Pūnaha Servo Vicks mō te Mīhini Hanga Werohanga Papu Hinu Servo

Pūnaha Waipēhi Mīhini Whakarewa Werohanga

Hanganga oPūnaha Ratonga Waipēhi

I muri i te whiwhinga o te whakahau pēhanga me te rere mai i te mīhini whakarewa werohanga, ka whakahaerehia te tatau PID me te urupare pēhanga me te tere tuturu hei akiaki i te motuka servo me te papu waipēhi me te wā urupare tere me te tika o te tukurua.

Ngā Āhuatanga o te Pūnaha Pūngao Waipēhi (E rima ngā āhuatanga)

Te whakamahinga mana matua o te mīhini whakarewa werohanga tuku iho

Ina whakamahia he pūnaha waipēhi, neke atu i te 75% o te pūnaha werohanga katoa te kaha e pau ana. E hiahiatia ana ngā pēhanga me ngā rerenga rerekē i te wā o te tukanga, tae atu ki te katinga pokepokea ai, te werohanga, te pēhanga pupuri me te whakatuwheratanga pokepokea ai. Ina nui ake ngā whakaritenga rere me te pēhanga i ngā tautuhinga, ka whakatikatikaina te takirere whakawātea, te takirere taurite rānei, ka hua ake he 40%-75% te nui ake o te kaha e pau ana.

(2)  Otinga mō te Whakararuraru Tohu

Ina tāutahia te puku ki te papatohu whakahaere, ko ngā ārai mō te pokanoa tohu ko:

●  Me wehe motuhake ngā waea o te ara iahiko matua me te ara iahiko whakahaere.

●  Te whakatakoto whenua tika ina hiahiatia

●  Whakamahia te taura ārai mō te ara iahiko whakahaere

●  Whakamahia te waea ārai mō te waea ara iahiko matua

(3)  Me pēhea te whiriwhiri i tētahi puku ratonga ranu me te mōta e tika ana

I ngā whakamahinga tūturu, ka rerekē te kōwhiringa o te puku servo ranu me te motuka nā te rerekētanga o ngā pūnaha hinu.

I ngā tauira e whai ake nei, e whakamahia ana te tere rere o te 64L/min me te pēhanga pupuri mōrahi o te 17.5 Mpa.

●  Te Nekehanga o ngā Papu Waipēhi:whiwhi i te nekehanga o te papu waipēhi (cc/rev) mai i te rere o te pūnaha mōrahi (L/min)

Tauira: Me kī ko te rere mōrahi o te pūnaha he 64L/min, ā, ko te tere mōrahi o te mōtini he 2000rpm. Ko te nekehanga o te papu waipēhi he 64/2000*1000=32cc/rev

●  Te taipana mōrahi o te motuka:tikina te taipana mōrahi mai i te pēhanga mōrahi me te nekehanga o te papu waipēhi

Tauira: Me kī ko te pēhanga mōrahi ko te 17.5 Mpa, ā, ko te nekehanga o te papu waipēhi ko te 32cc/rev. Ko te taipana ko te 17.5*32*1.3/(2p)=116Nm (ko te tauwehe ko te 1.3 hei utu mō ngā mate pūnaha katoa, ā, ka taea te whakarerekē ki te 1.2 ki te 1.3 e hiahiatia ana)

●  Te taipana motuka kua whakatauria me te mana motuka kua whakatauria:Ko te taipana e hiahiatia ana mō te pēhanga pupuri i te pēhanga mōrahi me rua te taipana motuka kua whakatauria, me iti iho rānei (whakamahia ngā raraunga i homai mai i te tipu motuka hei kaupapa matua). Nā te mea ka ngawari te pāmahana o te motuka e whakahaerehia ana i raro i tēnei āhuatanga ki runga ake i te pāmahana. Ki te mea ka whiriwhiria e tātou te rua o te taipana kua whakatauria, ko te kāpata motuka he 9.1kW* me te tere kua whakatauria 1500rpm ina ko te taipana motuka kua whakatauria he 58N-m.

*Tātai Mana Mōta:P(W)=T(Nm)Xw (rpmX2)π/ 60)

  ●Te Auaha Mōrahi o te Mōta:

Ki te whiwhi i te tauwehenga kt (Taipana/A)=3.31 i roto i te whakatakotoranga mō te motuka, ko te iahiko mōrahi he tata ki te 115/3.31=35A ina ko te taipana mōrahi he 116N-m.

●  Tīpakohia te Puku Matau:Kōwhiria te puku tika kia rite ki ngā hiahia o te kiritaki. Me kī ko te kaha o te puku ki te utaina i te taumaha he 150% mō te 60 hēkona, ā, ko te 200% mō te 3 hēkona. Ina tae te pēhanga pupuri ki te 17.5 Mpa me te papu waipēhi 32cc/rev, ko te iahiko e hiahiatia ana e te motuka he 35A.

Kia mōhio mai Mena kāore he mōtini e tika ana, whakamahia te mōtini mana nui ake e whai ake nei.
