Summer is here, the heat is hot, the driver, the excavator, is a test. High temperatures, excavators in the process of operation often due to high temperatures and a variety of failures, excavator drivers in the excavator work process, if you can pay attention to the following points, it can effectively reduce the generation of excavator failure. Excavator action is complex, all agencies often start, brake, change direction, load changes, shock and vibration frequently, and field operations, temperature and astronomical position changes, coupled with the hot weather in the summer, and therefore based on the work characteristics of the excavator and environmental characteristics, the excavator engine should pay attention to heat dissipation, while the hydraulic system should do.

(1) effective transmission efficiency, in order to give full play to the dynamics of the engine and the economy of fuel use.

(2) hydraulic system and hydraulic components in the load changes, rapid vibration shock, with sufficient reliability.

(3)Coordinate the bulky and vibration-resistant cooler to reduce the total heat generation of the system so that the hydraulic oil temperature does not exceed 80 degrees when the main engine continues to work, or the temperature rise does not exceed 45 degrees.

(4) Due to the excavator site dust, hydraulic oil is easy to be polluted, thus the sealing performance of the hydraulic system should be good, the hydraulic components have low sensitivity to oil pollution, and the whole hydraulic system should be set up with oil filters and dustproof installation.

(5) The use of hydraulic or electro-hydraulic servo domination installation, so that the excavator set up automatic control system, and then progress to improve the technical performance of the excavator and reduce the labor intensity of the driver.
