What Are The Common Faults Of Rubber Paving Machine?

1. Check if the oil level in the fuel tank is too low

Experience has shown that excessive oil temperature is often caused by lack of oil in the fuel tank, so it should be replenished in time. Check if the Rubber Paving Machine hydraulic oil filter element and circuit are blocked. Whether the radiator is normal If the radiator is stuck with a large amount of dust, it may cause poor heat dissipation, and the oil temperature rises. The working environment of the Rubber Paving Machine is dusty, and the radiator should be cleaned in time. The quality of the hydraulic oil is qualified, the quality of the fuel is unqualified, and the system oil temperature is too high.

2, the screw conveyor does not work

Sometimes, due to the failure of the Rubber Paving Machine refueling system, the left and right spreader does not work, which causes the pressure of the charge pump system to be low: the charge pump inlet passage is not smooth; the charge pump relief valve pressure is low; the charge pump itself is faulty; Severe motor leakage In general, it is important to check the Rubber Paving Machine supplemental oil pump and its relief valve.

3, one side leveling hydraulic cylinder does not work

If the leveling hydraulic cylinder on the side of the Rubber Paving Machine does not work, it is usually caused by the lack of oil in the hydraulic cylinder on the side of the paver. The solenoid valve, the priority valve or the hydraulic cylinder inlet line may be blocked. In this case, first check the solenoid valve and the inlet pipe on this side of the Rubber Paving Machine, then check the priority valve.

4, Rubber Paving Machine deviates or cannot walk

When the Rubber Paving Machine can't walk, it is usually the paver that runs off or one side can't walk. This fault may be caused by loosening the solenoid valve of the control work pump. If the working pump on one side is unable to run due to power failure, When working, the traveling motor on one side will not work due to no oil, which may cause the Rubber Paving Machine to deviate or the side cannot walk.
