Izimbangela Zokulimala Kwezihlahla Ezithwele Amasethi Ejeneretha

Yini ebangela ukulimala kwezihlahla ze-generator set?Umkhiqizi wejeneretha kadizili uyakuphendulela.

1. Ngesikhathi sokusebenza okuvamile kwenjini kadizili, kunegebe phakathi kwejenali ye-crankshaft kanye nesihlahla esithwalayo futhi kukhona ifilimu kawoyela ukwenza uketshezi lokuthambisa.Ngale ndlela, ukulahlekelwa ukungqubuzana kuncane, futhi ukushisa okukhiqizwa ukungqubuzana nakho kuncane.Ukushisa kuthathwa ngamafutha, futhi izinga lokushisa lokusebenza lijwayelekile.

2. Uma isihlahla esizalayo se ijeneretha kagesi ithintana ngqo nejenali ukuze yenze isimo sokungqubuzana okomile ngokwengxenye, ukusetshenziswa kwamandla okungqubuzana kuzokhuphuka kakhulu, futhi inani elikhulu lokushisa okungqubuzanayo lizokhiqizwa futhi lihlakazwe isihlahla esithwalayo.Nokho, ukushisa okuthathwa ngamafutha akukuningi, ukushisa kunqwabelana egobolondweni elithwalayo, futhi izinga lokushisa lilokhu likhuphuka.Lapho izinga lokushisa lendawo encibilikayo ye-alloy endaweni yegobolondo elithwele, ingaphezulu legobolondo elithwalayo lizoqala ukuncibilika lize lishise, okubangele ukuthi injini yedizili yehluleke ukusebenza.

3. Izinga lokushisa likawoyela liphezulu kakhulu noma liphansi kakhulu

A. Uma izinga lokushisa likawoyela liphansi kakhulu, i-viscosity yamafutha okugcoba iphezulu kakhulu futhi uketshezi lubi.Ikakhulukazi esimweni sokuqala esibandayo, inani lamafutha angena ku-crankshaft lincane, okulula ukwenza isihlahla esithwalayo kanye nejenali ye-crankshaft ixhumane ngokuqondile, futhi isheshise ukuguga nokulimala kokuthwala.

B. Uma izinga lokushisa likawoyela liphezulu kakhulu, i-viscosity yamafutha okugcoba izoba phansi kakhulu, futhi amandla efilimu kawoyela ayoba buthakathaka, okuholela ekunciphiseni kobukhulu befilimu kawoyela, futhi kulula ukubangela ekuqaleni. ukuguga nokulimala kwesihlahla esithwalayo.Ukuze welule ngokugcwele impilo yesevisi ye-bearing, izinga lokushisa elivamile kufanele ligcinwe ngaphakathi kwebanga elingu-95~105℃.Yiqiniso, lolu hlu lungashintsha ngenxa yohlobo oluhlukile lwenjini ye-diesel.

C. Izinga likawoyela wokugcoba liphansi.Isethi yejeneretha isebenzise uwoyela wokugcoba osezingeni eliphansi noma uwoyela wokugcoba mbumbulu ngesikhathi sokusetshenziswa.Uma izinga likawoyela wokugcoba lingahlangabezani nezidingo zomkhiqizi wenjini ye-diesel, kuzophinde kubangele ukuthi injini ye-diesel ikhiqize ukwehluleka ukuvutha kwehlathi.

4. Ukugunyazwa komhlangano wokuthwala okungafanele

A. Ukuze kuthuthukiswe isimo sokugcotshwa kwamabheringi amakhulu enjini kadizili ekhona futhi kuvinjwe umonakalo wokusha, imvume phakathi kwebheringi nejenali ye-crankshaft kufanele ilawulwe ngokuqinile ngokuhambisana nezidingo zemanuwali yokusebenza kwenjini kadizili.

B. Uma ushintsha isihlahla esithwalayo, hlola ukuzungeza kanye nobugqila bejenali ye-crankshaft.Uma idlula umkhawulo, kufanele ibe phansi ukuze igweme ukunciphisa indawo yokuxhumana yejenali kanye nesihlahla esithwalayo futhi ikhulise ingcindezi yendawo ngayinye yeyunithi.

C. Ngaphezu kwalokho, i-axial clearance ye-crankshaft kufanele ilawulwe, futhi uma ukugqoka ngokweqile, kufanele kulungiswe ngesikhathi.

5. Ukuwohloka kwamafutha

A. Ngokuvamile, ngesikhathi kusetshenziswa uwoyela wokugcoba, ngenxa yokugqokwa kwama-cylinder enjini kadizili namasongo e-piston, kanye noshintsho ezikhaleni zokuvula indandatho yepiston nezindawo zokuvula, izinga lokushisa eliphezulu kanye nengxubevange enamandla evuthayo engena ku-crankcase iyaqhubeka. ukwanda.Lokhu akubangeli nje ukuthi izinga lokushisa lamafutha okugcoba likhuphuke, kodwa futhi kusheshisa i-oxidation kanye ne-polymerization yamafutha okugcoba.

B. Ngesikhathi esifanayo, kuhambisana nokuxutshwa kwemikhiqizo evuthayo yenjini ye-diesel, ukuxuba uthuli lwangaphandle, imfucumfucu yokugqoka insimbi, kanye nokusetshenziswa kwezithasiselo emafutheni okugcoba, ukuwohloka nokuwohloka kwamafutha okugcoba kuyashesha kakhulu.Lokhu akugcini nje ngokukhuphula ukuguga nokugqwala kwe-friction pair engxenyeni yokugcoba yenjini ye-diesel, kodwa futhi kubangela isizathu esiyinhloko sokushiswa kwe-bearing.

6. Ukuthwala inkinga yekhwalithi

Uma kusetshenziswa izinto ezisezingeni eliphansi, ukumelana nokushisa okuphezulu kanye nomthamo wokuzala wesihlahla esithwalayo akwanele, noma ngabe ukucindezela kwamafutha kuyinto evamile futhi umthamo wamafutha wanele, kuzobangela ukuhluleka kokushiswa kwehlathi.Ngakho-ke, lapho uthenga generator diesel, kufanele sinake izinga injini diesel.

7. Ukudlidliza kakhulu ngesikhathi sokusebenza kwenjini kadizili

A. Ngenxa yokulimala kokumuncwa noma ezinye izizathu, injini kadizili idlidliza kakhulu phakathi nokusebenza.

B. Kungenzeka futhi ukuthi i-elementi edambisayo ye-crankshaft yenjini ye-diesel yonakalisiwe, okubangela ukuba u-crankshaft we-diesel injini idlidlize kakhulu;ngemva kwesikhathi eside sokusebenza, kungase kubangele ukuba igobolondo elithwalayo lixege, kubangele ukushiswa kwehlathi noma ukwehluleka ukushelela kwesihlahla.

Ngamafuphi, asikwazi ukunakekela intengo yomkhiqizo kuphela, ikhwalithi yomkhiqizo nayo ibaluleke kakhulu, khona-ke ukugcinwa okuvamile nakho kubaluleke kakhulu ngemva kokusebenzisa. amajeneretha edizili .
