Wāhanga tuawhā Mahi rerekē-diameter o te papu vane
Ko te tikanga o te mahi whakapūmau-diameter ko te tapahi i tētahi wāhanga o te impeller taketake o te papu vane i runga i te mīhini hurihuri i te diameter o waho. I muri i te tapahi i te impeller, ka rerekē te mahi a te papu i runga i ētahi ture, ā, ka rerekē te pūwāhi mahi o te papu.
Ture tapahi
I roto i tētahi whānuitanga o te nui o te tapahi, ka taea te kī kāore i rerekē te whai huatanga o te papu wai i mua me muri i te tapahi.
Ngā raruraru e hiahia ana kia arohia i te tapahi impeller
He rohe motuhake kei te nui o te tapahi o te impeller, ki te kore ka pakaru te hanganga o te impeller, ka matotoru ake te pito putanga wai o te mata, ka piki ake te āputa i waenga i te impeller me te anga papu, ka nui rawa te heke o te pai o te papu. Ko te nui o te tapahi mōrahi o te impeller e pā ana ki te tere motuhake.
Ko te tapahi i te impeller o te papu wai he tikanga hei whakaoti i te taupatupatu i waenga i te herenga o te momo papu me ngā whakatakotoranga me te kanorau o ngā mea tuku wai, e whakawhānui ana i te whānuitanga o te whakamahinga o te papu wai. Ko te whānuitanga mahi o te papu ko te wāhanga pihi i te nuinga o te wā ka heke te pai mōrahi o te papu mā te 5% ~ 8%.
Tauira:
Tauira:SLW50-200B
Te whānui o waho o te impeller: 165 mm, te pane: 36m.
Ki te hurihia te diameter o waho o te impeller ki: 155 mm
H155/H165= (155/165)2 = 0.852 = 0.88
H(155) = 36x 0.88m = 31.68m
Hei whakarāpopototanga, ina tapahia te diameter o te impeller o tēnei momo papu ki te 155mm, ka eke te pane ki te 31 m.
Ngā Tuhipoka:
I roto i te mahi, ina he iti te maha o ngā mata, ka nui ake te pane kua whakarerekētia i te mea i tatauhia.
