As a transmission technology, hydraulic systems have outstanding advantages:
1. It can generate a lot of force and is easy to control.
2. Capable of stepless speed regulation over a wide range.
3. It is easy to prevent overload and has high safety.
4. The size is small and the output force is large, and the installation position can be freely selected.
5. The adjustment of output force is simple and accurate, and can be remotely controlled.
Hydraulic technology also has some drawbacks, such as the following issues that must be considered:
1) Tubing technology;
2) The invasion of pollutants and dust;
3) Fault diagnosis;
4) The temperature change of hydraulic oil;
5) Oil leakage.
The mechanical performance of fully hydraulic transmission mainly depends on the performance of the hydraulic system, including the quality of the components used and the appropriateness of the basic circuit. The performance of the system should not only meet the functional requirements, but also be evaluated in terms of the efficiency, power utilization, speed range and fine tuning characteristics of the hydraulic system, vibration and noise, as well as the convenience and reliability of system installation and debugging.
