Abstract

The invention relates to the technical field of plunger pumps, in particular to a connecting structure and a plunger pump. The connecting structure and the plunger pump are used for solving the problems that a plunger and a pull rod are likely to wear and loosen in the prior art. The connecting structure is used for connecting a first component and a second component. The connecting structure comprises at least two oppositely-arranged clamping pieces, a first connecting assembly, a second connecting assembly and a locking piece. An installation space is defined by the at least two oppositely-arranged clamping pieces. One part of the first connecting assembly is located in the installation space, and the other part of the first connecting assembly is located outside the installation space and connected with the first component. One part of the second connecting assembly is located in the installation space, and the other part of the second connecting assembly is located outside the installation space and connected with the second component. The parts, located in the installation space, of the first connecting assembly and the second connecting assembly abut against each other. The locking piece is connected with the clamping pieces and used for fixing the clamping pieces to the first connecting assembly and the second connecting assembly. The connecting structure is applied to the plunger pump.

Description

technical field [0001] The present application relates to the technical field of plunger pumps, in particular to a connection structure and a plunger pump. Background technique [0002] Piston pump is an important oil and gas field fracturing equipment, used to transport high-pressure fluid medium. At present, the clamp connection structure of the plunger pump is a key component connecting the pull rod at the power end of the plunger pump and the plunger at the liquid end, and plays an important role in ensuring the reliability of the plunger pump. [0003] In the process of realizing the above connection, there are at least the following problems: the existing clamp connection structure is directly installed on the plunger pump pull rod and plunger, which easily causes wear of the plunger and pull rod, resulting in loosening. Contents of the invention [0004] Embodiments of the present application provide a connection structure and a plunger pump, which are used to solv...
