1,Te kaupapa mahiKo te pūwero piston kei roto i te rango, te takirere me te rango mō te nekehanga tauutuutu o te piston i hangaia e te rōrahi mahi e huri tonu ana kia oti. Ki te kore koe e whakaaro ki te mahi tuturu o te pūwero piston compressor e ngaro ana te rōrahi me te ngaronga pūngao (arā, ko te tukanga mahi tino pai), ko te porowhita piston compressor compressor ia hurihanga o te wiki kia oti te mahi, ka taea te wehewehe ki te tukanga momi, te kōpeketanga me te tukanga whakaputa.
Te tukanga kōpeketanga:Ka neke ake te piston mai i te pūwāhi mutu o raro, ka kati te takirere momi me te tuku, ka pēhia te hau i roto i te rango kati, ka heke haere te rōrahi o te rango, ka piki haere te pēhanga me te pāmahana tae noa ki te ōrite te pēhanga hau o te rango me te pēhanga putanga. Ko te tukanga pēhanga e kiia ana he tukanga isentropic.
Te tukanga whakaputa hau: Ka piki tonu te piston, ā, ka nui ake te pēhanga hau o te rango i te pēhanga o te putanga hau, ka tuwhera te takirere putanga hau, ka pana te pēhanga hau o te rango i roto i te piston ki waho o te rango ki roto i te paipa putanga hau, tae noa ki te nekehanga o te piston ki te pito o runga. I tēnei wā, nā te kaha o te puna o te takirere putanga hau me te mahi a te kaha o te takirere, ka kati te pito putanga hau o te takirere putanga hau.
2, ngā tono pūwero piston
Ngā tono matua: te mākete rokiroki makariri me te mākete tio me te pouaka whakamātao, he nui ake te whakamahinga o ngā kōpeke piston haurua-hermetic; ngā tono iti iho: te hauhautanga pouaka whakamātao arumoni.
Ko te pūwero piston haurua-hermetic mō te rokiroki makariri ka peia e te motuka pou-whā, ā, ko tōna mana whakatauranga kei waenga i te 60-600 KW. Ko te maha o ngā rango he 2 - 8, tae atu ki te 12. 2, tono pūwero piston
Ngā tono matua: te mākete rokiroki makariri me te pouaka whakamātao me te tio, he nui ake te whakamahinga o te pūwero piston haurua-hermetic; ngā tono iti ake: te pouaka whakamātao arumoni me te hauhautanga.
Pūwero piston haurua-hermeticmōrokiroki makaririe peia ana e te motuka pou-whā, ā, ko tōna mana whakatauranga kei waenga i te 60-600KW. Ko te maha o ngā rango he 2 - 8, tae atu ki te 12.
3, ngā painga o ngā pūwero piston
(1) Ka taea te whiwhi i te pēhanga e hiahiatia ana ahakoa te tere rere, me te whānuitanga o ngā pēhanga tukunga tae atu ki te 320MPa (ngā tono ahumahi) tae atu ki te 700MPa, (i roto i te taiwhanga).
(2) Te kaha o te mīhini kotahi mō tetahi tere rere tae atu ki te 500 m3/min.
(3) He iti ngā rauemi e hiahiatia ana i roto i te awhe pēhanga whānui, he mea hanga te nuinga ki ngā rauemi maitai noa, he māmā ake te tukatuka me te iti ake te utu ki te hanga.
(4) Ki te nui ake te pai o te wera, ka taea e ngā waeine nui me ngā waeine rahi-waenga te eke ki te pai o te adiabatic 0.7~0.85.
(5) He kaha te urutau i te wā e whakarerekē ana i te rahinga hau, arā, he whānui ake te awhe putanga hau, ā, kāore e pāngia e te pēhanga teitei, iti rānei, ā, ka taea te urutau ki te awhe pēhanga whānui me ngā whakaritenga rahinga pouaka whakamātao.
(6) Kāore te taumaha me ngā āhuatanga o te hau e pā ki te mahi a te pūwero, ā, ka taea te whakamahi i te pūwero kotahi mō ngā hau rerekē.
(7) He tino māmā te mīhini taraiwa, he maha ngā motuka hiko e whakamahia ana, kāore he tere e whakahaeretia ana, ā, he tino pai te mahi.
(8) He pakari ake te hangarau o te pūwero piston, ā, ko te wheako kua kohia hei whakaputa.
4, ngā ngoikoretanga o ngā pūwero piston
(1) he hanganga uaua, he matotoru, he wāhanga e mau ana, he papa nui, he nui te haumi, he mahi tiaki, he poto ake te whakamahinga o te huringa, engari i muri i te mahi ka taea te neke atu i te 8000 hāora.
(2) Kāore i te tere te mīhini, he nui, he taumaha hoki, ā, ko te nui o te putanga hau o tētahi mīhini kotahi he iti iho i te 500 m3/min.
(3) Te wiri i te whakahaerenga o te mīhini.
(4) Kāore te hau putanga e haere tonu, he pāorooro te rere o te hau, e ngāwari ai te wiri o te paipa, ā, he maha ngā wā ka pakaru te whatunga paipa, ngā wāhanga mīhini rānei nā te pāorooro o te hau me te haruru i ngā wā kino.
(5) Te whakahaere rere mā te whakamahi i ngā takirere rōrahi kua tautokona, ngā takirere karo rānei, ahakoa he māmā, he watea, he pono hoki, engari he nui te ngaronga o te mana me te whakaiti i te pai o te mahi i te wā e whakahaeretia ana te kawenga wāhanga.
(6) Ngā pūwero hinu-whakahinuhinu me te hinu i roto i te hau e tika ana kia tangohia.
(7) Ngā tipu nui e whakamahi ana i ngā huinga pūwero maha ina he maha ngā kaiwhakahaere, ina he nui rānei te kaha o te mahi.
