Description

"IMPROVE¬ MENTS IN AUXILIAR SUCTION DISPOSITIVE, ARRANGEMENT IN IN HYDRAULICS PUMP AND IN INLET VALVE"
The present pa ent has as - object, an auxiliar suction dispositive, arrangement in hydraulics pump equipament field and which were develo ped, improved and combined to make the liquid pressure pump more efficient, preferably water.
There are certain hydrauli- — cs pumps for pressure or other liquid of a reservatory, that in spite of their efficient work present the incon venience of having the water reservoirs localized on the superior region of the carcase, with what said wa¬ ter reservoirs are localized on certain highness in re- - lation to the bottom of the reservatory and because of this, the water that is under said water reservoirs is not taken.
A pump like this is substan tially formed by a carcase, that lodges an axial and - oscillating element, whose inferior extremity is suppo¬ sed to a solenoid, the intermediate region of said ele¬ ment has a membrane central region, perphery is seated, on the carcase wall and with that, a pressure camera, with superior exits in inverted "Y" forming the superi- - or opposite extremity of said element has a cupping glass seated which opens and closes a communication pas sage between said pressure camera and an inlet camera, that communicates to means, from which the water is pum ped through an inlet valve constituted by water reser- - voirs .
In order to overcome this problem the suction auxiliar dispositive is substan¬ tially formed by a bell-shaped glass with bigger suffi¬ cient height than the pump body and it is exposed insi- - de it, said bell-shaped glass is formed superior face with a central hole through the pressure of the pump; lateral wall that in connection with the pump external surface, defines a suction auxiliar annular camera and in the inferior extremety referred bell shaped glass ex- - pects a mouth which defines the entrance of the annular suction camera and from which a water column around the pump is formed, and until on the water reservoirs; said mouth is sufficiently under the inferior extremety of the pump, a little bit over the bottom of the reservato- - ry and supported by brackets, in which the passages are defined.
The evolution of the studies related to the use of the set formed by the hydraulics pump and auxiliar suction dispositive as described above - led to more practical arrangement and efficiently com¬ prehended, basically by using the pump in a position height in relation to the bottom of the reservatory and assemble the pump in this position, inside the auxiliar external pressure camera in relation to the pump, with a - communicating opening with the reservatory and in which the water reservoirs of the pump are exposed, grant the pressure exit of the pump and for providing referred pump with new pressure exits that are in connection with the interior of the external auxiliar pressure camera - and still provide it with a pressure exit which couples with the pressure tubulation.
This way, in case of the above described pump particularly, when used according to the present arrangement it is exposed in an inverted - position, that is, with its superior surface having wa¬ ter reservoirs turned down and with no inverted "Y" pre¬ ssure exit, as well as being assembled at the bottom of the pump and still provides the mentioned pressure came¬ ra of the pump with radial openings being in communica- - tion with the interior of external auxiliar pressure ca¬ mera and said camera has its pressure exit situated or. the superior extremety.
With this arrangements given to the hydraulics pumps with high water reservoirs, par¬ ticularly the pump as above described, all the water vo- _ lume of reservatory can be gotten and pressurized avoid¬ ing the mentioned above inconvenient.
In a preferable construction, on the inlet valve of the pressure pump, above described is formed by a headquarter which links the inlet camera - with the means of which the liquid is pressurized this headquarter is assembled on the inlet camera wall, obta¬ ined from resistant abrasion material and that expects a central hole surrounded by other peripherical holes ex¬ posed on circunferential linen and regularly spaced that - receptor of a central fixing pin in a flexible membrane, whose perphery is exposed on peripherical roles and acts on these as valves the type of reed that is, opening and closing referred holes due to, respectively, the depres¬ sing and pressing of the interior of the inlet camera, - realized by the mentioned cupping glass during the peri¬ od when the pump is working.
Due to the good way of work¬ ing of the inlet valve according to the construction above mentioned, no problem can be attributed to it and - nothing impedes its best way of working and the pump which it belongs to.
Therefore , when the pressure exit is presented under counter pressure from the liquid column (water) and the recipient, from which the water - pressurized gets empty and has its level under the water reservoirs, the air entrance in the inlet camera is fa¬ vorable, which demages the posterior workings of the air impedes the movement of the cupping glass, that opens and closed the passage between the inlet cameras and the - pressure, to create depression inside the inlet camera in a sufficient level to open the inlet valve, that is, to bend the membrane of the valve in order to open the holes of the water entrance that interrupts this way, the pumping realized by the pump.
