Chitsanzo cha kugwiritsa ntchito graphite yowonjezereka

Kugwiritsa ntchito chodzaza cha graphite chokulirapo ndi zinthu zotsekera ndikothandiza kwambiri m'zitsanzo, makamaka zoyenera kutsekera pansi pa kutentha kwambiri komanso kupanikizika komanso kutsekera kudzera mu zinthu zoopsa komanso zowononga. Ubwino waukadaulo komanso zotsatira zake zachuma ndizodziwikiratu. Mkonzi wotsatira wa graphite wa Furuite akukupatsani:

Kupaka graphite yowonjezera kungagwiritsidwe ntchito pa ma valve amitundu yonse ndi zisindikizo za pamwamba pa makina akuluakulu a nthunzi a 100,000 kW omwe ali mu thermal power plant. Kutentha kwa nthunzi ndi 530℃, ndipo palibe vuto lotayikira pambuyo pa chaka chimodzi chogwiritsidwa ntchito, ndipo tsinde la valavu ndi losinthasintha komanso lopulumutsa ntchito. Poyerekeza ndi asbestos filler, nthawi yake yogwirira ntchito imawirikiza kawiri, nthawi yokonza imachepetsedwa, ndipo ntchito ndi zipangizo zimasungidwa. Kupaka graphite yowonjezera kumayikidwa pa payipi yonyamula nthunzi, helium, hydrogen, petulo, gasi, mafuta a sera, kerosene, mafuta osakonzedwa ndi mafuta olemera mu fakitale yamafuta, yokhala ndi ma valve 370, onse omwe ndi opakidwa graphite yowonjezera. Kutentha kwa ntchito ndi madigiri 600, ndipo ingagwiritsidwe ntchito kwa nthawi yayitali popanda kutuluka.
Zikumveka kuti chodzaza cha graphite chowonjezera chagwiritsidwanso ntchito mu fakitale yopaka utoto, komwe kumapeto kwa shaft ya ketulo yopangira varnish ya alkyd kumatsekedwa. Chogwirira ntchito ndi dimethyl nthunzi, kutentha kogwira ntchito ndi madigiri 240, ndipo liwiro la shaft yogwira ntchito ndi 90r/min. Chagwiritsidwa ntchito kwa zaka zoposa chimodzi popanda kutuluka, ndipo zotsatira zake zimakhala zabwino kwambiri. Chodzaza cha asbestos chikagwiritsidwa ntchito, chiyenera kusinthidwa nthawi iliyonse mwezi uliwonse. Mukagwiritsa ntchito chodzaza cha graphite chowonjezera, chimasunga nthawi, ntchito ndi zipangizo.
