Umgaqo wokutywinwa wokupakisha ngokuyinhloko uxhomekeke kwimpembelelo ye-labyrinth kunye nefuthe lokuzala.

Isiphumo seMaze: Indawo esezantsi ye-microscopic yeshaft ayilingani kakhulu, kwaye inokulingana kuphela ngokupakisha, kodwa ayidibanisi namanye amalungu. Ke ngoko, kukho umsantsa omncinci phakathi kokupakisha kunye ne-shaft, njenge-maze, kwaye i-pressurized medium ikwi-gap. Ibethelwa amaxesha amaninzi ukufezekisa umphumo wokutywinwa.

Ukuthwala impembelelo: Kuya kubakho ifilimu encinci ye-liquid phakathi kokupakisha kunye ne-shaft, eyenza ukupakishwa kunye ne-shaft kufana neebheringi ze-sliding kwaye idlala umphumo othile wokuthambisa, ngaloo ndlela ugweme ukugqithisa ngokugqithiseleyo ukupakisha kunye ne-shaft.

Iimfuno zezinto zokupakisha: Ngenxa yobushushu, uxinzelelo, kunye ne-PH yendawo etywiniweyo, kunye nesantya somgca, uburhabaxa bomphezulu, i-coaxiality, i-radial runout, eccentricity kunye nezinye izinto ze-axially. ityala lokwahlula impompo, izinto zokupakisha ziyafuneka ukuba zibe nezi mpawu zilandelayo:

1. Unomlinganiselo othile wokunwebeka kunye neplastiki

2. Ukuzinza kweekhemikhali

3. Ukungangeni

4. Ukuzithambisa

5. Ukumelana nobushushu

6. Kulula ukuqhaqha kunye nokudibanisa

7. Kulula ukwenza kunye nexabiso eliphantsi.

Iimpawu eziphathekayo ezingentla zichaphazela ngokuthe ngqo ukusebenza kokutywinwa kunye nobomi benkonzo yokupakisha, kwaye kukho izinto ezimbalwa kakhulu ezinokuhlangabezana ngokupheleleyo nazo zonke ezi zakhiwo zingentla. Ngoko ke, ukufumana izinto zokutywinwa ezikumgangatho ophezulu kunye nokuphucula iimpawu zabo eziphathekayo bekusoloko kugxininisekile kuphando kwintsimi yokutywinwa.

Ukuhlelwa, ukubunjwa kunye nokusetyenziswa kokupakisha  iimpompo zecala lokwahlula nge-axially .

Ngenxa yeemeko ezahlukeneyo zokusebenza, kukho iintlobo ezininzi zezinto zokupakisha. Ukuze ukwazi ukwahlula ngcono kunye nokukhetha ukupakisha, sihlala sohlula-hlula ukupakisha ngokwemathiriyeli yesiseko sokutywina esisisiseko sokupakisha:

1. Ukupakisha ifayibha yendalo. Ukupakishwa kwefiber yendalo kubandakanya ikakhulu umqhaphu wendalo, ilinen, uboya, njl.njl. njengezixhobo ezisisiseko sokutywina.

2. Ukupakisha i-mineral fiber. Ukupakishwa kwe-mineral fiber ikakhulu kubandakanya ukupakishwa kwe-asbestos, njl.

3. Ukupakishwa kwefayibha zokwenziwa. Ukupakishwa kwefayibha zokwenziwa ikakhulu kubandakanya: ukupakishwa kwegraphite, ukupakishwa kwefayibha yekhabhoni, ukupakishwa kwePTFE, ukupakishwa kweKevlar, ukupakisha kwe-acrylic-clip silicone fiber, njl.

4. Ukupakisha i-Ceramic kunye ne-metal fiber Ukupakisha i-Ceramic kunye ne-metal fiber ipakisha ikakhulu ibandakanya: ukupakisha i-silicon carbide, ukupakisha i-boron carbide, i-medium-alkali glass fiber packing, njl. ifayibha isetyenziselwa ukuluka ukupakisha. Ekubeni kukho izithuba phakathi kweefayili zokupakisha, kulula ukubangela ukuvuza. Kwangaxeshanye, ezinye iintsinga zineepropathi ezibuthathaka zokuzithambisa kunye ne-coefficient enkulu yokukhuhlana, ngoko ke kufuneka zifakwe kwezinye izinto zokuthambisa kunye nezihluzi. kunye nezongezelelo ezikhethekileyo, njl Ukuphucula ukuxinana kunye nokuthambisa kwe-filler, okufana ne-oyile yezimbiwa okanye i-molybdenum disulfide grease exutywe ne-graphite powder, i-talc powder, i-mica, i-glycerin, i-oyile yemifuno, njl. e Yongeza izixa ezifanelekileyo zee-surfactants kunye ne-dispersants kwi-emulsion. Izongezo ezikhethekileyo ngokuqhelekileyo ziquka iinqununu ze-zinc, i-barrier agents, i-molybdenum-based corrosion inhibitors, njl.
