Definitions

  • This invention relates to pump arrangements. Particularly, but not exclusively, the invention relates to pump arrangements used for the refueling of hydrocarbon fueled machinery that have movement cost implications. Such machinery is typically refueled on site from mobile storage vessels such as barrels or bowsers that are carried by truck or other vehicle.
  • Examples of such machinery may include construction, agricultural or industrial machinery.
  • Off road vehicles such as diggers, cranes, and other excavation vehicles are generally refueled on site. These are typically, but not exclusively diesel vehicles. Boats and other marine equipment also have refueling mobility issues.
  • the machinery is typically provided with a pump which is mounted on the machinery, usually in a toolbox.
  • a flexible hose is stored in a tool compartment, and this is coupled at one end to the pump inlet, whereas the hose free end is placed in the mobile container.
  • the outlet to the pump may be permanently connected to the machinery's fuel tank.
  • the free end of the hose has a strainer, which is immersed in the diesel fuel within the container.
  • a pump arrangement for pumping liquid from a reservoir of liquid to a vehicle storage tank, the pump arrangement comprising a hose having a first end adapted to be releasably coupled to the vehicle storage tank, and a pump mounted at the second end of the hose, the pump being adapted to be temporarily immersed in the reservoir of liquid.
  • This arrangement provides the pump for refueling or refilling of another tank as part of the refueling/refilling hose.
  • This hose and pump assembly can be stored anywhere, either on or off a vehicle, and when stored on the vehicle, it can be stored in an area that does not need to be adjacent the fuel/water tank. This enables space savings for the parts of the vehicle which have the most critical space demands.
  • the pump may comprise a centrifugal pump, which is a well known reliable pump which can be made with no elastomeric moving parts, and is particularly suitable for the transfer of hydrocarbon fuels due to its safe dry running capability.
  • the pump is powered by a fully submersible electric motor which may be cooled directly from the fluid being pumped.
  • the pump is preferably fitted within a primarily cylindrical housing at the end of the hose, and this is sized to fit into the opening in a standard fuel barrel.
  • the housing can have an outer diameter preferably less than 60 mm, and particularly less than a 2 inch (50 mm) BSP (British Standard Pipe) female thread.
  • a strainer can be provided at the pump inlet.
  • a flow straightener can also be provided at the pump inlet and these two may be combined.
  • the pump preferably comprises an electric motor, and electrical supply wires are provided through the inside of the hose which protects them from rough handling and abuse.
  • a non return valve can be provided at the pump outlet. To aid priming, a valve can be incorporated into the pump to allow air to be expelled from inside the pump before use, but to restrict fluid loss during pump operation.
  • the pump and hose may be de-coupled (including electrical connections) to aid serviceability.
  • a shut off device can be provided for shutting off power to the pump based on the pump drive conditions.
  • the pump can comprise an electric motor, and the shut off device shuts off power to the pump when the current drawn by the pump motor is below a threshold level. This can be used to detect when the pump is running dry, or if there is a blockage in the hose.
  • the invention also provides a vehicle having a pump arrangement of the invention.
  • vehicle may comprise a fuel tank with the pump separate or attached to it.
  • the invention also provides a method of refilling a storage tank of a vehicle, comprising:
  • FIG. 1 shows a pump arrangement of the invention
  • FIG. 2 shows a vehicle and a mobile tank to which the invention can be applied
  • FIG. 3 shows how the cable arrangement is installed into the hose
  • FIG. 4 shows a modification to the pump arrangement.
  • a first example of the invention relates to machinery such as vehicles, which are refuelled remotely from a fixed refuelling centre, typically using fuel stored in barrels, bowsers (pumps for dispensing fuel) or other containers driven to the site of the machinery.
  • the machinery may have a tank that holds 1000 liters (250 gallons) of diesel fuel.
  • a pump is mounted near the fuel tank of the machinery which is to be filled and connected via a hose.
  • a hose is connected to the pump and leads to the external fuel container for refueling purposes.
