Wear design factors slurry pump manufacturer 's He nui nā kumu hoʻolālā lole slurry pump manufacturer, a ʻaʻole like nā ʻāpana like ʻole a me nā ʻāpana like ʻole o nā mīkini, akā ma ka laulā hiki ke hōʻuluʻulu ʻia i ʻekolu mau ʻāpana:
1 Erosion: I loko o ka mea hana slurry pump i ka wā e hana ai, lawe ʻia ka wai i nā ʻāpana paʻa i kahi kahe kahe ma luna o ka ʻili o ka lālā hopena, e hopena i ka poho waiwai.E like me ka nānā ʻana o ka hemahema o ka ʻaʻahu o ka ʻāpana erosion mechanical hiki ke hoʻokaʻawale ʻia i ka ʻoki ʻana i ka lole a me ka deformation lole a me ka luhi luhi o ka ʻoki + composite deformation.
2 ka pōʻino cavitation: I ka wā o ka hana ʻana o ka paila, nā ʻāpana kahe e pili ana i ka ʻāina kūloko (maʻamau ma ka impeller inlet ma hope aku), no kekahi kumu, hoʻoheheʻe ʻia ka wai i ka manawa e hāʻule ai ke kaomi piha i ke kaomi mahu o ka mahana, kahi. hoʻomaka ka wai e hoʻohua i ka mahu , ka hoʻokumu ʻana o nā ʻōpū .Ke kahe nei kēia mau ʻōhū me ka wai i mua, a hiki i ka piʻi kiʻekiʻe, hāʻule nā ʻōhū me ka hoʻemi nui ʻia.I kēia manawa i ka condensation bubble, nā ʻāpana wai i ka wikiwiki e hoʻopiha ana i nā lua, a he hopena ikaika i ka ʻili metala.ʻO kēia ʻili metala ke ʻokiʻoki ma muli o ka hopena o ka luhi, ka hopena i ka poho waiwai, ʻili metala koʻikoʻi e hōʻike ana i ka honeycomb.Loaʻa nā ʻāpana o ka cavitation ma ka puka impeller a me ka puka komo volute.
3 ʻaʻahu corrosive: Ke loaʻa kahi pH i ka medium transmission,mea hana pahū slurryʻO nā ʻāpana kahe e hiki mai ke ʻaʻahu ʻino , ʻo ia hoʻi ka nalowale ʻana o nā mea kūlohelohe ma lalo o ka hana hui ʻana o ka ʻino a me ke kapa.
Hiki ke hoʻokaʻawale ʻia ka corrosion i ka corrosion kemika a me ka corrosion electrochemical.ʻO ka corrosion kemika o ka metala a me ka wai wai pane pololei me ka waiho ʻana i ka nalowale metala, ʻo ka ʻino electrochemical i loko o ka wai wai ka hana o ka ʻili metala e hana i ka micro-batri e waiho ana i ka poho waiwai.Ma muli o ka hoʻohana maoli ʻana o ka mea metala he mau mea polycrystalline multiphase, no laila, he corrosion mua, electrochemical corrosion, ʻoi aku ka ʻino o ka palena aniani, ua hoʻokumu ʻia nā māwae intergranular i nā mea metala, a e hoʻokaʻawale i nā ʻāpana paʻakikī a i ʻole, nalowale ke kākoʻo, no laila e hele mai ia. i loko o ka erosion i puka mai nā ʻāpana paʻa;ʻoiai e ʻimi ana i nā ʻāpana paʻa, a me ka ʻili o ka metala ma muli o ka papa passivation e hoʻoheheʻe ʻia e hana i ka wai wai e pili ana me ka ʻili metala e hoʻonui ai i ka corrosion hou.Ua ʻike ʻia he corrosion ka mea hana pahū slurry i ka nānā ʻole ʻana i ke ʻano o ke ʻano.
