Poino Mechanical I na Mea Hana Diesel

ʻAʻole pilikia ka mīkini hana hoʻonohonoho e hana ana i ka mana mīkini hana hana iho.Akā ʻelua mau ʻōlelo hōʻoia:

1. I kēia manawa, lilo ka generator i kaʻa, e hoʻomoʻa i ka mana ikaika mai ka ʻōnaehana e mālama i ka hana synchronous, a ʻaʻole loli ka ʻōnaehana hoʻonāukiuki;Eia naʻe, hiki ke emi ka alapine pūnaewele.I ka manawa like i ka mana reactive i ka mānoanoa, ʻaʻole ia e hoʻohaʻahaʻa i ka ʻōnaehana uila, e lilo wale ka hana dimmer.

2. Ma keʻano he turbogenerator, ua pani ʻia ke kīpē nui o ka turbine i ka wā e lilo ai ia i ke kūlana hana maʻamau o ka mana hoʻohuli, a ua wela ka huelo o ka turbine ma muli o ka friction me ke koena mahu.ʻO nā pōʻino i nā turbine mahu.Ma muli o nā kumu ʻelua i luna, ʻo ka pōʻino i ka turbine mahu ka mea nui.No laila, pono e hoʻolako ʻia nā ʻāpana nui me ka pale o ka mana.Mālama kēia pale i nā turbine mahu.

ʻO ke kūpaʻa ʻana o ka mea hoʻomohala, ʻo ia hoʻi ke ana ʻana i ke kūpaʻa insulation stator, ke ana ʻana i ke kūpaʻa insulation rotor, ke ana ʻana i ka pale ʻana i ka insulation, nā mea hana i pili me ka mīkini hana a me ka exciter excitation loop, etc.

Ana ana no ka insulation kū'ē o ka generator

Hoʻohana ʻia e nānā inā he pulu, lepo, ʻino mechanical a me nā pilikia ʻē aʻe.

1. Ke ana kū'ē kū'ē i ka stator.

Hōʻike ʻia ka uea ana ma ke Kiʻi 1. No nā kaʻa i helu ʻia ma mua o 1000 volts, e hoʻohana i ka 2500 volt megohmmeter e ana i ke kūpaʻa insulation no 15 a me 60 kekona a helu i nā helu absorption.Inā liʻiliʻi loa ka pale ʻana a i ʻole ka absorption rate, e hoʻohui i kahi ana kūʻē ʻana no 10 mau minuke e helu ai i ka index polarization.No ka epoxy mica powder insulation, ʻaʻole e emi ka helu absorption ma mua o 1.6, ʻaʻole pono e emi ka helu polarization ma lalo o 1.6.

2.Measuring insulation kū'ē o ka hali hale.

Ke kumu o ke ana ʻana: ʻO nā bearings ma ka ʻaoʻao exciter ka mea maʻamau i hoʻokaʻawale ʻia mai ka lepo i mea e pale ai i ke ʻano ma waena o ka volta shaft a me ka bearing mai ke ahi ʻana i ka pahu ma muli o ka asymmetric flux o ka generator.

Hōʻike ʻia ke ʻano hana insulation bearings maʻamau o kahi turbogenerator ma FIG.4. I ka nānā 'ana i ka insulation o ka bearing, e hoohana i ka 1000V megohmmeter e ana i ka insulation kū'ē o ka metala gasket i ka lepo. Kekahi turbogenerators hoʻohana bushing insulation, kela bushing alakai i ke ana helu, no laila e nānā i ka insulation kū'ē o kela bushing.ʻAʻole loaʻa i kekahi mau turbogenerators nā kumu ana o ka nahele a hiki ke nānā ʻia i ka wā o ka hoʻokomo ʻana.

He mau pad insulation ka pahu a me ke alakai o ka hydro-generator ma lalo o kēlā me kēia pahu pahu.Pono e nānā ʻia ke kū ʻana o ka insulation o kēlā me kēia pad i ka wā e hoʻokomo ai.Ma mua o ka lawe ʻana i ka aila, ʻaʻole pono e emi iho ka pale insulation o kēlā me kēia lāʻau i lalo o 100 mω.

Ke kūpono ʻole ka insulation o ka bearing, ma waho aʻe o ka nānā ʻana i ka pad insulation, pono e uku ʻia i ka nānā ʻana inā he mea maʻamau ka insulation o nā ʻāpana e pili ana i ka bearing, e like me ka mahana, vibration sensor, pipe oil, etc. .

ʻO Guangxi Dingbo Power Equipment Manufacturing Co., Ltd. i hoʻokumu ʻia i ka makahiki 2006, he mea hana i ka mīkini hana diesel ma Kina, ka mea i hoʻohui i ka hoʻolālā, hoʻolako, hoʻokō a mālama ʻana i ka set generator diesel.Uhi nā huahana Cummins, Perkins, Volvo, Yuchai, Shangchai, Deutz, Ricardo , MTU, Weichai etc. me ka mana mana 20kw-3000kw, a lilo i kā lākou OEM hale hana a me ka ʻenehana kikowaena.
