In modern road engineering construction, small road rollers have been widely used, not only in large construction sites, but also in urban road and infrastructure construction. The reason why small road rollers are so widely used is because of their extremely strong functionality and environmental adaptability.

However, it is inevitable that there will be construction failures due to various reasons during use. Taking effective methods to repair small rollers is a prerequisite for continued construction. For this reason, the editor summarizes common failures and learns that you are also a master of maintenance.

The common faults of small road rollers are summarized as follows

1

Leakage of engine oil: it may be due to the large wear and tear of the small roller parts, resulting in poor airtightness; the quality of the fuel itself, the concentration is not up to standard; there is a problem with the sealing parts; there is a large gap in the drive shaft.

2

When the hydraulic system of the small road roller is running, the pump body overheats: it may be due to problems with the pump body itself, such as extra exhaust and suction; the pump body is damaged and leaks.

3

The system pressure does not reach or has no pressure: it may be that the unloading port of the pilot relief valve of the small road roller is not blocked, resulting in no pressure in the control oil or no pressure in the hydraulic pump.

During construction, the running frequency of the small road roller suddenly decreases or there is an oil discharge failure. This phenomenon may be caused by the following reasons: the fuel volume of the small road roller is insufficient;
