Product internal structure and working principle
Excavator hydraulic control valve is an important part of excavator
hydraulic system, which plays a key role in regulating hydraulic
oil flow and pressure. A thorough understanding of the internal
structure and working principle of the hydraulic control valve is
helpful to understand the operation mechanism of the excavator
hydraulic system.
First, the internal structure of the hydraulic control valve:
Reversing spool: It is the core component of hydraulic control
valve, which changes the channel of hydraulic oil by moving up and
down and left and right to achieve the control and adjustment of
hydraulic system.
Spring: Used to control the position of the reversing spool to
ensure that the hydraulic control valve returns to a neutral
position when it stops working.
Spool guide sleeve: fixed the position of the reversing spool to
ensure its accurate movement during the working process, and with
the hydraulic control valve housing to form a sealing structure.
Hydraulic control valve shell: is the shell of the hydraulic
control valve, and there are multiple oil holes and connecting
ports inside, so that the hydraulic oil flows in the valve to
achieve the control of the hydraulic system.
[Two, the working principle of hydraulic control valve] :
Hydraulic control valve according to the flow direction and
pressure of hydraulic oil to achieve the control and regulation of
the hydraulic system, its working principle is as follows:
Oil supply stage:
a. The hydraulic pump draws the hydraulic oil from the tank and
transmits it to the hydraulic control valve through the hydraulic
pipeline.
b. The reversing spool of the hydraulic control valve adjusts the
channel of the hydraulic oil according to the operator's operation,
so that it enters the hydraulic rotary motor or other hydraulic
actuators.
Control stage:
a. Hydraulic control valve according to the flow direction and
pressure of hydraulic oil, to achieve the control of hydraulic
rotary motor and other hydraulic actuators.
b. The spool guide sleeve and spring in the hydraulic control valve
guide and control the spool movement, ensure the smooth flow of
hydraulic oil, and achieve the stable work of the hydraulic system.
Oil return stage:
a. After the hydraulic rotary motor and other hydraulic actuator
work, the hydraulic oil returns to the hydraulic control valve.
b. The reversing spool of the hydraulic control valve adjusts the
channel of the hydraulic oil according to the flow direction of the
return oil, so that it flows back to the tank and completes a
working cycle of the hydraulic system.
With its precise internal structure and efficient working
principle, the excavator hydraulic control valve realizes the
precise control and stable adjustment of the excavator hydraulic
system. Its flexibility and reliability provide a strong guarantee
for the efficient operation and safe operation of the excavator.
During the operation of the excavator, ensure the normal operation
of the hydraulic control valve to ensure the smooth operation of
the excavator and extend the life of the equipment.
Product operation manual
Thank you for choosing our excavator hydraulic control valve products! In order to ensure that you can correctly operate the hydraulic control valve during use and ensure the efficient operation of the hydraulic system, we have prepared this operation manual for you. Please read this manual carefully before use, and perform operation and maintenance according to the guidance.
1. Hydraulic control valve overview
The excavator hydraulic control valve is the key component of the excavator hydraulic system, which is responsible for controlling the hydraulic flow direction and pressure, adjusting the working state of the hydraulic system, so as to achieve the precise control of various actions of the excavator.
2. Safety precautions
Before operating a hydraulic control valve, be sure to follow the following safety precautions:
Make sure the excavator is in a safe and stable working condition
and stop the engine.
When inspecting and maintaining the hydraulic control valve, close
the main valve of the hydraulic system and ensure that the
hydraulic pressure has been released.
When operating the hydraulic control valve, do not touch the
hydraulic valve or its nearby moving parts with your hands to avoid
accidental injury.
When operating hydraulic control valves, focus on the job and avoid
distraction or fatigue.
3. Operation method of hydraulic control valve
Before starting the excavator, ensure that the following steps have been completed:
Turn on the main power supply of the excavator and confirm that the
hydraulic oil level is within the normal range.
Check the hydraulic oil temperature to ensure that it is within the
normal operating temperature range (usually -20°C to +80°C).
Start the engine and let it warm for a period of time until the
hydraulic oil temperature rises to the normal working range.
Operating hydraulic control valve:
According to the actual work requirements of the excavator, the
control rod or button on the hydraulic control valve is operated to
control the hydraulic flow direction and pressure.
In the operation process, pay attention to the working state of the
hydraulic system, such as hydraulic pressure, flow and other
parameters, to ensure that it operates within the normal range.
If you find that the hydraulic control valve is abnormal or the
hydraulic system has a problem, please stop using immediately, and
check and repair.
4. Maintenance method of hydraulic control valve
Regular maintenance of the hydraulic control valve can ensure its normal operation and extend its service life. Here are some suggested maintenance methods:
Check the seals and connectors of the hydraulic control valve
regularly, and replace them in time if they are damaged.
Clean the hydraulic control valve regularly to avoid sediment and
debris entering the valve body, affecting the flexibility of the
valve.
Pay attention to the cleaning and replacement of hydraulic oil to
ensure that the hydraulic oil in the hydraulic system meets the
specified quality standards.
Check and adjust the hydraulic control valve regularly to ensure
that it operates in normal working condition.
Thank you for reading our Excavator Hydraulic control Valve
operation manual. If you encounter any problems in the process of
use, please contact us in time, we will be happy to provide you
with technical support and service.
Wish your excavator work smoothly, safely and efficiently!
