Ruzivo rwekutanga rwemapombi emakemikari

Nzira yekusarudza pombi yakanyatsokodzera yakagara iri chinhu chine hanya zvikuru nevanhu. Hazvisi nyore kuti usarudze kodzerokemikari pombinekuti zvese izvi zvinhu zvine basa: chiitiko, midhiya, zvinhu, nezvimwe.

Isu tine pano sumo yakadzama yemhando dzakasiyana dzemapombi, kuitira kuti tikupei pachena pachena kuti ndeupi rudzi rwepombi yemakemikari yaunofanira kusarudza.

Kusarudza pombi, tinofanira kutanga tanzwisisa uye kugona misimboti yekusarudzwa kwepombi yemakemikari. 

1. Mhando yepombi yakasarudzwa uye kushanda maererano nechigadzirwakuyerera, musoro, kudzvanywa, tembiricha, cavitation kuyerera, kuyamwa uye mamwe maitiro paramita.

2. Inofanira kujekesa zvinodiwa zvepakati maitiro.

Pakutakura kwepombi inobvira, inoputika ine muchetura kana inodhura media, inoda chisimbiso chakavimbika kana kushandiswa kwemapombi asina kubuda, senge.magnetic drive pombi,diaphragm pombi,pombi yenhovo.

3. Kutapurirana kwepombi inoodza media, kuvimbika kwemuchina, ruzha rwakaderera, kuzunguzika.

4. Upfumi hunofanira kufunga nezvemutengo wemidziyo, mari yekushandisa, kuchengetedza uye manejimendi inodhura yakaderera yakazara mutengo.

5. Zviitiko zvakajairika, kusarudzwa kwepombi yemakemikari:

(1) centrifugal pombinehupamhi hwepamusoro, hukuru hudiki, huremu huremu, kushanda kwepamusoro, kuyerera kwakakura, chimiro chakareruka, pasina pulsation yekuputira, kushanda kwakagadzikana, kushanda nyore uye nyore kugadzirisa nezvimwe zvakadaro.

(2) Pane kuyerwa zvinodiwa, kusarudzwa metering pombi.

(3) Musoro zvinodiwa zvakakwirira kwazvo, kuyerera kudiki uye hapana kwakakodzera kuyerera kudiki kwakakwira-simudza centrifugal mota pombi inogona kushandiswa, iyo inosarudzika inodzosera pombi, senge cavitation zvinodiwa haisi yakakwirira inogonawo kushandisa vortex pombi.

(4) Musoro wakanyanya kuderera, kuyerera kukuru, kusarudzwa kweaxial kuyerera pombi uye yakasanganiswa yekuyerera pombi.

(5) Medium viscosity (yakakura kupfuura 650 ~ 1000mm2 / s), funga nezvesarudzo yepombi inotenderera kana pombi inodzokororwa (gear pombi, screw pump)

(6) Pakati pegasi ye75%, kuyerera kwehuwandu idiki uye viscosity iri pasi pe37.4mm2 / s, kusarudzwa kwepombi yevortex.

Kutanga kwekazhinji kanapombi yekudiridzanguva dzekusagadzikana, dzinofanirwa kushandisa self-priming performance yepombi, sengeself-priming centrifugal pombi,self-priming vortex pombi, pneumatic (yemagetsi) yakatsaurirwa pombi.

Kutsvaga maconvection mativi uchishandisa corrosion-resistant material pombi kusarudzwa kunoenderana nemaitiro kunofanirwa kuve kwakavakirwa pakupihwa kwemvura uye kudhiraivha zvinodiwa, kubva pazvinhu zvishanu zvinofanirwa kutariswa. 

1. Kuyerera ndeimwe yeakakosha data data yepombi, inoenderana zvakananga nehuwandu hwekugadzira uye kutapurirana kwechigadzirwa chose. Zvakadai seDesign Institute process dhizaini inogona kuverenga pombi yakajairwa, shoma, yakakwira mhando nhatu dzetraffic. Sarudza pombi, iyo yakanyanya kuyerera sehwaro, uchifunga nezve yakajairika kuyerera, mukusavapo kwekuyerera kwakanyanya, kazhinji inodiwa 1.1 nguva yakajairika kuyerera seyakanyanya kuyerera.

