The performance characteristics of Caterpillar 320D hydraulic
excavator are mainly reflected in the following aspects:
1. Component layout: Its hydraulic system and component locations
are specially designed to achieve a high level of system
efficiency. The main pump, control valve and hydraulic tank are
located close to each other, reducing the length of connecting
pipelines between components, thereby reducing friction losses and
pressure drops in the pipelines. In addition, the radiator is
arranged on the cab side of the superstructure. This layout helps
improve operator comfort by optimizing air flow and reducing engine
room heat and noise transferred to the operator.
2. Pilot system: Caterpillar 320D is equipped with an independent
pilot pump, which is independent of the main pump and is
responsible for controlling the front linkage mechanism, rotation
and driving, etc. This design makes operation more precise and
flexible.
3. Hydraulic interactive sensing system: The hydraulic interactive
sensing system can utilize each of the two hydraulic pumps under
all operating conditions, allowing 100% of the engine power to be
utilized. Productivity increases as implements speed up and pivot
faster and more forcefully
In addition, the engine model of the Caterpillar 320D hydraulic
excavator is Cat® C6.6 ACERTIM, with a flywheel net power of 103kW,
a bore of 105 mm, a stroke of 127 mm, and a displacement of 6.6L.
In terms of operating weight, the extended undercarriage ranges
from 21,830 kg to 21,900 kg, while the standard undercarriage
ranges from 20,660 kg to 21,310 kg.
In short, the Caterpillar 320D hydraulic excavator is a
well-designed excavator with excellent performance.
