Causes of blockage of hydraulic oil circuit of vibratory roller

During the construction process of vibratory rollers, blockage of the hydraulic oil circuit is a common problem. The hydraulic oil circuit is an important part of the hydraulic system of the road roller, and its normal operation is directly related to the normal operation and performance of the road roller. When the hydraulic oil line is blocked, the operation of the roller will become difficult and may even lead to equipment failure. Therefore, it is crucial to understand the causes of blockage in the hydraulic oil circuit of vibratory rollers and to take appropriate measures.

1. Reasons for blockage of hydraulic oil circuit

1. Hydraulic oil pollution: Impurities and pollutants in hydraulic oil are one of the main causes of blockage of hydraulic oil lines. These impurities may come from the manufacturing, storage and use of hydraulic oil, such as metal shavings, rubber particles, moisture, etc.
2. The temperature of the hydraulic oil is too high: High temperature will evaporate the water in the hydraulic oil and form water vapor, causing bubbles and blockage in the hydraulic oil circuit. At the same time, high temperature will also accelerate the oxidation and deterioration of hydraulic oil, further aggravating the blockage of hydraulic oil lines.
3. Wear of hydraulic components: Wear of hydraulic components will lead to leakage and contamination of hydraulic oil, which will lead to blockage of the hydraulic oil circuit.
4. Unreasonable design of the hydraulic system: If the design of the hydraulic system is unreasonable, such as insufficient tank capacity, unreasonable pipeline layout, etc., it will cause pressure fluctuations and unsmooth flow in the hydraulic oil circuit, which will lead to blockage of the hydraulic oil circuit.

2. Measures to Prevent Blockage of Hydraulic Oil Lines

1. Control the quality of hydraulic oil: Use high-quality hydraulic oil, and regularly check and replace the hydraulic oil to avoid impurities and pollutants in the hydraulic oil from blocking the hydraulic oil line.
2. Control the temperature of the hydraulic oil: Reasonably design the hydraulic system to ensure the cooling effect of the hydraulic oil. At the same time, clean the radiator regularly to maintain its good heat dissipation performance.
3. Regularly inspect and repair hydraulic components: Regularly inspect and repair hydraulic components, and promptly replace seriously worn components to avoid leakage and pollution from blocking the hydraulic oil circuit.
4. Optimize hydraulic system design: During the design and manufacturing process, the rationality and reliability of the hydraulic system should be fully considered, such as rationally arranging pipelines, increasing tank capacity, etc., to reduce pressure fluctuations and poor flow in the hydraulic oil circuit. .

In short, there are many reasons for the blockage of the hydraulic oil line of the vibratory roller. In order to prevent the blockage of the hydraulic oil line, we need to start from many aspects, including controlling the quality of the hydraulic oil, controlling the temperature of the hydraulic oil, regularly inspecting and repairing the hydraulic components, and optimizing the hydraulic pressure. System design, etc. Only in this way can the normal operation and performance of the road roller be ensured and its service life extended.
