Nei Iwe Uchida Mhepo Yemhepo / Vacuum Relief mune Yako yekudiridzira sisitimu

 

Hatiwanzofunga nezvemhepo patinenge tichironga nzira yekudiridza, zvisinei, chimwe chinhu chinofanira kuva nehanya nazvo.Zvinhu zvitatu zvinonyanya kunetsa ndezvi:

  1. Kana mapaipi ako asina kuzara nemvura, azere nemhepo.Mhepo iyi inofanirwa kudzingwa sezvo mvura ichizadza mitsetse.
  2. Panguva yekushanda kwemaitiro ako ekudiridza, mhepo yakanyunguduka inosunungurwa kubva mumvura nenzira yemabhuru.
  3. Pakuvharwa kwehurongwa, vacuum mamiriro anogona kusimuka sezvo mvura ichibuda kunze kwepombi kana mweya wakakwana ukasaunzwa mumitsetse.

Chero ipi yeiyi nyaya inogona kugadziriswa nekuiswa kwakaringana kwemhepo inobuda uye vacuum yekuyamura mavharuvhu.Izvi zvinogona kudzivirira kukanganisa kune zvakakosha zvikamu muhurongwa hwako hwekudiridza.

Tichaita zvatinokwanisa kutsanangura nyaya dzine chokuita nemhepo uye vacuum mupombi yekudiridza;marudzi akasiyana-siyana evhavha: Automatic (Inoenderera) Mhepo Inosunungura Mavhavha, Mhepo / Vacuum Relief Valves uye Combination Air / Vacuum Relief uye Air Release Valves;uye kuiswa kwakakodzera kwemavharuvhu okuyamura aya.

 

Mhepo Yakavharirwa muPipeline Yakamanikidzwa

 

Mhepo inopinda sei mumapaipi?

Mumadiridziro mazhinji, mapaipi akazara nemhepo kana sisitimu isiri kushandiswa.Kana madiridziro ako akavhara mvura zhinji inoyerera kunze kuburikidza nemaemitter kana chero mavharuvhu ekudhonza emotokari aungave wakaisa uye anotsiviwa nemhepo.Uyezve, mapombi anogona kuunza mweya muhurongwa.Pakupedzisira, mvura pachayo ine mhepo inenge 2% nehuwandu.Mhepo yakanyungudika inobuda nekudziya kana kudzvanywa shanduko muhurongwa nenzira yemabhuru madiki.Mhepo uye kumhanya kwemvura kunowedzera mhepo yakanyungudika.

 

 

Mhepo yakabatwa inokanganisa sei sisitimu?

Mvura inogona kuita ka800 kudhanha kupfuura mweya, saka mweya wakavharirwa unodzvanywa kana system yazara, inoungana panzvimbo dzakakwirira uye kuita homwe dzemhepo dzinogona kukanganisa.Kana kuunganidzwa kwemhepo kukangoerekana kwabviswa kunogona kukonzera kuvhuvhuta kwemvura, kunonzi sando yemvura, iyo ine mhedzisiro inokuvadza pamapombi, mafittings uye zvikamu.Kufa musoro kwepombi nderimwe dambudziko.Izvi zvinoitika kana kuyerera kwemvura kwakamiswa uye pombi impeller inoramba ichitenderera ichikonzera kuti tembiricha yemvura ikwire kusvika pamwero unogona kukuvadza pombi.Corrosion kubva cavitation zvakare kunetseka.Cavitation ndiko kuumbwa kwemabubbles kana voids mumvura iyo painorovera inogona kukonzera mafungu madiki ekuvhundutsa ayo anogona kukuvadza madziro epombi uye zvikamu.Mhepo yakavharirwa inonyanya kuwanda mumasisitimu akadzika kwazvo kana munzvimbo refu dzepombi apo homwe dzemhepo dzinogona kudzora kana kumisa kuyerera kana isina kuburitswa.

 

Ndedzipi mhinduro dzekudzivirira mweya wakavharirwa?

Chekutanga uye chakakosha kuisa mhepo yekuyamura kana kuburitsa mavharuvhu panzvimbo dzakatarwa muhurongwa hwako.Aya anogona kunge ari otomatiki yekuyamura mavharuvhu kana kunyange mahydrants kana mavharuvhu anoshanda nemaoko.Tevere, dzikisa mapoinzi epamusoro kana mapikisi muhurongwa hwako zvakanyanya sezvinobvira.Ramba uchifunga kuti kumhanya kwemvura kunosundidzira mabhuru emhepo kusvika kunzvimbo dzakakwirira saka ronga system yako zvakafanira kunyanya mudhizaini yakaderera.Kana ukashandisa pombi, chengetedza kusveta zviri pasi pemvura kudzivirira kupuruzira mweya nemvura.

 

Vacuum Conditions

 

Chii chinonzi vacuum condition?

Vacuum inotsanangurwa senzvimbo isina chinhu zvachose.Chimiro chevacuum chinoitika kana iwe uchibvisa chinhu kubva munzvimbo yakapoteredza uye pasina chekuchitsiva mukati menzvimbo.Saka kana mvura ichibuda mupombi uye mhepo isingagoni kudhonzwa mukati, pamwero wakafanana, kuti uitsive, ipapo mamiriro evacuum anoitika anogona kuita kuti mapaipi apunzike.

 

Nzira yekudzivirira sei vacuum mamiriro.

