Dezhou Yangda Petroleum Machinery Co., Ltd. manufactures premium upper and lower guide plates, heavy‑duty
Petroleum machinery accessories. They are critical
Mud pump parts for crosshead assemblies of reciprocating compressors and oilfield mud pumps, widely used in oil‑well drilling, natural‑gas and chemical high‑pressure working conditions.
Divided into upper guide plate and lower guide plate, all sliding surfaces are finished by
CNC precision machining. The plates are mounted on the top and bottom of crossheads inside the
Mud pump power end, forming sliding tracks for reciprocating movement. They bear lateral thrust from crossheads and keep linear motion. The sliding clearance between piston and cylinder can be adjusted by adding or removing shims, which guarantees piston‑rod coaxial accuracy and prevents eccentric wear. Though not spare parts of the
Mud pump fluid end, they are vital
Oil drilling equipment parts for stable long‑term operation of power‑end assemblies.
Made of high‑wear‑resistant gray cast iron or ductile iron with aging‑stress‑relief treatment and precision machining, our guide plates feature high flatness, low friction coefficient and good impact resistance. Worn‑out guide plates can be replaced independently instead of changing the whole crosshead, which greatly cuts your maintenance expense. Every piece is inspected for flatness and wear‑resistance before shipment for perfect host‑machine fitting.
Dezhou Yangda Petroleum Machinery Co., Ltd. supplies crosshead guide plates in various sizes and accepts custom production according to your drawings. We provide one‑stop sourcing service of complete Mud pump parts for worldwide buyers. Overseas customers are welcome to send specifications or drawings for quotations.
