Pavers Hydraulic Oil Overheating

- Dec 28, 2018-

If the oil temperature of the paver hydraulic system is too high, the viscosity of the oil will decrease, the leakage will increase, the oil film of the lubricated part will be destroyed, and the wear of the parts will be intensified. At the same time, the high temperature will make the gasket made of rubber and other materials premature. Damaged by aging. Therefore, it is very important to control the proper oil temperature. When the oil temperature is too high, it is necessary to stop the inspection. Generally, the following aspects can be started:

(1) Check if the tank level is too low. Experience has shown that high oil temperatures are often caused by 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 and circuit are blocked.

(3) Is the radiator normal? If the radiator is stuck with a large amount of dust, it may cause poor heat dissipation and increase the oil temperature. Due to the dust in the working environment of the paver, the radiator should be cleaned up in time.

(4) Is the quality of the hydraulic oil qualified? If the quality of the added oil is unqualified, the system oil temperature will be too high.

In addition, the hydraulic system works when there is no oil, which is easy to cause damage to the pump and the motor. Therefore, after the oil shortage is eliminated, the operation state of the pump and the motor should be checked, and if necessary, the damaged parts of the pump and the motor should be replaced.
