1. I-NPSHA engaqondakaliyo

Eyona nto ibalulekileyo yi-NPSHA yepompo yokufunxa kabini. Ukuba umsebenzisi akayiqondi ngokuchanekileyo i-NPSHA, ipompo iya ku-cavitate, ibangele umonakalo obiza kakhulu kunye nexesha lokuphumla.

2. Indawo esebenza ngokugqwesileyo

Ukubaleka impompo kude neNdawo yokuSebenza ngokuFanelekileyo (BEP) yingxaki yesibini eqhelekileyo echaphazela iimpompo zokufunxa kabini. Kwizicelo ezininzi, akukho nto inokwenziwa malunga nemeko ngenxa yeemeko ezingaphaya kolawulo lomnini. Kodwa kuhlala kukho umntu, okanye ixesha lilungile, ukucinga ngokutshintsha into ethile kwinkqubo ukuvumela impompo ye-centrifugal ukuba isebenze kwindawo eyenzelwe ukusebenza kuyo. Iinketho eziluncedo ziquka ukusebenza kwesantya esiguquguqukayo, ukulungelelanisa i-impeller, ukufaka ipompo yobungakanani obuhlukeneyo okanye imodeli yempompo eyahlukileyo, kunye nokunye.

3. Uxinzelelo lwemibhobho: I-Silent Pump Killer

Kubonakala ngathi i-ductwork kaninzi ayilungiswanga, ifakwe okanye ifakwe i-ankile ngokuchanekileyo, kwaye ukwandiswa kwe-thermal kunye nokunciphisa akuqwalaselwa. Uxinzelelo lwemibhobho ngoyena nobangela ukrokrelayo wokuzala kunye neengxaki zetywina. Umzekelo: emva kokuba siyalele injineli ekwisiza ukuba isuse iibholithi zesiseko sempompo, impompo ye-1.5-toni iye yanyuswa ngumbhobho ngamashumi eemilimitha, ngumzekelo woxinzelelo olukhulu lwemibhobho.

Enye indlela yokukhangela kukubeka isalathisi sokudayela ekudibaniseni kwiiplani ezithe tye kunye nezithe nkqo kwaye emva koko ukhulule umbhobho wokufunxa okanye wokukhupha. Ukuba isalathisi sokudayela sibonisa ukunyakaza okungaphezulu kwe-0.05 mm, umbhobho unzima kakhulu. Phinda la manyathelo angasentla kwelinye iflange.

4. Qalisa Ukulungiselela

Iimpompo zokufunxa kabini zazo naziphi na isayizi, ngaphandle kwamandla asezantsi ehashe adityanisiweyo adityanisiweyo, iiyunithi zempompo ezinyuswe ukutyibilika, azifane zifike zilungele ukuqala kwindawo yokugqibela. Ipompo ayikho "iplagi kunye nokudlala" kwaye umsebenzisi wokugqibela kufuneka afake ioli kwizindlu zokuthwala, usethe i-rotor kunye ne-impeller clearance, usethe isitywina somatshini, kwaye wenze isheke lokujikeleza kwi-drive ngaphambi kokufaka ukudibanisa.

5. Ulungelelwaniso

Ukulungelelaniswa kokuqhuba kwimpompo kubalulekile. Kungakhathaliseki ukuba ipompo ihambelana njani nefektri yomenzi, ukulungelelaniswa kunokulahleka ngexesha lokuthunyelwa kwempompo. Ukuba ipompo igxile kwindawo efakwe kuyo, inokulahleka xa idibanisa iipayipi.

6. Inqanaba leoli kunye nokucoceka

Ioli eninzi idla ngokuba ngcono. Kwiibheringi zebhola ezinezixokelelwano zokuthambisa i-splash, elona nqanaba le-oyile lifanelekileyo kuxa i-oyile idibana nomzantsi webhola esezantsi. Ukongeza ioli eninzi kuya kwandisa ukukhuhla kunye nobushushu. Khumbula oku: Owona nobangela mkhulu wokusilela kokuthwala kungcoliseko lwe-lubricant.

7. Ukusebenza kweMpompo eyomileyo

Ukuntywiliselwa (untywiliselo olula) kuchazwa njengomgama olinganiswa ngokuthe nkqo ukusuka kumphezulu wolwelo ukuya kumgca osembindini wezibuko lokufunxa. Okubaluleke ngakumbi kukuntywilisela okuyimfuneko, okwakwaziwa njengobuncinane okanye ukuntywiliselwa okubalulekileyo (SC).

