1. Basic mitundu ndi makhalidwe.
Mapampu a mphete amadzi amatha kugawidwa m'magulu otsatirawa molingana ndi mapangidwe osiyanasiyana.
■ Mapampu a mphete amadzi okhala ndi gawo limodzi: gawo limodzi limatanthauza kuti pali chopondera chimodzi chokha, ndipo kuchita kamodzi kumatanthauza kuti chopondera chimayenda kamodzi pa sabata, ndipo kuyamwa ndi kutulutsa kumachitika kamodzi.Mpweya womaliza wa mpope uwu ndi wapamwamba, koma kuthamanga kwa kupopera ndi mphamvu ndizochepa.
■ Pampu ya mphete yamadzi yokhala ndi magawo awiri: gawo limodzi limatanthawuza mpumulo umodzi wokha, kuchita kawiri kumatanthawuza kuti sabata iliyonse chiwongolerocho chimazungulira, kuyamwa ndi kutulutsa kumachitika kawiri.M'malo othamanga omwewo, pampu ya mphete yamadzi yochita kawiri kuposa pampu yamadzi yochita kamodzi imachepetsa kwambiri kukula ndi kulemera kwake.Pamene chipinda chogwirira ntchito chimagawidwa mozungulira mbali zonse za mpope, katundu yemwe amagwira ntchito pa rotor amakhala bwino.Liwiro la kupopera kwa mtundu uwu wa pampu ndilapamwamba ndipo mphamvu yake ndi yokwera, koma mpweya womaliza ndi wotsika.
■ Mapampu a mphete a madzi a magawo awiri: Mapampu a mphete a madzi a magawo awiri ndi mapampu omwe amagwira ntchito imodzi motsatizana.M'malo mwake, ndi ma impeller awiri amtundu umodzi wokhala ndi mphete yamadzi omwe amagawana kulumikizana wamba kwa mandrel.Chinthu chake chachikulu ndi chakuti akadali ndi liwiro lalikulu la kupopera pamtunda wapamwamba wa vacuum ndi chikhalidwe chokhazikika chogwira ntchito.
■ Pampu ya mphete yamadzi am'mlengalenga: Pampu ya mphete yamadzi am'mlengalenga kwenikweni ndi seti ya ejector ya mumlengalenga motsatizana ndi mpope wa mphete yamadzi.Pampu ya mphete yamadzi imalumikizidwa motsatizana ndi mpope wam'mlengalenga kutsogolo kwa pampu ya mphete yamadzi kuti awonjezere kutulutsa komaliza komanso kukulitsa kuchuluka kwa ntchito ya mpope.
Mapampu a mphete amadzi ali ndi ubwino wotsatirawu poyerekeza ndi mitundu ina ya mapampu opangira makina.
▪ Kapangidwe kake, kachitidwe kocheperako kamene kamapangidwa, kosavuta kukonza.Ntchito yosavuta komanso kukonza kosavuta.
▪ Kapangidwe kameneka, pampu nthawi zambiri imalumikizidwa mwachindunji ndi injini ndipo imakhala ndi rpm yayikulu.Ndi miyeso yaying'ono yamapangidwe, mphamvu yayikulu yotulutsa imatha kupezeka.
▪ Hakwila nawu yuma yinakumwekesha nawu mudimu wamuchipompelu, muloña wakwila yuma yinakumwekesha yuma yatama.Kusindikiza pakati pa magawo ozungulira ndi okhazikika kungathe kuchitidwa mwachindunji ndi chisindikizo cha madzi.
▪ Kusintha kwa kutentha kwa gasi wopanikizidwa m'chipinda chopopera n'kochepa kwambiri ndipo kumatha kuonedwa ngati kuponderezana kwa isothermal, kotero kuti mpweya woyaka ndi wophulika ukhoza kuponyedwa kunja.
▪Kupanda valavu yotulutsa mpweya ndi malo ophwanyika kumathandiza pampu kuchotsa mpweya wafumbi, mpweya wosungunuka ndi madzi osakaniza.
