Tsanangudzo yakadzama yechimiro chemukati checompressor inodzokorora
Reciprocating compressors anonyanya kuumbwa nemuviri, crankshaft, yekubatanidza tsvimbo, piston boka, mhepo vharafu, shaft chisimbiso, pombi yemafuta, mudziyo wekugadzirisa simba, oiri kutenderera system uye zvimwe zvinhu.
Izvi zvinotevera sumo pfupi kune zvakakosha zvikamu zve compressor.
muviri
Muviri wecompressor inodzoreredza ine zvikamu zviviri: cylinder block uye crankcase, izvo zvinowanzokandwa zvakazara uchishandisa yakakwirira-simba grey cast iron (HT20-40).Ndiwo muviri unotsigira huremu hwecylinder liner, crankshaft yekubatanidza tsvimbo meshini uye zvimwe zvikamu zvese uye inovimbisa iyo chaiyo hukama chinzvimbo pakati pezvikamu.Silinda inotora cylinder liner chimiro uye inoiswa muhumbururo yechigaro chechigaro pane cylinder block kuti ive nyore kugadzirisa kana kutsiva kana silinda liner yapfekwa.
crankshaft
Iyo crankshaft ndechimwe chezvinhu zvikuru zveiyo compressor inodzokorodza uye inotumira simba rese re compressor.Basa rayo guru ndere kushandura kutenderera kutenderera kwemota kuita inodzokorodzana mutsara kufamba kwepiston kuburikidza netambo yekubatanidza.Kana iyo crankshaft ichifamba, inotakura inochinjana mitoro yekumanikidzana, kudzvanya, kugera, kukotama uye torsion.Mamiriro ekushanda ane hutsinye uye anoda simba rakakwana uye kuomarara pamwe nekupfeka kuramba kwejenari guru uye crankpin.Naizvozvo, crankshaft inowanzogadzirwa kubva pa40, 45 kana 50-zvakanaka-yemhando yepamusoro kabhoni simbi.

Tsvimbo yekubatanidza ndiyo chidimbu chekubatanidza pakati pe crankshaft nepiston.Iyo inoshandura kutenderera kutenderera kwe crankshaft kuita kudzoreredza kufamba kwepiston, uye inoendesa simba kune piston kuita basa pagesi.Mutambo wekubatanidza unosanganisira muviri wetsvimbo yekubatanidza, tsvimbo yekubatanidza duku yekupedzisira bushing, iyo yekubatanidza tsvimbo yakakura yekupedzisira inotakura bush uye yekubatanidza tsvimbo yebhaudhi.Chimiro chetsvimbo yekubatanidza inoratidzwa muMufananidzo 7. Muviri wetsvimbo yekubatanidza inotakura kushandura kugadzikana uye kumanikidzika mitoro panguva yekushanda, saka inowanzogadzirwa nepamusoro-soro yepakati kabhoni simbi kana kukanda ne ductile iron (yakadai seQT40-10).Muviri wetsvimbo unonyanya kutora I-shaped cross-section uye gomba refu rinoboorwa nepakati senzira yemafuta..
cross head
Muchinjikwa ndicho chikamu chinobatanidza piston tsvimbo nekubatanidza tsvimbo.Iyo inogadzira kudzoreredza kufamba mukati memuviri wepakati chekutungamira njanji uye inotumira simba rekubatanidza tsvimbo kune chikamu chepiston.Muchinjikwa wacho unonyanya kuumbwa nemuviri wemuchinjika, pini yepini, shangu yemuchinjiko uye mudziyo wekusimbisa.Izvo zvinodikanwa zvekuchinjisa musoro ndezvekureruka, kusapfeka uye kuve nesimba rakakwana.Muviri wemuchinjika wakapetwa kaviri-mativi cylindrical chimiro, iyo inomisikidzwa neshangu dzinotsvedza kuburikidza nerurimi uye mugoro uye yakabatana pamwechete nema screws.Iyo crosshead inotsvedza shangu chivakwa chinotsiviwa, chine alloy inokandwa pamusoro pekudzvanywa-inotakura pamusoro uye mafuta grooves uye nzira dzemafuta.Mapini eCrosshead akakamurwa kuita cylindrical uye tapered pini, akadhirowa neshaft uye radial mafuta maburi.
filler
Kurongedza kunonyanya chikamu chinosimbisa gap pakati pehumburumbira nepiston tsvimbo.Inogona kudzivirira gasi kubva pahumburumbira ichipinda mufuselage.Mamwe macompressor akakamurwa kuita pre-packing mapoka uye post-packing mapoka zvichienderana negasi kana zvinodiwa nemushandisi kune hukasha.Iwo anowanzo shandiswa mune chepfu, chinopisa, chinoputika, chakakosha gasi, isina mafuta uye mamwe macompressor.Iwo mapoka maviri emapoka ekurongedza ari Pane mupanda pakati.
Pre-packing inonyanya kushandiswa kuvhara gasi mucompressor cylinder kubva pakubuda.Iko kurongedza kwemashure kunoshanda sechisimbiso chekubatsira.Mhete yekuisa chisimbiso kazhinji inotora chisimbiso chenzira mbiri.Iko kune inodzivirira gasi inlet yakarongwa mukati memhete yekuisa chisimbiso.Inogonawo kushandiswa pamwe chete nemafuta scraper ring.Iko hakuna nzvimbo yekuzora uye hapana yekutonhodza mudziyo.
