Mune hydraulic magetsi masisitimu, radial piston pombi uye axial piston mapombi maviri epakati matekinoroji, achitora akasiyana masisitimu ekushandisa neayo akasiyana dhizaini uye maitiro ekuita. Kunyangwe vese vari vaviri vachiona kushandurwa kwesimba remagetsi kuburikidza nekudzokorodza kufamba kwepiston, pane misiyano yakakura muchimiro chavo chemukati, maitiro ekushanda uye mamiriro anoshanda.
Misiyano yepakati: "radial" uye "parallel" kurongeka kwepiston
1. Hydraulic radial piston pombi: mapistoni akagoverwa radially
Zvimiro zvechimiro: Iwo mapistoni akarongedzerwa muchimiro chenyeredzi padivi peiyo radial nzira yedhiraivha shaft (yakafanana nevhiri spokes), perpendicular kune main shaft.
Kushanda musimboti: Iyo piston iri padyo ne eccentric cam ring (Cam Ring) kuburikidza ne centrifugal simba kana mechanic push. Sezvo rotor inotenderera, piston inodzokorora mugomba reradial kuti ipedze kusveta kwemafuta uye maitiro ekumanikidza kwemafuta.
Zvikamu zvakakosha: eccentric cam ring, rotor cylinder, kugovera shaft.
2. Hydraulic axial piston pombi: pisitoni yakarongedzerwa yakafanana kune huru shaft.
Mamiriro ezvinhu: Iyo piston inofananidzwa nedhiraivha shaft uye yakaenzana yakagoverwa muhumburumbira inotenderera.
Kushanda musimboti: Iyo plunger inowana kudzoreredza kufamba kuburikidza neinorerekera kona yeiyo swashplate kana yakakombama axis. Iyo yakakura iyo swashplate angle, iyo yakareba iyo plunger sitiroko uye inokwidza inobuda kubuda.
Zvikamu zvakakosha: swashplate / bent axis, silinda inotenderera, ndiro yekuparadzira.
Kuenzanisa kwekuona:
Radial pombi: Chimiro chakanyanya "chakasimba", chakakodzera ultra-high pressure, asi vhoriyamu yakakura.
Axial pombi: Chimiro chakanyanya "compact", chakakodzera kumhanya kwepamusoro, kusiyanisa kudzora, uye ine yakakwirira simba density.
Kuenzanisa kwekuita: kumanikidzwa, kushanda zvakanaka, hupenyu uye ruzha
1. Kudzvinyirira simba
Radial piston pombi: Yakagadzirirwa ultra-high pressure (pamusoro pe600-1000 bar), yakadai se hydraulic presses, midziyo yakadzika-gungwa uye mamwe mamiriro ekushanda akanyanyisa.
Axial piston pombi: Iyo mainstream pressure range ndeye 200-450 bar, uye mamwe emhando yepamusoro anogona kusvika 600 bar, akakodzera kumichina yekuvaka, majekiseni ekuumba majekiseni, nezvimwe.
Mhedziso: Kana iyo system yekumanikidza kudiwa ichipfuura 500 bar, iyo radial pombi ndiyo chete sarudzo; kana iri pasi pe400 bar, iyo axial pombi inodhura-inoshanda.
2. Kuyerera kugadzikana uye ruzha
Pombi yeRadial: maplungers mashoma (kazhinji 5-7), kuyerera kwakakura, ruzha rwepamusoro (pamusoro pe80 dB).
Axial pombi: yakawanda plungers (7-9 kana kupfuura), inoyerera inoyerera inobuda, yakaderera ruzha (70-75 dB).
Kukanganisa kwekushandisa: Mapombi eAxial anofarirwa pazviitiko zvinonzwa ruzha (semidziyo yekurapa nematurusi emuchina chaiwo).
3. Kubudirira uye kushanduka kwekutonga
Pombi yeRadial:
High mechanical kunyatsoshanda (92% +), asi yakaoma kushandura kushanduka, cam eccentricity kugadziriswa, kunonoka kupindura.
