Kusiyana mukushandiswa kweDuctile Iron Manhole Covers D400 neE600

D400 neE600 ductile iron maburi ekufukidza maburi chimwe nechimwe chine zvakanakira nezvakaipira. Kusarudza kuti ndechipi chiri nani kunoenderana nemamiriro ekushandiswa chaiwo uye zvinodiwa.

Chekutanga, maererano nekukwanisa kwekutakura, E600 Chifukidziro cheMugodhi inogona kutsungirira huremu hunosvika matani makumi matanhatu, ukuwoChifukidziro chegomba remvura reD400 ine mutoro wepamusoro wematani makumi mana. Saka, E600 yakakodzera nzvimbo dzine vanhu vakawanda dzakadai senhandare dzendege, nzvimbo dzekutakura zvinhu, nedzimwe nzvimbo dzinoda kutsungirira mitoro inorema.

Chechipiri, kana tichitaura nezvezvinhu zvakagadzirwa, manhole cover eE600 anowanzo shandisa zvinhu zvakasimba, izvo zvinoita kuti zvigadzikane kana zvikaiswa mutoro mukuru. Kusiyana neizvi, kunyange zvazvo D400 Mugodhi weD400 chifukidziro chacho chakasimbawo, simba racho harina kusimba zvakanyanya.

Pakupedzisira, kubva pamaonero ezviitiko zvinoshanda, iyo D400 chifukidziro chegomba remugodhi yakakodzera nzvimbo dzine mutoro uri pakati nepakati dzakadai semigwagwa mikuru yemumaguta nemigwagwa mikuru, nepo E600 yakakodzera nzvimbo dzine mutoro wakanyanya dzakadai senhandare dzendege nezviteshi zvekutakura zvinhu. Saka, kana nzvimbo yacho ine vanhu vakawanda kana ichida kutsungirira mutoro unorema, E600 ingave sarudzo iri nani; Munzvimbo dzine vanhu vashoma kana nzvimbo dzinopfuura mota diki, D400 yakakwana kushandiswa.
