Kudzvanya gasi inzira yekushandisa simba rekunze kuti gasi riwedzere simba, uye compressor ndiyo inogadzira gasi rakamanikidzwa. Saka, mashandiro ekutanga emhepo ye screw air compressor air end haaparadzaniswi nezvinhu izvi zvina: kumanikidzwa, kuyerera, simba uye simba rakati.
Kushanda kwekutanga kwe screw air compressor air end - kumanikidzwa
Kuwana simba rekumanikidza remhepo yakamanikidzwa ndiko kushanda kwakanyanya kwecompressor yemhepo, uye screw air compressor haina musiyano. Screw air compressor air end inowedzera kumanikidzwa kwemhepo nekushandisa simba rekunze. Kana kumanikidzwa kwacho kwakakwira, simba rakawanda rinoshandiswa, uye zvinodiwa zvemhepo zvinokwira. Kazhinji tinokamura macompressor emhepo muzvikamu zvina zvichienderana nekumanikidzwa kwemhepo:
Kudzvanywa kwakaderera: 0.2~1.0MPa Kudzvanywa kwepakati: 1.0~10MPa Kudzvanywa kwakanyanya: 10~100MPa Kudzvanywa kwakanyanya: pamusoro pe100MPa
Compressor yemhepo ine sikuruu inowanzova nekumanikidzwa kunobuda kwe0.2 ~ 4.0MPa, zvinoreva kuti mashandiro ayo, kugona kwayo uye kushaya simba zviri nani pane izvi. Izvi zvinotsanangurwa nechimiro uye mashandiro emhepo yecompressor, uye ndiyowo chikamu chekumanikidzwa chinodiwa zvakanyanya pamusika.
Kumanikidzwa kwemhepo kunopihwa necompressor yemhepo kunonyanya kuyerwa nechiyero chekumanikidzwa, chinova chiyero chekumanikidzwa kwekubuda Pd nechisimba chekusvuta Ps. Chiyero chakakwira, kumanikidzwa kwekubuda kwakakwira. ε=Pd/Ps Formula (6)
Kune injini huru ye screw air compressor, kune chiyero chekumanikidzwa kwemukati uye chiyero chekumanikidzwa kwekunze.
Chiyero chekumanikidzwa kwemukati: chiyero chekumanikidzwa muhuwandu hwepakati pemazino einjini huru nekumanikidzwa kwekusvuta, izvo zvinotsanangurwa nenzvimbo uye chimiro chenzvimbo dzekusvuta nekuburitsa mweya;
Chiyero chekumanikidzwa kwekunze: chiyero chekumanikidzwa kuri mupombi yekuburitsa utsi nekumanikidzwa kwekusvuta. Kumanikidzwa kwekusvuta nekubuda kweutsi kunodiwa pakushanda kana kuyerera kwemaitiro.
Kana chiyero chekumanikidzwa kwemukati chikapfuura chiyero chekumanikidzwa kwekunze, injini huru inoshandisa simba rakawanda; kana chiyero chekumanikidzwa kwemukati = chiyero chekumanikidzwa kwekunze, injini huru inenge iri mumamiriro akanaka kwazvo.
Kana injini huru ye screw air compressor yakafanana, kana injini huru, tembiricha yemhepo, kumanikidzwa kwekusveta, kumhanya kweinjini huru nezvimwe zvinhu zvakafanana, kumanikidzwa kwekubuda kwakakwira, simba rinoshandiswa zvakanyanya.
Kushanda kwekutanga kwe screw air compressor air end - flow yemhepo
Kuyerera kunowanzo umbwa nekuyerera kwehuwandu uye kuyerera kwehuwandu. Muindasitiri yehurongwa hwekumanikidza mweya uye zviyero, tinowanzo shandisa kuyerera kwehuwandu senzira yekuyera kuyerera, iyo inonziwo huwandu hwekubuda kwemhepo kana kuyerera kwezita rezita munyika yangu: pasi pekumanikidzwa kwemhepo kunodiwa, huwandu hwegasi rinoburitswa necompressor yemhepo panguva imwe neimwe rinoshandurwa kuita mamiriro ekupinda, kureva kuti, kukosha kwehuwandu hwekumanikidzwa kwekusveta papombi yekutanga yekupinda uye tembiricha yekusveta nehunyoro. Chiyuniti i m3/min. Kuyerera kwehuwandu kwakakamurwa kuita kuyerera kwehuwandu chaihwo uye kuyerera kwehuwandu hwakajairika.
