Mfundo Yogwirira Ntchito ya Roots Vacuum Pump

Pampu ya vacuum ya mizuimatanthawuza pampu ya vacuum yosinthika yokhala ndi zozungulira ziwiri zooneka ngati tsamba zomwe zimazungulira molumikizana mbali zosiyana. Pali kusiyana kochepa pakati pa ma rotors ndi pakati pa ma rotor ndi khoma lamkati la pompano popanda kukhudzana wina ndi mzake. Kusiyana kwakukulu ndi 0.1 mpaka 0.8 mm; Palibe mafuta odzola amafunikira. Mbiri ya rotor imaphatikizapo mizere ya arc, mizere ya involute, ndi ma cycloids. Kuchuluka kwa voliyumu yogwiritsira ntchito pampu ya involute rotor ndi yayikulu ndipo kulondola kwa makina ndikosavuta kutsimikizira, kotero mawonekedwe a rotor nthawi zambiri amakhala amtundu wa involute.

Mfundo yogwira ntchito ya aPampu ya vacuum ya mizundi zofanana ndi za Roots blower. Chifukwa cha kusinthasintha kosalekeza kwa rotor, mpweya wopopera umalowetsedwa mu danga la v0 pakati pa rotor ndi chipolopolo cha mpope kuchokera ku mpweya wolowera mpweya, ndiyeno amatulutsidwa kudzera pa doko lotulutsa mpweya. Popeza malo a v0 amatsekedwa kwathunthu pambuyo pokoka mpweya, palibe kuponderezana kapena kukulitsa gasi mu chipinda chopopera. Koma pamene pamwamba pa rotor imazungulira m'mphepete mwa doko lotulutsa mpweya ndipo danga la v0 likugwirizanitsidwa ndi mbali yotulutsa mpweya, chifukwa cha kupanikizika kwakukulu kwa gasi kumbali yotulutsa mpweya, mpweya wina umathamangira ku danga la v0, kuchititsa kuthamanga kwa gasi kuti kuchuluke mwadzidzidzi. Pamene rotor ikupitirizabe kusinthasintha, mpweya umatulutsidwa pampope.
