Description
FULL ADMISSION P I TOT PUMP
This invention relates to a pitot pump and more particularly to a full admission pitot pump~ In the instant invention, a full admission pitot pump is described which may be used Eor compressing or pumping fluids and which may also be used Eor compressing or pumping fluid5 and which may also be used in comhination with a heat pump such as that described in applicant~s U. S. Letters Patent No. 4,304,104~
Pitot pumps first appeared in U. S~ patent history at the turn of the cen~ury. The evolution of the pitot pump can generally be found in United States Patent Nos. 3~348/024 3,795,459; 3,776/658 and 3,795,457.
Generally speaking/ pitot pumps comprise a rotating fluid case pump having a stationary streamline pick-up tube extending from the center of the rotating case to near the inner maximum diameter of the rotating case so that the internal passage o the pick-up tube is bent to impact against the flow rushing past the tube. By such an arrangement, the bent end of the internal passage develops both ~he centrifugal force pressure of the rotating fluid and the impacted velocity pressure of the fluid rushing past the tube. The pressure so developed, forces the fluid through an internal passage in the pick-up tube and out the discharge of the pump.
Pitot pumps such as that described above have been found to perform generally satisfactorily for liquids but they do experience performance limitations especially for gases because only a single pick-up tube in each stage is employed. In the instant application, a pitot pump is described which may be termed a "full admission" pitot pump since a plurality of passageways or pick-up tubes are employed.
A principal object of the invention is to provide a Eull admission pi~ot pump.
A still furthe~ object of t:he invention is to provide a full admission pitot pump which may be used to compress or pump fluid or gases.
A still further object of t:he invention is to provide a full admission pitot pump which includes a shrouded rotor of special design which encloses a specially designed diffuser or stator.
A further ob~ect of the invention is to provide a full admission pitot pump which permits high radius ratios for improved centrifugal compression.
A still further object of the invention is to provide a full admission pitot pump employing a shrouded and vaned diffuser or stator to permit the pitot principle to be employed for efficient kinetic energy conversion to pressure.
These and other objects will be apparent to those skilled in the art.
This invention consists in the construction, arrangements and combination of the various parts of the device, whereby the objects contemplated are attained as hereinafter more fully set forth~ specifically pointed out in the claims, and illustrated in the accompanying drawings, in which:
Figure 1 is a longitudinal sectional view of the pitot pump of this invention:
Figure 2 is an exploded perspective upstream view with portions thereof cut away ~o illustrate the rela~ionship of the rotor and stator; and Figure 3 i5 an exploded pexspective downstream view with portions thereof cut away which illustrates the stator housing member and stator.
Figure 1 is a longitudinal sectional view of the full admission pitot pump which is referred to generally by ~he reference numeral 10. The pitot pump of Figure 1 is a two-stage pump and it should be clearly understood that the pump may employ as little as a single stage or as many stages as desired. ReEerring ~o Figure 1, the numeral 12 refers generally to an outer housiny comprising rotor housing member 14, stator housing member 16, rotor housing member 18 and stator housing member 20. ~otor housing member 14 includes an inlet end 22 which is in communication with the liquid or gas to be pumped or compressed. As seen in Figure 1, the lower end of housing member 14 has a greater diameter than the upp~r end.
The upper end of stator housing member 16 is secured to the lower end of rotor housing member 14 by any convenient means. The lower end of stator housing member 16 has a diameter less than the upper end thereof and is secured to the upper end of rotor housing member 18 by any convenient means. Similarly, the lower end of rotor housing member 18 is secured by any convenient manner to the upper end of stator housing member 20.
The numeral 24 refers generally to a stator positioned within housing 12 and generally including stator portions 26, 28, 30 and 40. Stator portion 26 comprises a shaft which extends upwardly within the housing 12 and which is secured to any convenient support means referred by the reference numeral 42. Stator 2~ al~o includes a shaft portion 44 which extends from the lower end oE the housing 12 and which is mounted by any convenient means to support 46. To illustrate the princlple clearly, the upper end of rotor housing member 14 is shown ~o have a sheave or pulley 48 mounted thereon having a belt 50 or the like ex~:ending therearound which is driven by motor 52. ~ctuation of the motor 52 causes the housing 12 to be rotated with re!spect to the stator as will be described in more detail. Although rotor housing mernber 14 is shown to be rotated by a motor 52 in the drawings, it should be understood that other suitable means could also be provided for rotating the rotor housing member.