Kazhinji, masampuli, sarudzo, uye mazita emuchina anoshandisa kuyerera kwehuwandu hwakajairika. Nekuda kweindasitiri, dunhu uye mashandisirwo, kuyerera kwehuwandu hwakajairika mumusika wemhepo yakamanikidzwa kune tsananguro mbiri zvichienderana nemusiyano uripo mumamiriro akajairwa (tembiricha, kumanikidzwa uye zvikamu):
Mamiriro akajairwa ndeekuti kumanikidzwa P=101.325KPa; tembiricha yakajairwa T=0℃; hunyoro hwepakati i0%. Inowanzoonekwa mumagwaro egasi remaindasitiri, indasitiri yemakemikari kana magwaro ekubhidha, anonzi "standard square", kazhinji kacho ane chiratidzo chekuti "VN" uye unit yeNm3/min.
Mamiriro akajairwa ndeekuti kumanikidzwa P = 101.325KPa; tembiricha yakajairwa T = 20℃; hunyoro hwepakati i0%. Inowanzo shandiswa muzviyero zveindasitiri yemhepo yakamanikidzwa uye inonzi "mamiriro ekushanda akajairwa". Chiratidzo chinowanzova "V" uye unit yacho i m3/min.
Kazhinji, mwero wehuwandu hwemhepo inoshandiswa muindasitiri yedu yecompressor yemhepo ndiyo yekupedzisira. Kuchinja kwehuwandu hwehuwandu hwemhepo pasi pemamiriro maviri aya kunogona kuverengerwa nefomura:
V(m3/min)=1.0732VN(Nm3/min) Fomula (7)
Kana injini huru ye screw air compressor ikaita seyiyi, pasi pemamwe mamiriro akafanana, daro repakati pe rotor rakakura, vhoriyamu yekufamba kwayo yakakura; kumhanya kweinjini huru kwakakwira, vhoriyamu yekufamba kwayo yakakura.
Mwero wekuyerera kweVvolume = qv vhoriyamu yekumanikidzwa kweinjini huru × n kumhanya kwemusoro Fomura (8)
qv=CΨqv0Z1n=CΨCn1nλD3 Fomura (9)
Apo Z1——nhamba yemazino emukono werotor; n——kumhanya kwemukono werotor; λ——rotor aspect ratio; D——dhayamita yekunze yemukono werotor.
Saka, nekuda kwekuchengetedza mari, tinowanzo deredza mhando dzeinjini huru uye tinogona kugadzirisa huwandu hwemhepo inobuda mumhepo nekuona kumhanya kweinjini huru kuti ienderane nezvinodiwa pamusika.
Zvisinei, kumhanya kweinjini huru ye screw compressor hakugone kuva kwakakwirira zvikuru, kazhinji pakati pe 800 ne 10,000 rpm. Nokudaro, mugadziri weinjini huru ye screw anogadzira mainjini makuru ane huwandu hwakasiyana hwekuyerera kwehuwandu kuti asvike pazvinodiwa ne screw compressor.
Zvichienderana nehukuru hwemhepo yakamanikidzwa, macompressor emhepo anogona kukamurwa kuita:
Kompresa diki<1m3>10～<100 m3min; large compressor ≥100 min
Chinosimudzira mhepo chikuru chakakodzera muchina mumwe chete une 1 100 m3/min, inova ndiyo yakavimbika uye isingadhuri, uye ndiyo modhi huru mumusika wecompressor yemhepo.
Kumanikidzwa kwakanyanya, simba rinoshandiswa neinjini huru; vhoriyamu yakawanda, simba rinoshandiswa neinjini huru
Kana simba reinjini huru ye screw air compressor rikaderera, simba rayo rinoshandiswa rinoderedza uye mashandiro einjini huru ari nani. Kana injini huru ichifamba nguva dzose, kumanikidzwa kwayo kunowedzera, simba re shaft reinjini huru rinokura, saka simba rayo guru rinokura.
Injini yega yega ye screw air compressor ine simba rayo rakakodzera, iro rine chekuita nekumhanya kweinjini huru. Kana kumhanya kweinjini huru kwakaderera, kubuda kwemvura kunowedzera, huwandu hwegasi hunoderera, uye simba rayo rinokwira; kana kumhanya kweinjini huru kwakakwira zvakanyanya, kukweshana kunowedzera, simba remubato rinowedzera, uye simba rayo rinokwira. Asi panofanira kunge paine kumhanya kwakakodzera kunoita kuti simba rayo rive rakaderera. Ndokusaka zvisiri zvechokwadi kutaura kuti kana injini huru yakakura, ndipo painochengetedza simba zvakanyanya.
Patinogadzira macompressor emhepo ane screw uye macompressor emhepo ane frequency inochinja-chinja, uku tichiona kuti mhando yeinjini huru haishande zvakanaka, tinofanirawo kufunga nezvehupfumi hwayo, kurongeka kwayo uye modularity yayo. Saka, tichashandisa curve yesimba reinjini huru kugadzira nekugadzira macompressor emhepo ane pressure dzakasiyana uye flows.
