Definitions

• This invention relates to a method for setting up, controlling and operation of a waterworks, by use of a parameter representation of the waterworks, said waterworks is connected to a plurality of groundwater borings.
• the physical units consist of pumps, valves, flow gauges, level gauges, filters and other physical units connected to the waterworks.
• the operation conditions comprises determination of the levels in a clean water reservoir and in dependence thereof it is determined, when a given pump shall be stated or set stand by. It is also advantageous as stated in claim 7, that the filters in the waterworks are cleaned in dependency of its operation time and/or the amount of water flowing through the filters.
• Fig. 1 shows a principal construction of a waterworks
• Fig. 2 shows set up menu for controlling a waterworks
• Fig. 3A - 3D shows different process steps in the method according to the invention.
• Fig. 1 shows the principal construction of a waterworks, in which la a , lb, lc symbolic denotes groundwater borings comprising recovering pumps.
• the number of pump can vary, and some of them can be placed in the waterworks or in a distance therefrom.
• Water is pumped from the ground water borings la a , lb, lc through a flow gauge 2 and valves 4, 5, here shown parallel coupled filters 10, 11 having outlets 27, 28 and from the outlets 27, 28 through non shown filter material to a water reservoir 12 via valves 8, 9.
• the filter material can, depending on the water type, be a course filter or a fine filter. These filters is also called a for filter or a back filter. In the water borings actual water level is measured by use of level gauges
• a pump 16 pumps water from the water reservoir 12, via valves 6, 7 into the filters 10, 11 for cleaning those when it is necessary.
• water is pumped by pumps 17, 17 a , 17b, 17 c via flow gauges to the consumers.
• the pumps are connected to frequency converters 29, 29 a , 29b, 29 c that regulates the velocity of the pumps.
• a cleaning rinsing pump is provided, that is adapted to pump water into the filters 10, 11 for cleaning of those.
• a level gauge 14 a for measuring the actual level in a clean water reservoir 12 is connected to a junction box 15 that is connected to a control unit 20.
• This level gauge can be formed as a pressure transducer, where the measured water pressure corresponds to the level in the water reservoir 12.
• junction box To the junction box is further coupled an overflow detector 13 and a detector for registration of the minimal level in the clean water reservoir 12. These detectors are used for controlling the recovering pumps.
• 30a 30b denotes closing contacts for covers on the water borings, that in case that they are opened, shuts the pumps.
• control unit can have a communication link to other units, as shown at 21, that can be a telephone line.
• an efficiency gauge 23 is connected to a control unit 20, an extern stop contact 24, and a survive device 25 for surveying of the physical units.
• control unit 20 having a display 22, that comprises a calculation unit, such as a PLC unit, in which the calculation unit has a number of storage cells for connecting the physical units electrical outlets.
• calculation unit such as a PLC unit
• the storage cells are divided in groups each group representing a physical units electrical characteristic.
• fig. 2 the display 22 is seen, here shown a set up menu for activating icons for setting up and controlling a waterworks.
• activating icons namely one for basic information, one for borings one for filters and one for outlet pumping.
• activating icons such as a data icon can be added, depending of what kind of a waterworks is to be controlled.
• fig. 3A an illustration of the basic information from fig 2, when the basic information are activated by a pressure on the arrow.
• Fig. 3B shows a picture in which the activating icon for boring is activated. On the shown picture three borings are illustrated, where for the boring 1 is shown a quote (high-level curve) on 55,5 m, a distance on 25,5 m and level conditions for the boring expressed as an electrical value in the interval 4mA to 20 mA.
• the pumps are controlled as a start/stop function on basis of the preadjusted levels in the clean water reservoirs 12, such as, when the level for start (low level) is reached, a pump is started, that continues to pump until the stop level in the clean water reservoir 12 is reached. These levels are provided by the level detector 14 a .
• Pumps can be coupled in or out depending how much is pump from the clean water reservoir 12.
• the pumps can be controlled manually or automatically. Moreover, it is possible to show the current status of the pumps, being the number of stars for a pump, the number of running hours for a pump etc.
• the cleaning of the for filters is determined on basis of the out pumped water amount expressed in m 3 . That amount of water determine a clean can be decided by a user, having in mind that a boundary of a maximum of number of days that must be between cleaning must be met.
• the cleaning itself can be done by units Ml, M2 as a sequence consisting of cleaning with air, cleaning with air and ware and cleaning with water, and having a stop between the cleaning activities.
• M3 s denotes a unit, that provides air to the filters under operation.
• Fig. 3D shows a picture of the activating icon out pumping and the conditions bound to them.
• These pumps can be controlled such, that a wanted pressure and flow are provided.
• the pump is controlled after requirement, and data such as the number of operation hours are surveyed.
• data such as the number of operation hours are surveyed.
• the outline for pumping as an example is shown as 38 Hz and 46 Hz. These values is chosen for instance for meeting a max value of the efficiency of pumps is met.
