Definitions

  • the present invention relates to a control device and a method for controlling a pump test run, in particular in a water extinguishing system.
  • Water extinguishing systems within the meaning of the invention are in particular sprinkler, spray water and foam extinguishing systems, whereby the invention is not limited to particular types of water extinguishing systems.
  • the present invention particularly relates to water extinguishing systems comprising a fluid supply for providing an extinguishing fluid, a pump configured to convey the extinguishing fluid from the fluid supply into a supply line of a pipe system of the water extinguishing system, and a sampling line branching off from the supply line of the pipe system and configured to direct the extinguishing fluid conveyed by the pump away from the pipe system.
  • the sampling line has an opening member configured to be movable between a blocking position, in which the opening member closes the sampling line, and an unlocking position, in which the opening member opens the sampling line.
  • the water extinguishing system further comprises a fluid diversion having a reduced cross-section compared to the sampling line, wherein the fluid diversion is configured to direct a predefined portion of the extinguishing fluid around the opening member away from the pipe system.
  • the fluid supply is understood to be a combination of one or more elements that serve to supply the water extinguishing system with extinguishing fluid.
  • the fluid supply may, in particular, comprise a drinking water supply from which drinking water can be supplied to the water extinguishing system as extinguishing fluid.
  • the fluid supply may comprise a storage tank in which the extinguishing fluid can be stored.
  • a test line is typically understood to be a water measuring device comprising a flow meter, settling sections, and regulating valves for testing the water flow.
  • the test line is preferably provided as a branch from the supply line to the pipe system of the water extinguishing system, in particular as a branch from the distribution pipe downstream of the pump, which serves to supply the pipe system.
  • a distribution pipe specifically describes a pipe that either directly feeds a branch pipe or a single sprinkler on a branch pipe that does not have a tailpipe and is over 300 mm long. The pipes that serve to supply the pipe system thus form the supply line to the pipe system.
  • the test line is used to carry out a so-called pump test run, in which the functionality of the pump of the water extinguishing system can be tested.
  • the test line comprises an opening element.
  • An opening element is understood in particular to be a sliding element within an opening unit, such as a valve, which can be operated manually according to the prior art. Opening is achieved by moving the sliding element from a blocked to an unlocked position.
  • the opening element in the test line is opened. This enables a volume flow through the test line, by means of which a pump test run can be carried out. Closing then occurs by moving the sliding element from the unlocked position to the blocked position. This interrupts the volume flow through the valve.
  • the test line is therefore the line that is used for the pump test run in the case of a manually carried out pump test run in order to form a test circuit.
  • the test line is opened for the duration of the pump test run, and on the other hand, the supply of extinguishing fluid to the pipe system is prevented. This ensures that the extinguishing fluid is guided within the test circuit created by the test line during the test run.
  • the extinguishing fluid is led away from the pump through the test line and then either into a corresponding The extinguishing fluid reservoir and/or a drain are then directed. This means that no extinguishing fluid is introduced into the pipe system. Only after the pump test run is the test line closed again and the fluid supply to the pipe system restored. After that, the extinguishing fluid can flow back into the pipe system.
  • a fluid bypass is understood to be an additional line provided in addition to the test line, which can also branch off either from the supply line to the pipe system or from the test line.
  • the fluid bypass is characterized in that it has a cross-section that is much smaller than that of the test line.
  • the cross-section of the fluid bypass corresponds, for example, to only 2 to 10% of the cross-section of the test line, and in other embodiments even less.
  • the cross-section of the fluid bypass is selected such that it conducts in particular 2% of the pump's flow rate.
  • the fluid bypass is also referred to as an emergency line.
  • the fluid bypass is designed such that it directs the extinguishing fluid pumped by the pump away from the pipe system even when the opening element in the test line is in the blocked position. The fluid bypass therefore serves to direct the extinguishing fluid away from the pipe system around the opening element.
  • extinguishing fluid therefore refers to a fluid used to extinguish and/or fight fires.
  • This extinguishing fluid can, in particular, be extinguishing water, provided with or without additives.
  • the extinguishing fluid can contain a foam, an antifreeze agent, or similar.
  • the additives should, if possible, be selected to be optimal for the specific application of the water extinguishing system.
  • the extinguishing fluid can also be pure extinguishing water. Other extinguishing fluids are also conceivable.
