S / S split case pombi inonyanya kutariswa kubva pakuyerera, musoro, zvivakwa zvemvura, marongero epombi uye mamiriro ekushanda. Heino mhinduro.

Liquid zvivakwa, zvinosanganisira mvura yepakati zita, zvimiro zvemuviri, makemikari zvivakwa uye zvimwe zvivakwa, zvimiro zvemuviri zvinosanganisira tembiricha c density d, viscosity u, yakasimba chidimbu dhayamita uye gasi zviri mukati mepakati, nezvimwe, izvo zvinosanganisira musoro weiyo system, iyo inoshanda cavitation residual Quantity kuverenga uye yakakodzera pombi mhando: kemikari zvivakwa, zvinonyanya kureva makemikari ekuora uye chepfu yemvura yepakati, inova hwaro hwakakosha kusarudza kupatsanurwa. pombi yemhosva zvinhu uye rudzi rwechisimbiso che shaft yekusarudza.

Kuyerera ndeimwe yeakakosha kuita data yekusarudza pombi, iyo yakanangana nehukuru hwekugadzira uye kuendesa kugona kwechishandiso chose. Semuenzaniso, mukugadzira dhizaini yeDesign Institute, iyo yakajairwa, shoma uye yakanyanya kuyerera mwero wepombi inogona kuverengerwa. Paunenge uchisarudza simbi isina tsvina yakavhurika pombi, tora yakanyanya kuyerera sehwaro uye funga nezve yakajairika kuyerera. Kana pasina kuyerera kwakanyanya, kazhinji 1.1 nguva yekuyerera kwakajairika inogona kutorwa seyakanyanya kuyerera.

Musoro unodiwa nehurongwa nderimwe rakakosha data data yekusarudza pombi. Kazhinji, musoro unofanirwa kuwedzerwa ne5% -10% margin pakusarudza.

Zvinoenderana nekurongeka kwechishandiso, mamiriro enzvimbo, mamiriro emvura, uye mamiriro ekushanda, sarudza kusarudzwa kweyakachinjika, yakatwasuka uye mamwe marudzi emapombi (pombi, submersible, kunyura, kusavharira, kuzvidzora, giya, nezvimwe. ).

Iyo pombi yekumisikidza mamiriro eiyo mudziyo sisitimu inoreva kureba kwekutakura kwemvura, kureba kwekutakura kwemvura, uye nzira yekuendesa yemvura, senge yakaderera mvura padivi rekusveta uye yepamusoro yemvura padivi rekubuda, pamwe neimwe. dhata senge pombi inotsanangurwa nehurefu hwayo, zvinhu, pombi fittings yakatarwa, huwandu, nezvimwewo, Kuti uite kuverenga kwemusoro wetie-comb uye cheki yeNPSH.

Kune akawanda maitiro ekushanda, akadai semvura kushanda T, saturated steam force P, suction side pressure PS (absolute), discharge side container pressure PZ, urefu, ambient tembiricha, ingave kushanda kuri pakati kana kuenderera, uye chinzvimbo chepombi. yakagadziriswa kana kwete. inobvisika.

Pamapombi emvura ane viscosity yakakura kupfuura 20mm2/s (kana density inopfuura 1000kg/m3), zvinodikanwa kushandura hunhu hwepombi yekuyedza yemvura kuita curve yekuita kweviscosity (kana pasi pe density), kunyanya. iyo suction performance uye simba rekuisa. Ita masvomhu akakomba kana kuenzanisa.

Sarudza nhamba uye chiyero chekumira cheS/S kaviri suction split kesi pombi. Kazhinji, pombi imwe chete inoshandiswa pakushanda kwemazuva ose, nokuti imwe pombi yakakura yakaenzana nemapombi maduku maviri ari kushanda pamwe chete (zvinoreva kusimudza uye kuyerera kwakafanana), uye pombi huru ine hukuru hwepamusoro. Pamapombi maduku, kubva pakuona kwekuchengetedza simba, zviri nani kusarudza pombi imwe huru panzvimbo yemapombi maduku maviri, asi mumamiriro ezvinhu anotevera, mapombi maviri anogona kufungidzirwa akafanana: kuyerera kwemvura yakakura, uye imwe pombi haigoni kusvika. kuyerera uku. Pamapombi makuru anoda 50% standby rate, mapombi madiki maviri anogona kuchinjwa kuti ashande, maviri akamira (matatu pamwe chete).
