Ceev ceev
1. Tshwj xeeb ceev txhais
Qhov tshwj xeeb ceev ntawm lub twj tso kua mis dej yog abbreviated raws li kev ceev, uas feem ntau yog sawv cev los ntawm lub cim ns.Qhov tshwj xeeb ceev thiab kev sib hloov ceev yog ob lub ntsiab lus sib txawv.Qhov tshwj xeeb ceev yog cov ntaub ntawv dav dav suav los ntawm kev siv cov ntsuas tsis zoo Q, H, N, uas qhia cov yam ntxwv ntawm cov twj tso kua dej.Nws tseem tuaj yeem raug hu ua kev ntsuas.Nws yog ze ze rau cov qauv zoo ntawm lub twj tso kua mis impeller thiab kev ua haujlwm ntawm lub twj tso kua mis.
Kev suav cov mis ntawm Specific Speed hauv Suav teb
Kev suav cov mis ntawm Specific Speed txawv teb chaws
1. Q thiab H xa mus rau tus nqi ntws thiab lub taub hau ntawm qhov ua tau zoo tshaj plaws, thiab n yog hais txog kev tsim ceev.Rau tib lub twj tso kua mis, qhov tshwj xeeb ceev yog ib qho nqi.
2. Q thiab H nyob rau hauv cov mis xa mus rau tus tsim txaus txaus thiab tsim lub taub hau ntawm ib leeg-suction ib-theem twj tso kua mis.Q / 2 yog hloov rau ob lub twj tso kua mis;Rau ntau theem twj tso kua mis, lub taub hau ntawm thawj-theem impeller yuav tsum tau hloov pauv rau kev suav.

1. Lub twj tso kua mis uas tsis tshua muaj kev ceev txhais tau hais tias lub taub hau siab thiab cov dej me me, thaum lub twj tso kua mis nrog lub siab tshwj xeeb txhais tau tias lub taub hau qis thiab ntws loj.
2. Lub impeller nrog qis tshwj xeeb ceev yog nqaim thiab ntev, thiab lub impeller nrog kev ceev ceev yog dav thiab luv.
3. Lub twj tso kua mis tshwj xeeb qis yog nquag hump.
4, lub twj tso kua mis tshwj xeeb qis, lub zog ntawm lub zog me me thaum qhov ntws yog xoom, yog li kaw lub valve kom pib.Cov twj tso kua mis tshwj xeeb ceev (cov twj tso kua mis sib xyaw, axial flow twj tso kua mis) muaj lub zog loj ntawm xoom ntws, yog li qhib lub valve kom pib.
