Nhungamiro yakakosha yekudzivirira cheki kutadza kwevharuvhu

Tikugashirei kuThomas Insights-mazuva ese, tichaburitsa nhau dzichangoburwa uye ongororo kuitira kuti vaverengi vedu varambe vaine ruzivo nezvemaindasitiri maitiro. Nyora pano kuti utumire misoro yezuva zvakananga kubhokisi rako rekunyora. Anenge indasitiri yega yega inoshandisa mapaipi kutakura mvura inotsamira pakushandiswa kwemavharuvhu ekutarisa. Tarisa mavharuvhu-anonziwo cheki mavharuvhu, cheki mavharuvhu, kana cheki mavharuvhu-kubvumira kuyerera mune imwe chete nzira uchidzivirira kuyerera kune zvakapesana kana zvakapesana. Aya mavharuvhu anongovhurika uye anovhara zvichienderana neiyo hydraulic pressure inogadzirwa nekuyerera kwemvura ichiita pamagetsi evhavha. Cheki mavharuvhu anowanzo shandiswa mumitsetse yeutsi, mitsetse ye condensate, mitsetse yemvura, maHVAC masisitimu, uye mapombi emakemikari ekudya, kungodoma mashoma akajairika maapplication. Aya mavharuvhu zvinhu zvakakosha muzviitiko zvakawanda, nekuti reverse kuyerera kunogona kukonzera kukuvadzwa kukuru kune mimwe michina. Nokudaro, zviratidzo zvekutadza kwevhavha yecheki zvinofanira kuonekwa nokukurumidza sezvinobvira kudzivirira nzvimbo yekuderera uye kugadzirisa kunodhura. Kupfeka kwe elastomers uye zvisimbiso zvezvigaro uye kupisa kwakanyanya kwekushanda kunogona kukonzera kukanganisa kwevharuvhu. Kiyi yekudzivirira cheki kutadza kwevhavha uye kuve nechokwadi chehupenyu hwevhavhavha hwakakodzera uye nguva dzose kudzivirira kuchengetedza. Danho rekutanga uye rinoshanda zvakanyanya kudzivirira kutadza kwevharuvhu kuchengeta pombi nemavharuvhu zvakachena uye zvisina tsvina. Izvi zvinogona kuwanikwa nekuisa mafirita nemavhavha panodiwa. Iyo pombi system inogona zvakare kugezwa nguva nenguva kubvisa marara akaiswa uye kuderedza kuunganidzwa kwezvinosvibisa. Valve lubrication ndiyo imwe nzira inoshanda yekudzivirira nguva isati yakwana kutadza kwevharuvhu. Cheki vharuvhu inoumbwa nezvikamu zvakawanda zvinofamba; saka, kuderedza kupesana pakati pezvikamu izvi kuburikidza nekuzora kunogona kuwedzera hupenyu hwebasa rezvikamu zvevharuvhu, kuvandudza kushanda kwese, uye kuve nechokwadi chekushanda kwakanaka. Pakupedzisira, valve inofanira kuiswa nenzira yakarurama uye inoshandiswa sezvakarayirwa. Kuiswa kusina kunaka kwevhavha kana kushandisa rudzi rusina kunaka rwevhavha yekuongorora kunopfupisa hupenyu hwebasa revhavha. Urongwa hwekugadzirisa nguva dzose hunofanirawo kushandiswa kuti huve nechokwadi chokuti mavharuvhu asina kunaka anotsiviwa pazviratidzo zvekutanga zvekukundikana. Paunosarudza saizi yevharuvhu, yeuka kuongorora vheji yekutarisa kune yakapihwa application, kwete ukuru hwepombi. Tichifunga nezveramangwana rekuda simba, kuwedzera saizi yepombi itsika yakajairika. Zvisinei, hombe yepombi dhayamita ichaburitsa yakaderera kuyerera mwero, izvo zvinoreva kuti panogona kunge pasina yakakwana yemvura velocity yekuvhura zvizere cheki valve. Izvi zvinoita kuti vharafu inotenderera, iyo yakakura zvichienderana nedhayamita yepombi, ichitenderera ichidzoka nekudzoka pakati penzvimbo dzakavhurika uye dzakavharika zvishoma. Chiitiko ichi chinonzi chattering. Kuwanda kwekufamba kunokonzerwa nekudengenyeka kunozopedzisira kwawedzera chiyero chekupfeka kwevhavha uye kukonzera kukanganisa kwechikamu, izvo zvichawedzera kukuvadza zvimwe zvigadzirwa zvepasi. Nokudaro, cheki chevhavha inofanira kusarudzwa maererano nehuwandu hwekuyerera hunotarisirwa. Izvi zvinosanganisira kusarudza vharafu ine yakafanira valve coefficient (CV) kukosha. Iyo CV kukosha inotsanangura kugona kwepakati inoyerera kuvhura zvizere valve; iyo yakakwirira yeCV, iyo yakakura kuyerera kunodiwa kuvhura vharuvhu. Iwe unofanirwawo kufunga nezvemhando yepakati ichapfuura nepakati pevhavha. Semuenzaniso, corrosive kana abrasive media inogona kuda kushandiswa kwezvimwe zvinhu zvevharuvhu, senge carbon steel, Stainless steel, kana brass. Uye zvakare, zvinodikanwa kuti titarise maitiro emvura inopfuura nepapombi kuti ive nechokwadi chekuyerera kusingapindike. Solids, zvinwiwa, uye magasi ese akasiyana muviscosity, density, uye mhando. Iyo yemukati mavharuvhu meshini inofanirwa kubvumira iyi yakasarudzika midhiya kuti igarwe. Kutariswa kwevharuvhu kwakakoshawo kuti uone mhando chaiyo yevharuvhu yekutarisa kune yakapihwa application. Kana yaiswa pasi pemamiriro ekuyerera, mamwe mavharuvhu anogona kusashanda sezvaitarisirwa. Pamusoro pezvo, kana vharafu ichionekwa seyakakodzera kuyerera kwakamira, gwara (kumusoro kana pasi) rinofanira kutariswa nekuti aya mamiriro ane zvakasiyana zvinodiwa. Kunyange zvazvo mavhavhavha ose ekuongorora anoita basa rimwe chete, maitiro avo emukati anobvumira nzira imwe chete inoyerera nenzira dzakasiyana. Imwe neimwe yemaitiro aya inokodzera mamiriro akasiyana; saka, zvinodikanwa kuti unzwisise nzira dzekushandisa dzemavharuvhu aya kuti uone kuti ndechipi chikumbiro chaanonyanya kukodzera. Mhando dzakasiyana dzemavharuvhu echeki-kunyangwe iwo akafanana nemafungiro-akasiyana zvakanyanya maererano nemukati wevharuvhu mashandiro, kuputika kumanikidza (kwakabatana neCV), uye zvinhu zvekuvaka. Zvishandiso zvemukati zvemavharuvhu aya zvinonzwawo kumarara, kuyerera kwemazinga uye kukwirira kwepamusoro. Nokudaro, kusarudzwa kwakakodzera kwevharuvhu uye kuongorora kwakakodzera kwemaitiro ndiyo kiyi yekudzivirira kutadza kusati kwasvika kwekuvhara mavharuvhu mune chero rudzi rwekushandisa.
