Embodiments of the present invention relate to a pump system that allows for a large volume of water flow. In particular, embodiments of the present invention relate to a pump system using a main host pump supplied by one or more submersible mobile supply pumps.

There are many uses for pump systems that carry large volumes of water flow, including urban and industrial fire extinguishing devices, drinking water supplies, emergency rescue and / or other disaster relief needs. This example requires a large volume of water at large flow rates, such as 5000 gallons per minute or more. Typical water sources include lakes, rivers, and lays. Typically, however, the water source cannot be located in or accessible to the area where water is needed. For example, it is not uncommon for the required area to be far from the nearest source (ie miles). Thus, it is desirable to have a pump system designed to withdraw water from long distances and to run large volumes of water over long distances.

Many current devices use conventional suction / discharge supply pumps, such as fire pump systems. However, such devices present the disadvantage that the suction lift and the distance they can be used from the available water source are limited. Also, such devices are limited in their vertical lift capacity or in the ability to pull water from a source that is lower than the device. Most current designs can only drift water into their pumps from water sources that are lower than 10-12 feet below their suction. While such devices may be suitable for their purposes, these drawbacks are directed to an improved pump system that can carry large volumes of water over long distances and also have an improved vertical lift to access lower water sources. Indicates that there is a demand.

The pump system 10b also includes a supply hose 72b and a hydraulic hose 74b connected in a similar shape to the satellite feed pump 60b. Similar to the pump system 10, the feed pump 60b is supported by the strainer carriage 61b. The feed pump 60b is deployed to the water source 82b. 6 shows a good working distance D between the water source 82 and the pump system 10b. Preferably, the working distance is about 150 feet. The shape of FIG. 6 shows the distance E for allowing the pump system 10b to operate from the level on the surface of the water source 82 to the level of the deployed pump system 10b. Preferably, the working distance is about 50 feet, which provides a vertical lift of up to about 50 feet. Thus, while the satellite pump carries the water flow to the main pump, the pump system 10b and the main pump can be located on a hill, cliff or high dock.

6 shows a discharge hose 76b used to carry water flow from the main pump fed from the satellite feed pump 60b and feed hose 72b. The discharge hose 76b may be supplied to a fire extinguishing nozzle 100, such as any desired final destination 85 and / or a high flow fire extinguishing nozzle. The final destination can be any area where water is needed, such as drinking water use, urban and industrial fire extinguishing, or disaster relief areas.

In another preferred embodiment, multiple host pump modules may be incorporated. As schematically shown in FIG. 6, an embodiment of the present invention may incorporate an additional pump system 10 'acting solely as a boost pump. The additional pump system 10 'can be formed in series as a plurality of boost pumps. Preferably, the series of boost pumps are spaced apart by X distances, where X represents a number of miles between each pump system 10 '.

In addition, embodiments of the present invention may provide a flow rate based direct provisioning system (not shown). The ratio system can be the basis for flow measurement. The pump system can be operated using additional feed (i.e. foam) that is pumped, such as incorporating a tanker with a transport pump. The bulk supply of additives may be pumped from the bulk container into the suction side of the pump system. The flow meter may indicate the flow rate of the solution present in the pump as well as the flow rate of the additive entering the suction manifold of the pump system. These flow ratios can then be compared to determine the injection percentage achieved. The injection percentage can be increased or decreased by adjusting the rpm of the transport pump supplying additives to the pump system. Adjustments can be made based on the readings shown on the flow meter output.

In the embodiment shown only in Figs. 5 and 6, the embodiment of the present invention can provide the following sequence of operations. The pump system can be deployed by rolling off the haul truck using a cable drag deployment system. The door is opened to the rear of the container where two submersible pumps are stored. When used, the door on one side of the container is opened to provide access to the suction and discharge connections. The two submersible satellite feed pumps are rolled out of the end bay down ramp, which can be pulled out from the bottom of the container. A quick connect recovery cable can be attached to each submersible pump. Each pump is rolled at the edge of the water where the 8 inch water supply hose is connected to the discharge connection of each submersible satellite pump. The 8 inch supply hose is then deployed from the satellite pump and connected to the main pump suction manifold connection. The suspended submersible satellite pump is then rolled into water. A pontoon system is then used to float the pump to a position in the water. The 12 inch discharge hose of the main pump can be developed in series (using the series in FIG. 6) from the discharge connection of the pump system to the next device. The device may be a boost pump or a large capacity fire extinguishing nozzle or other pumping system that serves as the final destination.

After the set-up of the system is completed, pumping can proceed. The sequence of these operations is as follows. (1) Start the underwater hydraulic pump driver to set up the rpm to about 1900 rpm. This drives the servohydraulic pump driver, which can sense the main pump inlet pressure and also provides the necessary submersible satellite pump to maintain the appropriate (ie 5 to 15 psi) water pressure at the main pump inlet. Speed up or slow down. The hydraulic pump can generate appropriate hydraulic power (ie 50 GPM at 5000 psi) in each submersible satellite pump. The hydraulic flow and pressure will drive the submersible satellite pump to generate more than 2500 GPM of water flow to the main pump. Thus, the hydraulic hose line can be sized to allow linear deployment of about 150 feet. (2) Switch the hydraulic pump manual control to the "ON" position. Thus, this may incorporate a hydraulic pump that presses a hydraulic motor fixed to the floating submersible satellite pump. The float pump may begin to develop pressure and pump water through the 8 inch supply hose to the main pump. (3) Read the pressure gauge on the pump panel to verify a positive water pressure of at least 10 psi at the main pump inlet. (4) Switch the hydraulic pump manual operation to the "automatic" position. This may allow the hydraulic control system to track the main pump inlet pressure and automatically increase or decrease the submersible pump speed needed to continuously feed the main pump through its range. (5) Start the main pump and start pumping the discharge device at the desired pressure. (6) Set electrical engine control to automatic mode. This may begin by the electrical engine control system tracking the main pump discharge pressure, thereby automatically increasing or decreasing the engine speed required to maintain the discharge continuously.

