As An Old Excavator Driver, Do You Know All These Excavator Parts?

1. The "Little Chimneys"
We often see a small chimney installed on some excavators. What is this small chimney used for?

This little chimney is called an air pre-filter. When the air quality is poor and the environment is bad, we will wear masks to isolate and filter the dust and impurities in the air to a certain extent. Like people, excavators also need to be protected.

The working environment of excavator is usually dusty, if dust, soil into the engine fuselage will cause engine failure. With the air pre-filter, the dust and impurities entering the air filter can be separated, so that the clean air enters the filter, and the maintenance time and service life of the filter can be prolonged, the engine intake quality can be improved, and the engine life can be prolonged.

How the air pre-filter works?
01. The outside air enters the air pre-filter through the screen mesh and rotates with the blades fixed at a specific angle.
02. When the air rotates, the super centrifugal force separates the dust and dirt.
03. Dust and impurities are driven by the inlet air flow and blown to the drain outlet by the fast rotating rotator.
04. Clean air enters the filter.

2. The small ring on the bucket.
The bucket is familiar to everyone, but what are the small rings on the bucket used for?

This small ring is the hook hole, the existence of the hook hole makes the excavator in addition to digging and more lifting function. Commonly used in the excavator hook hole for lifting operations are lifting stones, steel plates, mixers, telegraph poles and lifting pipes, and so on.

3. The “Small red circle”
Everyone knows the oil-water separator. However, at the bottom of these oil-water separators, you can often see a red disc similar to rubber. What is this?

The oil-water separator is generally installed on the fuel pipe of the diesel engine of construction machinery. Its function is to filter the water in the precipitated diesel and let the diesel enter the oil pump and engine. The red part in the oil-water separator is called a buoy, which is used to indicate the water content in the oil-water separator.

When the buoy in the oil-water separator floats, it means that a certain amount of water has been deposited inside. It is time to open the lower drain to drain the water.