  • VdS 2212 Water extinguishing systems of the aforementioned type are subject, among other things, to the regulations described in VdS 2212.
  • paragraph 1.3.4 of VdS 2212 stipulates weekly inspections of the water extinguishing system by the system operator.
  • the weekly tests include a check of the pump start-up of the pump used to deliver the extinguishing fluid. This requires a so-called pump test run, which must last until the pump's normal operating parameters are reached.
  • test line is usually used in such water extinguishing systems, which enables a pump test and prevents the extinguishing fluid
  • the areas monitored by the water extinguishing system are flooded weekly.
  • This test line can be opened using the opening device for the purpose of the pump test run and closed again after the pump test run is completed. This makes it possible to provide a kind of "test circuit" for the duration of the pump test run, thus avoiding flooding of the monitored areas.
  • the test line is configured to direct the extinguishing fluid flowing through it back into a storage tank and/or an intermediate tank configured as part of the fluid supply system. This allows the extinguishing fluid flowing through the test line during the pump test run to continue to be used by the water extinguishing system.
  • the extinguishing fluid flowing through the test line is also directed into a wastewater tank and/or discharged via a wastewater line, rather than being stored.
  • the fluid diversion can also be configured to direct the extinguishing fluid flowing through it back into the storage tank and/or an intermediate tank. Alternatively, the fluid diversion can also be configured to direct the extinguishing fluid flowing through it into a wastewater tank and/or discharge it into a wastewater line and/or otherwise divert it from the piping system and not make it available to the fluid supply again.
  • the weekly pump test run is carried out manually by a trained person.
  • the test line is released by opening the opening device.
  • a starting device is then used to trigger the pump to start. This start can be automatic or manual.
  • the starting pressure which corresponds to the pressure at the time the pump starts up, is then measured and recorded, and the pump test run is continued until the normal operating parameters of the pump's drive motor are reached.
  • the test line is closed again using the opening device, and no further extinguishing fluid can enter the test line.
  • a water extinguishing system of the type mentioned above wherein the water extinguishing system comprises at least one control device configured to determine at least one parameter indicative of the cross-section of the fluid diversion and to control a pump test run of the pump based on the parameter.
  • the present invention allows the pump test run to be automated. Thus, it is no longer possible to simply start the pump test run "automatically”; instead, the entire pump test run can be performed without manual intervention. This allows a pump test run to be performed without the need for trained personnel on-site.
  • a maintenance technician can send a signal, for example via a remote connection, to the pump control unit, which ensures that the pump is started – as is already known from the prior art – for example, by a pressure drop at the pump inlet.
  • the further process can then be automated, without the need for a trained person on site. This is because, according to the present invention, the extinguishing fluid delivered by the pump during the automatic pump test run is guided via the fluid diversion, and accordingly, no opening or closing of the opening device is necessary.
  • the fluid diversion has a much smaller opening cross-section than the test line, usually at least 2%, only a very small portion of the extinguishing fluid is diverted away from the pipe system via the fluid diversion and would be available in the event of a fire. not available for firefighting. Since this is only a small portion, efficient firefighting can still be carried out.
  • the present invention is therefore based on the finding that the small proportion of extinguishing fluid that can be passed through the fluid diversion is sufficient to prevent the pump from running dry (and, for example, overheating) during the pump test run.
  • the fluid diversion line can actually carry sufficient extinguishing fluid. Due to the reduced cross-section compared to the test line, even small deposits in the fluid diversion line can prevent sufficient extinguishing fluid flow. Accordingly, the pump test run must be controlled based on whether the fluid diversion line can adequately divert the extinguishing fluid pumped by the pump during the pump test run away from the pipe system.
  • a novel control device which determines a parameter indicative of the cross-section of the fluid bypass and controls the pump test run based on this parameter.
  • the control can be designed based on the parameter in particular such that the parameter is used to determine - directly or indirectly - whether the cross-section of the fluid bypass is still large enough to supply sufficient extinguishing fluid to the pump. If this direct or indirect determination shows that sufficient extinguishing fluid can be supplied through the fluid bypass, the pump test run can be continued. If the determination shows that the extinguishing fluid flow is insufficient, the control device can be configured to abort the pump test run.
