1. ʻIke hewa a me ka mālama ʻana
1. Hana hewa ʻole a hana ʻole paha
ʻO nā kumu a me nā ʻano lapaʻau penei:
(1) Paʻa ke kumu valve a paʻa paha ka puka valve. Ke hoʻopaʻa ʻia ka valve kahe a i ʻole ka pahu pahu kuhikuhi a i ʻole ke pani ʻia ka lua valve, hiki ke hana hewa ka cylinder hydraulic. I kēia manawa, e nānā i ka haumia o ka ʻaila; e nānā inā paʻa ka lepo a i ʻole nā waihona colloidal i loko o ke kumu valve a i ʻole e ālai i ka lua valve; e nānā i ka ʻaʻahu o ke kino valve, hoʻomaʻemaʻe a hoʻololi i ka kānana ʻōnaehana, hoʻomaʻemaʻe i ka pahu ʻaila, a hoʻololi i ke ʻano hydraulic.
(2) Paʻa ke koʻokoʻo piston a me ka cylinder a i ʻole ke kāohi ʻia ka cylinder hydraulic. I kēia manawa, ʻaʻole e neʻe a neʻe iki paha ka hydraulic cylinder. I kēia manawa, e nānā inā paʻa loa nā sila o ka piston a me ka piston rod, inā paha i komo ka lepo a me nā waihona colloidal: inā paha i kulike ka laina axis o ke koʻokoʻo piston a me ka pahu cylinder, inā ʻaʻole kūpono nā ʻāpana a me nā sila, a inā paha. nui loa ka ukana. Nui.
(3) He haʻahaʻa loa ke kaomi mana o ka ʻōnaehana hydraulic. ʻOi aku ka nui o ke kūpaʻa throttling i ka pipeline control, hoʻoponopono pono ʻole ʻia ka valve kahe, ʻaʻole kūpono ke kaomi hoʻomalu, a hoʻopilikia ʻia ke kumu kaomi. I kēia manawa, e nānā i ke kumu kaomi hoʻomalu e hōʻoia i ka hoʻololi ʻana o ke kaomi i ka waiwai i kuhikuhi ʻia o ka ʻōnaehana.
(4) Komo ka ea i ka ʻōnaehana hydraulic. ʻO ka mea nui ma muli o nā leaks i loko o ka ʻōnaehana. I kēia manawa, e nānā i ke kiʻekiʻe o ka wai o ka pahu aila hydraulic, nā sila a me nā hui paipu ma ka ʻaoʻao hoʻoheheʻe o ka paila hydraulic, a inā he lepo loa ka ʻaila ʻaila. Inā pēlā, pono e hoʻohui ʻia ka aila hydraulic, pono e mālama ʻia nā sila a me nā hui paipu, a hoʻomaʻemaʻe ʻia ka mea kānana koʻikoʻi.
(5) Ua lohi ka neʻe mua o ka cylinder hydraulic. I ka hihia o ka haʻahaʻa haʻahaʻa, ʻo ka ʻaila hydraulic he viscosity kiʻekiʻe a me ka wai maikaʻi ʻole, kahi e neʻe mālie ai ka cylinder hydraulic. ʻO ke ala hoʻomaikaʻi ke hoʻololi i ka aila hydraulic me ka maikaʻi o ka viscosity a me ka hana wela. Ma nā haʻahaʻa haʻahaʻa, e hoʻohana i kahi mea hoʻomehana a hoʻohana paha i ka mīkini e wela iā ia e hoʻonui i ka mahana o ka aila i ka hoʻomaka. Pono e mālama ʻia ka mahana aila hana maʻamau o ka ʻōnaehana ma kahi o 40 ° C.
