isicelo

Kwisiza sokwakhiwa kweprojekthi yobunjineli yombhobho wokuhambisa amanzi,Umbhobho otyatyiweyo wodonga lwe-HDPE kabinikwayeUmbhobho ojijayo wodonga lwe-HDPEzizo zonke iindidi ezimbini zemibhobho yokuhambisa amanzi ehlala ikhethwa ngumntu wonke.

1. Iinkqubo ezahlukeneyo zemveliso

Umbhobho otyatyiweyo wodonga lweHDPE wamkela iteknoloji yokwenziwa kwe-extrusion.Izixhobo zoomatshini zikhupha iimbumba ezimbini zetyhubhu ezixutyiweyo zodonga lwangaphandle kunye nomngxuma ogudileyo wangaphakathi ngaxeshanye, ezidityanisiweyo kwaye zikhutshwe ngexesha elinye.Inkqubo yokuvelisa i-HDPE umngxuma ovuthuzayo wodonga lombhobho kukuvelisa i-polyethylene ephezulu (HDPE) kwixande. tube embryo, kwaye emva koko coil kunye weld.

2. Iimpawu ezahlukeneyo

Ngenxa yokuba inkqubo yemveliso HDPE Double eludongeni amalahle umbhobho yinkqubo extrusion processing, kunye fa izixhobo mechanical kufuneka ifane nobungakanani ububanzi umbhobho.Ngoko ke, ukuba ufuna ukuvelisa i-HDPE yodonga oluphindwe kabini umbhobho otyatyiweyo kunye nobubanzi obukhulu, kufuneka usebenzise izixhobo zoomatshini kunye nefa elikhulu, kunye nexabiso lemveliso ye-R & D yolu hlobo lwezixhobo zoomatshini phantse phezulu.Kweli nqanaba, kuphela i-DN1200 inokuveliswa kwaye yenziwe eTshayina.Ukuhamba kwenkqubo yemveliso ye-HDPE yombhobho ovuthuzayo wodonga olugobileyo aluyi kuthintelwa yidayamitha yombhobho.Ukuqulunqwa kwayo kunye nenkqubo yokucubungula kunokuvelisa imibhobho yobubanzi obukhulu ukuya kwi-DN3000, okunzima ukugqitywa ngezinye iinkqubo zokuvelisa.

3. Iindlela zojongano ezahlukeneyo

I-HDPE Double bellows eludongeni ithatha ikakhulu uqhagamshelo lwesokethi, enokuthi itywinwe ngomsesane wokutywina werabha.Olu hlobo lwemowudi yojongano kulula ukuyifaka kwaye iindleko zokufakela ziphantsi.Umbhobho ovuthuzayo weHDPE wamkela uqhagamshelo lwebhanti enyibilikayo eshushu, kwaye ujongano kufuneka lufudunyezwe kwaye ludityaniswe.Le ndlela yojongano inzima kakhulu, kwaye ixabiso loqhagamshelo liphezulu kancinane kunelo lemivumbo ephindwe kabini.

4. Iindleko zemveliso zihluke kwixabiso

Ngenxa yokuba inkqubo yokuvelisa i-HDPE yodonga oluphindwe kabini lombhobho onamacangci kunye nombhobho ovuthuzayo wodonga lwe-HDPE yahlukile, izinga lokusetyenziswa kwemathiriyeli ekrwada nalo lahlukile.Ukuveliswa kwemibhobho enobubanzi obufanayo bombhobho kunye nokuqina kwendandatho, izinga lokusetyenziswa kwezinto eziluhlaza kwinkqubo yokukhupha iphezulu.Ngamanye amagama, umbhobho ovuthuzayo wodonga lwe-HDPE usebenzisa izinto ezininzi, kwaye ixabiso lemveliso liphezulu, ngoko ke ixabiso liphezulu.

Umchiza weJunhai ukhethekileyo ekuboneleleni nge-HDPE, i-PVC yokukhutshwa kombhobho, udonga oluphindwe kabini lwe-extrusion yombhobho otyatyiweyo, kunye nodonga olungenamgobho lombhobho extrusion, wamkelekile umbuzo.
