What are the advantages and disadvantages of hydraulic transmission? Dalan Hydraulics will analyze it with you!
The advantages are as follows:
1. From the structure point of view, the output power per unit weight and the output power per unit size are the best among the four types of transmission modes, and there is a large moment inertia ratio.
2. In the case of transmitting the same power, the hydraulic transmission device is small in size, light in weight, small in inertia, compact in structure and flexible in layout.
3. From the perspective of working performance, the speed, torque and power can be adjusted steplessly, the action response is fast, the speed can be changed quickly and the speed is changed, the speed regulation range is wide, the motion is fast, the control and adjustment are relatively simple, and the operation is convenient. It is labor-saving, easy to cooperate with electrical control, and connected to the CPU (computer) for easy automation.
4. From the perspective of use and maintenance, the self-lubricating property of hydraulic components is good, and it is easy to realize overload protection and pressure keeping, which is safe and reliable; components are easy to realize serialization, standardization and generalization.
5. From the perspective of safety performance, all equipment using hydraulic technology has good safety and reliability.
6. From the perspective of economy, the plasticity and variability of hydraulic technology are very strong, which can increase the flexibility of flexible production, and easy to change and adjust the production process. The hydraulic components are relatively low in manufacturing cost and relatively adaptable. .
7. The combination of hydraulic technology and new technologies such as microcomputer control constitutes the “machine-electric-liquid-light” integration, which has become the trend of world development and is easy to realize digitalization.
The disadvantages are as follows:
1. The hydraulic transmission is inevitably leaked due to the relative motion surface. At the same time, the oil is not absolutely incompressible. In addition, the hydraulic transmission cannot obtain a strict transmission ratio due to the elastic deformation of the oil pipe. Therefore, it cannot be used for machine tools such as threaded gears. In the inline drive chain.
2. There are loss along the loss, local loss and leakage during the flow of oil. The transmission efficiency is low and it is not suitable for long-distance transmission.
3. Under high temperature and low temperature conditions, there are certain difficulties in using hydraulic transmission.
4, in order to prevent oil leakage and to meet certain performance requirements, hydraulic components manufacturing accuracy requirements are high, which brings certain difficulties to the use and maintenance.
5, the failure is not easy to check, especially the unit where hydraulic technology is not popular, this contradiction often hinders the further promotion and application of hydraulic technology. Hydraulic equipment maintenance relies on experience and trains hydraulic technicians for a longer period of time.
