I nā kaʻa hou, nā tractor a me nā mea hana ʻē aʻe, hoʻohana nui ʻia nā ʻōnaehana hydraulic like ʻole.ʻO kahi hana koʻikoʻi i ka hana ʻana o kēia mau ʻōnaehana e pāʻani ʻia e nā sensor-hydraulic alarms - heluhelu i nā mea āpau e pili ana i kēia mau mea, kā lākou mau ʻano, hoʻolālā a me ka hana, a me ke koho ʻana a me ka hoʻololi ʻana o nā sensor, ma ka ʻatikala.
He aha ke ʻano o ka mea ʻike alarm hydraulic?
ʻO ka mea sensor-hydrosignaling (sensor-relay, sensor-indicator o ka pae wai) - kahi mea o ka mana uila, ka nānā ʻana a me nā ʻōnaehana hōʻike o nā ʻōnaehana hydraulic o nā kaʻa;He mea ʻike paepae e hoʻouna ana i kahi hōʻailona i kahi hōʻailona a i ʻole mea hoʻokele (s) ke hiki ka wai i kahi pae paepae i koho mua ʻia.
I loko o kēlā me kēia kaʻa he nui nā ʻōnaehana hydraulic a me nā ʻāpana: nā ʻōnaehana hydraulic mana (i nā kaʻa, nā tractors a me nā mea hana like ʻole), lubrication a me nā ʻōnaehana hoʻoluʻu o ka mana mana, ʻōnaehana lako mana, nā mea holoi puka makani, ka hoʻokele mana a me nā mea ʻē aʻe.I kekahi mau ʻōnaehana, pono e nānā mau ʻia ka pae wai (e like me ka pahu wahie), aʻo nā mea ʻē aʻe he pono wale nō e kiʻi i ka ʻike e pili ana i ka hele ʻana a i ʻole ka nele o ka wai, a i ʻole e pili ana i ka wai e lanakila ana i kahi pae (ʻoi aʻe a hāʻule paha). .Hoʻoholo ʻia ka hana mua e nā mea ʻike pae hoʻomau, a no ka lua, hoʻohana ʻia nā mea ʻike hoʻāla hydraulic (DGS) a i ʻole nā mea ʻike wai.
Hoʻokomo ʻia ʻo DGS i nā pahu hoʻonui, pahu pahu mīkini a me nā mea ʻē aʻe o nā ʻōnaehana hydraulic.Ke piʻi ka wai i kahi pae, hoʻomaka ka sensor, pani a wehe paha i ke kaapuni, e hāʻawi ana i kahi hōʻailona on/off ma ka dashboard (no ka laʻana, kahi hōʻailona hoʻoheheʻe aila), a i ʻole ka hoʻohuli ʻana a i ʻole nā mea hana - pumps, drives and nā mea'ē aʻe e hāʻawi i ka hoʻololi i ka pae wai a iʻole ka hoʻololiʻana i keʻano hana o ka'ōnaehana hydraulic holoʻokoʻa.ʻO ia ke kumu i kapa pinepine ʻia ai ʻo DGS he sensor-signaling device a sensor-relays.
Ma nā lako kaʻa kaʻa hou, hoʻohana ʻia nā ʻano sensor-hydraulic alarm - pono e wehewehe ʻia i nā kikoʻī.
ʻO nā ʻano a me nā hiʻohiʻona o nā mea ʻike hoʻāla hydraulic
Hoʻokaʻawale ʻia nā mea ʻike o kēia lā i kekahi mau ʻano e like me ke kumu kino o ka hana, ke ʻano hana (ʻano wai) a me kāna mau hiʻohiʻona, ke kūlana maʻamau o nā pilina, ke ʻano pili a me nā ʻano uila.
Wahi a ke kumu o ka hana kino, ua māhele ʻia ka DGS automotive i ʻelua pūʻulu:
● conductometric;
● Lanakila.
