Lub nplhaib ntu ntau theem twj tso kua mis (API610 / BB4)

1. Plhaub: Cov kab nruab nrab ntawm lub plhaub tau txais kev txhawb nqa kom muaj zog dua thiab lub sijhawm. Tsis tas yuav tsum muaj lub twj tso kua mis cua sov, thiab cov ntu nruab nrab tuaj yeem tapping rau hauv nruab nrab.

2. Impeller thiab qhia vane: Lub impeller thiab qhia vane yog precision cam khwb cia, nrog hydraulic qauv ntawm ntau yam tshwj xeeb speeds; kom ntseeg tau tias kev ua tau zoo dua thiab cov nqi khiav lag luam qis dua nyob rau hauv kev ua haujlwm dav dav, D80 (export) thiab cov lus qhia saum toj no tuaj yeem nruab nrog kev xaiv thawj-theem ob-suction impeller. Txhim kho vapor resistance NPSH

3. Ncej: Qhov tseem ceeb ceev yog siab tshaj qhov kev khiav hauj lwm ceev; lub staggered keyway transmits txaus torque thiab minimizes ncej deflection. Sab nrauv ntawm tus ncej yog tawv Cr-plated los tiv thaiv qhov chaw hnav.

4. Axial quab yuam sib npaug: Muaj ob hom impeller txheej txheem nyob rau hauv no series: ib tug yog lub impeller npaj nyob rau hauv series. Qhov sib npaug ntawm lub twj tso kua mis hauv cov qauv no siv lub nruas sib npaug (ib qho sib npaug nruas lossis nruas-disc-nruas) ntxiv rau cov kabmob thrust. Ntsuas lub zog axial. Cov qauv no tuaj yeem sib npaug ntawm axial quab yuam thiab txuas ntxiv lub neej kev pab cuam ntawm cov kabmob: Lwm qhov yog rov qab-rau-rov qab symmetrical kev npaj ntawm lub impellers, thiab lub zog axial yog txiav txim siab. Txij li cov qauv no tshem tawm cov kev ntsuas ntsuas, nws yog qhov tsim nyog rau kev thauj cov khoom uas muaj cov khoom siv. nruab nrab.

5. Bearings thiab lubrication: Cov kabmob hom tuaj yeem xaiv los ntawm tus kheej-lubricating qauv bearings lossis yuam lubrication qauv bearings raws li lub zog ncej thiab ceev. Lub thawv bearing tuaj yeem ua kiv cua-txias lossis dej-txias xaiv los ntawm.

6. Lub foob foob: Lub sealing system siv A1682 4th tsab (centrifugal twj tso kua mis thiab teb twj tso kua mis sealing system), thiab yuav configured nrog ntau yam ntaub ntawv ntawm sealing, flushing, thiab txias daws.