Kuisa vacuum yekubatsira mavharuvhu munzvimbo dzakananga mukati mekudiridza kwako.Mumamiriro ezvinhu aya, huwandu hwehuwandu hwemhepo huchatsiva zvakaenzana huwandu hwemvura yakabviswa kubva pamapombi.Vacuum yekuzorora inodzivirirawo kusvetwa kwetsvina nemarara mukati kuburikidza nemaemitter, nekudaro kuderedza kuvharika kwemaemitter ako.

 

Mhepo Mavharuvhu

 

Mhando dzinotevera dzemavharuvhu emhepo zvinhu zvine hydro-mechanical izvo zvinoburitsa mweya mukati kana kubuda mupombi yekudiridza.Ese matatu emavharuvhu aya anowanzo kuvhurika mavharuvhu, anowanzo aine mudziyo wemhando yebhora rinoyangarara rinonamira pakavhurika orifice apo system inodzvanya uye inodonha kana mukati memhepo yasvika kumhepo yemhepo inobvumira mweya kudzokera muhurongwa.

 

Otomatiki (Inoenderera) Mhepo Inoburitsa Valve

Rudzi urwu rwevharuvhu yemhepo ine diki diki rinoramba richiburitsa mhepo shoma mushure mekunge system yadzvanyirira uye yakakura mhepo / vacuum vents yakavharwa.Iyo diki diki saizi haiwanzo kukwana kupinza mweya wakakwana pakudzima kudzivirira kuumbwa kwevacuum.

 

Air Release/Vacuum Relief Valve

Iri rudzi rwevharuvhu rinowanzo kunzi kinetic air valve, hombe orifice air valve, vacuum breaker uye kunyange mhepo yekuyamura vharafu.Izvi zvinoburitsa mavhoriyamu makuru emhepo apo mapaipi anenge achizadza kana kudzvanya pamwe nekubvumidza mweya kudzoka muhurongwa kana mitsetse ichidonha kana kudzikisira.Nekudaro, ivo havagone kuburitsa madiki, asara mahomwe emhepo anoumba achiri kushanda.Mufananidzo uri pazasi unoratidza maitiro eMhepo/Vacuum Valve.

  1. Air venting sezvo system inozadza nemvura.
  2. Sisitimu izere uye yakamanikidzwa, mvura inozadza vharafu uye inovhara iyo vent.
  3. Pakuvhara system, kuderedzwa kudzvanywa kunobvumira kuyerera kudonha uye mweya unodhonzwa musystem inodzivirira vacuum mamiriro.

 

 

Musanganiswa Mhepo / Vacuum Relief uye Air Release Valve

Sezvinoreva zita, vharuvhu iyi, inozivikanwawo sevhavha yehuviri, inoita basa remamwe maviri muchikamu chimwe chete.Kubvumira huwandu hukuru hwemhepo mukati nekubuda pazvinenge zvichidikanwa, pamwe nekuburitsa mhepo shoma nguva dzose panguva yekushanda.Iko kusanganiswa kwemhepo / vacuum valves inogona kushandiswa panzvimbo yeimwe yemamwe marudzi.

Ona kusarudzwa kwedu kweMhepo/Vacuum Relief Mavharuvhu pano.

 

Placement

 

Mavharuvhu emhepo anoshandiswa pamitsetse yemvura uye mitsetse yekutapurirana, yakaiswa panzvimbo dzakakwirira muhurongwa;pa drip line lateral ends;pakuchinja kwegiredhi, senge, pamberi uye mushure memateru;mukumhanya kwakareba kwakachinjika;kazhinji pamberi uye mushure mekuzviparadzanisa kana kuvhara-kuvhara mavharuvhu;uye kudivi rekuyerera kwemapombi etsime rakadzika.Zvakakosha kuti mavhavha emhepo aiswe panzvimbo dzakakwirira nekuti mhepo inosimuka, uye sezvataurwa pamusoro apa, kumhanya kwemvura kunosundira mweya kunzvimbo dzakakwirira.Kuronga kwacho kungaite sekunge kwakaoma, asi kuisa kwakakodzera kwakakosha kune inoshanda nemadiridziro masisitimu.

Kuiswa kwakakodzera kwakakoshawo zvakanyanya.Mavharuvhu anofanirwa kuiswa mune yakatwasuka yakatarisa chete.Kuiswa kwakajairika kuri pamusoro pepombi inosimudza saizi yakafanana neyekupinda kwevharuvhu.Muzviitiko zvakawanda, vharuvhu yekuzviparadzanisa (yakavhara) yakaiswa pazasi kuti igadziriswe nyore.

 

Kukura kwevhavha

 

Kufananidza saizi yevharuvhu kune saizi yepombi ikurudziro yakajairwa yemhepo shoma yekupinza / vacuum yekuzorora.Kumapurazi edu madiki kana evaridzi vedzimba masisitimu ekudiridzisa ane 1” uye pasi pepombi, mavharuvhu emweya edu ½” – 1” anokwana kana anoenderana nekukura kwepombi.Vazhinji vagadziri vanokurudzira 2” uye kumusoro mapaipi madhayamita anoda mashoma maviri” saizi yevharuvhu.

Kune masisitimu makuru kana akaomesesa maverengero ekuona saizi chaiyo, huwandu uye nzvimbo yemavharuvhu ega ega application inogona kuve yakaoma zvakanyanya.Tinokurudzira kubata mugadziri wemadiridziro kune mamwe maapplication ehunyanzvi.
