Kuiswa kwemavharuvhu egedhi, mavharuvhu eglobe uye mavharuvhu ekutarisa

Vharuvhu yegedhi, inozivikanwawo sevharuvhu regedhi, ivharuvhu inoshandisa gedhi kudzora kuvhurwa nekuvhara. Inogadzirisa kufamba kwepaipi uye inovhura nekuvhara mapaipi nekushandura chikamu chepaipi. Mavharuvhu egedhi anonyanya kushandiswa mumapaipi ane mvura yakavhurika zvizere kana yakavharwa zvizere. Kazhinji hapana chinodiwa chekuisa vharuvhu regedhi, asi haigone kuiswa yakatarisa pasi.

Avharuvhu yepasi roseivharuvhu inoshandisa dhisiki revharuvhu kudzora kuvhurwa nekuvhara. Nekuchinja mukaha uri pakati pedhisiki revharuvhu nechigaro chevharuvhu, kureva kuti, kuchinja saizi yechikamu chemugero, kuyerera kwepakati kana nzira yepakati kunogurwa. Pakuisa vharuvhu yekumisa, kutarisisa kunofanirwa kupihwa kune kwakanangana nekuyerera kwemvura.
Nheyo inofanira kutevedzerwa pakuisa vharuvhu yekumisa ndeyekuti mvura iri mupaipi inopfuura nepaburi revharuvhu kubva pasi kuenda kumusoro, inozivikanwa se "low in and high out", uye kuisa reverse hakubvumirwi.

Vharuvhu yekutarisa, inozivikanwawo se check valve uye one-way valve, ivharuvhu inovhura yoga uye inovhara pasi pemusiyano wekumanikidzwa uri pakati pekumberi nekumashure kwevharuvhu. Basa rayo nderekubvumira medium kuti ifambe nenzira imwe chete uye kudzivirira medium kuti isafambe ichidzokera kune imwe nzira. Zvichienderana nemaumbirwo akasiyana, mavharuvhu e check anosanganisira lift, swing uye butterfly clamp check valves. Mavharuvhu e check lift akakamurwa kuita mhando dzakatwasuka nedzakatwasuka. Pakuisa check valve, unofanirwawo kutarisisa mafambiro e flow ye medium uye usaiise kumashure.

Kuiswa kwevharuvhu yekuderedza kumanikidzwa

Vharuvhu inoderedza kumanikidzwa ivharuvhu inoderedza kumanikidzwa kwekupinda kusvika pakumanikidzwa kunodiwa kuburikidza nekugadzirisa uye inochengetedza yega kumanikidzwa kwakasimba kwekubuda kuburikidza nekushandisa simba rechinhu chacho pachacho.

Kubva pamaonero e fluid mechanics, vharuvhu inoderedza kumanikidzwa chinhu chinodzongonyedza chinogona kuchinja resistance yenzvimbo. Kureva kuti, nekuchinja nzvimbo inodzongonyedza, mwero wekuyerera uye kinetic energy yemvura zvinochinjwa, nokudaro zvichigadzira kurasikirwa kwakasiyana kwekumanikidzwa, nokudaro zvichizadzisa chinangwa chekuderedza kumanikidzwa. Zvadaro, zvichienderana nekugadziriswa kwesystem yekudzora nekutonga, simba rechitubu rinoshandiswa kuyera kushanduka kwekumanikidzwa kuri shure kwevharuvhu, kuitira kuti kumanikidzwa kuri shure kwevharuvhu kurambe kuri mukati meimwe error range.

Kuiswa kwevharuvhu yekuderedza kumanikidzwa

1. Boka remavharuvhu anodzikisa kumanikidzwa rakaiswa rakamira rinowanzoiswa pamadziro pakakwirira zvakakodzera kubva pasi; boka remavharuvhu anodzikisa kumanikidzwa rakaiswa rakatambanuka rinowanzoiswa papuratifomu inoshanda nguva dzose.

2. Shandisa simbi yakaumbwa kuti uise pamadziro kunze kwemavharuvhu maviri ekudzora (anowanzo shandiswa kumavharuvhu ekumisa) kuti ugadzire bhureki. Pombi yepasspass inonamirwawo pabhureki uye yakaenzana.

3. Vharuvhu inoderedza kumanikidzwa inofanira kuiswa yakamira papombi yakatwasuka uye haifanirwe kutsveyamiswa. Museve uri pamuviri wevharuvhu unofanira kunongedzera kwakananga kuyerera kwepakati uye haugone kuiswa kumashure.

4. Mavharuvhu ekumisa uye mageji ekumanikidza akakwira uye akaderera anofanira kuiswa kumativi ese kuti aone kuchinja kwekumanikidza asati avhara uye mushure mevhararuvhu. Dhayamita yepombi mushure mevharuvhu rekuderedza kumanikidzwa inofanira kunge yakakura ne2#-3# kupfuura dhayamita yepombi inopinza iri pamberi pevharuvhu, uye pombi yepasspass inofanira kuiswa kuti iite kuti kugadziriswa kuve nyore.

