Hombe dhayamita sikweya pombi, ine mhango chikamu, inoshandiswa zvakanyanya sepombi yekufambisa mvura

Semapaipi ekutakura oiri, gasi rechisikigo, gasi, mvura uye zvimwe zvinhu zvakasimba. Kuenzaniswa nesimbi yakasimba senge simbi yakatenderedzwa, simbi pombi ine kukotama kwakafanana uye kusimba kwehuremu uye kureruka. Icho chikamu chehupfumi chesimbi. Inoshandiswa zvakanyanya mukugadzira zvikamu zvezvimiro uye mekiniki zvikamu, senge pombi yekuchera oiri, mota yekufambisa shaft, bhasikoro furemu uye simbi scaffold inoshandiswa mukuvaka. Kugadzira zvikamu zvemhete nemapombi esimbi zvinogona kuvandudza kushandiswa kwezvinhu, kurerutsa maitiro ekugadzira, uye kuchengetedza zvinhu uye maawa ekugadzirisa, senge kutenderedza mabheji mhete, Jack sleeves, nezvimwewo mapaipi esimbi ave achishandiswa zvakanyanya pakugadzira. Simbi pombi zvakare chinhu chakakosha kune ese marudzi ezvombo zvakajairika. Pfuti mbiya uye mbiya inofanira kugadzirwa nesimbi pombi. Simbi pombi inogona kukamurwa kuita denderedzwa pombi uye yakakosha-yakaumbwa pombi zvinoenderana neyakasiyana-muchinjika-chikamu nzvimbo uye chimiro. Nemhaka yokuti nzvimbo yedenderedzwa ndiyo yakakura pasi pemamiriro ekuenzana kwedenderedzwa, mvura yakawanda inogona kutakurwa nepombi yedenderedzwa. Mukuwedzera, apo chikamu chemhete chinoiswa pasi pemukati kana kunze kwekumanikidzwa kwemagetsi, simba rinowedzera kufanana. Nokudaro, pombi zhinji dzesimbi mapaipi akatenderera. Zvisinei, pombi yedenderedzwa inewo zvimwe zvinogumira. Semuenzaniso, pasi pemamiriro ekukotama kwendege, simba rekukotama repombi yedenderedzwa haina kusimba seyoyo yesquare uye rectangular pombi. Mapaipi emativi uye rectangular anowanzo shandiswa muchimiro chemimwe michina yekurima uye maturusi uye simbi nehuni fenicha. Mapaipi esimbi akakosha ane mamwe maumbirwo echikamu anodiwawo zvinoenderana nezvinangwa zvakasiyana.

Kukanganisa kwakawanda kwesquare chubhu kunokonzereswa mukupwanya, saka nzira yekufambisa simba yesquare chubhu isina chinhu ndiyo nzira yakakosha yekugadzira square chubhu. Iko kuoma kukuru kwekutsvaira kwealloy yakakwira kuri mukuderera kwekuita. Kuti uve nechokwadi chemhando, zvinodikanwa kuti usarudze zvine hungwaru maparamendi e deformation ye perforation. Kutsikirira kudiki kunokonzeresa kusagadzikana mukuita perforation, saka kana iyo yakakosha compression iri diki, plug inofanira kunge iri kumberi, uye kudzvanya kunowanzo kugadzika pa7%, zvikasadaro haizoruma, kana kutowedzera kufamba kana kuwana. rakanamira kumberi. Kuwedzera kwekumanikidza kumberi kweplug kuchagadzirawo gomba gomba uye kunyura zvikanganiso mukurira. Nokudaro, kana iwe uchida kugadzirisa dambudziko rebasa revatengi, pombi isina chinhu inofanira kuiswa pakati, uye kudzika kusina chinhu kwepakati kunofanira kuenzaniswa maererano nemamwe magiredhi esimbi. Naizvozvo, iyo yekudziya sisitimu ndiyo tembiricha yekubuda uye zvinodiwa zvekudziya mhando. Hunhu hwekudziya hunoenderana zvakanyanya nekudziya kwekushanda uye kudziyisa system. Iyo diki ellipality coefficient inowanzo vandudza kunaka kwecapillary uye kudzikamisa iyo transverse deformation. Nekudaro, iyo ellipse coefficient idiki zvakanyanya, izvo zvinokonzeresa kuomerwa kwekutenderedza chidimbu kutenderera, uye kunyange kutungamirira pakupfeka kwegiyadhi ndiro, izvo zviri nyore kukonzera kukanganisa pamusoro. Naizvozvo, kupfeka kwendiro yekutungamira kunofanirwa kutariswa kazhinji kana ngarava ichisunga sikweya pombi. Kana yangowanikwa, inofanira kuchinjwa pakarepo. Dhigirii reellipse rinofanira kudzorwa mukati meiyo 1.07-1.08. Iyo inokanganisa kushanda kwakajairwa kweanotevera maitiro, pamwe neakakosha maitiro ekudziya square chubhu isina chinhu, iyo zvakare ine simba guru pamhando yezvigadzirwa zvakapedzwa.
