Screw Compressor classification imagawidwa kukhala: yotsekedwa kwathunthu, yotsekedwa, yotsekeka, yotseguka yamtundu wa screw compressor. Monga mtundu wa rotary refrigeration compressor, screw compressor ili ndi mawonekedwe amtundu wa pistoni ndi mtundu wa mphamvu (mtundu wa liwiro).
1), poyerekeza ndi kubwereza pisitoni firiji kompresa, screw refrigeration kompresa ali ndi mndandanda wa ubwino monga kuthamanga, kulemera kwapang'ono, kakang'ono, phazi laling'ono komanso kutsika kwa mpweya.
2), compressor yamtundu wa firiji ilibe mphamvu yobwerezabwereza ya inertia, magwiridwe antchito abwino, magwiridwe antchito osalala, kugwedezeka pang'ono kwa chimango, maziko amatha kukhala ochepa.
3), wononga firiji kompresa kapangidwe ndi osavuta, chiwerengero cha zigawo zazing'ono, palibe kuvala mbali ngati valavu, mphete pisitoni, mbali zake zazikulu mikangano monga rotor, kubala, etc., mphamvu ndi kuvala kukana ndizokwera kwambiri, ndipo zinthu zokometsera ndi zabwino, kotero kuchuluka kwa processing ndi kochepa, kugwiritsira ntchito zinthu kumakhala kochepa, kuyendayenda kwa ntchito ndiutali, kugwiritsa ntchito kumakhala kodalirika, kukonza kosavuta, kumathandiza kukwaniritsa zoyendetsa zokha.
4) Poyerekeza ndi compressor liwiro, wononga kompresa ali ndi makhalidwe kukakamiza gasi kufala, ndiye kuti, voliyumu utsi pafupifupi osakhudzidwa ndi kuthamanga utsi, chodabwitsa opareshoni sikuchitika mu voliyumu yaing'ono utsi, ndi mkulu dzuwa. ikhoza kusungidwabe m'malo osiyanasiyana ogwira ntchito.
5), kugwiritsa ntchito slide valve kusintha, kumatha kukwaniritsa mphamvu zopanda mphamvu.
6), screw compressor sichimakhudzidwa ndi kumwa kwamadzimadzi, mutha kugwiritsa ntchito kuziziritsa kwa jakisoni wamafuta, kotero pansi pa chiwopsezo chofanana, kutentha kwamadzi kumakhala kotsika kwambiri kuposa mtundu wa pistoni, kotero kuti chiwopsezo cha gawo limodzi ndichokwera.
7), palibe voliyumu yovomerezeka, kotero mphamvu ya voliyumu ndiyokwera kwambiri.
Mapangidwe a screw compressor ndi zida zoyendera mafuta, zosefera zoyamwa, valavu yoyang'ana, chipangizo choteteza makina ndi kuwongolera mphamvu kuziziritsa.
(1) Zida zoyendera mafuta
Zimaphatikizapo cholekanitsa mafuta, fyuluta yamafuta, chotenthetsera mafuta, mulingo wamafuta.
(2) Fyuluta yoyamwa
Amagwiritsidwa ntchito kuthetsa zonyansa pakati kuti ateteze ntchito yachibadwa ya ma valve ndi zipangizo. Pamene madzimadzi amalowa mu katiriji fyuluta ndi kukula kwake fyuluta nsalu yotchinga, zosafunika wake oletsedwa, ndi filtrate woyera amatulutsidwa kudzera fyuluta kubwereketsa.
(3) Chongani valavu
Imani kuti muteteze mpweya wothamanga kwambiri kuti usabwerere ku kompresa kuchokera ku condenser, kuti muteteze kugunda kwapambuyo kwa kompresa ndikusintha kwa rotor.
(4) Chipangizo choteteza dongosolo
Kuwunika kwa kutentha kwa mpweya: kusowa kwa mafuta kumayambitsa kukwera kwadzidzidzi kutentha kwa mpweya, gawo la chitetezo chamagetsi likhoza kuyang'anira kutentha kwa mpweya.
Pressure difference switch HP/LP: gwiritsani ntchito kuthekera kwake kozimitsa kuwongolera, kuti muwonetsetse kuti zida zitha kutsekedwa munthawi yake pansi pazida zodzitchinjiriza zosakhazikika.
Kuwongolera mulingo wamafuta: Ndikofunikira kugwiritsa ntchito chowunikira chamafuta kuti muwongolere mosamalitsa kuchuluka kwamafuta pamagwiritsidwe awa (makonzedwe a mapaipi aatali, makonzedwe akutali a condenser)
(5) Kuzizira mphamvu kulamulira
Malinga ndi kuzizira kwa 100-75-50-25% kusintha, slide block ili ndi malo 4 ofanana, slide block imalumikizidwa mwachindunji ndi slide valve ikuyenda mu silinda ya hydraulic, malo a slide valve amayendetsedwa ndi valavu solenoid mawonekedwe enieni a valavu ya slide kusintha doko loyamwa.
