Inzuzo ye-iron ductile umngxuma wokugubungela i-grate

• I-Ductile umngxuma wentsimbi yokugubungela i-grate yokugubungela
  

Yenziwe ngentsimbi ethe tyaba kunye nentsimbi ephothiweyo yesikwere okanye intsimbi edityanisiweyo necwecwe.

Nazi ezinye zeempawu zabo

I-1, inkangeleko entle, umsele, amandla aphezulu, iinkcukacha kunye neendleko eziphantsi.

2. Anti-ubusela.

3. Umthamo ofanelekileyo wokuthwala.

4.Umthamo oqinileyo wokukhupha amanzi.

Amanqaku amabini okuqwalaselwa ekufakeni i-ductile iron inhole cover grate:

① : Ukuze kuqinisekiswe iimfuno zamandla ezisisiseko, ngaphambi kokufaka i-grate yemvula, isiseko sesamente kufuneka sibekwe.Emva koko faka i-grate yemvula kuyo.

② : emva kokufakwa kwe-grate yemvula, i-screws yokuqinisa kufuneka ifakwe ngeenxa zonke, kwaye udaka lwe-samente kufuneka lugalelwe phantsi kwesakhelo ukukhusela i-grate yemvula ukuba ingawi ngenxa yezizathu ezahlukeneyo.
