Ngā Utauta Mahi-Whakahou | Akomanga Keri-Mira-Mira | Mōta Nekehanga Pai

1. Ngā tono

Mā te pēhanga waipēhi e whakakahangia, ka hurihia te huihuinga keri o raro i te PDM, ka taea ai ngā mahi pēnei i te keri, te mira, me te huri taha.

2. Hanganga

Ko te PDM te nuinga o te wā he wāhanga o runga,takirere taha, te stator, te rotor, te hononga, te raro ara wai, te huihuinga peera, te pou taraiwa, me te raro raro.

3. Te Mātāpono Whakahaere

Ka hurihia e te PDM te pūngao o te wai pēhanga teitei ki te pūngao miihini mā te taunekeneke o te rotor me te stator. Ka uru te wai pēhanga teitei ki roto i ngā rūma hiri i hangaia i waenganui i te rotor me te stator. Mā te rerekētanga pēhanga ka huri te rotor i te awa porowhita o te stator. Ka huri te rotor i te taha o te tuaka o te stator, me te huri huri-matau i runga i tōna ake tuaka, e akiaki ana i te hurihanga o te mata keri.

4. Ngā Whakatakotoranga Hangarau

Paerewa e tika ana: SY/T 5383 Mōta Nekehanga Pai

Tauira whakatakotoranga

ngā tauira:

• 9LZ95×7.0: Te whānui o waho 95 mm, te mōtini waipēhi ōwehenga 9/10 o te pūwero, te maturuturunga pēhanga o te pūwero mata 7 MPa.
• 5LZ165×7.0Ⅱ: Te whānui o waho 165 mm, te ōwehenga o te motuka waipēhi 5/6, te hekenga pēhanga o te pūwero moka 7.0 MPa, te whakarerekētanga hoahoa tuarua o te PDM tinana-tika.
• 5LZ197×7.0-SWFG: Te whānui o waho 197 mm, te mōtini waipēhi ōwehenga 5/6 o te pūwero, te whare piko-rua me te whakau, te rotor tuwhera me te hurihanga rere, te pāmahana mahi mōrahi 150°C, te maturuturunga pēhanga o te pūwero moka 7.0 MPa.

5. Te Tukanga Whakahaere

(1) Huihuia te BHA.

(2) Oma āta ki te 3–5 m i runga ake i te hohonutanga e hiahiatia ana, tīmatahia ngā papu hei hurihanga me te horoi i te puna. E taunakihia ana kia 30 m/min te tere oma. Whakakīia te aho keri ki te wai hurihanga ma i ia 500 m o te oma.

(3) Whakaheke mārire, kātahi ka tīmata te keri. Taumaha i runga i te mata (WOB): 5–15 kN. Tere rere: 500–600 L/min.

(4) Tōia mai i te kōhao (POOH).

6. Ngā Whakatūpato

(1) Me whakarite kia mau te PDM mata i te wā e whakamātautau ana i te mata.

(2) Me ma te wai tohanga toto.

(3) Me tātari te wai whakahoki, ā, me tango te kirikiri.

(4) Me whai taputapu hiri-ā-unoa te pane o te puna hei ārai i ngā mea ririki kei taka ki roto i te puna.

(5) Horoia pai ngā poka i mua i te whakawhiti i ngā takirua, ā, i muri i te otinga o te keri.

7. Te Tiaki me te Rokiroki

(1) I muri i te whakamahinga, wetewetehia, horoia, ā, tirohia te taputapu. Whakakapia ngā wāhanga kua pakaru. Pania he hinu whakahinuhinu ki ngā wāhanga katoa i te wā e huihui ana anō.

(2) Kaua e whakamahia te mamaoa i te wā e horoi ana i te arai rapa stator hei ārai i te koroheketanga o te rapa.

(3) Rokirokihia te taputapu ki roto i tētahi whare putunga e pai ana te hau. Kia mau tonu te pāmahana i waenga i te 10°C me te 25°C, kaua hoki e neke ake i te 85% te haumākū. Āraia te rā tika me te ua.
