These days, Wuhan, China, has been hot weather, the surface temperature is close to 60 degrees, and Wuhan is known as a world construction site, of course, there are also construction machinery like bulldozers, excavators, etc. This kind of hot weather is both for drivers and excavators. A test. Excavators often produce a variety of failures due to high temperature during operation. If the excavator driver can pay attention to the following points during the work of the excavator, it can effectively reduce the occurrence of excavator failures. Improve work efficiency.

　　1: Cooling down to prevent air resistance

　　The temperature in summer is high, and the engine is easy to show air resistance due to the high speed and hard heat dissipation, which makes it difficult to start the engine after stopping for a few minutes. Once air lock occurs, the excavator driver should stop immediately to cool down and eliminate the fault.

　　2: Observe the water temperature gauge at any time to prevent water shortage

　　Operate the excavator in high temperature weather, check the cooling water level before starting up, and check the water temperature gauge when working. If there is water shortage, it is necessary to replenish the coolant immediately. If the high temperature alarm is found, it should be processed after idling and cooling. When opening the radiator cover, pay attention to protection to prevent burns.

　　3: Prevent oil deterioration

　　The lubricating oil is easy to be thinned by heat, resulting in poor oxidation resistance, easy deterioration, and even failures such as burning tiles and shafts. Check the oil level and quality of the engine oil frequently, and replace them in time.

　　4: Clean the oil on the engine surface in time

　　If the external oil pollution of the engine is too thick, it will affect the heat dissipation and cause the failure of various parts to bury hidden dangers. The high-pressure injection method can be used to clean the engine parts with a cleaning agent that does not corrode the body parts.

　　5: Ensure effective heat dissipation of the radiator

　　In spring and summer, it is easy for catkins and other plant branches and leaves to be sucked into the radiator protection net and the narrow slits of the radiator, resulting in a decrease in ventilation capacity, resulting in high temperature of the engine. When summer comes, check and clean the radiator in time to ensure that the radiator protection net and fin wind The road is transparent.

　　6: Check the sponge seal around the radiator

　　In hot summer, check the sponge seal around the radiator. If there is damage and air leakage, it needs to be blocked or replaced, and it is cool for a summer.

　　The summer weather is hot. On the one hand, the driver is physically exhausted and easy to fatigue. On the other hand, the whole machine is also prone to failure due to high temperature. Therefore, the man and the machine should choose to work at peak shifts to avoid safety accidents!
