Nzira yekusarudza hydraulic pressure filters?
Mushandisi anofanira kutanga anzwisisa mamiriro eiyo hydraulic system, uye obva asarudza sefa. Chinangwa chekusarudza ndechekuti: hupenyu hurefu hwesevhisi, nyore kushandisa, uye inogutsa kusefa maitiro.
Kupesvedzera zvinhu zvehupenyu hwesefa Sefa chinhu chakaisirwa mukati meiyo hydraulic sefa inonzi iyo sefa element, uye chinhu chayo chikuru ndicho chidzitiro chesefa. Iyo sefa inonyanya kuruka mesh, bepa sefa, girazi faibha sefa, kemikari fiber sefa uye simbi fiber sefa inonzwa. Iyo sefa midhiya inoumbwa newaya uye akasiyana mafiber haana kusimba mukugadzirwa, kunyangwe iyo nzira yekugadzira yezvinhu izvi inokwidziridzwa (senge: lining, impregnating resin), asi kuchine zvisingakwanisi mumamiriro ekushanda. Zvinhu zvikuru zvinokanganisa hupenyu hwesefa zvinotsanangurwa sezvizvi.
1. Kudonhedza kudonhedza pamigumo miviri yefiritaKana mafuta achipfuura nepakati pesefa, imwe kudonhedza kudonhedzwa kuchagadzirwa pamagumo ese, uye kukosha chaiko kwekudonha kwekumanikidza kunoenderana nechimiro uye kuyerera kwenzvimbo yefirita. Kana iyo sefa inogamuchira kusvibiswa mumafuta, tsvina iyi inoramba iri pamusoro kana mukati mesefa element, ichidzivirira kana kuvharira zvimwe kuburikidza nemakomba kana machannel, kuitira kuti inobudirira kuyerera nzvimbo ideredze, kuitira kuti kudonha kudonha kuburikidza nesefa element kuwedzere. Sezvo tsvina yakavharwa nesefa chinhu ichiramba ichiwedzera, kudzvanywa kunodonha pamberi uye mushure mesefa element inowedzerawo. Aya ma truncated particles anosvina nemaburi epakati uye anopindazve muhurongwa; Kudonhedza kudonhedza kuchawedzerawo saizi yegomba rekutanga, kushandura mashandiro echinhu chesefa uye kuderedza kushanda zvakanaka. Kana kudonhedzwa kwekumanikidzwa kwakakura, kudarika simba rekugadzirisa kwesefa, chinhu chesefa chichave chakapfava uye chakaputsika, kuitira kuti basa resefa rirasikirwe. Kuti iite kuti iyo sefa chinhu ive nesimba rakakwana mukati meiyo yekushanda dzvinyiriro yehurongwa, iyo shoma yekumanikidza iyo inogona kukonzera iyo sefa chinhu kuti igadzikane kazhinji inogadzwa se 1.5 nguva yekumanikidza kushanda kweiyo system. Izvi ndezvechokwadi, apo mafuta anofanira kumanikidzwa kuburikidza nesefa layer pasina bypass valve. Iri dhizaini rinowanzo kuoneka pane yakakwirira-kudzvanywa pombi mafirita, uye kusimba kweiyo sefa chinhu kunofanirwa kusimbiswa mukati memukati skeleton uye lining network (seeiso 2941, iso 16889, iso 3968).
2. Kuenderana kwesefa element uye mafutaIyo sefa ine zvese simbi sefa zvinhu uye zvisiri-metal sefa zvinhu, izvo ndizvo zvakawanda, uye vese vane dambudziko rekuti vanogona kuenderana nemafuta ari muhurongwa. Izvi zvinosanganisira kuenderana kwekuchinja kwemakemikari nekuchinja kwemafuta ekupisa. Kunyanya mumamiriro ekupisa kwepamusoro haagoni kukanganiswa kunonyanya kukosha. Naizvozvo, akasiyana mafirita zvinhu zvinofanirwa kuyedzwa kuenderana kwemafuta pakupisa kwakanyanya (ona ISO 2943).
3.Kukanganisa kwekushanda kwekushisa kwepasiSititi inoshanda pakudziya kwakadzika inewo kukanganisa kwakashata pane sefa. Nekuti pakudziya kwakadzika, zvimwe zvisiri zvesimbi musefa element zvichawedzera kutetereka; Uye pakupisa kwakadzika, kuwedzera kwemafuta viscosity kuchaita kuti kudonha kwekumanikidzwa kusimuke, izvo zviri nyore kukonzeresa kuputika mune zvepakati zvinhu. Kuti uedze mamiriro ekushanda kwesefa pane tembiricha yakaderera, iyo "inotonhora yekutanga" bvunzo yehurongwa inofanirwa kuitwa padanho rekupedzisira tembiricha yehurongwa. MIL-F-8815 ine yakakosha bvunzo maitiro. China Aviation Standard HB 6779-93 zvakare ine zvigadziro.
4. Periodic kuyerera kwemafutaKuyerera kwemafuta muhurongwa kunowanzo kusagadzikana. Kana chiyero chekuyerera chichichinja, chinokonzeresa kukotama deformation yechinhu chesefa. Munyaya yekuyerera kweperiodic, nekuda kwekudzokororwa kudzokororwa kwesefa yepakati zvinhu, zvinokonzeresa kuneta kukuvadzwa kwezvinhu uye kugadzira kuneta kutsemuka. Naizvozvo, iyo sefa mudhizaini kuti ive nechokwadi chekuti iyo sefa chinhu chave chakaringana kuneta kuramba, mukusarudza kwesefa zvinhu zvinofanirwa kuongororwa (ona ISO 3724).
