Definitions

  • the present invention relates to a device for mounting a hydraulic component such as a pump body by sealingly fitting at least one suction connection and at least one outlet connection of said component, arranged substantially at an angle. straight relative to each other on corresponding inlet and outlet pipe ends, fixed in position and by additional fixing blocking the pump body on a mounting plate. It also relates to detachable supports in the general form of a square or an L with two branches, for mounting a pump body on a mounting plate.
  • the threaded part advantageously constitutes the plug of a threaded bore for purging the component body, which simultaneously saves the production of a threaded bore on the body of component and the closure plug of the bleed bore formed in the lower part of the body.
  • the second branch of the support has a hole or bore which is crossed by a purge nipple of the component body, formed at the lower part of the latter in service, and the purge nipple is provided with a threaded purge bore emerging inside the body and onto which is screwed a closure plug which constitutes said threaded part for the additional fixing of the component body.
  • annular elastomer sleeve is interposed between the outer wall of the bleed nipple and the inner wall of the hole or bore and is pressed axially by the head of the closure plug in the direction of the body, so as to block the second branch on the bleed nipple by axial compression and subsequent radial expansion of said sleeve.
  • the component body is in abutment on the first branch of the support by means of at least one projecting part or a bearing stud formed in projecting on the front surface of the body surrounding the inlet fitting.
  • the end of the projecting part or of the supporting stud is applied to the first branch by means of a layer, or plate or washer, of a vibration-absorbing material.
  • the end of the projecting part or of the support stud is preferably coated by gluing, adhesion or other fixing of a washer or support stud on the first branch of the support, in a vibration-absorbing material such as an elastomer.
  • the support is made of sheet metal and its first branch comprises two separate hooks each delimited on a separate side of the first branch by a slot or cutout separating from the sheet of said support and the two hooks are produced by folding the sheet metal part separated from said support.
  • the corner or the angle of the L of the plate is "broken" by a substantially flat face on which said two are formed separation cutouts, the curvature of the hooks leaving tangentially to this substantially flat face to come through the passage of the plate substantially perpendicular to the surface of this plate and ending in an end portion substantially parallel to the surface of the plate when the support is mounted on the latter.
  • the detachable support in the general form of an angle or L for mounting a body of a hydraulic component such as a pump body on a mounting plate, comprises on the one hand a first branch provided with at least one hook capable of engaging in a hole in said plate, said first branch being capable, after engagement of the hook in the hole, to come to bear by its distal end on an end of the inlet pipe, and, on the other hand , a second branch provided with a through hole for a fixing means on the lower part of the body of the hydraulic component.
  • the support is preferably made of sheet metal and has a face which "breaks" the angle of the square or of the L and on each of the lateral sides of which said hook is formed by cutting a separation slot and folding the part of separate sheet metal.
  • the pump body 1 of a motor-pump unit 2 must be mounted on a square plate 3 carrying or supporting respectively a nozzle 4 for inlet or supply of liquid to be pumped at the suction connection 5 of the pump 1 and a nozzle 6 for output or discharge of the pumped liquid.
  • the pump body 1 which constitutes the motor-pump unit 2 with the pump motor 1a, is presented in position so that its discharge connection 7, by extending the displacement of the pump body 1 according to the arrow F comes to engage, by virtue of its inlet chamfer 9, in a sealed manner on the O-ring 8 of the end piece 6 held in a groove of the end piece.
  • a detachable support 10 in the general form of a square or L, that is to say with two branches and which is shown in isolation in FIG. support 10 which is generally made of sheet metal, has a first substantially flat branch 11 and which is supported in service, as shown in FIG. 2, on the substantially flat face of the vertical wall 3a of the plate 3 and a second branch 12 which is arranged, in service, substantially perpendicular to the vertical wall 3a of the plate 3.
  • the end distal 13 of branch 11 is also supported, in service, on the inlet nozzle 4, this support being able to be produced by means of a recess or notch 13a in an arc of a circle, according to the embodiment of the support shown in Figure 4.
  • the support 10 laterally comprises two hooks 14 and 15 each formed on a separate side of a flat face 16 which "breaks" the angle of the square or the L
  • the hooks 14, 15 are separated from the sheet of the face 16 by a separation cutout 17.
  • Each of the hooks 14 or 15 is folded in a direction which extends, in service, perpendicular to the plate 3 and ends, at the distal end, by a hooking part 18 which is arranged, in service, substantially parallel to the rear flat surface of the wall 3a of the plate 3. It is possible to introduce each of the hooking parts 18 through a hole or cut 19 made in the plate 3, in the position shown in FIG.
  • the distal end 13 of the first branch 11 engaging on the inlet chamfer 4a of the end piece 4.
  • the distal end 13 (or 13a according to the variant of FIG. 4) is forced to engage under the rigid end piece 4 by elastically bending the first branch 11, in the direction of the pump body 1.
  • the hooks 14 and 15 are then deployed through the holes 19 to come occupy the position shown in FIG. 2 where the hooking part 18 is trapped behind the plate 3.
