ʻIke ʻia ke kumu o ka haʻalulu kaʻa

Wahi a kakaʻa uilaʻO ka mea hana, aia nā ʻāpana uila a me nā mīkini i ke ʻano o ka mīkini, no laila e nānā ʻia kona mau hewa i ʻelua ʻāpana.

Ma ka ʻōlelo maʻamau, hoʻokumu ʻia ka haʻalulu kaʻa ma muli o ke kaulike ʻole o nā ʻāpana wili, ka hemahema mechanical a i ʻole nā ​​kumu electromagnetic.

1, ʻo ka ʻāpana ʻōwili o ka imbalance ma muli o ka rotor, coupler, coupling, transmission wheel imbalance.

ʻO ke ala e hana ai i kēia, ʻo ia ka ʻimi ʻana i ka sub-equilibrium ma luna. wehe.

2. ʻO nā hemahema o ka mīkini ka nui o kēia mau mea:

1) ʻAʻole pololei ka ʻāpana pili o ka shafting, ʻaʻole kūlike ka laina waena, a ʻaʻole pololei ke kikowaena.

ʻO ke kumu nui o kēia ʻano hewa ʻo ia ke kaʻina hana, ma luna o ka poʻe ʻilihune, hoʻokomo pono ʻole.

Aia kekahi hihia ʻē aʻe, ʻo ia hoʻi, ua kūlike kekahi ʻāpana linkage o ka laina waena i ke kūlana anuanu, akā ma hope o ka holo ʻana no kekahi manawa ma muli o ka fulcrum rotor, deformation kumu, ua luku ʻia ka laina waena, a pēlā e hana ai i ka haʻalulu.

2) aia kekahi mea hewa i ke kaʻa a me ka hoʻohui ʻana i pili me ke kaʻa. ʻO kēia hewa ke hōʻike nui ʻia e like me ke ʻano o ka nahu ʻino, ka niho niho koʻikoʻi, ka lubrication maikaʻi ʻole o ka huila, ka pili ʻana o ka huila, ka dislocation, ka hoʻopili ʻana i nā niho niho, ka mamao o ka niho. hewa, ʻoi aku ka nui o ka hoʻomaʻemaʻe ʻana a i ʻole ka ʻaʻahu koʻikoʻi, e hoʻoulu i kekahi haʻalulu.

3) nā hemahema o ke kūkulu ʻana a me nā pilikia hoʻokomo o ka kaʻa ponoʻī.

Hōʻike nui ʻia kēia hewa ma ke ʻano he ellipse o ka ʻāʻī o ka ʻāʻī, ke kulou ʻana o ke kumu, ka nui a i ʻole ka liʻiliʻi liʻiliʻi ma waena o ka lāʻau a me ka lāʻau, ʻaʻole lawa ka ʻoʻoleʻa o ka noho ʻana, ka pā kumu, kekahi ʻāpana o ke kumu a me ke kumu hoʻonohonoho holoʻokoʻa holoʻokoʻa, hoʻopaʻa paʻa ma waena o kaʻa a me ka pā kumu, ka ʻūhā o ka wāwae lalo, wehe ma waena o ka noho ʻana a me ka pā kumu, etc.

Akā, ma waena o ka lāʻau a me ka hoʻomaʻemaʻe o ka nahele he nui a liʻiliʻi paha ʻaʻole hiki ke hoʻoulu wale i ka haʻalulu akā hiki ke kumu i ka lubrication o ka nahele a me ka wela e hana i ka mea ʻino.

4) ʻo ka ukana i alakaʻi ʻia e ke kaʻa e hana i ka haʻalulu.

3, ʻo ka hapa o ka pau ʻole o ka uila ke kumu e nā kumu electromagnetic ka mea nui: ac motor stator connection error, asynchronous motor rotor winding short circuit, synchronous motor excitation winding interturn short circuit, synchronous motor excitation coil connection error, cage asynchronous motor rotor broken bar , Rotor core deformation ma muli o uneven air gap, rotor, alakaʻi i ka ea flux imbalance ma muli o ka vibration.
