Definitions

  • the current patent request is for a modular pump with greater particle intake capacity, with a variety of possible uses, but used most specifically in irrigation systems, basic sanitation, and for pumping industrial fluids.
  • the underwater pumps currently used in fluid pumping systems present numerous maintenance issues, because they don't allow the passage of long fibers.
  • the pumps are installed in holding tanks at each level, according to need. Due to the constant elevations that exist in the tubing path, it is necessary to build several holding tanks and install these pumps to supply an entire area, whether it's an industrial area or a city's entire basic sanitation network.
  • Residue that was discarded into the tubing can often be found stored in these holding tanks. Due to the fiber size of these particles, the pump opening is frequently blocked, causing it to no longer pump effectively. Also, due to the type of particles found in these collection boxes, bad smells and the production of methane gas can occur. This gas not only produces an unpleasant sensation, but can also cause explosions if the methane comes into contact with anything ignescent.
  • ABS and FLYGT companies developed and made pumps that operate in holding tanks. These pumps operate in a vertical position and have a special impeller with two larger outlets that allow the entry of larger particles. However, due to the way they are built; these particles normally get stuck in the volute and end up blocking the passage of fluid and thus blocking fluid entry into the volute. Also, the pumps made by these previously mentioned companies are pumps with dry electric motors that are protected by a mechanical seal system. This type of construction can't function with elevated pressure levels, because the liquid pressure would burst the seal, allowing water to enter the motor, damaging the electric coil (burning the motor) and the bearings, causing the pump to stop.
  • the objective of this invention is to supply a modular pump ( 1 ) that can be installed in a series and has a special volute and impeller, capable of allowing large particles to enter without damaging the system.
  • the modular pump ( 1 ) proposed here is made up of an opening where there is a volute ( 11 ) and a impeller ( 12 ) that are followed by an motor shaft ( 15 ) of the motor ( 14 ), and a centrifuge ( 13 ) connected to the motor shaft ( 15 ).
  • FIG. 1 represents a frontal cut section view of one configuration of the modular pump ( 1 ), where we can observe the location of the impeller ( 12 ) of the centrifuge ( 13 ), and the motor ( 14 ).
  • FIG. 2 represents a detailed view of the centrifuge ( 13 ) where we can observe the orifices. ( 131 ).
  • FIG. 3 represents a perspective view of the impeller ( 12 ) where we can observe the location of both exits ( 122 ) and both tabs ( 123 );
  • FIG. 4 represents an overhead view of the impeller ( 12 ) where we can observe the location of the tabs ( 123 );
  • FIG. 5 represents a perspective view of another configuration of the modular pump ( 1 ) in a vertical direction
  • FIG. 6 represents a frontal cut section view of another configuration of the modular pump ( 1 ), where we can observe the location of the impeller ( 12 ) and of the centrifuge ( 13 ) in a vertical direction.
  • This modular pump ( 1 ) has a volute ( 11 ) and a impeller ( 12 ) with a design shape with rounded edges, which allows for larger particle such as diapers, sanitary napkins, or any other long fiber to pass through the impeller ( 12 ), while in use, without getting stuck.
  • the impeller ( 12 ) has a fluid entrance attached to the pump entrance through the volute ( 11 ), and in its perimeter has two exits ( 122 ). Observing the impeller in isolation, we notice that between the exits are two tabs ( 123 ). Due to the tabs ( 123 ) the centrifugal force that arises during the movement of the impeller ( 12 ) does not allow a layer of fluid to develop. This fluid normally contains particles that would be abrasive to the body of the impeller ( 12 ).
  • the centrifuge ( 13 ) with the help of centrifugal force, expels the sand in the fluid out the orifices present along the body of the centrifuge. This keeps the pump from getting worn down all the way to the pump wear out rings.
  • this modular pump In the main configuration of this modular pump ( 1 ) the pump works horizontally, this way the fluid enters radially in relation to the pump. Under this configuration, the motor of the pump was relocated and rather than being in the center of the pump it is above the center of the pump ( 1 ), so that the fluid and the particles with long fibers pass freely, directly below the motor ( 14 ).
  • the modular pump ( 1 ) is mounted in connection with the tubing, with no special construction necessary such as holding tanks, even though the modular pumps ( 1 ) may be mounted in a series if necessary.
  • this modular pump ( 1 ) we have a pump that functions vertically. In this case, the fluid enters the pump in the vertical position, but it does not cross the pump. In this case, it is not necessary to relocate the motor ( 14 ) because the fluid exits from a side opening.
