Raws li cov khoom siv tseem ceeb hauv kev tsim kho niaj hnub no, kev pabcuam lub neej ntawm cov tsheb thauj khoom -mounted qhob twj tso kua mis ncaj qha cuam tshuam qhov project efficiency thiab kev tswj tus nqi.
Cov cuab yeej siv niaj hnub muaj li ntawm 8 mus rau 12 xyoo lossis 6,000 txog 8,000 cubic meters ntawm kev xa khoom ua vaj tse, cuam tshuam los ntawm plaub yam tseem ceeb: kev siv siv, kev tu zoo, kev ua haujlwm ib puag ncig, thiab kev ua haujlwm ua raws. Kev ua haujlwm siab -ntau zaus (ntau tshaj 8 teev txhua hnub) ua kom nrawm nrawm ntawm cov khoom tsis zoo. Kev ua haujlwm tsis tu ncua yuav tsum tsis pub dhau 12 teev, nrog rau 15-feeb so tau teem sijhawm txhua 2 teev ua haujlwm. Kev ua raws li kev saib xyuas nruj tuaj yeem txo qis tus nqi tsis ua haujlwm los ntawm 67% thiab txuas ntxiv lub sijhawm hloov kho los ntawm 2 txog 3 xyoos. Nyob rau hauv ib puag ncig corrosive (piv txwv li, ntug hiav txwv ntsev tsuag zones) los yog huab cua kub (hauv qab -20℃/ siab tshaj 40 degree), hlau qaug zog nce los ntawm 30% mus rau 50%. Kev ua haujlwm tsis raug cai (piv txwv li, pib / nres hauv qab load, overpressure pumping) account rau 42% ntawm qhov tsis ua haujlwm loj, nrog rau cov twj tso kua mis kev puas tsuaj yog qhov tshwm sim ntau tshaj.
To extend equipment lifespan, implement a tiered maintenance system with refined upkeep measures. Daily maintenance should focus on three core modules: hydraulic, conveying, and electrical systems: - After daily operation, check hydraulic oil level (maintain 1/2 to 2/3 of sight glass), oil temperature (≤70°C), clean radiator surface, and monitor pressure gauge fluctuations (normal pumping pressure 10-18MPa); Clean residual concrete from the S-tube, wear plate, and cutting ring; adjust the gap between the hopper mixing blades (address gaps >5mm); lubricate all bearing points with No. 2 lithium-based grease. Simultaneously, tighten electrical system terminals, measure insulation resistance (>0.5MΩ), kuaj cov chaw taws teeb tswj kev nkag siab, thiab hloov pauv lub laub - khawm hloov.
Periodic maintenance (every 500 hours or 3 months) requires in-depth hydraulic system servicing: replace #68 anti-wear hydraulic oil and filter element, clean the oil tank, and calibrate the main relief valve pressure (tolerance ±2%); Replace wear parts according to standard intervals, such as rubber springs (800 hours), conveyor pistons (1500 hours), and tank seals (1000 hours). Accurately assess component condition through visual crack inspection, hardness testing, outer diameter wear measurement (replace if >2mm), thiab ntsuas hydraulic siab (0.3MPa siab tuav). Tsis tas li ntawd, tshuaj xyuas boom welds (tsom mus rau pob khawm), outrigger levelness (tolerance)<1°), and weighing system accuracy (tolerance ≤1%). Seasonal maintenance requires environmental adjustments: - Winter (below -10°C): Replace with -30°C low-temperature hydraulic oil, drain and refill water tank with antifreeze, preheat for 15 minutes before startup (oil temp ≥20°C); In summer (above 35°C), increase radiator cleaning frequency (once weekly), install sunshades to control dashboard temperature (<50°C), and verify automatic cooling fan start/stop functionality.
Txhawm rau txuas ntxiv cov cuab yeej siv lub neej, koom ua ke kev tswj hwm digital nrog kev ua haujlwm zoo. Tsim cov ntaub ntawv kho mob cov cuab yeej siv cov tshuab digital los sau cov tsos mob tsis raug, kho cov kev daws teeb meem, thiab hloov qhov chaw, siv cov ntaub ntawv loj analytics los kwv yees qhov ua tsis tiav. Ua raws li cov txheej txheem kev tu vaj tse uas faib ua peb theem: Theem A (kev kuaj xyuas txhua hnub thiab kev hloov kho), Qib B (kev tshuaj xyuas txhua hli thiab cov khoom siv lubrication), thiab Qib C (txhua xyoo kev tshem tawm thiab kev kho kom zoo). Kev cob qhia tus neeg ua haujlwm tsis tu ncua tsom rau cov tswv yim hloov pauv hloov pauv hloov pauv (pib hloov pauv tsawg dua lossis sib npaug li 50%), cov yeeb nkab thaum muaj xwm txheej ceev- cov txheej txheem thaiv (rov qab tso dej ua tiav li ntawm 3 feeb), thiab cov qauv kev hloov pauv hloov pauv (12-18cm pom zoo). Ib txhij txhim kho cov khoom seem tswj hwm los ntawm kev tsim kom muaj kev nyab xeeb rau cov khoom hnav (3-hli lub voj voog), siv cov khoom pov thawj OEM (xws li, Rexroth hydraulic qhov chaw, HBM load cells), thiab tshawb xyuas cov txheej txheem kho dua tshiab rau cov khoom siv (xws li, electroplating kho rau piston rods). Kev xyaum qhia tau hais tias kev ua raws li txoj kev npaj no txuas ntxiv lub sijhawm hloov kho loj mus rau ntau dua 15,000 teev thaum txo cov nqi kho txhua yam los ntawm 35%. Nws raug nquahu kom ua cov cuab yeej ntsuas kev noj qab haus huv peb lub hlis twg thiab txuas ntxiv kho cov tswv yim txij nkawm kom ua kom cov cuab yeej muaj txiaj ntsig tag nrho ntawm lub neej.
