Abstract

The invention relates to the field of engineering equipment and particularly relates to a reciprocating pump rod device. The reciprocating pump rod device comprises a first connection device and a second rod, wherein the first connection device is connected with the second rod. The reciprocating pump rod device is convenient to assemble and disassembly; the assembly cost and the maintenance cost are greatly reduced; and the purposes of reducing the cost and improving the efficiency are achieved.

Description

technical field [0001] The invention relates to the field of engineering equipment, in particular to a reciprocating pump rod device. Background technique [0002] In the oil and gas field, a reciprocating pump live rod assembly is the assembly in a reciprocating pump that connects the crosshead to the cylinder liner in order to draw fluid into the cylinder liner or to deliver fluid out of the cylinder liner. [0003] Usually, the movable rod device of the reciprocating pump includes a pull rod and a piston rod, which is very inconvenient when installing and dismounting the piston rod. Contents of the invention [0004] In view of this, it is necessary to provide a fast and convenient reciprocating pump rod device. [0005] A reciprocating pump rod system comprising [0006] pull rod; [0007] first shot; [0008] second shot; [0009] The pull rod is connected to the first rod; [0010] the first rod is connected to the second rod; [0011] first locking device; ...
