Benefits of technology

[0006]The present disclosure also introduces an apparatus that includes a pump assembly having a crankshaft. The crankshaft includes main journals and crankpin journals. The pump assembly also includes rods each operatively coupled with a corresponding one of the crankpin journals, reciprocating members each operatively coupled w

Problems solved by technology

However, due to their size and/or weight, a limited number of pumps may be mounted on a single truck or skid.
This also increases the size, weight, and cost of the pump(s).

Abstract

A pump assembly that includes a crankshaft having main journals and crankpin journals, rods operatively coupled with the crankpin journals, reciprocating members operatively coupled with the rods, and an electric motor operable to rotate the crankshaft. The electric motor includes a stator and a rotor. The rotor is directly connected with the crankshaft and is operable to rotate the crankshaft to move the plurality of rods and reciprocating members to move a fluid.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority to and the benefit of U.S. Provisional Application No. 61 / 973,065 entitled “Integrated Electric Motor Power-end for Reciprocating Pumps,” filed Mar. 31, 2014, the entire disclosure of which is hereby incorporated herein by reference.Background of the Disclosure[0002]In oilfield operations, reciprocating pumps are utilized at wellsites for large scale, high-pressure operations. Such operations may include drilling, cementing, acidizing, water jet cutting, and hydraulic fracturing of subterranean formations. In some applications, several pumps may be connected in parallel to a single manifold, flow line, or well. Some reciprocating pumps include reciprocating members driven by a crankshaft toward and away from a fluid chamber to alternatingly draw in, pressurize, and expel fluid from the fluid chamber. Hydraulic fracturing of a subterranean formation, for example, may utilize fluid at a pressure exceeding 10...
