What are the common technical failures of paver machines?

Hydraulic oil overheating: If the oil temperature of the hydraulic system of the paver is too high, the viscosity of the oil will decrease, the amount of leakage will increase, the oil film on the lubricated parts will be destroyed, and the wear of the components will increase. At the same time, high temperature will also cause damage to parts made of rubber and other materials. The gasket is damaged due to premature aging. Therefore, it is very important to control the appropriate oil temperature. When the oil temperature is too high, the machine must be shut down for inspection. Generally, the following aspects can be considered: (1) Check whether the liquid level in the fuel tank is too low. Experience shows that high oil temperature is often caused by a lack of oil in the fuel tank, so it should be replenished in time when there is a lack of oil.
(2) Whether the hydraulic oil filter element and circuit are blocked.
(3) Whether the radiator is normal. If a large amount of dust adheres to the radiator, it can lead to poor heat dissipation and increase the oil temperature. Since the working environment of the paver is dusty, the radiator should be cleaned in time.
(4) Whether the quality of hydraulic oil is qualified. If the quality of the added oil is not up to standard, it will also cause the system oil temperature to be too high. In addition, when the hydraulic system works when there is a lack of oil, it is easy to cause damage to the pump and motor. Therefore, after troubleshooting the oil shortage, you must also check the operating status of the pump and motor, and replace damaged parts of the pump and motor if necessary. 2. The auger spreader does not work: Sometimes the left and right spreaders of the paver do not work. The reason is usually that the oil supply system is faulty. The reasons for low pressure in the oil charge system include: poor oil inlet passage of the oil charge pump; low pressure in the relief valve of the oil charge pump; failure of the oil charge pump itself; and serious leakage of the hydraulic motor. Generally, you should focus on checking the charge pump and its relief valve. Note: When using the paver, proper maintenance of the hydraulic system can greatly reduce failures.
