YQB Series LPG Pump Cov Lus Qhia
I. Khoom Muag Khoom
YQB series muaj qhov zoo- zawv zawg zawv zawg qhov chaw-vane twj tsim tshwj xeeb rau kev hloov cov kua dej tsis zoo, flammable, thiab tawg xws li LPG, propylene, kua ammonia, thiab dimethyl ether. Lawv tau siv dav hauv cov ntawv thov suav nrog LPG tanker thauj khoom / tshem tawm, lub tog raj kheej sau, lub tank - mus rau - hloov pauv lub tank, thiab kev cob qhia khoom.
Qauv Tsim
YQB: LPG Pump
Tus lej (eg, YQB35-5): Rated Flow Rate (m³/h) - Rated Differential Pressure (kgf/cm²)
Cov yam ntxwv zoo
Stator nta ib qho kev nkhaus; rotor nruab nrog zawv zawg vanes, tsim 10 kaw chav.
Mechanical seals ntxiv rau O-rings ntawm ob qhov kawg kom tsis txhob xoom thiab qis -kub tsis kam.
Ua- nyob rau hauv kev nyab xeeb valve muab kev tiv thaiv tsis siv neeg rov qab tiv thaiv overpressure.
Kev tawg- pov thawj lub cev muaj zog haum rau thaj chaw muaj kev phom sij; siv los yog coupling tsav.

III. Yuav tsum tau nruab
1. Piping Configuration
Inlet: Nruab ib lub 30-40 mesh tooj liab hlau strainer (kwv thaj tsam loj dua los yog sib npaug rau 1.5 npaug ntawm qhov inlet yeeb nkab cheeb tsam) los tiv thaiv cov khib nyiab los ntawm lub twj tso kua mis.
Qhov hluav taws xob: Yuav tsum txuas cov kab rov ua dua tshiab (kev nyab xeeb valve rov qab mus rau lub tank cia); kev ua haujlwm nrog lub qhov hluav taws xob kaw tag nrho yog txwv tsis pub.
Flexible Connection: Siv 1–2m roj- cov roj hmab resistant hoses ntawm lub twj tso kua mis inlet thiab qhov hluav taws xob kom dampen vibration thiab tiv thaiv tawg.
Pipe Diameter: Inlet yeeb nkab txoj kab uas hla yuav tsum siab tshaj los yog sib npaug rau lub twj tso kua mis inlet txoj kab uas hla los tiv thaiv cavitation. 2. Kev nyab xeeb thiab Foundation
Xyuas kom ntseeg tau tias muaj kev ruaj ntseg hauv av thiab tawg - cov ntaub ntawv pov thawj rau lub twj tso kua mis thiab lub cev muaj zog.
Lub hauv paus yuav tsum yog theem thiab ruaj ntseg los tiv thaiv resonance.
Xyuas kom muaj qhov chaw zoo -ventilated; txwv tsis pub qhib nplaim taws; siv los tiv thaiv- ntsuas zoo li qub; nruab ib lub tswb hluav taws xob.
IV. Cov txheej txheem ua haujlwm
(I) Ua ntej- pib kuaj xyuas (yuav tsum tau)
Manually tig lub ncej (ntawm pulley / coupling) tsawg kawg yog 2 tag nrho lem; xyuas kom tsis muaj kev khi lossis suab nrov txawv txav.
Txheeb xyuas qhov kev sib hloov kom raug (qhia los ntawm xub xub ntawm lub twj tso kua mis lub cev; clockwise thaum saib los ntawm lub cev muaj zog kawg).
Qhib tag nrho cov inlet thiab recirculation li qub; me ntsis qhib lub qhov hluav taws xob valve; tshem tawm cua los ntawm lub twj tso kua mis thiab cov kav dej (yuav tsum tau pib pib lossis tom qab lub sijhawm kaw).
Txheeb xyuas tias cov ntsuas ntsuas siab thiab kev nyab xeeb li qub tsis zoo thiab tsis muaj qhov xau.
(II) Startup
Jog lub cev muaj zog kom paub meej tias muaj kev sib hloov thiab qhov tsis muaj qhov txawv txav.
Maj mam qhib lub qhov hluav taws xob lub qhov hluav taws xob thiab maj mam nce lub load rau qhov ntsuas siab (tsawg dua lossis sib npaug li 0.5-0.6 MPa).
Saib xyuas rau: ruaj khov siab, kev co me me, tsis muaj qhov xau, thiab tsis muaj suab nrov txawv txav.
(III) Kev Saib Xyuas Kev Ua Haujlwm
Siab: Inlet- qhov hluav taws xob sib txawv siab ** Tsawg dua lossis sib npaug li 0.49 MPa (5 kgf / cm²)**.
