Iimfuno zobugcisa ze-slurry impeller
Khangela i-shaft end face runout A kwinjongo yejenali kukuthintela ukuqokelela iimpazamo , xa ifakwe kwi-betting encinci ngokugqithisileyo, ichaphazela umgangatho wemveliso.Umlinganiselo obunye ubuso ngobuso obunxuseneyo nenqwelomoya yesalathiso, kodwa hayi elinye icala elijongene nejenali yokubaleka kobuso bokulinganisa, isizathu ngamanye amaxesha siyafuneka kwindlela yokulinganisa, ngamanye amaxesha ukuze kubonakaliswe ngcono umgangatho wokusetyenzwa.
Ukuphuma kunye nokuhambelana akukhuthazwa kwiThebhile 10-8 ukuphambuka kwemo kunye nesikhundla, ukhetho oluchanekileyo lwenqanaba.Umgca we-key ohamba nombindi we-skew ubhekiselele kumgca osembindini wendlela engundoqo kwi-engile ye-axis ye-shaft.I-Skew i-impeller kakhulu ayilayishwanga, ngakumbi indibano yempompo enezigaba ezininzi inzima kakhulu.
Ke ngoko, iimfuno ezingqongqo kwi-skew, ngokuqhelekileyo i-100 mm ubude be-keyway skew ukunyamezela 0.03 mm.I-keyway offset ihanjiswa ngaxeshanye nomgca we-axis .Impembelelo encinci kwindibano , ukunyamezela kukhulu, ukunyamezela ngokubanzi kwe-0.06 mm groove offset.Ukuze kugcinwe umngxuma ophakathi kungumngxuma ukwenzela ukuba kulungiswe isiseko se-centering.Uvavanyo lwe-Ultrasonic lwe-shaft kunye nenjongo yokufumanisa imagnethi kukukhangela ukuba kukho isiphene ngaphakathi kwe-shaft, i-shaft ukuqinisekisa ukuthembeka kokusebenza.I-Centrifugal pump impeller yeyona ndawo iphambili.
Ukusebenza kunye ne-impeller yoyilo lwempompo ye-centrifugal kunye nokuveliswa ( ukuphosa kunye nomatshini ) kunxulumene ngokusondeleyo nomgangatho.Imizobo yokwakhiwa kwe-impeller kunye neemfuno zobugcisa eziboniswe kwi-Figure 10-2,umenzi wempompo enodakaIimfuno zobuchwephesha be-impeller yokuqala, okwesibini, ezintathu iimfuno zobuchwepheshe kunye ne-shaft efanayo, jonga icandelo le-shaft.
Ukunyamezela ukukhutshwa okucetyiswayo kwiThebhile ye-10-7 imilo kunye nokuphambuka kwinqanaba le-VII lokukhetha ukuchaneka kwenqanaba, ukunyamezela ukugijima kobuso okucetyiswayo kwiThebhile 10-8 Icandelo le-VII lokuphambuka kwenqanaba lejometri ukukhetha ngokuchanekileyo.Nangona i-symmetrical shape ye-impeller , kodwa kwinkqubo yokuphosa kunye nempazamo yomatshini ihlala ikhona, enye yezizathu ze-centrifugal vibration zenzeka.Ngoko ke kufuneka ulungelelaniswe nge-statically impeller processed ukuphelisa ubunzima obungalinganiyo .
Unyamezelo oluqhelekileyo lwempompo ye-centrifugal ye-static ibhalansi ekhuthazwayo kwiThebhile ye-10-9 yokukhetha.Uvavanyo lwe-impeller static balance, ikhava yangaphambili kunye nendlela yokusika ukuphelisa ukungalingani, ubuninzi beplate yokusika abuyi kudlula i-1/3.Ukusuka ngaphambili , ipaneli yangasemva inqumle isinyithi esingaphezulu , kodwa indawo yokusika kufuneka idityaniswe ngediski egudileyo .Iimfuno zobugcisa ze-Impeller zesihlanu, zihlala zingahoywa ngokulula.Kwimveliso yemveliso ngenxa yesanti ngaphandle kwegill ayiphelelanga, kodwa ezichaphazela ukusebenza kwemveliso zizinto eziqhelekileyo, kodwa kwakhona ngovavanyo lwentsebenzo ikakhulu ukulungiswa, ukuchitha iiyure ezininzi, ngoko i-impeller kufuneka ibe yintlabathi ngononophelo ngaphandle kwegill.
