1. Pump Discharge Pressure

The discharge pressure ye pombi yeturbine yakadzika tsime zvinoreva simba rose rekumanikidza (chikamu: MPa) chemvura iri kutumirwa mushure mekupfuura nepapombi yemvura. Icho chiratidzo chakakosha chekuti pombi inogona kupedzisa basa rekutakura mvura. Kuyerera kwepombi yemvura kunogona kukanganisa kana kugadzirwa kwemushandisi kuchigona kuenderera semazuva ese. Nokudaro, kubudiswa kwekumanikidzwa kwepombi yemvura kunogadzirwa uye kunotsanangurwa zvichienderana nezvinodiwa zvemaitiro chaiwo.

Zvichienderana nezvinodiwa zvemaitiro ekugadzira uye zvinodikanwa zvechigadzirwa chekugadzira, iyo yekuburitsa dhizaini inonyanya kuve neinotevera nzira dzekutaura.

1.Normal kushanda kudzvinyirira: Inodiwa pombi yekubudisa simba apo bhizinesi rinoshanda pasi pemamiriro ekushanda.

2.Maximum inodiwa discharge pressure: Kana mamiriro ekugadzirwa kwebhizimisi achichinja, mamiriro ekushanda anogona kuitika anoenderana nezvinodiwa pombi discharge pressure.

3.Rated discharge pressure: Kubudiswa kwemvura kunotsanangurwa uye kuvimbiswa kuwanikwa nemugadziri wepombi. Rated discharge pressure inofanirwa kuenzana kana kuti yakakura kudarika yakajairika kushanda pressure. Kune vane mapombi inofanira kunge iri dhizaini yekuburitsa pakuyerera kwakanyanya.

4. Kunyanya kubvumirwa kubuda kwemhepo: Kunyanya kubvumirwa kubudiswa kwekumanikidza kukosha kwepombi kunotarirwa nemugadziri wepombi zvichienderana nekushanda kwepombi, simba rekugadzirisa, simba guru rekufambisa, nezvimwewo. Iyo yakawanda inobvumirwa kubuda kwemhepo inokosha inofanira kuva yakakura kudarika kana yakaenzana iyo yakanyanya kudiwa yekuburitsa kudzvanywa, asi inofanira kunge yakaderera pane yakanyanya kubvumirwa kushanda kudzvanywa kwepombi's pressure components.

2. Musoro wepombi H

Musoro wepombi yemvura (head of pombi yemvura) zvinoreva simba rinowanikwa nehuremu hwehutatu hwemvura ichipfuura nemu yakadzika zvakanaka vertical turbine pombi. Inoratidzwa naH, iyo unit is m, inova kureba kwekoramu yemvura yemvura inobuda.

Simba rinoshanda rinowanikwa mushure mekumanikidzwa kweyuniti yemvura inopfuura nepapombi, inozivikanwawo semusoro wakazara kana musoro wakazara. Tinogona zvakare kutaura nezve mutsauko wesimba pakati pemvura pakubuda nekupinza kwepombi yemvura. Asi zvinofanirwa kucherechedzwa: inongoenderana nekuita kwepombi pachayo uye haina chekuita neinopinza uye yekubuda mapaipi. Chikamu chekusimudza iN·m kana m urefu hwembiru yemvura.

Pamapombi epamusoro-soro, musiyano wekumanikidzwa pakati pepombi yekubuda uye inopinza (p2-P1) dzimwe nguva inofananidzwa kumiririra hukuru hwekusimudza. Panguva ino, kusimudza H kunogona kuratidzwa se:

Mune fomula, P1——kubuda kwepombi, Pa;

P2 ndiyo inlet pressure yepombi, Pa;

p——huwandu hwemvura, kg/m3;

g——kukwidziridzwa kwegiravhiti, m/S2.

Kusimudza chinhu chakakosha chekuita parameter yepombi yemvura, iyo yakavakirwa pane zvinodiwa petroleum nemakemikari maitiro uye zvinodiwa nemugadziri wepombi.

1. Musoro wekushanda wakajairwa: Musoro wepombi wakatarwa nekumanikidza kwekuburitsa uye kusveta kudzvanywa kwepombi pasi pemaitiro ekugadzirwa kwemaitiro ebhizinesi.

2. Iyo yakanyanya kukwirisa inodiwa ndeyekusimudza kwepombi kana iyo yakanyanya kudiwa yekuburitsa kumanikidza (iyo suction pressure inoramba isingachinji) inoshanduka kana bhizinesi mamiriro ekugadzira achinja.

3. Yakatemerwa musoro Musoro wepombi yemvura iri pasi peiyo impeller dhayamita, yakayerwa kumhanya, yakayerwa kusveta uye kuburitsa kumanikidza. Ndiwo musoro wakatemerwa uye unovimbiswa nemugadziri wepombi, uye kukosha kwemusoro uku kunofanirwa kuenzana kana hukuru kupfuura wenguva dzose unoshanda musoro. Kazhinji, kukosha kwayo kwakaenzana nehuwandu hunodiwa kusimudza.

4. Musoro wekuvhara Musoro wekuvhara musoro kana kuyerera kwepombi yemvura kwaita zero. Ndiyo yakanyanya kukwirisa muganhu wepombi yemvura. Kazhinji, dhizaini yekuburitsa pasi pekusimudza iyi inotaridza iyo yakanyanya kubvumirwa kushanda kumanikidza kwezvinomanikidza senge pombi muviri.