  • control device can be understood as any type of device that is quantitatively capable of controlling the pump test run of the pump based on the question of whether the cross-section of the fluid diversion is suitable and sufficient to ensure a sufficient flow of extinguishing fluid during the pump test run and thus to prevent the pump from running dry.
  • control device can be designed, in particular, as a combination of a sensor and a control unit.
  • the control unit of the control device can be arranged, in particular, on or in the vicinity of the pump.
  • control unit can be provided as a separate unit specifically designed to control the pump test run.
  • control unit can also be implemented as an additional module of the control system for automatic pump start (by reducing the pressure).
  • control unit for the pump test run according to the present invention can also be configured as part of a central device of the water extinguishing system and communicate bidirectionally with the pump via a communication unit.
  • Particularly suitable sensors for the control system are those that allow the determination of a parameter that provides information about the flow rate of the extinguishing fluid through the fluid diversion per unit of time and thus about the cross-section of the fluid diversion.
  • Such sensors can include, in particular, temperature sensors on the pump, especially at the pump outlet, since the temperature at the pump is indicative of the amount of extinguishing fluid that passes through the fluid diversion during the pump test run.
  • a vibration sensor and/or a noise sensor can be installed on the pump to measure the pump's vibrations and/or noise output during operation. If cavitation/deposits occur in the fluid bypass, the pump's vibration and/or noise output will change. These changes, compared to the values recorded during operation without cavitation/deposits, are also detected by the vibration sensor and/or the noise sensor and can thus indicate a change in the pump's operating condition and indicate that the pump test run should be aborted.
  • the sensors may also include pressure sensors that determine a pressure difference, for example, between a first and a second end of the fluid bypass, or temperature sensors that also measure a temperature and/or a temperature difference, for example, at the first and second ends of the fluid bypass and/or at the inlet and outlet of the pump.
  • a measurement of the temperature and/or temperature difference within the fluid bypass can thus, for example, allow for the detection of possible freezing of the fluid bypass, and a measurement at the pump can allow for the detection of pump overheating.
  • the sensors may also include ultrasonic sensors capable of detecting deposits within the fluid diversion and thus a reduction in the cross-section.
  • the sensors may include flow sensors configured to determine the flow rate per unit time through the fluid diversion and/or the flow rate difference, for example, between a first end and the second end of the fluid diversion.
  • the fluid bypass can be located directly on the fluid bypass and/or in the inlet or outlet lines of the fluid bypass and/or in the vicinity, on and/or inside the pump.
  • the one or more sensors of the control device transmit the sensor data to the control unit of the control device, which enables the pump operation to be controlled.
  • the control device can evaluate the sensor data and thus determine the parameter indicative of the cross-section of the fluid diversion. The control can then be carried out depending on this parameter.
  • the evaluation may include determining whether the flow rate per unit of time/the cross-section of the fluid diversion is within a predefined value range. If this is the case, it can be assumed that the pump is being supplied with sufficient extinguishing fluid. If the flow rate per unit of time/the cross-section falls below a predefined limit, it can no longer be assumed that the pump can still deliver sufficient extinguishing fluid. In this case, the control device can output a signal that interrupts the pump test run and/or prevents it from starting at all. This can prevent the pump from running dry during the test run.
  • control device can also be designed in the form of a switching device, in particular a flow switch, which switches at a certain flow rate (as a parameter indicative of the cross-section). If this flow rate is undershot, the switching device switches from an activated position to a deactivated position. In the deactivated position, the pump is deactivated.
  • the switching device can preferably be in the energetically more favorable state in the They are in the deactivation position and are shifted to the less energetically favorable state by the set flow rate. This ensures that the pump operation is interrupted in the event of a power failure.
  • the pump is not deactivated by the switch in the event of a fire.
  • This can be achieved, for example, by wiring the pump in two ways, whereby in the event of a fire, another switching device, such as a pressure switch within the pipe system, switches to an activated position and keeps the pump activated, even if the switching device switches to the deactivated position for the pump test run.

This means that the fluid diversion branches off with its first end, for example, from the distributor pipe behind the pump and thus diverts the extinguishing fluid delivered by the pump during the pump test run away from the pipe system.
  • the fluid diversion ends with its second end in a drain.
  • the second end of the fluid diversion branches off back into the fluid supply. Further configurations are possible as long as they allow the extinguishing fluid delivered by the pump during the pump test run to be diverted away from the pipe system.
