I. Khoom Parameters
Basic Specifications
Loj Tsim
Txais yuav optimized 400mm × 500mm sab nrauv dimension nrog 50mm phaj thickness, no grate npog 1.5-2.0 square meters ntawm qhov chaw dej. Txaus thickness muab cov khoom txhawb nqa thiab kev ruaj ntseg tag nrho.
Load Classification
Ob qib kev thauj khoom tseem ceeb npog cov kev xav tau hauv nroog. B125 tiv taus 12.5 tons rau txoj kev taug kev thiab chaw ua lag luam. D400 zam 40 tons rau kev tsheb hauv nroog. Spheroidal graphite qauv muab ob npaug rau tensile kev ua tau zoo tshaj cov tsoos cam khwb cia hlau.
Khoom Txheem
Ua nrog tus qauv QT500-7 cov hlau nplaum. Tswj cov ntsiab lus carbon 3.6% -3.8%, silicon cov ntsiab lus 1.8% -2.2%, thiab spheroidization tus nqi siab tshaj 85%, ntsuas qhov toughness thiab lub zog ntawm cov qauv.
Txheej txheem thiab kev ua tau zoo zoo
Precision Manufacturing Workflow
Txais cov txheej txheem ua ke: pwm casting, 900℃normalizing kev kho cua sov thiab tiv thaiv- xeb hmoov txheej. Kev tswj qhov nruj nruj kom ntseeg tau tias burr- cov npoo dawb, nrog kev sib dhos ncaj nraim tswj tsis pub dhau 2 hli.
Superior Corrosion Resistance
Kev sib xyaw asphalt tiv thaiv txheej thiab cov khoom siv ntuj acid- puag ruaj khov, cov khoom dhau 480- teev ntsev tshuaj tsuag yam tsis muaj xeb. Nws yoog tau zoo rau cov ntug dej hiav txwv ntsev-huab thiab cov chaw ua si tshuaj corrosive ib puag ncig.
Ua kom muaj peev xwm ua tau dej
Hollow grille cheeb tsam tso nyiaj rau 40% -45% ntawm tag nrho cov phaj. Cov dej ntws tawm tam sim no nce mus txog 0.3m³ / min, ntws tawm sai sai thaum lub sij hawm luv luv - lub sijhawm los nag hnyav.
Optimized Safety Structure
Deg tiv thaiv-slip zoo nkauj qhov tob tshaj 1.5mm rau kev nyab xeeb dua. Matched lub kaum sab xis steel ncej xauv cov qauv txiav cov kev pheej hmoo tub sab nyiag los ntawm 80%.
II. Scenario Adaptation thiab xaiv Logic
1. Cov xwm txheej ntawm daim ntawv thov
| Hom Scenario | Adaptation Qib | Kev xav tau |
| Khw / Pedestrian Street | B125 | Cov neeg taug kev siab ntws, tiv thaiv - plam & ntsiag to |
| Municipal Secondary Road | D400 | Lub teeb tsheb dov, ceev dej ntws tawm |
| Underground Garage nkag | D400 | Kev daws teeb meem, corrosion kuj |
2. Qhov taw qhia xaiv qhov tseem ceeb
Load Matching Txoj Cai
A15 / B125 rau ko taw kev tsheb ciav hlau; C250 / D400 rau kev tsav tsheb. Kev xaiv qib tsim nyog zam kom tsis muaj peev xwm ntawm cov kabmob thiab kev puas tsuaj.
Hydraulic Adaptation
Ib qho grate haum qhov chaw nkag hauv 20㎡. Ntau cov grate tau teeb tsa rau cov cheeb tsam los nag, nrog cov yeeb nkab hauv qab qhov sib piv tau khaws cia siab tshaj 1: 3 kom lav cov dej tsis muaj kev cuam tshuam.
Environmental Adaptability
Kub-dip galvanized tiav rau ntug dej hiav txwv ntsev tsuag; Ntxiv epoxy txheej rau tshuaj lom neeg thaj tsam tiv thaiv acid thiab alkali yaig.
III. Installation and Maintenance Guide
1. Txheej txheem kev teeb tsa
1
Lub nplhaib 20cm tuab yog cam khwb cia siv C25 pob zeb, nrog rau ua ntej - embedded lub kaum sab xis steel thav duab rau fixation, kom ntseeg tau tias kab rov tav yuam kev tsawg dua los yog sib npaug li 3 hli;
2
Qhov saum npoo ntawm cov grate yog 3-5 hli qis dua qhov chaw ntawm txoj kev kom tsis txhob muaj dej tsub zuj zuj thiab suab nrov ntawm pob. Cov khoob khoob yog ntim nrog cov cement mortar;
3
Asphalt pavements yog them nrog cov ntawv hlau thaum lub sij hawm tsim kho, thiab cov cement pavements raug tiv thaiv nrog cov yas zaj duab xis los tiv thaiv qhov chaw paug.
2. Kev tu lub neej tag nrho
Kev tshuaj xyuas txhua hnub:
Kev tshuaj xyuas txhua hli rau kev xoob thiab kev puas tsuaj. Ua ntej lub caij los nag, tsom rau kev tu cov nplooj poob, av nkos, thiab lwm yam thaiv kom muaj dej ntws zoo;
Kev daws teeb meem:
Me deformation tuaj yeem kho nrog cua sov. Cov kab nrib pleb tob dua 5 hli yuav tsum tau hloov tam sim kom tsis txhob muaj kev nyab xeeb;
Lifespan:
Raws li kev saib xyuas ib txwm muaj, lub neej kev pabcuam tuaj yeem ncav cuag 30 xyoo, 50% ntev dua li cov khoom siv hlau cam khwb cia.
