1. Chii chinonzi "chaiyo simba" remhepo compressor?
Simba chairo, kana kuti "unit input specific power" zvinoreva chiyero chesimba rekupinza remhepo compressor unit kune chaiyo volumetric kuyerera kwemhepo compressor pasi pemamiriro ekushanda akatsanangurwa.
Ndiro simba rinodyiwa necompressor per unit volume flow.Icho chiratidzo chakakosha chekuongorora kushanda kwesimba re compressor.(Dzvinyirira gasi rimwe chete, pasi pesimba rakafanana rekupedza simba).
ps.Imwe data yapfuura yainzi "volume chaiyo simba"
Simba chairo = unit yekupinza simba/volume flow
Chikamu: kW/ (m3/min)
Volumetric flow rate - iyo volumetric kuyerera kwegasi yakamanikidzwa uye inoburitswa nemhepo compressor unit pane yakajairwa exhaust chinzvimbo.Kuyerera uku kunofanirwa kuchinjirwa kune tembiricha yakazara, kudzvanywa kwakazara uye chikamu (senge humidity) mamiriro pane yakajairwa yekusveta chinzvimbo.Chikamu: m3/min.
Simba rekupinza reyuniti - iro rose rekuisa simba reiyo air compressor unit pasi peyakayerwa magetsi emagetsi mamiriro (senge nhamba yechikamu, voltage, frequency), unit: kW.
"GB19153-2009 Energy Efficiency Limits uye Energy Efficiency Levels yeVolumetric Air Compressors" ine mitemo yakadzama pamusoro peizvi.
2. Chii chinonzi air compressor simba rekuita magiredhi uye mavara ekugadzirisa simba?
Igiredhi rekushanda kwesimba ndiwo mutemo weiyo yakanaka yekutamisa mweya compressors mu "GB19153-2009 Energy Efficiency Limits uye Energy Efficiency Grades of Positive Displacement Air Compressors".Uye zvakare, zvigadziriso zvinogadzirwa zvesimba rekushandisa simba muganho, inotarirwa simba rekushandisa simba, kukosha kwekuchengetedza simba rekuongorora, nzira dzekuyedza uye mitemo yekuongorora.
Iyi chiyero inoshanda kune yakananga-yakabatana inotakurika inodzosera piston air compressors, miniature inodzorera piston air compressors, yakazara-isina mafuta inodzosera piston air compressors, general fixed reciprocating piston air compressors, general oil-ijection screw air compressors, general Shandisa mafuta-jekiseni imwechete- screw air compressors uye kazhinji shandisa mafuta-injected sliding vane air compressors.Inovhara iwo makuru ezvimiro emhando yeakanaka displacement air compressors.
Kune matatu mazinga ekuita simba kweakanaka displacement air compressors:
Level 3 simba rekushandisa: simba rekuita muganho kukosha, kureva kukosha kwesimba rinofanirwa kuwanikwa, kazhinji zvigadzirwa zvinogoneka.
Level 2 simba rekushandisa: Zvigadzirwa zvinosvika paNhamba 2 simba rekushandisa kana pamusoro, kusanganisira Level 1 simba rekushandisa, zvigadzirwa zvinochengetedza simba.
Level 1 simba rekushandisa: yakanyanya kunaka simba, yakaderera mashandisiro esimba, uye yakanyanya kuchengetedza simba chigadzirwa.
Energy efficient label:
Chiratidzo chekushanda kwesimba chinoratidza "simba rekushanda kwesimba" remhepo compressor yakatsanangurwa munyaya yapfuura.
Kutanga kubva munaKurume 1, 2010, kugadzirwa, kutengeswa uye kuendesa kunze kwenyika kwema compressor emhepo akadzikama munyika yeChina kunofanirwa kuve nemagetsi ekushandisa simba.Zvigadzirwa zvine hukama zvine mwero wekushandisa simba wakaderera pane level 3 hazvibvumidzwe kugadzirwa, kutengeswa kana kutengwa kunze kwenyika muChina.Yese yakanaka displacement air compressors inotengeswa pamusika inofanirwa kuve ine simba rekushandisa label rakaiswa munzvimbo inoonekera.Kana zvisina kudaro, kutengesa hakubvumirwi.
