Synchronous clutch couplings

Synchronous clutch couplings (see Fig. P-55) are required today in a wide range of applications. These include, but do not exclusively consist of, applications in the following. 

This OEM has three main product lines of synchronous clutch couplings. See Fig. P-56. 

It is also possible to provide each product of the synchronous clutch couplings with very distinctive features. Figure P-57 gives some examples of combination possibilities of different features available for two of the designs. Type MS and Type HS. 

Based on the foregoing, the designation of a particular type of synchronous clutch coupling gives the following information ... 

M = Mecbanical automatic disengagement H = Hydraubc disengagement S - Synchronous clutch coupling... 

Synchronous clutch coupling (see Figs. P-58 and P-59) of the type HS-85 (the information soxuee s model designation) can be installed in a power plant between the gas turbine and alternator.

The synchronous clutch coupling of the type MS-85-S is mounted between the gas turbine (power turbine only) and the alternator. In this case the MS-type coupling is provided with the S-feature, which means that the coupling will behave like a rigid coupling when engaged. 

Free-standing synchronous clutch couplings type MS-... -E (this information source s model designations). Encased synchronous clutch couplings (see Fig. P-65) have been developed for installations where complete isolation of the driving machine is required for on-site maintenance while the driven machine continues to rotate. Typical applications for the encased clutches are fan drives with two driving machines. 

Figures P-66 and P-67 show a t5 ical example of synchronous clutch coupling application in the field of combined cycle technology in a chemical plant. Steam is generated by a conventional boiler which can be used for the process technology or power generation. K steam is available the steam ttu-bine will be started and automatically coupled to the alternator.

Optional synchronous clutch couplings to connect or disconnect gas turbine and generator fully automatically when the generator is running as a synchronous condensor.
