Pipe yeSimbi dzeCarbon dzakasungirirwa dzakatenderedzwa dzakatenderedzwa dzeSpiral Yekuputira Mitsetse yeMvura

Pipe yeSimbi dzeKabhoni Dzakasungirirwa neSpiral Yekuputira Mitsetse yeMvura Mufananidzo Unoratidzwa

Tsananguro pfupi:

Munzvimbo yakakura yezvivakwa, kushanda zvakanaka kwemasisitimu emvura nemaindasitiri kunoenderana zvikuru nekusimba uye kushanda zvakanaka kwemapombi. Pakati pemhando dzakasiyana dzemapombi ari kushandiswa, mapaipi esimbi yekabhoni akasungirirwa anotenderera anofanira kutariswa nekuda kwesimba rawo rakakura uye kushanduka-shanduka. Pazasi panotanga tsananguro yekukosha uye mabhenefiti emapombi esimbi yekabhoni akasungirirwa anotenderera anotenderera mupombi yemvura uye kupinza mapaipi esimbi.

1. Nzwisisa pombi yesimbi yekabhoni yakasungirirwa nesimbi yakasungirirwa nesimbi:

Spiral welded kabhoni simbi mutopotainogadzirwa nesimbi uye inosungirirwa kubva musimbi. Maitiro ekugadzira akasiyana anoita kuti mapaipi aya ave akasimba uye agare kwenguva refu, achikwanisa kutsungirira kumanikidzwa kwakanyanya kwemukati nekunze. Kugona kudzivirira ngura nekushanduka kunoitawo kuti ive yakakodzera kushandiswa kwakasiyana-siyana, kusanganisira mapaipi emvura uye welding yemapaipi esimbi.

2. Mapombi emvura:

Munzira dzekugovera mvura, kuendeswa kwemvura yakachena kwakachengeteka uye zvinobudirira kwakakosha. Mapaipi esimbi ecarbon akasungirirwa nesimbi aratidza kuva sarudzo yakavimbika yemapaipi emvura nekuda kwehunhu hwawo hunodzivirira ngura. Pamusoro pemapaipi aya panoderedza kukweshana, zvichiita kuti mvura irambe ichiyerera uye inoderedza kutenderera. Pamusoro pezvo, simba remukati uye kugara kwenguva refu zvinovimbisa dziviriro kubva pakudonha kwemvura, kupwanyika, uye kukuvara kwechimiro, zvichiita kuti mvura irambe ichiwanikwa.

3. Kubatanidza mapaipi esimbi:

Indasitiri yekuwedera inoshandisa mapombi esimbi esimbi akasungirirwa nesimbi yaka ...

4. Mabhenefiti nezvakanaka:

4.1 Mhinduro inoshanda zvishoma nezvishoma: Pombi yesimbi yekabhoni yakasungirirwa nesimbi inopa mhinduro inoshanda zvishoma nezvishoma yekusanganisa mapaipi emvura nesimbi. Kugara kwenguva refu kwayo uye kuramba kwayo ngura kunoita kuti igare kwenguva refu, nokudaro zvichideredza mari yekuitsiva nekugadzirisa.

4.2 Zviri nyore kuisa: Tekinoroji yekubatanidza spiral inoshandiswa mukugadzira inogona kugadzira mapaipi akareba uye anoenderera mberi, zvichideredza kudiwa kwemajoini anowanzo shandiswa. Dhizaini iyi inorerutsa maitiro ekuisa, ichichengetedza nguva nesimba.

4.3 Kushanduka-shanduka: Mapaipi esimbi yekabhoni akasungirirwa nesimbi anowanikwa muhukuru hwakasiyana-siyana uye ukobvu, zvichibvumira kuti agadziriswe kuti aenderane nezvinodiwa zvepurojekiti, achienderana nemarudzi akasiyana-siyana emvura, kumanikidzwa uye tembiricha.

4.4 Kudzivirirwa kwezvakatipoteredza: Simbi yekabhoni chinhu chinogona kushandiswazve chinobatsira mukuchengetedza nharaunda. Mapaipi esimbi yekabhoni akasungirirwa nesimbi anogona kushandiswazve, kuderedza marara uye kudzivirira zviwanikwa zvechisikigo.

Mukupedzisa:

Kugona uye mabhenefiti emapombi esimbi yekabhoni akasungirirwa mupombi yemvura uyekusona mapaipi esimbiHazvigone kurerutswa. Kutamiswa kwakanaka uye kwakavimbika kwemvura nemvura dzemumaindasitiri kunoenderana zvikuru nekugara kwenguva refu kwazvo, kuramba ngura uye nyore kuisa. Sezvo kudiwa kwezvivakwa zvakasimba uye zvisingadhuri kuri kuramba kuchikwira, mapaipi esimbi ecarbon akasungirirwa nesimbi acharamba ari chinhu chakakosha mukuona kuti masisitimu emvura nemaindasitiri anoshanda zvakanaka pasi rese.