Hoʻolālā ʻia nā mea ʻike Conductometric e hana me nā wai conductive uila (ka nui o ka wai a me nā mea hoʻoluʻu).ʻO kēia mau DGS e ana i ke kū'ē uila ma waena o ka hōʻailona a me nā electrodes maʻamau, a i ka wā e hāʻule nui ai ke kū'ē, e hoʻouna i kahi hōʻailona i kahi mea hōʻailona a mea hana.Aia kekahi mea ʻike conductivity i kahi ʻimi metala (i hana mau ʻia me ke kila kuhili ʻole) a me kahi kaapuni uila (ua komo pū me ka pulse generator a me kahi hōʻailona hōʻailona).Hana ka probe i nā hana o ka electrode mua, ua hāʻawi ʻia nā hana o ka electrode lua i ka ipu me ka wai (inā he metala) a i ʻole kahi ʻāpana metala i waiho ʻia ma lalo a i ʻole nā paia o ka ipu.Ke hana maʻalahi ka mea ʻike conductometric: inā aia ka pae wai ma lalo o ka ʻimi, ʻo ke kūpaʻa uila i ka palena ʻole - ʻaʻohe hōʻailona ma ka puka o ka mea ʻike, a i ʻole he hōʻailona e pili ana i kahi pae wai haʻahaʻa;I ka hiki ʻana o ka wai i ka ʻimi sensor, hāʻule nui ke kū'ē (e alakaʻi ka wai i kēia manawa) - ma ka puka o ka sensor, hoʻololi ka hōʻailona i ka ʻaoʻao.
Hiki i nā mea ʻike lele ke hana me kēlā me kēia ʻano wai, ʻelua conductive a me ka non-conductive.ʻO ke kumu o ia sensor kahi lana o kahi hoʻolālā kūikawā e pili ana i kahi hui pili.Aia ka sensor ma ka palena palena e hiki ai i ka wai ke hiki i ka wā o ka hana maʻamau o ka ʻōnaehana, a i ka wā e hiki ai ka wai i kēia pae, hoʻouna ia i kahi hōʻailona i ka mea hōʻailona a i ʻole actuator.
ʻElua ʻano nui o nā mea ʻike lele:
● Me kahi lana i hoʻopili ʻia i ka pilina hoʻoneʻe o ka hui hui;
● Me ka lana mākēneki a me ka hoʻololi ʻohe.
ʻO ka DGS o ka ʻano mua ka mea maʻalahi loa i ka hoʻolālā ʻana: ua hoʻokumu ʻia lākou ma kahi lana i ke ʻano o ka ʻimi palaki a i ʻole ka pahu keleawe puka i hoʻopili ʻia i ka pilina hoʻoneʻe o ka hui hoʻopili.Ke piʻi ke kiʻekiʻe o ka wai, piʻi ka lana a i kekahi manawa aia kahi pōkole pōkole a i ʻole, wehe ʻia nā pilina.
ʻO nā sensor o ka ʻano ʻelua he hoʻolālā paʻakikī: ua hoʻokumu ʻia lākou ma kahi koʻokoʻo hollow me kahi hoʻololi o ka ʻohe (magnetic switch) i loko, ma ke axis kahi e neʻe ai kahi annular float me kahi magnet mau loa.ʻO ka hoʻololi ʻana i ka pae wai e neʻe ai ka lana ma ke koʻi, a i ka wā e hele ai ka magnet ma ke kua o ka ʻohe, ua pani ʻia a wehe ʻia kona mau pilina.
E like me ke ʻano o ke kaiapuni hana, ua māhele ʻia nā sensor automotive-hydraulic alarm i ʻehā mau ʻano nui:
● No ka hana ma ka wai;
● No ka hana i ka antifreeze;
● No ka hana ma ka aila;
● No ka hana ʻana i ka wahie (gasoline a i ʻole diesel).
ʻO ka mea ʻike kiʻekiʻe-hydraulic me kahi ʻimi metala
Kiʻikuhi o ka mea ʻike lana me ka hoʻopili ʻana

ʻOkoʻa ka DGS no nā pāpaʻi like ʻole i nā mea i hoʻohana ʻia, a ʻokoʻa hoʻi nā mea ʻike lana i ka nui o nā lana e hāʻawi i ka hāpai ʻana i nā kaiapuni o nā ʻano like ʻole.
E like me ke kūlana maʻamau o nā pilina, ua māhele ʻia nā sensor i ʻelua pūʻulu:
● Me nā mea hoʻopili maʻamau;
● Me nā pilina paʻa mau.
Hiki i nā mea ʻike ke loaʻa nā ʻano like ʻole o ka hoʻopili ʻana i ka ʻōnaehana uila: nā mea hoʻopili mamao me nā pili pahi, nā mea hoʻohui i hoʻohui ʻia me nā pili pahi a me nā mea hoʻohui ʻano bayonet-type.ʻO ka maʻamau, ʻehā mau pine DGS kaʻa: ʻelua no ka lako mana ("plus" a me "minus"), hoʻokahi hōʻailona a hoʻokahi calibration.
