• Induction Noise: Na'urar shan iska ta injin tana haifar da hayaniya yayin da iskar ke saurin jawowa don aikin konewa.

• Hayaniyar Generator (Alternator): Ƙarfin lantarki da ke cikin janareta da kansa, haɗe da fanka mai sanyaya a kan rafinsa, suna haifar da siffa mai saurin mita.

Bincike a kan naúrar 40kW, alal misali, an sami nasarar ganowa kuma an yi niyya ga waɗannan ƙayyadaddun hanyoyin amo, wanda ke haifar da raguwar matakan sauti gabaɗaya.

Fasahar Kula da Surutu na Zamani

Ana wargaza stereotype na "ƙarar ƙarar janareta" ta hanyar ɗumbin fasahar sarrafa hayaniya. Na zamani "silent" ko "super-silent" janareta ba kawai na asali raka'a a cikin akwati; tsarin aikin injiniya ne sosai. Mahimman sabbin abubuwa sun haɗa da:

An ƙirƙira waɗannan guraben don ƙunshe da datse sauti yadda ya kamata.

• Sophisticated Mufflers: Babban aiki masu yin shiru, ko mufflers, suna da mahimmanci don magance ƙaramar ƙarar ƙarar ƙararrawa. An ƙera ɓangarorin su na cikin gida da ɗakunan su don tarwatsawa da ɗaukar igiyoyin sauti kafin su iya tserewa.

Wannan yana ba da damar kwararar iska mai mahimmanci don sanyaya yayin tarko da ɗaukar amo, yana hana shi tserewa kai tsaye zuwa waje.

M vs. Sarrafawar amo mai aiki

Yaƙi da hayaniyar janareta ana yin yaƙi ne ta fuskoki biyu: m da iko mai aiki. Yawancin janaretocin shiru na kasuwanci sun dogara da ingantattun hanyoyin wucewa, waɗanda ke zama tushen rage amo.

• Sarrafa amo mai wucewa: Wannan yana nufin amfani da kayan jiki da sifofi don toshewa, ɗauka, ko datse sauti. Wannan ya haɗa da duk fasahohin da aka ambata a sama-rukunoni, mufflers, masu keɓancewar jijjiga, da baffles mai sauti. Zane na "dubi-Layer iska duct ultra-shuru samar da wutar lantarki" babban misali ne, samun gagarumin amo matakin kasa da 65 dB(A) a 7 mita ta m m zane.

• Sarrafa Noise (ANC): Wannan ƙarin ci gaba ne, tsarin lantarki. Tsarin ANC suna amfani da makirufo don ɗaukar ƙaramar ƙaramar ƙararrawa, na'ura mai sarrafa dijital don tantance shi, da masu magana don samar da siginar "anti-amo" wanda shine ainihin kishiyar (digiri 180 daga lokaci). Lokacin da waɗannan sigina biyu suka hadu, suna soke juna. An yi nasarar amfani da wannan fasaha a cikin jiragen ruwa na alatu, da samun sama da 5 dB na raguwar watsa shirye-shiryen watsa shirye-shirye kuma har zuwa raguwar 23% na ƙarar ƙarar janareta.

Ƙididdige Shuru: Ma'auni na Matsayin Surutu

To, yaya shiru "shiru" yake? Masana'antar tana amfani da ma'aunin decibel (dB(A)) don auna matakan matsin sauti. Don sanya shi cikin hangen nesa, ga wasu ma'auni na gama gari:

• Tattaunawa ta al'ada: ~ 60 dB(A)

• Super Silent Generators: Wasu ƙira na ci gaba, kamar waɗanda ke nuna bututun iska biyu, na iya cimma matakan amo kamar ƙasa da 65 dB (A) a mita 7 yayin aiki mara nauyi.

• Standard Silent Generators: Yawanci suna aiki tsakanin 70-75 dB(A) a mita 7. Bincike akan naúrar 10kW da aka samu a kusa da 70 dB (A) a mita 3 ta hanyar ingantaccen jiyya da amo.

Waɗannan alkaluma sun nuna cewa janareta na shiru na zamani na iya zama maƙwabci mai kyau, yana aiki a matakan sauti kwatankwacin ayyukan yau da kullun.

Ma'auni Mai Mahimmanci: Kula da Surutu vs. Samun iska

Ɗaya daga cikin manyan ƙalubalen injiniya wajen ƙirƙirar janareta na shiru shine sarrafa zafi. Wurin da aka rufe cikakke zai yi shuru amma zai sa injin yayi zafi da sauri. Saboda haka, tasiri dizal janareta amo sarrafawa shine m daidaita aiki tsakanin acoustics da thermodynamics.
