- FIG. 6 schematically illustrates a pump system 10b in use. Similar components as Figure 5 are denoted with the same numbers and including the suffix "b.”
- the pump system 10b also includes supply hoses 72b and hydraulic hoses 74b connected in a similar configuration with satellite supply pumps 60b. Similar to pump system 10, the supply pumps 60b are carried in strainer carriages 61b. The supply pumps 60b are deployed in a water source 82b.
- Figure 6 illustrates a preferred operating distance D between the water source 82 and the pump system 10b. Preferably, the operating distance D is at about 150 feet.
- the configuration in Figure 6 shows an elevational distance E allowing the pump system 10b to operate from a level on a surface of the water source 82 to a level that the pump system 10b is disposed.
- the elevational operating distance is about 50 feet, providing a vertical lift of about and up to 50 feet.
- the pump system 10b and main pump may be located on a hill, cliff or high dock, while the satellite pumps may deliver water flow to the main pump.
- FIG. 6 shows discharge hoses 76b that may be used for delivering water flow from the main pump supplied from the satellite supply pumps 60b and supply hoses 72b.
- the discharge hoses 76b may supply to any desired end destination 85 and/or to a fire fighting nozzle 100, such as a large flow firefighting nozzle.
- An end destination may be any area needing water, such as for potable water use, municipal and industrial firefighting, or a disaster relief area.
- a plurality of host pump modules may be incorporated.
- embodiments of the present invention may incorporate additional pump systems 10' operating solely as boost pumps.
- the additional pump systems 10' may be configured in series as a plurality of boost pumps.
- the series of boost pumps are spaced X distance apart, where X denotes a number of miles between each pump system 10'.
- Embodiments of the present invention may also provide a flow rate based direct injection proportioning system (not shown).
- a proportioning system may be flow measurement based.
- the pump system may be operated using a pumped additive supply (e.g., foam), such as by incorporating a tanker having transfer pump.
- a pumped additive supply e.g., foam
- a bulk supply of additive may be pumped from a bulk container into the suction side of the pump system.
- Flow meters may display flow rates of the solution exiting the pump as well as the flow rate of the additive entering the suction manifold of the pump system. These flow rates may then be compared to determine the percent injection that is being achieved. The percent injection may be increased or decreased by adjusting the rpm of the transfer pump that is supplying additive to the pump system. Adjustments may be made based on readings shown on flow meter outputs.
- the pump system may be deployed by rolling off a delivery truck using a cable drag deployment system. Doors are opened at the rear of the container where two submersible pumps are stored. Doors, when used, on each side of the container are opened up to offer access to suction and discharge connections.
- the two submersible satellite supply pumps are rolled out of the end bays down ramps that may be pulled out from the floor of the container.
- a quick connect retrieval cable can be attached to each submersible pump. Each pump is rolled to the waters edge where an 8 inch water supply hose is then connected to the discharge connection of each submersible satellite pump.
- the 8 inch supply hoses are then deployed from the satellite pumps and connected to the main pump suction manifold connections.
- the floating submersible satellite pumps are then rolled into the water.
- a pontoon system may then be used to float the pumps into position in the water.
- the main pump 12 inch discharge hose may be deployed from the discharge connections of the pump system to the next device in line (in line use of Figure 6). This device could be a large flow firefighting nozzle or another pumping system operating as a boost pump or end destination.
- the sequence of operation is as follows. (1) Start submersible hydraulic pump driver and set rpm to about 1900 rpm. This will drive a Servo hydraulic pump system that can sense a main pump inlet pressure and speed up or slow down the submersible satellite pumps as necessary to maintain adequate (e.g., 5 to 15 psi) water pressure at the main pump inlet.
- the hydraulic pump can develop adequate (e.g., 50 GPM at 5000 psi) hydraulic power at each submersible satellite pump.
- This hydraulic flow and pressure shall drive the submersible satellite pumps to create a 2500 GPM or greater water flow up to the main pump.
- the hydraulic hose lines may be sized accordingly to allow for about a 150 foot linear deployment.
- example embodiments are designed so that the satellite pumps pump water into the main pump before the main pump is started.
- the second engine can be used to drive the satellite pumps independently of the first engine and main pump.
