Rudzi rwemumugwagwa runotenderera, runozivikanwawo se earth roller, imhando yemichina yekugadzirisa migwagwa. Rudzi rwemumugwagwa rwuri muchikamu chemichina yeinjiniya, uye runoshandiswa zvakanyanya mukuzadza nekusimbaradza mapurojekiti makuru einjiniya akadai semigwagwa mikuru, njanji, nzira dzendege, madhamu, nhandare dzemitambo, nezvimwewo. Runogona kukwiza ivhu rine jecha, rakasanganiswa zvishoma uye rakasanganiswa, kudzvanya ivhu rakagadzikana, uye asphalt concrete pavement layers. Rudzi urwu runoiswa pamabasa akasiyana-siyana ekusimbaradza nehukuru hwemuchina wacho, kuitira kuti rudzi rwakamanikana ruve rwakakanganisika uye rwakamanikana zvachose. Chimiro chevhiri rinotenderera chinosanganisira roller yakatsetseka, roller yekudyisa uye roller yemakumbo emakwai. Roller yakatsetseka ndiyo inonyanya kushandiswa, inonyanya kushandiswa pakusimbisa pamusoro penzira. Kutumirwa kwemuchina kana hydraulic kunoshandiswa, kunogona kutarisa pakusimbisa zvikamu zvinobuda, zvine kusimba kwakanyanya, uye kwakakodzera pakusimbisa pavement yeasphalt.
Chii chinoshanda neroller kutsigira hydraulic rod? Roller inotsigira roller inogona kushandiswa kutsigira kukwirira. Inoshandisa acompression mhando gasi chitubu, iyo inonyanya kukanganiswa nesimba rinogadzirwa nekumanikidzwa kwegasi. Chitsigiro chemuchina wekufambisa mugwagwa chine chitubu chemhepo chakamanikidzwa. Nheyo yacho ndeyekuti kana simba riri pachitubu rakakura, nzvimbo iri mukati mechitubu ichaderera, uye mhepo iri mukati mechitubu ichamanikidzwa nekudzvanywa. Kana mhepo yakamanikidzwa kusvika pamwero wakati, ichaburitsa simba rinonamira. Panguva ino, chitubu chichakwanisa kudzoreredza chimiro chisati chashanduka, kureva chimiro chepakutanga. Chitubu chemhepo chakamanikidzwa chinogona kutamba basa rakanaka rekutsigira, pamwe nebasa rakanaka rekuvhara nekubhureka. Uyezve, chitubu chemhepo chakamanikidzwa chinogonawo kutamba basa rakasimba mukugadzirisa makona uye kunyudzwa kweshock.
GuangzhouTieying Gas Spring Technology Co., Ltdine ruzivo rwemakore makumi maviri mukugadzira zvitubu zvegasi. Ine timu yayo yekugadzira. Hunhu uye hupenyu hwebasa reTieying Spring hunodarika ka200000. Hapana kuyerera kwegasi, hapana kuyerera kwemafuta, uye hapana matambudziko mushure mekutengesa. Kana uchida kuziva zvakawanda nezvekushandiswa kwechitubu chegasi, ndapota taura nesu!
