Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

Examples

A fracturing pump box body for oil exploitation is shown in figures 1-4 and comprises a first outer wallboard 1, a second outer wallboard 2, a first inner wallboard 3, a second inner wallboard 4, a nose plate 5, a crosshead guide plate seat 6, an input shaft bearing seat 7 and a crankshaft bearing seat 8, wherein the first outer wallboard 1 and the second outer wallboard 2 are connected to form an integral outer wallboard, the first inner wallboard 3 and the second inner wallboard 4 are connected to form the integral inner wallboard, the outer wallboards are positioned on the left side and the right side of the box body, the inner wallboards are positioned between the two outer wallboards, the outer wallboards and the inner wallboards are arranged in parallel, and each outer wallboard and each inner wallboard are provided with the input shaft bearing seat 7 and the crankshaft bearing seat 8; in the middle of two second external wall boards 2, all be equipped with the cross head deflector seat 6 that tube-shape and level were placed between per two wallboard, nose board 5 is connected to the front end of cross head deflector seat 6, wallboard 4, nose board 5 and cross head deflector seat 6 integrated forming structure in wallboard 1 and the first in, second external wall board 2, the second, the junction of first external wall board 1 and second external wall board 2 is equipped with strengthening rib 9.
