Pehea e koho pololei ai i ka aila hydraulic no nā kaomi hydraulic

ʻO kakaomi hydraulic ʻehā kolamuhāʻawi i ka ʻaila hydraulic i ka poloka valve ma lalo o ka hana a ka ʻaila ʻaila.Mālama ka ʻōnaehana hoʻokele i kēlā me kēia valve i hiki i ka ʻaila hydraulic kiʻekiʻe ke piʻi i nā keʻena luna a me lalo o ka cylinder hydraulic, e koi ana i ka hydraulic press e neʻe.ʻO ka hydraulic press kahi mea e hoʻohana ai i ka wai e hoʻouna i ke kaomi.

He mea koʻikoʻi ka ʻaila hydraulic no nā kaomi hydraulic ʻehā kolamu a ʻo ia kekahi o nā mea koʻikoʻi e hōʻemi i ka lole mīkini.ʻO ke kohoʻana i kaʻaila hydraulic kūpono e pili pono ana i ke ola lawelawe o ka mīkini hydraulic.

Ke koho ʻana i ka aila no kahi kaomi hydraulic ʻehā kolamu, pono ʻoe e koho mua i ka viscosity kūpono.ʻO ke koho ʻana o ka ʻaila viscosity e noʻonoʻo i nā ʻano hana, ka mahana hana a me ke kaomi hana o ka ʻōnaehana hydraulic.I loko o ka ʻōnaehana hoʻoili hydraulic, ʻo ka ʻaila ʻaila kekahi o nā mea koʻikoʻi loa i nā loli i ka viscosity aila hydraulic.Loaʻa i nā ʻano pauma like ʻole ka liʻiliʻi a me ka viscosity ʻae ʻia.I mea e hōʻemi ai i ka hoʻohana ʻana i ka mana, pono e hoʻohana ʻia ka aila me ka viscosity haʻahaʻa e like me ka hiki.Eia naʻe, i mea e lubricate ai i nā ʻāpana koʻikoʻi a pale i ka leakage, pono e koho ʻia ka aila hydraulic o ka viscosity kūpono.

1. Hydraulic aila kumu hoʻohālike

Hoʻokaʻawale ʻia nā ʻano ʻaila hydraulic i ʻekolu mau ʻano maʻamau: ʻano HL, ʻano HM, a me ke ʻano HG.

(1) Hoʻokumu ʻia ka ʻaila hydraulic ʻano HL mai kahi ʻaila kumu hoʻomaʻemaʻe kiʻekiʻe kiʻekiʻe, me nā mea antioxidant a me nā anti-rust additives.E like me ka neʻe ʻana ma 40 degere Celsius, hiki ke hoʻokaʻawale ʻia ka viscosity i ʻeono papa: 15, 22, 32, 46, 68, a me 100.
(2) Aia nā ʻano HM i nā ʻano alkaline kiʻekiʻe, alkaline haʻahaʻa zinc, neutral kiʻekiʻe zinc a me nā ʻano lehu.Wahi a ka neʻe ʻana ma 40 degere Celsius, ua māhele ʻia ka viscosity i ʻehā mau papa: 22, 32, 46, a me 68.
(3) Loaʻa i ke ʻano HG nā waiwai anti-rust a me nā anti-oxidation.Eia kekahi, ua hoʻohui ʻia kahi mea hoʻomaikaʻi viscosity index, nona nā ʻano wela viscosity maikaʻi.

2. Hoʻohana ʻia ka ʻaila Hydraulic

(1) Hoʻohana ʻia ka ʻaila hydraulic HL no ka lubrication i nā pahu pahu a me nā ʻōnaehana kahe haʻahaʻa haʻahaʻa o nā mea mīkini like ʻole kahi i loaʻa ʻole nā ​​koi kūikawā no ka ʻaila a ʻoi aku ka mahana o ka ambient ma luna o zero degere Celsius.ʻO ia mau huahana i loaʻa i ka hiki ke hoʻopili maikaʻi ʻia, a hiki i ka mahana hana kiʻekiʻe ke piʻi i 80 degere Celsius.
(2) Hoʻohana nui ʻia ka ʻaila hydraulic HM i nā ʻōnaehana hydraulic o nā puʻupuʻu kaumaha, medium-pressure a me ke kiʻekiʻe-pressure vane pumps, plunger pumps and gear pumps.Eia hou, ua kūpono kēiaʻano o kaʻaila hydraulic no nā mea hoʻolālā kiʻekiʻe a me nā'ōnaehana hydraulic kaʻa.
(3) HG hydraulic aila he anti-rust maikaʻi, anti-oxidation, anti-wear, a me nā waiwai anti-stick-slip, no laila ua kūpono ia no nā ʻōnaehana lubrication e hoʻohana ana i nā hydraulics mea hana mīkini a me nā ala alakaʻi.

