In summer, the construction equipment of the construction site is easy to appear a failure phenomenon, that is the high temperature of the equipment, and in the excavator construction operation, the water temperature and the high oil temperature are very common phenomenon, and its effect on the performance and life of the machine is very large. Today, Li Shifu of the maintenance plant and the people talk about the "high temperature of the excavator and the high oil temperature". The cause of the barrier for the owners of the reference!
High water temperature and high oil temperature fault analysis of excavator
A phenomenon of high temperature and high temperature
When the thermostat is stuck, it can not be opened. At this point, the water can only go through a small cycle without passing through the radiator.
(2) the water in the water tank is dirty and the water is not smooth.
Fan speed is not enough, clutch failure. (or check belt tightness).
The rubber strip around the radiator is damaged. Eddy current will occur at this time, and the hot air will be recycled, so that the cooling effect can not be achieved.
Check whether the pump is working normally.
For this point, it is easy to ignore, that is, will it be false alarm, sensor problem, after all, the computer is only looking at the data and not looking at the facts.
High water temperature and high oil temperature fault analysis of excavator
Two hydraulic oil temperature high phenomenon
The main reason for the high temperature of hydraulic oil is excessive heat production or slow heat dissipation. The hydraulic pump inlet pipeline and the hydraulic oil tank are sealed not strictly, the oil inlet filter core is blocked, the hydraulic system pipeline is not smooth, the hydraulic pump internal leakage will make the hydraulic oil produce a large amount of heat, thus making the hydraulic oil temperature rise rapidly because of the excessive heat production. The hydraulic oil radiator is inside the radiator. Clogging, excessive external dust on the radiator, and hydraulic oil not passing the hydraulic oil radiator can cause high temperature of the hydraulic oil temperature due to the slow heat dissipation.
The above is the knowledge about "the high water temperature of the excavator and the high oil temperature fault", whether you are Caterpillar 320D, Komatsu PC200-8, Sany SY75C-9, BOBCAT337, SDLG LG6220, Doosan DH220LC-V, levo heavy industry FR75-7, Hitachi ZX200-3G, Volvo EC. 60C, Kubota KX135-3S, Liugong 906C, Kato HD820III, JCB8061, Sumitomo SH210-5, Yuchai YC60-8 and other excavators, if there is a difficult problem, please contact us!
