SefaHTGY300B.4 imapangidwa mwapadera kuti itulutse popukusi mafuta. Ntchito yake yayikulu ndikusefa zosayera mu mafuta ndi kukhalabe aukhondo mafuta kulowa pampu yamafuta. Pampu yampu ya mafuta, ukhondo wa mafuta umagwirizana mwachindunji ndi ntchito yogwira ntchito ndi moyo wa pampu yamafuta.

Seluse htgy300b.4 imagwiritsa ntchito zinthu zakuya kwambiri, zomwe zingagwiritsire ntchito bwino tinthu tokhama mafuta, kuphatikizapo fumbi, tchipisi chachitsulo, zodetsa zachitsulo ndi zosayera. Izi zosefera bwino kumeneku zimatsimikizira kuti ukhondo umafikira mkhalidwe wabwino kwambiri pomwe pampu wamafuta ukayamwa mafuta, potero kupewa kuvala ndi block mkati mwa pampu mafuta.

Magawo ogwiritsira ntchito mkati mwa pumpi yamafuta ali ndi zofunika kwambiri pakuyeretsa kwa mafuta. Kukhalapo kwa SOWNX300B.4 kumachepetsa kuvala kosawoneka bwino m'mafuta amkati mwapampu yamafuta, kukulitsa moyo wa pampu ya mafuta. Izi ndizofunikira kwambiri kuchepetsa mtengo wokonza mphamvu ndikuwonjezera nthawi yogwira ntchito ya zida.

Pug yamafuta imayenera gawo la gwero lamphamvu mu hydraulic dongosolo, ndipo opareshoni yake yokhazikika ndiyofunikira kukhazikika kwa dongosolo lonse. Fyuluta Htgy300b.4 ATHANDIZANI KUGWIRA NTCHITO YA PERF yamafuta yomwe ili pansi pamayendedwe ogwirira ntchito popereka mafuta, kuchepetsa zolephera ndi kutaya zomwe zimayambitsidwa ndi kuipitsidwa ndi mafuta.

Mwachidule, ThesefaHTGY300B.4 Amachita mbali zofunika kwambiri mu dongosolo la kayendedwe wamafuta. Sizingotsimikizira ukhondo wa mafuta, zimalepheretsa kuvala ndi blockpi ya pampu yamafuta, komanso zimatsimikizira kuti pampu wamafuta ndi ntchito yokhazikika ya dongosolo. Mwa kusinthana pafupipafupi ndikusungabe chinthu cha Htgy300.4, chomera champhamvu chimatha kuchepetsa mphamvu yokonza zida za zidazo, kukonza bwino zopanga, ndikuwonetsetsa kupitiliza kwa mphamvu. Chifukwa chake, chidwi chokwanira chimayenera kulipidwa ndikukonza kwazinthu zosefera kuti zitsimikizire ntchito yolimba ya hydraulic dongosolo la chomera.
