PUMP
Filed D80. 9, 1927 (g1/wanton hot |Oil Patented Dec. 24, 1929 ANDREW T. DUDLEY, OF PORT ARTHUR, TEXAS, AssIGNOR To THE TEXAS COMPANY, OF NEW YORK, N. Y., A CORPORATION or DELAWARE PUMiS Application ined December 9, 152i'. serial N. 5357.49;
The invention reltes to improvements in pumps, und more particularly to hot oil pumps of the steam reciprocating typ'e.
One object of my invention is "to provide a pump of the Stettin reciprocating type wherein auxiliary pumpingT means Which are ctuated iy the min pump tre provided for circulating u cooling medium round the pisti'on rod to' keep the pis'ton rod packing cool in find consequently in 'operating 'condition A further object is t'o provide auxiliary pumping means lvvliich are integral with the hot oil pump itself for meintaining a ,continuous circulation of a cooling medium around at leust portion of the piston rod or rods.
In the drawing, I have shown e hot oil pump ot' Well known construction compris'- ing in generl a steam cylinder 10, a valve or liquid chamber 12, having a hot oil inlet 14, and u discharge line 16. The valve chamber 12 is provided with the usual inlet valves 18 and discharge vulves 20. A piston rod 22 connects the steam cylinder and the valve f or liquid chamber and its operation is regulated by valve controlling mechanism indicated generally at 24.
An auxiliry cylinder 26 is attached to the liquid or valve chamber'12 and is so arranged as to enclose a portion of the piston rod 22. The outer end ot the cylinder 26 'formed with .a stufling box 28 in which suitable packing is disposed, being kept in position by a gtend 29 so as to prevent leakage around the piston rod. An auxiliary piston 30 is attached to the piston ro'd 22 and is' adapted to form working fit and to operate Within the cylinder 26. Y
Connected at each end in to the lower and upper sides of the ziuxili'ary cylinder 26 are pipes 32, 34, 36, und 38, each of which is provided With e check valve 40. Pipes 32 and 34 are suction lines and pipes 36 and 38 are discharge lines.
A drum or container 42 which of withstanding` the full Working the pump is provided and is filled ever kind of liquid the dling. A spiral coil 44, Water or other suitable is capable pressure of with Whatpump may be hanthrough which cold liquid may be circ lilted, is eir-iiged on the inside of the drui for the pulpose of co'oliii the liquid c'oritents of the v p H I 'The suction lines 32 nd 34 r connected ihto tl'ie low/er endof the vdruiii, While difs chrge liiies36 and 38 connect With the upper en il of the drum. Through the ction of the piston 22, together With thencheck valves 40, the cold lifiiii'cl coiitind the diiiin is drawn into the auxiliary cylinder 26 ivliiereit cir-` cultes for a sumcienttiiiie to cool the c l,- iiid'er iitl the piston r'od before it is Vexpel ed ind forced back fgh into the drum on lthe reverse stiokeof the piston. `It is obvious tlitt oii one 'stroke of piston rod 22,;fliiid is drav'ii into the auxiliry cylinder through pipe 34 and simultaneously fluid is expelled from the cylinder through pipe 381 On Vhe return stroke of the pistou, fluid is drawn from the drum into the' auriiliry cylinder through pipe 32 and expelled from the cylinder through pipe 36. c
The' hole in the end of the valve chamber through vvhich the pistn rod 22 extends is iide so as tb provide only lgood Working Ht with the pieto'n r'o'd and small quantity liquid will necssrily leak through froni the cheurih'er 12 into the auiilizry cylinder 2a when the pieten f die pufnp on -its disi charge stroke ino'ves towards the stm cylinder I0, but simultaneously liquid Willub'e driven from the outer end of me xuiry cylinder 26 und into the drun'i. AIlia"sniuclfi as the. drum is entirely filled, a corresponding volume of cooled liquid Will be forced outA of thedru and into' the inner end of the auxiliary ylinder ud the' pressure in the adjacent ends of the Cylinder wi1i-fhus1teequaiixized. on the return' stro'ke of the puhp t6 the right the saine preeessecurs -reih ndthe liquid uis'plaeed by the piston ifi tre auxiliary eylirider will be forcee through p'i'pe 38 int" the drum and' e corresponding volume' of) cooled liquid will be drawn out of the drum audirito the outer end of the auriliary cylinder through pipe 34, Because of the'circulation of the cool liquid from the drum through the'auiili'ary cyliu'ri der, that part Of the pisto'vrod. 22 which moves back and fo'rtl'i` through the' packing* pump auXiliry gland 29 will be kept cool, so that no injury will be done to the packing, and consequently a tight joint is easily maintained.
Under some conditions a small quantity of may be liberated by the oil in circulation, and in order to insure that the circulating system may not become gasbound and consequently have an insufficient quantity of liquid to circulate, a small pipe 46 is provvided and extends from the top of the drum 42 to the discharge line 16 from the pump. A valve 48 is provided to control the flow of gas through the line 46 and ordinarily is cracked only enough to permit the small amount of gas which may accumulate in the top of the drum to pass through. The provision of this iine also insures that the drum will always be entirely filled With liquid.
in the drawing a single cylinder pump only has been shown, but it is obvious that the same arrangement may be used for a duplex pump and one drum Would serve both cylinders.
Apparatus of preferred form and construction has been illustrated and described for the purpose of showing a way in which this invention may be used, but the inventive thought upon which the application is based, is broader than this illustra-tive embodiment thereof. and l therefore intend no limitations other than those imposed by the appended claims.
I claim:
l. The combination with a hot oil pump having an auxiliary cylinder adjacent the fluid end of the pump and through which the reciprocating piston rod of the pump extends, of a container for a Huid cooling medium, a plurality of pipes connecting the upper and lower portions of the container with the auxiliary cylinder, and means for circulating the cooling medium from the lower portion of the container through the auxiliary cylinder to cool the piston rod and then returning said cooling medium directly to the upper portion of said container.
