Mundima yemavharuvhu emaindasitiri, mavharuvhu emashavishavi anoshandiswa zvakanyanya mumaindasitiri akasiyana-siyana akadai semafuta negesi, kurapwa nemvura, kugadziriswa kwemakemikari, nezvimwewo. Pakati pemhando dzakasiyana dzemavharuvhu emashavishavi, mhando mbiri dzinotungamira: vharuvhu yemashavishavi maviri e eccentric uye vharuvhu yemashavishavi matatu e eccentric. Mukuenzanisa uku kwakazara, tichatarisa zvakadzama dhizaini, zvakanakira, zvakaipira uye mashandisirwo emavharuvhu maviri aya.
Vharuvhu yeshavishavi yekudzikisa kaviri
Sezvinoratidzwa nezita racho, mavharuvhu ebhururu ane mavharuvhu maviri ane mavharuvhu maviri: mavharuvhu ekutanga ndiwo musanganiswa weshaft, kureva kuti, musanganiswa we shaft axis kubva pakati pepombi, uye musanganiswa wechipiri ndiwo musanganiswa we seal, kureva kuti, chimiro chechisimbiso chevharuvhu. Dhizaini iyi ine zvakanakira nekuipira kukuru.
Mabhenefiti evharuvhu yeshavishavi ine eccentric mbiri
1. Kusapfeka zvakanaka
Chinangwa chekugadzira shaft eccentricity ndechekuderedza kukweshana pakati pevharuvhu nechigaro chevharuvhu panguva yekuvhura nekuvhara, nokudaro zvichideredza kupfeka uye kuderedza njodzi yekubuda kwemvura. Zvinogona zvakare kuwedzera hupenyu hwevharuvhu yeshavibhuruvhu uye kuderedza mari yekugadzirisa.
2. Kusimbiswa kwakawedzerwa
Kusanzwisisika kwechipiri kunoita kuti nzvimbo yekuvharira ibatane nechigaro chevharuvhu chete padanho rekupedzisira rekuvhara, izvo zvisingangovimbise chete chisimbiso chakasimba, asiwo zvinodzora zvinobudirira nzira yacho.
3. Kudzikira kwesimba remagetsi
Dhizaini ye "double offset" inoderedza "friction coefficient", izvo zvinoderedza simba rinodiwa kuti vharuvhu yebhatafurayi ivhurwe uye ivharwe.
4. Kuvhara mativi maviri
Mavharuvhu maviri eshavishavi asina kusimba anogona kuvhara mativi maviri, zvichiita kuti kuyerera kwemativi maviri kuenderere mberi, uye zviri nyore kuisa nekushandisa.
Zvakashata zvemavharuvhu maviri e eccentric butterfly:
1. Mutengo wakakwira
Dhizaini yepamusoro uye zvinhu zvemavharuvhu eshavishavi maviri anoshamisa zvinowanzoita kuti mitengo yekugadzira ikwire zvichienzaniswa nemavharuvhu eshavishavi epakati.
2. Kurasikirwa kwesimba remvura kwakawanda
Nekuda kweplate yevharuvhu yakakora kaviri, chigaro chevharuvhu chinobuda, uye nzira dzakamanikana, kumanikidzwa kwemvura kuburikidza nevharuvhu yeshavishavi kunogona kuwedzera.
3. Kupisa kwakaganhurirwa
Mavharuvhu maviri eshavishavi anogona kunge asina kusimba pakubata tembiricha yakaderera kana tembiricha yepamusoro nekuti zvinhu zvinoshandiswa zvinogona kusakwanisa kutsungirira tembiricha yakanyanya.
Vharuvhu yeshavishavi yeKubvisa Katatu
Vharuvhu yeshavishavi ine triple offset inomiririra kuvandudzwa kwedhizaini yevharuvhu yeshavishavi ine mativi matatu. Zvichibva pachimiro chechimiro chekaviri, chimiro chechitatu chekatatu ichikamu chepakati chevharuvhu zvichienzaniswa nepakati pemuviri wevharuvhu. Dhizaini iyi itsva inobatsira zvikuru pane vharuvhu yeshavishavi yepakati pepakati.
Mabhenefiti emavharuvhu eshavishavi ane eccentric matatu
1. Kusabuda kwemvura zvachose
Chimiro chakasiyana chechinhu chinovhara vharuvhu reshavishavi rine hunyanza hutatu chinobvisa kukweshana nekusakara, zvichikonzera kuvharwa kwakasimba muhupenyu hwese hwevharuvhu.
2. Kupisa kwakanyanya uye kuramba kumanikidzwa kwakanyanya
Vharuvhu yeshavishavi ine simbi yese ine mativi matatu uye vharuvhu yeshavishavi ine mativi akawanda inogona kubata tembiricha yakakwira uye mvura inomanikidzwa zvakanyanya.
3. Dhizaini isingatsvi
Zvinhu zvese zvevharuvhu yemashavishavi matatu eccentric zvinogona kusangana nezvinodiwa zvakasimba zvisingatsvi, zvichiita kuti ive yakanaka mukushandiswa kusingatsvi.
4. Kudzika kwesimba uye kukweshana
Vharuvhu yemashavishavi ine mativi matatu inogona kuderedza torque yekushanda nekukweshana, nokudaro zvichiita kuti ishande zvakanaka, ichideredza torque uye ichirebesa hupenyu hwebasa.
5. Mhando dzakasiyana dzemashandisirwo
Vharuvhu yemashavishavi ine mativi matatu yakanakira kushandiswa kwakasiyana-siyana, kusanganisira mafuta negesi, petrochemical, kugadzira magetsi uye maindasitiri ekuchenesa.
Zvakaipa zvemavharuvhu eshavishavi ane eccentric matatu
1. Mutengo wakakwira
Vharuvhu yemashavishavi ine mativi matatu inowanzova nemutengo wakakwira wekugadzira kwekutanga nekuda kwekugadzirwa kwayo kwepamusoro uye chimiro chayo.
2. Kurasikirwa nemusoro kwakanyanya
Kuwedzerwa kwekuwedzera kwekugadzirwa kwe "triple eccentric" kunogona kukonzera kurasikirwa kwemusoro kwakanyanya zvishoma pane vharuvhu ine "double eccentric".
Vharuvhu yeshavishavi ine eccentric kaviri VS vharuvhu yeshavishavi ine eccentric katatu
1. Chigaro chevharuvhu
Chigaro chevharuvhu chevharuvhu ine mativi maviri akaenzana chinowanzoiswa mumugero uri pavharuvhu uye chakagadzirwa nerabha senge EPDM, saka chinogona kuvharwa nemhepo, asi hachina kukodzera kushandiswa pakupisa kwakanyanya. Chigaro chevharuvhu chevharuvhu ine mativi matatu akaenzana chine simbi yese kana kuti chine mativi akawanda, saka chakakodzera zvakanyanya kupisa kwakanyanya kana mvura inoparadza.
2. Mutengo
Ingava mari yekugadzira kana kuoma kwemaitiro ekugadzira, mavharuvhu emabhatafura ane mativi matatu akakwirira kupfuura mavharuvhu emabhatafura ane mativi maviri. Zvisinei, kuwanda kwemavharuvhu emabhatafura ane mativi matatu akaderera pane mavharuvhu emabhatafura ane mativi maviri.
3. Torque
Chinangwa chekutanga chedhizaini yevharuvhu remashavishavi rine mativi matatu ndechekuderedza kupera nekukweshana. Nokudaro, simba revharuvhu remashavishavi rine mativi matatu rakaderera pane vharuvhu remashavishavi rine mativi maviri.
