He kaiwhakarato taputapu hanga mō ngā mīhini hanga mō ngā tau 30.
Ahakoa kāore te mata taimana e tapahi ana, ehara i te mea kua oti katoa ngā wāhanga taimana. Ahakoa kei te tū tonu te wāhanga ki runga ake i te pūtake maitai, ka puta he puehu i te mata, ka ngaro te tere tapahi, ā, ka uaua ki te tomo ki te raima. I te nuinga o te wā, ko te raruraru ko te whakakanapa o te mata taimana , ka puta ina kore e tere te pakaru o te here whakarewa hei whakaatu i ngā taimana hou.
Ko te karaihe tētahi o ngā take pea. Ka taea hoki e te mata kani raima te tohu i te iti o te mana o te miihini, te wetewete o ngā whitiki taraiwa, te RPM hē, te rere kino o te wai, te pakaru rānei o te mata. Tērā pea ka rite ngā tohu mai i muri o te kani, nō reira ko te huarahi tika ko te tirotiro i te mata, te mīhini me ngā āhuatanga tapahi kia mārama te raupapa. Mā te pana kaha ake ka tāpirihia he wera, ehara i te mōhio.
| Ngā mea e kite ana koe | Te take pea | Tirohanga tuatahi |
|---|---|---|
| He mata wāhanga maeneene, kanapa rānei | Te karaihe, te hononga rānei he mārō rawa | Ngā whakaritenga o te mata me te āhua o te rauemi |
| Ka mau tonu te teitei o te wāhanga, engari ka puhoi te tapahi | Kāore ngā taimana hou e whakaatuhia ana | Mēnā ka whakahokia mai te motu e te kakahu haumaru |
| Ka heke te tere o te miihini i raro i te kawenga | Te pēhanga whāngai nui rawa, te mana iti, ngā whitiki wetekina rānei | Āhua o te miihini, te kukū o te whitiki me te pēhanga tapahi |
| Ka memeha te tae o te matua o te mata | Te wera rawa, te ngoikore rānei o te whakamatao | Te tuku wai, te huringa tapahi maroke me te whakatauranga o te mata |
| Ka pakaru te matua rino i raro i ngā wāhanga | Te tapahi i raro i te rauemi whakakoi | Momo rauemi me te parenga tapahi iti |
| Ngā kapiti, ngā wāhanga ngaro, te uho piko rānei | Te pakaru o te mata o te hanganga | Whakamutua te kani, ka whakakapia te mata |
Kei roto i tētahi wāhanga taimana ngā taimana hangai e mau ana i roto i tētahi here whakarewa. I te wā tapahi noa, ka hurihia e ngā taimana te rauemi i te mea ka memeha haere te here e karapoti ana. Ka tukuna ngā taimana mangu, ā, ka puta mai ngā pūwāhi tapahi hou ki te mata o te wāhanga.
Ka tīmata te whakakanapa ina mutu te mahi tika o tēnei kakahu kua whakahaeretia. Ka noho piri tonu te hononga ki ngā taimana kua tawhito, ka waiho he mata maeneene me te iti o te taimana hou e kitea ana. E ai ki ngā kōrero. He aratohu mō te rapurongoā mō te mata taimana a Norton , he mārō rawa te mata mō te rauemi, tērā pea kāore e whakaatu i ngā taimana hou. E taunaki ana a Norton kia neke ki tētahi hononga ngohengohe ake ina hiahiatia he whakakakahu anō.
He mea nui tēnei rerekētanga nā te mea ka taea e te whakakakahu te whakatuwhera anō i te mata karaihe, engari kāore e taea te whakatika tuturu i te whakatakotoranga hē o te mata. Mēnā ka kati anō te mata i muri i te wā poto o te tapahi, tera pea kāore i te ōrite te rauemi me te hononga.
Kāore pea te kirikiri mārō, kāore e tino whakakoi, e tere te mau o te here kāore e tika ana. He maha ngā wā ka tīmata pai te mata, kātahi ka pōturi ake te tapahi i te mea ka orohia te mata o te wāhanga. Mā te pēhanga whāngai nui ake ka kaha ake te mahi a te mīhini, engari kāore e āwhina i te here ki te tuku i ngā taimana mangu.
Ina hoki mai te karaihe i muri i te whakakakahu, ā, kei te tika te mahi a te kani, ko te huri ki tētahi hononga ngohengohe te huarahi hangarau tika. Mō ngā kaupapa e pā ana ki te raima me te uku, me whakaū tuatahi kei te ōrite te mata ki te rauemi, kaua e tono kia rite te mahi a tētahi whakatakotoranga ki ngā mata e rua.
Ka raru tonu pea te mata o te kani i whiriwhiria tika ina kore te kani e mau tonu te tere i raro i te kawenga. E tohutohu ana a Norton ki ngā kaiwhakahaere kia tirohia te hōpaea me te āhua o te whitiki taraiwa ina kore te mata e tapahi. Ka taea e ngā whitiki wetekina, te miihini e oma kino ana, me te tere whāngai kaha te whakaiti i te tere o te mata o te kani i te mata tapahi.
