Ọrụ ibu akụkụ

Arụ ọrụ akụkụ akụkụ na-ezo aka na ọnọdụ arụ ọrụ nke mgbapụta ahụ anaghị eru eru zuru oke (na-abụkarị ebe nhazi ma ọ bụ ebe kachasị mma).

Ihe ngosi pụtara ìhè nke mgbapụta n'okpuru ibu akụkụ

mgbe axial split case pump A na-arụ ọrụ na obere ibu, ọ na-emekarị: nkwụghachi n'ime ime, mgbanwe nrụgide (ntụgharị, ihe a na-akpọ ike na-akpali akpali), ike radial na-abawanye, mmụba na-abawanye na mkpọtụ mkpọtụ. N'ọnọdụ ndị siri ike, mmebi arụmọrụ na cavitation nwekwara ike ime.

Ike na-akpali akpali na isi iyi

N'okpuru ọnọdụ ibu akụkụ, nkewa na-asọgharị na recirculation na-eme na impeller na diffuser ma ọ bụ volut. N'ihi ya, a na-eme mgbanwe nrụgide gburugburu impeller, nke na-emepụta ihe a na-akpọ ike na-akpali akpali nke na-arụ ọrụ na rotor mgbapụta. N'ime nfuli ọsọ dị elu, ndị agha hydraulic ndị a na-adịghị akwụsi ike na-adịkarị karịa ike arụrụ arụ na-adịghị mma ma ya mere na-abụkarị isi mmalite nke mkpali ịma jijiji.

The recirculation nke eruba si diffuser ma ọ bụ volute azụ na impeller na site impeller azụ na mmiri n'ọdụ ụgbọ mmiri na-eme ka mmekọrịta siri ike n'etiti ndị a components. Nke a nwere mmetụta dị ukwuu na nkwụsi ike nke nkwụsi ike nke isi na-agba ọsọ na ike mkpali.

Mmiri a na-emegharị site na onye mgbasa ozi ma ọ bụ volut na-emekọrịtakwa ihe na mmiri dị n'etiti akụkụ akụkụ impeller na casing. Ya mere, ọ na-enwe mmetụta na mkpali axial na mmiri na-asọfe site na oghere ahụ, nke na-enwe mmetụta dị ukwuu na arụmọrụ ike nke rotor mgbapụta. Ya mere, iji ghọta vibration nke rotor mgbapụta, a ga-aghọta ihe ndị na-asọpụta n'okpuru ibu akụkụ.

Mmetụta mmiri na-asọpụta n'okpuru ibu akụkụ

Dị ka ọdịiche dị n'etiti ebe ọnọdụ ọrụ na ebe imewe (na-abụkarị ebe kacha mma arụmọrụ) ji nwayọọ nwayọọ na-abawanye (na-atụgharị na ntụziaka nke obere eruba), ejighị n'aka mmiri ngagharị ga-guzobere na impeller ma ọ bụ diffuser agụba n'ihi na-adịghị mma obibia eruba eruba. nke ga-eduga na nkewa nkewa (de-flow) na vibration n'ibu, tinyere ụda mkpọtụ na cavitation. Mgbe na-arụ ọrụ na akụkụ ibu (ie ala eruba udu), na agụba profaịlụ na-egosi nnọọ ejighị n'aka eruba phenomena - mmiri apụghị iso contour nke mmiri n'akụkụ nke agụba, nke na-eduga a nkewa nke ikwu eruba. Nkewa nke oke oke mmiri nke mmiri mmiri bụ usoro na-adịghị eguzosi ike n'ihe ma na-etinye aka na ntụgharị na ntụgharị nke mmiri na profaịlụ agụba, nke dị mkpa maka isi. Ọ na-eduga ná nrụgide nrụgide nke mmiri na-edozi ahụ na ụzọ mgbapụta mgbapụta ma ọ bụ ihe ndị ejikọrọ na mgbapụta, mkpọtụ na mkpọtụ. Na mgbakwunye na nkewa nke mmiri ókè oyi akwa, ndị nọgidere na-adịghị mma akụkụ ibu ọrụ njirimara nke kewaa ikpe mgbapụta na-emetụtakwa nkwụsi ike nke akụkụ dị n'èzí na-ebugharị ibugharị na ntinye ntinye (nkwụghachi azụ azụ) na n'ime ime ihe na-eme ka ọ bụrụ ihe na-eme ka ọ bụrụ ihe na-eme ka ọ dịghachi ndụ. Ntughari nke mpụga na ntinye nke impeller na-eme ma ọ bụrụ na enwere nnukwu ọdịiche dị n'etiti ọnụego nrịba (n'okpuru mmiri) na ebe nhazi. Na akụkụ ibu ọnọdụ, eruba direction nke inlet recirculation bụ megidere isi eruba direction na mmiri ọkpọ - ọ nwere ike achọpụtara n'ebe dị anya kwekọrọ na ọtụtụ suction ọkpọkọ diameters na-abụghị direction nke isi eruba.

Ọ bụrụ na axial kewara akpa mgbapụta na nnukwu isi na ike moto dị elu na-arụ ọrụ na obere ibu, njedebe kacha nta, ma ọ bụ ọbụna n'oge nwụrụ anwụ, a ga-ebufe ike mmepụta dị elu nke onye ọkwọ ụgbọ ala na mmiri a na-edozi, na-eme ka okpomọkụ ya na-ebili ngwa ngwa. Nke a n'aka nke ya ga-eduga na vaporization nke mgbapụta mgbapụta ahụ, nke ga-emebi mgbapụta ahụ (n'ihi nkwụsị nke oghere) ma ọ bụ ọbụna mee ka mgbapụta ahụ gbawaa (na-abawanye na nrụgide vapor).

Opekempe na-aga n'ihu na-erugharị kwụsiri ike

Maka otu mgbapụta ahụ, ọ bụ kacha nta na-aga n'ihu na-erugharị nkwụsi ike (ma ọ bụ pasent nke ebe ọ na-agba ọsọ kacha mma) otu mgbe ọ na-agba ọsọ na ọsọ ọsọ na agbanwe agbanwe?

Azịza ya bụ ee.
