ʻO nā pā lei a me ka High Volume Low Speed ​​(HVLS).lawelawe i nā kumu like o ka hāʻawi ʻana i ka ea a me ka hoʻomaha ʻana, akā ʻokoʻa lākou ma ke ʻano o ka nui, hoʻolālā, a me ka hana. Eia kekahi mau ʻokoʻa nui ma waena o nā mea ʻelua:

1. Ka nui a me ka uhi ʻana:

ʻO nā peʻa kepau: ʻO ka nui maʻamau mai 36 a 56 ʻīniha ke anawaena a ua hoʻolālā ʻia no nā wahi noho a i ʻole nā ​​​​wahi pāʻoihana liʻiliʻi. Kau ʻia lākou ma nā kaupaku a hāʻawi i ka ea ea kūloko i kahi palena palena.

Nā mea pā HVLS: ʻOi aku ka nui o ka nui, me nā anawaena mai ka 7 a 24 kapuaʻi. Hoʻolālā ʻia nā mea pā HVLS no nā wahi ʻoihana a me nā ʻoihana me nā kaupaku kiʻekiʻe, e like me nā hale kūʻai, nā hale hana, nā hale haʻuki, a me nā mokulele. Hiki iā lākou ke uhi i kahi wahi ʻoi aku ka nui me kā lākou mau lau nui, maʻamau a hiki i ka 20,000 kapuai kuea no ka pehi.

2.Ka nui o ka neʻe ʻana o ka ea:

ʻO nā mea hoʻolele lewa: E hana me nā wikiwiki kiʻekiʻe a ua hoʻolālā ʻia e hoʻoneʻe i nā leo liʻiliʻi o ka ea i loko o kahi ākea paʻa. Maikaʻi lākou no ka hana ʻana i ka makani mālie a hoʻomaha i nā poʻe ma lalo pono o lākou.

Nā mea pā HVLS: E hana ma nā māmā haʻahaʻa (maʻamau ma waena o 1 a 3 mau mika no kekona) a ua hoʻoikaika ʻia no ka hoʻoneʻe mālie ʻana i nā lewa nui ma kahi ākea. ʻOi maikaʻi lākou i ka hana ʻana i ka lele ʻana o ka ea ma kahi ākea nui, e hāpai ana i ka ea, a me ka pale ʻana i ka stratification wela.

3.Blade Design a me ka hana:

ʻO nā mea pā o ka lei: ʻO ka maʻamau he nui nā lau (maʻa mau ʻekolu a ʻelima) me kahi kihi pitch ʻoi aʻe. Huli lākou i nā māmā kiʻekiʻe e hoʻohua i ka ea.

Nā mea pā HVLS: He ʻuʻuku, ʻoi aku ka nui o nā lau (maʻamau ʻelua a ʻeono) me kahi kihi pitch pāpaʻu. ʻO ka hoʻolālā e hiki ai iā lākou ke hoʻoneʻe maikaʻi i ka ea ma nā haʻahaʻa haʻahaʻa, e hōʻemi ana i ka hoʻohana ʻana i ka ikehu a me nā pae walaʻau.

4. Kauʻana wahi:

ʻO nā pā lei: Kau pololei ʻia ma ke kaupaku a hoʻokomo ʻia i kahi kiʻekiʻe kūpono no ka hale noho a i ʻole nā ​​pā pāʻoihana maʻamau.

Nā mea pā HVLS: Kau ʻia ma nā kaupaku kiʻekiʻe, maʻamau mai 15 a 50 kapuaʻi a ʻoi aʻe paha ma luna o ka honua, e hoʻohana pono i ko lākou anawaena nui a hoʻonui i ka uhi ʻana o ka ea.

5.Application a me ka Environment:

Nā mea pā o ka lei: Hoʻohana mau ʻia i nā hale, nā keʻena, nā wahi kūʻai, a me nā wahi pāʻoihana liʻiliʻi kahi i kaupalena ʻia ke kiʻekiʻe a me ke kiʻekiʻe.

Nā mea pā HVLS: He kūpono no nā wahi ʻoihana nui, kālepa, a me nā keʻena me nā kaupaku kiʻekiʻe, e like me nā hale kūʻai, nā hale hana, nā kikowaena hoʻolaha, nā hale haʻuki, nā mokulele, a me nā hale mahiʻai.

Ma keʻano holoʻokoʻa, ʻoiai nā mea pā kaupaku a meNā mea pā HVLSlawelawe i ke kumu o ka ea a me ka hooluolu, ua hoʻolālā kūikawā ʻia nā mea pā HVLS no nā noi ʻenehana a ua hoʻoikaika ʻia e hoʻoneʻe i ka nui o ka ea ma nā wahi ākea me ka haʻahaʻa o ka ikehu a me ka leo liʻiliʻi.
