What are the advantages and disadvantages of hydraulic tools

1. Generally, mineral oil is used as the working medium, the relative moving surface can be lubricated by itself, and the service life is long.
2. Light weight, small size, small movement inertia and fast reaction speed.
3. Various components of hydraulic transmission can be conveniently and flexibly arranged according to needs.
4. Overload protection can be realized automatically.
5. Convenient operation and control can realize stepless speed regulation in a wide range (speed regulation range up to 2000:1).
6. It is easy to realize linear motion.
7. It is easy to realize the automation of the machine. When the electro-hydraulic joint control is adopted, not only a higher degree of automatic control process can be realized, but also remote control can be realized

① There is a leak. The hydraulic pressure of the hydraulic system is high, and the hydraulic oil is easy to leak through the seal or gap, causing the consumption of hydraulic medium and causing environmental pollution.
②Low transmission efficiency In the process of energy transmission, hydraulic transmission often has more energy loss (pressure loss and flow loss, etc.), which makes the transmission efficiency low
③Inaccurate transmission ratio Due to factors such as the compressibility of the transmission medium, leakage and the elastic deformation of the pipeline, the hydraulic system cannot strictly guarantee the constant ratio transmission.
④ Sensitive to temperature. The viscosity of oil changes with temperature. The change in viscosity causes changes in flow, leakage and resistance, which easily cause unstable movement of the working mechanism.
⑤High manufacturing cost In order to reduce leakage, the manufacturing precision of hydraulic components is required to be high, thereby increasing the manufacturing cost
