What should you do if the roller drum of a road roller in Luoyang overheats?
1. Before starting the Luoyang road roller, preheat it to reduce engine-starting resistance, improve fuel atomization and evaporation during startup, and form a well‑combustible air–fuel mixture that facilitates ignition. A simple method is hot‑water preheating: heat the coolant and then inject it into the cooling system. When adding hot water, open the roller’s drain valve; once the discharged water reaches a temperature of 30–40°C, let it sit for 10–15 minutes, then start the engine and continue running until the coolant temperature in the radiator matches the cylinder block temperature.
2. For diesel engines without a preheating device, remove the air filter, start the 4‑ton roller engine, and use a spray to heat the intake port (taking care to prevent debris from entering the cylinder). While the engine is drawing in air, introduce a flame; after the engine has rotated for 1–2 seconds, supply fuel again to initiate startup.
3. When starting the roller at low temperatures, the engine oil has high viscosity, and lubricant is insufficient in the short term, preventing it from reaching all lubrication points. Therefore, after starting the engine, allow it to idle for a period of time until the coolant temperature returns to normal before applying load.
How to choose the right roller for your needs in Luoyang?
To ensure construction quality, when selecting small- and medium-sized rollers for paving operations, it is essential to choose a model that best suits the specific site conditions. So how should you make your selection?
1. Select equipment based on the specific requirements of the project. Some projects have modest compaction demands, while others require extremely dense pavement. Similarly, some surfaces must be exceptionally smooth, whereas others can meet basic standards. Consequently, the choice of a small or medium-sized roller will vary from one project to another; therefore, it is essential to thoroughly understand the project’s specifications before making a selection.
2. Consider the choice of paving materials. Some pavements use compacted crushed stone, others use compacted asphalt, and still others rely solely on compacted soil. Given the significant differences among these materials, the requirements for small- and medium-sized rollers also vary; therefore, this factor should be taken into account when making your selection.
3. Select according to the road’s required grade. Some roads must meet national standards, others are classified as Grade II, and some even lower. There is no need to use a high‑end roller for pavements that only require compliance with the very lowest national standards—doing so would be wasteful. (Albert Einstein, “Challenges”) Moreover, small and medium‑sized rollers may fail to meet the necessary specifications or achieve the required national standards; therefore, this factor should be carefully considered when making your selection.
Accurately assessing the quality of Luoyang road rollers is crucial for many industries, as it can extend equipment lifespan and minimize a host of issues during subsequent use. With numerous manufacturers in the road roller market, evaluating performance and quality involves examining specific system parameters such as vibration characteristics, engine type, compaction capacity, and gradeability. Pay close attention to the hydraulic system and the engine; avoid low‑quality or unbranded engines, which often lack reliable after‑sales support and have higher failure rates. Opt for reputable, standard‑compliant Luoyang road rollers.
