Izici ze-Ductile Iron Manhole Cover

1. Ukuqina okuhle:Inani lomthelela wensimbi yekhabhoni ephakathi lihle kakhulu, liphindwe izikhathi ezingaphezu kweziyishumi kunensimbi empunga ephonswe.

2. Ukumelana nokugqwala okunamandla: Esivivinyweni sokugqwala sokufafazwa ngamanzi, inani lokugqwala ezinsukwini ezingama-90 liyi-1/40 kuphela yamapayipi ensimbi kanye ne-1/10 yamapayipi ensimbi ampunga. Isikhathi senkonzo siphindwe kabili kunesamapayiphi ensimbi ampunga kanye nezikhathi ezinhlanu kunesamapayiphi ensimbi ajwayelekile.

3. Ukuqina okuhle: Ukwelulwa ≥ 7/100, okufana nensimbi enekhabhoni ephezulu, kuyilapho ukwelulwa kwezinto zensimbi ezimpunga kungu-zero.

4. Ukuqina okuphezulu: Amandla okudonsa ó b angu-≥ 420MPa, kanti amandla okukhiqiza angu-≥ 300MPa, okufana nensimbi ephansi yekhabhoni futhi okuphindwe kathathu kunensimbi empunga ephonswe ngensimbi.
Amandla insimbi ethambile ilingana neyensimbi ephothiwe. Insimbi ephothiwe inamandla okukhiqiza aphezulu okungenani angu-40k, kuyilapho insimbi ephothiwe inamandla okukhiqiza angu-36k kuphela. Eziningi zezicelo zikamasipala, njengamanzi, amanzi anosawoti, umusi, njll., ukumelana nokugqwala kanye nokumelana nokushiswa kwensimbi ephothiwe kudlula okwensimbi ephothiwe. Izindawo eziyinhloko zokusetshenziswa yilezi: imigwaqo kamasipala, imigwaqo emikhulu, ukuxhumana, ugesi, ukugcinwa kwamanzi, imiphakathi, izikole, kanye namapaki ahlukahlukene.

5. Ukusebenza okungcono kokulwa nokweba kanye nokuphepha:
Amandla okudonseka kanye nokumelana nengcindezi kwama-tweezers embobo yensimbi ethambile kufana nensimbi, ngakho-ke abizwa ngokuthi insimbi ehlanganisiwe. Uma kuqhathaniswa nensimbi ehlanganisiwe yendabuko empunga, izinga layo lokunwebeka lithuthuke kakhulu, ukuqina kwayo kuhle, futhi ayiphuki kalula. Isebenza kangcono ekulweni nokwebiwa kunokuvamile. izembozo zomgodi wensimbi ephonswe, futhi ukusebenza kwayo iyonke kuphakeme kakhulu kunokuvamile Umngxuma Wensimbi Ophonswe Ngensimbi izembozo.
