Definitions

  • This invention relates to machines for transferring energy, and more particularly to such machines wherein the energy transfer involves a fluid medium.
  • This invention is primarily concerned with the transfer of energy either to or from the iluid by a moving member.
  • This invention is further concerned with fluid handling machines wherein the relative fluid motion upon appropriate active working surfaces accomplishes the transfer of energy.
  • This invention lits into the general category of other successful fluid handling machines near the rotary and turbomachine category.
  • the categorization is accomplished by comparing a specific diameter and a specific speed of such lluid handling machines.
  • the piston type lluid handling machines have relatively large specific diameters and relatively low specific speeds with an etliciency factor approaching 80%.
  • the rotary type machines such as roots blowers or vane pumps or motors, have much smaller specific diameters and much higher specific speeds than piston type machines, and have an efficiency factor of approximately 60%.
  • the terms specific diameter and speciilc speed are used in their well-known meaning to those familiar with the turbine art.
  • T urbomachines comprise a third broad category of lluid handling machines. They have larger specific speeds than rotary type turbomachines and these turbomachines have an elllciency factor of approximately 80%.
  • Turbomachines in general, consist of radial, axial and mixed llow types of machines.
  • This invention provides a fluid handling machine which has a range of specific diameters and specific speeds iitting between the conventional turbomachines and the rotary machines, and overlapping considerably into the category of rotary machines.
  • This invention occupies a useful application area which previously has been unsuccessfully occupied by lluid handling machines commonly called drag pumps and drag turbines. These prior art fluid handling machines have been characterized by relatively low efficiency factors. The eiliciency factor with which these machines have been known to operate has been approximately 40%, with the best alleged performance for a single drag type pump or friction pump, as it is sometimes so referred to, being approximately 50%. However, normal efficiencies of this Vtype of machine are 40% or lower.
  • This invention provides a fluid handling machine for the transfer of energy, which machine has an elliciency factor of between 65% and 70% with a potential for even better efficiencies over a relatively broad operating range.
  • This invention has as one of its advantages a much higher peak elliciency. It has a further advantage that it has a sizable region of operating conditions such as speed, llow and pressure ratios over which it will operate with a high etliciency.
  • a further advantage of this invention is that it will produce for a given tip speed of the active working surfaces a much higher head than ⁇ prior art machines, wherein head is defined as the energy transfer per pound of lluid.
  • FIG. l is a representation of one embodiment of this invention.
  • FIG. 2 is a sectional view of a plane passing through the line 2--2 of FIG. l.
  • FIGS. 3a and 3b are representations of other embodiments of this invention taken through a section similar to but not taken at section 3-3 of FIG. l.
  • FIG. l there is illustrated a plurality of driven means or shafts 10. At least one of these shafts 10 may be connected to a source of energy or to an output, depending upon whether or not the device of FIG. l is being used to transfer energy from or to the fluid medium.
  • a source of energy or to an output, depending upon whether or not the device of FIG. l is being used to transfer energy from or to the fluid medium.
  • this invention is operating as a pump, and therefore at least one of the shafts 10 will be connected to some sort of driving or energy source.
  • This energy source may be of any Well-known type, such as a motor.
  • FIG. l there is also shown an inlet 11 and an outlet 12. It is through this inlet 11 that a source of working uid is available or is made available to the machine of this invention.
  • the source of the fluid is not shown herein but may be any well-known source of iluid such as a tank of fluid. Further, this fluid will be exhausted to the outlet 12, with the outlet 12 of the machine of this invention connected to a Working device lto utilize the energy imparted to the iluid by this invention.
  • the machine of this invention also has an inlet passage 13 and an outlet passage 14. These passages provide, in conjunction with the housing means 15, the required guidance for the fluid flowing between the active members 16.
  • active members 16 are mounted on a moving means such as a belt 17, which, in a pump, is rotated by the force applied to the shaft or shafts 10.
  • the moving members or active members 16 are transported through the housing means 15 and through two sealed or relatively tight fitting openings 18 during ingress and egress.
  • the housing 15 and the moving active members fit snugly at the points of ingress and egress.
  • the active members 16 are arranged in a cascade fashion, the cascade being in the direction of motion of the active members 16.
