Luoyang Road Roller: What are the wear parts of a road roller?

【文章概要】Enhance the purification of both internal and external fuel. Such fuel contains a higher concentration of mineral impurities. When this fuel enters the three key components, it accelerates the rapid wear of the high-pressure oil pump, injectors, and delivery valves. So, for Luoyang road rollers: what are the worn parts? 1. To prevent and minimize this risk, it is essential to strengthen fuel purification both inside and outside the engine. 2. Pay close attention to and maximize the effectiveness of the air filter. The air filter must be kept in good condition and undergo regular maintenance, ensuring that clean air flows freely into the cylinders. 3. New machines and rollers that have undergone major overhauls require a break-in period. After break-in, replace the used oil, as abrasive particles are generated during this process.

Strengthen the purification of both internal and external fuels. Such fuels contain a higher concentration of mineral impurities. When these fuels enter the three major components, they accelerate the rapid wear of the high-pressure oil pump, fuel injectors, and delivery valves. So, for Luoyang road rollers: what are the worn parts of a road roller?

1. To prevent and mitigate this hazard, it is necessary to enhance purification both inside and outside the fuel engine.

2. Give due importance to and maximize the effectiveness of the air filter. Ensure the air filter is in good working condition and perform regular maintenance to allow clean air to flow freely into the cylinder.

3. New machines and overhauled drums require a break-in period. After break-in, the used oil should be replaced, as abrasive particles are generated during this process.

4. Reduce the formation of carbon deposits, which are a major cause of component wear. During engine disassembly, we often observe substantial carbon buildup on exhaust valves and in piston grooves. When carbon accumulates on valve seats and cylinder walls, it not only leads to severe leakage but also accelerates wear. If piston rings become seized by carbon deposits, they lose their elasticity, forcing them into tight contact with the cylinder wall and resulting in rapid wear during reciprocating motion. To improve engine operating conditions, it is essential to control carbon deposition.

5. Ensure both the quality and timeliness of maintenance. High‑quality maintenance is essential for minimizing wear and reducing the need for repairs, and it also plays a key role in slowing down wear on small rollers. During maintenance, pay particular attention to properly matching clearances: if the clearance is too small, friction increases, temperatures rise, and wear accelerates; if it is too large, lubricant leaks, an effective oil film fails to form, wear worsens, and impact on components leads to greater damage. The main maintenance tasks include adjustment, cleaning, and oil changes, with special emphasis on regularly removing contaminants from used oil. If the oil becomes excessively dirty, replace it sooner to ensure optimal oil quality. Typically, processes such as coloring, honing, and lapping can be employed.

A roller compactor manufacturer in Luoyang explains: Do small‑drum rollers require long‑term maintenance?

After prolonged use, operators learn how to maintain the rollers so they can perform optimally. In fact, if a roller remains idle for a month, it should undergo proper maintenance; otherwise, the machine may lose its elasticity.

1. Perform routine maintenance and rust-prevention treatments for long-term storage, in accordance with the engine’s specifications.

2. Clean both the inner and outer surfaces of the small roller. If possible, park it in a warehouse. For open-air parking, choose a well-ventilated area and cover it with canvas.

3. Lift the front frame horizontally and adjust the shim thickness until the damper block exhibits no shear or deformation whatsoever.

4. Secure the front and rear frames using a central articulated frame.

5. Add fresh lubricant or grease to each lubrication point on the drum.

A Luoyang road roller manufacturer explains what to do when the brake pressure of a road roller’s attachments is abnormal.

1. Oil leakage from the drum-type air compressor, excessive wear of the oil cylinder and piston rings, or sticking of the intake and exhaust valves. These issues reduce the compressor’s efficiency, result in insufficient air supply, and prevent the system from reaching the specified pressure.

2. Improper adjustment of the pressure on the roller‑type accessory brake valve can result in incorrect air working pressure. The normal operating pressure is 0.6–0.8 MPa. There are two main scenarios: First, if the pressure regulator—whether on the regulator itself or on a dryer equipped with one—is set too high or too low, adjust it by turning the adjusting screw on the regulator. Second, if the safety valve is set at an excessively high or low pressure, the safety valve will activate to relieve pressure and protect the cylinder when the cylinder pressure becomes too high. To adjust the safety valve, turn its adjusting screw. After making adjustments, be sure to verify that the pressure indicated on the pressure gauge is within the proper range.

3. Improper adjustment of the foot brake pedal causes it to bottom out, preventing the brake valve from fully opening and resulting in air throttling, which lowers the pressure downstream of the valve. In such cases, troubleshooting can be challenging. First, inspect the pedal to determine whether it contacts the base of the tower crane when fully depressed. If it does, this indicates insufficient pedal‑lever angle; the brake valve itself is likely functioning properly. If not, replace the brake valve.
