What are the advantages and disadvantages of hydraulic？

Advantages of hydraulic:

1. Various components of hydraulic transmission can be conveniently and flexibly arranged according to needs.

2. Light weight, small volume, small motion inertia and fast reaction speed.

3. It is easy to operate and control, and can realize a wide range of stepless speed regulation (speed regulation range up to 2000:1).

4. Overload protection can be realized automatically.

5. Mineral oil is generally used as the working medium. The relative moving surface can be lubricated by itself and has a long service life.

6. It is easy to realize linear motion.

7. It is easy to realize the automation of the machine. When electro-hydraulic combined control is adopted, not only a higher degree of automatic control process can be realized, but also remote control can be realized.

Disadvantages of hydraulic:

1. Due to the large resistance and leakage of fluid flow, the efficiency is low. If not handled properly, the leakage will not only pollute the site, but also cause fire and explosion accidents.

2. Because the working performance is easily affected by temperature change, it is not suitable to work at very high or low temperature.

3. The manufacturing accuracy of hydraulic components is high, so the price is expensive.

4. Due to the leakage and compressibility of liquid medium, strict transmission ratio can not be obtained.

5. It is difficult to find out the cause when the hydraulic transmission fails; High technical level is required for use and maintenance.
