Advantages Compared with mechanical transmission and electric transmission, hydraulic transmission has the following advantages: 1. Various components of hydraulic transmission can be arranged conveniently and flexibly according to needs. 2, light weight, small size, small movement inertia, fast response. 3, easy manipulation and control, enabling a wide range of stepless speed regulation (speed range up to 2000: 1). 4, can automatically overload protection. 5, the general use of mineral oil as a working medium, the relative movement surface can be self-lubricating, long service life; 6, it is easy to achieve linear motion / 7, it is easy to automate the machine, when combined with electro-hydraulic control, not only to achieve more High degree of automatic control process, but also to achieve remote control. Disadvantages Of course, there are some shortcomings of hydraulic transmission: 1, due to the fluid flow resistance and leakage greater efficiency. If handled improperly, leaks not only contaminate the site, but may also cause fire and explosion accidents. 2, due to work performance vulnerable to temperature changes, it is not suitable for high or low temperature conditions. 3, hydraulic valve components require higher precision, and therefore more expensive. 4, due to the leakage of liquid media and compressibility, can not be strict transmission ratio. 5, hydraulic drive failure is not easy to find the cause; use and maintenance requirements have a higher level of technology.
