I-Screw air compressors ziicompressor ezilungileyo zokufuduka, ezifezekisa injongo yoxinzelelo lwegesi ngokuncipha kancinci komthamo wokusebenza.
Umthamo wokusebenza we-screw air compressor uqulunqwe ngamabini ee-rotors ezibekwe ngokuhambelana omnye komnye kwaye zibandakanya kunye kunye ne-chassis evumela le peri ye-rotors.Xa umatshini usebenza, amazinyo e-rotors ezimbini zifakwe kwi-cogs zomnye, kwaye njengoko i-rotor ijikeleza, amazinyo afakwe kwi-cog yomnye ahamba ukuya ekupheleni kwe-exhaust, ukuze umthamo ovalelwe ngamazinyo welinye uhle ngokuthe ngcembe, kwaye uxinzelelo luyanda ngokuthe ngcembe de kufike uxinzelelo olufunekayo.Xa uxinzelelo lufikeleleke, ii-cogs zinxibelelana ne-exhaust port ukuze zifezekise ukukhupha.
Emva kokuba i-alveolar ifakwe ngamazinyo omchasi asebenzisana nayo, izithuba ezibini ezihlulwe ngamazinyo zenziwe.I-alveolar kufuphi nesiphelo sokufunxa ngumthamo wokufunxa, kwaye lowo usondele ekupheleni kokukhupha ngumthamo wegesi ecinezelweyo. Ngokusebenza kwe-compressor, amazinyo e-rotor echasayo afakwe kwi-cogging ahamba ukuya ekupheleni kokukhupha, ngoko. ukuba umthamo wokufunxa uyaqhubeka nokwandisa kunye nomthamo wegesi ecinezelekileyo uyaqhubeka nokuncipha, ngaloo ndlela uqaphela inkqubo yokufunxa kunye noxinzelelo kwi-cogging nganye.Xa uxinzelelo lwegesi yegesi ecinezelweyo kwi-cogging ifikelela kuxinzelelo olufunekayo lokukhupha, i-cogging inxibelelana nje ne-vent kunye nenkqubo yokukhupha iqala. ziphindaphindwa, ukwenzela ukuba i-compressor ikwazi ukuphefumla ngokuqhubekayo, icinezele kwaye ikhuphe.
Umgaqo wokusebenza kunye nesakhiwo se-screw compressor:
1. Inkqubo yokufunxa: Izibuko lokufunxa kwicala lokungenisa lohlobo lwe-screw kufuneka liyilwe ukuze igumbi lokucinezela libe nokuphefumlelwa ngokupheleleyo.I-compressor yomoya yodidi lwe-screw ayinalo iqela levalvu yokungena kunye ne-exhaust.Ukungeniswa kulungelelaniswa kuphela ngokuvula nokuvalwa kwevalve yokulawula.Xa i-rotor ijikeleza, isithuba se-toove groove ye-rotor engundoqo kunye ne-rotor encedisayo idluliselwe kwi-air intake ekupheleni kodonga lokuvula, isithuba z * sikhulu, ngeli xesha isithuba se-oth groove se-rotor sinxibelelana nomoya okhululekile womoya. i-inlet, ngenxa yokuba wonke umoya kwi-tooth groove ikhutshwe ngexesha lokukhupha, kwaye i-toove groove ikwimeko yokucima ekupheleni kokukhupha.Xa ikhutshelwa kwindawo yokungenisa umoya, isithuba z* sikhulu.Ngeli xesha, indawo yezinyo le-rotor inxibelelana nomoya okhululekile wokungena emoyeni, kuba wonke umoya kwi-toove groove ukhutshwa ngexesha lokukhupha.Ekupheleni kokukhupha, i-toove groove ikwimeko ye-vacuum.Xa idluliselwe kwi-air inlet, Umoya wangaphandle ufunxwa kwaye uhamba nge-axially kwi-groove yezinyo ye-rotors engundoqo kunye neyoncedo. Icala lokungena komoya le-rotor lijikiwe kwi-air inlet ye-chassis, kwaye umoya ophakathi kwee-grooves zamazinyo uvaliwe.
