Lub phaj clutch yog ib hom khoom sib xyaw ua ke uas muaj kev sib txhuam ua lub luag haujlwm tseem ceeb thiab kev ua haujlwm ntawm cov qauv. Cov khoom siv sib txhuam hauv tsheb feem ntau yog siv rau hauv kev tsim cov phaj sib txhuam nres thiab cov phaj clutch. Cov khoom siv sib txhuam no feem ntau siv cov khoom siv sib txhuam asbestos, nrog rau qhov xav tau siab dua rau kev tiv thaiv ib puag ncig thiab kev nyab xeeb, maj mam tshwm sim cov khoom siv sib txhuam semi-metallic, cov khoom siv sib txhuam fiber sib xyaw, cov khoom siv sib txhuam ceramic fiber.
Vim tias cov khoom siv sib txhuam feem ntau yog siv rau hauv kev tsim cov khoom nres thiab cov khoom sib kis, nws xav tau cov coefficient sib txhuam siab thiab ruaj khov thiab tiv taus kev hnav zoo.
Lub clutch yog ib hom mechanism uas xa lub zog los ntawm axial compression thiab tso tawm nrog kev pab los ntawm ob lub clutch friction plates uas tiaj tiaj. Qhov siab axial ntawm ob lub clutch plates ntau dua, qhov kev sib txhuam ntau dua, thiab qhov ruaj khov thiab ib txwm ua haujlwm ntawm lub extruder raug xa mus. Hauv kev ua haujlwm ib txwm, lub tshuab feem ntau qhia kev ua haujlwm ruaj khov thiab tsis muaj suab nrov; Nyob rau hauv qhov hnyav ntsuas, lub clutch disc yuav tsis plam, yuav tsis daig, yuav tsis tawm; Tib lub sijhawm, tom qab lub clutch plate raug cais, nws kuj yuav tsum tau cais ntawm lub tshuab cib kom tsis txhob khiav tag nrho, tsis muaj lwm yam suab nrov lossis ob lub clutch plates tsis sib cais tag nrho thiab lwm yam. Yog li ntawd, nws yog qhov tsim nyog los kho lub clutch hauv qhov sib txawv, qhov sib txawv yuav ua rau lub clutch disc plam, ua rau lub clutch disc puas tsuaj, qhov sib txawv yuav ua rau lub clutch disc tsis yooj yim cais thiab lwm yam.
