Chii chinonzi tambo yepombi ye presure? #hdpe water supply pombi

A. Tsanangudzo

Mapaipi ekumanikidza zvinoreva mvura yemukati ine kumanikidzwa kwakati kwehurongwa hwemapaipi, dhizaini uye kuiswa kunofanirwa kufunga nezve kugona kwekutakura kwemhepo yemukati yemapaipi. Zvinoenderana ne "Code for Construction and Acceptance of Water Supply and Drainage Pipeline Engineering" GB 50268-2018, mapaipi ekumanikidza anoreva mapaipi ekugovera mvura nedhiraivha ane kumanikidzwa kushanda kwakakura kupfuura kana kwakaenzana ne0.1MPa.

B. Hunhu

Inoshandiswa kutakura mvura ine kumanikidzwa nesimba rakawanda uye kusimba kuti ikwanise kumira kumanikidzwa kwemukati.

C. Zvinhu

Shandisa pombi yesimbi, pombi yesimbi isina ngura, pombi yemhangura, PE, PVC nezvimwe zvinhu.

D. Kushandisa

Inoshandiswa zvakanyanya mumigwagwa yemumaguta, kutakurwa kwegasi rechisikigo, kutakurwa kwemvura mumaindasitiri (senge petroleum, indasitiri yemakemikari) uye zvimwe zvinoda kutakurwa nemhepo ine simba rakawanda. #MPPPpipeextrusion

Chii chinonzi tambo yepombi ye "none presure"? #jwell

A. Tsanangudzo

Mapaipi asina kumanikidzwa anowanzo shandiswa kutakura mvura, senge mvura yemvura, tsvina, nezvimwewo negiravhiti kana kuyerera kwechisikigo, pasina kumanikidzwa kwemukati kana kumanikidzwa kushoma kwemvura. Sekureva kweGB 50268-2018, "Code for Construction and Acceptance of Water Supply and Drainage Pipeline Engineering", mapaipi asina kumanikidzwa anoreva mapaipi emvura uye ekudhonza mvura ane kumanikidzwa kushanda kusingasviki 0.1MPa.

B. Hunhu

Kuvimba negiravhiti kuti mvura ifambe zvakanaka, iyo inowanzoshandiswa mukubvisa mvura uye masisitimu etsvina, haigone kumira kumanikidzwa kwemukati.

C. Zvinhu

Mapaipi asina kumanikidzwa ane zvinodiwa zvekudzivirira kumanikidzwa kwakaderera pazvinhu, saka PVC, HDPE, kongiri nezvimwe zvinhu zvinoshandiswa.

D. Kushandisa

Inonyanya kushandiswa mumasisitimu emvura yemumaguta (akadai setsvina nemvura inobuda), mapaipi ekuvaka, kudiridza kwekurima, nezvimwewo. Semuenzaniso, mapaipi emvura eUPVC anoshandiswa mudzimba dzekugezera, mapaipi emvura yemvura anowanikwa padenga, mapaipi emvura akavharirwa edzimba dzekugara, ma air conditioner, mapaipi emvura yetsvina yemvura uye mvura yemvura haisi yepressure. #mapaipi emvura

Chii chinonzi pombi inochinjika?

A. Tsanangudzo

Pombi inochinjika inoreva pombi inogona kugadzira shanduko yakati pasi pesimba rekunze, uye kugona kwayo kunoenderana nerutsigiro rwevhu rakatenderedza. Mushure mekuchinjika, mutoro unogona kupararira kuburikidza nekubatana pakati pevhu rakatenderedza nepombi. #pipewinder
Sekureva kweGB 50268-2018, mapaipi anochinjika imapaipi ane deformation yakakura pasi pemutoro wekunze, uye mutoro wakawanda we vertical unoenzaniswa ne elastic resistance inogadzirwa nevhu kumativi ese epaipi, uye kutadza kwepaipi kunowanzo kukonzerwa ne deformation, pane kukuvara kwemadziro epaipi. Kunyanya, zvinoreva mapaipi esimbi, mapaipi emakemikari ekuvaka uye mapaipi esimbi ane flexible interfaces.

B. Hunhu

Kuti ikwanise kumira zvakanaka pasi uye mitoro yekunze, haizokuvadzwi nekukanganisika kudiki.

C. Zvinhu

Mapaipi anochinjika anowanzogadzirwa neHDPE (high-density polyethylene), PVC (polyvinyl chloride), PP (polypropylene) nezvimwe zvinhu zvepurasitiki, zvinogona kuva nekugona kudzoreredza kwakasimba kana zvaoma.

D. Kushandisa

Inoshandiswa zvakanyanya kana paine hwaro hwepasi pevhu, kudengenyeka kudiki kwepasi uye kumanikidzwa kwekufamba kwemotokari, zvakaita semadhairekitori emvura ari pasi pevhu mumaguta, kudiridza kwekurima, mapaipi egesi nezvimwewo.