3. Ndezvipi "matanho", "zvikamu" uye "makoroni" emhepo compressors?
Mune yakanaka displacement compressor, nguva imwe neimwe gasi painomanikidzwa mukamuri yekushanda, gasi rinopinda muinotonhorera yekutonhodza, iyo inonzi "nhanho" (chikamu chimwe chete).
Ikozvino iyo ichangoburwa-yekuchengetedza simba modhi ye screw air compressor ndeye "two-stage compression", iyo inoreva makamuri maviri ekushanda, maitiro maviri ekumanikidza, uye mudziyo wekutonhodza pakati pemaitiro maviri ekumanikidza.
ps.Iwo maviri compression maitiro anofanirwa kubatanidzwa munhevedzano.Kubva kudivi rekuyerera kwemhepo, maitiro ekumanikidza anotevedzana.Kana misoro miviri yakabatanidzwa mukufanana, haikwanise kunzi kudzvanywa kwematanho maviri zvachose.Kana iri iyo yakatevedzana yekubatanidza yakabatanidzwa kana yakaparadzana, ndiko kuti, ingave yakaiswa mune imwe casing kana maviri casings, haina kukanganisa ayo maviri-nhanho compression zvivakwa.
Mune yekumhanyisa-mhando (simba-mhando) compressor, inowanzo kudzvanywa neinopetera kaviri kana kupfuura isati yapinda muinotonhorera yekutonhodza.Iwo akati wandei ekumanikidza "matanho" ekutonhora kwega kwega anonzi pamwe chete "segment" .MuJapan, iyo "nhanho" yeakanaka displacement compressor inonzi "chikamu".Kupesvedzerwa neizvi, mamwe matunhu uye magwaro ega ega muChina anodanawo "danho" "chikamu".
Single-stage compressor-gasi inomanikidzwa chete kuburikidza nekamuri imwe yekushanda kana impeller:
Maviri-nhanho compressor-iyo gasi inomanikidzwa kuburikidza nemakamuri maviri ekushanda kana impellers mukuteerana:
Multi-stage compressor-iyo gasi inomanikidzwa kuburikidza nemakamuri akawanda ekushanda kana impellers munhevedzano, uye nhamba inoenderana yekupfuura ndiyo akati wandei-nhanho compressor.
"Column" inonyatso reva boka repiston rinoenderana nepakati mutsara wekubatanidza tsvimbo yemuchina wepiston unodzokorora.Inogona kupatsanurwa kuita imwe-mutsara uye akawanda-mutsara compressors zvichienderana nehuwandu hwemitsara.Ikozvino, kunze kwema micro compressors, mamwe ese akawanda-mutsetse wekumanikidza muchina.
5. Chii chinonzi dova?
Dew point, inova tembiricha yedova.Itembiricha apo mweya wakanyorova unotonhora kusvika pakuzara pasina kushandura chikamu chekumanikidza kwemhute yemvura.Chikwata: C kana kutya
Tembiricha panotonhodzwa mhepo ine mwando pasi pekumanikidzwa kwakaenzana kuitira kuti mhute yemvura isina unsaturated pakutanga iri mumhepo ive mhute yemvura yakazara.Nemamwe mashoko, apo tembiricha yemhepo inodonha kusvika kune imwe tembiricha, mhute yepakutanga isina kuzara yemvura iri mumhepo inozara.Kana pasvikirwa (kureva kuti, mhute yemvura inotanga kunyungudika nekubuda), tembiricha iyi ndiyo tembiricha yedova regasi.
ps.Saturated air - Kana pasisina mhute yemvura inogona kubatwa mumhepo, mweya wakazara, uye chero kudzvanywa kana kutonhora kunotungamira kunaya kwemvura yakapfupikiswa.
