1. Incazelo yohlobo lwe-Graphite Packing
Kunezinhlobo ezi-3 ezilandelayo zokugcwalisa ezivame ukusetshenziswa kuzo ama-valve
Ukupakisha okusetshenziswe kule phrojekthi kuwuhlobo lokuvula okukodwa kuMfanekiso 1 kanye nokupakishwa okumise okwendandatho kuMfanekiso 3. Izithombe zangempela zimi kanje:
Umfanekiso 1 Ukupakisha kohlobo lokuvula okukodwa
Umfanekiso 3 Ukupakisha indandatho yokupakisha
Imisebenzi yokusetshenziswa yamaphakethe amabili angenhla iyafana, umehluko usezimweni ezihlukene zokusetshenziswa. Ukupakisha okuvula okukodwa kulungele ukufaka esikhundleni sokupakisha ngesikhathi sokulungiswa kwama-valve nsuku zonke. Ukupakisha kungashintshwa ku-inthanethi, futhi ukupakishwa kwendandatho yokupakisha kulungele ukulungisa i-valve. Isetshenziselwa ukuqaqa nokugcinwa.
2. Incazelo yezimpawu zokupakisha ze-graphite
Ngokusho kwezidingo zobuchwepheshe zokukhiqiza i-filler, isigcwalisi sidinga izinga elithile lokuqina, ngakho-ke kuyoba nokuqina okuvela ngaphakathi kuya ngaphandle ngemuva kokugcwaliswa kokwakhiwa. Izinhlobo ezimbili ezibalulwe ngenhla zokugcwalisa uhlobo olulodwa lokuvula ama-graphite zingamafayili alukiweyo inqubo yawo yokubumba iboshwe imicu eminingi ye-graphite, futhi ukuqina kudonswa igebe elilukiwe futhi awukho umkhondo osobala wokulangazelela ukwanda. Ukupakisha i-graphite yohlobo lwendandatho yokupakisha ukupakisha okuhlangene okungaphakathi okuhlangene. Ngemva kokuma isikhathi eside, ukuqina kwangaphakathi kuzobonisa imifantu ebusweni bokupakisha futhi kukhulule le ngxenye yokucindezeleka. Lolu hlobo lokugcwalisa luzohlala luzinzile futhi lungashintshi ngemva kokukhiqizwa kokuqhekeka okuthile. Uma kucindezela futhi, ukuqhekeka kuyanyamalala futhi izinga lokuphindaphinda lihlangabezana nemfuneko.
Okulandelayo yizimfuneko zobuchwepheshe zamasongo e-graphite aguquguqukayo

3. Mayelana nokusetshenziswa kwe-graphite ukupakisha
Ukupakishwa kwe-graphite kusetshenziswa endaweni evaliwe phakathi kwesiqu se-valve kanye ne-packing gland, futhi ukupakisha kusesimweni esicindezelwe ngesikhathi sokusebenza. Noma ngabe uhlobo oluvulayo lokupakisha olulodwa noma ukupakisha uhlobo lwendandatho yokupakisha, awukho umehluko emsebenzini wesimo esicindezelwe.
Okulandelayo umdwebo wesimo sokusebenza sokupakisha (umfanekiso wokuhlolwa kophawu lokupakisha)
