    1. Nzwisisa S355 JR spiral simbi pombi:

    S355 JR spiral simbi pombiinogadzirwa neyepamusoro-giredhi S355JR simbi uye iri spiral seam pombi yakanyatsogadzirirwa gasi pombi yekuvaka mafomu.Iyo spiral seam chimiro chinopa iyo pombi simba rakanakisa uye kuchinjika, zvichiita kuti ive yakanakira kufambisa kure uye kutakura gasi rechisikigo.Kusimba kwayo kunovimbisa kuramba kune zvekunze zvinhu zvakadai sekufamba kwepasi, seismic chiitiko uye kuora kwevhu, nekudaro kuve nechokwadi chekugara kwenguva refu uye kuvimbika kwegasi rechisikigo pombi system.

    2. Chengetedzo kutanga:

    Kuvimbika uye kuchengetedzeka kwemapaipi egasi echisikigo kwakakosha kune kugara zvakanaka kwenharaunda uye nharaunda.Kusimba kwepamusoro uye kusimba kweS355 JR spiral simbi pombi inoita basa rakakosha mukudzikisa njodzi yekuvuza, kuputsika uye tsaona dzinotevera.Nekuda kwekuvaka kwayo seam seam, chimiro chepombi chinoramba chakasimba kunyangwe munzvimbo dzakaoma kana mamiriro ekunze akanyanya.Kubatanidza pombi iyi mupombi yepombi yegasi chaiyo kunoderedza zvakanyanya mukana wenjodzi kwezvakatipoteredza uye kunobvumira kuyerera kusingapindiki kwegasi rechisikigo kugumisa vashandisi.

    3. Kugara kwenguva refu kwezvivakwa:

    Kusimba kwepamusoro kweS355 JR spiral simbi pombi inovimbisa hupenyu hurefu hwepombi yako yegasi zvivakwa, kuchengetedza kuchengetedza uye kutsiva mutengo nekufamba kwenguva.Iyo pombi inogadzirwa neyepamusoro-giredhi S355JR simbi, iyo ine yakanakisa corrosion resistance, kukanganisa kupikisa uye kupfeka kuramba.Kupokana uku kunoderedza kugadzirisa uye kutsiva, nekudaro kudzikisa huwandu hwemamiriro ekunze uye kuburitsa kabhoni kwakabatana nekugadzirisa pombi uye kuvakazve.Iyo yakawedzera hupenyu kutenderera kweS355 JR spiral simbi pombi inobatsira zvakananga kune yakagadzikana uye ine hushamwari gasi pombi system.

    4. Vandudza kufamba zvakanaka:

    Kubudirira mukufambisa gasi rechisikigo kunosanganisira kuderedza kurasikirwa kwesimba uye kuwedzera kutapurirana.Iyo spiral seam chimiro cheS355 JR spiral simbi pombi inobvumira kutsetseka, kunogara kuyerera kwemhepo, kuderedza kurasikirwa kwekupokana uku uchiwedzera pombi yekufambisa.Iyo pombi ine yunifomu yemukati yepamusoro inoita kuti optimized flow dynamics, nokudaro kuderedza kushandiswa kwesimba uye kuwedzera kushanda zvakanaka.Pamusoro pezvo, huremu hwepombi hunoita kuti kubata, kufambisa uye kuisa kugoneke, kuchengetedza nguva uye mutengo panguva yekuvaka.

    Mhedziso:

    Kubatanidza S355 JR spiral simbi pombi mukugadzirwa kwepombi yegasi kwakaratidza kuvandudza kushanda kwezvivakwa.Iyo pombi ine simba rinoshamisa, kusimba uye kuchengetedza zvinhu zvinofambisa kufamba zvisina musono kwegasi rechisikigo, kuderedza njodzi yetsaona, njodzi kwezvakatipoteredza uye mari yekugadzirisa.Nekunatsiridza kunyatsoita zvekufambisa uye kuderedza kurasikirwa kwesimba, pombi inoita basa rakakosha mukuzadzisa kudiwa kwesimba kuri kukura uku uchimbundikira maitiro akasimba.Kudyara mukugadzirisa zvigadziriso zvakaita seS355 JR spiral simbi pombi kwakakosha kuhurumende, maindasitiri nenharaunda kuti ive nechokwadi chekupihwa kwesimba rakavimbika, rinoshanda uye kugadzira nzira yeramangwana rakachena resimba.
