ʻO ka valve palekana

ʻO nā ʻūhā palekana me nā bellow pale kaulike

ʻO ka bellows i loko o ka valve palekana nā hana penei:

1) nā puʻu kaulike: hōʻoiaʻiʻo i ka hana kūpono o ka valve palekana, hoʻopau a hoʻopaʻa i nā hopena o ka backpressure, hiki ke kau ʻia a kūkulu ʻia paha, i kahi waiwai i loko o nā palena i kuhikuhi ʻia. 

2) bellows pale: pale i ka milo, alakai milo a me ka aoao luna o ka valve palekana (me ka punawai) mai ka pili ana me process wai, e hōʻoia ana i ka pololei o nā ʻāpana neʻe a me ke kōkua ʻana i ka pale ʻana i nā pōʻino ma muli o ka cristallization a i ʻole polymerization, ka ʻino a i ʻole abrasion o nā mea i loko, hiki ke hoʻololi i ka hana pololei o ka pahu palekana.

Hiki i ka pneumatic actuator ke hoʻokiʻekiʻe piha ʻana i ka disc, kaohi mamao a kūʻokoʻa mai ke kaomi hana o ka process likua.

Paʻa pahu palekanaped me ka mea pale diski 

Besa hiki iā ia ke hoʻolako i kāna mau pahu palekana me ka "test gag", i loko o ʻelua mau wili, hoʻokahi ʻulaʻula a hoʻokahi ʻōmaʻomaʻo. ʻO ka wili ʻulaʻula, ʻoi aku ka lōʻihi ma mua o ka ʻōmaʻomaʻo, poloka i ka hoʻokiʻekiʻe ʻana o ka disc, e pale ana i ka wehe ʻana o ka valve.

ʻO ka hana hōʻailona hoʻokiʻekiʻe e ʻike i ka hāpai ʻana o ka disc, ʻo ia hoʻi ka wehe ʻana o ka valve. 

Paʻa pahu palekanaped me ka vibrations stabilizer

Hoʻemi ka vibration stabilizer i ka liʻiliʻi o nā oscillations a me nā haʻalulu i hiki ke hana i ka wā hoʻomaha, no ka hana pono ʻole o ka valve. 

ʻO nā kiwi hoʻopaʻa palekana sila kūpaʻa 

No ka loaʻa ʻana o kahi sila ʻoi aku ka maikaʻi ma waena o ka disc a me nā papa noho, hiki ke hoʻolako i ka valve me kahi sila paʻa. Keia hoʻonā i lawe 'ia ma hope o ka 'ike loea 'Oihana a me ka noonoo ana i ka hoʻoikaika kino kūlana: puʻe, wela, 'ano a me physical state o process waenakonu.

ʻO nā kīʻaha palekana me ka ʻaʻahu hoʻomehana

I ka hihia o ka media viscous loa, paʻa a hiki paha i ka crystallising, hiki ke hoʻolako ʻia ka valve palekana me ka ʻaʻahu hoʻomehana, ʻo ia kahi pahu kila kila i wili ʻia ma ke kino valve, hoʻopiha ʻia me kahi wai wela (ka mahu, ka wai wela, etc.) i mea e hōʻoiaʻiʻo i ka process hiki i ka media flowability ma o ka valve. 

ʻO nā ili hoʻopaʻa kila

No ka loaʻa ʻana o ka corrosion ʻoi aku ka maikaʻi a me ke kūpaʻa ʻana o ka disc a me nā wahi hoʻopaʻa noho, ma ke noi a ma hope o Tech. ʻO ka nānā ʻana o ka Dept., ua hoʻolako ʻia nā kiwi palekana me ka disc a me ka noho me nā ʻili hoʻopaʻa stellited. Manaʻo ʻia kēia hoʻonā inā loaʻa nā koina kiʻekiʻe a me ka wela, ka media abrasive, media me nā ʻāpana paʻa, cavitation. 

