Rateau 3 Stage With Integral Reduction Gear

Description

DESIGN QUALITY & PERFORMANCE ASSURANCES AND ADVANTAGES

Trip and throttle (T&T) valve have advantage of: 
- Less valve stem jam problem.
- Lower steam pressure drops across the governor valve.

- Proven Steam Turbine Generator (STG) design manufactured, assembled & tested in Shinko Hiroshima, Japan.
- All Shinko STG are tested with Live Steam before delivery to customers to ensure quality units are delivered to site. Preventing the need for on-site rectification for new STG units. Shinko also provides opportunity to customers to witness the STG testing in Shinko Factory.
- Rotor is of solid shaft build-up design where rotor wheel is machined to size instead of the conventional shrink-fitted design.
- Shaft sealed using labyrinth packing which are easily maintained and reduce down-time instead of carbon rings that will cause long down-time of STG when doing maintenance (metal spray at worn shaft surface, etc.). Assisted by steam driven steam ejector to prevent condensate from mixing with lubrication oil in non-steam sections.
- Maintenance free Flexible Disc Coupling is implemented. No need to re-grease or oiled.
- Lubrication oil strainer is cleanable type without disposable filter element, thus more economical and environmentally friendly.
