Product Introduction: Liner Lock Liner lock is a special locking fastener for fixing cylinder liners inside the fluid end of triplex mud pumps, widely used in oil drilling, geological prospecting and horizontal directional trenchless construction. It firmly restrains the mud liner to prevent axial displacement, loosening and impact vibration during high-frequency reciprocating operation of pistons. Forged from high-tensile alloy steel and subjected to quenching and tempering strengthening treatment, this liner lock has outstanding compression resistance, impact resistance and anti-fatigue performance. Its inner clamping surface is precisely machined to fit the outer end of the liner closely, distributing clamping force evenly without damaging the liner body. Optimized limit structure can withstand continuous hydraulic shock generated by mud suction and discharge, effectively avoiding liner shifting, eccentric wear of rubber pistons and abnormal pressure fluctuation of the pump. Standard thread and mounting dimensions realize good interchangeability with most mainstream mud pump fluid end assemblies. The whole surface adopts anti-rust and anti-corrosion coating, resisting erosion from sand-containing drilling mud and various chemical additives in harsh open-air working environments. Hexagonal operation structure allows quick disassembly with common tools, greatly shortening maintenance time when replacing worn liners on site. By locking the liner in a fixed concentric position, it reduces scrapping frequency of liners and pistons, stabilizes the output flow and pressure of the slurry circulation system, and eliminates safety risks such as liner ejection under high pressure. It is an indispensable dedicated locking component to guarantee safe and long-term stable operation of mud pump fluid end.
