Centrifugal pombi yakavhurika impeller yesimbi isina tsvina nekukanda mari,CNC machininguye dynamic balancing.
Matanho e Investment Casting process:
Munguva yekudyara kwekudyara maitiro, wax pateni inoputirwa neceramic material, iyo, kana yakaomeswa, inotora iyo yemukati geometry yekukanda yaunoda. Kazhinji, zvikamu zvakawanda zvinokandwa pamwechete kuti zvinyatsoshanda nekuisa mapatani ewakisi ega pachimuti chepakati chinonzi sprue. Wakisi inonyungudutswa kubva patani - ndokusaka ichizivikanwawo senzira yakarasika wakisi - uye simbi yakanyungudutswa inodirwa mugomba. Kana simbi yasimba, mold yeceramic inozununguswa, ichisiya chimiro chiri padyo chekukandwa kwaunoda, kuchiteverwa nekupedzisa, kuyedza uye kurongedza.
CF8M ndeye cast austenitic simbi isina tsvina iyo yakafukidzwa neASTM A351, ASTM A743 uye ASTM A744 yakajairwa. CF8M yakaenzana neSS 316/F 316 uye Chinese Standard 0Cr17Ni12Mo2. CF8M imolybdenum inobereka gadziriso yeCF8 alloy uye ndiyo yakakandwa yakaenzana neyakagadzirwa AISI 316 Stainless simbi. Kuvapo kwe molybdenum kunowedzera kusimba kwekuora uye kuramba kwegomba nemakloridi. Iyo alloy inoshandiswa mune zvinyoro acidic uye alkaline mamiriro uye kubata citric, oxalic uye phosphoric acids. Stainless simbi CF8M inonyanya kufanana SS 316, F 316 uye TP 316. Asi ivo vanotsanangurwa mumiyero yakasiyana, uye makemikari avo uye michina zvinhu zvakasiyana zvishoma zvakare. CF8M inotsanangurwa muASMT A351, ASMT A743 uye ASTM A744, inova yekukanda chinangwa chete. SS 316 inotsanangurwa muASTM A240 uye ASTM A276, ndeye ndiro, shizha, mitsetse kana simbi isina tsvina. Rimwe giredhi rakadanwa seF316, rinobva kuASTM A182 yezvikamu zvefoge chete. TP316 ichawanikwa muATSTM A376 yepombi chete. Iwo mashandisirwo makuru eCF8M akakanda simbi isina chivharo chivharo: impellors, propeller, pombi casings, miviri yevharuvhu uye mahwendefa ekudhinda. Iyo yakajairika kupisa kurapwa kweCF8M yakasimba Solution nekudziisa kune inodarika 1900 °F (1040 °C), ichibata kwenguva yakakwana uye ipapo kudzima mumvura kana kukurumidza kutonhora nedzimwe nzira.
