Micro twj
Micropumps yog cov khoom siv uas tuaj yeem tswj thiab tswj cov dej me me ntawm cov kua / roj. Txawm hais tias txhua yam ntawm cov twj me me ntawm kev ua lag luam feem ntau hu ua micro twj, vim hais tias lub npe muaj tseeb dua yog lub twj tso kua mis uas txwv rau qhov ntau ntawm millimeters thiab centimeters. Cov twj tso kua mis no tau nyiam tshwj xeeb hauv kev tshawb fawb ntawm microfluidics. Nyob rau hauv xyoo tas los no, nws tau siv dav hauv kev lag luam, khoom siv hauv tsev, thiab cov khoom lag luam niam thiab menyuam. Piv nrog rau cov twj micro uas twb muaj lawm, lawv qhov loj me me tag nrho, cov nqi peev xwm thiab kev ntsuas qhov tseeb siab dua tau ua rau muaj kev txaus siab rau lub twj tso kua mis tshiab no.
Ntawm lawv, micro twj tuaj yeem muab faib ua:
1. Diaphragm micro twj siv rov tsav tsheb ntawm lub diaphragm tsav cov kua dej. Lub membrane yog nyob rau saum lub ntsiab twj tso kua mis valve, uas yog nyob nruab nrab ntawm lub inlet thiab qhov hluav taws xob microvalves. Thaum lub membrane yog deflected upwarded los ntawm ib co tsav tsheb, cov kua yog rub mus rau hauv lub inlet valve mus rau lub ntsiab twj tso kua mis valve. Tom qab ntawd lub membrane yog qis dua thiab cov kua dej tawm los ntawm lub qhov hluav taws xob valve. Rov ua cov txheej txheem no kom cov kua dej tsis tu ncua, Siv SC4001PPM (SC5002PM) lub tshuab nqus tsev diaphragm ua piv txwv
2. Piezoelectric micro twj yog ib hom piston reciprocating diaphragm twj tso kua mis. Piezoelectric-tsav micropumps cia siab rau cov khoom siv hluav taws xob ntawm piezoelectric ceramics kom deform nyob rau hauv teb rau ib qho kev siv hluav taws xob. Lub piezoelectric disc txuas rau daim nyias nyias ua rau lub diaphragm deflect nyob rau hauv lub tsav ntawm sab nraud axial hluav taws xob teb, yog li ua rau lub chamber ntawm lub micropump nthuav thiab cog lus.
3. Lub peristaltic micropump yog ib lub micropump uas muaj tsawg kawg yog peb microvalves nyob rau hauv series. Peb lub li qub no qhib thiab kaw ua ntu zus los rub cov kua dej los ntawm qhov nkag mus rau qhov hluav taws xob hauv cov txheej txheem hu ua peristalsis
Daim ntawv thov teb
Micropumps muaj peev xwm siv tau hauv kev lag luam, xws li xa me me ntawm cov kua nplaum thaum lub sijhawm tsim khoom, thiab kev siv tshuaj biomedical, suav nrog cov khoom xa tuaj lossis cov tshuaj xa tuaj.
