PUMP AND MOTOR UNIT.
Specification of Letters Patent.
Application filed June 14, 1920. Serial No. 388,726.
erence marked thereon, which form a part of,
this application.
This invention relates to improvements in pumps and particularly to-electrically driven pumps, the principal object of the invention being to produce a pump and driving motor incorporated into a single unit in such a manner that a mlnlmum of space 15 taken up by the same, and it may be submerged under water and still perform efficiently.
In fact the pump is particularly intended to be so used, and for this reason is admirably adapted to serve as a deep well pump, since the pump and its driving means being self-contained, and the electric motor needing, of course, no connections to the surface other than a flexible cable, long lengths of shafting are done away with, and the entire unit maybe suspended from the discharge pipe. Since this pipe extends centrally and vertically of the pump," the bore of the well need be no larger than is necessary to accommodate the pump itself.
A further object of the invention is to produce a simple and inexpensive device and yet one which will be exceedingly effective for the purposes for which it is designed. TheSe objects we accomplish by means of such structure and relative arrangement of parts as will fully appear bya perusal of the following specification .and claims.
The figure on the drawings represents an elevation, half in section, of our improved pump structure.
Referring now more particularly 'to the character of references on the drawings, the numeral 1 denotes the lower casing member, provided with a central bore 2, into the lower end of which an intake pipe 3 of any necessary length is screwed.
Turnably mounted in the bore 2 is a runner 4 comprising a sleeve 5, the upper end of which flares outwardly to form a continuous horizontal discharge outlet 6, such outlet having spaced walls 7 connected at intervals by vertical vanes 8. The casing 1 adjacent the lower end of the sleeve is provided with a concentric pocket 9 having waterproof packing materlal 10 therein to prevent the passage of water between the sleeve and easing thereabove.
The discharge opening 6 empties into a circular chamber 11 formed in the upper casing member 12, which is spaced from the lower casing 1, the two being securely connected by an outer couplin sleeve 13, this connection being so accomplished that an absolutely water tight joint is had.
A removable cap 16 is seated on the eas- Patented Feb. 7, 1922.
The wall 18 is connected to the cap-wall 16 by spaced webs 21, so that there is ample room for the passage of the water from the chamber 11 to the pipe 17.
Fixed to the sleeve 5 between the casings 1 and 12 is a rotor member or armature 22, surrounding which is a field magnet 23 fixed against rotation in the space between the two casings, and having coils 24 on both ends seated in pockets 25 in said casings.
Energy for the motor is supplied by means of a cable 26 which may of course be led to the surface without any trouble.
Since we do not claim anything on the construction of this motor, we will not enter into a detailed description of the same, since it is presumed that it will be built up of such materials and in a manner best suited to economy and efficiency of operation, all parts being thoroughly waterproofed where necessary.
The rotor 22 rests on a ball or similar anti-friction bearing 27 seated in the casing tages of which 'are'well known.
The lower casing is provided with an oil pocket 28, having a duct 29 leading to the pocket'9, so that the packing may be. constantly lubricated.
If-rendered necessary or desirable under certain conditions of operation, the cap 16 may be removed, and another pump unit, but minus the motor, placed on top of the driven unit and coupled thereto, so that a staged pump will be had, the intake of the upper member receiving its supply from the discharge of the lower. one.
From the foregoing description it will be readily seen that we have produced such a device as substantially fulfills the objects of the invention as set forth herein.
While this specification sets forth in detail the present and preferred construction of, the device, still in practice such deviations from such detail may be resorted to and do not form. a departure from the spirit of the invention, as defined by the ap ended claims.
Having thus described our invention, What we claim as new and useful and desire to secure by Letters Patent is:
1. A pump and motor unit comprisinga hollow vertical sleeve, a runner on the upa hollow vertical sleeve, a runner on the upperendof the sleeve, a casing surrounding the sleeve and runner and forming a discharge chamber for the latter, a shoulder on the outside of the sleeve below the runner, a rotor surrounding and fixed on the sleeve and seating against the shoulder and a combination annular and thrust bearing mounted in the casing and about the sleeve below the rotor, said bearing supporting the rotor and sleeve.
In testimony whereof we afiix our signatures. v