2. ʻAʻole hiki ke hoʻokele i ka ukana i ka wā e hana ai
ʻO nā hiʻohiʻona nui he kū pololei ʻole o ke koʻokoʻo piston, lawa ʻole ka pahu, hoʻemi ʻia ka wikiwiki, hana paʻa ʻole, etc. ʻO nā kumu:
(1) Leakage i loko o ka hydraulic cylinder. ʻO ka leaka o loko o ka hydraulic cylinder e pili ana i ka leakage i hana ʻia e ka hydraulic cylinder body seal, ke sila o ke koʻokoʻo piston a me ka uhi hoʻopaʻa ʻana, a me ka ʻaʻahu nui o ka sila piston.
ʻO ke kumu o ka leakage o ka sila ma waena o ke koʻokoʻo piston a me ka uhi sila, ʻo ia ka wīwī ʻana o ka sila, ʻokiʻoki, haehae, ʻāʻī, ʻelemakule, deteriorated, deformed, etc. I kēia manawa, pono e hoʻololi ʻia kahi sila hou.
ʻO ke kumu nui o ka hoʻohana nui ʻana i ka sila piston ka hoʻoponopono kūpono ʻole o ka valve control speed, ka hopena o ka hoʻihoʻi nui ʻana a me ka hoʻokomo pono ʻole ʻana o ka sila a i ʻole ka haumia o ka ʻaila hydraulic. ʻO ka lua, ʻo ke komo ʻana o nā mea ʻē i ka wā o ka hui ʻana a ʻaʻole maikaʻi ka maikaʻi o ka mea hoʻopaʻa. ʻO ka hopena ka neʻe mālie a me ka nāwaliwali. I nā hihia koʻikoʻi, e hōʻeha ia i ka piston a me ka cylinder, e hana ana i ke ʻano o ka "huki cylinder". ʻO ke ʻano o ka mālama ʻana, ʻo ia ka hoʻoponopono ʻana i ka valve control speed, a hana i nā hana kūpono a me nā hoʻomaikaʻi e like me nā ʻōlelo kuhikuhi.
(2) Leakage o ke kaapuni hydraulic. Me ka leakage o nā valves a me nā laina hydraulic. ʻO ke ʻano o ka mālama ʻana, ʻo ia ke nānā a hoʻopau i ka leakage o ka pipeline pili hydraulic ma ka hana ʻana i ka valve reversing.
(3) Hoʻihoʻi ʻia ka ʻaila hydraulic i ka pahu ʻaila ma o ka ʻauwaʻa overflow. Inā komo ka lepo i loko o ka valve overflow a hoʻopaʻa i ka spool, e wehe maʻamau ka ʻaila wai, e kāpae ka ʻaila hydraulic i ka valve overflow a hoʻi pololei i ka pahu aila, ʻaʻohe aila e komo i ka cylinder hydraulic. Inā ʻoi aku ka nui o ka ukana, ʻoiai ua hōʻea ke kaomi hoʻoponopono o ka pahu hoʻomaha i ka helu helu kiʻekiʻe, ʻaʻole hiki i ka hydraulic cylinder ke loaʻa i ke koi no ka hana mau a ʻaʻole e neʻe. Inā haʻahaʻa ke kaomi hoʻololi, ʻaʻole hiki ke hoʻokō ʻia ka ikaika vertebral no ka hoʻouka ʻana ma muli o ka lawa ʻole o ke kaomi, i hōʻike ʻia me ka lawa ʻole o ka pahu. I kēia manawa, e nānā a hoʻoponopono i ka valve overflow.
