1. Product Overview

2. Material & Production Technology

• Uniform wall thickness design to disperse pressure evenly without local stress concentration;

• Precision inner bore matching the outer circle of cylinder liner for tight fitting and coaxial positioning;

• Outer circumference with positioning shoulders and bolt fitting surfaces to lock with cylinder flange;

• Surface shot blasting + anti-corrosion coating, resistant to mud, water vapor and outdoor harsh construction environment;

• Built-in annular sealing grooves for installing sealing rings to isolate mud infiltration between cage and liner.

3. Key Structural Features

1. Full-surround limit structure

   The cage wraps the main body of cylinder liner comprehensively, prevents liner expansion, bouncing and radial offset under high-pressure reciprocating impact, greatly reduces liner eccentric wear.

2. Load-sharing pressure-bearing design

   Transmit part of the slurry impact force to the fluid end pump housing, reduce direct pressure borne by the thin-walled cylinder liner and extend liner service life.

3. Integrated positioning step

   Dual front and rear shoulders cooperate with cylinder flange and cylinder liner flange to lock the liner in three directions (axial, radial, circumferential), eliminating liner loosening risk during continuous pump operation.

4. Standard interchangeable size

   Unified inner diameter, outer diameter and mounting hole parameters, compatible with mainstream mud pump cylinder liners and flanges, easy independent disassembly and on-site replacement.

4. Core Functions

1. Cylinder liner protection & fixation

   Wrap and restrain the cylinder liner to avoid deformation, jumping and offset caused by high-pressure drilling fluid impact.

2. Auxiliary pressure bearing

   Disperse cyclic hydraulic shock, reduce the load of the cylinder liner and fluid end pump body.

3. Auxiliary sealing isolation

   Cooperate with sealing rings to block high-pressure mud from seeping into the assembly gap between liner and cage.

4. Maintain assembly coaxiality

   Ensure the concentric operation of liner, extension rod and piston, lower wear loss of pistons and packing consumables.
