Lai sasniegtu \u0161\u0137idrumu transport\u0113\u0161anas m\u0113r\u0137i, tie izmanto vair\u0101ku fiks\u0113ta tilpuma padeves vien\u012bbu periodisku p\u0101rveido\u0161anu darba kamer\u0101.<\/p>\n

Centrb\u0113dzes s\u016bk\u0146a darb\u012bbas princips ir centrb\u0113dzes kust\u012bba. Centrb\u0113dzes kust\u012bba faktiski ir objekta inerces izpausme. Piem\u0113ram, kad \u016bdens pilieni uz lietussarga l\u0113ni rot\u0113, \u016bdens pilieni rot\u0113 kop\u0101 ar lietussargu. Tas notiek t\u0101p\u0113c, ka berze starp lietussargu un \u016bdens pilieniem darbojas k\u0101 \u016bdens pilienu virzes sp\u0113ks. Tom\u0113r, ja lietussargs grie\u017eas \u0101tr\u0101k, berzes sp\u0113ks nav pietiekams, lai \u016bdens pilieni kust\u0113tos ri\u0146\u0137veid\u012bgi. Tad \u016bdens pilieni atdal\u012bsies no lietussarga un p\u0101rvietosies uz \u0101r\u0113jo malu, glu\u017ei t\u0101pat k\u0101 ar virves pal\u012bdz\u012bbu velkot akmeni, lai veiktu ap\u013cveida kust\u012bbu. Ja \u0101trums b\u016bs p\u0101r\u0101k liels, virve p\u0101rtr\u016bks un akmens izlidos \u0101r\u0101. T\u0101 ir t\u0101 saukt\u0101 centrb\u0113dzes kust\u012bba.<\/p>\n

Centrb\u0113dzes s\u016bknim darbojoties, \u0101tri rot\u0113jo\u0161\u0101s l\u0101psti\u0146as virzu\u013ca l\u0101psti\u0146as virza \u0161\u0137idrumu un izmet \u0161\u0137idrumu \u0101r\u0101, t\u0101d\u0113j\u0101di sasniedzot transport\u0113\u0161anas m\u0113r\u0137i.

Kad l\u0101psti\u0146rati strauji grie\u017eas, l\u0101psti\u0146as liek \u0161\u0137idrumam strauji griezties. Rot\u0113jo\u0161ais \u0161\u0137idrums centrb\u0113dzes sp\u0113ka ietekm\u0113 izlec no l\u0101psti\u0146rite\u0146a. P\u0113c tam, kad \u0161\u0137idrums s\u016bkn\u012b ir izmests \u0101r\u0101, l\u0101psti\u0146rite\u0146a centr\u0101 veidojas vakuuma zona. Atmosf\u0113ras spiediena ietekm\u0113 \u0101r\u0113jais \u0161\u0137idrums caur cauru\u013cu t\u012bklu tiek iespiests \u016bdens iepl\u016bdes caurul\u0113, un var pan\u0101kt nep\u0101rtrauktu transport\u0113\u0161anu.<\/p>\n

3 Skr\u016bves s\u016bknis<\/p>\n

Skr\u016bves s\u016bknis ir jauna tipa s\u016bknis, kas darbojas p\u0113c rot\u0101cijas principa. Galven\u0101s darba da\u013cas ir ekscentrisk\u0101 skr\u016bve (rotors) un fiks\u0113t\u0101 bukse (stators). Pateicoties abu da\u013cu \u012bpa\u0161ajai \u0123eometriskajai formai, veidojas atsevi\u0161\u0137as herm\u0113tiskas kameras. Vide tiek virz\u012bta un pl\u016bst vienm\u0113r\u012bgi aksi\u0101l\u0101 virzien\u0101, iek\u0161\u0113j\u0101s pl\u016bsmas \u0101trums ir neliels, tilpums paliek nemain\u012bgs, un spiediens ir stabils, t\u0101p\u0113c nerodas virpu\u013cstr\u0101vas un mais\u012bjumi.<\/p>\n