I-SC ngumgama othe nkqo ukusuka kumphezulu wolwelo ukuya kwindawo yempompo yokufunxa kabini efunekayo ukunqanda ulwelo lwesiphithiphithi kunye nokujikeleza kolwelo. I-turbulence inokwazisa umoya ongafunekiyo kunye nezinye iigesi, ezinokubangela umonakalo wepompo kunye nokunciphisa ukusebenza kwempompo. Iimpompo ze-Centrifugal azikho i-compressors kwaye ukusebenza kunokuchaphazeleka kakhulu xa upompa i-biphasic kunye / okanye i-multiphase fluids (igesi kunye ne-air intrainment in the fluid).

8. Qonda uxinzelelo lweVacuum

Ivacuum sisifundo esibangela ukubhideka. Xa ubala i-NPSHA, ukuqonda kakuhle isihloko kubaluleke kakhulu. Khumbula, nakwi-vacuum, kukho umlinganiselo othile woxinzelelo (olupheleleyo) - nokuba luncinci kangakanani na. Ayiloxinzelelo olupheleleyo lwe-atmospheri oqhele ukwazi ukusebenza kwinqanaba lolwandle.

Ngokomzekelo, ngexesha lokubala kwe-NPSHA ebandakanya i-condenser yomphunga, unokuhlangabezana ne-vacuum ye-28.42 intshi ye-mercury. Nokuba kukho ivacuum ephezulu, kusekho uxinzelelo olupheleleyo lwe-intshi ye-1.5 ye-mercury kwisikhongozeli. Uxinzelelo lwe-intshi ye-1.5 ye-mercury iguqulela kwintloko epheleleyo ye-1.71 yeenyawo.

Imvelaphi: Isifunxa esigqibeleleyo simalunga ne-29.92 intshi zemekyuri.

9. Nxiba iRingi kunye ne-Impeller Clearance

Ukunxiba impompo. Xa izikhewu zinxiba kwaye zivula, zinokuba neziphumo ezibi kwipompo yokufunxa kabini (i-vibration kunye nemikhosi engalinganiyo). ngokuqhelekileyo:

Ukusebenza kwempompo kuya kuncipha inqaku elinye kwiwaka ngalinye le-intshi (0.001) kwi-clearance wear ye-0.005 ukuya kwi-intshi ye-0.010 (ukusuka kwindawo yokuqala).

Ukuphumelela kuqala ukuhla ngokukhawuleza emva kokuba i-clean igugile ukuya kwi-0.020 ukuya kwi-intshi ye-0.030 ukusuka kwimvume yokuqala.

Kwiindawo zokungasebenzi kakuhle, impompo imane iphazamisa ulwelo, iibheringi eziyonakalisayo kunye nezitywina kwinkqubo.

10. Uyilo lwecala lokufunxa

Icala lokufunxa yeyona nto ibalulekileyo kwimpompo. Ulwelo alunazo iimpawu/amandla okuqina. Ngoko ke, i-impeller yepompo ayikwazi ukwandisa kwaye ikhuphe ulwelo kwimpompo. Inkqubo yokufunxa kufuneka inike amandla okuzisa ulwelo kwimpompo. Amandla anokuvela kumxhuzulane kunye nekholamu engatshintshiyo yolwelo ngaphezulu kwempompo, isitya esicinezelekileyo / isikhongozeli (okanye enye impompo) okanye ngokulula ukusuka kuxinzelelo lomoya.

Uninzi lweengxaki zempompo zenzeka kwicala lokufunxa lempompo. Cinga ngenkqubo yonke njengeenkqubo ezintathu ezihlukeneyo: inkqubo yokufunxa, impompo ngokwayo, kunye necala lokukhutshwa kwenkqubo. Ukuba icala lokufunxa lenkqubo libonelela ngamandla olwelo olwaneleyo kwimpompo, impompo iya kujongana neengxaki ezininzi ezenzeka kwicala lokukhutshwa kwenkqubo ukuba ikhethwe ngokuchanekileyo.

11. Amava kunye noQeqesho

Abantu abaphezulu kuwo nawuphi na umsebenzi nabo bahlala bezama ukuphucula ulwazi lwabo. Ukuba uyayazi indlela yokufezekisa iinjongo zakho, impompo yakho iya kusebenza ngokufanelekileyo nangokuthembeka.
