Abstract
A multi-plunger reciprocating pump comprising a generally horizontally extending crankshaft and a plurality of generally horizontally extending cylinders alternately disposed at least generally above and below the centerline of the crankshaft. An oil pan is detachably mounted in the crankshaft housing below the crankshaft, whereby the oil pan is readily removable to facilitate axial removal of the crankshaft; and the crossheads connecting the crankshaft driven connecting rods to the piston rods are slidably mounted by bearing shoes adapted to be rotated 90.degree. for facilitating access thereto. Also, the suction and discharge valves for the cylinders are readily accessible without disconnection of any of the piping or manifolds of the pump.
Claims21
A multi-plunger reciprocating pump comprising a generally horizontally extending crankshaft, a plurality of generally horizontally extending cylinders alternatively disposed at least generally above and below the centerline of said crankshaft, conduit means operatively associated with each of said cylinders for supplying fluid to, and discharging pumped fluid from, said cylinders, valve means for controlling fluid flow through said conduit means to-and-from said cylinders, a piston movably disposed in each of said cylinders for reciprocation therein, and connecting means connecting said crankshaft to said pistons such that rotation of said crankshaft causes driven reciprocation of said pistons in said cylinders, wherein said connecting means for each said piston comprises a connecting rod connected to said crankshaft to be driven thereby, a piston rod connected to the piston, and a crosshead connecting said connecting rod to said piston rod, and further comprising arcuate way means disposed adjacent two opposite sides of each said crosshead, arcuate bearing shoe means mounted to such two opposite sides of each said crosshead slidably supporting the crosshead on its said way means, and other arcuate shoe means mounted to each said crosshead intermediate its said acruate bearing shoe means, whereby 90.degree. rotation of said crossheads causes said other shoe means to support said crosshead on said arcuate way means.
A multi-plunger reciprocating pump comprising a geneally horizontally extending crankshaft, at least three generally horizontally extending cylinders, a first of said cylinders being disposed at least generally above the centerline of said crankshaft and a second of said cylinders being disposed at least generally below the centerline of said crankshaft, conduit means operatively associated with each of said cylinders for supplying fluid to, and discharging pumped fluid from, said cylinders, valve means for controlling fluid flow through said conduit means, a piston movably disposed in each of said cylinders for reciprocation therein, and connecting means connecting said crankshaft to said pistons such that rotation of said crankshaft causes driven reciprocation of said pistons in said cylinders, wherein said connecting means for each said piston comprises a connecting rod connected to said crankshaft to be driven thereby, a piston rod connected to the piston, and a crosshead connecting said connecting rod to said piston rod, and further comprising arcuate way means disposed adjacent two opposite sides of each said crosshead, arcuate bearing shoe means mounted to such two opposite sides of each said crosshead slidably supporting the crosshead on its said way means, and other arcuate shoe means mounted to each said crosshead intermediate its said arcuate bearing shoe means, whereby 90.degree. rotation of said crossheads causes said other shoe means to support said crossheads on said arcuate way means.
A multi-plunger reciprocating pump comprising a generally horizontally extending crankshaft at least three generally horizontally extending cylinders, a first of said cylinders being disposed at least generally above the centerline of said crankshaft and a second of said cylinders being disposed at least generally below the centerline of said crankshaft, conduit means operatively associated with each of said cylinders for supplying fluid to, and discharging pumped fluid from, said cylinders, valve means for controlling fluid flow through said conduit means, a piston movably disposed in each of said cylinders for reciprocation therein, and connecting means connecting said crankshaft to said pistons such that rotation of said crankshaft causes driven reciprocation of said pistons in said cylinders, wherein said connecting means for each said piston comprises a connecting rod connected to said crankshaft to be driven thereby, a piston rod connected to the piston, and a crosshead connecting said connecting rod to said piston rod, and further comprising housing means enclosing at least a portion of said crankshaft, and oil pan means mounted within said housing means adjacent the lower side of said crankshaft, for containing lubricating oil;
- and wherein said oil pan means is detachably mounted within said housing means for selective removal thereof, from said housing means, to facilitate an axial or horizontal removal of said crankshaft from said housing means unobstructed by said oil pan means.
A multi-plunger reciprocating pump comprising a generally horizontally extending crankshaft, a plurality of generally horizontally extending cylinders alternately disposed at least generally above and below the centerline of said crankshaft, conduit means operatively associated with each of said cylinders for supplying fluid to, and discharging pumped fluid from, said cylinders, valve means for controlling fluid flow through said conduit means to-and-from said cylinders, a piston movably disposed in each of said cylinders for reciprocation therein, and connecting means connecting said crankshaft to said pistons such that rotation of said crankshaft causes driven reciprocation of said pistons in said cylinders, wherein said connecting means for each said piston comprises a connecting rod connected to said crankshaft to be driven thereby, a piston rod connected to the piston, and a crosshead connecting said connecting rod to said piston rod, and further comprising housing means enclosing at least a portion of said crankshaft, and oil pan means mounted within said housing means adjacent the lower side of said crankshaft, for containing lubricating oil;
- and wherein said oil pan means is detachably mounted within said housing means for selective removal thereof, from said housing means, to facilitate an axial or horizontal removal of said crankshaft from said housing means unobstructed by said oil pan means.
