What are the characteristics of Luoyang road roller

Luoyang roller manufacturers believe that impact rollers are a new type of roller after smooth rollers and vibratory rollers. With its huge impact energy and high driving speed, it can achieve deeper compaction effect and higher compaction efficiency, and has been widely used in highway, railway subgrade and airport treatment.

Some knowledge points of Luoyang road roller

Luoyang road roller manufacturers believe that road rollers have wider requirements for filler moisture content, which can be reduced by 3%-5% in the up and down direction. Basically, after filling and leveling the soil, the advantages are more obvious, especially in arid or semi-arid areas. The moisture content in these areas is very low, some approaching 0%-1%. The impact roller only needs to spray a small amount of water on the surface to be rolled, which greatly reduces the compressed water and reduces the construction cost.

The characteristics of the road roller, Luoyang road roller manufacturers for you to explain

Luoyang roller manufacturers believe that in highways, railways, airports, water conservancy projects and construction projects, rollers are mainly used to compact roadbeds, pavements, dams, cofferdams, building foundations, etc. Small rollers are suitable for compacting narrow spaces. The so-called compaction means that through rolling and impact, external forces overcome the friction and cohesion between soil, sand, gravel, and asphalt mixture particles to rearrange themselves, move closer to each other, squeeze out water and air, and increase the friction between the material particles. and the cohesion becomes greater, the compacted material will be denser.

Some common sense of the road roller, Luoyang road roller manufacturers for you to solve the confusion

Luoyang roller manufacturer believes that impact rollers have many advantages that other equipment cannot match in construction. Low-frequency and high-amplitude impact rollers increase the compaction capacity of soil and stone; the rolling time is short, the speed is fast, and the consolidation is uniform; it is comparable to filling and strong compaction Compared with other products, the construction period is short, the construction is simple, the quality is reliable, and the cost is saved.

Some knowledge points of the road roller, Luoyang road roller manufacturers to tell you

Luoyang roller manufacturers believe that the vibration frequency of the roller is the number of times the roller vibrates per unit of time. The vibration frequency directly affects the compaction of the compaction foundation, and it is an important factor that affects the movement state of the compaction foundation material particles. Generally in a certain frequency range, the higher the vibration frequency, the better the road compaction effect.

Luoyang Roller: What are roller wear parts?

Enhanced purification of internal and external fuels. This fuel contains more minerals. When the fuel enters the three main parts, it accelerates the rapid wear of the high-pressure oil pump, injector and delivery valve, so Luoyang road roller: what are the wear parts of the road roller?1. In order to avoid and minimize this danger, it is necessary to strengthen the purification of the inside and outside of the fuel engine.2. Pay attention to and play the role of the air filter. The air filter must be in good condition and regularly maintained to allow pure air to enter the cylinder unimpeded.3. New machines and overhauled rollers need to be broken in. Change the dirty oil after break-in and form abrasive particles during break-in.

Road roller manufacturers talk about the development trend of impact rollers

With the development of highway technology and people's awareness, the application of trend technology is more and more, in the highway, the structure of the railroad roadbed and the role of impact pressure circuit can reduce the settlement and improve the strength and uniformity of impact rollers.
