Amanyathelo amathandathu okukufundisa ukutshintsha ngokulula isihluzi somoya we-excavator:

Isihluzo somoya we-excavator yenye yezona mveliso zibaluleke kakhulu ezixhasayo zenjini. Ikhusela i-injini, ihluza amasuntswana othuli oluqinileyo emoyeni, inika umoya ococekileyo kwi-injini, ikhusela ukuguga kwe-injini okubangelwa luthuli, kwaye iphucula ukuthembeka kunye nokuqina kwe-injini. Isini sinendima ebalulekileyo.

Xa umbhobho wokuthatha okanye into yokucoca ivalwe bubumdaka, oko kuya kukhokelela kumoya ongonelanga wokungena, okubangela ukuba injini yedizili yenze isandi esiluthuntu xa isantya, ukusebenza okubuthathaka, ukunyuka kwamaqondo obushushu bamanzi, kunye negesi ephumayo engwevu-emnyama. Ukuba indawo yokucoca umoya ifakwe ngokungafanelekanga, umoya oqulethe ubuninzi bokungcola awuyi kudlula kwindawo yokucoca i-filter element, kodwa uya kungena ngokuthe ngqo kwi-cylinder ukusuka kwi-bypass.

Ukuze ugweme le nto ingentla, isihluzo kufuneka sifakwe ngokwemigaqo, kwaye imilinganiselo yokugcinwa kwemihla ngemihla kufuneka iqiniswe. Xa i-excavator ifikelela kwixesha lokugcinwa elichaziweyo, ngokubanzi isihluzo esirhabaxa sitshintshwa ngeeyure ezingama-500, kwaye isihluzo esihle sitshintshwa ngeeyure eziyi-1000. Ke umbuzo ngulo, ngawaphi amanyathelo aqhelekileyo okutshintsha isihluzo somoya?

Inyathelo loku-1: Xa injini ingaqaliswanga, vula umnyango wecala elingasemva lekhabhi kunye nesigqubuthelo sokugqibela sesixhobo sokucoca, susa kwaye ucoce ivalve yerabha yokucoca irubha kumgangatho osezantsi wendlu yokucoca umoya, khangela ukuba umphetho wokutywina ukhona. igugile okanye hayi, kwaye ubuyisele ivalve ukuba kuyimfuneko. (Qaphela ukuba akuvumelekanga ukususa isihluzo somoya ngexesha lokusebenza kwe-injini. Ukuba usebenzisa umoya ocinezelweyo ukucoca isihluzo, kufuneka unxibe izibuko ezikhuselayo).

Inyathelo lesi-2: Hlukanisa into yokucoca umoya yangaphandle kwaye ujonge ukuba into yokucoca yonakele. Ukuba kunjalo, nceda uyibuyisele kwangethuba. Sebenzisa umoya woxinzelelo oluphezulu ukucoca isihluzo somoya wangaphandle ukusuka ngaphakathi ngaphandle, uqaphele ukuba uxinzelelo lomoya akufanele ludlule i-205 kPa (30 psi). Irradiate ngaphakathi kwesihluzo sangaphandle ngokukhanya. Ukuba kukho nayiphi na imingxunya emincinci okanye iintsalela ezibhityileyo kwindawo yokucoca ecociweyo, nceda buyisela isihluzo.

Inyathelo lesi-3: Qhoboza kwaye ubeke endaweni yesihluzo somoya sangaphakathi. Qaphela ukuba isihluzo sangaphakathi siyinxalenye yexesha elinye, nceda ungasihlambi okanye usisebenzise kwakhona.

Inyathelo lesi-4: Sebenzisa iraphu ukucoca uthuli olungaphakathi kwindlu. Qaphela ukuba akuvumelekanga ukusebenzisa umoya ophezulu wokucoca.

Inyathelo lesi-5: Fakela ngokuchanekileyo izihluzi zomoya zangaphakathi nangaphandle kunye nesiphelo sezihluzi zomoya, uqinisekise ukuba amanqaku otolo akwiminqwazi aphezulu.

Inyathelo lesi-6: Isihluzo sangaphandle kufuneka sitshintshwe kanye emva kokuba isihluzo sangaphandle sicocwe ngamaxesha angama-6 okanye ixesha lokusebenza lifikelela kwiiyure ezingama-2000. Xa usebenza kwiindawo ezinzima, umjikelo wokugcinwa kwesihluzo somoya kufuneka ufinyezwe ngokufanelekileyo. Ukuba kuyimfuneko, i-oyile yokuhlamba i-pre-filter ingasetyenziswa, kwaye ioli ngaphakathi kwe-pre-filter kufuneka itshintshwe rhoqo kwiiyure ezingama-250.
