Product Name: HP Cylinder for Yongda Waterjet / High-Pressure Intensifier Cylinder Body

Description:
This component is a high-pressure cylinder body, specifically designed for Yongda waterjet intensifier pumps. It serves as the primary pressure containment vessel within the intensifier assembly where water is compressed to ultra-high cutting pressures. The cylinder houses the reciprocating ceramic plunger and high-pressure seal assemblies, providing a precision-machined bore that ensures smooth plunger movement and leak-free operation. Constructed from high-strength stainless steel, it is rated for continuous operation at 60,000 PSI (approximately 4,137 bar) .

Applications:

• Used as the core pressure chamber in Yongda waterjet intensifier pump assemblies

• Positioned between the hydraulic cylinder and the sealing head assembly

• Houses the reciprocating plunger and high-pressure dynamic seals

• Suitable for ultra-high pressure waterjet systems operating at 60,000 PSI (approximately 4,137 bar)

• Compatible with Yongda brand waterjet cutting systems

Features:

• High-Strength Construction: Manufactured from corrosion-resistant stainless steel for durability under extreme pressure cycling

• Precision-Machined Internal Bore: CNC-machined to exact tolerances for proper fit with plunger and seal assemblies

• High Fatigue Resistance: Designed to withstand continuous pressure cycling from zero to maximum operating pressure without deformation

• Threaded Connections: Features precision-machined threads for secure attachment to cylinder heads and check valve assemblies

• Corrosion Resistance: Surface treated to withstand water exposure and water treatment additives

• Critical Pressure Vessel: Engineered as a durable component with long service life under normal operating conditions

Maintenance:

• Bore Inspection: Each time the high-pressure seal assembly is replaced, inspect the cylinder bore for scratches, pits, scoring, or residue buildup. Run a fingernail across surfaces to identify imperfections

• Bore Polishing: If minor surface imperfections are present, polish the inside diameter with 600-grit wet/dry sandpaper using a circumferential wiping motion only. Do not polish along the cylinder length as this may damage the bore surface

• Thread Inspection: Inspect cylinder threads for signs of wear, galling, or damage. If galling occurs, remove the cylinder, inspect mating surfaces, clean thoroughly, lubricate, and reinstall

• Replacement Indicators: Replace the high-pressure cylinder if the internal bore shows deep scratches, pitting, or wear beyond manufacturer-specified limits; if cracks are detected; if threads are damaged; or if pressure performance degradation is observed

• Lubrication: Apply anti-seize compound to threads and shoulder guides before installation to prevent galling and facilitate future removal

• Full Depressurization: Always fully depressurize the waterjet system and follow lockout/tagout procedures before removing or servicing the cylinder

• Handling Caution: The high-pressure cylinder is heavy. Support its weight during removal and installation to prevent damage to the plunger or injury to personnel

• Use Proper Tools: During seal removal, use specified seal removal tools to avoid scratching the cylinder bore
