Intermediate Rod

In the field of oil drilling and geological exploration, mud pump as one of the key equipment, its performance directly affects the efficiency and safety of drilling operations. Intermediate Rod, as an important part of the power end of the mud pump, undertakes the key task of converting the rotating motion into a linear reciprocating motion to ensure the efficient operation of the pumping system.
Product overview
Intermediate Rod is a key component that connects the crankshaft and piston of the mud pump, and converts the rotary motion of the crankshaft into the linear motion of the piston through the crank connecting rod mechanism. This conversion mechanism enables the mud pump to effectively convert the mechanical energy into the power of fluid transport, so as to realize the circulation of drilling fluid. Products are designed and manufactured to strict standards to ensure stability and reliability in high-pressure, high-load working environments.
