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 (m?/h) noma amalitha ngomzuzwana (L/s).
• ububanzi: Ngokuvamile ngu-10-5000 m?/h, kuye ngemodeli yepompo kanye nokusetshenziswa.

4.2 Phakamisa (H)

• incazelo:iphampu ye-centrifugalIyakwazi ukuphakamisa ubude boketshezi.
• iyunithi: Imitha (m).

• iyunithiI-kilowatt (kW).
• Ifomula yokubala:( P = \frac{Q \izikhathi H}{102 \izikhathi \eta} )
  • (Q): izinga lokugeleza (m?/h)