In order to overcome this - problem, the improvements in inlet sets, object of the present patent, as developed, which consists on providing the mem¬ brane of the inlet valve and/or the inlet camera wall, with one or more purgers holes of valved air with conformation and dis¬ position in the membrane or proper walls to be closed or open - through the compression or decompression of the inlet camera of the separation of the liquid means dealt with by the pump and by the flexibility of the material of the am brane or the flexible slug containing the valved hole and that is assembled on the hole of the wall of the camera. - Such form of constructing the inlet set solves the problem that can be seen usually on con¬ ventional inlet set and consequently on the pumps that use the same set, once it is lodged inside the inlet camera and the pump starts working, the mentioned cupping glass that - commands the communication between the inlet cameras and the pressure, on its first movements forces the air contained in the inlet camera to circulate to the outside through the valved purgers holes, from which the whole inlet set and pump start working normally. - The attached drawings show the improvements in suction auxiliar dispositive in hydraulics pump and in inlet set, the objects of the present patent, in which, fig. 1, shows a pump of the - type for which the suction auxiliar dispositive be applicable which can be used according to the arrangement on the present patent and in which the improved inlet set takes part on the conventional construction and with a partial cut; fig. 2, shows the suction - auxiliar dispositive in exploded perspective; fig. 3, shows the dispositive assembled, with pump and with cut; fig. 4, shows an amplified detail of the cut on the previous figure; fig. 5, shows a hydraulics pu p — constructed to the arrangements, obeject of the present patent; fig. 6, shows an amplified detail of the previous figure. fig. 7, shows an amplified detail and with a cut of the inlet set improved, in the position that - the inlet valve closes the water entrance to the inlet camera and opens the exit for the air eventually contained inside the inlet camera; fig. 8, shows the above detail but in a position that the inlet valve opens a passage to the - water entrance on the inlet camera; fig. 9, shows the same view as fig. 7, but in the position that the inlet valve closes the water entrance and air exit, which does not exist inside the inlet ca¬ mera; - fig. 10, shows another possibili¬ ty of constructing the improvements on the inlet set, in the po¬ sition that closes the water and closes the air exit eventually lodged on the intermediary region of the inlet camera; fig. 11, snows the set in a posi- - tion that the inlet valve opens to the water entrance; fig. 12, shows the view of fig.10 but in a position that the valve closes the ater entrance and the air exit, which does not exist inside the inlet camera;

(28) bulges superior and axially a beak (31) with echeloned external surface and in which the pressure tubulation 32 is - coupled reducing or amplifying it, that is held with the brackets (33) also being able to, without dem aging the working of the sucker element, get tied to the pressure tubulation dire¬ ctly to the exit, as it is done in the commom pumps, of the sa¬ me type. _ _ The union ring (24) is formeα by a flexible material annular body and square section (34; whose from the middle piece of internal face bulge a surround¬ ing orthogonal edge (35) and from the corners of said internal face bulge shorter edges and gauged (36) which have prismatic and thicker initial pieces (37), which in collaboration with the - central edge (35) define the gutters (38) said central edge (35) is in between the flanges (23) of the parts of the superior bell shaped glass (20) and inferior one (21) and adjustable around the body of the pump (1) in order to grant a perfect estabiliza- tion to this; the gutters (38) receive respective prismatic ferules - (32) expected on the free extremety of flanges (23) and the final gauged pieces of said edges (36) get stopped on the surface of respective flanges (23) of the parts of the bell shaped glass(20) and (21).
The inferior ring (25) of the in- - ferior part of the bell shaped glass (21) has fixing in respecti¬ ve holes (41) expected around the mouth (18) of the bell shaped glass; the external edges of said ring, has its edges(42) turned upside that are adjustable to the external face of the bell sha¬ ped glass and the mouth (18) the inferior face mentioned are - assembled on the brackets (19).
The inferior parts of the superi¬ or (20) and inferior (21) bell shaped glass are preferable cone- shaped provided with plastical material.
