Description
本願は、2022年5月10日に出願された特願2022-77565号に対して優先権を主張し、その内容をここに援用する。
図1に示すように、ガスタービン1は、圧縮機10と、燃焼器20と、タービン30と、を備えている。
続いて、図4と図5を参照して、ガスタービン1のメンテナンス方法について説明する。このメンテナンス方法は、上述した入口案内翼40、及び可変静翼60に用いられるアクチュエータ43のローテーション(交換)に関する方法である。
ここで、ガスタービン1をメンテナンスする上では、上述のアクチュエータ43の動作の安定性を確保することが肝要である。アクチュエータ43を運用する上では、電気系統や内部のボールネジ等を定期的に点検・交換する必要がある。しかしながら、入口案内翼40と可変静翼60とでは、アクチュエータに要求される性能要件が異なっている。このため、これら入口案内翼40と可変静翼60との間でアクチュエータ43を相互に交換することは難しかった。その結果、メンテナンスコストが増大してしまうという課題があった。そこで、本実施形態では、入口案内翼40と、可変静翼60とにそれぞれ取り付けられるアクチュエータ43の仕様を共通化している。具体的には、より大きな推力が必要とされる可変静翼60側にアクチュエータ43の仕様を揃えている。これにより、入口案内翼40と可変静翼60との間でアクチュエータ43をローテーションしながら運用することが可能となるため、コストダウンを図ることができる。
以上、本開示の実施形態について図面を参照して詳述したが、具体的な構成はこの実施の形態に限られるものではなく、本開示の要旨を逸脱しない範囲の設計変更等も含まれる。
例えば、上記実施形態では、3つのアクチュエータ43が同一のガスタービン1のみに順次適用される例について説明した。しかしながら、型式が共通するガスタービン1同士の間では、アクチュエータ43を互いに共通化して用いることも可能である。
