Mono rapa Sima mo te papa hinu
Whakaahuatanga:
Ka whakamahia he mono rapa hei wehe i te parapara sima mai i etahi atu wai, hei whakaiti i te poke me te pupuri i te mahi maataa.E rua nga momo moko raima e whakamahia ana i roto i te mahi sima.Ka whakarewahia te mono o raro ki mua i te parapara sima hei whakaiti i te poke o te wai i roto i te pouaka i mua i te whakangao.Ka pakaru te diaphragm i roto i te tinana mono kia puta ai te parahu sima i muri i te taenga atu o te mono ki te kara taunga.
Ko te mono o runga he tinana totoka e whakaatu pai ana mo te whakapiri ki te kara taunga me te mono o raro na te pikinga o te pehanga papu.
Ko nga raima raima he waahanga nui ki te whakatutuki i te wehenga rohe, he mea tino nui mo te whakahiato i te poka wai.Ka noho hei arai i waenga i te slurry sima me etahi atu wai poka, na reira ka aukati i te whakauru me te poke.Ko te mono o raro, me tona ahuatanga diaphragm, ka whakarite i te wehenga o te wai kia tae ra ano te slurry ciment ki tona waahi i whakaritea.I te wa ano, ko te mono o runga he tohu pono mo te taunga mai o te mono me te tuunga sima na roto i te pikinga o te pehanga papu.I te mutunga, ko te whakamahi i enei mono ka hua ake te mahi sima me te pono, he mea nui mo te pai me te noho roa.
