Isikhungo Somkhiqizo

Izinyathelo eziyisithupha zokukufundisa ukushintsha kalula isihlungi somoya se-DAEWOO:

Isihlungi somoya se-excavator singenye yemikhiqizo ebaluleke kakhulu esekela injini. Ivikela injini, ihlunge izinhlayiya zothuli oluqinile emoyeni, inikeza umoya ohlanzekile enjinini, ivimbela ukuguga kwenjini okubangelwa uthuli, futhi ithuthukisa ukwethembeka nokuhlala isikhathi eside kwenjini. Ubulili budlala indima ebalulekile.

Uma ipayipi elingenisayo noma isici sokuhlunga sivinjwe ukungcola, kuzoholela emoyeni onganele, okubangela injini kadizili ukuthi yenze umsindo ongacacile uma ishesha, ingasebenzi kahle, izinga lokushisa lamanzi elikhuphukayo, kanye negesi ephumayo empunga-mnyama. Uma isici sokuhlunga umoya sifakwe ngendlela engafanele, umoya oqukethe inani elikhulu lokungcola ngeke udlule endaweni yokuhlunga yesici sokuhlunga, kodwa uzofaka ngokuqondile isilinda kusuka ku-bypass.

Ukuze ugweme lesi senzakalo esingenhla, isihlungi kufanele sifakwe ngokuvumelana nemithethonqubo, futhi imininingwane yesondlo sansuku zonke kufanele iqiniswe. Lapho umshini wokumba ufinyelela isikhathi sokunakekela esishiwo, ngokuvamile isihlungi esimahhadla siyashintshwa ngamahora angu-500, futhi isihlungi esihle sishintshwa ngamahora angu-1000. Ngakho-ke umbuzo uwukuthi, yiziphi izinyathelo ezijwayelekile zokushintsha isihlungi somoya?

Isinyathelo 1: Uma injini ingakaqalwa, vula umnyango oseceleni ongemuva wekhebhu kanye nesembozo sokugcina sesici sokuhlunga, khipha futhi uhlanze i-valve ye-vacuum yenjoloba esembozweni esingezansi sendlu yesihlungi somoya, hlola ukuthi unqenqema lokuvala lukhona yini. igugile noma cha, bese ushintsha i-valve uma kunesidingo. (Qaphela ukuthi kwenqatshelwe ukukhipha isici sokuhlunga umoya ngesikhathi sokusebenza kwenjini. Uma usebenzisa umoya ocindezelwe ukuze uhlanze isihlungi, kufanele ugqoke izibuko ezivikelayo).

Isinyathelo sesi-2: Hlukanisa isici sokuhlunga somoya sangaphandle futhi uhlole ukuthi i-elementi yokuhlunga yonakele yini. Uma kunjalo, sicela uyishintshe kusenesikhathi. Sebenzisa umoya onomfutho ophezulu ukuhlanza isici sokuhlunga umoya sangaphandle kusukela ngaphakathi nangaphandle, uqaphele ukuthi umfutho womoya akufanele udlule ku-205 kPa (30 psi). Gcoba ingaphakathi lesihlungi sangaphandle ngokukhanya. Uma kukhona izimbobo ezincane noma izinsalela zesihlungi esihlanziwe, sicela ushintshe isihlungi.

Isinyathelo sesi-3: Hlukanisa bese ubuyisela isihlungi somoya sangaphakathi. Qaphela ukuthi isihlungi sangaphakathi siyingxenye yesikhathi esisodwa, sicela ungasigezi noma ungaphinde usisebenzise.

Isinyathelo sesi-4: Sebenzisa i-rag ukuhlanza uthuli ngaphakathi kwendlu. Qaphela ukuthi kwenqatshelwe ukusebenzisa umoya ophezulu wokucindezela ukuhlanza.

Isinyathelo sesi-5: Faka kahle izihlungi zomoya zangaphakathi nezingaphandle kanye namakepisi okugcina wezihlungi zomoya, uqiniseke ukuthi izimpawu zomcibisholo kumakepisi ziphezulu.

Isinyathelo sesi-6: Isihlungi sangaphandle sidinga ukushintshwa kanye ngemva kokuba isihlungi sangaphandle sihlanzwe izikhathi ezingu-6 noma isikhathi sokusebenza sifinyelela emahoreni angu-2000. Lapho usebenza ezindaweni ezinokhahlo, umjikelezo wokunakekelwa kwesihlungi somoya kufanele ufinyezwe ngendlela efanele. Uma kunesidingo, isihlungi sangaphambi kokugeza amafutha singasetshenziswa, futhi amafutha angaphakathi kwesihlungi sangaphambili kufanele ashintshwe njalo emahoreni angama-250.
