作者:admin    来源:未知    发布时间:2020-08-18 21:01    浏览量:

一个完整的液压机液压系统由五个部分组成,即动力元件、执行元件、控制元件、辅助元件(附件)和液压油。液压传动系统以传递动力和运动为主要功能。液压系统的作用为通过改变压强增大作用力。

 

液压系统优点

1、体积小和重量轻;

2、刚度大、精度高、响应快;

3、驱动力大,适合重载直接驱动;

4、调速范围宽,速度控制方式多样;

5、自润滑、自冷却和长寿命;

6、易于实现安全保护。

 

液压系统缺点

1、抗工作液污染能力差;

2、对温度变化敏感;

3、存在泄漏隐患;

4、制造难,成本高;

5、不适于远距离传输且需液压能源。

 

 

A complete hydraulic system of hydraulic press is composed of five parts, namely, power components, executive components, control elements, auxiliary components (accessories) and hydraulic oil. The main function of hydraulic transmission system is to transfer power and movement. The function of the hydraulic system is to increase the force by changing the pressure.

Advantages of hydraulic system

1. Small size and light weight;

2. High rigidity, high precision and fast response;

3. Large driving force, suitable for heavy load direct drive;

4. Wide range of speed regulation and various speed control modes;

5. Self lubricating, self cooling and long life;

6. Easy to implement security protection.

Disadvantages of hydraulic system

1. The anti pollution ability of working fluid is poor;

2. It is sensitive to temperature change;

3. There are potential leakage hazards;

4. Difficult to manufacture and high cost;

5. It is not suitable for long distance transmission and needs hydraulic energy.
