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.
Hydraulic pump operation manual
Thank you for choosing our excavator hydraulic pump products. This operation manual will provide you with detailed instructions and maintenance guides to help you fully understand and correctly operate the excavator hydraulic pump to ensure that it provides powerful power for your excavator efficiently and stably.
Product Overview:
Excavator hydraulic pump is the core component of excavator
hydraulic system, which is used to transport hydraulic oil and
provide power for hydraulic components. It has the characteristics
of high flow output and high pressure stability, and is suitable
for various excavator models and application scenarios.
Safety Information:
Before operating the hydraulic pump of the excavator, be sure to
carefully read and follow the following safety instructions:
Before operation, ensure that the excavator is in a stable shutdown
state and cut off the power source.
It is strictly prohibited to open the cover plate of the hydraulic
pump or remove key components during operation.
When maintaining and maintaining hydraulic pumps, relevant safety
procedures and operating regulations must be observed.
Operation steps:
Follow these steps to properly operate the excavator hydraulic
pump:
Step 1: Ensure that the hydraulic pump and excavator are shut down and cut off the power source.
Step 2: Check the liquid level of the hydraulic pump to ensure that the hydraulic oil is within the appropriate mark line range.
Step 3: Start the power source of the excavator, slowly increase the speed of the hydraulic pump, so that it reaches the normal working state.
Step 4: According to the actual work needs, adjust the output flow and pressure of the hydraulic pump to ensure that it meets the work requirements.
Step 5: During the work of the excavator, pay attention to monitoring the operating status of the hydraulic pump, and stop the machine in time for inspection if there is an anomaly.
Maintenance:
In order to ensure the normal operation of the hydraulic pump of
the excavator, regular maintenance is very important. Here are some
suggestions:
Check the liquid level of the hydraulic pump every day, and add
hydraulic oil in time.
Replace the hydraulic oil regularly and clean the tank and filter.
Check the seals and connecting parts of the hydraulic pump to
ensure that there is no oil leakage.
Check the operating status and pressure of the hydraulic pump
regularly, and deal with any anomalies in time.
Troubleshooting:
During use, if the hydraulic pump is abnormal, you can
preliminarily eliminate it according to the following methods:
If the hydraulic pump oil leakage is found, check whether the seal
is damaged and replace it in time.
If the hydraulic pump appears noise or vibration, check whether the
pump body and connecting parts are loose.
If the output flow of the hydraulic pump is unstable, check whether
there is blockage or pump body damage.
If you can not solve the problem, please contact our after-sales
service team in time, we will provide you with professional
technical support.
