TM85302 24V Multiple pilot proportional valve sany zoomlion
concrete pump truck parts
Product Description/Features:
First, the basic structure and working principle of pilot
proportional valve
The pilot proportional valve comprises a spool, a spool guide
sleeve, a proportional electromagnet, a permanent magnet, a flow
regulating potentiometer, a pressure regulating potentiometer, etc.
When it is in the liquid control center state, the pilot
proportional valve is closed, and the pressure in the control oil
circuit does not change, and the oil cannot pass through, so as to
maintain the stability of the oil circuit.
When the electromagnet is energized, according to the action of the
proportional electromagnet and the permanent magnet, the valve core
is shifted to achieve the purpose of adjusting the pressure and
flow of the liquid path. That is, by adjusting the flow and
pressure in the control liquid path, the precise control and
adjustment of the hydraulic system can be achieved.
Second, the role of pilot proportional valve in the hydraulic
system
The pilot proportional valve plays an important role in the
hydraulic system. Common applications are as follows:
1. Control the speed and stroke of the hydraulic cylinder: the
pilot proportional valve can adjust the flow rate and pressure of
the liquid, which is used to control the speed and stroke of the
hydraulic cylinder to achieve a more accurate control effect.
2. Adjust the pressure of the hydraulic system: the pilot
proportional valve can achieve accurate control and adjustment of
the hydraulic system by adjusting the pressure in the hydraulic
system.
3. Change the flow rate of the hydraulic system: the pilot
proportional valve can adjust the flow rate in the control liquid
path to meet the needs of different working conditions and improve
the efficiency of the system.
4. Maintain the stability of the system: the pilot proportional
valve can maintain the stability of the hydraulic system, prevent
fluctuations and pressure instability in the system, and improve
the safety and reliability of the system.
Third, the advantages and disadvantages of pilot proportional valve
1. Advantages: The pilot proportional valve can realize the
accurate adjustment and control of the hydraulic system, with fast
response speed, high control accuracy, wide adjustment range, good
reliability and other advantages.
2. Disadvantages: The main disadvantage of the pilot proportional
valve is that the installation and maintenance is relatively
complex, and requires professional operation and maintenance.
To sum up, the pilot proportional valve is a commonly used
component in the hydraulic system, and its role is mainly to
achieve accurate control and regulation of the hydraulic system by
adjusting the flow and pressure in the control liquid path. At the
same time, the pilot proportional valve also has the advantages of
fast response speed, high control accuracy, wide adjustment range,
good reliability, etc., but its installation and maintenance is
relatively complex, requiring professional personnel to operate and
maintain.
