Nā ʻanuʻu hoʻomaʻemaʻe a me nā pono hui no ka hoʻomaʻemaʻe valve

1. Hoʻomaʻemaʻe ʻana no ka hoʻomaʻemaʻe ʻana i ka valve:

Pono e mālama ʻia nā ʻāpana degreased o ka valve i kēia kaʻina hana ma mua o ka hui ʻana:

(1) E like me nā koi hoʻoponopono, pono e hoʻoliʻi ʻia kekahi mau ʻāpana valve me ka ʻole o ka machining burrs ma ka ʻili;

(2) E hoʻohaʻahaʻa i nā ʻāpana valve a pau;

(3) E hoʻokō ʻia ka pickling a me ka passivation ma hope o ka degreasing (ʻaʻohe phosphorus ka mea hoʻomaʻemaʻe);

(4) Ma hope o ka pickling a me ka passivation, holoi me ka wai i hoʻomaʻemaʻe ʻia me ka ʻole o ke koena reagent (ua waiho ʻia kēia hana no nā ʻāpana kila kalapona);

(5) E holoi maloʻo ʻia kēlā me kēia ʻāpana valve me ka lole i ulana ʻole ʻia, a ʻaʻole e mālama ʻia ka ʻili o nā ʻāpana e like me ka hulu uea, a i ʻole e puhi ʻia me ka nitrogen maʻemaʻe;

(6) E holoi i kēlā me kēia ʻāpana valve me ka lole ʻaʻole i ulana ʻia a i ʻole ka pepa kānana pololei i hoʻopaʻa ʻia me ka waiʻona maʻemaʻe analytical a hiki i ka loaʻa ʻole o ke kala lepo.

2. Nā koi hui no ka degreasing valves

Pono e hoʻopaʻa ʻia a mālama ʻia nā ʻāpana i hoʻomaʻemaʻe ʻia o ka valve degreasing no ke kau ʻana. ʻO nā koi no ke kaʻina hana e like me kēia:

(1) Pono e hoʻomaʻemaʻe ʻia ka hale hana hoʻoheheʻe degreasing valve, a i ʻole kahi wahi maʻemaʻe pōkole (e like me ka lole kala i kūʻai hou ʻia a i ʻole ke kiʻiʻoniʻoni plastik) pono e kūkulu ʻia i mea e pale aku ai i ke komo ʻana o ka lepo i ka wā e hoʻokomo ai i ka valve.

(2) Pono nā limahana o ka hui e komo i nā lole pulupulu maʻemaʻe, nā pāpale pulupulu maʻemaʻe, ʻaʻohe leaka lauoho, nā kāmaʻa maʻemaʻe a me nā mīkina lima plastik (degreasing).

(3) Pono e hoʻomaʻemaʻe a hoʻomaʻemaʻe ʻia nā mea hana hui ma mua o ka hui ʻana o ka valve degreasing e hōʻoia i ka maʻemaʻe.