3. Pahee a kolo paha ka piston
ʻO ka hoʻoheheʻe ʻana a i ʻole ke kolo ʻana o ka piston hydraulic cylinder e hana paʻa ʻole ka hana hydraulic cylinder. ʻO nā kumu nui penei:
(1) Ua lohi ka loko o ka cylinder hydraulic. ʻO nā ʻāpana o loko o ka hydraulic cylinder ʻaʻole i hui pono ʻia, ua deformed nā ʻāpana, ʻaʻahu, a i ʻole ka hoʻomanawanui geometric ma mua o ka palena, a ʻoi aku ka nui o ke kūpaʻa hana, no laila e hoʻololi ka piston piston o ka hydraulic cylinder me ke kūlana stroke, a pahee a kolo paha. ʻO ke kumu ma muli o ka maikaʻi ʻole o ka hui ʻana o nā ʻāpana, nā ʻili o ka ʻili a i ʻole nā mea hao i hana ʻia e ka sintering, e hoʻonui ai i ke kū'ē a hoʻemi i ka wikiwiki. No ka laʻana: ʻaʻole concentric ka piston a me ke koʻokoʻo piston a i ʻole ke kuʻi ʻana o ke koʻokoʻo piston, ua hoʻopaʻa ʻia ke kūlana hoʻokomo o ka cylinder hydraulic a i ʻole ke koʻokoʻo piston ma ke ala alakaʻi, ua hoʻokomo ʻia ke apo hoʻopaʻa paʻa a paʻa paha, etc. ʻO ka hoʻonā e hoʻoponopono a hoʻoponopono, hoʻololi i nā ʻāpana ʻino a wehe i nā faila hao.
(2) ʻO ka lubrication maikaʻi ʻole a i ʻole ka hoʻomaʻamaʻa ʻana i waho o ka ʻilihune o ke anawaena o ka lua o ka cylinder hydraulic. No ka mea, ʻo ka piston a me ka cylinder, ke alakaʻi alakaʻi a me ke koʻokoʻo piston e pili ana i ka neʻe ʻana, inā ʻilihune ka lubrication a i ʻole ka ʻilihune o ka pahu hydraulic cylinder, e hōʻeha ia i ka ʻaʻahu a hōʻemi i ka linearity o ka laina kikowaena cylinder. Ma kēia ala, i ka wā e hana ana ka piston i loko o ka hydraulic cylinder, ʻoi aku ka nui o ke kūpaʻa frictional a liʻiliʻi i kekahi manawa, e hoʻoheheʻe a kolo paha. ʻO ke ʻano o ka hoʻopau ʻana, ʻo ia ka wili mua ʻana i ka cylinder hydraulic, a laila hoʻomākaukau i ka piston e like me nā koi hoʻohālikelike, wili i ke koʻokoʻo piston, a hoʻonohonoho i ka lima alakaʻi.
(3) Hoʻokomo ka paila hydraulic a i ʻole hydraulic cylinder i ka lewa. ʻO ka hoʻoemi a i ʻole ka hoʻonui ʻia ʻana o ka ea hiki ke hoʻoheheʻe a kolo paha ka piston. ʻO nā hana hoʻoponopono pilikia e nānā i ka paila hydraulic, hoʻonohonoho i kahi mea hoʻopau kūikawā, a hoʻohana wikiwiki i ka hoʻopau no nā manawa he nui i ka wā holoʻokoʻa.
(4) ʻO ka maikaʻi o ka sila e pili pono ana i ka paheʻe a i ʻole ke kolo. Ke hoʻohana ʻia ka sila O-ring ma lalo o ke kaomi haʻahaʻa, ke hoʻohālikelike ʻia me ka sila U-like, ma muli o ke kiʻekiʻe o ka ʻili o ka ʻili a me ka ʻokoʻa nui o ka ikaika a me ke kūpaʻa friction kūʻē, ua maʻalahi ka paheʻe a kolo paha; ke piʻi aʻe ka paʻi o ka ʻili U-like me ke kaomi. Ma muli o ka piʻi ʻana o ke kūpaʻa hoʻopili ʻana o ka lehelehe, e hili ke apo hoʻopaʻa ʻana a hoʻonui ka lehelehe. He mea maʻalahi hoʻi ka paheʻe ʻana a me ka kolo. No ka pale ʻana i ka hili ʻana, hiki ke hoʻohana ʻia ke apo kākoʻo e paʻa.
