For pasi pemvura yakatwasuka turbine pombi musevhisi, tinokurudzira kushandisa dzvinyiriro yemunharaunda kubatsira mukufungidzira kugadzirisa uye kugadzirisa matambudziko.

Pombi Inoshanda Nzvimbo

Mapombi akagadzirirwa kuzadzisa uye kushanda pane yakatarwa dhizaini kuyerera uye kusiyanisa kudzvanywa / musoro. Kushanda mukati me10% kusvika 15% yeBest Efficiency Point (BEP) kunoderedza kudedera kunoenderana nekusadzikama kwemasimba emukati. Ziva kuti kutsauka kwezana kubva kuBEP kunoyerwa maererano nekuyerera kweBEP. Iyo inowedzera iyo pombi inoshandiswa kubva kuBEP, iyo inovimbika zvishoma.

Iyo pombi yepombi ndeyekushanda kwemichina kana pasina dambudziko, uye nzvimbo yekushanda yepombi inonyatsoita inogona kufanotaurwa nekudzvinyirirwa kwekusveta uye kubuda kwemhepo kana kuyerera. Kana iyo midziyo ikatadza, ese matatu ari pamusoro apa paramita anofanirwa kuzivikanwa kuti aone kuti dambudziko nderei papombi. Zvisinei, pasina kuyera hunhu huri pamusoro, zvakaoma kuona kana paine dambudziko neiyo submersible. vertical turbine pombi. Naizvozvo, zvakakosha kuisa mita yekuyerera uye kusveta uye kuburitsa magaji ekumanikidza.

Kamwe chiyero chekuyerera uye kusiyanisa kudzvinyirirwa / musoro zvazivikanwa, varonge pagirafu. Nzvimbo yakarongwa ingangove iri padyo nepombi curve. Kana zvirizvo, unogona kuona nekukurumidza kuti kure sei kubva kuBEP michina iri kushanda. Kana iyi poindi iri pazasi pepombi curve, inogona kutariswa kuti pombi haisi kuita seyakagadzirirwa uye inogona kunge iine imwe nzira yekukuvadza mukati.

Kana pombi ichigara ichimhanya kuruboshwe kweBEP yayo, inogona kutorwa seyakakura uye zvinogoneka mhinduro dzinosanganisira kucheka impeller.

Kana pombi yeturbine inodzika pasi ichigara ichimhanya kurudyi kweBEP yayo, inogona kunzi haina hukuru. Zvinogoneka zvinogadzirisa zvinosanganisira kuwedzera impeller dhayamita, kuwedzera pombi kumhanya, kupuruzira vharafu yekuburitsa kana kutsiva pombi neimwe yakagadzirirwa kugadzira kuyerera kwepamusoro. Kushandisa pombi padhuze neBEP yayo ndiyo imwe yenzira dzakanakisa dzekuona kuvimbika kwakanyanya.

Net Positive Suction Head

Net Positive Suction Head (NPSH) chiyero chemaitiro emvura kuti irambe iri mvura. Kana NPSH iri zero, mvura inenge iri pamhute yayo kana painofashaira. Iyo Net Positive Suction Head Inodiwa (NPSHr) curve yepombi yecentrifugal inotsanangura musoro wekusveta unodiwa kudzivirira kuti mvura isanyungudike kana ichipfuura nepaburi repasi paburi rekukweva.

Iyo inowanikwa net positive suction head (NPSHHa) inofanira kunge yakakura kudarika kana kuenzana neNPSHr kudzivirira cavitation - chiitiko apo mabhubhu anoumba munzvimbo yakaderera yekudzvanya panzvimbo yekusveta impeller uye yobva yadonha nechisimba munzvimbo yakakwira yekumanikidza, zvichikonzera kudurura zvinhu uye. pombi vibration, izvo zvinogona kutungamira mukutadza uye kutadza kwechisimbiso muchikamu chidiki chehupenyu hwavo hwese. Pakuyerera kwemazinga, iyo NPSHr kukosha pane submersible vertical turbine pombi curve inowedzera zvakanyanya.

A suction pressure gauge ndiyo inonyanya kushanda uye yakarurama nzira yekuyera NPSHa. Pane zvikonzero zvakawanda zvakasiyana zvepasi NPSHa. Zvisinei, zvikonzero zvinonyanyozivikanwa itambo yekusveta yakavharika, vharuvhu yekusveta zvishoma yakavharwa, uye sefa yakavharika yekusveta. Zvakare, kumhanya pombi kurudyi kweBEP yayo kuchawedzera NPSHr yepombi. A suction pressure gauge inogona kuiswa kubatsira mushandisi kuona dambudziko.

Suction Filters

Mapombi mazhinji anoshandisa mafirita ekusveta kudzivirira zvinhu zvekune dzimwe nyika kupinda nekukuvadza impeller uye volute. Dambudziko nderekuti vanovhara nekufamba kwenguva. Pavanovhara, kudonha kudonha kwesefa kunowedzera, izvo zvinoderedza iyo NPSHa. Yechipiri yekusveta pressure gauge inogona kusetwa kumusoro kwesefa kuti ienzanise neyepombi yekusveta pressure geji kuona kana sefa yakavharika. Kana mageji maviri asiri kuverenga zvakafanana, zviri pachena kuti sefa plugging iripo.

Chisimbiso Tsigiro Yekudzvanya Kutariswa

Nepo zvisimbiso zvemuchina zvisiri nguva dzose izvo zvinokonzeresa, zvinoonekwa zvakanyanya seyakanyanya kutadza nzvimbo ye submersible vertical turbine pombi. API chisimbiso chekutsigira pombi zvirongwa zvinoshandiswa kuchengetedza kwakaringana lubrication, tembiricha, kudzvanywa uye / kana kuenderana kwemakemikari. Kuchengetedza chirongwa chepombi kwakakosha kuti uwedzere kuvimbika. Naizvozvo, kunyatsotarisisa kunofanirwa kubhadharwa kune chiridzwa chechisimbiso chekutsigira system. Kugezesa kwekunze, kudzima chiutsi, mapoto anovharisa, masisitimu ekutenderera uye magasi egasi anofanirwa kunge akashongedzerwa nemageji ekumanikidza.

mhedziso

Ongororo inoratidza kuti isingasviki 30% yemapombi ecentrifugal akashongedzerwa nemageji ekuyamwa. Nekudaro, hapana huwandu hwechiridzwa hunogona kudzivirira kutadza kwemidziyo kana iyo data isina kunyatsocherechedzwa uye kushandiswa. Ingave iri purojekiti nyowani kana retrofit purojekiti, kuisirwa kwakakodzera in-situ chiridzwa kunofanirwa kutariswa kuti ive nechokwadi chekuti vashandisi vanogona kuita kwakakodzera kugadzirisa uye kugadzirisa kwekufungidzira pamidziyo yakakosha.
