Ndi kukula kobowola kotani komwe kumafunikira ma bolt a Chemical a M20?
Maboti a M20 amafunikira dzenje la 25mm.
Kodi bowo liyenera kubowoledwa bwanji kuti likhale ndi nangula wamankhwala wa M20?
Kubowola kwa mankhwala a m20 kumafuna dzenje la 26mm.
Kuzama kwa nangula wa mankhwala a M20
Kuzama kwa mankhwala a nangula bawuti m20 nthawi zambiri kumakhala 12-14mm, yomwe imawerengedwa motengera kuwerengera kwakuya kwa nangula D = (0.6-0.7)d, pomwe D ndi kuya kwa nangula ndipo d ndi m'mimba mwake.
Makhalidwe a M20 ma bolt a nangula amankhwala:
1. Kuyika kosavuta ndi mtengo wotsika;
2. Palibe mphamvu yokulirapo yomwe imapangidwa, mphamvu yotulutsa mphamvu, yonyamula katundu mwachangu, yosagwedezeka, yosagwira kutopa, komanso yosakalamba;
3. Imatengera zinthu zatsopano, asidi ndi alkali zosamva, zotetezeka komanso zachilengedwe;
4. Itha kugwiritsidwa ntchito nthawi zonse pakutentha koyipa;
5. Mabotolo amphamvu kwambiri amapangidwa ndi mankhwala (machubu agalasi) ndi ndodo zachitsulo (zapamwamba kwambiri za carbon structural steel kapena zitsulo zosapanga dzimbiri).
