Sarudzo yemakina chisimbiso chimiro chemhando idanho rakakosha mukugadzira maitiro, inofanirwa kuongorora kutanga:
1.Working parameters -Media pressure, tembiricha, shaft dhayamita uye nekukurumidza.
2. Hunhu huri pakati nepakati - fungidziro, viscosity, causticity, ine kana isina zvimedu zvakasimba uye tsvina yefiber, ingave iri nyore kunyungudutsa kana crystallization.
3. Mamiriro ekushanda kwemuenzi uye mamiriro ezvakatipoteredza - kuenderera mberi kana kushanda kwepakati; Mubati anoiswa mukamuri kana akafumurwa; Mamiriro ekunze akatenderedza zvivakwa uye tembiricha inoshanduka.
4. Iyo mauto echisimbiso kubvumira kuvuza, kudonhedza kutungamira (kudonha kwemukati kana kubuda kwekunze) zvinodiwa; Hupenyu uye kuvimbika zvinodiwa.
5. Kubata pahukuru hwezvisimbiso zvimiro zvinorambidzwa.
6. Kushanda uye kugadzirwa kwemaitiro kugadzikana.
Chekutanga, maererano nekushanda paramita P, V, T sarudzo:
Pano P ndiyo kumanikidzwa kwepakati pane chisimbiso cavity.Zvichienderana nehukuru hweP kukosha, inogona kutanga yakatemwa kuti ingasarudza chimiro chakadzikama pamwe nechiyero chechiyero.Kune yepakati high viscosity, yakanaka lubricity, p ≤ 0.8MPa, kana yakaderera viscosity, yakashata lubricity yepakati, p ≤ 0.5MPa, kazhinji inoshandisa chimiro chisina kuenzana.Kana p kukosha inodarika chiyero chepamusoro, chimiro chekuenzanisa chinofanira kufungwa.Apo P ≥ 15MPa, iyo yakawanda-yekupedzisira-yekupedzisira yakarongeka yakaoma kuzadzisa zvinodiwa zvekuisa chisimbiso, panguva ino. inogona kushandiswa muakatevedzana akawanda-terminal chisimbiso.
U is the circumferential velocity yeavhareji yedhayamita yenzvimbo yakavharwa, uye inotarisa kuti elastic element inotenderera neaxis zvinoenderana nekukosha kwekukosha kweU, iko kushandisa chitubu chemhando yekutenderera kana chitubu chakaremerwa chimiro. isingasviki 20-30m / s inogona kushandiswa spring-type kutenderera, mamiriro ekumhanya kwepamusoro, nekuda kwekusagadzikana kwehutano hwezvikamu zvinotenderera zviri nyore kutungamirira kukudengenyeka kwakasimba, zviri nani kushandisa spring static structure.Kana kukosha kweP uye U. ese ari maviri akakwirira, funga nezve kushandiswa kweiyo hydrodynamic chimiro.
T inoreva tembiricha yepakati mukati mekamuri yakavharwa, zvichienderana nehukuru hweT kuona iyo yekubatsira yekuisa chisimbiso mhete, yekuisa chisimbiso pamusoro pekutonhora nzira uye yayo yekubatsira system.Temperature T panguva ye0-80 ℃ siyana, iyo yebetsero mhete ndiyo kazhinji inosarudzwa nitrile rubber O-ring; T pakati -50 — +150 ℃, maererano nekuora kwesimba re media, sarudzo yefluorine rabha, silicone rabha kana PTFE yekurongedza yekuzadza mhete iripo. Kana tembiricha yadzikira pane -50 kana yakakwirira kupfuura 150 ℃, rubber uye polytetrafluoroethylene ichabereka yakaderera tembiricha embrittlement kana tembiricha kuchembera, panguva ino inogona kushandiswa simbi mabhero chimiro.Apo turbidity yepakati yakakwirira kupfuura 80 ℃, zvinowanzofanira kuiona seyakakwirira. tembiricha mundima yekuisa chisimbiso, uye matanho ekutonhodza anoenderana anofanira kutorwa.
Chechipiri, kusarudzwa zvinoenderana nevezvenhau maitiro:
Corrosive weak medium, kazhinji inoshandisa yakavakirwa-mukati mechanical chisimbiso, kupera kwesimba rehurumende uye kutungamira kwe media media kunonzwisisika kana zvichienzaniswa nerudzi rwekunze. kunze kana polytetrafluoroethylene bellows mechanical chisimbiso, asi kazhinji inongoshanda chete P ≤ 0.2-0.3MPa range.Iri nyore kupenya, nyore kusimbisa uye yakakwirira viscosity yepakati, inofanira kushandisa imwe chitubu chinotenderera chimiro. ichakonzera diki spring axial compensation movement yakavharwa.Inopisa, inoputika, ine chepfu midhiya, kuitira kuti ive nechokwadi chokuti midhiya haidonhedzi, chimiro chakapedzwa kaviri chine sealant (isolation liquid) inofanira kushandiswa.
Zvinoenderana nezviri pamusoro apa maparamendi ekushanda uye midhiya maitiro echimiro chakasarudzwa chinowanzova chirongwa chekutanga, kutsunga kwekupedzisira kunofanirawo kufunga nezve hunhu hwemugamuchiri uye zvimwe zvakakosha zvinodiwa pakusunga chisimbiso. Semuyenzaniso, muenzi muchikepe dzimwe nguva ari muchikepe. kuti uwane nzvimbo yakanyatsoshanda, saizi yechisimbiso uye nzvimbo yekuisirwa zvinowanzoitwa zvakanyanya kuomesesa zvinodiwa.Mumwe muenzaniso ndewepasi pemvura papombi yemvura, mukukwira nekudzika kwepasi pemvura, kudzvanywa kunosiyana zvakanyanya.Muzviitiko izvi. , iyo yakajairwa dhizaini haigone kusarudzwa nguva nenguva, asi inofanirwa kugadzirwa zvakanyanya kune chaiyo mamiriro ekushanda, uye kutora matanho anodiwa.
