6. Alloy Alloy

Zvishandiso zvinoshandiswa zvinoshandiswa nemhapu yemhanguzi ndeye 6-6-3 tin Bronze uye 58-2-2 Mangwana Brass. Copper Alloy ine yakanaka kupfeka kurwisa uye yakakodzera mvura uye steam ine tembiricha t≤200℃uye zita rekudzvinyirira PN≤1.6mpa. Zvinowanzoshandiswa mumavha mavharugedhi, mavhavha epasi rose, tarisa mavharuvhu, plug mavharuvhu, nezvimwe.

7. Chrome Stainless Simbi

Iwo anowanzoshandiswa mamakisi eChromium stainless simbi ndeye 2cr13 ne3CR33, ayo akaderedzwa uye akatsamwa, uye ane basa rakanaka rekushora. Inowanzoshandiswa pamavhiri emvura, steam uye petroleum ne tembiricha t≤450℃uye zita rekudzvinyirira PN≤32mpa.

8. Chrome-nickel-titanium stainless simbi

Giredhi rinowanzoshandiswa reChromium-nickel - Titanium Stainless Simbi ndeye 1cr18ni9ti, iyo ine basa rakanaka rekushora, kurwisa kupesana uye kupisa kupokana. Izvo zvakakodzera kuti muputi uye mamwe midhiya ne tembiricha t≤600°C uye kudzvanywa kwezita PN≤6.4mpa, uye inoshandiswa kune vagari vepasi, mavharuvhu, nezvimwewo

9. Nitriding simbi

10. Broning

Kubatanidza zvakananga maitiro ekuisa chisimbiso kubva pazvinhu zvevhuviri muviri kana disc mutumbi, uye wozoita maroni ekurapa. Iyo yekuisa chisimbiso ine zvakanaka kupfeka kurwisa. Nekuti simba renji blowdown vharuvhu.

Kana vharuvhu iri kushandiswa, izvo zvinhu zvinofanirwa kutarisirwa kuti zviite seanotevera:

1. Kubata chisimbiso chevharuvhu kunofanirwa kuedzwa kuti uve nechokwadi chekuita kwayo.

2. Tarisa uone kuti chisimbiso chevharuvhu chakapfekwa, uye chigadzirise kana kuitsiva zvinoenderana nemamiriro ezvinhu.