Atmospheric dew point (atmospheric dew point) zvinoreva tembiricha apo gasi rinotonhodzwa kusvika pakusvika apo mhute yemvura isina kuzara iri mairi inova mhute yemvura yakazara uye inonaya pasi pesimba remuchadenga.
Pressure dew point inoreva kuti kana gasi rine imwe pressure ikatonhodzwa kusvika kune imwe tembiricha, mupfunga wemvura usina unsaturated uri mariri unoshanduka kuita mhute yemvura yakazara uye ichinaya.Iyi tembiricha ndiyo inomanikidza dova regesi.
Mukutaura kwe layman: Mhepo ine hunyoro inogona kungobata humwe hunyoro hwehunyoro (mumamiriro egasi).Kana iyo vhoriyamu yakaderedzwa nekumanikidza kana kutonhora (magasi anodzvanywa, mvura haisi), hapana mweya wakakwana wekubata hunyoro hwese, saka mvura yakawandisa inoputika se condensation.
Mvura yakapfupikiswa mumhepo-yemvura yekuparadzanisa mumhepo compressor inoratidza izvi.Mhepo inosiya mutonhodza wepashure nokudaro ichiri yakazara zvizere.Kana tembiricha yemhepo yakamanikidzwa ichidonha munzira ipi neipi, mvura yekutsikisa icharamba ichigadzirwa, ndosaka paine mvura mupombi yemhepo yakamanikidzwa kumucheto kumashure.
Kuwedzeredza kunzwisisa: Iyo gasi yekuomesa musimboti wefiriji yekuomesera - iyo yakaomeswa mufiriji inoshandiswa kuseri kwekupedzisira kwemhepo compressor kutonhodza mweya wakatsikirirwa kusvika kune tembiricha yakaderera pane ambient tembiricha uye yakakwirira kupfuura nzvimbo yechando (ndiko kuti, dova. point tembiricha yefiriji dryer).Sezvinobvira, bvumira hunyoro huri mumhepo yakamanikidzwa kuti inyunde mumvura ine mvura uye idonhe.Mushure meizvozvo, mweya wakamanikidzwa unoramba uchiendeswa kumagumo egasi uye zvishoma nezvishoma unodzokera kune ambient tembiricha.Chero bedzi tembiricha isingachadziki pane tembiricha yakaderera yakambosvikwa neinotonhora yakaoma, hapana mvura yemvura inobuda kubva mumhepo yakamanikidzwa, iyo inozadzisa chinangwa chekuomesa mweya wakamanikidzwa.
*Muindasitiri yemhepo compressor, dova rinoratidza kuoma kwegasi.Kudzika kwe tembiricha yedova, ndiko kuoma kwayo
6. Noise uye Sound Assessment
Ruzha kubva kune chero muchina ruzha runogumbura, uye ma compressor emhepo haana mutsauko.
Kune ruzha rwemaindasitiri senge yedu compressor yemhepo, tiri kutaura nezve "sound power level", uye chiyero chekuyera kusarudzwa ndeye "A" level ruzha nhanho_-dB (A) (decibel).
Iyo yenyika chiyero "GB/T4980-2003 Kutemerwa kweruzha rweakanaka displacement compressors" inotsanangura izvi.
Mazano: Mune maitiro ekuita anopihwa nemugadziri, zvinofungidzirwa kuti iyo air compressor ruzha mwero i70+3dB(A), zvinoreva kuti ruzha rwuri mukati meiyo 67.73dB (A).Zvichida iwe unofunga kuti chiyero ichi hachina kunyanya kukura.Chokwadi: 73dB(A) yakasimba zvakapetwa kaviri se70dB(A), uye 67dB(A) ine hafu yakasimba se70dB(A).Saka, uchiri kufunga here kuti iyi nhanho idiki?
