The extension rod is an important parts transporting the power from the driving end to the hydraulic end.
The intermediate rod, also called the intermediate rod, is the key part at the boundary between the power end and the hydraulic end, and is an important part of connecting the crosshead and the piston rod. Its function is to transfer the power to the hydraulic end. One end of the utility model is connected with a crosshead, the other end is connected with a piston rod through a clamp, and the outer circular surface of the utility model is equipped with a packing box assembly. In the reciprocating motion, the outer circle of the intermediate rod and the seal in the packing box rub against each other. In order to ensure the wear resistance, the outer surface of the intermediate rod is plated with hard chromium.
It is made of premium alloy steel through unique manufacturing process and advanced technology.Its mechanical property is improved after heat treatment.The surface is smooth,wear-resistant and anti-corrosive after chrome plating and accurate grinding.
The material of the middle pull rod produced by our company is 35CrMo, and the surface is smooth after chrome plating, which greatly improves the wear resistance and corrosion resistance. Our products have passed API 7K certification of American Petroleum Institute, and passed the certification of the third-party entity company of Rhine, Germany. The quality of our products has reached the international and domestic leading level, and won the praise of customers at home and abroad.
