1.Because of the large resistance and leakage of fluid flow, the efficiency is low. If not handled properly, the leakage not only pollute the site, but also may cause fire and explosion accidents.
2.Because the performance of the work is easy to be affected by the temperature change, it is not suitable to work at high or low temperature.
3.High accuracy of hydraulic components, such as the hydraulic pressure valve, so the price is relatively expensive.
4.Due to the leakage of the liquid medium and the compressibility, it can not get the strict transmission ratio.
5.Hydraulic transmission is not easy to find out the reasons for failure; require a higher level of technology for operation and maintenance.
