Nzira Yekuedza Yematanho Maviri

Kutevera maitiro aya kunovimbisa bvunzo yakakwana uye yakachengeteka. Kutanga, unosimbisa kuvimbika kwepaipi. Wobva wasimbisa kugona kwevharuvhu kuvhara.

1. Kuedzwa kweKuvimbika kweSisitimu (Mavharuvhu Akavhurika):Chinangwa chikuru pano ndechekuwana mvura inodonha mumigero yese yepombi yawakanama. Vhara magumo epombi yako yapera nevharo. Ita shuwa kuti mavharuvhu ese ebhora ari mumutsetse ari munzvimbo yakavhurika yakazaraIzvi zvinoita kuti mvura izadze sisitimu yese, kusanganisira mavharuvhu, saka zvese zvinoedzwa sechubhu imwe chete inoenderera mberi. Isa sisitimu kusvika pakumanikidzwa kwekuyedza zvishoma nezvishoma uye tarisa majoini ese kuti haana kudonha here. Nzira iyi inoedza kugona kwako pakubatanidza mapaipi.
2. Kuedzwa kweChisimbiso cheVharuvhu (Vharuvhu Dzakavharwa):Mushure mekunge sisitimu yapasa bvunzo yekutanga, unogona kuyedza zvigaro zvevharuvhu. Izvi zvakakosha zvikuru kumavharuvhu ekuparadzanisa ari pamucheto wemutsetse. Kana sisitimu yamanikidzwa, vhara vharuvhu zvishoma nezvishoma. Tarisa kana paine kubuda kwemvura kubva pamudzi wevharuvhu uye tarisa divi rezasi revharuvhu kuti uve nechokwadi chekuti inopa chisimbiso chakazara, chakasimba semabubble. Izvi zvinoyedza kunaka kwezvisimbiso zvemukati zvevharuvhu (zvigaro zveTPE/EPDM).

Unogona here kuyedza pombi yePVC yekumanikidza?

Uri kutarisa pombi yePVC ichangobva kunamirwa kwenguva refu. Pfungwa yekuizadza nemvura ine simba rinokumanikidza inoita kuti utye. Ko kana majoini akakundikana kana pombi yacho ikaputika?

Ehe, kuyedza kudzvanywa kwepombi yePVC inzira yakajairika uye inodiwa. Unofanira kushandisa mvura (kuyedza kunobva muhydrostatic) uye kugara mukati memiganhu yekudzvanywa, iyo yakavakirwa pachiyero chekudzvanywa kwepombi uye tembiricha.

Iyi ndeimwe nzvimbo iyo kutevedzera mitemo yakatarwa ndiyo kiyi yekuchengetedzeka nekubudirira. Masisitimu emapaipi ePVC akasimba zvikuru, asi haaparadzike. Sisitimu yese—mapaipi, zvigadziko, nemavharuvhu—yakagadzirwa zvine mwero wekumanikidzwa. Kuyedzwa kwekumanikidzwa ndiyo nzira yatinoratidza nayo kuti kuiswa kwacho kwakaitwa nemazvo uye sisitimu yakagadzirira kushandiswa. Mutemo unonyanya kukosha ndewokuti usamboshandisa mhepo yakamanikidzwa.

Kuedzwa kweHydrostatic vs. Pneumatic

Kushandisa mvura (hydrostatic) ndiyo nzira chete inotenderwa yekuyedzwa kwekumanikidzwamasisitimu emapaipi ethermoplastic. Kushandisa mhepo (pneumatic) kune njodzi huru uye kunorambidzwa nemitemo mikuru.

Usamboshandisa nzira iyi.Ingozi huru yekuchengetedza uye inogona kukonzera kukuvara kwakanyanya kana rufu.

Gara uchitevera "Mutemo we1.5x": kumanikidzwa kwakanyanya kwekuyedzwa hakufanirwe kudarika 1.5 kakapetwachikamu chakayerwa pasimuhurongwa kwenguva pfupi.

Vharuvhu yebhora yePVC inogona kubata kumanikidzwa kwakadii?

Uri kutsvaga mavharuvhu epurojekiti. Unoona makodhi akasiyana akadai sePN10, PN16, kana Schedule 80. Unofanira kuziva kuti ndeipi inogona kubata kumanikidzwa kwesystem pasina njodzi yekukundikana.

Kuyera kwekumanikidzwa kwevharuvhu yebhora rePVC kunoenderana nekugadzirwa kwayo, saizi, uye tembiricha. Vharuvhu yePN10 yakajairika inoongororwa yemabharu gumi (145 psi) patembiricha yemumba, nepo PN16 ichigona kubata mabharu gumi nematanhatu (232 psi).

Iyi ndeimwe yemitemo inonyanya kukosha yandinokurukura naBudi. Kuenzanisa kumanikidzwa kwevharuvhu nezvinodiwa zvesisitimu kwakakosha. Kumanikidzwa, kunowanzonzi CWP (Cold Working Pressure), kwakanyorwa zvakajeka pamuviri wevharuvhu. Inokuudza kumanikidzwa kwakanyanya kunogona kuitwa nevharuvhu musystem yemvura ine tembiricha yakaderera (inenge 20°C / 68°F).

Basa Rinokosha reTembiricha

Pa PVC, kumanikidzwa nekupisa zvakabatana zvakananga. Sezvo tembiricha yemvura iri mupombi ichikwira, simba rechinhu chePVC rinodzikira. Izvi zvinoreva kuti vharuvhu inogona kubata kumanikidzwa kushoma. Izvi zvinonzi "kudzikisa tembiricha."

Kupisa Kwemvura	Chinhu Chinokonzera Kukanganiswa kweDhivhiri	Muenzaniso: Vharuvhu yePN16 (16 Bar)
