Sechishandiso chinoshandiswa zvakanyanya mumunda wekugadziriswa kwemvura yeindasitiri uye yevagari, kuita kwe patsanura kaviri pombi yekuyamwa inoenderana zvakananga nekubudirira uye hupfumi hwehurongwa. Nekududzira zvakadzama aya ma curves ekuita, vashandisi vanogona kuita sarudzo dzakakodzera kuti vave nechokwadi chekushanda kwakanaka uye kwakavimbika kwepombi.

Iyo yekuita curve yepombi kazhinji ine akati wandei akakosha paramita kubatsira vashandisi kunzwisisa mashandiro epombi uye kusarudza pombi chaiyo. Zvichienderana nedhiyagiramu yawakapa, tinokwanisa kududzira mamwe makuru ma paramita uye curve zvinoreva:

1. X-axis (chiyero chekuyerera Q)

Flow rate (Q): The horizontal axis yegirafu inomiririra mwero wekuyerera mum³/h. Kazhinji kutaura, kukura kweyero yekuyerera, kunowedzera simba rekubuda kwepombi. Kazhinji axis iyi inowedzera kubva kuruboshwe kuenda kurudyi.



2. Y-akisi (musoro H)

Musoro (H): Axis yakatwasuka yegirafu inomiririra musoro mumamita (m). Musoro unoratidza kureba uko pombi inogona kusimudza mvura, inova chiratidzo chakakosha chekuyera simba repombi.

3. Equi-head mitsara

Equi-head mitsara: Mitsetse yakakomberedzwa mumufananidzo ndiyo mitsetse yakaenzana-yemusoro, imwe neimwe inotaridza kukosha chaiko kwemusoro (senge 20m, 50m, nezvimwewo). Mitsetse iyi inomiririra musoro uyo pombi inogona kupa pamhando dzakasiyana dzekuyerera.

4. Effect curves

Effect curves: Kunyange zvazvo curve yega yega yekushanda haina kunyatsoratidzwa mumufananidzo uyu, mune yakajairika performance curve graph, pane kazhinji kacho (η) inoshandiswa kuratidza kushanda kwepombi. Aya ma curves anoratidza kushanda kwepombi pachiyero chekuyerera chinoenderana, chinowanzo ratidzwa sechikamu. Mamwe magirafu anoshandisa mavara akasiyana kana mhando dzemitsara kusiyanisa.

5. Operating range

Operating range: Nokucherechedza mitsara yakaenzana-yemusoro mugirafu, iyo inoshanda yekushanda kweiyo patsanura kaviri pombi yekuyamwa inogona kutsunga. Nenzira yakanaka, nzvimbo yekushanda (iyo mharadzano yekuyerera uye musoro) inofanira kuva pakati pemitsara yemusoro uye iri pedyo nepamusoro-soro (BEP) yemutsara wekushanda sezvinobvira.

6. Simba rebhiza nesimba

Simba rinodiwa: Kunyange zvazvo iyi girafu inotarisa ruzivo pamusoro pekuyerera uye musoro, mumashandisirwo chaiwo, jira remagetsi rinogona kushandiswawo kunzwisisa simba rekuisa rinodiwa kuti ushandise pombi pane imwe chiyero chekuyerera.

7. Curve mienzaniso

Macurves emhando dzakasiyana: Zvichienderana nepombi modhi uye dhizaini, pachave neakawanda akasiyana akaenzana akaenzana emusoro. Aya ma curve anowanzo kucherechedzwa nemhando dzemitsara dzakasiyana kufambisa mutsauko wekuita pasi pemhando dzakasiyana kana akasiyana dhizaini mamiriro.

8. Nyaya dzinokosha

Mapoinzi akakosha ekushandisa anogona kuratidzwa mugirafu kuratidza maitiro ekushanda pasi pemutoro chaiwo kana mamiriro ehurongwa, izvo zvakakosha pakusarudzwa mumashandisirwo chaiwo einjiniya.

Iyo performance curve spectrum ye split case pombi yekuyamwa kaviri ine anotevera mabasa makuru:

1. Kuongororwa kwekuita

Kuyerera uye hukama hwemusoro: Iyo curve inogona kuratidza intuitively hukama pakati pekuyerera uye musoro, zvichibatsira vashandisi kunzwisisa kugona kwekushandisa kwepombi pasi pemamiriro akasiyana emutoro.

2. Kunyatsoongorora

Kuzivikanwa kwakanakisa kwepoinzi (BEP): Iyo yakanyanya kunaka poindi inowanzoiswa chiratidzo pagirafu, uye vashandisi vanogona kushandisa iyi poindi kusarudza iyo inoshanda yepombi kuti iwane yakanyanya kunaka simba uye hupfumi.

3. Kuenderana nehurongwa

Kuenzanisa kwemutoro: Yakasanganiswa nezvinodiwa zvehurongwa, inobvumira vashandisi kuwana iyo chaiyo pombi mhando yekushandiswa kwavo chaiko (sekupihwa kwemvura, kudiridza, maindasitiri maitiro, nezvimwewo).

4. Kusarudzwa kwepombi

Kuenzanisa uye kusarudzwa: Vashandisi vanogona kuenzanisa marudzi akasiyana emapombi kuburikidza nekuita macurves kuti vasarudze pombi nekuita kwakanyanya.

5. Kuchengetedza kwekushanda

Dzivisa cavitation: Iyo curve inogona zvakare kubatsira pakuongorora iyo mambure akanaka suction urefu (NPSH), kubatsira kudzivirira cavitation uye mamwe matambudziko, uye kugadzirisa yakachengeteka kushanda kwepombi.

6. Simba rinodiwa

Kuverenga kwesimba: Inoratidza simba rekuisa rinodiwa pamitengo yakasiyana yekuyerera, ichibvumira vashandisi kuita bhajeti resimba uye dhizaini yehurongwa.

7. Kutumira uye kugadzirisa nhungamiro

Troubleshooting: Nokuenzanisa nekavha yekushanda, vashandi vekushanda nekugadzirisa vanogona kukurumidza kuona kana pombi iri kushanda zvakanaka, uye kana pane zvikanganiso kana matambudziko ekuderedza kushanda.

8. System optimization

Kunyatso kudzora: Kuburikidza nekuita curve, vashandisi vanogona kukwidziridza dhizaini yehurongwa kuti vaone kuti pombi iri mune yakanakisa inoshanda mamiriro.

mhedziso

Iyo performance curve spectrum chishandiso chakakosha icho kwete chete chinoita kuti vashandisi vanzwisise zvakajeka maitiro ekushanda eiyo split kesi kaviri suction pombi, asi zvakare inopa hwaro hwakakosha hwekugadzira sisitimu uye mashandiro ekushanda. Nekuongororwa nesainzi uye zvine musoro uye kushandisa macurves aya, vashandisi havagone kungosarudza yakanakisa pombi mhando, asiwo kuwedzera simba rekushandisa, kuderedza mari yekugadzirisa, uye kuwedzera hupenyu hwebasa remidziyo panguva yekushanda.
