Hydraulic Transmission

The advantages and disadvantages of hydraulic transmission are analyzed

What are the advantages and disadvantages of hydraulic transmission? Hydraulic exhibition will analyze with you and have a look!

The advantages are as follows:

1. In terms of structure, the output power per unit weight and output power per unit size are good in the four types of transmission modes, with a large torque inertia ratio.

2. Under the condition of transmitting the same power, the hydraulic transmission device has the advantages of small volume, light weight, small inertia, compact structure and flexible layout.

3. In terms of working performance, speed, torque and power can be adjusted steplessly, with fast action response, rapid commutation and speed change, wide speed regulation range, good action rapidity, simple control and adjustment, convenient and labor-saving operation, easy to cooperate with electrical control and connect with CPU (computer), so as to realize automation.

4. From the perspective of use and maintenance, the hydraulic components have good self lubrication, easy to realize overload protection and pressure holding, safe and reliable; Components are easy to realize serialization, standardization and generalization.

5. In terms 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 it is easy to change and adjust the production procedure. The manufacturing cost of hydraulic components is relatively low and the adaptability is relatively strong.

7. The combination of new technologies such as hydraulic ease and microcomputer control constitutes the "mechanical electrical hydraulic optical" integration, which has become the trend of world development and is convenient to realize digitization.

The disadvantages of the hydraulic system are as follows:

1. Due to the relative moving surface of hydraulic transmission, there is inevitable leakage. At the same time, the oil is not incompressible. Coupled with the elastic deformation of oil pipe, hydraulic transmission can not obtain strict transmission ratio, so it can not be used in the inline transmission chain of machine tools such as machining threaded gears.

2. There are edge loss, local loss and leakage loss in the process of oil flow, and the transmission efficiency is low, which is not suitable for long-distance transmission.

3. Under high and low temperature conditions, it is difficult to adopt hydraulic transmission.

4. In order to prevent oil leakage and meet some performance requirements, the manufacturing accuracy of hydraulic components is required to be high, which brings some difficulties to use and maintenance.

5. Failure is not easy to check, especially in units where hydraulic technology is not very popular, this contradiction often hinders the further popularization and application of hydraulic technology. The maintenance of hydraulic equipment depends on experience, and it takes a long time to train hydraulic technicians
