I-HGL/HGW uchungechunge lwenqanaba elinye iimpompo zekhemikhali ezithe nkqo nezithe tyaba

Isicelo

I-HGL kunye ne-HGW iimpompo zeekhemikhali zechungechungeingasetyenziselwa kwinqanaba elithile kwishishini lemichiza, ukuthuthwa kweoyile, ukutya, isiselo, amayeza, unyango lwamanzi, ukukhuselwa kwendalo kunye nezinye iiasidi, i-alkali, ityuwa kunye nezinye izicelo ngokwemiqathango ethile yokusetyenziswa komsebenzisi.I-medium e-corrosive, ayinamasuntswana aqinileyo okanye inani elincinci lamasuntswana, kwaye ine-viscosity efana namanzi.Ayikhuthazwa ukuba isetyenziswe kwiimeko eziyityhefu, ezinokutsha, eziqhumayo, okanye ezinoburharha obuphezulu.

(1) I-asidi ye-nitric kunye nokusetyenziswa kwishishini le-nitric acid

Kwinkqubo yokuvelisa i-nitric acid nge-ammonia oxidation, i-dilute nitric acid (50-60%) eyenziwa kwinqaba yokufunxa insimbi engenasici iphuma ezantsi kwenqaba ukuya kwitanki yokugcina intsimbi, kwaye ithuthelwa kwinkqubo elandelayo. ngempompo yentsimbi engenasici.Nika ingqalelo kubushushu obuphakathi kunye noxinzelelo lokungena apha.

(2) Izicelo kwi-phosphoric acid kunye ne-phosphoric acid industry

Kwiasidi esulungekileyo, intsimbi ye-Cr13 engenasici ixhathisa kuphela kwi-aerated dilute acid, kunye ne-chromium-nickel (Cr19Ni10) i-austenitic stainless steel ixhathisa kuphela kwi-aerated dilute acid.Eyona nto i-phosphoric acid-resistant-resistant yi-chromium-nickel-molybdenum (ZG07Cr19Ni11Mo2) insimbi engenasici, njl.

Nangona kunjalo, kwinkqubo yokuvelisa i-asidi ye-phosphoric, ukukhethwa kwezinto zempompo kunzima kakhulu ngenxa yeengxaki ze-corrosion ezibangelwa ubukho bokungcola kwi-asidi ye-phosphoric, kwaye kufuneka iphathwe ngononophelo.

(3) Ukusetyenziswa kwi-sodium chloride kunye noshishino lwetyuwa (amanzi ane-brine, amanzi olwandle, njl.)

I-Chromium-nickel steel stainless steel inezinga eliphantsi kakhulu le-corrosion ye-uniform ngokuchasene nokungathathi hlangothi kunye nezisombululo ze-alkaline ye-sodium chloride, amanzi olwandle kunye namanzi etyuwa kubushushu obuthile kunye noxinzelelo, kwaye isetyenziswa ngokubanzi.Nangona kunjalo, kufuneka kuqatshelwe ukuba i-corrosion yendawo enobungozi ingenzeka kwezinye iimeko.

Iimpompo zentsimbi engenasicizisetyenziswa kakhulu kwishishini lokutya lokuphatha i-brine kunye nokutya okunetyuwa.Nangona kunjalo, ingqalelo kufuneka ihlawulwe kwimiba ye-crystallization yemidiya kunye nemiba yokukhetha uphawu lomatshini.

(4) Ukusetyenziswa kwi-sodium hydroxide kunye ne-alkali industry

I-Chromium-nickel i-austenitic steel stainless inokumelana ne-sodium hydroxide engaphantsi kwe-40-50% ukuya malunga ne-80 ° C, kodwa ayichasananga ne-high-concentration kunye ne-high-temperature alkali liquid.

I-Chromium insimbi engenasici ifanelekile kuphela kwiqondo lokushisa eliphantsi kunye nezisombululo ze-alkali eziphantsi.

Ingqalelo kufuneka ihlawulwe kwingxaki ye-crystallization ephakathi.

(5) Isicelo ekuthuthweni kweoli

Ingqalelo kufuneka ihlawulwe kwi-viscosity ye-medium, ukukhethwa kweendawo zerabha, kunye nokuba i-motor ineemfuno zobungqina bokuqhuma, njl.

(6) Ukusetyenziswa kwishishini lamayeza

Iimpompo zonyango zinokwahlulwa zibe zezi ndidi zimbini zilandelayo ngokwendlela yokuhanjiswa kwempompo:

Olunye uhlobo ziimpompo zamanzi eziqhelekileyo, iimpompo zamanzi ashushu kunye neempompo zenkqubo yokucoca amanzi amdaka asetyenziswa kwiiprojekthi zikawonke-wonke, kwaye olunye uhlobo ziimpompo zokuhambisa inkqubo yemidiya efana nolwelo lwekhemikhali, i-intermediates, amanzi acocekileyo, iiasidi kunye nealkali.

Eyangaphambili ineemfuno ezisezantsi zeempompo kwaye inokuphathwa ngeempompo ezisetyenziselwa izixhobo zeekhemikhali eziqhelekileyo, ngelixa le yokugqibela ineemfuno eziphezulu kwiimpompo.Iimpompo kufuneka zihlangabezane neemfuno zobugcisa kwiimpompo ze-centrifugal ezisetyenziswa kwizixhobo zonyango.

(7) Ukusetyenziswa kwishishini lokutya kunye nesiselo

Kwishishini lokutya kunye nesiselo, i-medium ayinayo i-corrosion okanye i-corrosive ebuthakathaka, kodwa i-rust ayivunyelwanga, kwaye ukucoceka kwe-medium kuphezulu kakhulu.Kule meko, impompo yensimbi engenasici ingasetyenziswa.

Iimpawu zesakhiwo

1. Uyilo olucandiweyo lwe-shaft yempompo yolu luhlu lweempompo luthintela ngokusisiseko ukonakala kwe-motor shaft.Oku kuqinisekisa ngokupheleleyo ukusebenza okuzinzileyo nokuthembekileyo kwexesha elide lemoto.

2. Olu chungechunge lweempompo lunokwethenjelwa kunye neveli yesakhiwo se-shaft pump.Impompo ethe nkqo inokusebenzisa ngokulula i-B5 yesakhiwo semoto esemgangathweni ukuqhuba ngokuthe ngqo impompo yamanzi, kwaye impompo ethe tye inokusebenzisa ngokulula i-B35 yesakhiwo semotor esemgangathweni ukuqhuba ngokuthe ngqo impompo yamanzi.
