Tepapu wai hikoKa whakarerekē i te rere o te wai whakamatao e rere ana i runga i ngā āhuatanga mahi o te waka, ā, ka whakatutuki i te whakahaere pāmahana o te motuka motuka. He wāhanga nui tēnei o te pūnaha whakamatao o te waka hiko hou. He wāhanga nui te whakamātautau mahi o te rangahau me te whanaketanga me te hanga o te papu wai. I tēnei wā, kāore te rangahau hangarau me te whanaketanga taputapu whakamātautau papu wai hiko motuka i te rite ki te whanaketanga o ngā papu wai hiko, ā, ko te rangahau mō ngā tikanga whakamātautau e aro nui ana ki ngā papu wai tuku iho. Ka taea e te pūnaha whakamātautau papu wai iti a NF te ine i ngā tawhā mahi pēnei i te rere o te papu, te hiki, me te whai huatanga o te pou i te pāmahana rūma, me te whakatutuki i ngā raraunga whakamātautau. Ko te kohikohinga tere o te pūmautanga hau o te papu wai. Ko te papa whakamātautau pūmautanga hau o te papu wai watea kua hoahoatia ka whakamahi i te pehanga rerekē hei kite i te pūmautanga hau o te papu wai. Kua hoahoatia te pūnaha whakamātautau whānui o te papu wai mā te whakamahi i ngā ara iahiko whakauru me ngā ara iahiko anarau.
E ai ki te paerewa ahumahi QC/T288.2-2001 me JB/T8126.9-2017 me ngā whakaritenga kaupapa here e pā ana, ko te tirotiro momo papu wai whakamatao ko te whakamātautau mahi, te whakamātautau cavitation, me ētahi atu. Mā te whakamātautau i te tere rere, te ngaohiko, me te Iahiko, te pēhanga tomo me te putanga, te tatau i te pane, te mana, te whai huatanga, te NPSH me ētahi atu tawhā mahi, ka oti te tuhi i te ānau mahi pane-rere, mana-rere, whai huatanga-rere, me te rere-NPSH o ngā papu wai hiko.
He rerekē i te papu wai whakamatao miihini, ko te tere o tepapu wai hikoKei te whakahaerehia e tana ake pūnaha whakauru, ā, mā te ngaohiko me te tohu whakahaere kua hoatu ka taea te whakahaere i te motuka kore paraihe DC ā-roto i te tere e rite ana. Ko te tikanga tuku iho o te whakamātautau i te taipana me te tere o te motuka hei tatau i te mana whakauru o te papu wai kāore e pai mō te hiko. Mō te whakamātautau i te papu wai, kua rite ki te puna hiko ka taea te whakarite hei pānui i te ngaohiko i te wā e rere ana te papu wai, tatauhia te mana whakauru o te motuka mā roto i te iahiko me te ngaohiko, kātahi ka whakareatia ki te tauwehenga whai hua hei mana whakauru o te papu wai hiko.
Ngā tawhā hangarau matua o te pūnaha whakamātautau: te whānuitanga ine rere 0~500L/min, te tika ine ±0.2%FS; te whānuitanga ine pēhanga tomo me te putanga -100~200kPa, te tika whakamātautau ±0.1%FS; te whānuitanga ine iahiko 0~30A, te tika ine ±0.1 %FS; te whānuitanga tuku ngaohiko hiko ka taea te whakarite 0~24V, te tika pānui-muri ±0.1%FS, te whānuitanga mana 0~200W; te whānuitanga ine pāmahana -20~100℃, te tika ine ±0.2%FS, te whānuitanga whakahaere pāmahana 0~80℃, te tika whakahaere ±2°C.
Mahere whakamātautau mahi whānui
E ai ki ngā paerewa whakamātautau ahumahi e tika ana, ko te whakamātautau mahi whānui o ngā papu wai e hiahia ana kia kaua e iti iho i te 8 ngā pūwāhi whakahaere rere kia rite ki ngā tere rere mōrahi me te iti rawa e haere ana i roto i te paipa whakamātautau. Mā te whakahaere PID, Whakatikatikahia te whakatuwheratanga o te takirere ōwehenga putanga hei whakau i te rere i te pūwāhi rere. Ka aroturukihia e te pūoko te pēhanga tomo me te putanga, te pāmahana, te tere rere o te paipa whakamātautau papu wai hiko i te wā tūturu, me ngā uara tawhā ngaohiko mahi me te iahiko o te papu wai hiko. Ina aroturukihia e te mita rere kei te pumau te rere i roto i te paipa i muri i tētahi wā, tuhia ngā uara tawhā o te papu wai hiko. Mā te mōhio ki te diameter o te paipa, te rerekētanga teitei i waenga i te tomo me te putanga, ngā tawhā kiato wai me te whakaterenga o te kaha ā-papa, tatauhia ngā ānau upoko-rere, te mana-rere, me te pai o te rere o te papu wai hiko i te tere kua tohua｡
