Pump Adblue (Urea Dispenser)
Pump Adblue yog ib qho tshwj xeeb sau thiab ntsuas cov cuab yeej rau urea tov (AdBlue / DEF), tsim tshwj xeeb rau SCR tso tshuab ntawm cov tsheb diesel. Nws cov khoom tseem ceeb muaj xws li corrosion-cov twj tso kua mis tiv taus, siab- ntsuas qhov ntsuas qhov tseeb, thiab chav tswj ntse ntse, ua raws li ISO 22241 tus qauv rau purity thiab ntsuas.
I. Core txhais thiab daim ntawv thov
AdBlue: A 32.5% siab -purity aqueous urea tov siv hauv SCR systems los txo NOₓ emissions. Nws yog qhov yuav tsum tau ua rau cov tsheb diesel ntsib Tuam Tshoj IV / Euro IV lossis siab dua emission qauv.
Pump Adblue: Lub twj tso kua mis tshwj xeeb refueling unit. Kev siv cov twj siv hluav taws xob zoo tib yam yog txwv tsis pub siv (urea yog corrosive thiab nquag crystallization, thiab kev sib kis yuav ua rau SCR system puas).
Daim ntawv thov: Siv nyob rau hauv chaw nres tsheb roj, chaw nres tsheb logistics, tsheb thauj mus los, chaw nres nkoj, thiab lwm yam, txhawm rau sau urea rau cov tsheb thauj khoom, tsheb npav, kev tsim kho tshuab, thiab nkoj, nrog kev ntsuas qhov tseeb, tiv thaiv - pa phem, thiab tiv thaiv -crystallization functions.
II. Core Structure (Split / Integrated Hom)
1. Filling Pump (Core Component)
Hom: Diaphragm twj tso kua mis, iav twj tso kua mis, plunger twj tso kua mis (tus kheej-priming, urea corrosion resistant).
Khoom siv: 316L stainless hlau, engineering yas, Teflon seals; tooj liab, zinc, thiab txhuas tsis raug tso cai (kom tiv thaiv cov tshuaj tiv thaiv).
Siab: 0.3-0.6 MPa, ntws tus nqi 10-60 L / min.
Kev tiv thaiv - khov: Cov qauv rau sab qaum teb yog nruab nrog cua sov / taug qab los tiv thaiv crystallization hauv qab -11 ° C.
2. Metering thiab tswj
Flow meter: Turbine / oval iav flow meter, qhov tseeb ± 0.3% - ± 0.5%, nrog rau qhov kub thiab txias (urea ceev sib txawv nrog kub).
Tswj cov motherboard: Txhawb nqa ruaj khov- ntim / tsau-nqi / refueling dawb, tus kheej- xauv los tiv thaiv kev cuam tshuam, thiab txhawb nqa daim npav them nyiaj / QR code them / them nyiaj ntsuab.
Kev lim dej: Peb-theem filtration (coarse filtration → fine filtration → terminal filtration) los tiv thaiv SCR injectors.
3. Terminal Cheebtsam
Nozzle: Nruab nrog kaw -off valve, anti-drip muaj nuj nqi, thiab kev tiv thaiv tawg.
Pipeline: Tshwj xeeb urea pipeline nrog check valve thiab pom iav (los kuaj xyuas cov npuas npuas).
Txee: Sab nraum zoov los nag, plua plav, thiab tawg- pov thawj (yeem).
III. Cov txheej txheem ua haujlwm (Kaw-Loop Control)
Ntxig lub nozzle → txhais sensor → system tus kheej - tshuaj xyuas.
Lub cev muaj zog pib → twj tso kua mis tus kheej-priming → peb-theem pom → siab tsim-nce (0.3–0.6 MPa).
Tiag - lub sij hawm metering los ntawm flow meter → kub them → zaub / nqi.
Nres twj tso kua mis cia li thaum lub ntim ntim tau mus txog → pipeline backflow los tiv thaiv dripping.
Rub tawm lub nozzle → ua tiav, cov ntaub ntawv uploaded rau tom qab.
