Hydraulic technique is based on fluid mechanics as the basic and gradually developed skills, it develops late, but it is a new technique that develops rapidly. It is important to apply the pressure of the liquid to the transmission of force and torque, the so-called hydraulic transmission.
At the end of the last century, it was first used in the transmission of machinery and machine tools. With the increasing development of this technique, its utilization scope in engineering skills has gradually expanded. It was used in drilling equipment from the 1990 s to the late 1990 s. It presented a "full hydraulic drilling rig". Hydraulic skills have been fully used in drilling equipment and have now reached a relatively mature and perfect field.
The working principle of hydraulic transmission system The hydraulic transmission system is a set of liquid flow cycle system composed of various hydraulic components. It first changes the mechanical energy input by the electric idea into the pressure energy of the liquid, adjusts and controls the liquid flow of each hydraulic component to transmit pressure and working signals, and then uses the appropriate performance mechanism to change the hydraulic energy to change the mechanical energy to drive the working mechanism, Realize the various actions that you beg.
Advantages of hydraulic transmission
(1) It is convenient to realize stepless speed regulation in a larger scope.
2, hydraulic components are easy to achieve body serialization, scale and generalization.
3, with oil as the working medium, with self-lubricating performance and vibration absorption ability.
4. The transmission is balanced and uniform, easy to realize active overload maintenance and reduce accidents.
5. The output power per unit mass is large, and it is easy to obtain large forces and moments. Due to the light weight, the inertia is small and the action is fast.
6. Centralized operation, simple and labor-saving.
Disadvantages of hydraulic transmission
1, the adjustment of the hydraulic system, protection and maintenance and review, determine and eliminate the fault need higher degree of skill.
2, the oil into the air, prone to vibration, noise and crawling phenomenon.
3, the quality of the oil, filtration, cooling and leak-proof sealing and hydraulic components processing quality (size, precision, finish, etc.) request higher.
4. When the temperature changes, the activity characteristics change due to the change of oil viscosity.
