1. IiMfuno zemibhobho yePump Suction kunye ne-Discharge Piping

1-1. Yonke imibhobho eqhagamshelwe kwimpompo (uvavanyo lokugqabhuka kombhobho) kufuneka ibe nezixhaso ezizimeleyo neziqinileyo zokunciphisa ukungcangcazela kombhobho kunye nokuthintela ubunzima bombhobho ekubeni ucinezele impompo.

1-2. Izibiyeli ezilungelelanisiweyo kufuneka zifakwe kwimibhobho yokungena kunye nokuphuma kwempompo. Kwimibhobho ene-vibration, iibrakethi zokudambisa kufuneka zifakwe ukulungelelanisa ngokufanelekileyo indawo yombhobho kunye nokunciphisa amandla ongezelelweyo kumbhobho wempompo obangelwa iimpazamo zofakelo.

1-3. Xa umbhobho odibanisa impompo kunye nezixhobo zifutshane kwaye ezimbini zingekho kwisiseko esifanayo, umbhobho odibanisayo kufuneka ube bhetyebhetye, okanye umbhobho wentsimbi kufuneka wongezwe ukuhlawulela ukuhlaliswa kokungalingani kwesiseko.

1-4. Idayamitha yokufunxa kunye nokukhupha imibhobho akufunekanga ibe ncinane kunokungena kwimpompo kunye nedamitha zokuphuma.

1-5. Umbhobho wokufunxa wempompo kufuneka udibane nenetha yentloko yokufunxa evumayo (NPSH) efunwa yimpompo, kwaye umbhobho kufuneka ube mfutshane kangangoko ngokujika okumbalwa. Xa ubude bombhobho budlula umgama phakathi kwesixhobo kunye nempompo, nceda ubuze inkqubo yenkqubo yokubala.

1-6. Ukuze kuthintelwe i-cavitation yepompo yokufunxa kabini, ukuphakama kombhobho we-nozzle we-inlet ukusuka kwisixhobo ukuya kwimpompo kufuneka kuthotywe ngokuthe ngcembe, kwaye kungabikho u-U-shaped kwaye phakathi! Ukuba ayinakuphepheka, i-valve yokuphuma kwegazi kufuneka yongezwe kwindawo ephakamileyo, kwaye i-valve yokukhupha kufuneka yongezwe kwindawo ephantsi.

1-7. Ubude becandelo lombhobho othe tye phambi kokungena kwempompo yempompo ye-centrifugal akufanele ibe ngaphantsi kwe-3D ye-diameter yokungena.

1-8. Kwiimpompo zokufunxa kabini, ukwenzela ukuba ugweme i-cavitation ebangelwa ukufunxa okungalinganiyo kumacala omabini, imibhobho yokufunxa kabini kufuneka icwangciswe ngokulinganayo ukuze kuqinisekiswe ukusasazeka kokuhamba kumacala omabini.

I-1-9 Ukulungelelaniswa kombhobho ekupheleni kwempompo kunye nokuqhubela phambili kwempompo yokubuyisela akufuneki kuthintele ukuchithwa kunye nokugcinwa kwepiston kunye nentonga yokubopha.

2. UkuSetwa koMbhobho oNcedisayo weUkwahlula Impompo yeCase

2-1. Umbhobho wempompo ofudumeleyo: Xa ubushushu bemathiriyeli yempompo ye-centrifugal bungaphezu kwama-200 °C, kufuneka kufakelwe umbhobho wempompo ofudumeleyo ukuze umthamo omncinane wezinto ukhokelwe ukusuka kumbhobho okhuphayo wempompo yokusebenza ukuya kwindawo yokuphuma. impompo yokulinda, emva koko iqukuqele kwimpompo yokulinda, ize ibuyele kwisiziba sempompo ukwenza impompo yokulinda Impompo ikwimo yokulinda eshushu ukuze iqalise ngokulula.

2-2. Imibhobho ye-Anti-condensation: I-DN20 25 imibhobho echasene nomkhenkce kufuneka ifakwe kwiimpompo ezinomgangatho odibeneyo kwiqondo lokushisa eliqhelekileyo, kwaye indlela yokumisela iyafana neyombhobho wempompo efudumeleyo.

2-3. Umbhobho olungelelanisayo: Xa isiphakathi siqhelene nokufakwa komoya kwindawo yempompo, umbhobho olungeleleneyo onokubuyela kwisithuba sesigaba segesi sesixhobo esinyukayo kwicala lokufunxa unokufakelwa phakathi kombhobho wokungenisa impompo kunye nevalve yokuvala isingeno sempompo. , ukwenzela ukuba irhasi eveliswayo ikwazi ukubuyela emva. Ukuze ugweme i-cavitation yepompo, i-valve yokusika kufuneka ifakwe kumbhobho webhalansi.

2-4. Ubuncinci bombhobho wokubuyiswa kwempompo: Ukuze kuthintelwe impompo ye-centrifugal ukuba isebenze ngaphantsi komlinganiselo omncinci wokuhamba kwempompo, ubuncinane bombhobho wokubuyiswa kwempompo kufuneka usetelwe ukubuyisela inxalenye yolwelo olusuka kwizibuko lokukhupha impompo kwisikhongozeli esahlulweni. icala pump suction port ukuqinisekisa izinga lokuhamba kwempompo.

Ngenxa yobungcali bempompo, kuyimfuneko ukuqonda ngokupheleleyo ukusebenza kwempompo kunye nezixhobo zenkqubo ezisebenza kwimpompo, kunye nokulungelelaniswa okufanelekileyo kwemibhobho yayo yokungena kunye nokuphuma kuyadingeka ukuze kuqinisekiswe ukusebenza kwayo okukhuselekileyo kunye nokuzinza. .
