All engineering diggers should be aware of one thing, how important and vital is the hydraulic system as a power component for small excavators? Why do you say that? Then listen to the editor tell you:
The hydraulic system of a small excavator is an energy conversion device. It first converts mechanical energy into hydraulic energy for easy transportation, and then converts hydraulic energy into mechanical energy to do work. Some mechanical transmissions, but now hydraulic systems are generally used for transmission. This is because The hydraulic system is not only small in size and light in weight, but also can output the same power as a larger mechanical transmission, that is to say, its weight per unit power is light, which makes the layout, connection and installation of the system very flexible, so it can constitute Complex systems that are difficult to construct by other means.
The hydraulic system of the small excavator drives the hydraulic cylinder and the motor through the engine to convert the mechanical energy into the pressure of the hydraulic oil, so the way it transmits the movement is more uniform and stable, and there will be no great vibration, and the oil itself has the ability to absorb vibration , which enables the machine to achieve quick start, brake and frequent reversing, and it can be infinitely adjustable in operation
The control operation of the hydraulic system is more convenient and labor-saving, and can realize automatic control and overload protection, especially when it is combined with electrical control and electronic control, it can easily realize automatic working cycle and automatic overload protection; finally, hydraulic components are easy to realize series Standardization, generalization, easy design, manufacture and popularization.
In summary, due to the advantages of small size, light weight, high power density, stable operation, strong controllability, and the ability to realize stepless speed regulation in a wide range, the hydraulic system mentioned above is expected to be widely used.
