I-Positive displacement compressor ithatha inani elithile legesi noma umoya, bese ikhuphula ingcindezi yegesi ngokucindezela ivolumu yesilinda esivaliwe.Ivolumu ecindezelweyo itholakala ngokuhamba kwengxenye eyodwa noma ngaphezulu yokusebenza ngaphakathi kwe-compressor block.
i-piston compressor
I-compressor ye-piston ingeyokuqala eyakhiwe futhi iyi-compressor evamile kakhulu kuma-compressor ezimboni.Inokusebenza okukodwa noma okuphindwe kabili, okugcotshwe ngamafutha noma ayinawo uwoyela, futhi inani lamasilinda lihlukile ekucushweni okuhlukile.Ama-compressor e-Piston awahlanganisi kuphela ama-compressor amancane ama-cylinder aqondile, kodwa futhi ama-compressor amancane amise okwe-V, okuyiwona avame kakhulu.
i-piston compressor
Phakathi kwama-compressor amakhulu asebenza kabili, uhlobo lwe-L lunesilinda esivundlile esinengcindezi ephansi kanye nesilinda esivundlile sokucindezela okuphezulu.Le compressor inikeza izinzuzo eziningi futhi isiphenduke umklamo ovame kakhulu.
Ama-compressor agcotshwe ngamafutha adinga ukugcotshwa kwe-splash noma ukugcotshwa kwengcindezi ukuze kusebenze okuvamile.Ama-compressor amaningi anama-automatic valves.Ukuvulwa nokuvalwa kwe-valve ephathwayo kubonakala ngomehluko wokucindezela ezinhlangothini zombili ze-valve.
I-piston compressor engenawo uwoyela
Ama-piston compressor angenawo uwoyela anezindandatho ze-piston ezenziwe nge-Teflon noma i-carbon, noma, afana ne-labyrinth compressors, izindonga ze-piston ne-cylinder zikhubazekile (zinamazinyo).Imishini emikhulu ifakwe ama-cross couplings nama-gaskets ezikhonkwaneni zokuphotha, kanye nokufaka umoya omncane ukuvimbela uwoyela ovela ku-crankcase ukuthi ungangeni egumbini lokucindezela.Ama-compressor amancane avame ukuba nama-bearings ku-crankcase avalwe unomphela.
I-piston compressor ifakwe uhlelo lwe-valve, oluqukethe amasethi amabili amapuleti ensimbi engenasici.Iphistoni liya phansi, limunca umoya kusilinda, futhi ipuleti levalvu elikhulu kunawo wonke liyanwebeka futhi ligoqele phansi, livumele umoya ukuba udlule.Ipiston iya phezulu, futhi ipuleti levalvu elikhudlwana liyagoqa futhi likhuphuke, livale isihlalo sevalvu ngesikhathi esifanayo.Isenzo se-telescoping sediski ye-valve encane sibe sesiphoqa umoya ocindezelwe ngembobo esesihlalweni sevalvu.
I-labyrinth-sealed, i-piston compressor engenawoyela esebenza kabili eneziphambano.
I-compressor ye-diaphragm
Ama-compressor e-diaphragm anqunywa izici zawo zesakhiwo.Ama-diaphragm awo asebenza ngomshini noma nge-hydraulically.Ama-compressor we-diaphragm wemishini asetshenziswa ekugelezeni okuncane, ukucindezela okuphansi noma amaphampu e-vacuum.I-hydraulic diaphragm compressors isetshenziselwa ukucindezela okuphezulu.
I-crankshaft evamile ku-compressor ye-diaphragm eyimishini idlulisa ukunyakaza okuphindaphindiwe ngezinduku zokuxhuma ku-diaphragm
I-compressor ephindwe kabili
Ukuthuthukiswa kwe-twin-screw rotary positive compressor displacement ihlehlela emuva kuma-1930s, lapho kwakunesidingo sokugeleza okuphezulu, ukugeleza okuqinile kwe-rotary compressor ekwazi ukushintsha izingcindezi.
Ingxenye eyinhloko ye-twin-screw element iyi-rotor yesilisa kanye ne-rotor yesifazane, kuyilapho ijikeleza ngendlela ehlukile, ivolumu phakathi kwabo nezindlu iyancipha.Isikulufu ngasinye sinesilinganiso esigxilile, esakhelwe ngaphakathi sokuminyanisa, esincike kubude besikulufu, ukuphakama kwamazinyo esikulufu kanye nokuma kwembobo yokukhipha umoya.Ukuze usebenze kahle kakhulu, isilinganiso sokucindezela esakhelwe ngaphakathi kufanele sihambisane nengcindezi yokusebenza edingekayo.
Ama-screw compressor ngokuvamile awanawo ama-valve futhi awekho amandla emishini abangela ukungalingani.Okusho ukuthi, ama-screw compressor angasebenza ngesivinini esiphezulu se-shaft futhi ahlanganise amazinga aphezulu okugeleza kwegesi nobukhulu obuncane bangaphandle.Amandla e-axial ancike kumehluko wengcindezi phakathi kokungena nokukhipha, kumele akwazi ukunqoba amandla okuthwala.
