As we all know, hydraulic power machinery is a machine that uses liquid as the working medium to transfer energy to realize various processes. In addition to forging and forming, hydraulic power machinery can also be used for straightening, pressing, packing, pressing blocks and pressing plates. But do you really understand hydraulic power machinery? Let me explain to you the advantages and limitations of hydraulic power machinery.

As a transmission technology, hydraulic power machinery has its outstanding advantages:

One is that it can generate a lot of force and is easy to control. High pressure hydraulic oil can be easily obtained with a pump, and a large force can be generated after the pressure oil is fed into the hydraulic cylinder. The reason why hydraulic technology is used in presses, die-casting machines, and injection molding machines is that such large forces can be easily obtained.

The second is stepless speed regulation in a wide range. The flow rate supplied to the hydraulic motor or hydraulic cylinder can be adjusted steplessly with the control valve, and the speed of its rotation or linear motion can be controlled at will.

Third, the size is small and the output is large, and the installation position can be freely selected. No matter where the control valve and actuator are installed, it is enough to connect the pipe or hose, so there is a lot of freedom in design. This comes into play in industrial vehicles, machine tools, etc., which must reduce weight, increase power density, and make the most of space.

Fourth, the adjustment of the output force is simple and accurate, and it can be controlled remotely. If a pressure control valve is used to control the pressure, it is easy to control the output force of the actuator. If a proportional solenoid valve is used, an electrical signal can also be used to control the pressure, enabling remote control.

Hydraulic power machinery also has its own shortcomings:

One is piping technology. The piping technology determines that the working pressure of the system and the arrangement of components must follow certain rules, and the damage to the piping components will lead to the loss of system function and bring other dangers.

The second is the intrusion of pollutants and dust; system pollution will lead to unstable system operation and sharp decline in component life.

Third, it is difficult to diagnose faults.

The fourth is the temperature change of hydraulic oil. Changes in oil viscosity caused by changes in oil temperature will reduce the efficiency of the system and increase the aging of system components.

To sum up, this is the whole content of the advantages and limitations of hydraulic power machinery. In hydraulic power machinery, we must comprehensively use hydraulics, pneumatics, and electricity to make it more fully play its due role. At the same time, we must also understand the limiting factors of hydraulic power machinery itself, and add more in future applications. guard against.
