Ibizwa ngokuba yi-turbomachinery ukudlulisela amandla ukuya kumanzi aqhubekekayo ngesenzo esiguqukayo seeblade kwi-impeller ejikelezayo okanye ukukhuthaza ukujikeleza kweeblade ngamandla avela kumanzi. Kwi-turbomachinery, iiblade ezijikelezayo zenza umsebenzi omhle okanye ongemuhle kumanzi, ziphakamisa okanye zinciphisa uxinzelelo lwazo. I-Turbomachinery yahlulwe yangamacandelo amabini aphambili: enye ngumatshini osebenzayo apho ulwelo lufunxa amandla okunyusa intloko yoxinzelelo okanye intloko yamanzi, njengeempompo ze-vane kunye nee-ventilators; Enye yi-prime mover, apho ulwelo lukhula khona, lunciphisa uxinzelelo, okanye intloko yamanzi ivelisa amandla, njengee-turbines zomphunga kunye nee-turbines zamanzi. I-prime mover ibizwa ngokuba yi-turbine, kwaye umatshini osebenzayo ubizwa ngokuba yi-blade fluid machine.
Ngokwemigaqo eyahlukeneyo yokusebenza kwefeni, inokwahlulwahlulwa ngohlobo lweblade kunye nohlobo lwevolumu, apho uhlobo lweblade lunokwahlulwahlulwa lube yi-axial flow, uhlobo lwe-centrifugal kunye nokuhamba okuxutyiweyo. Ngokwengcinezelo yefeni, inokwahlulwahlulwa ibe yi-blower, i-compressor kunye ne-ventilator. Umgangatho wethu wangoku weshishini loomatshini i-JB/T2977-92 ucacisa oku: Ifeni ibhekisa kwifeni enendawo yokungena yomoya eqhelekileyo, enoxinzelelo lokuphuma (uxinzelelo lwe-gauge) olungaphantsi kwe-0.015MPa; Uxinzelelo lokuphuma (uxinzelelo lwe-gauge) oluphakathi kwe-0.015MPa kunye ne-0.2MPa lubizwa ngokuba yi-blower; Uxinzelelo lokuphuma (uxinzelelo lwe-gauge) olungaphezulu kwe-0.2MPa lubizwa ngokuba yi-compressor.
Iindawo eziphambili ze-blower zezi: i-volute, i-collector kunye ne-impeller.
Umqokeleli angalathisa igesi kwi-impeller, kwaye imeko yokuhamba kokungena kwe-impeller iqinisekiswa yijometri yomqokeleli. Kukho iintlobo ezininzi zeemilo zomqokeleli, ikakhulu: i-barrel, i-cone, i-cone, i-arc, i-arc arc, i-arc cone njalo njalo.
I-Impeller ngokubanzi inesigqubuthelo sevili, ivili, i-blade, i-shaft disk, izinto ezine, isakhiwo sayo sidityaniswe kakhulu kwaye sinama-riveted. Ngokwendlela yokuphuma kwe-impeller yee-engile ezahlukeneyo zokufakela, ingahlulwa ibe zii-radial, phambili nangasemva ezintathu. I-impeller yeyona nxalenye ibalulekileyo yefeni ye-centrifugal, eqhutywa yi-prime mover, yintliziyo ye-centrifugal turinachinery, enoxanduva lwenkqubo yokudlulisa amandla echazwe yi-Euler equation. Ukuhamba ngaphakathi kwe-centrifugal impeller kuchatshazelwa kukujikeleza kwe-impeller kunye nokugoba komphezulu kwaye kuhamba kunye neziganeko zokuphuma, ukubuya kunye nokuhamba kwesibini, ukuze ukuhamba kwi-impeller kube nzima kakhulu. Imeko yokuhamba kwi-impeller ichaphazela ngokuthe ngqo ukusebenza kwe-aerodynamic kunye nokusebenza kakuhle kwesigaba sonke kwanomatshini wonke.
I-volute isetyenziswa kakhulu ukuqokelela igesi ephuma kwi-impeller. Kwangaxeshanye, amandla e-kinetic egesi anokuguqulwa abe ngamandla oxinzelelo oluqhubekayo lwegesi ngokunciphisa isantya segesi ngokuphakathi, kwaye igesi inokukhokelwa ukuba iphume kwindawo yokuphuma ye-volute. Njenge-fluid turbomachinery, yindlela esebenzayo kakhulu yokuphucula ukusebenza kunye nokusebenza kakuhle kwe-blower ngokufunda intsimi yayo yokuhamba kwangaphakathi. Ukuze siqonde imeko yokwenyani yokuhamba ngaphakathi kwe-centrifugal blower kunye nokuphucula uyilo lwe-impeller kunye ne-volute ukuphucula ukusebenza kunye nokusebenza kakuhle, iingcali zenze uhlalutyo oluninzi olusisiseko lwethiyori, uphando lovavanyo kunye nokulinganisa ngamanani kwe-centrifugal impeller kunye ne-volute.
