Nhanganyaya
Inzwi rinogadzirwa kubva pakufamba kwemvura kuburikidza nevharuvhu.Ndipo chete kana ruzha rwusingadiwi ndipo rwunonzi 'ruzha'.Kana ruzha rwakapfuura mamwe mazinga saka inogona kuve nengozi kune vashandi.Ruzha zvakare chishandiso chakanaka chekuongorora.Sezvo ruzha kana ruzha ruchigadzirwa nekukweshana, ruzha rwakanyanya runoratidza kukuvara kunogona kuitika mukati mevharuvhu.Kukuvadzwa kunogona kukonzerwa nekukwenya pachayo kana vibration.
Kune matatu makuru manyuko eruzha:
-Mechanical vibration
-Hydrodynamic ruzha
-Aerodynamic ruzha
Mechanical Vibration
Mechanical vibration chiratidzo chakanaka chekuipa kwezvikamu zvevharuvhu.Nekuti ruzha rwunogadzirwa kazhinji rwakaderera mukusimba uye kuwanda, kazhinji harisi dambudziko rekuchengetedza vashandi.Vibration idambudziko rakawanda nemavharuvhu anofananidzwa nemavharuvhu ekeji.Mavharuvhu ekeji ane nzvimbo yakakura inotsigira uye saka haanyanyi kukonzera matambudziko ekudengenyeka.
Hydrodynamic Noise
Mhepo yeHydrodynamic inogadzirwa mukuyerera kwemvura.Kana iyo mvura inopfuura nepainorambidzwa uye shanduko yekumanikidza inoitika zvinogoneka kuti mvura inoumba mhute inopfungaira.Uku kunonzi kupenya.Cavitation idambudziko zvakare, uko mabhuru anoumba asi obva adonha.Ruzha rwunogadzirwa kazhinji haruna njodzi kune vashandi, asi chiratidzo chakanaka
yezvinogona kukuvadzwa kukucheka zvikamu.
Aerodynamic Noise
Ruzha rweAerodynamic runogadzirwa nekusagadzikana kwemagasi uye ndiyo honzeri yeruzha.Iwo ruzha anogadzirwa anogona kuve nengozi kune vashandi, uye zvinoenderana nehuwandu hwekuyerera uye kudonha kwekumanikidza.
Cavitation uye Kupenya
Kupenya
Kupenya ndiyo nhanho yekutanga yecavitation.Nekudaro, zvinogoneka kuti kupenya kuitike kwega pasina cavitation inoitika.
Kupenya kunoitika mukuyerera kwemvura kana imwe mvura ichichinja zvachose kuita mhute.Izvi zvinounzwa nekudzikiswa kwekumanikidza kumanikidza mvura kuti ichinje kune gasi.Kuderedzwa kwekumanikidzwa kunokonzerwa nekudziviswa mukuyerera kwemvura kunokonzera kuyerera kwepamusoro kuburikidza nekudziviswa uye naizvozvo kuderedza kudzvinyirira.
Matambudziko maviri makuru anokonzera nekupenya ndeaya:
– Kukukurwa kwevhu
– Kudzikira kugona
Kukukurwa kwevhu
Kana kupenya kunoitika, kuyerera kubva pakubuda kwevhavha inoumbwa nemvura uye mhute.Nekuwedzera kupenya, mhute inotakura mvura.Sezvo kukurumidza kwekuyerera kunowedzera, mvura inoita sezvikamu zvakasimba apo inorova zvikamu zvemukati zvevharuvhu.Velocity yekubuda kwekuyerera inogona kuderedzwa nekuwedzera ukuru hwevhavha yekubuda iyo inogona kuderedza kukuvadzwa.Sarudzo dzekushandisa dzakaomeswa zvinhu ndeimwe mhinduro.Makona mavharuvhu akakodzera pakushandisa uku sezvo kupenya kunoitika kudzika kudzika kure kubva pakugadzirisa nevharuvhu.
Yakaderedzwa Capacity
Kana rwizi rwunoyerera rwukachinja kuita mhute, sepakupenya, nzvimbo yaunogara inowedzerwa.Nemhaka yenzvimbo yakaderedzwa inowanikwa, kukwanisa kwevhavha yekubata kuyerera kwakakura kunogumira.Kuyerera kwekachidzwa izwi rinoshandiswa kana kuyerera kwesimba kwakaganhurirwa nenzira iyi
Cavitation
Cavitation yakafanana nekupenya kunze kwekunge kudzvanywa kunodzoserwa mumhepo inoyerera zvekuti mhute inodzoserwa mumvura.Iyo yakakosha kudzvanywa ndiyo mhute yekumanikidza kwemvura.Kupenya kunoitika kuzasi kwevharuvhu yekucheka kana dzvinyiriro inodonha pazasi pemhepo yemhute, uyezve mabhuru anodonha kana kudzvanywa kwadzoka pamusoro pemhepo yemhute.Kana mabhubhu adonha, anotumira masaisai anotyisa murukova runoyerera.Kunyanya kunetseka ne cavitation, ndiko kukanganisa kwechidimbu uye muviri wevhavha.Izvi zvinonyanya kukonzerwa nekudonha kwemabhuru.Zvichienderana nehukuru hwe cavitation yakagadzirwa, mhedzisiro yayo inogona kubva kune a
ruzha rwakapfava rwekuridza mhere ine kukuvara kudiki kana kusavapo kwekuisa kune ruzha kukonzeresa kukuvadzwa kwakanyanya kwevharuvhu nepombi yepasi pemvura Severe cavitation ine ruzha uye inogona kunzwika sekunge matombo ari kuyerera nemuvharuvhu.
Ruzha runogadzirwa harisi kunyanya kunetseka kubva pakuona kwekuchengetedza kwemunhu, sezvo kazhinji kacho kuderera muhuwandu uye kusimba uye nekudaro haakonzeri dambudziko kune vashandi.
