- He aha nā ʻāpana helu o ka waiwai haʻalulu kaʻa? Pehea e hoʻomaopopo ai i kēia mau ʻāpana?
ʻO nā ʻāpana ana maʻamau o ka waiwai haʻalulu kaʻa ka waiwai wikiwiki (i kapa ʻia ʻo ka wikiwiki), ka waiwai amplitude vibration (i ʻōlelo ʻia he amplitude, māhele ʻia i hoʻokahi amplitude a me pālua amplitude) a me ka vibration acceleration. Hoʻohana nui ʻia ka mea mua.
Hiki ke hoʻomaopopo wale ʻia ka "waiwai kūpono o ka wikiwiki" e like me ka mamao i neʻe ʻia e ka mea haʻalulu (hiki ke manaʻo ʻia he kiko) i ka manawa hui. ʻO W ka lōʻihi e koli maoli ai ka mea haʻalulu ma kahi hoʻokahi a neʻe ʻole i nā wahi ʻē aʻe. No laila, ʻo ka mea i kapa ʻia ʻo "moved distance" he ʻano wehewehe wale nō, no laila ua hoʻohana ʻia nā huaʻōlelo "kūpono" a i ʻole "kulike" e wehewehe hou aku ai. Hiki ke noʻonoʻo e pili ana ka waiwai o ka wikiwiki vibration i ka mamao o ka vibration amplitude (ka mamao mai ke kikowaena waena) o ka vibration point. Eia kekahi, pili ia i ke alapine o ka haʻalulu (ka helu o nā kowali i hope a i waho i ka manawa hui) a ua kūlike lākou; hoʻohana ʻia ʻo mm/s ma ke ʻano he ʻāpana.
ʻO ke kiko haʻalulu he ʻāpana e koli i hope a i mua i ʻelua ʻaoʻao. I ka wā e koli ai, ua kapa ʻia ka mamao loa mai ke kūlana waena ʻo ka amplitude. ʻO ka mamao loa ma ka ʻaoʻao hoʻokahi ua kapa ʻia ʻo ka amplitude hoʻokahi, a ʻo ka mamao ma waena o nā wahi mamao loa ma nā ʻaoʻao ʻelua ua kapa ʻia ʻo ka amplitude pālua - maʻamau i ka mm a i ʻole μm.
ʻO ka wikiwiki o ka haʻalulu ka piʻi ʻana o ka wikiwiki i kēlā me kēia manawa M, maʻamau i ka m/s2.
- ʻO wai o nā waiwai ʻelua o ka waiwai wikiwiki a me ka amplitude o ka waiwai vibration ʻoi aku ka maikaʻi? Aia kekahi pilina hoʻololi ma waena o lākou?
E like me ka mea i ʻōlelo ʻia ma luna, hōʻike ka nui o ka amplitude i ka nui o ka amplitude swing, ʻoiai ʻo ka wikiwiki kūpono e hōʻike ana i ka nui o ka amplitude swing a me ka wikiwiki o ke kowali. ʻO ke kiʻekiʻe o ka pōʻino i hana ʻia e ka haʻalulu i ke kaʻa ponoʻī a me nā mea pili e pili ana i ka amplitude a me ke alapine (ka wikiwiki o ka swing). No laila, ʻoi aku ka pahuhopu a ʻoi aku ka waiwai o ka hoʻohana ʻana i ka wikiwiki vibration e loiloi i ka nui o ka waiwai vibration o kahi kaʻa. ʻO kēia ke kumu e hoʻohana pinepine ʻia ai ka waiwai wikiwiki e like me ke ana ʻana o ka vibration i nā kūlana pili honua a me ka home.
No ka mea, ʻaʻole i like like nā kūlana no ka hoʻokumu ʻana i nā nui ʻelua o ka wikiwiki a me ka amplitude, ʻoi aku ka nui o ka wikiwiki o ka vibration ma mua o ka amplitude. No ka holo kaʻa induction,ʻAʻole hoʻokahi ka alapine vibration, a i kekahi manawa he paʻakikī loa ia, me nā alapine kiʻekiʻe ʻelua i hana ʻia e nā electo-magnetics a me nā alapine waena a me nā haʻahaʻa i hana ʻia e nā mīkini.
No laila, ʻaʻohe pilina hoʻololi paʻa ma waena o nā mea ʻelua, akā ma ka ʻōlelo maʻamau, i ka nui o ka amplitude, e hoʻonui pū ʻia ka wikiwiki vibration.
- ʻO nā kumu paha no ka haʻalulu nui o ka kaʻa:
(1) He maikaʻi ʻole nā bearings i kūʻai ʻia a ʻaʻole kūpono i nā kūlana maikaʻi. ʻAʻole hana ʻia ka hui e like me nā koi o ke kaʻina hana, e hoʻoneʻe ana i ka deformation ma muli o ka hopena. ʻO ka ʻae ʻana o ke keʻena halihali o ka uhi hope kaʻa ʻaʻole kūpono, paʻa loa a hemo paha. I kēia manawa, ʻo ke ala maʻalahi ka hoʻohana ʻana i ka hāmare e kīkē mālie ma ke koʻi e ʻike inā loaʻa kahi hoʻomaikaʻi.
(2) Ma muli o ke kū kiʻekiʻe o ka uhi ʻana a i ʻole ka paʻakikī o ka pūnāwai nalu, ua paʻa nā bearings ma nā ʻaoʻao ʻelua. I kēia manawa, ka haʻalulu o kaʻekolu ʻāpana asynchronous motorkiʻekiʻe pinepine, a hoʻopuka pinepine ʻia kahi leo "buzzing".
(3) ʻAʻole pololei ke koena ikaika o ka rotor, a ʻaʻole lawa ka pololei.
(4) ʻAʻole kūlike ka ea ea ma waena o ka stator a me ka rotor, a aia kahi hanana sweeping kūloko.
(5) Ua haki ka rotor, a e lele ana ka ukana i kekahi manawa.
(6) Kakaʻa uilaʻAʻole kaulike ka wāwae, a ʻaʻole i hoʻokomo ʻia me ka lako ukana.
