The characteristics of hydraulic rotation
The disadvantages of hydraulic drive Oil resources are limited and combustible. There is no guarantee of strict transmission ratios. It is easy to pollute the environment. The cost of hydraulic drive system is high Ask for a separate source of energy. Troubleshooting is not easy to check.
One. Hydraulic drive: the transmission of power through liquid pressure to the liquid Work principle characteristics: A fluid drive with certain pressure; The transmission process goes through two energy transformations; The transmission must be carried out in a sealed container, and the volume should change The advantages of hydraulic drive Power is larger than large It can be used for stepless speed adjustment Automate easily Steady, long life Easy to implement overload protection 6. Be arranged flexibly
A complete, functioning hydraulic system should consist of five main parts: Power component: hydraulic pump, the function is to supply hydraulic system pressure oil, convert mechanical energy into pressure energy. Actuator: hydraulic cylinder, hydraulic motor, its function is hydraulic energy can be converted into mechanical energy. The hydraulic cylinder output force and the speed, the driving load is linear motion; The hydraulic motor output torque and rotational speed, and the load is rotated. 3. Control elements: control valve, its function is to the system to control the pressure, flow rate and flow direction, to ensure that the actuators to achieve the required output force (or torque), speed and direction. Such as relief valve, throttle valve, reversing valve, etc. Supporting components: auxiliary equipment needed to ensure proper functioning of the system, such as fuel tanks, oil filters, and tubing. Working medium: hydraulic oil