Thus, when the set formed by - the pump (1) and suction auxiliar dispositive is sunk in the water, the suction camera (17) between the shaped glass(13) and the body of the pump (1) is filled in. In case the water level is higher than the water reservoirs (11) of the pump, this works norm ally. - However when the level of the ater under the level of the water reservoirs (11] of the pump is on the vacuum formed over the water lamina inside the sucti¬ on camera (17) enables the making of a water column "A" betwe¬ en said water lamina (11) which guarantees the pump's normal -working, until the whole reservatory is drained.
Even if said water column is undone when the pump is turned off, said pump will work nor¬ mally again when it is turned on, once the vacuum formed over the water lamina and inside the suction camera (17) it will ma¬ ke the ater come till the water reservoirs (11) of the pump, - until there is no more liquid to be drained from the reservatory
As already seen, on the pump's normal position, the water reservoirs are exposed in an "H" hei¬ ght from the bottom (12) of the water reservatory or other liqui¬ ds, this way, normally is not able to get the whole water or - liquid that is kept in the reservatory, that is, the water or li¬ quid that are under the "H" position.
Thus the arrangement in hydrau¬ lics pump, object of the present invention consists on genericaly expose the pump in a position that its water reservoirs (11) be - at a minimum "H" height possible in relation to the botton of the reservatory, said pump exposed this way, inside an external auxiliar pressure camera (100) provided with opening (101) open to the interior of an external auxiliar pressure camera (100) provided with opening (101) open to the interior of the re- - servatory and in which the above mentioned water reservoirs ( 11 ) of the pump with new pressure exits (102) are assembled conne¬ cted to the interior of referred external auxiliar pressure ca¬ mera (100) provided with opening (101) open to the interior of reservatory and in which the referred water reservoirs (11) of - the pump with new pressure exits (102) are assembled connected to the interior of referred external auxiliar pressure camera
(100) and finally grant this last pressure exit (103) which is coupled with pressure tubulation.
Thus when said arrangement is - applicable in a pump with the characteristics of the illustrated figure one and above described, said pump is used in position (fig. 5), that is, with its .surface normally superior (104), which has the water reservoirs (11), turned down side and wi¬ thout the inverted "Y"(6) pressure exit, as well as assembled _ on the bottom is provided with a central opening (101) which lodges the water reservoir (11) of the pump, open in the outsi- de direction of the external auxiliar pressure camera (100) and still, the present arrangement consists on providing the pressure camera (5) of the pressure radial exits of the pump (102) conne¬ cting with the interior of the external auxiliar pressure camera - (100) and last, the pressure exit (103) of this, is placed on the extremety of said external auxiliar pressure camera (100) turned upside and receiving the pressure tubulation.
In a preferable construction of the external auxiliar pressure camera (100) it is formed by two - pieces of cone shaped camera, one superior(106) and the other inferior (107), that one has the superior face provided with a pressure exit (103) exposed centrally, between the piece of the inferior camera (102) having one inferior ring assembled (108) which serves as a supporting base of the set, which has cen- - trally, the inlet opening (101) lodging the reservoirs (11) and has perpherical brackets (109) that keep it exposed a little over the bottom (12) of the reservatory and still the largest adjacent extremeties of the superior carcase (106) and inferior (107) are provided with surrounding external flange (110) united by a - union ring and intermediary hindrance.
The intermediary union ring(lll. (fig. 6) is formed by a hindrance ring of a flexible material
(112), that is intercoupled between the flanges (110) of the parts of the carcase (106) and (107); a sectional "C" union ring - and resistant to deformation material (113) that coupled exter¬ nally to the flanges (117) and a sectional "C" external hindran¬ ce ring and flexible material (114), that is externally coupled with the union ring (113) and against the carcase surface, and the hindrance ring (112) intercoupled with the flanges (110) has - its edges turned to the interior of the camera provided with a crossed edge (115) and together with the external hindrance ring (114) is obtained, preferably, from rubber or similar, while the union ring (113) can be formed, e.g. by metal or other non de¬ form able or hardly deform able material. - " In another possibility of conr*.- tructing the external auxiliar pressure camera, not illustrated this can be formed by the inferior cone shaped (107) part and replacing the superior part (106) is expected a cover, which has the central opening to the pump extremety turned upside, be able to cross, naturally provided with convenient hindrance and - the pressure exit.