2. Device system inodiwa kusimudza pombi ndeimwe yakakosha data data, iyo yakawanda inoshandiswa yeamplification 5% -10% margin kusvika kumusoro mushure mekusarudzwa.

3. Liquid properties, zvinosanganisira zita remvura yepakati, zvinhu zvemuviri, makemikari zvivako uye zvimwe zvinhu, izvo zvine chokuita nemusoro wegadziriro, kuverenga kweNPS kunobudirira uye rudzi rwakakodzera rwepombi, kusarudzwa kwezvinhu zvepombi uye kushandisa iyo rudzi rwechisimbiso chemhando ye shaft.

4. Mamiriro ekugadzirisa pombi yegadziriro yekuisa inoreva kureba kwekudyisa kwemvura, chinhambwe chemvura inotumira, chiyero chemvura chidiki chedivi rekusveta, huwandu hwemvura inoyerera yedivi rekubuda, nezvimwe, uye zvakatemwa. , kureba, zvinhu, uye zvichingodaro, kuitira kuenderera mberi nekuverenga musoro wecomb uye cheki yeNPSH.

5. Kutsunga kwemamiriro ekushanda, akadai semvura inoshandiswa T yakazara mhute pressure, suction side pressure (absolute), discharge side mudziyo pressure, urefu, ambient tembiricha oparesheni iri gap kana kuenderera, ingave nzvimbo yepombi yakagadziriswa kana kufambiswa. Ihwaro hwakakosha hwekusarudza. Zvishandiso zvakaita se AFB simbi isina simbi isingadziviriri pombi, CQF engineering epurasitiki magineti drive pombi.

Pakufambiswa kwezvimedu zvakasimba zvine midhiya, kushandiswa kwezvinhu zvinobatika kunoda kupfeka-resistant zvinhu, kana zvichidikanwa, shaft chisimbiso chine mvura yakachena sukurudza.

Kurongeka kwepombi yemapombi emakemikari

Mukugadzira pombi yekugadzira, inofanirwa kucherechedza zvinotevera:

A. Chisarudzo chinonzwisisika chepombi dhayamita, dhayamita yepombi, pachiyero chekuyerera kwakafanana, kuyerera kwevelocity idiki, kurasikirwa kwekupokana kudiki, asi mutengo wakakwira, dhayamita yepombi idiki, ichaita kuti kuwedzere kwakasimba kwekurasikirwa kwekupokana. , musoro wepombi unowedzera Nekuwedzera kwesimba, mari uye mari yekushanda yakawedzera. Saka zvinofanirwa kutariswa kubva kune tekinoroji uye yehupfumi maonero.

B. Exhaust pombi uye zvigadziro zvayo zvinofanira kukwanisa kuyeuka kudzvinyirira kwakanyanya.

C. pombi marongero anofanirwa kurongeka zvakatwasuka sezvinobvira kuderedza pombi dzekuisa uye kuderedza kureba kwepombi kunofanirwa kutenderedzwa kana dhayamita yekubhenda yepombi yegokora ichifanira kuita 3 kusvika ka5 pakona zvakanyanya kupfuura. 90 Lt; 0 & gt; C.

D. Rutivi rwekubuda rwepombi runofanira kunge rwakagadzirirwa mavharuvhu (bhora kana globe valve, nezvimwewo) uye cheki valve. Ivhavha inoshandiswa kugadzirisa nzvimbo yekushanda yepombi. Ivhavha yecheki inodzivirira pombi kuti irege kudzokera shure kana mvura ichidzoka uye inodzivirira pombi kubva pakurova nyundo yemvura. (Kana iyo mvura ichidzoka, ichave neyakakura reverse pressure, iyo pombi kukuvara).
