2024-09-14
iphampu ye-centrifugalKungumshini ojwayelekile owuketshezi onomgomo wawo wokusebenza osuselwe kumandla we-centrifugal.
Okulandelayo yilokhuiphampu ye-centrifugalIdatha enemininingwane nencazelo yokuthi isebenza kanjani:
1.isakhiwo esiyisisekelo
1.1 Umzimba wepompo
- Okubalulekile: I-cast iron, insimbi engagqwali, ithusi, njll.
- umklamo: Imvamisa isesimweni sevolute, esetshenziselwa ukuqoqa nokuqondisa ukugeleza koketshezi.
1.2 I-Impeller
- Okubalulekile: I-cast iron, insimbi engagqwali, ithusi, njll.
- umklamo: Impeller iiphampu ye-centrifugalIzingxenye eziyinhloko zivame ukuhlukaniswa zibe izinhlobo ezintathu: ivaliwe, i-semi-open futhi ivuliwe.
- Inani lamaqabunga: Ngokuvamile amaphilisi angu-5-12, kuye ngomklamo wepompo kanye nokusetshenziswa.
1.3 ekseni
- Okubalulekile: Amandla aphezulu ensimbi noma insimbi engagqwali.
- Umsebenzi: Xhuma injini ne-impeller ukuze udlulise amandla.
1.4 Ithuluzi lokuvala uphawu
- uhlobo: Mechanical seal noma ukupakisha uphawu.
- Umsebenzi: Vimbela ukuvuza koketshezi.
1.5 Ama-Bearings
- uhlobo: I-Rolling bear noma i-sliding bear.
- Umsebenzi: Isekela shaft futhi inciphisa ukungqubuzana.
2.Isimiso sokusebenza
2.1 Uketshezi lungena emzimbeni wephampu
- Indlela yokufaka amanzi: Uketshezi lungena emzimbeni wepompo ngepayipi lokungena, ngokuvamile ngepayipi elimunca kanye nevalvu yokumunca.
- Ububanzi bokungena kwamanzi: Kunqunywa ngokusekelwe ekucacisweni kwephampu kanye nezidingo zedizayini.
2.2 I-Impeller isheshisa uketshezi
- Isivinini se-impeller: Ivamise ukuba ngu-1450 RPM noma 2900 RPM (ukuguqulwa ngomzuzu), kuye ngomklamo wepompo kanye nokusetshenziswa.
- amandla e-centrifugal: I-impeller ijikeleza ngesivinini esikhulu esiqhutshwa injini, futhi uketshezi lusheshiswa ngamandla e-centrifugal.
2.3 Uketshezi lugeleza luye ngaphandle komzimba wephampu
- Idizayini yomgijimi: Uketshezi olusheshisiwe lugelezela ngaphandle eduze komzila wokugeleza we-impeller futhi lungene engxenyeni ye-volute yomzimba wepompo.
- Idizayini yevolumu: Idizayini ye-volute isiza ukuguqula amandla e-kinetic oketshezi abe amandla okucindezela.
2.4 Uketshezi oluphuma emzimbeni wephampu
- Indlela yokukhipha amanzi: Uketshezi luphinde lwehliswe amandla ku-volute bese luguqulwa lube amandla okucindezela, futhi lukhishwe emzimbeni wepompo ngepayipi lokuphuma kwamanzi.
- I-diameter ye-Outlet: Kunqunywa ngokusekelwe ekucacisweni kwephampu kanye nezidingo zedizayini.
3.inqubo yokuguqulwa kwamandla
3.1 Ukuguqulwa kwamandla e-Kinetic
- Ukusheshisa impeller: I-liquid izuza amandla e-kinetic ngaphansi kwesenzo se-impeller, futhi ijubane layo liyakhula.
- Ifomula yamandla e-Kinetic:( E_k = \frac{1}{2} mv^2 )
- (E_k): amandla e-kinetic
- (m): Isisindo soketshezi
- (v): isivinini esiwuketshezi
3.2 Ukuguqulwa kwamandla okucindezela
- Ukunciphisa ivolumu: Uketshezi lwehla ngevolumu, futhi amandla e-kinetic aguqulwa abe amandla okucindezela.
- I-Bernoulli equation( P + \frac{1}{2} \rho v^2 + \rho gh = \text{constant} )
- (P): Ingcindezi
- ( \rho ): ukuminyana koketshezi
- (v): isivinini esiwuketshezi
- (g): ukusheshisa amandla adonsela phansi
- (h): ukuphakama
4.Amapharamitha wokusebenza
4.1 Ukugeleza (Q)
- incazelo:iphampu ye-centrifugalInani loketshezi olulethwa ngesikhathi seyunithi.
- iyunithi: Ama-Cubic metres ngehora (m3/h) noma amalitha ngomzuzwana (L/s).
- ububanzi: Ngokuvamile ngu-10-5000 m3/h, kuye ngemodeli yepompo kanye nokusetshenziswa.
4.2 Phakamisa (H)
- incazelo:iphampu ye-centrifugalIyakwazi ukuphakamisa ubude boketshezi.
- iyunithi: Imitha (m).
- ububanzi: Ngokuvamile amamitha angu-10-150, kuye ngemodeli yepompo kanye nokusetshenziswa.
4.3 Amandla (P)
- incazelo:iphampu ye-centrifugalAmandla emoto.
- iyunithiI-kilowatt (kW).
- Ifomula yokubala:( P = \frac{Q \izikhathi H}{102 \izikhathi \eta} )
- (Q): izinga lokugeleza (m3/h)
- (H): Phakamisa (m)
- ( \eta ): ukusebenza kahle kwepompo (imvamisa ingu-0.6-0.8)
4.4 Ukusebenza kahle (η)
- incazelo: Ukusebenza kahle kokuguqulwa kwamandla kwephampu.
- iyunithi:amaphesenti(%).
- ububanzi: Ivamise ukuba ngu-60% -85%, kuye ngomklamo wepompo nokusetshenziswa kwayo.
5.Izikhathi zokufaka izicelo
