Kutheni i-Piston ye-150KVA yeGenereyitha iSete ngokulula ukuba ingaphumeleli

I-Piston yinxalenye encinci ye-150KVA yeseti yejenereyitha yedizili, kodwa yenye yezona ndawo zibalulekileyo zejenereyitha yedizili.Ngenxa yokuba imeko-bume yayo yokusebenza imbi ngokwentelekiso, idla ngokuba neengxaki ezinjalo.Makhe sijonge ukuba yintoni ebangela ukusilela kwepiston.

Ngexesha lokusetyenziswa kwe Iseti yejeneretha ye-150KVA , iindawo ezigugile ngokulula zepiston ziyi-groove ye-ring, ilandelwa yi-skirt kunye ne-pin hole.Kuhlala kukho imijelo emininzi yeringi kwipiston, kodwa i-ring groove ekufutshane negumbi lokutsha yeyona isengozini yokunxitywa.Xa i-groove ye-ring igugile kakhulu, i-high-temperature kunye ne-high-pressure gas iya kungena kwi-crankcase kwaye i-oyile ye-injini iya kungena kwigumbi lokutshisa.Emva kokuba ipiston yonakaliswe, ingahlolwa ngokubanzi ngokujongwa kunye nesigwebo.Xa umbhobho wokukhupha we-injini ye-diesel ukhupha umsi oluhlaza okanye amandla ehla, uninzi lweempazamo zenzeka kwi-ring groove okanye kwikomityi yepiston.Xa i-injini ye-diesel ingasebenzi, isandi sokuvuza komoya kwi-crankcase siyavakala.Kunzima ukulungisa ipiston.Xa ipiston inxitywe kakhulu, ngokuqhelekileyo itshintshwa ngepiston entsha yemodeli efanayo.

A.Izizathu zomphezulu weplagi ye-injini ukubetha intloko yesilinda.

1.Ngexesha lokugcinwa okanye indibano, ngengozi yehla izikrufu ezincinci, iinati okanye izikrufu kumbhobho wokungenisa okanye ipiston.Okanye ufunxe kwi-cylinder ngexesha lokufunxa, okanye i-gasket encinci ibanjwe phantsi kwentloko ye-cylinder.Xa ufaka intloko ye-cylinder, ayizange ibonwe ukuba ihlale kwigumbi lokutsha, kwaye kwakukho ingxolo engaqhelekanga emva kokuqala injini, ebangela ukuba isithsaba sepiston singqubane nentloko ye-cylinder.

2.Umonakalo kwintambo yokudibanisa iya kubangela ukuba i-piston ithinte intloko ye-cylinder.Olu hlobo longquzulwano lungquzulwano lwe-inertial kwaye alubangelwa yintonga okanye ipiston edibeneyo.Ngoko ke, xa ujika i-flywheel, i-piston ayinakufunyanwa ichukumisa intloko ye-cylinder.Inokuvakala kuphela xa i-diesel generator isebenza (isandi siyanda ngokunyuka kwesantya esijikelezayo, kwaye isandi sikhanya ngesantya esiphantsi).

3.Xa ufaka i-cap yokudibanisa i-cap, faka i-cap ye-bearing reverse okanye ufake enye i-caps yokudibanisa ngokungalunganga.Nangona i-screw iqinisiwe, i-Bush ise-oval (umzimba wentonga yokudibanisa kunye nesigqubuthelo sicutshungulwa ngababini kwaye asinakutshintshwa).I-inertia yokujikeleza ibangela ukuba ipiston ibethe intloko ye-cylinder, okukhokelela kwisandi esikhanyayo, esinqabileyo nesiqinileyo.Kusekho ingxolo emva kokunqunyulwa kweoli, engenzi buthathaka, kwaye intloko ye-cylinder ishukuma kakhulu.Ngoko ke, ingqalelo ekhethekileyo kufuneka ihlawulwe kule ngongoma ngexesha lokugcinwa.

4.Emva kokuba i-bolt yokudibanisa ikhululiwe, iya kubangela ukuba i-piston idibanise nentloko ye-cylinder.Iibholiti ezifanelekileyo ziya kukhethwa kwaye ziqiniswe njengoko kufuneka.Akuvumelekanga ukusebenzisa iibholiti ezindala.

B. Ipiston yokuhlikihla isilinda.

Umphezulu wepiston urhabaxa ngenxa yokukhuhlana okomileyo;Xa ijenereyitha yedizili ikhatshwa kukunkqonkqoza kancinane kwi-cylinder, iidiphozithi zesinyithi zenziwe kumphezulu wepiston.Ngeli xesha, ukuba ayilungiswanga ngexesha, i-piston kunye ne-cylinder liner ziya kuvalwa.

1. Ukusebenza okugqithisiweyo kwejenereyitha ye-diesel kunye neengxaki kwinkqubo yokupholisa ifilimu yeoli eyonakalisiweyo, okubangelwa ukutsalwa kwe-cylinder.

2. Ioli yokuthambisa incinci kakhulu ukuba idlale indima esebenzayo kwi-lubrication, okanye ukungaphumeleli kwenkqubo yokuthambisa kukhokelela ekwandeni kwe-coefficient ye-friction phakathi kwe-piston kunye ne-cylinder liner, okubangelwa ukutsalwa kwe-cylinder.

3. Ulungelelwaniso olungafanelekanga lwexesha lokulayita kwejenereyitha yedizili lubangela ukunkqonkqoza kunye nokonakala kwejenereyitha yedizili, kunye nobushushu obuphezulu kakhulu ijenereyitha yedizili itshabalalisa ifilimu yokukhusela ioli, okubangela ukutsalwa kwe-cylinder.

4. Ukufakwa okungafanelekanga kwepiston okanye ukufakwa okungafaniyo kwepiston kunye ne-cylinder liner, kunye nokukhutshwa okukhulu okanye okuncinci kakhulu kunokukhokelela ekutsaleni i-cylinder.

5. Isihluzo somoya, i-oyile yokucoca ioli kunye ne-fuel filter ye-diesel generator set ayitshintshi kwaye ihlambuluke ngexesha, elingcolisa indawo yokusebenza ye-cylinder kwaye ikhokelela ekutsaleni i-cylinder.

6. Ukugoba kwentonga kutshintsha indlela ehamba ngayo yepiston, okubangela ukutsalwa kwe-cylinder.

7. Umsesane wepiston ubambekile kwaye umsesane wepiston wophukile, okukhokelela ekutsalweni kwesilinda.

8. Kukho i-carbon eninzi kakhulu kwisethi ye-generator, kwaye i-carbon ewileyo ingena kwibhloko ye-cylinder, okubangelwa ukutsalwa kwe-cylinder.

Ngaphezulu zizizathu zokungaphumeleli kwepiston ye-150KVA generator, xa sisebenzisa isethi ye-diesel generator, ukuba sifumene naziphi na iimpazamo, kufuneka simise umatshini ukwenza uhlolo kunye nokusombulula iimpazamo ngexesha.Ngoko oko kunokunciphisa umonakalo womatshini.
