Pombi yemvura yakadzika imhando yepombi inonyudzwa mumigodhi yemvura iri pamusoro kuitira kusveta hunyoro.Inoshandiswa zvakanyanya muminda yakadai sekuchera minda nekudiridza, mafekitori nemigodhi, kugovera mvura uye kudhiraivha mumaguta makuru, uye kuchenesa mvura.Iyo pombi yetsime rakadzika inofanirwa kugadziriswa kamwechete pagore kuti ive nechokwadi chekushanda kwayo kwakanaka uye kushanda zvakanaka.Tevere, ngatitaurei nezve kugadziridzwa kwemapombi etsime rakadzika uye kubata kwezvinetso zvakajairika.
Tsanangudzo yehunyanzvi yekuchengetedza mapombi etsime rakadzika.
1. Nyatsonyungudika uye kuchenesa.
2. Ongorora kusakara kwemabhengi ekukunguruka uye mabheji erubha, uye tsiva iwo pazvinenge zvakakodzera.
3. Tarisa kusakara, kukukurwa, kukotama, kugadzirisa kana kutsiviwa kweshaft.
4. Chengetedza mamiriro ekupfeka emagetsi, gadzirisa kusvetuka kwemhepo, uye kujekesa rotor dynamic balance ye impeller.
5. Tarisai shaft sealing equipment.
6. Chengetedza muviri wepombi, hapanofanira kuva nemapopu, uye nzira yekuyerera kwechigadzirwa inofanira kunge isina kuvharwa.
7. Tarisa uone kana masanga epurasitiki, pombi dzemvura uye pombi dzekubatanidza dzakamira.
8. Bvisa uye bvisa zvinhu zvakasviba mupombi.
9. Chenesa nekupfapfaidza chiyero chepombi.
2. Matambudziko akajairika uye mhinduro dzemapombi etsime rakadzika.
1. Iyo yakadzika tsime submersible pombi haigone kuyamwa mafuta kana kusimudza hakuna kukwana:
Kutenderedzwa kwepombi yemvura yecentrifugal mutsime remvura yakadzika yakakuvadzwa zvakanyanya.
Iyo mota haigone kushanda;pombi yakavharwa;pombi yakatsemuka;iyo sefa yemvura system yakavharwa;chiteshi chezvinyoro chinonyura chinoratidzwa kurwizi pamusoro;iyo mota inodzoserwa shure, iyo pombi yemuviri yakavharwa, uye impeller yakakuvadzwa;iyo musoro inodarika iyo yakayerwa ikozvino ye submersible pombi musoro;indeller inopindurwa.Iyo mota haigone kutangwa;pombi yakavharwa;pombi yakatsemuka;iyo sefa yemvura system yakavharwa;unyoro hunonyudzwa uye pamusoro perwizi rwunobuda pachena;iyo mota inodzoserwa shure, iyo pombi yemuviri yakavharwa, uye impeller yakakuvadzwa;iyo inosimudza inodarika kukosha kwakatarwa kwepombi yepasi pemvura yetsvina;indeller inopindurwa.
2. Kusagadzikana kwemhepo: Mushure mekunge yakadzika tsime pombi injini yave ichishandiswa kwenguva yakati, iyo airtightness inoputika kana, hongu, kuchembera kunokonzera kusagadzikana kwemhepo, zvichikonzera kudonha.
Mhinduro: Tsiva nhengo dzakasakara.
3. Ikozvino yepombi yetsime rakadzika yakakura zvakanyanya, uye tsono yeammeter inodedera:
Zvikonzero: kuchenesa motokari rotor;kutenderera kwehukama pakati pe shaft uye shaft sleeve haisi nyore;nekuti chinosundirwa chasakara, icho chinopinza nemhete zvinokweshana;iyo shaft yakakotama, musimboti weiyo rolling bearing haina kufanana;mvura inofamba inodzikiswa kune tsvina Pazasi pemuromo;chipfuro chinomedza nzungu.
Solution: Tsiva rolling bearing;ssust bear or thrust plate;kudzokera kufekitari kunogadzirisa.
4. Pombi yemvura iri kubvinza: Tsiva pombi yekubudisira mvura kana kutora matanho ekuvharisa nekuchimbidza.Iwe unogona kunzwa kutenderera kunotenderera kweyakadzika tsime pombi vhiri rakasimudzwa mumvura yakadzika mutsime (mudziyo wemudziyo unotendererawo zvakajairika), asi haugoni kutora unyoro kana kuti mvura shoma chete inouya.Rudzi urwu rwechinhu runowanzoitika mukukuvadzwa kwekubuda kwemvura.
Mhinduro: gadzirisa pombi yetsvina.
5. Iyo yekutanga capacitor haina kukodzera: shandura iyo capacitor neyakafanana yakatarwa uye muenzaniso.Mushure mekunge magetsi ekushandura abatanidzwa, ruzha runogona kunzwika, asi motokari yepombi yemvura yakadzika haitendereri;panguva ino, kana impeller yakashandurwa zvishoma, iyo yakadzika tsime pombi inogona kutaurira kuti simba capacitor rakakuvadzwa.
Mhinduro: Tsiva iyo capacitor.
6. Stuck pombi: Yakawanda yetsime pombi impeller inonamirwa netsvina.Iwe unogona kumonya iyo core screw ye impeller uye kubvisa iyo impeller kubvisa tsvina yakaita sejecha nedombo.Pombi yacho yaisatenderera, asi ruzha rwainzwika.Mazhinji ecentrifugal pombi yemvura yakanamira netsvina.Mvura yerwizi ine jecha rakawanda nekuda kwenzvimbo ye geological, iyo inogona kukonzera kukanganisa kune sefa.
7. Kukundikana kwesimba: Izvi zvinokonzerwawo nekufambisa kwemotokari uye kupera kwemagetsi kunokonzerwa nekuputika kwemvura mumvura yakadzika-yemvura pombi.Inogona kuputirwa ne tepi isina mvura.
8. Pombi yemvura inoputika haisi kushanda zvakanaka, mvura inobuda yepombi yemvura ye centrifugal inongoerekana yagurwa, uye motokari inomira kushanda.
chikonzero:
(1) Simba rekushanda rekugovera simba rakaderera;imwe pfungwa yemagetsi emagetsi ipfupi-inotenderera;mhepo inoputika inoputika inobviswa kana fuse inopiswa, simba rekushandura rinodzimwa;iyo motor stator coil inopiswa;impeller yakanamira;iyo mota tambo yakakuvadzwa, uye tambo yemagetsi plug yakakuvadzwa;Iyo yechitatu-phase cable haigoni kubatanidzwa;mhepo yekamuri yemotokari yakatsva.
Solution: Tarisa zvikanganiso zvakajairika zvenzira, zvikanganiso zvakajairika zvemotor winding uye kubviswa kwayo;
(2) Pombi yekupomba yemvura yakadzika uye pombi yemvura ichitsemuka:
Solution: hove yakadzika tsime pombi uye kutsiva kukuvara kwepombi dzemvura.
Tsanangudzo pfupi: Mamwe matambudziko matsva achaitika mukushanda kwemapombi akadzika matsime.Kuongorora kwakadzama uye kwakananga kunofanirwa kuitwa zvichibva pane zvakajairwa mamiriro ezvinhu, uye chirongwa chine musoro chekugadzirisa uye kugadzirisa kunofanirwa kuumbwa kuti ive nechokwadi chekushanda kwenguva refu uye yepamusoro-soro yemichina nemidziyo.
