ʻIke ʻia ʻo Mechanical seal ma ke ʻano he sila hope, nona nā maka hope e kū pono ana i ke axis o ka rotation, ka maka hope ma lalo o ka hana o ke kaomi wai a me ka uku ʻana i ka mechanical external force, e pili ana i ka hoʻonohonoho ʻana o ke sila kōkua a me ka. ʻē aʻe e mālama pono, a me ka paheʻe pili, i mea e pale ai i ka leakage wai. Hōʻuluʻulu ʻo Credo Pump i nā kumu leakage maʻamau o ka sila mechanical pump wai:


Kūlana leakage maʻamau

ʻO ka hapa o ka leakage seal mechanical e ʻoi aku ma mua o 50% o nā pauma mālama mālama. ʻO ka maikaʻi o ka hana o ka mechanical seal pili pono i ka hana maʻamau o ka paila. Ua hōʻuluʻulu ʻia a nānā ʻia penei:

 

1. Leakale manawa

Pump rotor shaft channel momentum, auxiliary sila a me ka nui keakea o ke kumu, ke apo neʻe hiki ole ke neʻe flexibly ma luna o ke kumu, i ka wa i hoohuliia ka pauma, ka dynamic a me static apo komo, aole uku hoʻoneʻe.

Nā mea e pale aku ai: I ka hui ʻana o ka sila mechanical, pono e emi ke kumu o ke kumu ma lalo o 0.1mm, a ʻo ka hoʻopili ʻana ma waena o ke sila kōkua a me ke kumu kūpono. ʻOiai e hōʻoiaʻiʻo ana i ka sila radial, hiki ke hoʻoneʻe ʻia ke apo hoʻoneʻe ma ke kumu ma hope o ka hui ʻana (hiki ke hoʻihoʻi ʻia ke apo hoʻoneʻe i ka pūnāwai).


2. ʻAʻole lawa ka ʻaila lubricating ma ka ʻili o ka sila e hoʻomaloʻo a huki paha i ka maka hope.

Nā mea e pale aku ai: Pono ke kiʻekiʻe o ke kiʻekiʻe o ka ʻaila lubricating i loko o ke keʻena ʻaila ma mua o ka ʻili hoʻopaʻa ʻana o nā apo neʻe a paʻa.


3. ʻO ka haʻalulu manawa o ka rotor. ʻO ke kumu, ʻaʻole kaulike ka stator a me nā uhi o luna a me lalo i ka impeller a me ka spindle, cavitation a i ʻole ka lawe ʻana i ka pōʻino (ʻaʻahu), e pōkole kēia kūlana i ke ola sila a me ka leakage.

Nā Kū'ē: Hiki ke hoʻoponoponoʻia nā pilikia i luna e like me nā kūlana mālama.


Leaka ma muli o ke kaomi

1. Mechanical seal leakage ma muli o ke kiʻekiʻe puʻe a me ka nalu puʻe ma muli o ka excessive punawai kiko'ī puʻe a me ka huina kiko'ī manao hoʻolālā a me ka puʻe i loko o ka sealing keʻena ma mua o 3MPa, e hana i ka kiko'ī puʻe ma ka sealing hope maka nui loa, e paʻakikī. no ka hoʻokumu ʻana o ke kiʻiʻoniʻoni wai, ʻaʻahu koʻikoʻi ma ka maka hope o ka sila, hoʻonui i ka waiwai calorific a me ka hopena i ka deformation thermal o ka ʻili hoʻopaʻa.

ʻO nā mea kū'ē: i loko o ka sila mīkini hui, pono e hoʻokō ʻia ka hoʻopili puna e like me nā mea i hoʻolako ʻia, ʻaʻole e ʻae i ka nui a i ʻole ka liʻiliʻi liʻiliʻi, nā kūlana kiʻekiʻe ma lalo o ka mechanical seal e hana i nā ana. I mea e hiki ai i ka hopena o ke alo ke kūpono, e like me ka hiki ke hōʻemi i ka deformation, hiki ke hoʻohana i ka alloy paʻakikī, nā seramika a me nā mea ʻē aʻe me ka ikaika compressive kiʻekiʻe, a hoʻoikaika i nā ana lubrication hoʻomaha, koho i ke ʻano hoʻouna, e like me ke kī, pine, etc.