Kub: Twj lub cev Tsawg dua lossis sib npaug li 60 degree; xyuas kom tsis txhob overheating ntawm mechanical foob.
nruj me ntsis txwv kom qhuav khiav, cavitation (tswj cua / roj), los yog rov qab tig; kaw tam sim ntawd rau kev tshuaj xyuas yog tias tsis muaj kua ntws los ntawm qhov hluav taws xob.
Hloov lub tog raj kheej: Hloov lub tog raj kheej (qhov hluav taws xob tso siab tshaj lub twj tso kua mis); siab kwv yees li . 0.2 MPa; nres thaum lub tank puv.
(IV) Kev kaw
Kaw lub qhov hluav taws xob valve ua ntej, ces qhib tag nrho lub recirculation valve.
Txiav tawm lub hwj chim; tsis txhob ua qhov nres thaum muaj xwm txheej ceev thaum lub cev muaj zog.
Kaw lub inlet valve; Tshem tawm cov kua seem ntawm lub twj tso kua mis yog tias nws yuav tsis ua haujlwm rau lub sijhawm ntev.
V. Kev Tiv Thaiv Kev Nyab Xeeb (Cov ntsiab lus tseem ceeb)
Kev tawg- pov thawj & Kev Nyab Xeeb Hluav Taws Xob: Txwv tsis pub qhib nplaim taws thiab hluav taws xob zoo li qub hauv cheeb tsam; siv tawg-cov cuab yeej pov thawj thiab xyuas kom muaj kev ruaj ntseg hauv av.
Tiv thaiv Dry Running / Cavitation: Qhuav khiav rau 30 vib nas this tuaj yeem rhuav tshem lub foob; cavitation tuaj yeem ua rau lub impeller puas.
Recirculation Line Yuav Tsum Tau: Kev ua haujlwm yog txwv nruj yam tsis muaj kab rov ua dua; qhov kev nyab xeeb valve cia li qhib txoj kev recirculation thaum lub sij hawm overpressure.
Tiv thaiv kom qhuav kev sib txhuam ntawm Mechanical Seal: Sau cov kua thiab cov pa cua ua ntej pib; kaw tam sim ntawd rau kev saib xyuas yog tias muaj dej ntws tawm. Kev Tiv Thaiv Lub Caij Nplooj Ntoos Hlav: Tshem tawm cov kua dej seem thaum tsis ua haujlwm; tsis txhob siv lub tog raj kheej uas muaj dej hauv lub caij ntuj no los tiv thaiv cov dej khov.
VI. Kev tu
1. Txhua hnub (ib zaug ua haujlwm)
Txheeb xyuas qhov siab, vibration, to, thiab kub.
Ntxuav cov lim kom tsis txhob txhaws.
2. Periodic (hli/lub hlis twg)
Lubrication: Siv qis- roj roj rau cov kabmob; xyuas kom meej txoj siv tawv nruj thiab xyuas cov kab nrib pleb.
Seals: Mechanical seal to yuav tsum tsawg dua los yog sib npaug li 1 poob / feeb; hloov yog tias nws dhau qhov kev txwv no.
Kev Nyab Xeeb Valve: Txheeb xyuas qhov qhib siab (0.5-0.6 MPa).
3. Ntev -Lub sij hawm kaw
Tshem tawm cov kua seem thiab ntxuav nrog nitrogen rau kev tiv thaiv; khaws cia rau hauv qhov chaw qhuav, zoo - qhov cua.
VII. Tej Faults thiab Troubleshooting
Rooj
Fault Symptom Possible Cause Remedy
Tsis muaj kua tso tawm / Tsis tshua muaj ntws Cua hauv twj tso kua mis, inlet blockage, rov qab rotation, cavitation cua, huv si lim, kho rotation, replenish kua
Kev kub siab tshaj qhov hluav taws xob thaiv, recirculation valve kaw, kev nyab xeeb valve daig Clear qhov hluav taws xob, qhib recirculation valve, kev pabcuam kev nyab xeeb valve
Kev vibration / suab nrov tsis zoo Loose foundation, siv nruj heev, puas bearing, cavitation Tighten foundation, kho txoj siv, hloov bearing, tiv thaiv cavitation
Mechanical foob to Dry khiav, hnav, puas O- nplhaib Sau nrog kua, hloov foob, hloov O- nplhaib
VIII. Ceeb toom tshwj xeeb
Qhov no yog lub twj tso kua mis tawm qhov zoo; nruj me ntsis txwv tsis pub ua haujlwm nrog lub qhov hluav taws xob kaw tag nrho; txoj kab recirculation yog qhov tseem ceeb.
LPG yog nplaim taws thiab tawg; nruj me ntsis txwv tsis pub qhib nplaim taws, tiv thaiv hluav taws xob zoo li qub, thiab xyuas kom muaj cua nkag thaum lub sijhawm ua haujlwm.
Ua ntej txij nkawm, txiav lub hwj chim, depressurize, ntws cov kua seem, thiab ntxuav nrog nitrogen kom tsis txhob tawg lossis lom.
