Kev piav qhia:
Portable centrifugal twj tso kua mis mounted ntawm wheeled chassis rau hloov tau yooj yim multipoint. Muab cov BOSP series 'kev huv huv cov yam ntxwv - suav nrog cov twj tso kua mis lub cev thiab qhov crevice-dawb tsim - nrog rau kev txav mus los rau kev ua cov ntawv thov. Kev tsim kho stainless hlau ua tau raws li 3A cov qauv, thaum qhov ncaj qha -mounted impeller tswj<28µm surface roughness for optimal cleanability. Widely used in food processing, cosmetics manufacturing, and mobile CIP systems.
Suction stroke (lub siab nqus):
Lub tshuab nqus plua plav ntawm lub twj tso kua mis yog hais txog lub siab ntawm cov kua uas tau muab tso rau hauv lub twj tso kua mis (unit: MPa), qhov nqus siab tus nqi ntawm lub twj tso kua mis yuav tsum siab dua qhov siab ntawm cov kua dej ntws tawm ntawm lub twj tso kua mis. Cov twj tso kua mis hauv qab saturated vapor siab yuav tsim cavitation.
Cavitation nyiaj pub dawb:
Txhawm rau tiv thaiv cavitation ntawm lub twj tso kua mis, lub zog ntxiv (siab) tus nqi ntxiv rau saum lub zog (siab) tus nqi ntawm cov kua nws nqus tau. Lub zog ntxiv no yog hu ua cavitation pub. Hauv cov khoom siv ntau lawm, nws yog ib qho ua kom nce siab ntawm cov kua ntawm qhov kawg ntawm lub twj tso kua mis, uas yog, siv lub siab zoo li qub ntawm cov kua kem ua lub zog ntxiv (siab), ntsuas hauv meters ntawm cov kua kem. Hauv kev siv cov tswv yim, muaj qhov tsim nyog cavitation pub NPSHr thiab cov txiaj ntsig zoo cavitation NPSHa.
1. Yuav tsum muaj cavitation nyiaj NPSHr
Lub essence yog tias lub siab poob ntawm cov kua xa los ntawm lub inlet ntawm lub twj tso kua mis yog txiav txim los ntawm lub twj tso kua mis nws tus kheej. Qhov tsawg dua tus nqi, qhov me dua qhov tsis kam ntawm lub twj tso kua mis inlet. Yog li ntawd, NPSHr yog qhov tsawg kawg nkaus tus nqi ntawm cavitation pub.
2. NPSHa zoo cavitation pub
The actual cavitation allowance obtained after the installation of the pump is determined by the installation conditions of the pump and is not related to the pump itself. The NPSHa value must be greater than NPSHr Generally, NPSHa>NPSHr+0.5m lossis ntau dua.
Cov yam ntxwv nruab nrab:
Nws hais txog cov yam ntxwv ntawm cov kua uas raug thauj. Nws yog ib qho tseem ceeb kom nkag siab txog qhov kub thiab txias ua haujlwm, qhov ceev (qhov tshwj xeeb lub ntiajteb txawj nqus), viscosity, seb nws puas yog cov kuab tshuaj organic, thiab seb nws puas tawg lossis lom.
1. Ua haujlwm kub
Kev ua haujlwm kub ntawm qhov nruab nrab muaj qhov cuam tshuam tseem ceeb rau kev xaiv lub twj tso kua mis, cuam tshuam ncaj qha rau cov cavitation pub, roj hmab thiab cov khoom siv sealing, thiab cov viscosity thiab lub ntiajteb txawj nqus ntawm qhov nruab nrab. Yog li thaum xaiv, nws yog ib qho tsim nyog yuav tsum paub qhov ua haujlwm kub ntawm qhov nruab nrab.
2. Qhov ntom ntom (specific gravity)
Qhov ntom ntom (qhov tshwj xeeb lub ntiajteb txawj nqus) muaj kev cuam tshuam rau Reynolds tus naj npawb ntawm cov khoom siv, qhov tsis kam ntawm cov kav dej, lub taub hau, thiab cuam tshuam ncaj qha rau lub zog ntawm lub twj tso kua mis. Qhov loj ntawm lub zog ncej yog ncaj qha proportional rau qhov ntom ntom (qhov tshwj xeeb lub ntiajteb txawj nqus)
3.viscosity
Lub viscosity (qhov tshwj xeeb lub ntiajteb txawj nqus) muaj kev cuam tshuam rau Reynolds tus naj npawb ntawm cov khoom, qhov tsis kam ntawm cov kav dej, lub taub hau, thiab ncaj qha cuam tshuam rau lub zog ntawm lub twj tso kua mis ncej. Nws kuj muaj feem xyuam rau kev xaiv lub twj tso kua mis. Vane twj tseem tsis tau tsim nyog rau kev xa cov viscosity siab tshaj tawm, thiab lub twj tso kua mis tsim nyog yuav tsum raug xaiv raws li qhov viscosity ntawm nruab nrab.
4. Yog tias qhov nruab nrab yog cov kuab tshuaj organic lossis cov xov xwm tawg, tawg - cov twj tso kua mis pov thawj yuav tsum tau xaiv rau lub twj tso kua mis, thiab cov roj hmab foob yuav tsum yog ua los ntawm cov khoom nruab nrab uas tiv taus cov kuab tshuaj organic (xws li FFKM, PTFE, thiab lwm yam)
Cim npe nrov: Khoom noj khoom haus qib centrifugal twj tso kua mis nrog qhib impeller rau siab txaus tus nqi, Tuam Tshoj, lwm tus neeg, manufacturers, hoobkas, nqe, ua nyob rau hauv Suav teb
