One- or Multi-port Rotary Distributors
The rotary distributors for company Rekofa are mainly used in automobile cranes, vehicle platforms, fire fighting vehicles, agitating machines, step positioners, revolving tables and special machines in connection with slip ring bodies.
Standard Rotary Distributors 2 and 4 Channels
Operating data:
max. pressure: 350 bar
max. periphery speed: 1,5 m/s
Two separately arranged roller bearings provide precise guidance to the rotor. This four-port distributor is used where several with different media, pressures or flows impinged lines shall be connected to a turning machine part.
Special Rotary Distributor 44 Channels
Application:
Rotary distributor for company ELHA for a 4-station special machine, fitted vertically into a revolving table to control four independently operating clamping devices.
pressure: 300 bar
media: hydraulic oil
Special Rotary Distributor 24 Channels
Application:
The rotary distributors for company Krauss-Maffei are used in injection moulding machines to produce so-calles multi-colour/multi-component moulds. These moulds consist of different colours or materials and are manufactured in one operation process. To achieve this in one operation process, one half of the tool has to be cycled at 120°/180° or 360°. That means a second material is sprayed onto the first or a third onto the second with each cycle.
Although the tool cycles forward or backward or turns over 360°, the mould nests have to be continuously supplied with cooling water. Pneumatically and/or hydraulically operated movements and processes have to be carried out on the tool. In order to supply such energies to the turning tool rotary distributors are an imperative need. Media/Pressure: water / 15 bar, hydraulic oil / 150 bar
Special Rotary Distributor 12 Channels
Application:
Rotary distributor for a laddle turret used in a continuous slab casting plant for company SMS Concast, USA
Media/Pressure: water-glycol / 210 bar, Argon / 210 bar, air / 210 bar
Special Rotary Distributor 14 Channels
Application:
Multi-channel rotary distributor for company MAN in the pivot of the ladle turret. The heart in the production chain from the raw steel to the rolled product for the modern continuous casting technology. Intermittend operation with +/- 180° swivel angle for continuous casting operation.
Media/Pressure: mineral oil / 250 bar, grease / 250 bar, compressed air / 20 bar, Argon / 20 bar
Special Rotary Distributor 14 Channels
Application:
Rotary distributor with double sealed ring channels and control connections to control the seals. Two ball bearings provide for stable and maintenance-free bearing of the stator in the rotor.
Media/Pressure: mineral oil / 250 bar, phosphat ester / 250 bar, grease / 250 bar, compressed air / 16 bar, Argon / 26 bar