  • These active members 16 have a predetermined camber.
  • the fluid enters the inlet 11 and proceeds through the inlet passage 13.
  • the iluid particles are passed between different ones of the active members 16 and then proceed in a predetermined manner such that substantially all the fluid passes at least a second time between the active members. Due to the snug tit of the inlet and outlet passages, and the housing in relation to the active members at the points of ingress and egress, the fluid is substantially all forced to follow the path shown in FIGS.
  • the machine of this invention provides for a general lluid energy increase in the direction of motion of the active members.
  • the energy level of the individualizid particles is increased in the pump means of this invention during each and every passage between the active members prior to entry into the outlet passage.
  • the housing is provided with an aerodynamically smooth surface and is absolutely devoid of any vanes or guiding means within the housing.
  • the fluid as it approaches for the first time part of the set of active members 16 at station A-A, has a uniform total energy distribution.
  • the inlet passage 13 and the portion 19 of the housing 15 are shaped in such a fashion that the velocity vector distribution at station A-A is uneven. This velocity vector distribution is required in order that the lluid particles, after their rst passage between said active members at station B-B, have a total energy distribution conforming to the general total energy distribution throughout the machine in the direction of motion of the active members.
  • the tluid has an uneven total energy distribution.
  • the outlet passage 14 and the portion 20r of the housing 15 are shaped in such a fashion that the fluid particles, after the K let passage 14 until egress from the machine through outlet 12.
  • the cascaded active members 16 may follow any path i i between the ingress and egress openings 18.
  • a machine of this invention will always have an ingress and egress opening and the active members, or the cascaded active members, will always pass these openings. If the path of the active members is rotary, then the openings 18 into the housing 15 will be connected.
  • FIGS. 1 and 2 show a linear motion of the cascade within the machine
  • FIGS. 3a and 3b show a rotary motion
  • the ,device comprises a single shaft 33 with a rotor disk or arms 34 secured to the shaft.
  • belt 17, which carries blades 16 is secured to the peripheral edge of the disk 34 or outer ends of the arms 34 and the housing 15 extends around the rotor and is obviously curved rather than elongated.
  • a shroud means such as the shroud means 31, as shown in FIG. 3a, connected to the active members 16.
  • a shroud means may vary anywhere from a simple shroud performing strictly mechanical functions well known to persons skilled in turbomachinery, to a shroud which performs not only certain mechanical functions but also performs' additional functions within the concepts of this invention.
  • the additional function which a shroud means such as that shown in FIG. 3a performs is the assistance of the walls of the housing 15 in directing the iluid with a minimum of internal losses as the iluid flows from the inlet 11 to the outlet 12.
  • the elliciency of the machine of this invention is improved with the addition of the shroud means 31, as shown in FIG. 3a, or of the separate stationary means 32, as shown in FIG. 3b.
  • This stationary means 32 also may vary in shape. As shown in FIG. 3b,
  • this inner stationary member 32 is completely disposed within the space bound by the inner surface of the housing 1,5.
  • the active members 16 are arranged in a cascade fashion. This cascade is in the direction of motion of the active members 16 as they pass through the housing 15.
  • the active members 16 may be arranged at any position on the periphery of the channel cross section as shown in FIG. 3a or 3b of the housing 15 in a plane perpendicular to the direction of motion of the active members.
  • the angle of incidence isL preferably small. Each active member thus works within its optimum operating region.
  • the limits of practical incidence variation over the operating range of the machine may be controlled. If compressible fluids are used in the machine of this invention, the passage area may diminish in the direction of the increased lluid density. Such changes in the passage area are Well known ⁇ to those skilled in the turbomachinery art.
  • the projected area ⁇ of these active members 16 in a plane perpendicular to the direction of motion of the active members 16 is less than the projected area of the remainder of the flow channel in the housing means 15.
  • the machine does not operate most elliciently if the remainder of the ilow channel area:
  • the projected area of the active members-16 in the housing is less than the projected area of the active members-16 in the plane perpendicular to the direction of their motion.
  • Active members 16 have a predetermined configuration.
  • These active members 16 are normally of an air foil type shape and have an appropriate camber line with a thickness distribution superimposed on the camber line. Active members having a lat surface will not produce an eicient machine.
