Sarudzo yeaizi yekuchengetedza system vharafu Unoziva zvipi zvekuvhara mavharuvhu? Ndeapi maitiro echinhu chekuisa chisimbiso?
Kusarudzwa kwevhavha kunofanirwa kutarisa kune dambudziko:
(1) magetsi ekudzora vharafu, chinja vharavhavha yekuisa chisimbiso kuita kunofanirwa kuve kwakasimba nekuita kwechando uye kunyunguduka, ethylene glycol divi mune imwe nhanho inomhanya pa2.19 ℃ / 5.56 ℃ tembiricha yemhando, kune rimwe divi rendiro mune inotonhora. mvura mu12 ℃, 7 ℃ / kazhinji inomhanya, kana bhodhi iri muethylene glycol parutivi yakavharwa lax yekudonha, ichaita kuti ndiro iri mumvura yakaomeswa chando kuoma kune rimwe divi, Kuomesa-kutsemuka michina.
(2) Ivhavha yekuongorora uye bypass valve inofanira kuiswa kumativi ose evhavha yemagetsi; Yekuchengetedza system, uye kushanda kwemaoko.
Ivhavha yemagetsi inofanirwa kunge iine yakanakira bhuku rekugadzirisa mudziyo.
Unoziva here kuti zvii zvekuvhara mavharuvhu? Ndeapi maitiro echinhu chekuisa chisimbiso?
Nheyo yekuvhara vharafu
Kuisa chisimbiso kudzivirira kuvuza, saka musimboti wekuvharisa vharafu zvakare kubva pakudzivirira kuvuza kutsvagisa. Pane zvinhu zviviri zvikuru zvinokonzera kuvuza. Chimwe ndicho chinhu chikuru chinokanganisa mashandiro ekuisa chisimbiso, ndiko kuti, pane mukaha pakati pevaviri vanoisa chisimbiso, uye chimwe ndechekuti pane mutsauko wekumanikidza pakati pemativi maviri echisimbiso. Nheyo yekuisa chisimbiso yevharuvhu iri zvakare kubva kumvura yekuisa chisimbiso, gasi chisimbiso, leakage chiteshi chekuisa chisimbiso uye vharafu sealing peya uye zvimwe zvina zvinhu zvekuongorora.
01 Kusimba kwemvura
Kusimba kwemvura kunotariswa nekupenya kwayo uye kusimba kwepamusoro. Kana vharafu ichibuda capillary yakazadzwa negasi, kudzvanya kwepamusoro kunogona kudzosera kana kudhirowa mvura mucapillary. Uye izvo zvinogadzira tangent Angle. Kana iyo tangent Angle isingasviki makumi mapfumbamwe, mvura inoiswa mucapillary chubhu uye kubuda kunoitika. Chikonzero chekudonha chiri mumhando dzakasiyana dzepakati. Edza nenhau dzakasiyana, pasi pemamiriro akafanana, uchawana mhinduro dzakasiyana. Unogona kushandisa mvura, mhepo, parafini, etc. Kana iyo tangent Angle yakakura kupfuura 90, kuvuza kuchaitika zvakare. Nekuda kwehukama nemafuta kana wakisi firimu pamusoro pesimbi. Kana aya mafirimu epamusoro anyungudutswa, hunhu hwesimbi inoshanduka, uye mvura, iyo yaimbodzingwa, inonyorovesa pamusoro nekudonha. Tichifunga nezve mamiriro ari pamusoro, maererano nePoisson's formula, chinangwa chekudzivirira kudonha kana kuderedza kudonha kunogona kuitika pasi pemamiriro ekudzikisa capillary dhayamita uye yepakati viscosity.
