Ilimin asali game da wutar lantarki ta ruwa da janareta ta ruwa

1, Raba ƙarfin aiki da kuma matakin janareta mai amfani da ruwa
A halin yanzu, babu wani tsari guda ɗaya da aka tsara don rarraba ƙarfin aiki da saurin janareta na ruwa a duniya. Dangane da halin da ake ciki a China, ana iya raba ƙarfinsa da saurinsa gwargwadon jadawalin da ke ƙasa:
Rarrabawa mai ƙimar iko PN (kw) saurin da aka ƙima NN (R / min);
Ƙaramin gudu, matsakaicin gudu da babban gudu;
Ƙaramin janareta mai amfani da ruwa < 100 750-1500;
Ƙaramin janareta mai amfani da ruwa 100-500 < 375-600 750-1500;
Janareta mai matsakaicin girma 500-10000 < 375-600 750-1500; Babban janareta mai ƙarfin ruwa > 10000 < 100-375 > 375;

2, Tsarin shigarwa na nau'in janareta na ruwa
Tsarin shigarwa na janareta na ruwa yawanci ana tantance shi ta hanyar nau'in injin turbin na ruwa. Akwai nau'ikan da suka fi haka:

1) Tsarin kwance
Injinan samar da wutar lantarki masu tsarin kwance galibi ana amfani da injinan turbine masu motsi. Injinan samar da wutar lantarki masu kwance galibi suna amfani da bearings biyu ko uku. Tsarin bearings guda biyu yana da fa'idodin gajeriyar tsayin axial, ƙaramin tsari da kuma sauƙin shigarwa da daidaitawa. Duk da haka, lokacin da mahimmancin saurin shaft ɗin ba zai iya biyan buƙatun ba ko kuma nauyin bearing ɗin ya yi yawa, ana buƙatar ɗaukar tsarin bearings guda uku. Yawancin na'urorin samar da wutar lantarki na injinan turbine masu amfani da wutar lantarki na cikin gida suna cikin ƙananan na'urori masu girma da matsakaici. Ana kuma samar da manyan na'urori masu tsayi waɗanda ke da ƙarfin 12.5mw. Injinan samar da wutar lantarki na injinan turbine masu aiki da wutar lantarki da ake samarwa a ƙasashen waje ba kasafai ake samun su ba tare da ƙarfin 60-70mw, yayin da injinan samar da wutar lantarki na injinan turbine masu aiki da wutar lantarki da aka ɗora a famfo na iya samun ƙarfin na'ura ɗaya na 300MW.

2) Tsarin tsaye
Tsarin tsaye ana amfani da shi sosai a cikin na'urorin janareta na ruwa na cikin gida. Na'urorin janareta na ruwa na tsaye galibi ana amfani da su ta hanyar Francis ko axial-flow turbines. Tsarin tsaye za a iya raba shi zuwa nau'in dakatarwa da nau'in laima. Ana kiran bearing na turawa na janareta da ke saman ɓangaren rotor a gaba ɗaya da nau'in dakatarwa, kuma bearing na turawa da ke ƙasan na'urar ana kiransa da nau'in laima.

3) Tsarin tubular
Injin samar da injin samar da injin turbin tubular yana aiki ne ta hanyar injin turbin tubular. Injin turbin tubular wani nau'in injin turbin kwarara ne na musamman wanda ke da ruwan wukake masu gyara ko waɗanda za a iya daidaita su. Babban fasalinsa shine cewa an shirya axis ɗin mai gudu a kwance ko a kwance, kuma alkiblar kwararar ta yi daidai da ta bututun shiga da bututun fitarwa na injin turbin. Injin Hydrogenerator yana da fa'idodin tsari mai sauƙi da nauyi mai sauƙi. Ana amfani da shi sosai a tashoshin wutar lantarki waɗanda ke da ƙarancin kan ruwa.

3, Tsarin kayan aikin janareta na ruwa
Injin samar da ruwa na tsaye ya ƙunshi stator, rotor, firam na sama, firam na ƙasa, bearing na turawa, bearing na jagora, mai sanyaya iska da kuma injin maganadisu na dindindin.
