Theslurry pombiipombi inotakura musanganiswa wezvakaoma nemvura. Nokudaro, iyo yepakati inenge iine abrasive kune inoyerera zvikamu zve slurry pump. Naizvozvo, iyo slurry pombi inoyerera zvikamu zvinoda kugadzirwa nezvinhu zvinopfekwa.
Iyo inowanzoshandiswa simbi zvinhu zvemapombi eslurry zvakakamurwa kuita simbi yakakandwa, ductile iron, yakakwirira chromium cast iron, Stainless simbi, zvichingodaro. Yakakwira chromium cast iron ndiyo chizvarwa chechitatu chekupfeka-inodzivirira zvinhu zvakagadzirwa mushure meyakajairwa chena simbi yakakandwa uye nickel yakaoma simbi yakakandwa. Nekuda kwehunhu hwechimiro cheyakakwirira chromium simbi yakakandwa, ine yakanyanya kusimba, yakakwirira tembiricha simba, kupisa kupisa, uye kupfeka kuramba kupfuura yakajairwa simbi yakakandwa. High chromium cast iron yakarumbidzwa seyakanakisa anti-abrasive zvinhu munguva yemazuva ano, uye yakashandiswa zvakanyanya zuva nezuva.
Chiyero chenyika cheChina chekupfeka-inodzivirira simbi chena yakakandwa (GB/T8263) inotaura giredhi, kuumbwa, kuoma, maitiro ekupisa kupisa, uye mashandisirwo emhando yepamusoro chromium chena yakakanda iron.
Iyo yepamusoro chiyero cheyakakwira chromium cast iron muUnited States ndeye ASTMA532M, United Kingdom BS4844, Germany DIN1695, uye France NFA32401. Russia yakagadzira 12-15% Cr, 3-5.5% Mn uye 200mm mudhuri makobvu ebhora rezvigayo mune yaimbova Soviet Union, uye ikozvino inoshandisa iyo ҐOCT7769 standard.
Zvishandiso zvikuru zvinoshandiswa kune zvinoyerera zvikamu zvemapombi e slurry kumba nekune dzimwe nyika isimbi isina tsvina, yakakwira chromium cast iron, uye nickel hard cast iron. Yakakwira chromium cast iron ndiyo yakanakira mumiriri zvinhu zvezvinoyerera zvikamu zve slurry pombi. Kuburikidza nekugadzirisa kana kusarudzwa kwekabhoni uye chromium yemukati mazinga, iyo yakanyanya kunaka mhedzisiro yezvikamu zvinoyerera pasi pemamiriro akasiyana eindasitiri nemigodhi anogona kuwanikwa.
Yakakwira chromium cast iron ndiko kupfupikiswa kweyakakwira chromium chena anti-wear cast iron. Iyo inopesana-kupfeka zvinhu nekuita kwakanakisa uye kutarisisa kwakakosha; ine yakakwira kupfeka kuramba kupfuura alloy simbi uye yakanyanya kusimba uye kusimba kupfuura simbi chena yakakandwa. Panguva imwecheteyo, inewo kumira zvakanaka kune tembiricha yepamusoro uye ngura, yakasanganiswa nekugadzirwa kuri nyore uye mutengo uri pakati nepakati, uye inozivikanwa seimwe yeakanakisa anti-abrasive zvinhu munguva dzazvino.
Iye zvino Nhepfenyuro yeyakakwira chromium cast iron inodzivirira zvinhu inowanzoshandiswa:
Iyo slurry pombi yakagadzirwa neA05 (Cr26) zvinhu ndiyo inonyanya kushandiswa muindasitiri yemigodhi. Iyo microstructure yeyakakwira chromium alloy A05 inoratidza kuti ine yakaoma eutectic chromium carbides mune yakaomeswa yakazara marten-saiti matrix. Mune slurry pombi maapplication uko ese ari abrasive uye ari corrosive asi abrasion inotonga, kuita kwechinhu ichi kuri nani zvakanyanya kupfuura mamwe machena akakanda iron.
Kunyange zvazvo zvikamu zvakanyoroveswa zvakagadzirwa neA07 (Cr15Mo3) zvinhu zvine kukwirira kupfeka kusagadzikana, kuoma kuri nani, uye hupenyu hurefu hwebasa kupfuura A05, mari yavo inopeta kaviri yeA05, saka mutengo wekuita wakaderera uye chiyero chekushandisa idiki.
A49 (Cr30) inonyanya kukwirira chromium yakaderera kabhoni chena yakakandwa simbi. Iyo microstructure ndeye hypoeutectic uye ine eutectic chromium carbides mune austenite / martensite matrix. Iyo kabhoni yemukati yeyakakwira chromium A49 yakaderera pane iyo yepamusoro chromium A05. Kune yakawanda chromium mumatrix. Munzvimbo ine acidic isina kusimba, yakakwira chromium A49 ine yakakwira corrosion resistance pane yakakwira chromium A05.
Parizvino, zvakataurwa pamusoro apa zvinhu zvesimbi zvinowanzoshandiswa muslurry pombi mutengesi. Zvinoenderana nehunyanzvi hwepakati inotakurwa, isu tichasarudza iyo yakanyanya kufanira zvinhu.
