Application example

Electrical slip ring transmitter instead of many fluid lines

HYDROKOMP is forming a space saving and labour saving path. Independent of the number of clamping stations, the multi-functional rotary coupling MFD transfers the pressure and return of a fluid medium via only two channels. In addition it delivers electronic control signals to the fixture. More media lines, eg. for air or water, are optionally available for the user.

Hydraulically driven fixtures on rotary tables are normally activated directly over the rotary couplings. In addition every clamping station requires one or more hydraulic lines. The length and installation space of the rotary couplings are increased corresponding on the number of clamping stations.




With the HYDROKOMP solution an electrical slip ring transmitter replaces to a large extent the fluid lines. The work table or the fixture accepts the valve block for the clamping equipment. Instead of 6 to 24 lines, with the MFD only two lines supply all valve blocks. To control the valve blocks or the clamping stations, the slip ring transmits the electronic control signals. Their amperage can be up to 2 A and voltages up to 24 V. In this way the user saves installation space and line and leak labour. On customer request the rotary couplings can also be produced for Profibus and other applications.

HYDROKOMP produces mainly MFD rotary couplings with nominal diameters between 40 mm and 200 mm. The hydraulic pressure can be up to 500 bar and the gas or air pressure 10 bar. The rotary couplings are manufactured out of corrosion protective materials such as brass or corresponding steels.

Typical applications are welding of lorry and construction machine parts, mechanical processing of large components in rotary indexing machines or surface treatment and cleaning in several work stations. The small installation length of the rotary coupling MFD makes it easier to convey application-specific other media, eg. purging gas during welding or coolant lubrication during the machining process.
