1. Wedzera chisimbiso chemafuta

Kune mavharuvhu asingashandise mafuta ekuvharira, funga nezvekuwedzera mafuta ekuvharira kuti uvandudze mashandiro ekuvhara tsinde revharuvhu.

2. Wedzera chizere

Kuti pave nekushanda kwakanaka kwekusunga chivharo chevharuvhu, nzira yekuwedzera chivharo inogona kushandiswa. Kazhinji, mafillers akasanganiswa ane layer mbiri kana multi-layer anoshandiswa. Kungowedzera huwandu, sekuwedzera nhamba kubva pazvidimbu zvitatu kusvika pazvidimbu zvishanu, hazvizove nemigumisiro yakajeka.

3. Tsiva girafu yegirafu

Kurongedza kwePTFE kunoshandiswa zvakanyanya kune tembiricha yekushanda iri pakati pe -20 kusvika +200°C. Kana tembiricha ikachinja zvakanyanya pakati pemiganhu yepamusoro neyakaderera, mashandiro ayo ekuvharira anodzikira zvakanyanya, ichakwegura nekukurumidza uye hupenyu hwayo huchava hupfupi.

Zvishandiso zve graphite zvinochinjika zvinokunda zvikanganiso izvi uye zvinogara kwenguva refu. Nokudaro, mamwe mafekitori akachinja zvese zvePTFE packing kuita graphite packing, uye kunyange mavharuvhu ekudzora achangotengwa akashandiswa mushure mekutsiva PTFE packing ne graphite packing. Zvisinei, hysteresis yekushandisa graphite filler yakakura, uye dzimwe nguva kukambaira kunoitika pakutanga, saka kufunga nezveizvi kunofanira kupihwa.

4. Chinja nzira yekuyerera kwemvura woisa P2 kumagumo evharuvhu.

Kana △P yakakura uye P1 yakakura, kuvhara P1 kwakaoma kupfuura kuvhara P2. Nokudaro, nzira yekuyerera inogona kuchinjwa kubva paP1 kumagumo evharuvhu kuenda kuP2 kumagumo evharuvhu, izvo zvinoshanda zvakanyanya kumavharuvhu ane kumanikidzwa kwakanyanya uye musiyano mukuru wekumanikidzwa. Semuenzaniso, mavharuvhu ebellows anowanzo funga nezvekuvhara P2.

5. Shandisa gasket sealing ye lens

Pakuvhara mavharuvhu epamusoro nepazasi, kuvhara chigaro chevharuvhu uye miviri yevharuvhu yepamusoro nepazasi. Kana chiri chisimbiso chakati sandara, kana tembiricha yakakwira uye kumanikidzwa kwakanyanya, kushanda kwechisimbiso kwakashata, zvichikonzera kubuda kwemvura. Unogona kushandisa chisimbiso chegasket chelens panzvimbo pezvo, chinogona kuwana mhedzisiro inogutsa.

6. Tsiva gasket rekuvhara

Kusvika pari zvino, magasket mazhinji ekuvhara achiri kushandisa mabhodhi easbestos. Pakupisa kwakanyanya, mashandiro ekuvhara haana kunaka uye hupenyu hwebasa hupfupi, zvichikonzera kubuda kwemvura. Muchiitiko ichi, unogona kushandisa magasket espiral wound, "O" rings, nezvimwewo, izvo mafekitori mazhinji agara achishandisa.

7. Simbisa mabhaudhi zvakaenzana wovhara nemagasket matete

Muchivako chevharuvhu chinodzora chine "O" ring seal, kana magaskets akakora ane deformation yakakura (senge ma winding sheets) akashandiswa, kana compression isina kuenzana uye simba risina kuenzana, chisimbiso chichakuvara, kutsveyama uye kukanganisika zviri nyore. Zvinokanganisa zvakanyanya mashandiro e sealing.

Saka, pakugadzirisa nekubatanidza rudzi urwu rwevharuvhu, mabhoti ekumanikidza anofanira kusimbiswa zvakaenzana (cherechedza kuti haagone kusimbiswa panguva imwe chete). Zvingava nani kana gasket gobvu ikachinjwa kuita gasket tete, izvo zvinogona kuderedza nyore nyore kutsvedza uye kuve nechokwadi chekuvharwa.

8. Wedzera upamhi hwechisimbiso pamusoro

Chikamu chevharuvhu chakati sandara (senge chivharo chevharuvhu ine nzvimbo mbiri nevharuvhu yemaoko) hachina nzvimbo yakakombama inotungamirwa nemutungamiri muchigaro chevharuvhu. Kana vharuvhu iri kushanda, chikamu chevharuvhu chinoshandiswa nesimba repadivi uye chinobuda kubva munzira inopinda. Chidimbu, kana mukaha wepakati pevharuvhu wakakura, chiitiko ichi chedivi rimwe chete chichava chakakomba zvikuru. Pamusoro pezvo, kuchinja, kusabatanidzwa, kana kupwanyika kudiki kwechikamu chevharuvhu (kazhinji 30° chamfering yekutungamira) kuchaita kuti chikamu chevharuvhu chivharwe kana chave pedyo nekuvhara. Chiso chechamfered chinoiswa pamusoro pechigaro chevharuvhu, zvichiita kuti chikamu chevharuvhu chisvetuke kana chavhara, kana kutorega kuvhara zvachose, zvichiwedzera kubuda kwevharuvhu zvakanyanya.

Mhinduro iri nyore uye inoshanda zvikuru ndeyekuwedzera saizi yenzvimbo yekuvharira vharuvhu, kuitira kuti dhayamita shoma yenzvimbo yekuvharira vharuvhu ive diki ne1 kusvika 5 mm pane dhayamita yechigaro chevharuvhu, uye ive negwara rakakwana rekuona kuti nzvimbo yekuvharira vharuvhu yatungamirirwa muchigaro chevharuvhu uye inoramba iine hukama hwakanaka hwenzvimbo yekuvharira.
