Definitions
- This invention relates to a pump arrangement utilising an impeller rotationally controlled by a motorised drive shaft for carrying out the pumping operation and more particularly to a new and improved bearing bush arrangement to rotationally constrain but allow free rotational movement of the motorised shaft when fluid is being pumped.
- bearing bush and the sealing arrangement around the motorised shaft of the pump which may also include mechanical type seals and the associated bearing lubrication system, are designed for the most part to constrain the mounted drive shaft against radial movement but at the same time allow free rotation of this motorised drive shaft whilst fluid is being pumped.
- bearings and seals are major components in pumps that regularly fail and rely upon periodic maintenance hence it would be advantageous to be avoid such conventional arrangements for bearing and seals and rely upon more seal less design that is not prone to failure and/or regular maintenance.
- a self-lubricating pump arrangement said self-lubricating pump arrangement including:
- An advantage of such an arrangement is that by utilising a portion of the exiting fluid being discharged out through the pump arrangement and redirecting it back up internally through the main housing block is that this redirected fluid can be guided up into the grooves of the bearing bush thereby implementing a self-lubricating mechanism of the fluid such that while the bearing bush is mounted so as to support radial movement of the drive shaft, the drive shaft is free to rotate during pumping as the fluid flow along the grooves provides for a lubrication system.
- this lubrication system does not form part of any mechanical seal and therefore does not require periodic inspection or regular maintenance, simplifying design, construction costs, efficiency and the appropriate fittings necessary in order to achieve the requisite pumping operation.
- the impeller member includes not only the conventional opening or openings on the first face (suction side) in order to take fluid flow from the fluid suction opening of the main housing block, but also includes on the opposing second face a plurality of openings which are able to accept the redirected fluid that is passing up through the grooves within the mounted bearing bush so as to again join the main flow as it radially exits through the series of vanes of the impeller member.
- main housing is made up of two joinable half sections.
- the self-lubricating pump arrangement further includes a sub-assembly, wherein the sub-assembly is supportable within the two joinable half sections of the main housing block.
- sub-assembly supportable within the two joinable half sections of the main housing block includes at least two sections adapted to be fastenable together to encapsulate the stator and the rotor.
- the hollow chamber is defined by spacing between an internal side of the two joinable half sections of the main housing block and an external side of the sub-assembly.
- the sub-assembly includes a first half section and a second half section, wherein the first half section and the second half section are adapted to be fastenable together to encapsulate the stator and the rotor.
- first half section includes a top surface configured to allow the impeller member to be restable thereon.
- top surface of the first half section includes a series of guide baffles that form part of the fluid flow guide arrangement.
- the bearing bush includes an upper flange.
- top surface of the first half section includes a central circular slot having a depressed collared skirt adapted for the upper flange of the bearing bush to be positionable therein.
- the generally circular impeller member has a corresponding central slot such that the drivable shaft is adapted to pass through the mounted bearing bush mounted within the front cylindrical portion of the vertical fluid flow guide arrangement to be insertable through the central slot of the impeller member with a fastening arrangement adapted then to secure the impeller member to the drivable shaft such that electrical inductive communication between the rotor and the stator provides for rotational motorised movement of the drive shaft wherein rotational movement of the drive shaft translates to rotational movement of the impeller member to provide pumping operability.
- the second half section of the sub-assembly includes a central slot at one end adapted to receive the portion of re-directed exiting fluid flow.
- the central slot includes a filter.
- first half section and the second half section of sub-assembly are configured to come together in a mating snap fit or frictional engagement in order to encapsulate the stator and the rotor.
- first half section and the second half section of the sub-assembly that encapsulates the stator and the rotor include external tab extensions assist in mounting the sub-assembly within the main housing block.
- main housing block includes two halves that can be joined together to enclosed all componentry of the pump arrangement other than an external electrical power source.
- wound stator, rotor and any other circuitry or components associated with the electrical inductive operation of the pump are fully encapsulated in appropriate insulating material.
- the self-lubricating pump arrangement (10) includes a main housing block made up of two joinable halves (12) and (14) which as best seen in Figure 2 are joinable together to encapsulate the remaining components and elements of the self-lubricating arrangement (10).
- main housing block Mounted internally within the two joinable halves (12) and (14) of main housing block is the sub-assembly of the vertical fluid flow guide arrangement which in itself is made up in the preferred embodiment of two generally cylindrical half portions (16) and (18) which again as best seen in Figure 2 are able to be snap fitted together in order to encapsulate and contain therein the wound stator (26) and the rotor (24) positionable within the wound stator (26).
