Buhar t\u00fcrbini, buharda depolanan enerjiden mekanik i\u015f elde etmek i\u00e7in bir cihazd\u0131r.

T\u00fcrbin T\u00fcrleri<\/span><\/strong><\/h3>\n

\u0130ki ana t\u00fcrbin tipi vard\u0131r, ‘impuls’ ve ‘tepki’. \u0130simler, t\u00fcrbin \u00e7ark\u0131n\u0131 d\u00f6nd\u00fcrmek i\u00e7in kanatlara etki eden kuvvet tipini ifade eder.<\/span><\/p>\n

D\u00fcrt\u00fc<\/span><\/strong><\/p>\n

\u0130tki d\u00fczenlemesi, bir kanat halkas\u0131n\u0131 takip eden bir noz\u00fcl halkas\u0131ndan olu\u015fur. Y\u00fcksek bas\u0131n\u00e7l\u0131, y\u00fcksek enerjili buhar, memede daha d\u00fc\u015f\u00fck bas\u0131n\u00e7l\u0131, y\u00fcksek h\u0131zl\u0131 bir buhar jetine geni\u015fletilir. Bu buhar jeti, itme kanatlar\u0131na y\u00f6nlendirilir ve farkl\u0131 bir y\u00f6nde ayr\u0131l\u0131r.<\/span><\/p>\n

De\u011fi\u015fen y\u00f6n ve dolay\u0131s\u0131yla h\u0131z, esas olarak t\u00fcrbin kanatlar\u0131n\u0131n d\u00f6nme y\u00f6n\u00fcnde etki eden itici bir kuvvet \u00fcretir. T\u00fcrbin milinde yaln\u0131zca \u00e7ok k\u00fc\u00e7\u00fck bir itme kuvveti vard\u0131r.<\/span><\/p>\n

Reaksiyon<\/span><\/strong><\/p>\n

Reaksiyon d\u00fczenlemesi, mahfazaya tutturulmu\u015f bir sabit kanat halkas\u0131ndan ve rotor \u00fczerine monte edilmi\u015f bir dizi benzer kanattan, yani hareketli kanatlardan olu\u015fur. B\u0131\u00e7aklar, bir a\u011f\u0131zl\u0131k gibi buhar h\u0131z\u0131n\u0131 art\u0131ran daralan bir ge\u00e7it olu\u015fturacak \u015fekilde monte edilmi\u015f ve \u015fekillendirilmi\u015ftir.<\/span><\/p>\n

Kanat \u00fczerindeki h\u0131zdaki bu art\u0131\u015f, kanat d\u00f6n\u00fc\u015f y\u00f6n\u00fcnde ve ayr\u0131ca t\u00fcrbin ekseni boyunca bile\u015fenleri olan bir reaksiyon kuvveti \u00fcretir. Y\u00f6n de\u011fi\u015fikli\u011finin bir sonucu olarak buhar\u0131n h\u0131z\u0131nda da bir de\u011fi\u015fiklik olur ve bu tip b\u0131\u00e7aklama ile itme kuvveti de \u00fcretilir. Bu kanat d\u00fczenlemesi i\u00e7in daha do\u011fru terim “impulse-reaksiyon”dur.<\/span><\/p>\n

Bile\u015fik<\/span><\/strong><\/p>\n

Bile\u015fik olu\u015fturma, bir t\u00fcrbin arac\u0131l\u0131\u011f\u0131yla buhar bas\u0131nc\u0131n\u0131n veya h\u0131z de\u011fi\u015fiminin iki veya daha fazla a\u015famaya b\u00f6l\u00fcnmesidir.<\/span>
\nBir d\u00fcrt\u00fc t\u00fcrbininin bas\u0131n\u00e7 bile\u015fimi, buhar bas\u0131nc\u0131n\u0131 kademeli olarak azaltmak i\u00e7in bir dizi meme ve b\u0131\u00e7ak a\u015famas\u0131n\u0131n kullan\u0131lmas\u0131d\u0131r. Bu, daha d\u00fc\u015f\u00fck veya daha kabul edilebilir buhar ak\u0131\u015f h\u0131zlar\u0131 ve daha iyi bir t\u00fcrbin verimlili\u011fi ile sonu\u00e7lan\u0131r.<\/span><\/p>\n

Bir d\u00fcrt\u00fc t\u00fcrbininin h\u0131z bile\u015fimi, tek bir disk \u00fczerinde birka\u00e7 hareketli kanad\u0131n d\u00fczenlenmesi ile tek bir memenin kullan\u0131lmas\u0131d\u0131r. Hareketli kanatlar\u0131n aras\u0131na, t\u00fcrbin muhafazas\u0131na ba\u011fl\u0131 olan k\u0131lavuz kanatlar yerle\u015ftirilmi\u015ftir. Bu d\u00fczenleme, \u00f6rne\u011fin bir tornistan t\u00fcrbininde kabul edilebilir olan, daha d\u00fc\u015f\u00fck verimlili\u011fe sahip k\u0131sa, hafif bir t\u00fcrbin \u00fcretir.<\/span><\/p>\n

\u0130ki d\u00fczenleme, ‘bas\u0131n\u00e7-h\u0131z bile\u015fimi’ olarak adland\u0131r\u0131lan \u015feyi vermek \u00fczere birle\u015ftirilebilir. Kanat d\u00fczeninin bir sonucu olarak reaksiyon t\u00fcrbini, hem sabit hem de hareketli kanatlardaki buhar h\u0131z\u0131n\u0131 de\u011fi\u015ftirerek sonu\u00e7 olarak kademeli buhar bas\u0131nc\u0131 d\u00fc\u015f\u00fc\u015f\u00fc sa\u011flar. Temel d\u00fczenlemesi bu nedenle bile\u015fik sa\u011flar.<\/span><\/p>\n