2 Kuipa kwa mapampu a mphete zamadzi.
▪ Kuchita bwino pang'ono, nthawi zambiri pafupifupi 30%, bwino mpaka 50%.
▪ Vacuum yochepa.Izi si chifukwa cha zofooka structural, koma chofunika kwambiri, ndi ntchito madzimadzi machulukitsidwe nthunzi kuthamanga.
Kawirikawiri, mapampu a mphete amadzi amagwiritsidwa ntchito kwambiri chifukwa cha ubwino wawo wapadera monga kuponderezedwa kwa isothermal ndi kugwiritsa ntchito madzi ngati madzi osindikizira, kuthekera kotulutsa mpweya woyaka, wophulika ndi wowononga, komanso kuthekera kotulutsa mpweya wokhala ndi fumbi ndi chinyezi.

4 Mfundo zazikuluzikulu posankha
I. Kutsimikiza kwa mtundu wa mpope wa ring ring vacuum
Mtundu wa mpope wopopera mphete umatsimikiziridwa ndi sing'anga yopopera, voliyumu yamafuta ofunikira, digiri ya vacuum kapena kuthamanga kwa mpweya.
II.Chachiwiri, mpope wamadzi otsekemera amadzi ayenera kumvetsera mfundo ziwiri pambuyo pa ntchito yabwino.
1, Momwe ndingathere, kuchuluka kwa vacuum kwa mpope wakupumulira kumafunika kukhala m'dera lapamwamba kwambiri, ndiko kuti, kugwira ntchito m'dera la gawo lofunika kwambiri la vacuum kapena kuthamanga kofunikira kwambiri, kuti mutsimikizire. kuti pampu ya vacuum imatha kugwira ntchito moyenera molingana ndi zofunikira komanso zofunikira.Kugwira ntchito pafupi ndi mulingo wochuluka wa vacuum kapena kuthamanga kwamphamvu kwapampu ya vacuum kuyenera kupewedwa.
Kugwira ntchito m'derali sikungokhala kosakwanira, komanso kosakhazikika komanso kovutirapo kunjenjemera ndi phokoso.Kwa mapampu a vacuum omwe ali ndi mpweya wambiri, omwe akugwira ntchito mkati mwa dera lino, cavitation nthawi zambiri imapezeka, zomwe zimawonekera ndi phokoso ndi kugwedezeka mkati mwa mpope wa vacuum.Kuchuluka kwa cavitation kungayambitse kuwonongeka kwa thupi la mpope, impeller ndi zigawo zina, kuti pampu ya vacuum isagwire ntchito bwino.
Zitha kuwoneka kuti pamene mpweya wotsekemera kapena mpweya womwe umafunidwa ndi pampu ya vacuum sipamwamba, chofunika kwambiri chingaperekedwe pampope imodzi yokha.Ngati kufunikira kwa digiri ya vacuum kapena kuthamanga kwa gasi ndikwambiri, mpope wagawo limodzi nthawi zambiri sungathe kukwaniritsa, kapena, kufunikira kwa mpope kumakhalabe ndi mpweya wochuluka ngati muli ndi digiri ya vacuum yapamwamba, ndiye kuti, kufunikira kokhotakhota. ndi yosalala mu digiri ya vacuum yapamwamba, pampu yamagawo awiri imatha kusankhidwa.Ngati vacuum chofunika ndi pamwamba -710mmHg, Roots madzi mphete vacuum unit angagwiritsidwe ntchito ngati vacuum kupopa chipangizo.
2, Molondola sankhani mpope vakuyumu malinga ndi mphamvu yopopera yofunikira ya dongosolo
Ngati mtundu wa pampu ya vacuum kapena vacuum unit wasankhidwa, chitsanzo choyenera chiyenera kusankhidwa molingana ndi mphamvu yopopa yofunikira ya dongosolo.
Makhalidwe amitundu yosiyanasiyana ya mapampu a vacuum mphete yamadzi ndi awa.
