Product Introduction: Positioning Disc Positioning disc is a precision limiting component matched for triplex mud pump fluid end and power end assemblies, widely used in oil drilling, geological exploration and trenchless horizontal directional drilling projects. It provides accurate positioning for valve assemblies, springs, pistons and other moving parts to avoid offset and abnormal wear during high-frequency reciprocating operation. Manufactured from high-strength alloy steel with integrated forging and multiple heat treatment processes, this positioning disc boasts high hardness, outstanding compression resistance and excellent anti-abrasion performance. The flat and smooth surface ensures uniform stress distribution under long-term cyclic impact of mud and springs, without deformation or bending. Strict CNC machining controls precise aperture and outer diameter tolerances, realizing perfect matching with supporting spare parts. Its special limiting structure effectively fixes the installation position of internal components, maintaining stable concentricity and greatly reducing eccentric friction between matching parts. With anti-rust and anti-corrosion surface coating, it can resist erosion from sand-containing drilling mud and various chemical additives, adapting to harsh outdoor working conditions. Standard specifications have strong interchangeability and support fast on-site disassembly and replacement during routine maintenance. It stabilizes the running state of mud pump wearing parts, reduces equipment vibration and pressure fluctuation, lowers failure rates and maintenance costs. As an indispensable auxiliary positioning part, it guarantees long-term stable and efficient operation of the whole mud circulation system.
