Excavator / Crane 3600 Rpm Hydraulic Closed Pump With 14 T 12/24 DP
The hydraulic closed pump in an excavator serves various important
purposes. Here are the primary uses of
the hydraulic closed pump in an excavator:
1 Bucket and Arm Operation: The hydraulic closed pump provides
power to control the movement of the
excavator's bucket and arm. It enables the operator to dig, scoop, and dump soil or other
materials efficiently.
2 Boom Movement: The hydraulic closed pump is responsible for
powering the movement of the excavator's boom.
It allows the operator to raise, lower, and extend the boom for reaching
different digging depths and positions.
3 Swing Operation: The hydraulic closed pump drives the swing
mechanism of the excavator, enabling it to rotate
horizontally. This functionality enables the excavator to cover a large area
without changing the machine's position.
4 Traveling Function: The hydraulic closed pump plays a crucial
role in the excavator's traveling function. It provides power to
the hydraulic motors or cylinders that drive the tracks or wheels,
allowing the excavator to move forward, backward, and turn.
5 Auxiliary Attachments: Many excavators have hydraulic systems
that power auxiliary attachments such as hydraulic breakers,
grapples, or augers. The hydraulic closed pump supplies the
necessary hydraulic pressure and control for these attachments
to perform their specific tasks.
In summary, the hydraulic closed pump in an excavator is essential
for controlling the bucket, arm, boom, swing,
and traveling functions of the machine. It enables efficient
digging, lifting, and maneuvering capabilities, making
the excavator a versatile and powerful construction equipment.