Whakarongo ki te mīhini i te tīmatanga o te tapahi o te mata. He mea noa te paku rerekētanga o te oro, engari ko te hekenga tere o te tere e tohu ana he nui rawa te tere whāngai, kāore rānei te mana e tae pai ana ki te mata. I mua i te whakapae i ngā taimana, me whakarite kei te mahi te mīhini, ngā whitiki me te kakau o te mata i tā rātou mahi.
Me tirotirohia te RPM o te mata me te whānui o te mata. Te aratohu tapahi raima a MK Diamond E taunaki ana kia tata ki te 9,500–11,500 putu mata ia meneti te tere whakahaere o te awhi mō te nuinga o ngā mata taimana. Ko ngā tere iti ake ka whakamahia mō ngā rauemi pakeke ake, kikī ake, ko ngā tere teitei ake ia ka pai mō ngā rauemi ngawari ake, he koi ake.
E whakaatu ana te ripanga tere kua whakaputaina he aha te hiranga o te whānui. Ko te tere tohutoro o te mata 12-inihi paerewa he 3,000 rpm, ko te mata 14-inihi he 2,500 rpm, ā, ko te mata 20-inihi he 1,800 rpm. He uara tohutoro MK ēnei, ehara i te tautuhinga whānui, engari e whakaatu mārama ana kāore e taea te tāuta haumaru i tētahi mata nui ake mā te tirotiro anake i te kōhao arbor.
| Te whānui o te mata | RPM tohutoro MK | Kāore rawa a MK e neke ake i te RPM |
|---|---|---|
| 12 inihi / 305 mm | 3,000 rpm | 5,095 rpm |
| 14 inihi / 356 mm | 2,500 rpm | 4,365 rpm |
| 16 inihi / 406 mm | 2,200 rpm | 3,800 rpm |
| 20 inihi / 508 mm | 1,800 rpm | 3,000 rpm |
Me whai tonu i te RPM mōrahi kua tāia ki te mata kua tīpakohia me te awhe tere kua whakaaetia o te kani. Tērā pea ka uru pai te mata engari kei te hurihuri tonu i te tere hē, koinei te putanga ā-ringa o te mau i ngā pūtu rahi tika i runga i ngā waewae hē.
Mō te tapahi mākū, me tae te wai ki ngā taha e rua o te mata, ā, me horoi te paru whakakoi i roto i te kerf. E homai ana e MK Diamond he tohutoro a te kaihanga mō te 4.5–6 karani US ia meneti , he rite ki te 17–23 rita ia meneti . Ko te whakaritenga whakamutunga e whakawhirinaki ana ki te kani, te mata me te mahi horoi o te tapahi, nō reira ko te pukapuka ā-taputapu te tohutoro whakahaere.
Kāore te ārai mata makuku e whakaatu ana kei te nui te wai e tae atu ana ki ngā wāhanga. Tirohia ngā pūwero e rua mō ngā aukati, me te mātakitaki mēnā ka puta noa te paru i te tapahi. Mā te tohatoha wai ngoikore ka nui ake te wera, ka whakaiti i te pai o te tapahi, ka kore e ōrite te pakaru o te taha.
Mō ngā mata kua whakaaetia kia maroke, E kī ana a Norton kia kaua e tapahia roa, haere tonu ā, e taunaki ana kia tukuna te mata kia hurihuri i te hau i ia meneti torutoru. Tērā pea me whakamatao pinepine ake ngā rauemi pakeke. Kāore he ture whānui mō te toru meneti, te rima meneti rānei, nō reira me whai i ngā tohutohu a te kaihanga mata.
Ehara i te pāmahana o te mata anake te pānga o te tuku wai. Paerewa hanga silica OSHA o Amerika , ko te taumata mahi mō te silica tioata ka taea te manawa ko te 25 μg/m³ , ko te rohe whakaaturanga e whakaaetia ana ko te 50 μg/m³ . Ka tatauhia ngā mea e rua hei toharite taumaha-wā e waru hāora.
E hiahiatia ana e te Ripanga 1 o te OSHA kia whakamahia e ngā kani hikoi-muri tētahi pūnaha whakauru e whāngai tonu ana i te wai ki te mata. Kāore e hiahiatia he manawa tāpiri mō ngā mahi o waho e whakamahi ana i te tikanga whakahaere kua whakarārangihia, engari ko ngā mahi o roto, o roto rānei, me whai i te iti rawa he tiaki manawa APF 10. Koinei ngā whakaritenga a te US; me whai ngā kaimahi kirimana i ētahi atu whenua i ngā ture o te mana whakahaere kaupapa.
| Taonga OSHA | Whakaritenga kua whakaputaina |
|---|---|
| Taumata mahi silica | 25 μg/m³ i roto i te TWA 8-hāora |
| Te rohenga whakaaturanga e whakaaetia ana | 50 μg/m³ i roto i te TWA 8-hāora |
| Mana whakahaere kani hikoi-muri | Te tuku wai whakauru tonu |
| Te whakamahinga o roto, o roto rānei | APF iti rawa 10 |
Kati te kani, ka tirotirohia te mata i mua i te ngana ki te whakapaipai. He pai te whakapaipai ina he pakari te hanganga o te mata, ā, kua kati, kua orohia rānei te mata o te wāhanga. Kaua e whakapaipai i te mata he ngatata, he wāhanga ngaro, he uho piko, he ngoikore rānei kei raro i ngā wāhanga.