Rotor housing member 14 rotates with respect to stator portion 26 and has a suitable bearing means 54 posi~ioned therebetween. Rotor housing member 14 is provided with a plurality of spaced~apar~ vane members 56 which extend from the upper to lower ends thereof in the manner best seen in Figure 2 to define a plurality of spaced-apart passageways 58. As seen in Figure 2, the upper ends sf the vane members 56 are curved at 60 to aid in the efficient ~ntroduction of fluid thereinto. Each passageway i5 50 configured that a certain cross-sectional area progression ls maintained in proceeding down the passageway from the inlet and to the outlet end. A~ the inlet end of the passageway, a rapid increase in cross-sectional area occurs to diffuse the flow to a relatively low velocity Erom the inlet condition. This is done to minimize frictional losses within the passagewayO
For incompressible fluids, the passageway cross-sec~ional area remains constant to the outlet end. For compressible fluids, a gradual reduction in cross-sectional area may be necessary to adjust for increasiny fluid density. In this way, an optimum balance can be obtained between compression eneryy input and parasitilic energy losses due to passageway friction (internal flow losses~, "windage'l and bearing drag.
This, it is to be noted, is in contradistinction to conven~ional cen~rifugal impeller design where the fluid velocity increases rapidly reaching a very high value at the impeller outlet.
Stator portion 28 i5 poc;i tioned within the stator housing member 16 and is provided with a plurality of longitudinally curved vane members 62 defining a plurality of spaced-apart passageways 64 therebetween~ It is also recommended that a plurality of smaller vane members 66 be provided to more efEiciently diffuse the fluid to low velocities in passageways 64. Again, the cross-sectional area is to be varied to maintain low fluid velocities as in the impeller passageways~
Rotor housing member 18 includes a plurality of vane member 76 identical to vane members 56 and stator housing member 20 includes a plurality of vane members 62' identical to vane members 60.
In operation, the medium to be pumped or compressed is introduced into the intake end of rotor housing member 14 by any convenient means. As previously stated, outer housing 12 is rotated by the motor 52 so that the fluid supplied to the upstream ends of the passageways 58 is impinged upon the vane members 56 and centrifugally forced outwardly through the passageways 58. The fluid is discharged from the downstream ends of the passageways 58 to the inlet ends of the passageways 64 in the stationary stator portion 28 which converts the Icinetic energy of the rapidly rnoving fluid ~o pressure energy by the diffusion process. The meclium is passed through the passageways 64 in the stator portion 26 to the inlet end of the passageways in the rotor housiny member 18 which in turn discharges the medium to the inlet ends of the passageways in the stator portion 40. ~t should be noted that a seal means 5~ is provided between the lower exterior portion of stator portion 28 and the lower intexior portion of stator housing member 16. Li.kewise, a seal means 70 is provided between the lower exterior portion of stator portion 40 and the lower interior portion of stator housing member 20.
As previously described, as many stages of the pump may be employed as required since the pump can be axially "stacked" to provide very high pressure ratios. As the medium passes through the various stages of the pump~ the fluid is successively increasingly compressed ~in the case of gases) or the fluid is successively increasingly pressurized (in the case of liquids) to achieve efficient pumping. The full admission pitot pump of this inven~ion, by employing the shrouded and vaned diffuser or s~ator, permits the pitot principel to be employed Eor efficient Icine~ic energy conversion to pressure energy. It can be seen that the pitot pump of this invention employs a plurality of passageways in the stator which form a series of pitot probes or a series of passageways which function as pitot probes. The design of this invention by employing the full admission principle to provide low parasitic energy losses relative to compression energy expenditure thereby insuring that more efficient pumping or compress.ion will occur.