2. Ukutywinwa kunye nenkqubo yokuhambisa: Ekupheleni kwe-suction ye-rotors eziphambili kunye ne-axiliary, i-toove groove ye-rotors eziphambili kunye ne-axiliary rotors kunye ne-chassis ivaliwe.Ngeli xesha, umoya uvaliwe kwi-oth groove kwaye awusaphumi ngaphandle, oko kukuthi, [inkqubo yokutywinwa].Ii-rotors ezimbini ziyaqhubeka zijikeleza, kwaye iincopho zazo zamazinyo kunye nezinyo zihambelana ekupheleni kokufunxa, kunye nomphezulu we-anastomosis. ngokuthe ngcembe iqhubela phambili ukuya ekupheleni kokuphuma.
3. Inkqubo yokunyanzeliswa kunye ne-oyile yokutofa: Ngexesha lenkqubo yokuhambisa, umphezulu we-meshing uhamba ngokuthe ngcembe ukuya ekupheleni kokukhupha, oko kukuthi, i-toove groove phakathi kwe-meshing surface kunye ne-exhaust port iyancipha ngokuthe ngcembe, kwaye igesi kwi-toove groove iyancipha ngokuthe ngcembe. kwaye uxinzelelo luyanda.Le yi [inkqubo yokuxinzelela] .Ngexesha elifanayo nokunyanzeliswa, ioli yokuthambisa iphinda itshizwe kwigumbi loxinzelelo kwaye ixutywe kunye negesi yegumbi ngenxa yokwahlukana koxinzelelo.
4. Inkqubo yokukhupha: Xa isiphelo se-meshing sobuso be-screw air compressor i-rotor yokugcina idluliselwe ukunxibelelana nokuphuma kwe-chassis, (ngeli xesha uxinzelelo lwegesi ecinezelweyo yi-z * phezulu) igesi ecinezelekileyo iqala ukukhutshwa. de umphezulu we-meshing wencopho yezinyo kunye ne-toove groove ihanjiswe ebusweni bombhobho wokuphuma.Ngeli xesha, indawo ye-toove groove phakathi kwe-meshing surface ye-rotors ezimbini kunye ne-port yokukhupha i-chassis yi-zero, oko kukuthi, (inkqubo yokukhupha) igqityiwe.Kwangaxeshanye, ubude bombhobho wamazinyo phakathi komphezulu we-meshing we-rotor kunye ne-air inlet ye-chassis ifikelela ku-z * ubude, kwaye inkqubo yokufunxa iyaqhubeka.
