Suitable for SK60SR SK75SR excavator hydraulic pump YT35V00005F1 proportional solenoid valve

    Advances in electro-hydraulic proportional valves and other special devices have made the electrical control of various systems such as gear, steering, braking and working devices of engineering vehicles a reality. General required displacement
The output mechanism can be used similar to Figure 1 proportional servo control manual multi-way valve driver to complete, electrical operation has the advantages of fast response, flexible wiring, can achieve integrated control and easy interface with the computer, etc. Modern construction machinery hydraulic valve has been more and more electronically controlled pilot control electro-hydraulic proportional valve (or electro-hydraulic switch valve) instead of manual direct operation or hydraulic pilot control multi-way valve. Another significant advantage of using electro-hydraulic proportional valves (or electro-hydraulic on-off valves) is that the number of operating handles can be greatly reduced on engineering vehicles, which makes the cab layout simple, can effectively reduce the complexity of operation, and has important practical significance for improving the quality and efficiency of work. Figure 2 shows the TECNORD JMF control stick. The multi-piece electro-hydraulic proportional valve and on-off valve shown in Figure 2 can be effectively controlled by using a single rocker. The rocker can realize proportional control or switch control in both X axis and Y axis direction, and the application is very convenient.
With the rapid development of digital wireless communication technology, there has been a stable performance, reliable work, suitable for wireless remote control system of construction machinery, remote control receiving device on mobile machinery
The received radio signal can be converted into the control electro-hydraulic proportional valve proportional signal and control electro-hydraulic switch valve switch signal, as well as the corresponding signal control of other devices, so that the original manual operation of each component can accept the remote control electrical signal instruction and carry out the corresponding action, at this time the construction machinery has actually become a remote control construction machinery.
Wireless remote control transmitting and receiving system has been successfully applied to a variety of construction machinery remote control transformation. From a security point of view, it transmits each digital data instruction has a special set
System address code, which is used only once by the manufacturer. Each receiver responds only to transmitted signals with the same address code, and other wireless signals with the same frequency will affect the receiving device. With other safety measures adopted, the reliability of the system is fully guaranteed. A variety of mobile machinery, such as loader, rock drill, concrete pump truck, aerial work truck and bridge repair truck, have been successfully transformed by remote control. The industrial remote control device and the electro-hydraulic proportional valve complement each other, the electro-hydraulic proportional valve provides a feasible interface for the forced control of construction machinery, and the remote control device enables the electro-hydraulic proportional valve to play a greater role.
