Definitions

  • the present invention relates to a centrifugal motor pump.
  • a known centrifugal motor pump usually comprises in its motor part an electric drive motor, the main parts of which are assembled by screws and provided with fixing lugs. Such a structure requires the manufacture of numerous parts and a relatively long assembly or assembly time. The cost price of this known motor pump is therefore relatively high.
  • the present invention aimed at avoiding these drawbacks makes it possible to produce an economical centrifugal motor pump which is efficient in operation and has a simple structure which is easy to manufacture and assemble.
  • a centrifugal motor pump having a centrifugal pump and an electric drive motor with a permanent magnet rotor is characterized in that it comprises a common housing formed by two elements which can be assembled by interlocking and kept tight by a radial seal and fixed together by elastic hooks or clips.
  • a centrifugal motor pump 1 according to a first embodiment of the invention illustrated in FIG. 1, includes a centrifugal pump 2 with impeller 3 and an electric drive motor 5 with permanent magnet rotor 6 and stator 7 in U shape whose poles with cylindrical surfaces surround this rotor 6, the impeller 3 being fixed on one end of the shaft of the rotor 6 by an elastic interlocking of its hollow hub provided with internal rib on the end with retaining groove of the rotor shaft 6.
  • the centrifugal motor pump 1 comprises a common housing formed by two elements 8 and 9 which can be assembled by interlocking and kept tight by a radial seal 24 and fixed together by elastic hooks or clips 11.
  • the first 8 of these component elements which has the general shape of a weapon handle surmounted by a flat guard is constituted at the location of the handle by a rotor chamber 14 at the location of the flat guard by a pump plate 15.
  • the second 9 of these elements which has the general shape of a fixed turret is formed at the location of the dome of this turret by a pump casing 17 and at a point on the side wall of this turret by a lug 18 intended fixing the motor pump 1.
  • the rotor 6 which rotates the impeller 3 of the centrifugal pump 2 is kept free to rotate by two bearings 20, 21 mounted at the two ends of the rotor chamber 14.
  • the pump plate 15 comprises on the one hand in its periphery an axial flange 23 intended to receive by interlocking the pump casing 17 and provided with a radial seal 24 which seals the assembly and on the other hand in its flat edge has notches or holes 26 intended to receive staples or elastic lugs with hooks 11 for fixing the pump housing 17.
  • the pump housing 17 includes a recess 29 serving as a pump chamber for the centrifugal pump 2, -a tubing axial 30 intended for the entry of a liquid sucked into this pump chamber, -a lateral tube 32 for the exit of the pumped liquid from this pump chamber, -elastic staples or axial lugs with hooks 11 intended for the fixing of this pump casing 17 on the pump plate 15, and a lug 18 comprising screw holes 33 for fixing the motor pump 1.
  • the two component elements 8 and 9 of the common housing of the centrifugal motor pump 1 are preferably made of a mechanically resistant, moldable or injectable material.
  • the element 8 which comprises the rotor chamber 14 is at least made of a non-magnetic material.
  • the element 8 is preferably produced simultaneously with the radial seal 24 by a bi-material molding.
  • the casing of the centrifugal motor pump 1 can thus be easily manufactured by molding, quickly assembled by interlocking and kept fixed by snap-fastening of the elastic axial clips or hook lugs 11 in the notches or holes 26 of the pump plate 15.
  • the impeller 3 is mounted by elastic interlocking on the end of the rotor shaft 6, then the pump housing 17 is fixed to the pump plate 15 by fitting the edge of this pump housing on the axial flange 23 provided with the radial seal 24 of this pump plate and by engagement of the elastic staples or lugs with hooks 11 in the notches or holes 26 until the hooks of these staples which open resiliently to pass through these notches or holes 26, close on the external face of this pump plate 15 and s grip firmly on the edge of this plate, finally the stator 7 of the drive motor 5 is mounted by engagement of the poles with cylindrical surfaces of this stator 7 on a cylindrical part of the outer wall of the rotor chamber 14 and by hard friction sliding of this stator to a preset location.
  • the seal between the pump plate 15 and the pump casing 17 is achieved not by an axial seal compressed by tightening with fixing screws as in certain known motor pumps, but by a combination of a casing 17 and plate 15 fitting pump and a radial seal 24 inserted between this casing and this plate. Contrary to the double role of the screws of certain known motor pumps, the staples or elastic lugs with hooks 11 have only the task of keeping the elements 8 and 9 assembled and do not contribute to achieving their sealing.
  • the assembly of the centrifugal motor pump 1 is thus done in the absence of any screw fixing. This operation can be easily and advantageously mechanized.
  • the centrifugal motor pump 1 is then ready for operation and to be fixed to a support by means of screws mounted in the screw holes 33 of the tab 18 of the pump housing 17.
  • the lug 18 integral with the pump housing 17 intended for fixing the motor pump 1 is replaced by a lug 35 forming an integral part of this pump housing 17.
  • the lug 35 comprises a clamping plate 36 provided with tapped holes 37 and a housing 38 intended to hold in position and immobilize in rotation this clamping plate 36 in order to facilitate the screwing of the screws or studs for fixing the motor pump 1.
  • the lug 18 secured to the pump housing 17 intended for fixing the motor pump 1 is replaced by a lug 40 provided with elastic clips or hook hooks 41 intended to be hooked to the edges of the holes or notches 42 of a support 43 when the centrifugal motor pump 1 is attached to this support.
  • the assembly and the fixing of the centrifugal motor pump 1 which is done by interlocking, by adjustment and by holding by hooking by means of staples or elastic lugs with hooks, can be easily all mechanized.
  • the cost price of the centrifugal motor pump 1 is advantageously relatively low and advantageous.