More preferably, an exemplary embodiment is designed such that the satellite pump can pump water into the main pump prior to starting the main pump. For example, the second engine can be used to drive the satellite pump independent of the first engine and the main pump. The satellite pump may supply water to the main pump to prepare the main pump. This minimizes the possibility that the main pump is "dried dry" (ie, run without sufficient water). Driving in dry conditions is a good advice for pump manufacturers, as it can cause damage to the main pump.

7-9, an exemplary embodiment of a pump system 200 is shown. As shown in FIGS. 7A-7F, the system 200 includes a container 15 ′ similar to the system 10 described above. However, the system 200 differs in that the system 200 does not include a main pump or a first engine to drive the main pump. Instead, as shown in FIGS. 8A-8D and 9A and 9B, the system 200 includes only the satellite pump 60 'and the engine 68' to drive the satellite pump 60 '. do.

As shown in FIG. 10, satellite pump 60 ′ of system 200 may be deployed at water source 82c to supply water to a separate boost pump 250. The separate additive injection module 260 may be connected to the boost pump 250 to inject the additive into the water supply.

11A and 11B, another embodiment pump system 300 is shown. Pump system 300 is similar to system 200 except that system 300 includes two satellite pumps 60 '. As shown in FIG. 12, the satellite pump 60 ′ may supply water from the water source to the separate boost pump 350, respectively. Again, boost pump 350 may supply water to mobile fire extinguishing carrier 370 through manifold 360. Additional description of an exemplary embodiment of the manifold 360 and mobile fire extinguishing carrier device 370, filed August 26, 2004, is entitled "High Flow Mobile Fire Extinguishing System" (High Flow Mobile Fire). Fighting System), the entire contents of which are described in US Patent Application No. 10 / 926,736, which is incorporated herein by reference.

Referring next to FIG. 13, as shown in US patent application Ser. No. 10 / 926,736, a satellite pump 60 ′ of system 300 is shown connected to a water pump 450. Again, water pump 450 is connected to mobile fire extinguishing carrier 370 using manifold 360.

System 200 and system 300 may be used by the satellite pump (s) to supply water to one or more separate main pumps in various shapes. The system 10 is similar (without using the main pump 50 and the first engine 40) through the use of the second engine 68 and the satellite pump 60 to supply water to a separate main pump. Can be used in a way.

Embodiments of the present invention provide many advantages over existing pump systems. Using a satellite feed pump to supply the main pump has the following advantages. The operator can draw water to the main pump up to 200 feet and 15 times farther than that normally achieved with a standard suction hose supply setup. The satellite feed pump increases vertical lift capability by up to 50 feet and up to five times the typical drift capability of a typical fire extinguishing system.

This design may allow for an increase in the number and type of water supply reservoirs or sources that can be tapped at one time to supply water for pumping. The host pump can be located farther away from the water source, providing the capacity of a large capacity flow without significant degradation in hydraulic efficiency and power.

Multiple host pumps can be set up in series for non-limiting pumping distances. Embodiments of the present invention may use large diameter fire extinguishing hoses that may be suitable for use with drinking water.

The host pump also incorporates a self-contained hydraulic flow and pressure control system that protects the system from loss of control, damage to itself or loss of flow capacity. Embodiments of the present invention include a dual engine system, one engine for a host pump and the other engine for a satellite feed pump. This shape can ensure that the host pump does not operate in a dry state. This shape also allows adaptability in the use of the system. Also in this configuration, the separate hydraulic pump driver can operate any other parasitic device that can be used to provide water to the main pump as well as to prepare for preparation. This shape allows the pump system to supply water to the main pump or another main pump. This also allows the pump system to simply operate as a boost pump in series with multiple pump systems. When the boost pump is in operation, the pump system does not require the use of a submersible satellite feed pump. Thus, the satellite feed pump can be stored when not in use.

Embodiments of the present invention provide manual and automatic control of hydraulic hydrostatic drive systems for submersible feed pumps to allow for non-limiting setup changes.

In addition, embodiments of the present invention provide an electrically controlled retention system for a main host pump that is designed to include a selection for automatic addition ratios. The container structure allows for complex capabilities and system modularity such as roll off, hook arm and drag capability of cables, and interconnection with other connection modules.

Fluids used in the system, such as additives, hydraulic and cooling fluids, are considered and selected according to their environmental requirements. The pump system also includes a drip containment device to prevent module fluid from entering the environment.

Although exemplary embodiments of the invention have been described, changes, modifications, and the like can be made by those skilled in the art. Such changes and modifications will be included within the scope of the present invention.