Besa ʻo nā pahu palekana CE PED hooiaioia

ka PED Hāʻawi ke kuhikuhi i ka mākaʻikaʻi ʻana i nā mea hana kaomi a me nā mea āpau kahi i ʻoi aku ka nui o ke kaomi ʻae ʻia (PS) ma mua o 0.5 bar. Pono ka nui o kēia mea hana e like me:

• nā kahua o ka hoʻohana ʻana (nā kaomi, nā mahana)
• nā ʻano wai i hoʻohana ʻia (wai, kinoea, hydrocarbons, etc.)
• ka nui / kaomi lākiō pono no ka noi

ʻO ka pahuhopu o Directive 97/23/EC e hoʻohui i nā kānāwai āpau o nā mokuʻāina o ka European Community e pili ana i nā mea kaomi. ʻO ka mea kūikawā, ua hoʻoponopono ʻia nā pae hoʻohālike no ka hoʻolālā, hana, kaohi, hoʻāʻo a me ke kahua o ka noi. Hāʻawi kēia i ka holo manuahi o nā mea paʻi a me nā mea pono.

Pono ke kuhikuhi i ka hoʻokō ʻana i nā koi palekana koʻikoʻi e pono ai ka mea hana e hoʻokō i nā huahana a me ka hana process. Pono ka mea hana e koho a hōʻemi i nā pilikia o ka huahana i kau ʻia ma ka mākeke.

Besa ʻo nā pahu palekana CE ATEX hooiaioia

ATEX - Nā lako no nā lewa hiki ke pahū (94/9/EC).

“Directive 94/9/EC, ʻike maikaʻi ʻia e ka acronym ATEX, ua hoʻokō ʻia ma Italia e ka Pelekikena Pelekikena 126 o 23 Malaki 1998 a pili i nā huahana i manaʻo ʻia no ka hoʻohana ʻana i nā lewa hiki ke pahū. Me ke komo ʻana i ka mana o ka ATEX Kuhikuhi, ka standUa hoʻopau ʻia nā palapala i mana mua ʻia a mai ka 1 Iulai 2003 ua pāpā ʻia ke kūʻai aku i nā huahana i kū ʻole i nā mea hou.

ʻO Directive 94/9/EC kahi kuhikuhi 'new approach' e manaʻo ana e ʻae i ka neʻe manuahi o nā waiwai i loko o ke Kaiaulu. Hoʻokō ʻia kēia ma ka hoʻohui ʻana i nā koi palekana kānāwai, ma muli o kahi ala e pili ana i ka pilikia. Ke manaʻo nei hoʻi e hoʻopau a i ʻole, e hōʻemi i nā pilikia e kū mai ana mai ka hoʻohana ʻana i kekahi mau huahana i loko a i ʻole e pili ana i kahi lewa hiki ke pahū. ʻO kēia
'o ia ho'i, pono e no'ono'o 'ia ka hiki 'ana mai o ka lewa pahū 'a'ole wale ma ke 'ano "ho'okahi" a mai ka mana'o pa'a, akā, nā kūlana hana a pau e hiki mai ana mai ka process pono no hoi e noonooia.
Hoʻopili ka Directive i nā lako, inā wale nō a i hui pū ʻia paha, i manaʻo ʻia no ka hoʻokomo ʻana i nā "zone" i helu ʻia he mea weliweli; nā ʻōnaehana pale e hoʻopau a paʻa paha; nā ʻāpana a me nā ʻāpana e pono ai i ka hana ʻana o nā lako a i ʻole nā ​​ʻōnaehana pale; a me ka hoʻoponopono a me ka hoʻoponopono ʻana i nā mea palekana pono a pono paha no ka hana palekana a hilinaʻi o nā lako a i ʻole nā ​​ʻōnaehana pale.

Ma waena o nā hiʻohiʻona hou o ka Directive, e uhi ana i nā pōʻino pahū o kēlā me kēia ʻano (electrical and non-electrical), pono e hōʻike ʻia kēia mau mea:
