1. Whakanuia te pakari

Mō ngā wiri me ngā wiri iti, ka taea te whakanui ake i te pakari hei whakakore, hei whakaiti rānei i tōna pakari. Hei tauira, he mea taea te whakamahi i tētahi puna he pakari nui, he whakamahi rānei i tētahi kaiwhakaoho piston.

2. Whakanuia te whakamākū

Ko te whakanui ake i te whakaiti i te pāmahana he whakanui ake i te waku ki te wiri. Hei tauira, ka taea te hiri i te mono takirere o te takirere ringaringa ki te mowhiti "O", ki te whakakī karāpeti rānei me te waku nui, ka taea e tēnei te whai wāhi ki te whakakore, ki te whakaiti rānei i ngā wiri iti.

3. Whakanuia te rahi o te aratohu, whakaitihia hoki te āputa taunga

Te rahi o te aratohungā takirere mono rakauhe iti te nuinga, ā, he nui te āputa ōrite o ngā takirere katoa, mai i te 0.4 ki te 1 mm, he mea āwhina tēnei ki te whakaputa i te wiri ā-pūkaha. Nō reira, ina puta he wiri ā-pūkaha iti, ka taea te whakaiti i te wiri mā te whakanui ake i te rahi o te aratohu me te whakaiti i te āputa whakauru.

4. Hurihia te āhua o te pūwero hei whakakore i te haruru

Nā te mea ko te mea e kiia nei ko te pūtake wiri o tetakirere whakahaereKa puta te pūwero i te tauranga o te pūwero, te wāhi e tere whakarerekē ai te rere me te pēhanga o te tere tiketike, mā te whakarerekē i te āhua o te mema pūwero ka taea te whakarerekē i te auau o te pūtake wiri, he māmā ake te whakatau ina kore e kaha te haruru.

Ko te tikanga motuhake ko te huri i te mata piko o te matua takirere mā te 0.5~1.0mm i roto i te awhe whakatuwheratanga wiri. Hei tauira, hetakirere whakahaere pēhanga whaiarokua tāutahia ki te taha o te wāhi whānau o tētahi wheketere. Ka pā te tangi whiowhio i puta mai i te haruru ki ngā kaimahi katoa. I muri i te tahuritanga o te mata o te matua takirere mā te 0.5mm, ka ngaro te tangi whiowhio haruru.

5. Whakakapia te wāhanga whakakā hei whakakore i te haruru

Ko ngā tikanga:

Hurihia ngā āhuatanga rere, mai i te taupū ki te rārangi, mai i te taupū ki te taupū;

Whakakapia te āhua o te matua takirere. Hei tauira, hurihia te momo mono o te pou ki te matua takirere awaawa āhua "V", ā, hurihia te momo mono o te pou o te takirere nohoanga-rua ki te momo ringaringa;

Hurihia te ringaringa matapihi ki tētahi ringaringa he kōhao iti, me ētahi atu.

Hei tauira, he maha ngā wā ka wiri te takirere nohoanga-rua DN25 i roto i te tipu tongi hauota, ā, ka whati i te hononga i waenga i te kakau takirere me te matua takirere. I muri i tā mātou whakaū he haruru, ka hurihia e mātou te matua takirere āhuatanga raina ki te matua takirere logarithmic, ā, ka whakatauhia te raruraru. Ko tētahi atu tauira ko te takirere ringaringa DN200 e whakamahia ana i roto i te taiwhanga o tētahi kāreti rererangi. I huri kaha te mono takirere, ā, kāore i taea te whakamahi. I muri i te whakawhiti i te ringaringa me te matapihi ki te ringaringa me te kōhao iti, ka ngaro tonu te hurihanga.

6. Hurihia te momo takirere whakahaere hei whakakore i te haruru

He rerekē ngā auau ā-taiao o ngā takirere whakahaere me ngā āhua hanganga rerekē. Ko te whakarerekē i te momo takirere whakahaere te huarahi tino whai hua ki te whakakore i te haruru.

He tino kaha te haruru o te takirere i te wā e whakamahia ana – ka kaha te wiri (i ngā wā tino kino, ka taea te whakangaro i te takirere), ka kaha te hurihuri (ahakoa te kakau o te takirere ka wiri, ka takai rānei), ā, ka puta he haruru kaha (tae atu ki te neke atu i te 100 tekipere). Whakakapia noa te takirere ki tētahi takirere he nui ake te rerekētanga hanganga, ā, ka puta tonu te pānga, ā, ka ngaro whakamiharo te haruru kaha.

Hei tauira, i tīpakohia he takirere ringaringa DN200 mō te kaupapa whakawhānui hou o tētahi wheketere vinylon. Kei te kitea ngā āhuatanga e toru o runga ake nei. Ka peke te paipa DN300, ka huri te mono takirere, ka neke atu i te 100 tekipere te haruru, ā, ko te whakatuwheratanga haruru he 20 ki te 70%. Whakaarohia te whakatuwheratanga haruru. He nui te nekehanga. I muri i te whakamahi i te takirere nohoanga-rua, ka ngaro te haruru, ā, he noa te mahi.

7. Tikanga hei whakaiti i te wiri cavitation

Mō te wiri cavitation i puta mai i te hinganga o ngā mirumiru cavitation, he mea maori te kimi huarahi hei whakaiti i te cavitation.

Kāore te kaha pānga i puta mai i te pahūtanga o te mirumiru e pā ki te mata totoka, inā koa te matua o te takirere, engari ka mimitihia e te wai. Kei ngā takirere ringaringa tēnei āhuatanga, nō reira ka taea te whakarerekē i te matua takirere momo mono rakau ki te momo ringaringa.

Me mahi ngā mahi katoa hei whakaiti i te pokanga, pērā i te whakanui ake i te ātete ki te whakawhāiti, te whakanui ake i te pēhanga o te kōhao whakawhāiti, te whakaiti i te pēhanga whakarārangi, whakarārangi rānei, me ētahi atu.

8. Āraihia te tikanga whakaeke ngaru pūtake wiri

Ka puta te wiri o te takirere i te ru o ngā ngaru mai i ngā pūtake wiri o waho, he mea tēnei me karo i te wā e mahi noa ana te takirere whakahaere. Mēnā ka puta taua wiri, me mahi ngā mahi e rite ana.
