Unyango lomphezulu we-pulley

Iipulley yokuhambisaUmphezulu ungaphathwa ngeendlela ezahlukeneyo ngokweemeko ezithile kunye neemeko ezithile. Iindlela zonyango zahlulwe zibe zezi zilandelayo:

1. Gukuhlaziywa kwe-alvanization

I-Galvanization ifanelekile kwizixhobo zoshishino ezisetyenziswa kushishino olulula, izixhobo, ishishini le-electromechanical, oomatshini bezolimo, ishishini lokhuselo lwesizwe, njl. Njengeyona ndlela ixhaphakileyo yonyango lomphezulu we-pulley okwangoku, inobuhlobo nokusingqongileyo kwaye ineempawu ezilandelayo xa ithelekiswa ne-galvanizing yendabuko:

(1) Musa ukusebenzisa i-cyanide enetyhefu, ukuze amanzi amdaka avelisweyo anyangwe lula.

(2) Ingubo ine-crystallization entle, i-gloss entle, kwaye amandla okusasaza kunye nokukwazi ukugquma okunzulu kufana nqwa nesisombululo sokugquma i-cyanide, esifanelekileyo kwi-electroplating yeenxalenye ezineemilo ezintsonkothileyo.

(3) Isisombululo sokugquma esizinzileyo kunye nokusebenza okulula

(4) Akukho monakalo kwizixhobo

(5) Ixabiso eliphantsi

 

2. Chroipleyiti

I-chromium yokuhombisa isetyenziswa kakhulu kwiimoto, iibhayisekile, izixhobo zasekhaya, izixhobo zasekhaya, izitshintshi zezixhobo, iindawo zoomatshini kunye nezinye izixhobo kunye nezibonelelo. Ukuhombisa i-chromium kusetyenziswa itekhnoloji ye-nickel, i-nickel chromium ukuqinisekisa umgangatho wemveliso. Umphezulu umhlophe wesilivere, uhonjiswe nge-chrome enokumelana nokugqwala okunamandla kunye nesiphumo esihle sokuhombisa, kunye ne-coefficient ephezulu yokubonakalisa.

3. Isigqubuthelo serabha

Umbhobho wentsimbi yesinyithi ugqunywe ngerabha, uze uvunguzwe ukuze wenze i-pulley yesigqubuthelo serabha. Xa kuthelekiswa ne-pulley eqhelekileyo, i-pulley yesigqubuthelo serabha ineempawu zokuba yi-elastic, ukumelana nokuguguleka, ukumelana ne-asidi kunye ne-alkali, ukumelana neoyile (NBR), ukumelana nobushushu kunye nokumelana nomhlwa njl.njl. Kusetyenziswa izinto ezikrwada kunye nezincamathelisi ezivela kwamanye amazwe. Irabha yendalo kunye ne-NBR zihlala zisetyenziswa. Imibala ecetyiswayo imnyama, eluhlaza kunye nongwevu olukhanyayo.

4. I-chrome plating eqinileyo

I-chromium eqinileyo ikwaziwa ngokuba yi-chromium engagugiyo, unyango lunokunyusa ubulukhuni bomphezulu we-pulley, luphucule ukumelana nokuguguleka, ubushushu kunye nokumelana nokugqwala, lusetyenziswa kwi-mold yoomatshini, i-mold yeplastiki, ii-valve ezimelana nokugqwala, ukuprinta, ukucubungula kunye nokulinganisa i-pulley yelaphu kunye nephepha, umphezulu umhlophe wesilivere.
