What is the difference between a small road roller and a static pressure small road roller

①, the external structure is different
Small road rollers and static pressure rollers have different external structures. Small road rollers are divided into walk-behind single-drum rollers, walk-behind double-drum rollers, and ride-on rollers, while static-pressure rollers are compacted by rolling and compacting with their own gravity. Pave the layer to make it permanently deformed and dense.
②, the built-in structure is different
Small road rollers are obviously different from static pressure road rollers in their hydraulic cylinders and buffer devices. The static pressure small road rollers are equipped with buffer devices to buffer the huge impact force generated when the hydraulic cylinder suddenly stops at the end of the stroke, to avoid damage caused by the piston parts. The mechanical impact between the piston and the end cover caused by the inertial force and hydraulic pressure prevents damage to the structural parts of the static pressure road roller.
②, construction machinery compaction technology is different
The small road roller adopts the new vibration compaction technology to roll the road surface. The static pressure road roller adopts the method of rolling and compacting the pavement layer with its own weight in the 1990s. The pressures are all very different.
③, construction machinery environment is different
The static pressure road roller is used in the construction of soil with high water content. The small road roller should be used to roll the common road surface and require special engineering conditions. The road surface of this special nature should be rolled by a small road roller. If the soil moisture content is high Sometimes it will cause adhesion with the steel wheel of the road roller, resulting in incomplete road surface rolling and equipment wear, while the static pressure road roller uses its own weight for rolling, and the adhesion is relatively small.
④, the operation method is different
The static pressure road roller uses its own walking weight for rolling, and is equipped with forward and reverse gears. There are two gears of high vibration and low vibration, the equipment can walk independently, the operation is light and smart, and the practicability is wider.
