Composition and principle of hydraulic pump
The hydraulic pump of excavator is the core component of the
hydraulic system of excavator, which undertakes the important task
of transporting hydraulic oil and providing power. Its efficient
stability and reliability provide a strong power support for
excavators.
Component composition:
Pump body: The pump body is the main part of the hydraulic pump of
the excavator, usually made of high strength cast iron or cast
steel. High pressure chamber and low pressure chamber are designed
inside the pump body. Through the structure of the pump body, the
suction and output of hydraulic oil are realized.
Drive shaft: The drive shaft is connected to the hydraulic pump and
the excavator's engine or motor, and the power is transferred to
the hydraulic pump to make it operate normally.
Rotor assembly: The rotor assembly consists of the main rotor and
the slave rotor, located between the high pressure chamber and the
low pressure chamber of the pump body. The meshing between the main
rotor and the slave rotor forms a sealed working chamber to realize
the suction and output of hydraulic oil.
Control valve assembly: The control valve assembly is used to
control the start and stop of the hydraulic pump, as well as to
regulate the output flow and pressure. These control valves are
usually controlled by mechanical or electrical systems to ensure
the stable operation of the hydraulic pump under different working
conditions.
How it works:
The working principle of excavator hydraulic pump is based on the
principle of volume change, usually using gear pump, plunger pump
or vane pump and other types.
Oil suction stage: In the low-pressure chamber of the pump body,
when the rotor assembly rotates, the volume of the low-pressure
chamber increases to form a negative pressure area. At this time,
the hydraulic oil is sucked into the pump body and enters the
hydraulic pump through the oil suction port.
Oil pressure stage: With the rotation of the rotor assembly, the
volume of the low pressure chamber gradually decreases, and the
hydraulic oil is compressed and enters the high pressure chamber of
the pump body. At the same time, the volume of the high pressure
chamber gradually increases, pushing the compressed hydraulic oil
to the high pressure pipeline of the hydraulic system.
Output stage: After the adjustment of the control valve assembly,
the compressed hydraulic oil in the high pressure chamber is output
to the hydraulic system to provide the required power for the
excavator. The hydraulic pump continues to work to maintain a
stable hydraulic oil output and ensure the efficient operation of
the excavator.
Excavator hydraulic pump is the core component of excavator
hydraulic system, its component composition and working principle
together constitute its efficient and stable power output. Through
the cooperation of the pump body, drive shaft, rotor assembly and
control valve assembly, the hydraulic pump realizes the suction,
compression and output of hydraulic oil, which provides a powerful
power source for the various work of the excavator.
