Ukucindezela igesi kuyinqubo yokusebenzisa amandla angaphandle ukuze kwenziwe amandla angase abe nomfutho wokuthola igesi, futhi i-compressor ingumsunguli wegesi ecindezelwe. Ngakho-ke, ukusebenza okuyisisekelo kwe-screw air compressor air end akuhlukaniseki kulezi zici ezine: ukucindezela, ukugeleza, amandla kanye namandla athile.
Ukusebenza okuyisisekelo kwe-screw air compressor air end - ingcindezi yomoya
Ukuthola amandla okucindezela umoya ocindezelwe kuyindlela eyisisekelo yokusebenza kwe-air compressor, futhi i-screw air compressor ayihlukile. I-screw air compressor air end yandisa ingcindezi yomoya ngokusebenzisa amandla angaphandle. Uma ingcindezi iphakeme, kulapho kusetshenziswa amandla amaningi, futhi kulapho izidingo zomoya ziphakama khona. Ngokuvamile sihlukanisa ama-air compressor ngezigaba ezine ngokuya ngengcindezi yokukhipha:
Ingcindezi ephansi: 0.2~1.0MPa Ingcindezi ephakathi: 1.0~10MPa Ingcindezi ephezulu: 10~100MPa Ingcindezi ephezulu kakhulu: ngaphezu kwe-100MPa
I-screw air compressor ivame ukuba nengcindezi yokukhipha engu-0.2 ~ 4.0MPa, okusho ukuthi ukusebenza kwayo, ukusebenziseka kwayo kanye nomnotho wayo kungcono kuleli banga. Lokhu kunqunywa yisakhiwo kanye nendlela yokusebenza ye-compressor air end, futhi futhi iyisigaba sengcindezi esinesidingo esikhulu semakethe.
Umfutho womoya ocindezelwe ohlinzekwa yi-air compressor ulinganiswa kakhulu ngesilinganiso somfutho, okuyisilinganiso somfutho wokukhipha i-Pd kumfutho wokudonsa i-Ps. Uma isilinganiso siphezulu, kulapho umfutho wokukhipha uphakama khona. ε=Pd/Ps Ifomula (6)
Kunesilinganiso sokucindezela kwangaphakathi kanye nesilinganiso sokucindezela kwangaphandle kwenjini eyinhloko ye-screw air compressor.
Isilinganiso sokucindezela kwangaphakathi: isilinganiso sokucindezela kumthamo wamazinyo phakathi kwenjini eyinhloko nomfutho wokumunca, okunqunywa indawo kanye nesimo sezimbobo zokumunca kanye nokukhipha umoya;
Isilinganiso sokucindezela kwangaphandle: isilinganiso sokucindezela epayipini lokukhipha umoya nengcindezi yokumunca. Izingcindezi zokumunca kanye nokucindezela kokukhipha umoya ezidingekayo ezimweni zokusebenza noma ukugeleza kwenqubo.
Uma isilinganiso sokucindezela kwangaphakathi ≠ isilinganiso sokucindezela kwangaphandle, injini eyinhloko izosebenzisa amandla amaningi; uma isilinganiso sokucindezela kwangaphakathi = isilinganiso sokucindezela kwangaphandle, injini eyinhloko isesimweni esihle kakhulu.
Ngenjini eyinhloko ye-screw air compressor, lapho injini eyinhloko, izinga lokushisa elizungezile, ingcindezi yokumunca, isivinini senjini eyinhloko nezinye izici zifana, lapho ingcindezi yokukhipha iphakama, kulapho ukusetshenziswa kwamandla kukhuphuka khona.
Ukusebenza okuyisisekelo kwe-screw air compressor air end - flow
Ukugeleza kuvame ukwakhiwa ukugeleza kobuningi kanye nokugeleza komthamo. Ezimisweni zomkhakha wohlelo lokucindezela umoya kanye nezindinganiso, sivame ukusebenzisa ukugeleza komthamo njengendlela yokulinganisa ukugeleza, okubizwa nangokuthi ivolumu yokukhipha noma ukugeleza kwegama lepuleti ezweni lakithi: ngaphansi kwengcindezi yokukhipha edingekayo, umthamo wegesi okhishwa yi-air compressor ngesikhathi seyunithi uguqulwa ube yisimo sokungenisa, okungukuthi, inani levolumu yengcindezi yokudonsa epayipini lokungenisa lesigaba sokuqala kanye nokushisa kokudonsa kanye nomswakama. Iyunithi yi-m3/min. Ukugeleza komthamo kuhlukaniswe ukugeleza komthamo wangempela kanye nokugeleza komthamo ojwayelekile.
Ngokuvamile, amasampula, izinketho, kanye nama-nameplate omshini asebenzisa ukugeleza kwevolumu okujwayelekile. Ngenxa yemboni, isifunda kanye nokusetshenziswa, ukugeleza kwevolumu okujwayelekile esidingweni semakethe yomoya ocindezelwe kunezincazelo ezimbili ngokuya ngomehluko esimweni esijwayelekile (izinga lokushisa, ingcindezi kanye nezingxenye):
Isimo esijwayelekile yingcindezi P=101.325KPa; izinga lokushisa elijwayelekile T=0℃; umswakama ohlobene ungu-0%. Kuvame ukutholakala kumadokhumenti egesi yezimboni, embonini yamakhemikhali noma ekubhideni, okubizwa ngokuthi “isikwele esijwayelekile”, ngokuvamile esinophawu “VN” kanye neyunithi engu-Nm3/min.