Turkl\u0101t skr\u016bves s\u016bk\u0146iem ir \u0161\u0101das priek\u0161roc\u012bbas:
\n1) Pla\u0161s spiediena un pl\u016bsmas diapazons. Spiediens ir aptuveni 3,4-340 kg*N\/c\u33a1, un pl\u016bsmas \u0101trums var sasniegt 300-3000 kubikmetru;
\n2) pla\u0161s transport\u0113jamo \u0161\u0137idrumu veidu un viskozit\u0101tes diapazons;
\n3) T\u0101 k\u0101 s\u016bk\u0146a rot\u0113jo\u0161o da\u013cu inerces sp\u0113ks ir neliels, var izmantot \u013coti lielu \u0101trumu;
\n4) Laba s\u016bkn\u0113\u0161anas veiktsp\u0113ja un sp\u0113c\u012bga pa\u0161s\u016bkn\u0113\u0161anas sp\u0113ja;
\n5) Vienm\u0113r\u012bga un nep\u0101rtraukta pl\u016bsma, maza vibr\u0101cija, zems trok\u0161\u0146a l\u012bmenis un ilgs kalpo\u0161anas laiks;
\n6) Sal\u012bdzinot ar citiem rot\u0101cijas s\u016bk\u0146iem, tas ir maz\u0101k jut\u012bgs pret ien\u0101ko\u0161o g\u0101zi un net\u012brumiem;
\n7) Ciet\u0101 konstrukcija un vienk\u0101r\u0161a uzst\u0101d\u012b\u0161ana un apkope.<\/p>\n

\n2) rotora s\u016bknis ir maza izm\u0113ra, viena tre\u0161da\u013ca no viena skr\u016bves s\u016bk\u0146a uzst\u0101d\u012b\u0161anas plat\u012bbas, samazinot in\u017eeniertehnisko b\u016bvdarbu apjomu un izmaksas.
\n3) Rotora s\u016bkni var remont\u0113t tie\u0161saist\u0113, nedemont\u0113jot cauru\u013cvadu, kas ir \u0113rti un \u0101tri, samazinot d\u012bkst\u0101ves laiku.
\n4) rotora s\u016bk\u0146a neekstr\u016bzijas darba princips un regul\u0113jam\u0101 korpusa konstrukcija pagarina kalpo\u0161anas laiku, samazina apkopes laiku un ietaupa rezerves da\u013cu izmaksas.<\/p>\n

2. Skr\u016bves s\u016bk\u0146a un centrb\u0113dzes s\u016bk\u0146a sal\u012bdzin\u0101jums
\n1) Kad s\u016bk\u0146a dobum\u0101 non\u0101k g\u0101ze, centrb\u0113dzes s\u016bknis darbojas \u013coti nestabili, efektivit\u0101te iev\u0113rojami samazin\u0101s, s\u016bknis \u013coti vibr\u0113, un kavit\u0101cija ir nopietna. Skr\u016bves s\u016bknis var labi realiz\u0113t jauktu g\u0101zes, \u0161\u0137idruma un cietas vielas transport\u0113\u0161anu.
\n2) Centrb\u0113dzes s\u016bk\u0146a \u0101trums parasti ir \u013coti liels, l\u012bdz pat t\u016bksto\u0161iem apgriezienu min\u016bt\u0113, un barotnes nob\u012bdes \u012bpa\u0161\u012bba ir \u013coti liela; skr\u016bves s\u016bknis parasti darbojas ar mazu \u0101trumu, lai nodro\u0161in\u0101tu, ka nav impulsu un vibr\u0101ciju, un nodro\u0161in\u0101tu transport\u0113\u0161anu bez nob\u012bdes.
\n3) Ja centrb\u0113dzes s\u016bkni izmanto mediju transport\u0113\u0161anai, kad medijs k\u013c\u016bst viskozs, pl\u016bsmas \u0101trums vai spiediens strauji samazin\u0101s. Skr\u016bves s\u016bknis ir piem\u0113rot\u0101ks mediju ar augstu viskozit\u0101ti un augstu cietvielu saturu transport\u0113\u0161anai.<\/p>\n
