Iyo yekuisa chisimbiso yekurongedza inonyanya kuenderana neiyo labyrinth mhedzisiro uye yekubereka mhedzisiro.

Maze maitiro: Iyo microscopic yakadzika pasi peshaft haina kuenzana, uye inogona kungokwana chikamu pamwe nekurongedza, asi haina kusangana nezvimwe zvikamu. Naizvozvo, pane mukaha mudiki pakati pekurongedza uye shaft, senge maze, uye iyo yakamanikidzwa svikiro iri mugomba. Inodzvinyirirwa kakawanda kuti iwane iyo yekuisa chisimbiso.

Kutakura mhedzisiro: Pachave neyakaonda yemvura firimu pakati pekurongedza uye shaft, iyo inoita kuti kurongedza uye shaft zvifanane nemabhengi ekutsvedza uye inoridza imwe yekuzora maitiro, nekudaro kudzivirira kupera kwakanyanya kwekurongedza uye shaft.

Kurongedza zvinhu zvinodiwa: Nekuda kwekushisa, kudzvanywa, uye PH yepakati yakavharwa, pamwe nekumhanya kwemutsara, kushata kwepamusoro, coaxiality, radial runout, eccentricity uye zvimwe zvinhu zveaxially. split case pombi, iyo yekurongedza inodiwa kuti ive neanotevera maitiro:

1. Iine mwero wakati we elasticity uye plastiki

2. Chemical kugadzikana

3. Kusapinda

4. Kuzvizora

5. Kuramba kwekushisa

6. Zviri nyore kuparadzanisa uye kuunganidza

7. Nyore kugadzira uye yakaderera mumutengo.

Zvinhu zviri pamusoro apa zvinokanganisa kushanda kwechisimbiso uye hupenyu hwebasa rekurongedza, uye pane zvishoma zvinhu zvinogona kusangana zvizere nezvose zviri pamusoro apa. Naizvozvo, kuwana zvemhando yepamusoro zvekuvharisa zvinhu uye kuvandudza zvivakwa zvavo zvenyama kwagara kuri kutarisisa kwekutsvaga mundima yekuisa chisimbiso.

Kurongeka, kuumbwa uye kushandiswa kwekurongedza  axially split kesi pombi .

Nekuda kwemamiriro akasiyana ekushanda, kune akawanda marudzi ekutakura zvinhu. Kuti tinyatso kusiyanisa uye kusarudza kurongedza, isu tinowanzo kupatsanura kurongedza zvinoenderana nechinhu cheiyo huru yekuisa chisimbiso base zvinhu zvekurongedza:

1. Natural fiber packing. Natural fiber packing inonyanya kusanganisira yedonje yechisikigo, yerineni, makushe, nezvimwewo sechisimbiso chepasi zvinhu.

2. Mineral fiber packing. Mineral fiber packing inonyanya kusanganisira asbestos kurongedza, nezvimwe.

3. Synthetic fiber packing. Synthetic fiber packing inonyanya kusanganisira: graphite kurongedza, kabhoni faibha kurongedza, PTFE kurongedza, Kevlar kurongedza, acrylic-clip silicone fiber packing, nezvimwe.

4. Ceramic nesimbi fiber packing Ceramic uye simbi fiber packing inonyanya kusanganisira: silicon carbide packing, boron carbide packing, medium-alkali girazi fiber packing, etc. Sezvo imwe fiber zvinhu ine zvakawanda kana zvishoma zvimwe zvinhu pachavo Izvo zvakashata ndezvekuti imwe chete. fiber inoshandiswa kuruka kurongedza. Sezvo paine mikaha pakati pemafibhi ekutakura, zviri nyore kukonzera kuvuza. Panguva imwecheteyo, mamwe mafiibhi ane hurombo hwekuzvinyudza uye yakakura friction coefficient, saka inoda kuisirwa mamwe mafuta uye mafiritsi. uye akakosha ekuwedzera, etc. Kuvandudza density uye lubricity yekuzadza, senge: mineral oil kana molybdenum disulfide girisi yakasanganiswa negraphite powder, talc powder, mica, glycerin, mafuta emiriwo, nezvimwewo, uye impregnated polytetrafluoroethylene dispersion emulsion, uye mu Wedzera huwandu hwakakodzera hwema surfactants uye dispersants kune emulsion. Special additives zvinowanzo sanganisira zinc particles, barriers agents, molybdenum-based corrosion inhibitors, nezvimwewo kuderedza kukora kwemidziyo kunokonzerwa nekurongedza mafirita.
