve gently.
  • the force may be provided by a spring, a hydraulic means or a member acting in the same way as the bumper on a car.
