Pombi yekudzorera mafuta yakavharwa.Kuiswa kwepombi yekudzoka kwemafuta (chinhambwe kubva pasi pechikamu chekuparadzaniswa kwemafuta) hachizadzise zvinodiwa uye kumanikidza kwemhepo kwakadzikira zvakanyanya kana unit iri kushanda.
Iyo yekuparadzanisa mukati medhiramu yekuparadzanisa yakakuvadzwa uye iyo unit ine mafuta ekudonha
Mafuta asina kunaka, furo rakawanda
8. Kuora kwemafuta kana kushandiswa kwenguva refu.9. Mafuta ari muspinner yekunze, kana O-ring ye core chubhu isina kuvharwa, inodonha mafuta.10. Kana chikwata chacho chine mafuta ekudzoka cheki chekivhavha, iyo nzira imwe chete ichaita kuti chikwata chimire Mafuta anoyerera achidzokera kune separator yemafuta, uye inopera mafuta kana ichitangazve.11. Iyo mafuta separator core yakakuvadzwa uye inoputika.
Zvikonzero zvehuwandu hwemafuta mumhepo yakamanikidzwa ye screw air compressors
Oiri uye gasi separator mhando
Oiri kudzorera pombi kana oiri kudzoka cheki vharuvhu yakavharwa
Pressure maintenance valve kuvhura pressure yakadzikira
Zvina: kushandiswa kwekumanikidza kwakanyanya kuderera
shanu: kunaka kwemafuta foam
Iyo yakajairwa dhizaini yekuchengetedza valve yakaiswa pane yakakura kupfuura kana yakaenzana ne0.40Mpa kuburitsa gasi,
Zvakanakisisa kushandisa yepakutanga (yakavakwa-mukati) mafuta uye gasi separator musimboti.Kuti nzvimbo yepombi yekudzorera oiri inodzikiswa kana kwete zvinoenderana nepombi yekudzosa mafuta uye sefa sikirini kana mafuta ekudzoka cheki vharafu.
Air compressor pressure maintenance valve flow rate yakawandisa inogonawo kuburitsa mafuta akawandisa mumhepo yakadzvanywa (kutsemuka kudzvanya kwakadzikira), iyi mamiriro anowanzoitika.
Sei mafuta ekuzora achifanira kutsiviwa nguva nenguva?
Mushure mokunge mafuta ekuzora ashandiswa kune imwe nguva yenguva, inofanira kuchinjwa nguva dzose nekuda kwezvinhu zvinotevera zvinokanganisa kunaka kwemafuta: 1. Metal shavings yakabviswa pamusoro pekuputika nekuda kwekupfeka;2. Guruva nezvimwe zvimedu zvakaoma zvinounzwa nemhepo: 3. Jecha rokuumba risina kunyatsobviswa pakukanda;4. Pendi yependi pane chikamu chemuchina inobviswa;
5. Mafuta ekuzora anogadzira unyoro panguva yekutonhora uye mafuta anowedzera: 6. Kupisa uye mamwe maitiro emafuta ekuzora mumhepo inotenderera zvishoma nezvishoma kuderedza kushanda kwemafuta.
Izvo zvataurwa pamusoro apa zviri nyore kugadzira abrasive paste analogues mumafuta ekuzora, kusvibisa mafuta ekuzora, uye nekumhanyisa kubvongodzwa kweiyo friction pamusoro pemuchina nechisimba.Naizvozvo, kana mafuta ekuzora emuchina zvishoma nezvishoma achidzikira kune anotevera zviratidzo panguva yekushandiswa, anofanira kutsiviwa nemafuta matsva: kana pasina michina yekuongorora uye isingagone kuongororwa, shandura iyo nemafuta matsva maawa maviri kusvika mazana matatu ega ega.Uye nyatsochenesa michina yekugovera mafuta uye imwe neimwe yekuzora poindi.
Ndezvipi zvinhu zvichakanganisa kutama chaiko kweiyo screw compressor
Iyo theoretical displacement ye screw compressor zvinoenderana neiyo inter-zino vhoriyamu, nhamba yemeno uye kumhanya.Iro inter-tooth volume inotarirwa nehukuru hwejometri ye rotor.Kune ma compressor, zvikonzero zvinogoneka zvekuti kutama chaiko kuve kushoma pane iyo theoretical kutamiswa ndeiyi: 1) Leakage.Iko hakuna kushamwaridzana pakati pe rotor uye pakati pe rotor uye casing panguva yekushanda, uye imwe gap inochengetedzwa, saka kubuda kwegesi kuchaitika.Kana gasi rinowedzera kudzvinyirirwa richidonhera papombi yekusveta uye mugodhi unoyamwa nepaburi, vhoriyamu yekuburitsa inodzikiswa.Kuti uderedze kudonha, mazino ekuvhara anogadzirwa pamusoro pezino rerotor inotyairwa, kuvhara magirovha anovhurwa pamudzi wezino rekutyaira rotor, uye mazino ane mhete-akaumbwa kana mitsetse-akaiswa chisimbiso anogadziriswa pachiso chekupedzisira.Kana iyi mitsetse yekuisa chisimbiso yakapfekwa, kudonha kuchawedzera uye vhoriyamu yekuburitsa ichaderera: 2) Inhalation state.Iyo screw compressor ndeye volumetric compressor, uye vhoriyamu yekudhonza inoramba isina kuchinjika.Kana tembiricha yekusveta ichikwira, kana pombi yekusveta kuramba yakakurisa kuti ideredze suction pressure, densi yegasi inodzikira, uye kunaka kwegasi kunodzikira saizvozvo.Displacement:
