Fracturing pump assembly

Abstract

An improved fracturing pump is provided. The pump is reconfigurable on site. Internal components of the pump may be varied to meet the requirements of a specific operation. The reconfiguration gives the user the ability to increase or decrease the horsepower of the pump. A closed loop oil feed system provides constant and reliable lubrication even under heavy loads. The sealing system is enhanced to reduce leaks and thermal stresses. The pump also has an improved frame and chassis to reduce NVH and enhance reliability.

I claim: 
     
         1 . A fracturing pump assembly comprising: a frame having a plurality of bores formed therethrough; and a plurality of crossheads disposed in the plurality of bores, respectively, and adapted to reciprocate therein;
 a crankshaft for imparting motive power to a plunger, said plunger situated in the fluid handling end of the pump, whereby rotation of said crankshaft causes reciprocating movement of said plunger which causes fluid to be expelled from the fluid handling end of the pump.   
     
     
         2 . The pump assembly of  claim 1  wherein said frame is mounted on a skid assembly, said skid assembly attached to said frame at multiple mounting points to distribute vibration. 
     
     
         3 . The pump assembly of  claim 1  wherein a plurality of pistons are connected to respective rods positioned within said frame, each of said rods coupled to said crankshaft for imparting rotating motive power thereto, said frame separated internally by partitioning walls. 
     
     
         4 . The pump assembly of  claim 1  wherein said pistons and rods are separated by said partitioning walls.
