Product ID: 20469016-2 – High-Pressure Cylinder / Intensifier Cylinder

Description:
This component is a high-pressure cylinder, specifically an intensifier cylinder or cylinder liner, designed for waterjet cutting systems. It is a precision-machined cylindrical pressure vessel within which the high-pressure plunger reciprocates to compress water to ultra-high pressures. The “-2” suffix may indicate a specific size, material variant, or design revision.

Applications:

• Used as the primary high-pressure containment vessel within an intensifier pump for waterjet cutting machines.

• Installed between the hydraulic cylinder and the check valve manifold to contain water during compression.

• Suitable for both pure water and abrasive waterjet systems requiring reliable, fatigue-resistant pressure containment.

Features:

• Constructed from high-strength, corrosion-resistant material such as precipitation-hardened stainless steel, high-alloy steel, or tungsten carbide-lined steel.

• Precision-honed internal bore with exceptional surface finish to minimize friction and wear on reciprocating plungers and seals.

• Designed to withstand cyclic pressure loading from zero to maximum operating pressure at high cycle rates, typically 60,000 psi (approximately 4,137 bar) or higher.

• Engineered with appropriate wall thickness and material properties to meet safety factors for ultra-high pressure service.

• Includes threaded ends, flange mounts, or groove features for attachment to cylinder heads, check valve bodies, or end caps.

• Resists stress corrosion cracking and fatigue failure when properly maintained and operated within rated parameters.

Maintenance:

• Fully depressurize the waterjet system and disconnect power before removing or servicing the cylinder.

• During disassembly, carefully remove the cylinder body from the intensifier frame using proper lifting techniques if the cylinder is heavy.

• Inspect the internal bore surface for scoring, galling, pitting, corrosion, or wear caused by plunger or seal contact.

• Check all threaded connections, sealing surfaces, and mounting features for damage, deformation, or erosion.

• Measure the internal bore diameter at multiple locations (top, middle, bottom) and at different orientations to verify dimensional accuracy and detect ovality or taper.

• Compare measurements to manufacturer specifications; replace the cylinder if bore wear exceeds allowable limits.

• Inspect the cylinder externally for cracks, dents, corrosion pitting, or signs of previous impact or overtightening.

• Perform a dye penetrant or other non-destructive crack detection test if permitted by the equipment service manual.

• Clean the cylinder bore and exterior surfaces thoroughly using a soft cloth and low-pressure water or compatible solvent.

• Do not use abrasive tools or harsh chemicals that could damage the bore surface finish.

• Replace the cylinder if any cracks, excessive bore wear, ovality, or thread damage is found.

• When reinstalling, lubricate seals, threads, and mating surfaces as specified in the equipment service manual.

• Tighten end caps, retainers, or mounting hardware to the torque values provided by the equipment manufacturer.

• After reassembly, slowly pressurize the system while observing for leakage or abnormal sounds; do not exceed rated pressure.

• Periodically inspect the cylinder during seal replacement intervals to identify wear before failure occurs.