Piston boka
Boka repiston ndiro izwi rakajairika repiston tsvimbo, piston, piston mhete uye mhete yekutsigira.Inotyairwa netsvimbo yekubatanidza, boka repiston rinoita kudzoreredza mutsara kufamba muhumburumbira, nokudaro richigadzira vhoriyamu yekushanda inoshanduka pamwe chete necylinder kuti iwane kuyamwa, kudzvanya, kupera uye mamwe maitiro.
Tsvimbo yepiston inobatanidza piston kune musoro, inotumira simba rinoshanda papiston, uye inotyaira piston kuti ifambe.Kubatana pakati pepiston uye piston tsvimbo inowanzotora nzira mbiri: cylindrical shoulder uye cone connection.
Mhete yepiston chikamu chinoshandiswa kuvhara mukaha pakati pecylinder mirror nepiston.Inotambawo basa rekugovera mafuta uye kupisa conduction.Izvo zvakakosha zvinodikanwa zvepiston mhete ndeye yakavimbika chisimbiso uye kupfeka kuramba.Mhete yekutsigira inonyanya kutsigira huremu hwepiston uye piston tsvimbo uye inotungamira piston, asi haina basa rekuvhara.
Kana silinda ichizorwa nemafuta, mhete yepiston inoshandisa mhete yesimbi yakakandwa kana mhete yepurasitiki yePTFE yakazadzwa;kana kudzvinyirirwa kwakakwirira, mhete yemhangura yepiston inoshandiswa;iyo mhete yekutsigira inoshandisa mhete yepurasitiki kana iyo inotakura alloy inokandwa yakananga pamuviri wepiston.Kana silinda ichizorwa pasina mafuta, mhete yepiston yekutsigira inozadzwa ne polytetrafluoroethylene mhete dzepurasitiki.
mhepo vharafu
Ivhavha yemhepo chikamu chakakosha che compressor uye chikamu chakapfeka.Hunhu hwayo uye hunhu hwekushanda hunokanganisa zvakananga huwandu hwekutakura gasi, kurasikirwa kwesimba uye kuvimbika kwekushanda kwecompressor.Ivhavha yemhepo inosanganisira vharafu yekusveta uye vheji yekupedza.Pese pese piston painodzokerana kumusoro nekudzika, mavharuvhu ekukweva uye ekubuditsa anovhura nekuvhara nguva yega yega, nekudaro achidzora compressor nekuibvumira kupedzisa mana ekushanda maitiro ekudhonza, kudzvanya, uye kupera simba.
Anowanzo shandiswa compressor mweya mavharuvhu akakamurwa mesh mavharuvhu uye annular mavharuvhu maererano vharafu ndiro chimiro.
Iyo annular valve inoumbwa nechigaro chevhavha, ndiro yevhavha, chitubu, chigadziro chekusimudza, mabhoti ekubatanidza uye nuts, nezvimwewo. Maonero akaputika anoratidzwa muMufananidzo 17. Ivhavha yevhavha iri nyore kugadzira uye yakavimbika mukushanda.Nhamba yezvindori inogona kuchinjwa kuti ienderane kune akasiyana gasi vhoriyamu zvinodiwa.Izvo zvisingabatsiri zveannular valves ndezvokuti zvindori zvemahwendefa evharuvhu zvakaparadzaniswa kubva kune mumwe nemumwe, zvichiita kuti zvive zvakaoma kuwana matanho anowirirana panguva yekuzarura nekuvhara maitiro, nokudaro kuderedza simba rekuyerera kwegesi uye kuwedzera kuwedzera kurasikirwa kwesimba.Zvinhu zvinofamba zvakadai seplate yevharuvhu zvine huwandu hukuru, uye pane kukakavara pakati peplate yevharuvhu nebhuroka rekutungamira.Mhete dzemhete dzinowanzoshandisa cylindrical (kana conical) zvitubu nezvimwe zvinhu, izvo zvinotarisa kuti hazvisi nyore kuti ndiro yevhavha ivhure uye ivhare munguva yekufamba.,kutsanya.Nekuda kwekusagadzikana kwevhavha plate, kupfeka kwakakomba.
Mahwendefa evharuvhu evharuvhu anobatanidzwa pamwe chete mumarin'i kuti aite mesh shape, uye imwe kana akati wandei mabuffer plates ayo ane chimiro chakafanana nema plates evharuvhu anorongwa pakati peplate yevharuvhu neinosimudza limiter.Mesh mavharuvhu akakodzera kune akasiyana siyana ekushanda mamiriro uye anowanzoshandiswa mune yakaderera uye yepakati kudzvanywa matunhu.Zvisinei, nekuda kwechimiro chakaoma chemesh valve plate uye nhamba huru yezvikamu zvevhavha, kugadzirisa kwakaoma uye mari yakakwirira.Kukuvadza kune chero chikamu cheplate yevharuvhu kuchaita kuti ndiro yevhavha yose iparadzwe.