I-Screw air compressors yahlulwe ibe: uhlobo oluvulekileyo, uhlobo oluvaliweyo, uhlobo oluvalwe ngokupheleleyo
1. I-screw compressor evalelwe ngokupheleleyo: umzimba uthatha umgangatho ophezulu, i-low-porosity cast iron structure kunye ne-thermal deformation encinci;umzimba wamkela isakhiwo sodonga oluphindwe kabini kunye nesicatshulwa sokukhupha, amandla aphezulu kunye nefuthe elihle lokunciphisa ingxolo;imikhosi yangaphakathi nangaphandle yomzimba ilungelelene ngokusisiseko, kwaye akukho mngcipheko woxinzelelo oluphezulu oluvulekileyo kunye ne-semi-enclosed;igobolondo iyisakhiwo sentsimbi esinamandla amakhulu, imbonakalo entle kunye nobunzima obulula.Isakhiwo esithe nkqo samkelwa, kwaye i-compressor ithatha indawo encinci, ehambelana nokucwangciswa kweentloko ezininzi ze-chiller;i-bearing ephantsi ifakwe kwi-tank yeoli, kwaye ukuthwala kufakwe kakuhle;i-axial force ye-rotor iyancitshiswa ngama-50% xa kuthelekiswa nohlobo oluvaliweyo kunye noluvulekileyo (umphumo wokulinganisa we-motor shaft kwicala lokukhupha);akukho mngcipheko we-horizontal motor cantilever, ukuthembeka okuphezulu;thintela impembelelo ye-screw rotor, ivalve ye-spool, kunye nobunzima be-motor rotor ekuchanekeni okuhambelanayo, kunye nokuphucula ukuthembeka;inkqubo yokuhlanganisa kakuhle.Uyilo oluthe nkqo lwe-screw ngaphandle kwempompo yeoli yenza ukuba i-compressor iqhube okanye imise ngaphandle kokunqongophala kweoli.I-bearing ephantsi ifakwe kwitanki yeoli iyonke, kwaye i-high beararing ithatha uxinzelelo oluhlukeneyo lokunikezelwa kweoli;iimfuno zoxinzelelo lwenkqubo eyahlukileyo ziphantsi.Kwimeko yongxamiseko, umsebenzi wokukhusela i-lubrication yokuthwala ukuphepha ukungabikho kwe-oil lubrication ye-bearing, ehambelana nokuvulwa kweyunithi ngexesha leenguqu. enokubangela lula ukuba icoil yemoto itshise;ukongeza, ukungaphumeleli akukwazi ukukhutshwa ngexesha.
2. I-Semi-enclosed screw compressor
Injini epholileyo yokutshiza, ubushushu obuphantsi bemoto, ubomi obude;icompressor evulekileyo isebenzisa umoya ukupholisa i-motor, ubushushu bokusebenza kwemoto buphezulu, obuchaphazela ubomi bemoto, kwaye indawo yokusebenza yegumbi lekhompyutha imbi;ukusetyenziswa kwe-exhaust ukupholisa i-motor, ubushushu bokusebenza kweemoto buphezulu kakhulu, ubomi bemoto bufutshane.Ngokubanzi, ioli yangaphandle inkulu ngobukhulu, kodwa ukusebenza kakuhle kuphezulu kakhulu;ioli eyakhelwe-ngaphakathi idityaniswe kunye ne-compressor, encinci ngobukhulu, ngoko ke umphumo unzima kakhulu. I-plunger semi-enclosed screw compressor iqhutywa ngegiya ukunyusa isantya, isantya siphezulu (malunga ne-12,000 rpm), ukunxiba kukhulu, kwaye ukuthembeka akukuhle.
Isithathu, vula i-screw compressor
Iingenelo zeeyunithi ezivulekileyo zezi: 1) I-compressor ihlukaniswe kwi-motor, ukwenzela ukuba i-compressor inoluhlu olubanzi lwezicelo;2) Icompressor efanayo ingasetyenziswa kwiifriji ezahlukeneyo.Ukongeza kwi-halogenated hydrocarbon refrigerants, i-ammonia ingasetyenziselwa njengefriji ngokuguqula izinto zezinye iindawo;3) Ngokweefriji ezahlukeneyo kunye neemeko zokusebenza, iimoto zamandla ahlukeneyo zinokusetyenziswa.Izinto ezingalunganga eziphambili kwiiyunithi ezivulekileyo zezi: (1) Isitywina se-shaft kulula ukuvuza, okuyiyona nto igcinwa rhoqo ngabasebenzisi;(2) Imoto exhotyiswe ijikeleza ngesantya esiphezulu, ingxolo yokuhamba komoya inkulu, kwaye ingxolo yecompressor ngokwayo inkulu, echaphazela indalo;(3) Kuyimfuneko ukumisela isahluli se-oyile esahlukileyo, i-oyile epholileyo kunye nezinye iinqununu zenkqubo yeoli eyinkimbinkimbi, iyunithi ininzi, ayinzima ukuyisebenzisa kunye nokugcina.