Inokodzera kugadziriswa kwakagadziriswa kana pasi-speed uye high-pressure mamiriro.
Axial pombi:
Yakakwira volumetric kunyatsoshanda (95%+), inochinjika chinja chinja (nekugadzirisa kona yepureti yekutsvaira), uye nekukurumidza kupindura.
Inokodzera kuchinjika frequency yekumhanya uye masisitimu ekuchengetedza simba (sekuchera uye mhepo inosiyanisa pitch masisitimu).
4. Hupenyu nekuchengetedza
Radial pombi: chimiro chakareruka, kuramba kwakasimba kusvibiswa, kwakakodzera nharaunda dzakaomarara (senge muchina wemigodhi).
Axial pombi: Iyo yekugezesa ndiro uye plunger peya zvine zvakakwirira zvinodiwa pakuchena kwemafuta uye zvinoda kusefa kwakanaka (NAS 1638 Kirasi 6 kana pamusoro).
Kuenzanisa kwezvakajairwa zvekushandisa zviitiko
1. Nzvimbo huru yehondo yemapombi eradial piston
Ultra-yakanyanya kudzvanywa hydraulic system:
Metal kuumba (hydraulic press, forging press)
Midziyo yakadzika-gungwa (ROV hydraulic power)
Indasitiri yemauto (submarine hydraulic system)
Zvakanyanya nharaunda:
Migodhi muchina (kusvibisa kuramba, kukanganisa kuramba)
Kuchera mafuta (high-pressure mud pump)
2. Munda mukuru weaxial piston pombi
Mobile hydraulic equipment:
Michina yekuvaka (excavator, loader)
Michina yekurima (combine harvester)
Industrial otomatiki:
Jekiseni kuumba muchina, kufa-kukanda muchina
Mhepo yemagetsi inosiyanisa pitch system
Aerospace:
Ndege inomhara giya hydraulic system
Mafambiro emusika uye mafambiro ekuvandudza mune ramangwana
1. Tekinoroji kubudirira kweaxial pombi
Kudzvinyirirwa kwepamusoro: Vamwe vagadziri (seBosch Rexroth naParker Hannifin) vakatangisa mazana matanhatu emabhara axial pombi kupikisa zvakanakira zvechinyakare zvepombi dzeradial.
Intelligent control: ma sensor akabatanidzwa kuti awane chaiyo-nguva kugadzirisa kwekuyerera uye kumanikidza (IoT hydraulic system).
2. Irreplaceability yemapombi eradial
Iyo 1000 bar + musika ichiri kutungamirwa nemapombi eradial, akadai seyekupedzisira-yakanyanya kudzvanywa mvura yekucheka uye yakakosha metallurgical midziyo.
Kufambira mberi kwezvinhu: ceramic plungers uye kabhoni faibha yakasimbiswa mabhomba inowedzera hupenyu.
3. Kudzivirirwa kwezvakatipoteredza uye simba rekugadzirisa zvinodiwa zvinofambisa hutsva
Mapombi eAxial anonyanya kuenderana nezvinodiwa zvekuchengetedza simba pasi pechinangwa che "dual carbon" nekuda kwehutano hwavo hwepamusoro-soro.
Mapombi eRadial awana nzvimbo nyowani dzekukura musimba rinodzokororwa (senge tidal power generation hydraulic systems).
Radial piston pombi uye axial piston pombi inomiririra huzivi huviri hwe hydraulic tekinoroji:
Mapombi eRadial "vatambi vesimba" vakagadzirirwa ultra-high pressure uye yakakwirira kuvimbika mamiriro;
Mapombi eAxial "vatambi vese-kutenderera" vane hunyanzvi, kudzoreka uye compactness.
Kana iwe uine chero zvaunoda, ndapota taura poocca hydraulic mugadziri.