The inlet valve 10 (figures 8, 9 10, 11, and 12) above mentioned is usually constituted by a ri¬ gid seat (200) that assembled on the wall that defines the inlet camera 9 provided with central hole (201) surrounded by a cir- - cunferantial linen of perpherical holes (202) of passage of wa¬ ter and regularly spaced; said hole (201) receives and fixes a central seating pin (203) of a flexible membrane of command(204) that is exposed on the face of the seat (200) turned to the inte¬ rior of the inlet camera 9 and whose perphery is on mentioned - perpherical holes 202 of the ater passage, and in the external face of the seat (200) are expected saliences (205) of the assem¬ bling of the inlet valve in the pump.
The present improvement consists on providing the inlet camera 9 with valved hole of purging air -206 and for 206' constructed and exposed in a w ay as to close or open automatically through the pression and depression of the cupping glass 7, as well as by the liquid maneuvered by the pump and by the flexibility of the material in which said sal¬ ved hole of purging air 206 and/or 206'. - In a first construction of valved hole of purging air 206, designed to purge the air eventually contained in superior region of the camera 9, as figures 7 to 9 said valved hole of purging air 206 is axially exposed on the command membrane 204, extended from the external face of -the top 207 of the seating pin 203 since corresponding opposite region 208 of the internal face of the membrane; said internal opposite region 208 is surrpunded by an annular articulation groove 209 and in such region 208' a valve 210 is incorporated, formed by a conical point constituted in referred internal region -208, whose summit opens the internal extremety 212 of the valved hole of purging air 206 and insuch summit a diametral cut of"V" section 213 is expected which passes through mentioned internal extremety 212 of the hole of purging air 206, constituting this way, lips which close and open the extremety of the internal hole 212, through the compression and deco pression of the in- - terior of the inlet camera 9 made by the moviments of the cup¬ ping glass 7, as well as by the liquid maneuvered by the pump and by the flexibility of the command membrane 204' act¬ ing together.
Thus when the inlet camera 9 - has a position of air in the superior region of its interior and the pump is turned on (fig. 7) the first movements of the cup¬ ping glass 7 in a sense as to compress the camera, take the air out through the valved hole of purging air 206 of said in¬ let camera 9 and so the liquid is pressurized by the pump, this - way the set works normally (fig. 8 and 9).
Such way of working is due to the fact that there is air inside the inlet camera 9 and the cupping glass 7 moves as to compress the camera, as it can be observed in figure 7, the air impedes the pression and the li- — quid to close the valve lips 210 and referred air simutaneously forced by the pression circles through the purging valved hole 1( dotted lines in fig. 7) out of the inlet camera 9 making it in conditions to work normally.
On the other hand when there is - no air inside the inlet camera 9 and the cupping camera as fig. 9 shows, the pression and the liquid push the valve lips 210 in a position in which the purging valved hole 206 close, avoiding this way, the inadequate leaking manuevered by the pump, which if occured, it would demage the working of said - pump.
In another possibility of cons¬ tructing the valved hole of purging air 206' designed to purge the air eventually kept in the intermediary region of the inlet camera 9, that lodge due to the compression and decompression — system which the interior of " the camera is supposed (figs.10 to 12); said valved hole of purging air 206 is radial and inter- mediary exposed in the inlet camera 9, can be in a number of one or more and each one is formed substantially by a hole 214 radially in the intermediary region of the wall 215 of the inlet camera 9, which receives corresponding slug of flexible material 21b, preferably ru- - bber or similars, which has the purging valved hole 206' axially ex¬ posed and extended from an extremetry 217 of said slug, that is ex¬ ternally exposed to the inlet camera 8 and sunk in the middle of the liquid that is pumped by the pump, until the enlarged opposite ex¬ tremity 218 of said slug, that is turned to the interior of the in- - let camera 9, this enlarged extremety is not crossed by extremety 212' of said purging hole 206' and that expects a valve 210' essen¬ tially formed by conical point 211' turned down side which has a sectional "V" transversal cut 213 that passes by the extremety 212' of said valved purging hole 206' and from lips which close and open - the extremety of the internal hole 212' through the compression and decompression of the inlet camera 9, made by the movements of the liquid that is maneuvered by the pump and by the flexibility of the slug 216, acting together.
The purging valved hole 206 radi- - ally exposed in the inlet camera 9 works exactly as the valved hole of purging air 206 expected in the membrane 204, as described above but it acts more effective to purge the air lodged in the intermedi¬ ary region of the camera and confined in the middle of the liquid kept in it.
