He aha ngā wāhanga o te PDM Drill (Progressing Cavity Drill)?

He mīhini wiri hiko te PDM Drill e whakamahi ana i te wai wiri hei hiko hei huri i te pūngao pēhanga wai hei pūngao miihini.

Ngā Wāhanga

Ko te nuinga o te wā, e whā ngā huinga matua o te Wiri PDM: te takirere taha, te motuka waipēhi, te rakau kātene, me te rakau taraiwa. Ko te motuka tīwiri (mōta waipēhi) te wāhanga matua o te wiri.

1. Huihuinga Takirere Karo

Ko te takirere taha he mea tito mai i te tinana takirere, te ringaringa takirere, te matua takirere, me te puna. I raro i te pēhanga, ka paheke te matua takirere ki roto i te ringaringa takirere, ā, mā te nekehanga o te matua takirere ka huri te ahunga rere o te wai—ka rua ngā āhua o te takirere taha: taha me te kati.

I te wā e takahi ana ki roto, ki waho hoki i te kōhao: Kāore ngā kōhao o te ringaringa takirere me te tinana takirere i kati, nō reira kei te āhua takahi te takirere karo, e tuku ana i te paru i roto i te aho keri kia karo i te motuka ka tomo ki te porowhita.

Ina tae te tere rere me te pēhanga o te paru ki ngā uara paerewa kua whakatakotoria: Ka neke te matua o te takirere ki raro hei kati i te kōhao o te takirere taha. I tēnei wā, ka rere te paru mā roto i te motuka, ka huri i te pūngao pēhanga hei pūngao miihini.

Ina iti rawa te rere o te paru, ina mutu rānei te papu: Ka panaia te matua o te takirere ki runga e te puna, ā, ka whakatuwheratia te kōhao o te takirere karo—ka whakahokia te takirere ki tōna āhua karo.

2. Mōta Waipēhi

Ko te motuka waipēhi he mea hanga mai i te stator me te rotor. Ka hangaia te stator mā te werohanga i tētahi pū rapa ki roto i te pakitara o roto o tētahi paipa maitai, ā, ko tōna kōhao o roto he porowhita me ngā tawhā āhuahanga motuhake. Ko te rotor he tokotoko tīwiri me te paninga mārō. Ka honoa te rotor me te stator tetahi ki tetahi, ā, ka hangaia he kōhao porowhita hiri mā te rerekētanga o ō rāua arai hei hurihanga pūngao katoa.

Ka taea te tīmata kotahi, te tīmata maha rānei te porowhita o te rotor motuka:

Ko te iti o ngā tīmatanga o te rotor ka hua ake he tere hurihuri teitei ake, he taipana iti ake hoki;

Mā te maha atu o ngā tīmatanga o te rotor ka iti ake te tere hurihuri me te nui ake o te taipana.

3. Te Pou Kātana

Ko te mahi a te rakau kātene he huri i te nekehanga aorangi o te motuka ki te hurihanga tuaka-pūmau o te rakau taraiwa, me te tuku i te taipana me te tere hurihuri i hangaia e te motuka ki te rakau taraiwa (ā, ki te mata keri). Ko te nuinga o ngā rakau kātene he hoahoa rakau ngāwari.

4. Pouaka Puku

Ko te rakau taraiwa te kawenga mō te tuku i te mana hurihuri o te motuka ki te mata keri, me te pikau hoki i ngā kawenga axial me radial i hangaia e te taumaha i runga i te mata keri (WOB). Nō reira, me nui te pakeke o te rakau taraiwa, te ātete ki te kakahu, me te roa o te ora mahi. I tēnei wā, ka taea e te maimoatanga wera tinei te whakaroa ake i te ora mahi o te rakau taraiwa.