ʻO nā hiʻohiʻona nui o nā mea ʻike, pono ia e hōʻike i ka uila hāʻawi (12 a i ʻole 24 V), ka manawa lohi o ka pane (mai ka hana koke a hiki i kahi lohi o kekahi mau kekona), ka pae wela o ka hana, ka hoʻohana ʻana i kēia manawa, ka ka pae kau a me ka nui o ka turnkey hexagon.
ʻO ka hoʻolālā a me nā hiʻohiʻona o nā mea ʻike automotive-hydraulic signaling device
Ua like ka hoʻolālā like ʻana o nā DGS kaʻa o kēia wā.Hoʻokumu ʻia lākou ma kahi pahu keleawe, aia ma waho o kahi kaula a me kahi hexagon turnkey.Aia i loko o ka hihia kahi mea sensing (float probe a i ʻole steel probe), kahi hui pili a me kahi papa me ka amplifier / generator circuit.Aia ma luna o ka mea ʻike he mea hoʻopili uila a i ʻole kahi kaula uwea me kahi mea hoʻopili ma ka hope.
Hoʻokomo ʻia ka sensor i loko o kahi pahu a i ʻole nā mea ʻē aʻe o ka ʻōnaehana hydraulic e hoʻohana ana i kahi kaula ma o kahi O-ring (gasket).Me ke kōkua o kahi mea hoʻohui, pili ka ʻike i ka ʻōnaehana uila o ke kaʻa.
Hiki i kahi kaʻa ke loaʻa i ʻelima a ʻoi aʻe paha nā sensor-hydraulic alarms e hana i nā hana o ka nānā ʻana i ke kiʻekiʻe o ka wahie, coolant, aila i loko o ka ʻenekini, wai i ka ʻōnaehana hydraulic, wai i ka mana hoʻokele, etc.
Pehea e koho ai a hoʻololi i ka alarm sensor-hydraulic
Nā mea ʻike pae waihe mea nui no ka hana maʻamau o nā ʻōnaehana pākahi a me ke kaʻa holoʻokoʻa.Hōʻike nā hōʻailona like ʻole i ka haki ʻana o ka DGS - nā hōʻailona wahaheʻe o nā mea hōʻailona a i ʻole nā mea hana (e hoʻohuli a hoʻopau paha i nā pamu, a me nā mea ʻē aʻe), a i ʻole, ʻaʻole i loaʻa kahi hōʻailona ma ka hōʻailona a i ʻole nā mea hana.I mea e pale aku ai i nā hewa koʻikoʻi, pono e hoʻololi koke ʻia ka sensor i ka hiki.
No ka hoʻololi ʻana, pono e lawe i nā sensor wale nō o kēlā mau ʻano a me nā hiʻohiʻona i ʻōlelo ʻia e ka mea hana kaʻa.Pono ka DGS i kekahi mau ana a me nā hiʻohiʻona uila, i ka wā e hoʻokomo ai i kahi sensor o kekahi ʻano ʻē aʻe, hiki ke hana hewa ka ʻōnaehana.Hoʻololi ʻia ka sensor e like me nā ʻōlelo aʻoaʻo hoʻoponopono o ke kaʻa.ʻO ka mea maʻamau, hele mai kēia hana i ka hoʻopau ʻana i ka sensor, hoʻohuli iā ia me kahi kī, a hoʻokomo i kahi mea ʻike hou.E hoʻomaʻemaʻe i ka wahi hoʻokomo o ka sensor mai ka lepo, a hoʻohana i kahi O-ring (i hoʻokomo pinepine ʻia) i ka wā e hoʻokomo ai.I kekahi mau hihia, pono paha e hoʻokahe i ka wai mai ka mīkini.
Nā mea ʻike-hydraulic alarms
Ma hope o ka hoʻouka ʻana, pono kekahi mau sensor i ka calibration, ke kaʻina hana i wehewehe ʻia i nā ʻōlelo kuhikuhi pili.
Me ke koho pololei a me ka pani ʻana o ka sensor-hydraulic alarm, e hana maʻamau nā ʻōnaehana e pili ana me ia, e hōʻoiaʻiʻo ana i ka hana pono a me ka palekana o ke kaʻa.
