HYDRAULIC INTENSIFIERS pneumatic – hydraulic, single-acting/double-acting Description: This hydraulic intensifier transmits the energy from a pneumatic system connected ahead onto the hydraulic system. Once compressed air is supplied a piston with high-pressure pipe is pushed against a plunger. After a short length of stroke a nonreturn element with sealing separates the high pressure chamber from the reserve chamber. The transmission is loss-free in a set ratio without interfering oscillations. Electrical signal processing systems control the sequence in the pneumatic part. Due to the high flow speed the converted energy is quickly provided to the hydraulic consumers. With the aid of the hydraulic intensifier, hydraulic consumers that require higher pressure can be actuated by a lower pneumatic ingoing pressure that way. The area ratio of piston and plunger affect the increase in pressure in the hydraulic intensifier. The increase of pressure during the stroke is depending on the force that the pressure inlet. The back stroke is made trough de-aeration of the compressed air part. Single-acting Operating condition: Before operation the hydraulic intensifier is to be filled with hydraulic oil and must be deaerated in the hydraulic system. In order to check the oil level, the hydraulic intensifiers are equipped with an oil level window as standard. An electrical oil level control is available as accessory part (see page 2). This electrical control automatically detects a minus and with that makes oil level control in the hydraulic part easier. The oil volume of the driving cylinder is pushed backwards until the non-return element opens. Compensation of the pressurizing medium is made automatically. For that, the piston is pulled by a magnet into its end position (up to pneumatic-piston Ø up to 140 mm). Webcode: 043004 Other designs are available on request Connections: There is no oil loss by leakage. Secured by non-return element and sealing losses are always directed into a reserve chamber. That makes the ingress of air impossible. In order to shorten compensation time we recommend to provide a constant feed pressure to the hydraulic intensifier of 0.5 to 1 bar. For those types with pneumatic piston Ø > 140 mm this is mandatory as these to not have a magnetically controlled back stroke. Operating medium: Compressed air, filtered, oiled or unoiled Hydraulic oil, ISO VG 32, DIN 51 524 Operating pressure: Double-acting In order to increase driving power and speed, the hydraulic intensifier can be operated double-acting. In doing so, feed pressure is to be 0.5 to 12 bar. With this procedure it is prevented to cause under pressure in pipes and driving cylinder. In addition a quick aeration valve can be implemented. Operating temperature: 15° C up to 80° C, with electrical oil level control up to 60° C Fast loss-free pressure transfer No interfering oscillations No underpressures in the system Application example: Leakage-free operation with reserve With oil level control Hydropneumatic drive with hydraulic intensifier Hydropneumatic cylinder Hydraulic intensifier Throttle check valve Check valve Pneumatic directional valve 430-4 / 02-13 *Subject to change without notice, compare issue no. at www.hydrokomp.de.
