Krav för användning av hydraulisk transmission för lyftplattformsutrustning
1. Hydraulic transmission uses liquid as the working medium, and leakage cannot be avoided in the relative movement of hydraulic components. Coupled with the compressibility of liquid, it is difficult to achieve a strict transmission ratio.
2. Liquid viscosity is closely related to temperature. When viscosity changes with temperature, it will directly affect leakage, pressure loss and flow through components. Therefore, the hydraulic system should not work at very high and very low temperatures.
3. The energy in the hydraulic system has to be converted twice, so the transmission efficiency is low. Operating reliability is currently not as good as electrical and mechanical drives.
4. The manufacturing precision of hydraulic components is high. The use and maintenance require certain professional knowledge and high technical level. The cause of the failure is difficult to determine.
In general, hydraulic transmission has many advantages, but its shortcomings cannot be ignored. In order to improve its competitiveness, hydraulic transmission technology has been developing continuously. With the support of modern technology and the scientific and technological achievements of related disciplines, the continuous development of hydraulic technology has gradually overcome its shortcomings, continuously improved its performance, and continued to expand its application fields. Hydraulic transmission technology will be more widely used.
