                                              一個完整的液壓機液壓系統由五個部分組成,即動力元件、執行元件、控制元件、輔助元件(附件)和液壓油。液壓傳動系統以傳遞動力和運動為主要功能。液壓系統的作用為通過改變壓強增大作用力。

                                               

                                              液壓系統優點

                                              1、體積小和重量輕;

                                              2、剛度大、精度高、響應快;

                                              3、驅動力大,適合重載直接驅動;

                                              4、調速范圍寬,速度控制方式多樣;

                                              5、自潤滑、自冷卻和長壽命;

                                              6、易于實現安全保護。

                                               

                                              液壓系統缺點

                                              1、抗工作液污染能力差;

                                              2、對溫度變化敏感;

                                              3、存在泄漏隱患;

                                              4、制造難,成本高;

                                              5、不適于遠距離傳輸且需液壓能源。

                                               

                                               

                                              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.