  • a first example of the invention provides a refueling pump arrangement 30 ( FIG. 2 ) comprising a refueling hose 1 connected to or inserted into the machinery fuel storage tank 13 , and a pump 2 mounted at the free end of the hose.
  • the refueling pump 2 may be stored in the machinery cab C and the hose is typically stored in a tool kit, either on or off the vehicle, when not in use.
  • the hose can be stored in an area 34 that does not need to be adjacent to the fuel tank.
  • FIG. 1 shows a pump arrangement 30 that includes a hose 1 for submersion into a mobile container such as a fuel barrel 12 .
  • a mobile container such as a fuel barrel 12 .
  • the pump arrangement also includes a pump 2 at the end of the hose.
  • the pump 2 lies in a primarily cylindrical housing 6 which houses an electric motor 3 , a pump element 4 such as centrifugal vanes and a non-return valve 5 .
  • a filter can also be incorporated into the pump.
  • a flow straightener can also be added to the pump inlet 7 , and these two items can be combined.
  • An air check valve can also be incorporated into the pump above the pump element or set 4 .
  • the pump element 4 comprises a centrifugal element for a centrifugal pump, which is a well known pump suitable for fuel pumping.
  • FIG. 2 shows one example of the type of machinery which may use the pump arrangement of the invention, and shows excavation machinery M.
  • the pump housing 6 is designed to fit into the opening 36 in a standard fuel barrel 12 .
  • the housing can have an outer diameter of 60 mm.
  • a control panel 10 is used to control the refueling operation, once the refueling pump arrangement has been connected to the inlet 22 of the fuel tank 13 .
  • This connection provides both fluid and electrical connection of the refueling pump arrangement to the fuel tank and control panel 10 .
  • the pump housing 2 is submerged in fuel 11 in the barrel 12 .
  • the control panel 10 can provide automated control of the pump to provide the required delivery flow rates and to cease operation of the pump when the tank 13 is full or when the container 12 is empty.
  • the refueling pump arrangement including the hose and pump can be stored as part of the tool kit of the vehicle, and this can be stored anywhere on or off the vehicle.
  • FIG. 3 shows how the electricity supply cables 14 can be provided to the pump through the hose 1 , although it may instead run attached to an outer wall of the hose.
  • FIG. 4 shows a system with an additional safety shut off device 20 that is added to the automated control mentioned above, and which controls the power supply to the pump 2 .
  • This device can be used to prevent the pump running when the pump is not immersed in fluid, for example because all fluid has been pumped or the pump has not been inserted deeply enough into the tank 12 . This prevents overheating and can also save energy.
  • the load on the pump is directly related to the material being pumped.
  • the current drawn by the pump motor can be measured and used as an indicator of whether the pump is immersed in liquid or if it is in a gas (e.g. air).
  • the motor may draw 8 to 9 Amps when pumping liquid, but draw 4 Amps when in air.
  • a current flow of 5 Amps or less provides an indication that the pump is running dry, there are air bubbles in the pump, or there is no flow because the hose is blocked.
  • a further switch 22 can be installed in the tank 13 to be filled, to provide an indication that the tank 13 is full to switch off the pump. This can be in the form of a normally closed float switch.
  • the user control panel ( 10 of FIG. 2 ) forms part of the safety device 20 of FIG. 4 , and can simply comprise an on and an off button 24 , 26 , as shown schematically in FIG. 4 .
  • the pump can only be turned on when there is sufficient current, and current overload can be protected by a fuse.
  • the safety device will switch off whenever the tank being filled is full or the tank being emptied is empty.
  • the manual off switch provides an extra user controlled shut off capability.
  • the pump arrangement is for refueling, but the same arrangement may be used for pumping other liquids.
  • the pump arrangement can be used to pump water from a stream/creek to a water storage tank. This may be of interest for many different types of agricultural machinery such as vehicles.
  • the arrangement of the invention provides the pump at the free end of the hose, namely as a portable fitting which is immersed in the liquid to be pumped on site.
