The middle tie rod is one of the important accessories for the power end of the rig123.net' target='_blank'>drilling mud pump, and its function is to transmit the power to the hydraulic end.

The middle tie rod is made of 35CrMo. The surface is chrome-plated and the surface is smooth, which greatly improves the wear resistance and corrosion resistance.

The middle tie rod, also called the rod, is a key part of the boundary between the power end and the hydraulic end. It is an important part of connecting the crosshead and the piston rod. Its function is to transmit the power to the hydraulic end. One end is connected to the crosshead, the other end is connected by a clamp and a piston rod, and its outer circumference is filled with a packing box assembly. In the reciprocating motion, the outer circle of the intermediate tie rod and the seal member in the packing box rub against each other, and in order to ensure wear resistance, the outer surface of the intermediate tie rod is subjected to hard chrome plating treatment. The middle tie rod is made of 35CrMo, and the surface is smooth after chrome-plated finish, which greatly improves the wear resistance and corrosion resistance.
