Amaphampu ane-slurry asetshenziswa kakhulu, futhi imidiya edluliswayo iya ngokuya iba yinkimbinkimbi.Nakuba kudingeka ukuthi sehlise ukuguga kwephampu ye-slurry, futhi sinezidingo eziqinile zokuvala uphawu lwephampu enodaka.Uma ukusebenza kokuvala kungalungile, imidiya eminingi izovuza., okuholela ekulahlekelweni okungadingekile.
Ngakho-ke, ukubeka uphawu kuyinto ehamba phambili.Nazi izinhlobo ezintathu zefomu lokuvala amaphampu anodaka: Packing seal, Expeller seal, kanye neMechanical seal.
Ukupakisha uphawu
Indlela ejwayeleke kakhulu yokuvala iwukuba ujove ngokuqhubekayo amanzi okucindezela okuthile endaweni yokupakisha ngokujova amanzi okuvalwa kwe-shaft ukuvimbela umzimba wepompo ukuthi ungaphumi.Kumaphampu e-tandem anezigaba eziningi angafanelekile ukusetshenziswa nama-expeller seals, kusetshenziswa izimpawu zokupakisha.
I-slurry pump packing seal inesakhiwo esilula, ukulungiswa okulula kanye nentengo ephansi.
Exi-peller seal
I-slurry ivinjelwa ukuthi ingavuzi ngokusebenzisa i-reverse centrifugal force yomxoshi.Uma inani lokucindezela elihle le-pump inlet lingekho ngaphezu kuka-10% yenani lokucindezela kokuphuma kwepompo, iphampu yesigaba sokuqala sepompo yesiteji esisodwa noma iphampu yochungechunge lwezigaba eziningi ingasebenzisa uphawu lokuxosha.I-auxiliary expeller seal inezinzuzo zokungadingi amanzi e-shaft seal, akukho ukuhlanjululwa kwe-slurry, nomphumela omuhle wokuvala.
Ngakho-ke lolu hlobo lokuvala lungacatshangelwa lapho ukuhlanjululwa kungavunyelwe odongeni.
Muphawu lwe-echanical
Izigxivizo zemishini zisetshenziswa lapho izidingo zokuvala ziphezulu uma kuqhathaniswa.Ikakhulukazi kwezinye izinkambu zamakhemikhali nokudla, akugcini nje ukubekwa uphawu, kodwa futhi imidiya eyengeziwe ayivunyelwe ukungena emzimbeni wepompo.
Ukungalungi kwesigxivizo semishini yepompo ye-slurry ukuthi izindleko ziphezulu futhi ukugcinwa kunzima.
