Ukubuka Konke Kokumbozwa Komshini Womshini vs Ukumbozwa Kokumbozwa
Ukuphathwa koketshezi lwezimboni kuncike kakhulu kumaphampu e-centrifugal, ama-agitator, kanye nama-rotary compressor. Iphuzu lapho i-rotary shaft iphuma khona esikhaleni esingaguquki liveza ubungozi obukhulu bokugoba uketshezi. Ukuze baphathe lo mngcele, onjiniyela basebenzisa ubuchwepheshe obubili obuhlukile:izivalo zomshini womshinikanye nezimpawu zokupakisha ezicindezelwe.
Isinqumo phakathi kwalezi zindlela ezimbili zokuvala sinquma isisekelo sokusebenza kwemishini. Nakuba zombili zifeza injongo efanayo eyisisekelo—ukuvimbela ukuphuma koketshezi lwenqubo emgodleni—izimiso zazo zokusebenza, izindleko zomjikelezo wokuphila, kanye nezilinganiso zokusebenza ziyahlukahluka kakhulu. Izivalo zokupakisha zimelela ubuchwepheshe besikhathi esidlule obusekelwe ekuvuzeni okulawulwayo, kantiizimpawu zomshiniinikeza ikhambi lesimanje, elenziwe ngobuchwepheshe obuphezulu elenzelwe ukukhishwa kwegesi okucishe kube yi-zero.
Ukukhetha indlela efanele yokuvala kudinga ukuqonda okujulile ngokuguquguquka koketshezi, imikhawulo yokulawula, kanye namakhono okulungisa. Njengoba izikhungo zezimboni ziqhubeka nokubeka phambili ukusebenza kahle kwamandla kanye nokuthobela imithetho eqinile yezemvelo, ukuthembela kwendabuko ezimpahleni zokupakisha sekushintshile, yize kusalokhu kubalulekile ezisetshenzisweni ezithile ezinzima.
Umehluko obalulekile endleleni yokuvala
Izivalo zomshini zisebenzisa ubuso obubili obuyisicaba kakhulu (obunye bujikeleza nomgodi, obunye bunganyakazi endlini) obucindezelwe ndawonye ngomshini wesipilingi noma we-bellows ukudala isithiyo sefilimu yoketshezi oluncane. Lesi sixhumanisi esiklanywe kahle kakhulu sivimbela ukuphuma koketshezi ngenkathi kunciphisa ukungqubuzana. Ngokuphambene nalokho, izivalo zokupakisha zithembele ezintweni ezilukiwe ezinemicu ezicindezelwe nxazonke zomgodi ngaphakathi kwebhokisi lokugcwala. Umlandeli we-gland uphoqa ukupakisha ngokumelene nomgodi, kuvimbe indlela yoketshezi ngengcindezi ye-brute radial kunokuthembela ebusweni obuyisicaba obuklanywe ngokunemba.