- the sub-assembly of the vertical fluid flow guide arrangement made up of the two halves (16) and (18) also encapsulates the printed circuit-board (33) and the related electrical and electronic componentry which work in combination with the insulated power connection shown as (60) in Figure 2 to provide the requisite electrical inductive communication between the rotor (24) configured within the stator (26) such that induced rotation of the rotor (24) results in corresponding rotation of the drive shaft (28) extending out from the rotor (24).
- the drive shaft (28) is appropriately constrained against radial movement by virtue of the mounted bearing bush (22) which as best seen in Figure 2 is able to rest within the defined slot (66) of the half portion (18) wherein a depressed collared ring shown as (67) allows the flange (75) of the bearing bush (22) to be positionable therein.
- the drive shaft (28) is able to pass through the defined opening (66) and where the distal end (7) of the drive shaft (28) is able to engage a fastener (30) by virtue of the corresponding slot (91) passing through the impeller member (20) so as to secure the impeller member (20) to the drive shaft (28).
- Support ring (32) also assist in positioning the impeller (20) within the main housing block.
- the impeller member (20) is mounted to the drive shaft (28) such that it is positioned to take fluid from the fluid suction opening (51) of the half section (14) of the main housing block whereupon rotation of the impeller member (20) as the drive shaft (28) is sent into driven rotation by the electrically induced communication between the rotor (24) and the wound stator (26) fluid may be sucked through the opening (92) of the impeller member (20) upon the upper face (87) of the impeller member (20) wherein once the fluid passes through the opening (92) it is then able to engage the series of internal vanes (46) so that fluid shown by way of the thicker arrows (57) in Figure 2 is able to be sucked in through the opening (92) of the impeller member (20) to radially exit through the side (94) of the impeller (20) and wherein baffles (25) that include a section (27) on the top surface (23) of the sub-assembly end portion (18) are configured to take fluid radially exiting from the side (94) of the impeller member (20
- the main flow of fluid (57) during operational pumping is designed to suck fluid from the opening (51) to direct it through the opening (92) of the impeller member (20) where it can engage the circulating internal vanes (46) to increase velocity of the radially exiting fluid so as to then be guided down the internal chamber (44) between the main housing block halves (12) and (14) and the enclosed sub-assembly (16) and (18) which is housing the motorised pump componentry.
- the fluid again shown by way of arrows (57) is able to exit the main housing block (12) and (14) through the fluid discharge opening (53).
- the defined slot (40) which includes at the main opening filter (42) allows a redirected flow shown by way of arrow (80b) to be introduced into the encapsulated hollow spacing (101) of the confines of the end portion (16) of the sub-assembly enclosing the motor of the pump arrangement.
- the actual electrical and electronic componentry of the printed circuit-board (33), rotor (24) and wound stator (26) are all appropriately insulated such that the introduction of the self lubrication fluid (80b) entering the hollow chamber (101) does not have any adverse effect on the integrity of operation of the electrical and electronic componentry for the pump arrangement.
- the redirected lubrication flow (80b) is directed into opening (54) shown by way of the arrow (80c) and as best seen when reviewing Figure 2 but also Figures 3a and 3b , as the bearing bush (22) along its main longitudinal column (70) includes a series of appropriately aligned open internal grooves (71), (72) and (73), this allows the redirected lubrication flow to pass up through these internal groove openings (71), (72) and (73) such that when the bearing bush (22) constrains the radial movement of the drive shaft (28) it still allows for free lubricated rotational movement of the drive shaft when fluid is being pumped due to the unique arrangement of redirecting a small portion of the main fluid flow (57) back into the sub assembly (16) and (18) so that it acts as a lubrication thereby preventing the bearing bush from being sacrificially slowly disintegrated which would generally be the case with a conventional bearing bush which slowly withers away during the slight frictional contact as the drive shaft is constrained against radial movement but allowed for
- the redirected lubricating fluid flow is able to absorb heat generated by the motorised componentry encapsulated within the sub-assembly made up of the two halves (16) and (18) where once it enters the impeller member (20) and re-joins the main flow can then be discharged the heat out through the fluid discharge opening (53) of the main housing block half of the self-lubricating pump arrangement (10).
- the bearing bush (22) shows three internal groove openings (71), (72) and (73) wherein there can be a variety of arrangements for balanced flow of the re-directed fluid there along the internal side (77) of the bearing bush in order to establish the requisite self-lubricating system.
- sub-assembly which is made up of the half portions (16) and (18) can further include brackets or external tabs and the like which will allow the sub-assembly to be conveniently mounted and enclosed therein the main housing block when the two external joinable halves (12) and (14) of the main housing block are brought together as seen in Figure 2 .
- this invention also is designed to allow convenient assembly and disassembly of the pump arrangement in order to inspect and maintain any ongoing maintenance and the like that may be required during ongoing operation of the self-lubricating pump arrangement.