  • the first branch 11 of the support 10 is thus "elastically braced" between its distal end 13 bearing on the endpiece 4 and the underside 20 of the hooks 14 and 15 which is bearing on the bottom wall 19a of the hole 19 (see Figure 3 where we note that we have provided on the vertical face 3a of the plate 3 holes or cutouts 19 of circular shape). It is of course possible to provide cutouts 19 of generally rectangular or square shape corresponding to the generally rectangular shape of the hooks 14 or 15. It is possible to reduce or eliminate the face 16 which "breaks" the angle of the square. This face 16 eliminates the bending at right angles to the sheet while facilitating the formation of the hooks 14 and 15, the arc of which then leaves tangentially to the surface of the face 16.
  • the support 10 is generally made of relatively thin sheet metal so that the branches have good elasticity in cantilever bending (cantilever). To better resist corrosion, the support 10 can be made of stainless steel, which is more difficult to shape. According to another embodiment, the support 10 is for example made of molded plastic which has equivalent elasticity for greater wall thicknesses.
  • the second branch 12 of the support plate 10 has, preferably substantially at its center, a hole 21 generally of circular shape and of larger section than that of a stud 22 formed in the lower part of the pump body.
  • the stud 22 may have a square or rectangular section, in which case the hole 21 then has a corresponding shape but of larger dimensions.
  • the stud 22 has a threaded bore 23 passing through the pump body 1 to allow, when the pump is stopped, the liquid contained in the pump body to be purged.
  • the threaded bore 23 is normally sealed off by a threaded drain plug 24 which cooperates with an annular seal 25 when it is fully screwed into the threaded bore 23.
  • the second branch 12 is normally blocked in position after engagement of the stud 22 in the hole 21, by screwing in position the threaded plug 24 which retains, by its wide flange 24a, the second branch 12 trapped in the stud 22 and vice versa, which has the effect of maintaining the pump body 1 in position relative to plate 3.
  • one or more support studs or projections 26 are formed on the front surface 1b which surrounds the suction connection 5. These studs 26 come to bear, preferably by the intermediate a layer or plate or washer of elastomer damping 27, on the surface of the first branch 11, which is generally curved in the direction of the pump body, due to its bracing between the bottom wall 19a of the holes 19 and the suction nozzle 4. The stud (s) 26 then push back the first branch 11 in contact with the surface of the vertical branch 3a of the plate 3, at least partially eliminating the possible bulging of this branch 11 towards the pump body 1.
  • the second branch 12 is pushed down either by manual action or by the stud 22, to allow the passage of the purge nipple 22 during the approach of the suction connection 5 towards the end piece 4.
  • the holes 5 and 7 are in position on their corresponding end pieces, and as shown in FIG. 2, the hole 21 made in the branch 12 is placed opposite the stud purge 22 which crosses it as soon as the pressure on the branch 12 is released downwards in FIG. 2.
  • an elastomer sleeve 28, produced here in the form of a sleeve with support flange 29, is engaged in the free annular gap 30 existing between the interior wall of the hole 21 and the outer surface of the bleed nipple 22.
  • the sleeve 28, when in position, is stopped on the periphery of the hole 21 by its support flange 29 and comes to tighten by its internal bore surface 31 the external surface of the bleed nipple 22.
  • the threaded bleed plug 24 which can then be devoid of the annular seal 25, it can be seen that the elastomer sleeve 28 deforms in all free directions in order to trap the branch 12, expanding by its narrow part beyond the hole 21.
  • the sleeve 28 at the same time as its damped connection function between the stud 22 and the branch 12, also performs the sealing function of the drain plug 24, the flange 24a coming into sealing contact on the front end 32 of the sleeve 28 while the axial clamping firmly and sealingly applies the inner wall of its bore 31 on the outer surface of the stud 22.
  • the latter is connected to a support in four zones, each time by means of a layer of elastomer capable of suffocating the vibrations generated by the pump rotor rotating at high angular speed (generally of the order of 2000 to 2500 rpm).
  • the suction 5 and discharge 7 connections surround the corresponding end pieces 4 and 6 of the plate 3 with the interposition of at least one O-ring seal 8.
  • the support stud (s) 26 flatten the second branch 11 on the vertical face 3a of the plate 3, each by means of an elastomer washer 27.
  • the purge pin 22 of the pump body 1 is connected in a relatively elastic manner to the plate 3 by the second branch 12 of the support 10, but via the elastomer sleeve 28.
  • the motor-pump unit 2 In the mounting position, there is thus practically no direct metallic contact between the motor-pump unit 2 and the other elements of the pumping installation, which ensures optimum damping of vibrations which may arise during the life of the pump, for example following the appearance of excessive play in the bearings of the pump motor.
  • This favorable technical situation is combined with a limited installation cost thanks to the dual-use of the elements for purging the pump and having great mounting accessibility compared to known mounting systems with screw for locking the front face 1b of the pump body 1 on the vertical wall 3a of the plate 3.
  • the support stud or studs 26 can be replaced by a widening of the suction connection 5.
  • the plate 3 can carry the nozzles 4 and 6 liquid inlet and outlet, as shown in Figures 1 and 2, or the plate can simply be crossed by these tips which are also fixed on a mounting device such as a boiler on which is also fixed the plate 3. It should also be understood that the plate 3 may only have its substantially planar vertical wall 3a which then cooperates alone with the support 10.
