Mwachitsanzo, mankhwala asibesitosi akhoza kugwiritsidwa ntchito mu zipangizo njira mafuta, komanso amalankhulira ndi mankhwala. MwaukadauloZida yosindikiza ndondomeko imagwiridwa ndi njira makina wapadera.

Mankhwala ena anyamula akuimira mu kapangidwe ka ulusi graphite amene impregnated ndi PTFE ndi anatsindika njira ya ulusi thonje. packings oterowo ntchito kuti asindikize plunger ndipo mapampu centrifugal. Iwo bwino kupewa madzi kutayikira. Ndipo komabe anagonjera mankhwala amatha kulamulira mapampu kutentha, komanso kuchepetsa mowa awo mphamvu. chakuti ali ndi otsika koyefishienti wa kukhululukirana. Ubwino wa nkhani graphite ndi kuti iwo ndi kugonjetsedwa kwambiri kutentha (pafupifupi 550 madigiri ), Chemical kuukira. Komabe, n'zosatheka pansi anawerengazo chinyezi chifukwa angathandize kuti dzimbiri zitsulo mu zimagwirira.

Graphite packings ndi kudzikonda afewetsedwa. Gwiritsani ntchito mankhwala amenewa ayenera kuti asindikize malo upite pansi zimagwirira onse avundulidwe. yosindikiza ndondomeko kawirikawiri chofunika zofunikira pa breakage a mipope madzi kapena machitidwe magetsi. Ndiyamika relievers zotheka osati kuletsa kutayikira, komanso kuteteza pakuwonekera kwake zina.

Ngati inu ntchito stuffing bokosi atanyamula kuti mapampu centrifugal, ndi bwino kusankha thonje chingwe. Pre-mankhwala ayenera ankawaviika yamphamvu mafuta, imene padzakhala pang'ono phula. Ubwino wa nkhaniyi ndi kuti mukhoza kupirira mavuto 20 MPa ndipo amagwira ntchito yake bwino pa lonse kutentha osiyanasiyana (kwa madigiri -40 kuti +100). Komabe, mankhwala mwamsanga anawononga mchikakamizo cha alkalis ndi zidulo.
