Mfundo yosindikiza ya kulongedza makamaka imadalira mphamvu ya labyrinth ndi zotsatira zake.

Zotsatira za maze: Pansi pa shaft yocheperako pang'ono kwambiri, ndipo imatha kukwanira pang'ono ndikulongedza, koma osalumikizana ndi mbali zina. Chifukwa chake, pali kusiyana kakang'ono pakati pa kulongedza ndi kutsinde, ngati maze, ndipo sing'anga yopanikizidwa ili mumpata. Imagwedezeka kangapo kuti ikwaniritse kusindikiza.

Kugwira ntchito: Padzakhala filimu yopyapyala yamadzimadzi pakati pa kulongedza ndi tsinde, zomwe zimapangitsa kulongedza ndi kutsinde kukhala kofanana ndi mayendedwe otsetsereka ndipo imasewera mphamvu inayake yamafuta, motero kupewa kuvala kwambiri kwa kulongedza ndi kutsinde.

Zofunikira pakunyamula: Chifukwa cha kutentha, kupanikizika, ndi PH ya sing'anga yosindikizidwa, komanso kuthamanga kwa mzere, roughness pamwamba, coaxiality, kuthamanga kwa radial, eccentricity ndi zinthu zina za axially. nkhani yogawa pompa, zinthu zonyamula zimayenera kukhala ndi izi:

1. Ali ndi mlingo wina wa elasticity ndi pulasitiki

2. Kukhazikika kwamankhwala

3. Kusatha

4. Kudzipaka mafuta

5. Kutentha kukana

6. Zosavuta kusokoneza ndi kusonkhanitsa

7. Zosavuta kupanga komanso zotsika mtengo.

Zomwe zili pamwambazi zimakhudza mwachindunji ntchito yosindikiza ndi moyo wautumiki wa kulongedza, ndipo pali zipangizo zochepa zomwe zingathe kukwaniritsa zonse zomwe zili pamwambapa. Chifukwa chake, kupeza zida zosindikizira zapamwamba kwambiri ndikuwongolera zinthu zawo zakuthupi nthawi zonse kwakhala cholinga cha kafukufuku pankhani yosindikiza.

Kugawika, kapangidwe ndi kagwiritsidwe kazolongedza  mapampu axially split case .

Chifukwa cha zinthu zosiyanasiyana zogwirira ntchito, pali mitundu yambiri yazinthu zonyamula katundu. Kuti tisiyanitse bwino ndikusankha kulongedza, nthawi zambiri timagawa kulongedza molingana ndi zinthu zapakatikati zosindikizira:

1. Natural CHIKWANGWANI kulongedza katundu. Kulongedza kwa ulusi wachilengedwe kumaphatikizapo thonje lachilengedwe, nsalu, ubweya, ndi zina zotere monga zida zosindikizira.

2. Maminolo CHIKWANGWANI kulongedza katundu. Kulongedza kwa mamineral fiber kumaphatikizapo kulongedza kwa asibesitosi, ndi zina.

3. Zopangira CHIKWANGWANI kulongedza katundu. Synthetic CHIKWANGWANI kulongedza katundu makamaka zikuphatikizapo: graphite kulongedza, mpweya CHIKWANGWANI kulongedza katundu, PTFE kulongedza, Kevlar kulongedza, akiliriki-clip silikoni CHIKWANGWANI kulongedza, etc.

4. Ceramic ndi zitsulo CHIKWANGWANI kulongedza Chitsulo ndi zitsulo CHIKWANGWANI kulongedza makamaka monga: silicon carbide kulongedza, boron carbide kulongedza, sing'anga-alkali galasi CHIKWANGWANI kulongedza katundu, etc. CHIKWANGWANI chimagwiritsidwa ntchito kuluka kunyamula. Popeza pali mipata pakati pa ulusi wonyamula, ndizosavuta kuyambitsa kutayikira. Nthawi yomweyo, ulusi wina umakhala ndi mphamvu zodzitchinjiriza zokha komanso zimagundana kwambiri, motero zimafunika kuyikidwa ndi zofukiza ndi zodzaza. ndi zina zapadera, etc. Kupititsa patsogolo kachulukidwe ndi lubricity wa filler, monga: mafuta mchere kapena molybdenum disulfide mafuta wothira graphite ufa, talc ufa, mica, glycerin, masamba mafuta, etc., ndi impregnated polytetrafluoroethylene kupezeka emulsion, ndi mu Onjezani kuchuluka koyenera kwa ma surfactants ndi dispersants ku emulsion. Zowonjezera zapadera nthawi zambiri zimakhala ndi zinc particles, barrier agents, molybdenum-based corrosion inhibitors, etc.