Isimo esijwayelekile yingcindezi P = 101.325KPa; izinga lokushisa elijwayelekile T = 20℃; umswakama ohlobene ngu-0%. Ngokuvamile kusetshenziswa ezindinganisweni zemboni yomoya ocindezelwe futhi ubizwa ngokuthi “izimo zokusebenza ezijwayelekile”. Uphawu luvame ukuba “V” kanti iyunithi ingu-m3/min.
Ngokuvamile, izinga lokugeleza kwevolumu elijwayelekile elisetshenziswa embonini yethu ye-air compressor yilona lokugcina. Ukuguqulwa kwezinga lokugeleza kwevolumu ngaphansi kwalezi zimo ezimbili kungabalwa ngefomula:
V(m3/min)=1.0732VN(Nm3/min) Ifomula (7)
Ngenjini eyinhloko ye-screw air compressor, ngaphansi kwezinye izimo ezifanayo, uma ibanga eliphakathi kwe-rotor likhulu, izinga lokugeleza kwevolumu yalo likhulu; uma ijubane lenjini eyinhloko liphakeme, izinga lokugeleza kwevolumu yalo likhulu.
Izinga lokugeleza kwevolumu ye-V = ivolumu yokucindezela injini enkulu ye-qv × isivinini sekhanda le-n Ifomula (8)
qv=CΨqv0Z1n=CΨCn1nλD3 Ifomula (9)
Lapho u-Z1——inani lamazinyo e-rotor yesilisa; n——isivinini se-rotor yesilisa; λ——isilinganiso se-rotor; D——ububanzi bangaphandle be-rotor yesilisa.
Ngakho-ke, ngenxa yokonga, sivame ukunciphisa izinhlobo zezinjini eziyinhloko futhi singalungisa ivolumu yokukhipha umoya we-air compressor ngokunquma isivinini senjini eyinhloko ukuze kuhlangatshezwane nesidingo semakethe.
Kodwa-ke, ijubane lenjini enkulu ye-screw compressor alikwazi ukuba phezulu kakhulu, ngokuvamile liphakathi kuka-800 no-10,000 rpm. Ngakho-ke, umenzi wenjini enkulu ye-screw wakha izinjini ezinkulu ezinebanga lokugeleza elihlukile ukuze kuhlangatshezwane nezidingo zokugeleza kwe-screw compressor.
Ngokuya ngokugeleza komoya okucindezelwe okuhlukahlukene, ama-air compressor angahlukaniswa kanje:
I-micro compressor<1m3>10～<100 m3min; large compressor ≥100 min
I-screw air compressor eyinhloko ifanelekela umshini owodwa one-1 ~ 100 m3/min, okuyindlela ethembeke kakhulu futhi engabizi kakhulu, futhi futhi iyimodeli eyinhloko emakethe ye-air compressor.
Uma ingcindezi iphakeme, ukusetshenziswa kwamandla kwenjini eyinhloko kuyanda; uma ukugeleza kwevolumu kukhulu, ukusetshenziswa kwamandla kwenjini eyinhloko kuyanda.
Uma inani lamandla athile enjini eyinhloko ye-screw air compressor lincane, ukusetshenziswa kwayo kwamandla kunciphisa futhi ukusebenza kwayo kwenjini eyinhloko kungcono. Ngaphansi kwesimo sokugeleza okungaguquki, lapho ingcindezi yokukhipha iphakama, amandla omgodi enjini eyinhloko aba maningi, ngakho-ke inani lamandla ayo athile likhula.
Injini ngayinye ye-screw air compressor inenani lamandla elithile elifanele, elihlobene nejubane lenjini enkulu. Uma ijubane lenjini enkulu liphansi kakhulu, ukuvuza kuyanda, umthamo wegesi uyancipha, futhi inani lamandla elithile liba phezulu; uma ijubane lenjini enkulu liphezulu kakhulu, ukungqubuzana kuyanda, amandla omgodi ayanda, futhi inani lamandla elithile liba phezulu. Kodwa kumele kube nejubane elifanele elenza inani lamandla elithile libe phansi kakhulu. Yingakho kungafanele ngempela ukusho ukuthi lapho injini enkulu inkulu, kulapho yonga khona amandla amaningi.
Uma siklama ama-screw air compressor kanye nama-variable frequency air compressor, ngenkathi siqinisekisa ikhwalithi, kumele futhi sicabangele umnotho, ukulinganisa kanye nokuguquguquka kwenjini eyinhloko. Ngakho-ke, sizosebenzisa ijika lamandla athile enjini eyinhloko ukuklama nokuthuthukisa ama-screw air compressor anezingcindezi nokugeleza okuhlukahlukene.
