Embodiment Construction

[0038] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0039] In the present invention, the terms "first", "second", and "third" are mainly used to distinguish different components, but do not specifically limit the components.

[0040] figure 1 Shown is a schematic structural diagram of a plunger type fracturing pump according to an embodiment of the present invention. This embodiment includes a pump head body 3 and a plunger body. The structure of the pump head body 3 can refer to the existing and improved technologies, and the plunger body can reciprocate under the drive of the oil cylinder, etc., so as to realize the high-pressure delivery of the fracturing medium.

[0041] The plunger body at least includes a first plunger 1, a second plunger...

Abstract

The invention discloses a plunger type fracturing pump and an oil fracturing vehicle. The fracturing pump includes a pump head body and a reciprocating plunger body, the plunger body includes: a first plunger, the end of the first plunger is arranged in the pump head body, the The first plunger includes a first inner hole in the axial direction; a second plunger, the second plunger is arranged in the first inner hole of the first plunger; a mounting part, the installation part is arranged in the Between the first plunger and the second plunger, it is used to fasten or disengage the first plunger and the second plunger. The present invention can provide delivery of different pressures and displacements without replacing the plunger and the pump head body, has high pumping efficiency, simple structure, convenient assembly and disassembly, and low cost.

Description

technical field [0001] The invention mainly relates to the technical field of petroleum equipment, in particular to a plunger type fracturing pump and a petroleum fracturing vehicle provided with the plunger type fracturing pump. Background technique [0002] In the prior art, the plunger type pressure pump of petroleum equipment realizes the high-pressure delivery of fracturing medium through the reciprocating movement of the plunger in the pump head body (or plunger cylinder). In order to ensure pumping efficiency during reciprocating motion, the gap between the outer circle of the plunger and the pump head body (or plunger cylinder) is generally required to be less than 10mm. [0003] At present, a type of fracturing vehicle is generally equipped with at least three types of plungers, and plungers with different diameters can achieve different pressure and displacement delivery. When selecting different plungers according to the needs of fracturing conditions, it is nece...
