Sezvamunoona, simbi dzakadai sendarira nesimbi isingatsvi dzine simba rekudhonza rakakwirira kupfuura PVC. Simba iri rinodzibvumira kuchengetedza kumanikidzwa kwakanyanya pasina njodzi yekuputika. Kunyange zvazvo dzichidhura zvakanyanya, idzo sarudzo dzakachengeteka uye dzinodiwa kana kumanikidzwa kwesystem kuchipfuura miganhu yePVC.
Chii chinonzi kumanikidzwa kwemhepo kwakanyanya kwePVC?
Ungangoda kushandisa PVC inodhura zvishoma pakufambisa mhepo yakamanikidzwa. Iyi ipfungwa yakajairika asi ine njodzi zvikuru. Kukundikana pano hakusi kudonhedza mvura; kuputika.
Haufanire kushandisa mavharuvhu ebhora ePVC kana mapaipi akajairwa emhepo yakamanikidzwa kana chero imwe gasi. Kumanikidzwa kwemhepo kwakanyanya kunokurudzirwa izero. Gasi rakamanikidzwa rinochengeta simba guru, uye kana PVC ikakundikana, rinogona kupwanyika kuita zvibodzwa zvakapinza uye zvine njodzi.
Iyi ndiyo yambiro inonyanya kukosha yekuchengetedzwa yandinopa vandinoshanda navo, uye chimwe chinhu chandinosimbisa kuchikwata chaBudi kuti vazvidzidzise. Njodzi yacho haisi kunzwisiswa nemunhu wese. Chikonzero chacho musiyano mukuru pakati pemvura nemafuta. Mvura yakaita semvura haidzvanyiriri. Kana pombi yePVC ine mvura yakatsemuka, kumanikidzwa kwayo kunodonha ipapo ipapo, uye unobuda mvura kana kupatsanurwa. Zvisinei, gasi rinogona kudzvanyirirwa zvakanyanya. Rakafanana nechitubu chakachengetwa. Kana pombi yePVC ine mhepo yakadzvanyirirwa ikakundikana, simba rese rakachengetwa rinoburitswa panguva imwe chete, zvichikonzera kuputika kukuru. Pombi haingotsemuki chete; inopwanyika. Ndakaona mifananidzo yekukuvara kunogona kukonzerwa neizvi, uye injodzi isingafaniri kutorwa nemunhu.
Kukundikana kweHydrostatic vs. Pneumatic Pressure
Njodzi yacho inobva parudzi rwesimba rinochengetwa muhurongwa.
- Kumanikidzwa kwemvura (mvura):Mvura haimanikidzwi nyore nyore. Kana mudziyo une mvura ukatadza kushanda, kumanikidzwa kunobva kwadzikira ipapo ipapo. Mugumisiro wacho unobuda mvura. Simba rinopera nekukurumidza uye zvakachengeteka.
- Kumanikidzwa kwePneumatic (Mhepo/Gasi):Gasi rinodzvinyirirwa, richichengetedza simba rakawanda rinogona kushandiswa. Kana mudziyo ukakundikana, simba iri rinoburitswa zvakanyanya. Kukundikana kwacho kunotyisa, kwete zvishoma nezvishoma. Ndokusaka masangano akaita seOSHA (Occupational Safety and Health Administration) aine mitemo yakasimba inorambidza kushandisa PVC yakajairwa pamhepo yakadzvinyirirwa.
Pakushandisa pneumatic, gara uchishandisa zvinhu zvakagadzirwa uye zvakayerwa magasi akamanikidzwa, akadai semhangura, simbi, kana mapurasitiki akagadzirwa nechinangwa ichocho. Usamboshandisa PVC yemhando yepamusoro.
Chii chinonzi pressure rating yebhora vharuvhu?
Une vharuvhu muruoko rwako, asi unofanira kuziva chiyero chayo chaicho. Kusaverenga kana kusateerera zviratidzo zviri pamuviri wako kunogona kutungamira pakushandisa vharuvhu isina kucherechedzwa zvakanyanya muhurongwa hwakakosha.
Chiyero chekumanikidzwa chinoratidzwa zvakananga mumuviri wevharuvhu yebhora. Kazhinji chinoratidza nhamba inoteverwa ne "PSI" kana "PN," inomiririra kumanikidzwa kwakanyanya kwekushanda kwechando (CWP) patembiricha yekunze, kazhinji 73°F (23°C).
Ndinogara ndichikurudzira vatinodyidzana navo kuti vadzidzise vashandi vavo vekuchengetera zvinhu nevatengesi kuti vaverenge zviratidzo izvi nemazvo. Ndiyo "ID card" yevharuvhu. Kana timu yaBudi ikaburitsa zvinhu, vanogona kuona pakarepo kuti vagamuchiramarongero chaiwo echigadzirwaKana vatengesi vake vachitaura nekontrakita, vanogona kuratidza zviri pavharuvhu kuti vaone kuti inosangana nezvinodiwa neprojekiti. Danho iri riri nyore rinobvisa fungidziro uye rinodzivirira zvikanganiso vharuvhu isati yasvika panzvimbo yebasa. Zviratidzo izvi zvinovimbisa kugona kwevharuvhu kushanda kwayo, uye kuzvinzwisisa kwakakosha pakushandisa chigadzirwa zvakachengeteka uye zvinobudirira. Chinhu chidiki chinoita mutsauko mukuru mukuona kutikudzora mhando mucheni yese yekugovera.
Maitiro Ekuverenga Zviratidzo
Mavharuvhu anoshandisa makodhi akajairwa kutaurirana miganhu yawo. Heano anonyanya kuwanikwa pavharuvhu yebhora rePVC:
| Kumaka | Zvinoreva | Dunhu/Nzvimbo Yakajairika |
|---|---|---|
| PSI | Mapaundi paSquare Inch | Nyika dzakabatana (ASTM standard) |
| PN | Kudzvanywa Kwezita (muBar) | Europe nedzimwe nzvimbo (ISO standard) |
| CWP | Kushanda Kunotonhora Kumanikidzwa | Izwi rinoratidza kumanikidzwa pakupisa kwekunze. |
Semuenzaniso, unogona kuona“150 PSI @ 73°F”Izvi zviri pachena: 150 PSI ndiyo pressure yepamusoro, asi chete pa73°F kana pasi payo. Unogonawo kuona"PN10"Izvi zvinoreva kuti vharuvhu yakayerwa kumanikidzwa kwe10 Bar. Sezvo 1 Bar iri inenge 14.5 PSI, vharuvhu yePN10 yakaenzana nevharuvhu ye145 PSI. Nguva dzose tsvaga nhamba yekumanikidzwa uye chero tembiricha inoenderana nayo kuti uwane mufananidzo wakazara.
Mhedziso
Muganho wekumanikidzwa kwevharuvhu yebhora rePVC unowanzova 150 PSI yemvura, asi chiyero ichi chinoderera nekupisa. Chinonyanya kukosha, usamboshandisa PVC kune masisitimu emhepo yakamanikidzwa.
