Automation Encyclopedia: Hoʻomaopopo i ka IP Protection Ratings

Ke koho ʻana i nā mea hana ʻenehana, ua ʻike paha ʻoe i nā lepili e like me IP65 a i ʻole IP67. Hōʻike kēia alakaʻi i nā helu palekana IP e kōkua iā ʻoe e koho i ka lepo lepo a me nā pā wai kūpono no nā kaiapuni ʻoihana.

1. He aha ka helu IP?

Kū ka IP no Ingress Protection, kahi kūlana honua i wehewehe ʻia e IEC 60529. Hoʻokaʻawale ʻo ia i ka maikaʻi o ka pale ʻana o ka pā uila i ke komo ʻana mai:

Nā ʻāpana paʻa (e like me ka lepo, nā mea hana, a i ʻole nā manamana lima)
ʻO nā wai (e like me ka ua, nā ʻōpala, a i ʻole ka hoʻopaʻa ʻia)

ʻO kēia ka mea i kūpono i nā polokalamu i helu ʻia IP65 no ka hoʻokomo ʻana i waho, nā hale hana lepo lepo, a me nā wahi pulu e like me nā laina hana meaʻai a i ʻole nā mea kanu kemika.

2. Pehea e heluhelu ai i ka helu IP

ʻElua helu helu IP code:

Hōʻike ka huahelu mua i ka pale ʻana i nā mea paʻa
Hōʻike ka huahelu ʻelua i ka pale ʻana i ka wai

ʻO ke kiʻekiʻe o ka helu, ʻoi aku ka nui o ka pale.

Laʻana:

IP65 = Paʻa lepo (6) + Pale ʻia mai nā pahu wai (5)

IP67 = Paʻa i ka lepo (6) + Pale ʻia mai ka hoʻopaʻa ʻana no ka manawa pōkole (7)

3. Kūlana Kūlana Palekana

Palekana ʻĀpana Paʻa (Huku Mua)

(Hōʻike ka helu mua i ka pale ʻana i nā mea paʻa)

Heluhelu	ʻO ka wehewehe ʻana i ka pale
0	ʻAʻohe pale
1	Nā mea ≥ 50 mm
2	Nā mea ≥ 12.5 mm
3	Nā mea ≥ 2.5 mm
4	Nā mea ≥ 1 mm
5	Pale lepo
6	Paʻa lepo

ʻO ka hoʻopalekana ʻana o ka wai (Hui ʻelua)

(Hōʻike ka helu ʻelua i ka pale ʻana i ka wai)

Heluhelu	ʻO ka wehewehe ʻana i ka pale
0	ʻAʻohe pale
1	wai kulu
2	ʻO ka kulu wai ke hili ʻia
3	ʻūpī wai
4	wai paʻipaʻi
5	ʻO nā pahu wai haʻahaʻa haʻahaʻa
6	Nā mokulele ikaika
7	ʻO ka luʻu manawa
8	ʻO ka hoʻomau mau ʻana

5. Nā helu IP maʻamau a me nā hihia hoʻohana maʻamau

Ka helu IP	E hoʻohana i ka wehewehe ʻana i ka hihia
IP54	ʻO ka pale māmā no nā kaiapuni o loko
IP65	ʻO ka pale paʻa o waho i ka lepo a me ka wai
IP66	ʻO ka holoi ʻana a i ʻole ka ʻike ʻana i ka ua nui
IP67	ʻO ka luʻu manawa (e laʻa, i ka wā hoʻomaʻemaʻe a i ʻole ke kahe ʻana)
IP68	Hoʻohana mau ʻia ma lalo o ka wai (e laʻa, nā mea ʻike hoʻoheheʻe ʻia)

6. Ka hopena

Pono ka hoʻomaopopo ʻana i nā helu IP no ka pale ʻana i nā mea hana mai nā pōʻino o ke kaiapuni a me ka hōʻoia ʻana i ka hilinaʻi lōʻihi. Ke koho ʻana i nā mea hana no ka automation, instrumentation, a i ʻole ka hoʻomalu ʻana i ke kahua, e hoʻohālikelike mau i ka code IP i ke kaiapuni noi.

Ke kānalua ʻoe, e nānā i ka ʻikepili pūnaewele a i ʻole e kūkākūkā me kāu mea hoʻolako loea e hōʻoia i ka hoʻokō ʻana i nā koi o kāu pūnaewele.
