Product ID: 05144514 – Hydraulic Cylinder

Description:
This component is a hydraulic cylinder designed for waterjet cutting systems. It is a linear actuation device that converts hydraulic fluid pressure into mechanical force and motion, typically used to drive the intensifier piston or other hydraulic functions within the waterjet power unit.

Applications:

• Used as the low-pressure driving element within an intensifier pump, where hydraulic pressure drives a large piston that in turn drives a smaller high-pressure plunger.

• Installed in the hydraulic power pack or intensifier assembly to provide reciprocating motion for water compression.

• Suitable for waterjet cutting machines requiring reliable hydraulic actuation for pressure generation and system control functions.

Features:

• Constructed from high-strength ductile iron or steel to withstand repeated hydraulic pressure cycling.

• Precision-honed internal bore for smooth piston movement and long seal life.

• Designed with appropriate porting for hydraulic fluid inlet and outlet, typically standard threaded ports such as SAE or NPT.

• Includes mounting features such as flanges, clevis mounts, or threaded ends for secure attachment to the intensifier frame.

• Equipped with wear rings and sealing elements to prevent internal and external hydraulic fluid leakage.

• Engineered to operate at standard hydraulic pressures typically ranging from 1,500 to 5,000 psi (approximately 100 to 345 bar).

• Designed for continuous reciprocating duty cycles common in waterjet intensifier applications.

Maintenance:

• Fully depressurize both the hydraulic system and the high-pressure water system before servicing the hydraulic cylinder.

• Disconnect hydraulic lines carefully, capturing any spilled fluid and capping ports to prevent contamination.

• Remove the cylinder from the intensifier assembly using appropriate lifting equipment if the cylinder is heavy.

• Inspect the cylinder external surfaces for signs of hydraulic leakage, cracks, corrosion, or physical damage.

• Check all threaded ports and mounting features for wear or deformation.

• During overhaul, disassemble the cylinder and inspect the internal bore for scoring, galling, pitting, or ovality.

• Measure the bore diameter at multiple locations to verify dimensional accuracy within manufacturer specifications.

• Inspect the piston rod for scoring, bending, chrome plating damage, or corrosion.

• Replace all seals, wear rings, and wipers during a complete rebuild rather than reusing old components.

• Lubricate new seals with hydraulic oil or manufacturer-recommended assembly lubricant before installation.

• Tighten cylinder head nuts or retaining rings to the torque values specified in the equipment service manual.

• After reassembly, slowly pressurize the hydraulic system and check for external leaks, smooth piston travel, and proper function.

• Monitor hydraulic fluid cleanliness; contaminated fluid accelerates cylinder wear and seal failure.

• Replace the hydraulic cylinder if the bore or piston rod damage exceeds manufacturer-specified limits or if cracks are detected.