2. ʻO ka hoʻokuʻu ʻia ʻana o ka leakage ʻenekini hoʻoheheʻe ʻia e ka hana i ke kaʻina o ka hoʻomaka ʻana, ka hoʻomaha ʻana, ma muli o ka blockage inlet pump, pumping medium i loko o ke kinoea, e hoʻokau i kahi puʻupuʻu hoʻopaʻa maikaʻi ʻole. ke kumu o na sila, kukulu-i loko o ke ano mechanical sila e hua mai (wai) o ka leak hanana, vacuum sila a me ka okoa o ka pai puʻe sila directional okoa o ka mea, a me ka adaptability o mechanical sila i kekahi kuhikuhi.

Countermeasure: e hoʻohana i ka sila ʻelua maka maka mechanical, he mea kōkua ia e hoʻomaikaʻi i ke kūlana lubrication a me ka hana sila.


Leakage i hana ʻia e ka waena

1. ʻO ka hapa nui o ka pauma submersible mechanical seal dismantling, static ring a me ka neʻe ʻana o ke apo auxiliary seals he inelastic, ua popopo kekahi, e hopena i ka nui o ka leakage o ka sila mīkini a hiki i ka wili ʻana i ke kumu. Ma muli o ke kiʻekiʻe o ka wela, ʻo ka waika nāwaliwali i loko o ka wai, nāwaliwali kumu ma ke apo paʻa a me ka neʻe ʻana o ke apo auxiliary rubber seal corrosion, ka hopena i ka leakag mechanical he nui loa, dynamic a me static ring rubber seal material no ka nitrile -- 40, kiʻekiʻe wela kū'ē, acid -alkali kū'ē, i ka wa a ka waiʻawaʻawa a me ka alkaline oluolu i corrosion.

Nā mea e pale aku ai: i ka media corrosive, ʻo nā ʻāpana lāʻau e pono ke kūpaʻa kiʻekiʻe i ka wela, ka pale ʻana i ka waika nāwaliwali, ka fluororubber alkali palupalu.


2. Mechanical leakage sila ma muli o ka paʻaʻeleʻele haumia. Inā ʻoki ʻia nā ʻāpana paʻa i ka maka sila, e ʻoki ʻia a wikiwiki paha i nā sila o ka lole a me ka waimaka, ka unahi a me ka hōʻiliʻili ʻana o ka aila ma ka ʻili o ke kumu (hoʻonohonoho), ma ka wikiwiki wikiwiki aʻe ma mua o ka hoʻohana ʻana i ka pae o ka friction pai, hiki ke apo. 't compensate displacement o abrasion, paakiki a paakiki piliki hana oi aku mamua o paakiki i ka graphite friction pai, no ka mea, ua hoʻokomo 'ia ka graphite sealing ring sealing surface.

Hoʻohālikelike: Pono e koho ʻia ka sila mechanical o ka tungsten carbide friction pair ma ke kūlana kahi e maʻalahi ai nā ʻāpana paʻa e komo.


Ma muli o nā pilikia ʻē aʻe i hoʻokumu ʻia e ka leakage o nā sila mechanical e noho mau nei i ka hoʻolālā, koho, hoʻonohonoho a me nā wahi kūpono ʻole.

1. Pono e hoʻokō ʻia ka paʻi puna e like me nā lula, ʻaʻole ʻae ʻia e nui a liʻiliʻi paha. ʻO ± 2mm ka hewa.

2. ʻO ka maka hope o ka lāʻau (a i ʻole ka lima lima) e hoʻokomo ana i ke apo hoʻopaʻa apo hoʻoneʻe a me ka maka hope o ke apo seal gland (a i ʻole ka pūpū) e hoʻokomo ana i ke apo seal static e pono e chamfered a hoʻomaʻamaʻa i mea e pale aku ai i ka pōʻino o ke apo hoʻopaʻa hoʻopaʻa sila i ka wā o ka hui.