2 Gasi tightness
Zvinoenderana neformula yaPoisson, kusimba kwegasi kune hukama nemamorekuru egasi uye gasi viscosity. Kudonha kunopesana nekureba kwecapillary uye viscosity yegesi, uye yakaenzana nedhayamita ye capillary uye simba rekutyaira. Kana iyo dhayamita ye capillary uye avhareji madhigirii ekusununguka kwemamorekuru egasi akafanana, mamorekuru egasi anoyerera achipinda mucapillary nemahara emafuta ekufamba. Naizvozvo, kana tichiita bvunzo yekuisa chisimbiso chevhavha, iyo yepakati inofanira kunge iri mvura kuita basa rekuisa chisimbiso, nemhepo kana gasi haigone kuita basa rekuisa chisimbiso. Kunyange kana tikaderedza capillary dhayamita pazasi gasi molecule kubudikidza epurasitiki deformation, kuyerera kwegasi haigoni kumiswa. Chikonzero ndechekuti gasi rinogona kuramba richipararira kuburikidza nemadziro esimbi. Saka kana tichiita gasi bvunzo, isu tinofanirwa kuve takasimba kupfuura bvunzo yemvura.
3 Chisimbiso musimboti yekuvuza chiteshi
Chisimbiso chevharuvhu chinoumbwa nezvikamu zviviri, roughness, iyo inoumbwa nekukasharara kwekusaenzana kwakapararira pane waveform surface uye kusimuka kwechinhambwe pakati pezvikomo. Pasi pemamiriro ekuti simba rekumanikidza rezvinhu zvakawanda zvesimbi rakaderera munyika yedu, isu tinofanirwa kukwidza zvinodikanwa zvekumanikidza kwesimba resimbi, ndiko kuti, simba rekumanikidza rezvinhu rinofanira kudarika elasticity, kana tichida kuwana sealing state. Naizvozvo, mukugadzirwa kwevharuvhu, peya yekuisa chisimbiso yakasanganiswa neimwe kuoma kwakasiyana kuti ienderane, pasi pekuita kwekumanikidza, inoburitsa imwe dhigirii yepurasitiki deformation sealing effect. Kana iyo yekuisa chisimbiso iri simbi zvinhu, ipapo pamusoro peiyo isina kuenzana convex poindi ichaonekwa kare, pakutanga chete nemutoro mudiki unogona kuita aya asina kuenzana convex point epurasitiki deformation. Kana iyo yekubatana ikawedzera, kusaenzana kwepamusoro kuchava epurasitiki - elastic deformation. Ipapo kushata kwezviso zviviri munzvimbo ine concave kuchavapo. Idzi nzira dzakasara dzinogona kugadzirwa kuti dzikwane kana mutoro unokonzera kukanganisa kwakanyanya kwepurasitiki yechinhu chiri pasi ichiiswa uye nzvimbo mbiri dziri pedyo nepedyo, pamwe nemutsara unoenderera uye munzira yemhete.
4. Valve sealing pair
Iyo valve seal pair ndiyo chikamu chechigaro chevharuvhu uye shutoff inovhara kana ichinge yasangana. Iyo simbi yekuisa chisimbiso pamusoro inokonzeresa kukuvadzwa kubva ku clamping media, media corrosion, kupfeka zvimedu, cavitation uye erosion panguva yekushandiswa. Zvakadai sokupfeka zvimedu. Kana zvimedu zvekupfeka zvidiki pane kushata kwepamusoro, iko kurongeka kwepamusoro kuchavandudzwa kana nzvimbo yekuisa chisimbiso ichiiswa mukati, uye haizoparari. Pane kudaro, ichaita kuti kurongeka kwepamusoro kuwedzere. Nokudaro, pakusarudzwa kwezvimedu zvekupfeka, zvinhu, mamiriro ekushanda, lubricity uye corrosion yenzvimbo yekuisa chisimbiso inofanira kutariswa zvakakwana. Sezvimedu zvekupfeka, patinosarudza zvisimbiso, tinofanira kunyatso funga zvinhu zvakasiyana-siyana zvinokanganisa mashandiro avo kuitira kuti titambe basa rekudzivirira kubuda. Naizvozvo, zvinhu zvinoramba kukoromoka, abrasion uye kuputika kunofanirwa kusarudzwa. Zvikasadaro, kushomeka kwechero ipi yezvinodiwa kuchaita kuti yekuisa chisimbiso kuita kwayo ** kuderedzwa.
2. Zvinhu zvikuru zvinokanganisa valve seal
Pane zvinhu zvakawanda zvinokanganisa chisimbiso chevhavha, kunyanya zvinotevera:
