1. The definition and principle of hydraulic actuator

Hydraulic actuator is an institution that converts hydraulic energy to mechanical energy or other forms of energy. It consists of parts such as hydraulic cylinder and liquid cylinder, and the liquid uses the liquid to generate force and displacement under the pressure of the hydraulic cylinder or liquid cylinder. The hydraulic actuator is an execution mechanism that realizes mechanical movements in the hydraulic system. Its role is to transform the energy of the hydraulic system into force and displacement.

The principle of hydraulic actuator is based on the knowledge of fluid mechanics, using pressure transmission, flow control and leverage principle, so as to achieve the purpose of controlling mechanical movements. The hydraulic actuator to control the control of mechanical movement by adjusting the pressure and direction of the liquid.

2. Common types of hydraulic actuators

1. Hydraulic cylinder

Hydraulic cylinder is an important type of hydraulic actuator. It can convert hydraulic energy into mechanical energy or other forms of energy, and is widely used in industrial, machinery, agriculture and other fields.

2. Hydraulic motor

Hydraulic motor is a hydraulic actuator that converts liquids into mechanical energy. Its principle is to use liquid to promote the internal parts of the motor to drive the rotation of the motor.

3. Hydraulic vibrator

Hydraulic vibrator is a device that uses hydraulic pulses to inspire vibration sources. It realizes vibration by converting pneumatic arteries signals into liquid arterial signals and sent into vibration sources through the emissions tube.

Three, the application field of hydraulic actuator

Hydraulic actuators are widely used in many fields, such as machinery, industry, agriculture and aviation. In mechanical manufacturing, hydraulic actuters are often used in equipment such as hydraulic shear machines, hydraulic punching, hydraulic pressure machines. In industrial manufacturing, hydraulic actuators are often used in equipment such as machine tools, cranes, conveyors and other equipment. In agriculture, hydraulic actuators are often used in agricultural machinery such as tractors, harvesters, and irrigation equipment.

In short, a hydraulic actuator is an institution that converts hydraulic energy or other forms of energy. There are many types of hydraulic actuators, which are widely used in machinery, industry, agriculture, and aviation, and play an important role in modern industrial and agricultural production.
