HYDRAULIC CYLINDER HYKS

The hydraulic cylinder, as a link between hydraulic con- Page trol and the machine, is suitable for use in many areas of industry, such as pressing and joining applications, the General 3 chemical industry or tool making. Hydraulic cylinders can also be used without a problem in areas having extremely Operating instructions 4 high or low ambient temperatures. Basis of calculations for hydraulic cylinders 6 The Hydropa HYKS series of hydraulic cylinders exhibit a sturdy welded/bolted construction with honed and Technical data 8 seamless cylinder barrels and ground, precision hard...

GENERAL CHARACTERISTICS Piston diameter: Perm. max. operating pressure: Test pressure: Piston speed: Temperature range: Mounting position: Distance measurement: 32 to 200 mm 250 bar 350 bar 0.5 m/s to 4 m/s -30° C to +80° C any transducer or inductive proximity switch When the system is filled during operation, the hydraulic fluid must be filtered so that contamination with solids does not exceed the thresholds according to NAS 1638 Class 8 (Class 9 for 15^m and smaller) or ISO17/14. Finer filtration increases the lifetime of the equipment. Whatever the application, it must be ensured that the...

OPERATING INSTRUCTIONS STORAGE In order to ensure a long shelf life of the bearing surfaces and seals of hydraulic cylinders, and to protect them against corrosion, the piston rods should be retracted and the cylinders filled completely with oil. It is important to ensure that no air is trapped in the cylinder and that the connections are sealed airtight. The piston rod thread, the free rod end, and ball and socket joints should be coated lightly with anti-corrosion grease. If the cylinders are stored at fluctuating ambient temperatures, they must be protected with a pressure relief valve on...

REPLACMENT PARTS When ordering spare parts, always include the imprinted order number, which is located to the right of the base-end connection (in reference to the piston rod). PLEASE NOTE : Installation, repair and commissioning of cylinders may be carried out only by trained specialist personnel with the necessary expertise. Hydropa assumes no liability for any damage resulting from installation, repairs and commissioning, which were not carried out or commissioned by Hydropa.

Piston and ring surfaces / lifting and tractive forces EFFICIENCY FACTOR The values given in the table do not take into account the efficiency factor. Every hydraulic cylinder loses power due to the friction resistance of the sealing and guiding elements. Since the effect of these losses is different at different pressures, the following average values are anticipated as the efficiency factors:

PISTON FORCES PISTON SPEED p = pressure A = effective piston surface F = effective piston force d1 = piston diameter d2 = piston rod diameter p = efficiency factor of the cylinder Q = volumetric flow rate A = effective piston surface v = piston speed Effective piston force: F = p * A * p given: Hydraulic cylinder with d1 = 100 mm, d2 = 70 mm, p = 0.85, p = 60 bar [ 1 bar = 10 N/cm2 ] needed: Effective piston force (F) given: Hydraulic cylinder with d1 = 50 mm, d2 = 36 mm, Q = 12 l/min needed: Piston speed (v)

TECHNICAL DATA Buckling calculation The calculation of buckling SK is carried out according to Euler, whereby in simplified terms the piston rod and tube can be regarded as a slender rod. The tables show the permissible stroke in mm at buckling stress (compressive stress) according to Euler with 3.5 times the safety factor and flexibly guided load. Euler case 2 using articulated / swivel eye as an example = per. stroke length in mm = modulus of elasticity 2,1 = moment of area im mm4 for circular cross-section Euler case 3 using head flange as an example F = compressive force in N/cm2 A = measurement...
