Iingqwalaselo zokuKhetha impompo ye-FGD



I-Flue gas desulfurization (FGD) yinkqubo apho ukukhupha iirhasi ezivela kwizityalo zamandla ezibaselwe ngefosili zinokukhutshelwa ngokukhuselekileyo emoyeni. I-FGD slurries idla ngokurhawuzelela, idlavuza kwaye ixinene. Ukumpompa i-slurries ezonakalisayo ngokuthembekileyo, impompo kufuneka yenzelwe ngokukodwa ukusebenza kakuhle, okupholileyo. Kufuneka yenziwe kwizinto ezilungele i-slurry ethile, ihlanganiswe ngokuchanekileyo kwaye ifakwe ngokufanelekileyo.

 

Uthotho lwe TL >impompo yeFGD yimpompo ye-centrifugal yenqanaba elinye. Isetyenziswa ikakhulu njengempompo yokujikeleza kwinqaba efunxayo kwizicelo zeFGD. Ineempawu ezinjalo: umthamo obanzi wokuqukuqela, ukusebenza kakuhle okuphezulu, ukonga amandla aphezulu. Olu luhlu lwempompo luhambelana nesakhiwo esiqinileyo X isibiyeli esinokugcina indawo eninzi. Ngeli xesha inkampani yethu iphuhlisa iintlobo ezininzi zezinto ezijoliswe kwiimpompo ze-FGD.

 

Ukufezekisa ixabiso elingcono

Ukunqanda ixesha lokuphumla elingacwangciswanga, iindawo ezibuthathaka kufuneka ziqondwe kwaye ziqwalaselwe. Iindawo ekufuneka ziqwalaselwe kwi-slurries ezonakalisayo zibandakanya izitywini zeshaft, ii-cable inlets kunye nokupholisa.

Impompo ye-TL FGD

Ngamanani

No. 1, i-silicon carbide mechanical seal face iyadingeka. Uvavanyo lubonise ukuba i-silicon carbide shaft seals ngamaxesha angama-15-20 ahlala ixesha elide kunekhabhoni ye-ceramic kunye namaxesha angama-2.5-3 ahlala ixesha elide kune-tungsten carbide. Ubuso bokutywina kufuneka bube tyaba - (ixesha elithile, kodwa elithambileyo lingcono) - ukungabandakanyi amaqhekeza amancinci; intwasahlobo ebonelela ngoxinzelelo lokuvala obu buso kufuneka ibe yodwa eludaka.

 

Inqaku lesi-2, isango lokungena kwekhebula kufuneka litywinwe kwigumbi lemoto ukuze kugcinwe ingqibelelo yemoto kwimeko yokungena komswakama ukusuka phezulu, kwaye kufuneka kubonelele ngesixhobo esihle sokunciphisa uxinzelelo. Abaqhubi ngabanye bahluthwa kwi-wire engenanto kwaye badlule kwisithintelo se-epoxy ukukhusela umswakama kwikhebula eyonakalisiweyo ekungeneni kwigumbi le-stator. Ibhlokhi yokugcina yodwa ibonelela ngokhuseleko olongezelelweyo kwaye i-O-ring itywinwe. Le bhodi ingasetyenziselwa ukuququzelela ukuguquguquka kwamandla ombane.

 

Inombolo ye-3, ngokubanzi, ubushushu bunokugqithiswa ngendlu yemoto ukuya kwindawo yokupompa. Indlela eqhubeka nokuchitha ubushushu bejenereyitha ngokutshintsha ubushushu kufuneka isetyenziswe - nangona igypsum okanye ezinye izinto zinokubangela ukugquma kobushushu. Indlela yokupholisa kufuneka iqhutywe 24/7 kumthwalo ogcweleyo.

 

Iindlela zokupholisa zangaphakathi ezinobundlobongela zivumela ukumpompa ukuya kwinqanaba elisezantsi lamanzi kwi-sump, ngaloo ndlela ukwandisa umthamo we-sump; oku kungatolika kumakhulu eegaloni zomthamo we-sump.

 

Inqaku lesi-4, isambatho esikhuselayo sidinga iimpawu eziphezulu zokubambelela ngenxa yesenzo se-hydraulic kwi-sump. Iingubo zokunamathela eziphantsi zinokungaphumeleli kwangaphambi kwexesha. (Ukuncamathela kulinganiswa ngeeNewtons nge-square millimeter nganye (N/mm2).) Umzekelo, iipeyinti zepeyinti eziqhelekileyo zemizi-mveliso zinenqanaba lokuncamathela elimalunga ne-4 N/mm2, lo gama iikhomponenti ezimbini ezinepesenti ephezulu yezinto eziqinileyo zinenqanaba lokuncamathela. malunga ne-7 N/mm2. Namhlanje, iingubo ze-ceramic zamanzi zine-adhesion ye-15 N / mm2. Iingoma ze-elastomeric zixhathisa ukubola kunye neekeramics ezifakwe ngaphakathi zixhathisa ukunxiba.

 

Inombolo ye-5, i-high-chrome impahla eqinile (ukuya kwi-650 kunye ne-BHN; i-Rockwell “C” Isikali se-63) kufuneka sinikezelwe xa i-abrasion ingumba ophambili. Kwiimeko apho ukudleka kuyinkxalabo enkulu, kufuneka kusetyenziswe ii-Duplex Stainless Steels ezifana ne-CD4MCU.