Whakaūtia kei te tika te whakatauranga o te mata mō te rauemi, te kani me te tikanga mākū, maroke rānei.
Tirohia te pere hurihuri, te arbor, ngā flange, ngā whitiki me te pūnaha wai.
Whakamahia he rauemi whakakakahu kua whakaaetia e te kaihanga, he poraka ngohengohe rānei hei whakakoi.
Hangaia he tapahi poto, kātahi ka mutu ka tirotiro i te mata o te wāhanga.
Hoki atu ki te rauemi mahi mā te whakamahi i te pēhanga whāngai taurite.
E whakarārangihia ana e Norton he poraka raima ngohengohe, he wira tawhito rānei hei rauemi whakakī. Mena ka pai ake te tapahi mō te wā poto engari ka hoki mai te karaihe, hurihia te whakatakotoranga here, kaua e huri i te whakakī hei mahi whakangahau o ia rā.
| Āhua | Āhua noa | Mahi i tūtohutia |
|---|---|---|
| Te whakakanapa | Mata wāhanga maeneene me te teitei e toe ana | Tirohia te ōritetanga o te here me te kakahu mēnā he pai te hanganga |
| Te kakahu noa | Ka whakaitihia ngā wāhanga kia ōrite, ā, ka mau tonu te tapahi | Me haere tonu ngā tirotiro me te whakakapi i te rohe kua tohua |
| Te tapahi i raro i te mana | Ka angiangi haere te maitai i raro tonu i ngā wāhanga | Kati mēnā ka ngoikore; whakamahia he mata he ārai tapahi raro |
| Ngā pakaru hanganga | Ngā kapiti, ngā wāhanga ngaro, te uho piko rānei | Whakakapia tonutia |
Ka taea e te poraka whakapaipai te whakaatu i ngā taimana hou, engari kāore e taea te whakatika i te matua maitai pakaru. Mēnā kua pakaru te hanganga o te mata, ko te whakakapi anake te huarahi pai.
I mua i te tono i tētahi mata hou, tuhia te rauemi, te āhua o te rauemi, ngā whakatakotoranga o te mata, te tauira kani, te whānui o te mata, te RPM mōrahi, te hohonutanga tapahi me te tikanga mākū, maroke rānei. Kātahi ka tirohia te kukū o te whitiki, te tere o te miihini, ngā whāriki o te rakau, te āhua o te flange me te tuku wai.
He mea whakatapua kani raima hikoi-muri me whakahaere me te mata e ōrite ana ki te rauemi me te mīhini. Mō te tapahi rori hohonu ake, whakatairitehia hoki te rahi o te mata kua whakaaetia me te hohonu o te tapahi o te mīhini kua tīpakohia, pērā i te Kani rori raima ACE QF400 .
Ko te mata o te mata karaihe he mata maeneene, he teitei wāhanga e toe ana, ā, he mārama te ngaronga o te tere tapahi. Me whakaū kei te mau tonu te mana o te mīhini i mua i te whakakakahu i te mata.
He maha ngā wā ka taea te whakakakahu i tētahi mata karaihe kāore anō kia pakaru kia kitea ai ngā taimana hou. Me whakakapi tētahi mata kua pakaru, kua piko, kua pakaru rānei.
Ko te whakakākano anō i te mata he tohu i te hononga e mārō rawa ana mō te rauemi, te iti o te kaha kani, te nui rawa rānei o te pēhanga whāngai. Tirohia anō te whakatakotoranga o te mata me te āhua o te mīhini.
E whakarato ana a MK Diamond i te tohutoro mō te 4.5–6 US gal/min, ara 17–23 L/min. Me whai te rere whakamutunga i ngā tohutohu a te kaihanga kani me te mata.
Whakakapia ina tae te paparanga taimana e taea ana te whakamahi ki tōna taumata kua tohua, ina ngaro tētahi wāhanga, ina pakaru, ina piko rānei te uho, ina ngoikore rānei te maitai i raro i ngā wāhanga nā te tapahi iti.
Aratohu Uiui mō ngā Hua Taiao:
Tohaina te rauemi, te āhua o te rauemi me ngā whakatakotoranga o te mata ina tono tautoko rapurongoā.
Whakaurua te tauira kani, te whānui o te mata, te rahi o te rākau, te RPM mōrahi me te mea he mākū, he maroke rānei te tapahi.
Mā ngā whakaahua o te mata o te wāhanga, te uho maitai me te tauira kakahu ka āwhina i te wehewehe i te karaihe mai i te pakaru o te maitai, te pakaru hanganga rānei.