- the satellite pumps can deliver water to the main pump to prime the main pump. This minimizes the possibility of the main pump "running dry” (i.e., running without sufficient water). Running dry is a condition that is advised against by pump manufacturers, as it may result in damage to the main pump.
- system 200 includes a container 15' that is similar to system 10 described above.
- System 200 differs, however, in that system 200 does not include a main pump or first engine to drive the main pump. Instead, as shown in Figures 8A-8D and 9A-9B, system 200 includes only a satellite pump 60' and engine 68' to drive satellite pump 60'.
- satellite pump 60' of system 200 can be deployed in a water source 82c to supply water to a separate boost pump 250.
- a separate additive injection module 260 can also be coupled to boost pump 250 to inject an additive into the water supply.
- Pump system 300 is similar to system 200, except that system 300 includes two satellite pumps 60'. As shown in Figure 12, satellite pumps 60' can each supply water from a water source 82d to a separate boost pumps 350. Boost pumps 350 can, in turn, supply water to a mobile fire fighting delivery device 370 through a manifold 360. Additional details regarding example embodiments of manifold 360 and mobile fire fighting delivery device 370 can be found in U.S. Patent Application Serial No. 10/926,736, filed on August 26, 2004 and entitled "High Flow Mobile Fire Fighting System," the entirety of which is hereby incorporated by reference.
- Satellite pumps 60' of system 300 are shown connected to a water pump 450, as described in U.S. Patent Application Serial No. 10/926,736.
- Water pump 450 is, in turn, coupled to mobile fire fighting delivery device 370 using manifold 360.
- Systems 200 and 300 are advantageous in that the satellite pump(s) can be used to provide water to one or more separate main pumps in a variety of configurations.
- System 10 can be utilized in a similar manner through use of second engine 68 and satellite pumps 60 (without the use of main pump 50 and first engine 40) to deliver water to a separate main pump.
- Embodiments of the present invention provide many advantages over existing pump systems.
- Use of the satellite supply pumps to feed the main pump has the following benefits.
- An operator can draw water to the main pump up to 200 feet and 15 times farther away than could normally be accomplished with a standard suction hose supply setup.
- the satellite supply pumps increase the vertical lift capability up to 50 feet and up to 5 times greater than normal draft capabilities of a typical fire apparatus.
- the design may enable an increase in the number and type of water supply reservoirs or sources that can be tapped at one time to provide water for pumping.
- the host pump can be placed much further away from the water source and still provide large flow capability without significant degradation in hydraulic efficiency and output.
- a plurality of host pumps can be set up in series for unlimited pumping distances.
- Embodiments of the present invention can utilize a large diameter fire fighting attack hose that may be suitable for potable water use.
- the host pump unit also incorporates a self-contained hydraulic flow and pressure control system that prevents the system from losing control, damaging itself or losing flow capability.
- Embodiments of the present invention include a dual engine system, one engine for the host pump and another engine for the satellite supply pumps. This configuration can help ensure that the host pump does not operate in a dry condition. This configuration also allows for flexibility in the use of the system. Further, a separate hydraulic pump driver, in this fashion, can operate all other parasitic devices that may be used as well as carry its primary function of priming and supplying water to the main pump. This feature allows the pump system to supply water to either the main pump or an alternate main pump. It also allows the pump system to simply operate as a boost pump in series with a plurality of pump systems. Thus, the water and/or additive solution may be pumped over long distances. When in this boost pump operation, the pump system does not require the use of the submersible satellite supply pumps. Thus the satellite supply pumps can be stowed while not in use.
- Embodiments of the present invention provide manual and automatic control of a hydrostatic drive system for the submersible supply pumps allowing for unlimited set up variations.
- embodiments of the present invention provide an electronically controlled management system for the main host pump, which is designed to include an option for automatic additive proportioning.
- the container structure allows for an inter modal capability and system modularity, such as roll off, hook arm and cable drag capabilities and interconnectability with other connecting modules.
- Fluids used in the system such as additives, hydraulic and coolant fluids are considered and selected according to their environmental impact.
- the pump system may also include drip containment devices to prevent module fluids from entering the environment.
