Motokari yemagetsi air conditioning compressor (inozonzi electric compressor) sechinhu chakakosha chinoshanda chemota nyowani dzesimba, tarisiro yekushandisa yakakura. Inogona kuve nechokwadi chekuvimbika kwebhatiri remagetsi uye kuvaka yakanaka mamiriro ekunze kune kabhini yevatyairi, asi zvakare inoburitsa kunyunyuta kwekudengenyeka uye ruzha. Nekuti hapana injini ruzha masking, electric compressorruzha rwava imwe yemanyuko makuru eruzha rwemotokari dzemagetsi, uye ruzha rwayo rwemotokari rune mamwe epamusoro-frequency zvikamu, zvichiita kuti dambudziko remhando yekurira rive rakatanhamara. Ruzha rwemhando indekisi yakakosha yekuti vanhu vaongorore uye vatenge mota. Naizvozvo, zvakakosha zvikuru kudzidza mhando dzeruzha uye hunhu hwemhando yemagetsi compressor kuburikidza nekuongorora dzidziso uye nzira dzekuyedza.
Noise mhando uye chizvarwa michina
Ruzha rwekushanda kwemagetsi compressor rinonyanya kusanganisira ruzha rwemagetsi, ruzha rwepneumatic uye ruzha rwemagetsi. Ruzha rwemakanika rinonyanya kusanganisira ruzha rwekukwenya, ruzha rwekukanganisa uye ruzha rwechimiro. Ruzha rweaerodynamic runonyanya kusanganisira exhaust jet noise, exhaust pulsation, suction turbulence ruzha uye suction pulsation. Iyo mechanic yekugadzira ruzha ndeyekutevera:
(1) ruzha rwekukweshana. Zvinhu zviviri zvinosangana zvekufamba kwehama, friction force inoshandiswa munzvimbo yekubata, inosimudzira chinhu kuzunguzika uye inoburitsa ruzha. Iko kufamba kwehukama pakati pe compression maneuver uye static vortex disk inokonzeresa ruzha.
(2) Ruzha rwakashata. Impact noise irwo ruzha rwunogadzirwa nekukanganisa kwezvinhu zvine zvinhu, izvo zvinoratidzwa nepfupi mwaranzi maitiro, asi yakakwirira ruzha mwero. Ruzha rwunogadzirwa neplate yevharuvhu inorova ndiro yevhavha kana compressor ichibuda ndeyeruzha rwekukanganisa.
(3) Ruzha rwemaitiro. Ruzha rwunogadzirwa nekuzunguza kwekunakidzwa uye kutapurirana kwezvivakwa zvakasimba kunonzi ruzha rwechimiro. The eccentric kutenderera kwecompressorrotor uye rotor dhisiki inoburitsa nguva nenguva kunakidzwa kugoko, uye ruzha rwunoburitswa nekuzunguza kwegoko ruzha rwechimiro.
(4) kupera simba. Exhaust ruzha runogona kukamurwa kuita exhaust jet noise uye exhaust pulsation ruzha. Ruzha rwunogadzirwa nekupisa kwepamusoro uye kuburitsa gasi kubva mugomba nekumhanya kukuru ndekwekupedza ruzha rwejeti. Ruzha rwunokonzereswa nekudzikira kwegasi kudzvinyirirwa kwemhepo ndeye exhaust gas pulsation ruzha.
(5) ruzha runokurudzira. Ruzha rwekusveta runogona kukamurwa kuita ruzha rwekusveta turbulence uye ruzha rwekupuruzira. Iyo yemhepo column resonance ruzha inogadzirwa nekusagadzikana kuyerera kwemhepo inoyerera mumugero wekutora ndewekusveta turbulence ruzha. Iyo yekumanikidza kushanduka ruzha inogadzirwa ne periodic suction ye compressor ndeyekukweva pulsation ruzha.
(6) Electromagnetic ruzha. Iko kudyidzana kwemagineti mumhepo gap kunogadzira radial simba rinoshanduka nenguva nenzvimbo, rinoita pane yakagadziriswa uye rotor musimboti, rinokonzeresa deformation yepakati pepakati, uye nekudaro inoburitsa ruzha rwemagetsi kuburikidza nekudengenyeka uye ruzha. Ruzha runoshanda rwecompressor drive mota ndeye electromagnetic ruzha.
NVH bvunzo zvinodiwa uye bvunzo mapoinzi
Iyo compressor yakaiswa paA rigid bracket, uye iyo ruzha bvunzo nharaunda inodiwa kuti ive semi-anechoic kamuri, uye ruzha rwekumashure rwuri pasi pe20 dB (A). Maikorofoni akarongwa kumberi (kurutivi rwekusveta), kumashure (kubuda kwedivi), kumusoro, uye kuruboshwe rwecompressor. Nharaunda pakati penzvimbo ina 1 m kubva geometric centrecompressorpamusoro, sezvinoratidzwa mumufananidzo unotevera.
Mhedziso
(1) Ruzha rwekushanda kweyemagetsi compressor inoumbwa neruzha rwemagetsi, ruzha rwepneumatic uye ruzha rwemagetsi, uye ruzha rwemagetsi rune ruzivo rwakanyanya pamhando yeruzha, uye optimization yemagetsi emagetsi ruzha inzira inoshanda yekuvandudza ruzha. kunaka kwemagetsi compressor.
(2) Pane misiyano iripachena muchinangwa cheparameter kukosha kwemhando yekurira pasi penzvimbo dzakasiyana dzemunda uye akasiyana mamiriro ekumhanya, uye ruzha rwemhando yekumashure ndiyo yakanyanya kunaka. Kudzikisa kumhanya kwecompressor yekushanda pasi pechikonzero chekugutsa kuita kwefiriji uye nekusarudza kutarisisa compressor yakananga kukamuri yevatyairi paunenge uchiita marongero emotokari zvinobatsira mukuvandudza ruzivo rwekutyaira kwevanhu.
(3) Iyo frequency bhendi kugovera kwehunhu ruzha rweiyo compressor yemagetsi uye kukosha kwayo kwepamusoro kunongoenderana nenzvimbo yemunda, uye haina chekuita nekumhanya. Iwo ruzha rwepamusoro peimwe neimwe yemunda ruzha runonyanya kugoverwa pakati uye yakakwirira frequency bhendi, uye hapana masking yeinjini ruzha, izvo zviri nyore kucherechedzwa uye kunyunyuta nevatengi. Zvinoenderana nehunhu hweacoustic insulation zvinhu, kutora acoustic insulation matanho munzira yayo yekutapurirana (sekushandisa acoustic insulation chivharo chekuputira compressor) inogona kunyatso kudzikisa kukanganiswa kwemagetsi compressor ruzha pamotokari.