ʻO nā mahana hana o nā aila hydraulic o nā māka viscosity like ʻole ma lalo o nā koi like ʻole.

Nui nā ʻano ʻaila hydraulic ma ka mākeke, a he nui nō hoʻi nā ʻano mīkini hydraulic.ʻOiai ua like nā hana o ka aila hydraulic, pono e koho i nā ʻaila hydraulic ʻē aʻe no nā mīkini hydraulic ʻē aʻe.Ke koho ʻana i ka ʻaila hydraulic, pono e hoʻomaopopo nā limahana i ka mea i noi nui ʻia e hana, a laila koho i ka ʻaila hydraulic kūpono no ka mīkini hydraulic.

Pehea e koho ai i ka ʻaila Hydraulic pono no ka hydraulic Press

Hoʻohana pinepine ʻia nā ʻano ʻelua i ke koho ʻana i ka aila hydraulic.ʻO kekahi e koho i ka aila hydraulic e like me nā ʻano ʻaila a me nā kikoʻī i ʻōlelo ʻia e nā mea hoʻohālike a i ʻole nā ​​ʻōlelo kuhikuhi a ka mea hana paʻi hydraulic.ʻO ka mea ʻē aʻe e noʻonoʻo pono i ke koho ʻana o ka aila hydraulic e pili ana i nā kūlana kikoʻī o ka mīkini hydraulic, e like me ke kaomi hana, ka mahana hana, ka wikiwiki o ka neʻe ʻana, ke ʻano o nā mea hydraulic a me nā mea ʻē aʻe.

Ke kohoʻana,ʻo nā hana nui e hanaʻia: ka hoʻoholoʻana i ka laulā viscosity o kaʻaila hydraulic, ke kohoʻana i nāʻanoʻaila hydraulic kūpono, a me ka hālāwaiʻana i nā pono kūikawā o ka'ōnaehana hydraulic.
E koho maʻamau e like me kēia mau ʻano:

(1) E like me nā koho like ʻole o ka mīkini hana hydraulic press

Loaʻa i nā mīkini kikoʻī a me nā mīkini maʻamau nā koi viscosity ʻokoʻa.I mea e pale aku ai i ka deformation o nā ʻāpana mīkini ma muli o ka piʻi ʻana o ka mahana a pili i ka pololei o ka hana, pono e hoʻohana nā mīkini kikoʻī i ka aila hydraulic me ka haʻahaʻa haʻahaʻa.

(2) E koho e like me ke ʻano o ka paila hydraulic

ʻO ka paila hydraulic kahi mea nui o ka mīkini hydraulic.I loko o ka hydraulic press, ua kiʻekiʻe ka wikiwiki o ka neʻe ʻana, ke kaomi a me ka piʻi ʻana o ka mahana, a ua lōʻihi kona manawa hana, no laila ʻoi aku ka paʻakikī o nā koi no ka viscosity.No laila pono e noʻonoʻo ʻia ka paila hydraulic i ke koho ʻana i ka viscosity.

(3) E koho e like me ke kaomi hana o ka hydraulic press

Ke kiʻekiʻe ke kaomi, pono e hoʻohana ʻia ka aila me ka viscosity kiʻekiʻe e pale i ka leakage ʻōnaehana nui a me ka haʻahaʻa haʻahaʻa.Ke haʻahaʻa ke kaomi hana, ʻoi aku ka maikaʻi o ka hoʻohana ʻana i ka ʻaila me ka viscosity haʻahaʻa, hiki ke hōʻemi i ka nalo ʻana.

(4) E noʻonoʻo i ka mahana hana o ka mīkini hydraulic

Hoʻololi nui ka viscosity o ka ʻaila mineral ma muli o ka hopena o ka mahana.I mea e hōʻoiaʻiʻo ai i kahi viscosity kūpono i ka mahana hana, pono e noʻonoʻo ʻia ka mana o ka mahana ambient a puni.

(5) E noʻonoʻo i ka wikiwiki o ka neʻe ʻana o nā ʻāpana hana o ka mīkini hydraulic

Ke kiʻekiʻe loa ka wikiwiki o ka neʻe ʻana o nā ʻāpana hana i ka ʻōnaehana hydraulic, ʻoi aku ka haʻahaʻa o ka kahe o ka aila, piʻi ka pohō hydraulic me ka maʻalahi, a ʻoi aku ka liʻiliʻi o ka leakage, no laila ʻoi aku ka maikaʻi o ka hoʻohana ʻana i ka ʻaila me ka viscosity haʻahaʻa.

(6) E koho i ke ʻano kūpono o ka ʻaila hydraulic

ʻO ke koho ʻana i ka aila hydraulic mai nā mea hana maʻamau hiki ke hōʻemimīkini paʻi hydraulicnā hemahema a hoʻonui i ke ola o ka mīkini paʻi.
