Kanjani a ophephela igesi?

Ophephela wegesi - motor, lapho ngesikhathi operation okuqhubekayo zedivayisi oyinhloko (Rotor) uphendulela umzimba amandla sangaphakathi igesi (kwezinye izimo, umusi noma amanzi) ku umsebenzi plan lokukhanda. Kulesi ketshezi ekusakazeni ukusebenza kuthinta ikhaba esinqunyiwe ku selilonke Rotor, okuholela ezinyakazayo yabo. Njengoba igesi ukugeleza isiqondiso zihlukaniswe ophephela Axial (igesi uhamba zifana kuya eksisi the samanzi) noma osabalalayo (perpendicular ezinyakazayo isihlobo ukuba eksisi efanayo). Kukhona kokubili abangashadile futhi multi-izindlela.

Ophephela igesi ongaqhuba ku ikhaba ngezindlela ezimbili. Okokuqala, kuba inqubo esebenzayo lapho igesi ihlinzekwa endaweni yokusebenza ngesivinini. Kulokhu, ukugeleza igesi ivame ukuhambisa emgceni locondzile futhi imi endleleni yakhe blade lwalugobile lemininingwane bhunkula it, ukuvula ngokwaso. Okwesibili, inqubo ohlobo esisheshayo, lapho izinga igesi okuphakelayo uphansi, Nokho, izingcindezi okusezingeni eliphezulu esetshenziswa. Jet engine uthayiphe ifomu cishe okumsulwa ingekho, isb. K. A ophephela kubo ukwethula ibutho centrifugal okuyinto ethatha ku izindwani, kanye yokusabela force.

Lapho ophephela igesi isetshenziswa namuhla? Umgomo we operation zedivayisi ingasetshenziswa drive ugesi kagesi, compressors, njll ophephela Ukuntuleka lolu hlobo awuthola ezokuthutha (zasolwandle igesi abaphehla ugesi). Uma kuqhathaniswa nge umusi kumakhophi, banalo isisindo elincane nobungako, ngoba akudingeki ngcono kubhayela, ushintsha uba yileli iyunithi.

Ophephela gas ngokushesha isilungele ukusetshenziswa emva kokwethulwa, eba amandla egcwele imizuzu engaba ngu-10, kulula ukugcina, kudinga inani elincane lamanzi lwaluyophola. Ngokungafani yangaphakathi omlilo izinjini, ke ayinayo imiphumela inertial mshini crank. Negesi ophephela isitshalo nohafu esifushane kuka izinjini udizili, futhi abantu abangaphezu kwengxenye isisindo. Idivayisi unekhono ukusebenza fuel eliphansi. Izimfanelo ngenhla avumela izinjini cabanga plan onjalo okunabileko izinkantolo phezu hovercraft futhi hydrofoil.

Igesi ephendulwa injini njengendlela ingxenye main futhi has a inombolo yokuntula abalulekile. Phakathi kwabo uqaphele okusezingeni eliphezulu umsindo ezingeni engaphansi kuka izinjini udizili, ukusebenza kahle, ukusebenza kwesikhathi esifushane ngamazinga ashisa kakhulu (uma isetshenziswa naphakathi gaseous has a lokushisa 1100 ^{° C,} ngesikhathi ukusetshenziswa ophephela kungase kube isilinganiso 750 amahora).

Negesi ophephela kahle incike lapho uhlelo isetshenziswa. Ngokwesibonelo, amadivayisi elisetshenziswa amandla ne lokushisa igesi kokuqala ngenhla 1300 degrees Celsius, nge isilinganiso zlib of air compressor 23 engasekho futhi akukho ngaphansi kuka-17 imisebenzi ezizimele ngesikhathi Coefficient mayelana 38.5%. abaphehla ugesi ezinjalo azizintsha neze yande kakhulu futhi isetshenziswa ngokuyinhloko for ukumboza iphakama umthwalo e phansi isimiso sikagesi. Namuhla, cishe 15 igesi abaphehla ugesi nge namandla angu-30 MW abasebenza ezintweni eziningi ezishisayo izitshalo amandla eRussia. Amayunithi multistage kufinyelelwa ngesilinganiso kakhulu kunalokhu esebenza (azungeze 0.93) ngenxa okusezingeni eliphezulu izici kahle.
