Dezhou Yangda Petroleum Machinery Co., Ltd. supplies high‑quality lock springs, precision‑made
Petroleum machinery accessories. They are vital
Mud pump parts matched with packing and oil‑seal assemblies for reciprocating compressors and oilfield mud pumps, widely used in oil‑well drilling, natural‑gas transportation and chemical hydrogenation sealing conditions.
All forming dimensions of lock springs are precisely processed via
CNC precision machining. The spring is fitted around the outer circumference of sealing rings and oil‑seal rings inside the stuffing box of
Mud pump fluid end. It applies constant radial pre‑tension force to press sealing rings tightly against the piston‑rod surface, compensates seal wear automatically and keeps stable sealing pressure. It effectively prevents seal‑ring displacement and opening, greatly reducing leakage of process gas and lubricating oil. Though installed in the fluid‑end sealing system, it protects the lubrication environment of
Mud pump power end, and serves as indispensable
Oil drilling equipment parts for complete drilling equipment.
Manufactured from premium spring steel or stainless steel with strict heat‑treatment, our lock springs deliver steady spring force, excellent fatigue resistance and corrosion resistance. They hardly lose elasticity or break under long‑time reciprocating vibration of mud pumps, and guarantee reliable long‑run performance of sealing assemblies. Every finished piece is inspected on spring force and dimension before shipment for perfect fitting with stuffing boxes.
Dezhou Yangda Petroleum Machinery Co., Ltd. produces lock springs in various sizes and shapes, and accepts custom‑made orders according to your sealing‑assembly drawings. We provide one‑stop supply of complete Mud pump parts for worldwide buyers. You are welcome to send technical specifications for quotations.
