PUMP.
vApplication led March 6, 1926. SeraltNo. 92,766.
The invention relates toV an improvement in pumps of the submerged type and operating under iiuid pressure. rlhe principal object of the invention is to prevent wastage of power by prevent-ing the admission of the air under pressure to the pumpuntil the -water or other fluid has actherein to a certain extent, thus preventing attempted operation of the pump in the absence of suiiicient water! or other fluid therein for pumping purposes. A.- further object is the utilization of the water level within the pump proper as a means for limiting the pumping or ejectmg a particular cycle, whereby a .maximum discharge is insured'in all operations. Y
1 The invention panying drawings,
Fig. 1 is a plan pump. l y
Fig. 2 is a section of a portion of the pump taken -on the line 2--2 of Fig. 1.
Fig. '3 is a vertical section of the pump is illustrated in the accom`V in which:
view of the improved taken on the line 3-3 of Fig. 1, the parts being shown in normal positions, that is, the posit-ions assumed while water or other fluid is accumulating in the pump cylinder. Fig. 4 is a view-l similar to Fig. 3, with the parts in pumping position.
The improved pump is. made up of two main parts, a cylinder 1 and a valve section 2. rlhe cylinder 1 comprises a cylindrical body ofappropriatelength in diameter having an inlet 3- inthe bottom,controlled by a gravity valve 4, slidably mounted upon a stem 5 and limited inmovement by the head 6` of the stem. Thus when submerged, and in the absence of pressure within the cylinder, the valve 4 opens to freely admit the -surrounding liquid to the interior of the cylinder.
The valve section 2, which is in the form of a casting, has a base 7, which is removably secured in aI fluid tightmanner to the upper end of the cylinder 1 by threaded bolts 8. This casting is interiorly 'formed immediately above the base and to one side of the center thereof with an air exhaust or discharge passage 10,*vvhich communicates with the interior of the cylinder through a port 9 formedv in the base. That portion of the base surrounding the port 9 on the cylinder side of the base is formed to provide a valve seat 11, and a -valve 12 is arranged to close this port from the cylinder side,v
The valve 12 is Aprovided with a stem 13 which extends upwardly in the casting and seats loosely in a sleeve 14 depending from an enlarged head plate 15-and guided in a projection 16 rising from the upper wall 17 of the discharge passage 10, a spring 18 surrounding the guide 16 and bearing between the wall 17 and the head 15, and normally holding the plate '15 at its upper limit of movement. The plate 15 overlies the upper wall of the casting proper, which throughout the area of the plate is formed to present a concave depression 19, and the plate 2O is secured to the casting overlying and closf ingl this depression to form a pressure'chamber 21. Between the plate 2O and the correspondingv edge ofthe concave depression 19, there is arranged a flexible diaphragm 22 which overl'ies and at all ltimes bears on'the valve plate 15.
The valve section 2 beyond the plate 2O is formed for the reception or connection of the service pipes, such as a ywater discharge pipe 23, which extends through the valve section and into the cylinder 1, terminating above the lower end of the cylinder; an air discharge or exhaust pipe 24 which extends into. the valve v'casing and is in open communication with'the exhaust passage 10; and an air pressure pipe 25 suitable sourceof air under pressure to and within. the valve section below the exhaust l passage 10.
Theair pressure pipe 25 opensinto a valve chamber 26 in the base 7l of the valve section, communicating with such chamber through va. plurality of openings 27 formed in abushing 28 Vfor the chamber. A sliding valve 29 having an annular channel 30 is slidable in the'bushing, and obviously when in line with the openings 27, will cut oft communication between the air pressure pipe and the Vcylinder 1, while when the valve is raised above the openings 26, the air under pressure fromy the pipe 25 may freely enter the cylinder. The outlet from the `valve chamber 26 to the cylinder 1, is normally closed by a platel, and a pipe 32 extends through the plate to establish communication between the valve chamber and cylinder, the specific function ofvthis pipe being later described.
The-valve section 2 is formed near one edge with' a passage which extends through rleading froml any y movement of the lever 37.
of the concave depression 19 and through a registering passage 84 in the plate 20, opening through the bottom of said plate above the diaphragm V22. Pressure admitted through this passage 38 therefore will act o-n the diaphragm to depress the valve plate and thereby open the valve 12, under certain conditions to be explained.
The valves 12 and 29 are provided with extensions and 35 respectively, which connected to a lever 37 pivoted at one end at 38 to an extension 39 depending from the base 7 of the valve section 2. To the lower side of the lever 37 is secured a pan el() of appreciable depth, fully o ien at the bottoni, but otherwise closed. The pipe 32, forming an extension of the pressure inlet, leads to and opens within the pan 40. ln the lower portion of the cylinder 1 is arranged a valve operator in the form of a pan-like vessel Ll1 open at the top and otherwise closed, supported for pivotal movement at 4&2 relative to a fixture L13 projecting from-the cylinder, and counterbalaneed by a weight 1M. The balance pan 4.1 is connected by a rod to a lever 4-6 pivotal-ly supported on the lower side of the base 7 of the valve section 2 and provided at an appropriate point with a valve disc 47 adapted to control the pas-V .if 99 sage ou.
'il he chamber above the diaphragm 22 has I anormally open bleed passage 4&8V leading to the air exhaust pipe 2e, balance bleed openings 49 being formed between the chamber 21 and the exhaust passage and between the interior of the sleeve 14; and the chamber 21.
Normally, the valve 29 will be in position to cut off air pressure admission to the cylinder and the valve 12 will bc in open posi tion to establish communication between the air exhaust and the cylinder, the position of these valves being incident to the gravital Assuming the pump submerged in the water to be pumped, valve l opens and water fills the cylinder until closing the open end of the pan 10. Under the pressure on the air trapped in this pan, the further accumulation of water moves the pan upwardly, closing the valve 12 Yand opening the valve 29. Air under pressure is admitted to the surface of the water within the cylinder, acting in the usual way to force said water through the discharge pipe 23. the level of the water falls incident to this discharge, the level recedes below the pan 41, which being open at the top is left filled with water. This over-balances the weight 411, opens the valve 4:7, permits the pressure to enter above the valve diaphragm` and by reason of the greater area of the valve plate 15 ,to depress and open the valve 12. This movement of course depresses the lever 37 and cuts'ofl the admission of air pressure byV closing the valve 29. Free escape ofthe pressure is thus permitted, and on a balance being reached, water again flows into the cylinder 1, restoring the balance pan to normal position, closing the valve 47, and the cycle of operations described is repeated.
It is to be noted that the apparatus as a whole is particularly economical as tothe use of power. Under ordinary conditions, the action of the pan l0 under the incoming water would be slow, and hence there would be some wastage of power of the incoming air. livered to the interior of the pan above the level of the water therein, or at least substantially at the level of the water therein, the effect of this air is to cause an unusually' quick movement of the pan 40, the rapid closing of the valve 12v, and the consequent loss, of little, `if any, of the pressure. Of course, it is understood that the pressure being initially delivered in thersealed pan i0 will tend to insure closing of the valve 12 before suchair percolates through the water to the surface thereof around the pan.
TWhat is claimed as new, is v it pressure pump of the submergedtype,` including a cylinder having a water inlet, a water discharge pipe leading therefrom,'.an air ,pressure inlet, an 'air discharge outlet,
.valves for said inlet and outlet, a'lever 'for operating the valves, and an open pan adapted toA be sealed4 by the water in theV cylinder and designed' to A'receive the airY pressure from the inlet, said pan being connected to and operating 'said lever. I i
