Are second-hand small rollers reliable?

The small roller is driven by a fully hydraulic rear tire, which ensures stable performance and safer construction. It can handle various road conditions with ease, and it can be said that different work scenarios can be completed as desired. Small rollers can also use infinitely variable speeds, which are easy to operate. How simple can it be? One-lever control can control the vehicle forward, backward, speed, and parking. It sounds simple, but in fact, the operation is even simpler, and the panel settings are clear at a glance.

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.
