What are the methods to extend the service life of excavator cooling devices and maintain good performance

1. Dirty condenser

If the compressor is dirty, the heat dissipation effect will decrease. Please clean it with water, etc.

Attention: Please do not use high-pressure water to clean the condenser.

The condenser installed in front of the radiator is particularly prone to accumulating dirt, please wash it with water.

2. Tension point inspection of V-belt

If the tension of the V-belt is loose, the service life of the V-belt will be significantly reduced due to the sliding and shaking of the belt. Please check whether the V-belt is loose by hand pressure.

3. Inspection of piping connection points

Please visually confirm the oil penetration, dirt and dust adhesion of each connecting part of the cooling device.

4. When reusing after a long period of inactivity

·Conduct a comprehensive inspection of all aspects of the "cooling device inspection".

·When starting the cooling device, please do not sharply increase the speed of the compressor.

Attention: In order to extend the service life of the cooling device and maintain good performance, it is recommended to use preventive maintenance inspection during the initial use.

5. Operation during off-season (infrequent use)

·Regardless of summer or winter, please install the cooling device components and add refrigerant. But second-hand excavators should pay more attention to this point.

Attention: Regardless of summer or winter, please install the drive belt of the compressor properly.

6. When not in use for a long time

·Please run the cooling device 1-2 times every 2-3 weeks.

It has the effect of preventing leakage at the oil seal of the compressor. In addition, it can prevent oil leakage from the components, which helps maintain the performance and service life of the compressor.