5. Pombi inoenzanisa kumanikidzwa kwevharuvhu yekuderedza kumanikidzwa kwediaphragm inofanira kubatanidzwa nepaipi ine kumanikidzwa kwakaderera. Mapaipi ane kumanikidzwa kwakaderera anofanira kunge aine mavharuvhu ekuchengetedza kuona kuti system yacho inoshanda zvakachengeteka.

6. Kana ichishandiswa kubvisa mhute, pombi yekudhonza mvura inofanira kuiswa. Kune masisitimu emapaipi ane zvinodiwa zvakanyanya zvekuchenesa, sefa inofanira kuiswa pamberi pevharuvhu inoderedza kumanikidzwa.

7. Mushure mekunge boka revharuvhu rekuderedza kumanikidzwa raiswa, vharuvhu rekuderedza kumanikidzwa nevharuvhu rekuchengetedza zvinofanira kuongororwa kumanikidzwa, kusukurudzwa uye kugadziriswa zvichienderana nezvinodiwa pakugadzira, uye kugadziriswa kwacho kunofanira kuiswa chiratidzo.

8. Paunenge uchisuka vharuvhu rekuderedza kumanikidzwa, vhara vharuvhu rekupinda rinodzikisa kumanikidzwa wobva wavhura vharuvhu rekusuka kuti risuke.

Kuisa misungo

Basa guru remuteyo wemhepo nderekuburitsa mvura yakagayiwa, mhepo negasi recarbon dioxide mumhepo yemhepo nekukurumidza sezvinobvira; panguva imwe chete, inogona kudzivirira kubuda kwemhepo yemhepo zvakanyanya. Kune mhando dzakawanda dzemuteyo, imwe neimwe iine hunyanzvi hwakasiyana.

Zvichienderana netsika dzakasiyana dzekushanda kwemisungo yemhepo, inogona kukamurwa kuita mhando nhatu dzinotevera:

Mechanical: Inoshanda zvichienderana nekuchinja kwehuwandu hwemvura inodziya mumusungo, kusanganisira:

Rudzi rwechiyangarara: Chiyangarara ibhora rakavharwa risina chinhu.

Rudzi rwechinoyangarara chinovhurika kumusoro: Chinoyangarara chakaita sebhare uye chinovhurika kumusoro.

Rudzi rwechinoyangarara chinovhura chichidzika: Chinoyangarara chakaita sebhareni, muromo wacho uchidzika.

Rudzi rwethermostatic: runoshanda zvichienderana nekuchinja kwekushisa kwemvura, kusanganisira:

Shiti yeBimetallic: Chinhu chinonzwa ishiti yeBimetallic.

Rudzi rwekumanikidzwa kwemhepo: Chinhu chinonzwa ibhero kana katuriji, iyo yakazadzwa nemvura inoputika.

Rudzi rweThermodynamic: Inoshanda zvichibva pakuchinja kwehunhu hwethermodynamic hwemvura.

Rudzi rweDisiki: Nekuda kwehuwandu hwakasiyana hwekuyerera kwemvura negasi pasi pekumanikidzwa kwakafanana, kumanikidzwa kwakasiyana-siyana kunogadzirwa kuti vharuvhu yedhisiki ifambe.

Rudzi rwekupumha: Kana kuungana kwekupisa kwakasiyana-siyana kuchipfuura nepakati pemaplate e-throttle orifice ane mativi maviri, kumanikidzwa kwakasiyana kunoumbwa pakati pematanda maviri emaplate e-throttle orifice, zvichiita kuti dhisiki revharuvhu rifambe.

Kuisa misungo

1. Mavharuvhu ekumisa (mavharuvhu ekumisa) anofanira kuiswa pamberi nepashure, uye sefa inofanira kuiswa pakati pemusungo nevharuvhu yekumisa yekumberi kudzivirira tsvina iri mumvura ine mafungu kuti isavhare musungo.

2. Pombi yekuongorora inofanira kuiswa pakati pemusungo nevharuvhu yekumira kumashure kuti ione kana musungo uri kushanda nemazvo. Kana ukabuda utsi hwakawanda paunovhura chubhu yekuongorora, musungo wacho unenge wakuvara uye unoda kugadziriswa.

3. Chinangwa chekugadzira pombi yekufambisa mvura ndeyekuburitsa mvura yakawanda yakasanganiswa panguva yekutanga uye kuderedza huwandu hwemvura inoyerera mumusungo.

4. Kana vharuvhu yekudhonza mvura ichishandiswa kubvisa condensate kubva mumidziyo yekudziyisa, inofanira kuiswa pasi pemidziyo yekudziyisa kuitira kuti pombi yemvura inodhonza mvura idzokere yakatwasuka kuvharuvhu yekudhonza mvura kudzivirira kuungana kwemvura mumidziyo yekudziyisa.

5. Nzvimbo yekuisa inofanira kunge iri pedyo nenzvimbo yekubuditsa mvura. Kana daro racho riri kure zvakanyanya, mhepo kana utsi hunogona kuungana mupombi refu, yakatetepa iri pamberi pemusungo.

6. Kana pombi huru yemhepo yakatambanuka yakareba zvakanyanya, nyaya dzekubuda kwemvura dzinofanira kufungwa nezvadzo.
