Patinofunga nezvezviteshi zvemagetsi zvinoshandisa mvura, tinowanzo fungidzira madhamu makuru, maturbine ane simba, uye majenareta achirira nesimba. Zvisinei, kune murindi akanyarara, akamira ari pamberi pebasa iri, achishanda asinganeti kudzivirira sisitimu yese: Trash Rack.
Chii chinonzi Rack yeMarara?
Raki yemarara ichidzitiro chakasimba kana chipingamupinyi, chinowanzo gadzirwa nesimbi, chakaiswa panzvimbo inopinzwa mvura nemagetsi emvura. Basa rayo guru nderekuti mvura isati yapinda mu penstock (mugero mukuru unoenda kuma turbines), uye inongori nyore sezita rayo: kuunganidza marara.
"Marara" aya haasi marara chete; anosanganisira marudzi ese emarara anoyangarara uye akadzika mumvura anotakurwa nerwizi, kusanganisira: Matanda nemapazi, Mashizha nemasora emumvura,Marara epurasitiki nemamwe marara akagadzirwa nevanhu,Matombo echando munguva yechando
Sei Zvichikosha Kwazvo?
Nzvimbo yekuchengetera marara haisi yekungosefa chete; chinhu chakakosha pakuchengetedza, kushanda zvakanaka, uye kugara kwenguva refu kwenzvimbo yemagetsi inogadzirwa nemvura.
Kudzivirira Mabanga eTurbine: Iri ndiro basa rayo guru. Marara anopfuura nemumarara anogona kukonzera kukuvara kukuru kumabanga eturbine anomhanya zvikuru, akagadzirwa nemazvo. Kunyangwe chidimbu chidiki chehuni kana purasitiki chinogona kukonzera kusawirirana, kutsemuka, kana kutadza kushanda zvachose, zvichikonzera kugadziriswa kunodhura uye nguva yakareba yekushanda.
Kuona Kushanda Nesimba: Turbine yakavharika kana yakakuvara haigone kushanda zvakanaka. Nekudzivirira marara kuti asapinde, rack yemarara inobatsira kuchengetedza kuyerera kwemvura nekumanikidzwa kwakakodzera, zvichiita kuti magetsi awane simba rakawanda.
Kudzivirira Kuvharika: Zvinhu zvikuru zvinogona kuvharira mavane akamanikana ekutungamira nezvimwe zvikamu zviri mukati meturbine nepenstock, zvichiita kuti unit ivharwe zvachose. Nzvimbo yemarara inoshanda senzira yekutanga yekudzivirira kubva pakuvharika kwakadaro.
Kuderedza Mari Yekugadzirisa: Nekubata marara nekukurumidza, nzvimbo dzekuchengetera marara dzinoderedza zvakanyanya kusakara kwemidziyo iri pasi pemvura, zvichideredza kuwanda kwemitengo yekugadzirisa michina yakaoma uye inodhura.
Dambudziko: Kuunganidza uye Kugadzirisa
Basa rekuisa marara rinopa dambudziko rayo: marara akaunganidzwa anogona kupedzisira avhara rack pachayo. Isa marara akavharika zvakanyanya inodzivirira kufamba kwemvura, zvichiita kuti pave nekusiyana kukuru kwekumanikidzwa kwemvura pachidzitiro. "Kurasikirwa nemusoro" uku kunoreva kurasikirwa nekugadzira simba.
Apa ndipo panoshanda mumwe wayo anoshanda, iyo Trash Rake. Rake yemarara imotokari yakasarudzika (inowanzo teverwa kana kuti iri muchikepe) ine mbambo inoshandiswa kuchenesa raki yemarara nguva nenguva, ichibvisa marara akaunganidzwa mumvura kuti araswe.
Dhizaini uye Unyanzvi
Matura emarara haakwani zvachose. Magadzirirwo awo anosiyana zvichienderana nenzvimbo yechirimwa uye rudzi rwemarara anowanikwa.
Kupatsanurana kwemabhawa: Nzvimbo iri pakati pemabhawa inoverengwa nokungwarira kuti ivhare zvinhu zvinokuvadza uku ichideredza kuvharika kwemvura.
Zvinhu: Zvinowanzogadzirwa nesimbi dzisingakanganise ngura dzakadai sesimbi isingatsvi kuti dzigare dzakanyudzwa mumvura nguva dzose.
Otomatiki: Mafekitori emazuva ano ane masisitimu ekubvisa marara otomatiki uye masensa ekutarisa anoona kusiyana kwekumanikidzwa, zvichiratidza kana kuchenesa kuchidikanwa pasina kupindira nemaoko.
Mhedziso
Kunyange zvazvo ringave risina hukuru hweturbine kana chiyero chikuru chedhamu, rack yemarara igamba rinonyanya kukosha munyika yemagetsi emvura. Rinomira semhinduro iri nyore asi yakajeka yedambudziko rakaoma, richivimbisa kuti simba rakachena, rinodzokororwa rinoyerera kubva munzizi dzedu rinoita izvozvo zvakavimbika uye zvinobudirira. Nguva inotevera paunobatsirwa nesimba remagetsi emvura, yeuka rack yemarara isina kuzvikudza—muchengeti akanyarara anochengeta mwenje yakabatidzwa.
