Heavy Duty Hydraulic Cylinder 3000psi
Douce Hydro's heavy-duty hydraulic cylinders are designed for a nominal pressure of 3000 PSI, adhering to NFPA and ANSI/B93.15 – 1981 standards. These cylinders are suitable for various industrial applications, including construction, with or without cushioning.
- Pressure: 3000 PSI nominal pressure.
- Cushioning: Features a floating cushioning ring with automatic refeeding, adjustable on both sides.
- Fluid: Standard fluid is mineral oil.
- Working Temperatures: Operates between -10°F to +165°F.
- Velocity: Maximum velocity is 19 inches per second.
- Design: Piston rod made of medium carbon steel, ground and polished after coating; cylinder body is steel honed.
- Protection: Primer external coating on the body cylinder; hard-chromed piston rod. KERADOUCETM coating recommended for harsh conditions.
- Brace Ring: Necessary for long strokes, adding to the overall cylinder dimension.
- Swivels Type: Standard swivels are GE…DO from INA Elges or GE…ES from SKF, with other types available on demand.
- Packing: Cylinders are delivered with all ports plugged and threaded pieces protected by peelable varnish.
- Operating: Hydraulic circuits must be tight and bled to prevent seal destruction. A bleed device is equipped at both ends of the cylinder.
- Installation: Avoid impacts, vibrations, transverse loads, and bending efforts during mechanical installation and hydraulic follow-up.
- Stocking: Store cylinders in heated shelters under normal temperature and humidity conditions. For prolonged storage, cylinders can be supplied with oil upon request.
- Marking: All hydraulic cylinders will have an identification label for spare parts.
- Tightness - Code PP: Compound-seal and guiding through bearers for piston and rod tightness, suitable for low friction and speed applications.
- Tightness - Code DC: Utilizes lipseals and V packing for hard working conditions, recommended for industries like rolling mills and steel.
