How to Deal With Small Excavators Under High Temperature Conditions?

When the small excavator is in use, because the conditions are more complicated, we should not panic when encountering high temperature conditions. We should deal with it in time. Only in this way can we prevent the excavator from being damaged.

First of all, we judge the hydraulic high temperature failure of the excavator according to the method from simple to complex, from external to internal, from intuition to detection. 

The Failure Analysis and Processing Steps

First check whether the hydraulic oil radiator is dirty, hydraulic oil level, oil quality, check the filter element, if there is any problem, clean and replace it in time; check whether the hydraulic system leaks. If there are multiple leaks, please replace the seals and damaged parts in time.

Use a multimeter to check for circuit problems and sensor damage. Use a direct temperature tester to test whether the actual hydraulic oil temperature is too high.

The above inspection is normal. Check the return check valve of the hydraulic system. They should be removed to check if the spring is damaged or stuck. If you have any problems, you need to clean or replace them.

Check whether the hydraulic pump of the excavator has abnormal noise and excessive oil discharged from the drain pipe. If the working pressure is too low, use a pressure gauge to test the working pressure of the system; the above inspections belong to the normal inspection standards for small excavators. As long as a certain process is followed during the inspection, reasonable inspections of the excavators can be ensured and the occurrence of abnormal situations can be reduced.

Small Excavators are Mainly Used to Complete the Following Tasks

①Excavation of building and plant foundations;

②Loading operations in quarries, tunnels, underground powerhouses and stockyards; 

③Excavation of earth materials and stripping of the mining site cover; 

④Excavation of channels, canals and dredging waterways; 

⑤Pouring, lifting, installation, piling, ramming and other operations can be carried out after replacing the working device. Small excavators have a wide range of uses, but when any equipment fails, small excavators are naturally no exception. 

What Should be Paid Attention to in the Process of Repairing Small Excavators?

1.Parts decontamination and cleaning are not clean: The correct removal of oil and impurities on the surface of the parts plays an important role in improving the maintenance quality and prolonging the service life of the wheel excavator.

2.Change the oil in time. After the small excavator was overhauled, there were more impurities after trial operation. If the oil is not changed after cleaning, it is easy to accidentally burn the shaft.

3. The random use of bolts is very prominent: in the maintenance of excavators, because the performance and quality of the bolts do not meet the technical requirements, the bolt failures frequently occur, and the phenomenon of misuse is more prominent.

4. Irregular use of gaskets: The types of gaskets used in modern and old excavator parts vary greatly. When the excavator is repaired, the gasket is not standardized or even used randomly, which may cause leakage and looseness between the accessories, bolts, and nuts.

In short, the maintenance and repair of small excavators require more attention. In order to minimize the occurrence of failures, daily maintenance of small excavators is very necessary.
