Mud Pump Crosshead Piston‑Rod Lock Expansion Sleeve

Dezhou Yangda Petroleum Machinery Co., Ltd. manufactures high‑quality expansion sleeves, high‑precision Petroleum machinery accessories. They are essential Mud pump parts for crosshead‑piston rod connection assemblies of reciprocating compressors and oilfield mud pumps, widely applied in oil‑well drilling, chemical, hydrogen and natural‑gas high‑pressure projects.   As a hydraulic locking component, all fitting dimensions of our expansion sleeve are finished by CNC precision machining. It is installed at the joint between crosshead and piston rod inside the Mud pump power end. Radial expansion generates clamping force to achieve keyless firm connection and transmit alternating reciprocating loads. The keyless design removes stress concentration caused by key‑grooves, guarantees excellent assembly coaxiality, enables easy disassembly and reliable positioning. Though not a component of the Mud pump fluid end, it is important Oil drilling equipment parts for long‑term stable operation of…
