Mapampu amtundu wa mphete yamadzi a SZ ndi ma compressor amagwiritsidwa ntchito kupopa kapena kupondereza mpweya ndi mpweya wina wosawononga komanso wosasungunuka m'madzi wopanda tinthu tating'onoting'ono, kuti apange vacuum ndi kupanikizika mkati mwa chidebe chotsekedwa.Koma mpweya woyamwa amalola osakaniza pang'ono madzi, Iwo ankagwiritsa ntchito.m'makina, petrochemical, pharmaceuticals, chakudya, kupanga shuga ndi zamagetsi.
Monga m'kati mwa ntchito, psinjika ya gasi ndi isothermal, palibe chiopsezo chilichonse pa kukanikiza ndi kupopa mpweya woyaka ndi kuphulika, kuwapangitsa kukhala ovomerezeka kwambiri.
mfundo yogwirira ntchito ya pampu yamtundu wa SZ yamadzi amphete:
Pampu ya vacuum yamadzi ya SZ ikuwonetsedwa mu Chithunzi 1. Choyimitsa ① chimayikidwa mozungulira mu thupi la mpope ②, ndipo utali wina wamadzi umalowetsedwa mu mpope poyambira.
Choncho, pamene gudumu la vaneni likuzungulira, madzi amakhudzidwa ndi mphamvu ya centrifugal kuti apange mphete yamadzi yozungulira pa khoma la thupi la mpope ③, pamwamba pamadzi amkati mwa mphete yamadzi ndi tangent ku likulu, ndipo amazungulira njira yaikulu ya muvi.Pakutembenuka kwa theka loyamba, mphete yamadzi Yamkati imasiyanitsidwa pang'onopang'ono ndi likulu, kotero mpope wamadzi wa SZ umapanga malo pakati pa masamba opangira mpweya ndipo pang'onopang'ono umakula, kotero kuti mpweya umalowetsedwa pa doko loyamwa;pozungulira theka lachiwiri, mkati mwa mphete yamadzi pang'onopang'ono imayandikira malo, Kuchuluka kwa danga pakati pa masamba kumachepetsedwa, ndipo mpweya pakati pa masambawo umakanizidwa ndikutulutsidwa.
Mwanjira iyi, nthawi iliyonse choyikapo chizungulira, kuchuluka kwa danga pakati pa masambawo kumasintha kamodzi, ndipo madzi pakati pa tsamba lililonse amabwereranso ngati pisitoni, ndipo mpope wamadzi wa SZ wamadzimadzi umayamwa gasi mosalekeza.
Popeza madzi amatenthedwa panthawi ya ntchito, ndipo gawo lina la madzi lidzatulutsidwa pamodzi ndi mpweya, kotero mpope wamadzi wa SZ uyenera kuperekedwa mosalekeza ndi madzi ozizira kuti ukhale woziziritsa ndi kubwezeretsanso madzi omwe amagwiritsidwa ntchito pompani panthawi yogwira ntchito.Madzi ozizira omwe amaperekedwa makamaka ndi 15 ° C.
Pamene mpweya kutulutsidwa ndi SZ madzi mphete vacuum mpope ndi mpweya utsi, thanki madzi chikugwirizana ndi utsi mapeto.Gasi wotulutsa mpweya ndi gawo lina la madzi omwe amanyamula atayidwa mu thanki yamadzi, gasiyo amathamangira ku chitoliro cha tanki yamadzi, ndipo madzi amagwera mu thanki yamadzi.Pansi pake amabwereranso ku mpope kudzera mu chitoliro chobwerera.Ngati nthawi yozungulira ndi yayitali, imatulutsa kutentha.Panthawiyi, madzi ozizira amayenera kuperekedwa kuchokera kumadzi a tanka yamadzi.

Chithunzi chojambula cha pampu ya mphete yamadzi ya vacuum ndi compressor
Popeza madzi kutenthetsa pa ntchito, ndi mbali ya madzi adzatulutsidwa pamodzi ndi mpweya, kotero SZ madzi mphete zingalowe mpope ayenera mosalekeza kupereka madzi ozizira pa ntchito kuziziritsa ndi kuwonjezera madzi ankadya mpope.
Pamene mpweya kutulutsidwa ndi SZ madzi mphete vacuum mpope ndi mpweya utsi, thanki madzi chikugwirizana ndi utsi mapeto.Pambuyo pa madzi otayira ndi gawo la thanki yamadzi, gasiyo amathamangira paipi yotulutsira madzi a thanki yamadzi, ndipo madzi amagwera pansi pa thanki yamadzi.Chitoliro chobwerera chimabwereranso ku mpope kuti chigwiritsidwe ntchito.Ngati madzi azungulira kwa nthawi yayitali, amatulutsa kutentha.Panthawiyi, madzi ozizira amayenera kuperekedwa kuchokera kumadzi a tanka yamadzi.
Pamene mpope wamadzi wa SZ ukugwiritsidwa ntchito ngati compressor, cholekanitsa madzi a gasi chiyenera kugwirizanitsidwa ndi mapeto a mpweya.Pamene mpweya wokhala ndi madzi umalowa mu olekanitsa, udzasiyanitsidwa, ndipo kutuluka kwa mapiri olekanitsa gasi kudzatumizidwa kumalo kumene kumafunika, pamene madzi otentha Amatulutsidwa kudzera muzitsulo zodziwikiratu.(N'zosavuta kutenthetsa pamene gasi wapanikizidwa, ndipo madzi amakhala madzi otentha akatuluka pampopi), mpope wamadzi wa SZ wamadzimadzi ayeneranso kupereka madzi ozizira pansi pa olekanitsa kuti awonjezere zomwe zatulutsidwa. madzi otentha, ndipo panthawi imodzimodziyo amagwira ntchito yozizira .
