40. Ndezvipi zvakanakira vatengi kutenga self-kutanga makabati asi kwete kutenga?
A: 1) Kana kutadza kwemagetsi kuchiitika munetiweki yeguta, iyo seti ichatanga otomatiki kuti ikurumidze kufambisa simba rekushandisa nguva;
2) Kana mutsara wekuvhenekera wakabatanidzwa pamberi pemhepo inoshandura, inogonawo kuvimbisa kuti kuvhenekera muimba yekombuta hakukanganisi nekukundikana kwemagetsi, kuitira kuti zvive nyore kushanda kwevashandi.
41. Chiratidzo cheGF cheseti yejenareta yemumba chinorevei?
A: Inomiririra zvirevo zviviri: a) Power frequency jenareta seti inokodzera kuChina general simba 50HZ generator set. B) Domestic jenareta seti.
42. Ko mutoro unotakurwa nejenareta unofanirwa kuchengetedza chiyero chezvikamu zvitatu mukushandisa?
A: Hongu. Kutsauka kukuru hakufaniri kudarika 25%. Chikamu chisipo kushanda chinorambidzwa zvachose.
43. Ndezvipi zvina zvinorehwa injini yedhiziri ina?
A: Inhalation, compression, basa uye kupera simba.
44. Ndeupi musiyano mukuru pakati peinjini yedhiziri uye injini yepeturu?
A: 1) Kudzvanywa muhumburumbira kwakasiyana. Diesel injini dzinomanikidza mweya panguva yekumanikidza sitiroko chikamu; Injini yepeturu inomanikidza musanganiswa wepeturu nemhepo panguva yekumanikidza sitiroko.
2) Nzira dzakasiyana dzekudzima. Injini dzedhiziri dzinongobatidza moto nekupfapfaidza mafuta edhiziri atomidhi mumagasi anodzvanyirira. Injini dzepeturu dzinobatidzwa nema spark plugs.
45. Ko “mavhoti maviri, matatu masisitimu” anorevei muhurongwa hwesimba?
A: Matikiti maviri anoreva tikiti rebasa uye tikiti rekushanda. Chero basa kana kushanda kunoitwa pamagetsi emagetsi. Matikiti ebasa uye ekushanda anopihwa nemunhu ari pabasa anofanira kutanga atorwa. Mapato anofanirwa kusimudzira nekuvhota. Matatu masisitimu anoreva shift system, patrol yekuongorora system uye yakajairwa michina switching system.
46. Chii chinonzi inonzi three-phase four-waya system?
A: Kune 4 mitsara inobuda yejenareta seti, iyo 3 ndiyo mitsetse yemoto uye 1 ndeye zero mutsara. Mhepo iri pakati pemitsara ndeye 380V. Nharaunda pakati pemutsara wemoto uye zero mutsara ndeye 220 V.
47. Zvakadini nezvikamu zvitatu zvedunhu pfupi? Migumisiro yacho ndeipi?
A: Pasina chero kuremerwa pakati pemitsetse, yakananga pfupi dunhu ipfupi-chikamu chetatu. Migumisiro yacho yakaipa, uye migumisiro yakakomba inogona kukonzera kuparadzwa kwemuchina uye rufu.
48. Chii chinonzi back power supply? Ndeipi miuyo miviri yakakomba?
A: Simba rekupa kubva kune wega-yakapihwa jenareta kune network network inonzi reverse magetsi. Pane mhedzisiro mbiri dzakakomba: a)
Hapana kukundikana kwemagetsi kunoitika mumambure eguta, uye simba remagetsi eguta network uye simba rejenareta rakazvimiririra harina kuwiriraniswa, izvo zvinoparadza seti. Kana huwandu hwejenareta hwekuzvipa hwakakura, network yeguta ichazununguka zvakare. B)
Municipal power grid radzimwa uye riri kugadziriswa. Majenareta ayo anopa simba kumashure. Ichakonzera kuti vashandi vedhipatimendi rekugadzirisa magetsi vafe.
49. Sei mugadziri achifanira kunyatsoongorora kana mabhaudhi ese ekugadzirisa ari muchimiro chakanaka asati agadzirisa? Yese mitsetse yekubatanidza yakamira?
A: Mushure mekutakura kure-kure, dzimwe nguva hazvidziviriki kuti seti isunungure kana kudonhedza mabhoti uye mitsetse yekubatanidza. Iyo yakareruka iyo debugging, inorema kukuvadza kumushini.
50. Simba remagetsi nderopi? Ndeapi maitiro e AC?
A: Simba remagetsi nderechipiri simba. AC inoshandurwa kubva kumagetsi simba uye DC inoshandurwa kubva kumakemikari simba. AC inoratidzwa nekusakwanisa kwayo kuchengeta. Iko zvino yave kuwanikwa kushandiswa.
51. Ndeapi mamiriro anogona kusangana nejenareta isati yavhara kune magetsi?
A: Iyo yekutonhora kwemvura seti uye tembiricha yemvura inosvika 56 degrees Celsius. Air-cooled set uye muviri zvinopisa zvishoma. Voltage frequency yakajairika pasina mutoro. mafuta emafuta akajairika. Ipapo chete ndipo panogona kuvharwa simba.
52. Ndeipi kutevedzana kwemitoro mushure mesimba-pa?
A: Mitoro inotakurwa kubva kuhombe kuenda kudiki.
53. Ndeipi kutevedzana kwekuburitsa kusati kwadzima?
A: Mitoro inodururwa kubva kudiki kusvika kuhombe uye inovhara shure.
54. Sei tisingakwanisi kudzima uye kuenderera mberi nemutoro?
A: Kuvhara nemutoro ndiko kumira kwechimbichimbi.
