As we all know, hydraulic power machinery is a machine that uses liquid as the working medium to transfer energy to realize various processes. In addition to forging and forming, hydraulic power machinery can also be used for straightening, pressing, packing, pressing blocks and pressing plates. But do you really understand hydraulic power machinery? Let me explain to you the advantages and limitations of hydraulic power machinery.

Hydraulic cylinder is the actuator in the hydraulic transmission system, which is an energy conversion device that converts hydraulic energy into mechanical energy. The hydraulic motor realizes the continuous rotary motion, while the hydraulic cylinder realizes the reciprocating motion. There are three types of hydraulic cylinders: piston cylinder, plunger cylinder and swing cylinder. Piston cylinder and plunger cylinder realize reciprocating linear motion, output speed and thrust, and swing cylinder realizes reciprocating swing, output angular velocity (rotation speed) and torque. In addition to being used singly, hydraulic cylinders can also be used in combination of two or more or in combination with other mechanisms. to perform special functions. The hydraulic cylinder is simple in structure and reliable in operation, and has been widely used in the hydraulic system of machine tools.

The year 2022 is a very important year for the development of the Party and the country, and the year when the 20th National Congress of the Party will be held. What kind of new development prospect will China's "two sessions" unfold to the world? On the 5th, the government work report submitted to the Fifth Session of the 13th National People's Congress for deliberation put forward a series of new goals and new arrangements, sending a new signal of China's economic and social development.

Hydraulic shocks in hydraulic pump stations are unavoidable. Hydraulic shock refers to a sudden change in pressure caused by a sudden change in the motion state of hydraulic oil in a hydraulic pump station. Hydraulic shocks can damage some hydraulic components in the hydraulic power pack. The reason is that when the hydraulic shock occurs, the local pressure may instantly increase several times or dozens of times. Therefore, the hydraulic shock is suppressed and the maximum possible hydraulic shock is estimated.

After the hydraulic pump is installed, it must be filled with clean hydraulic oil through the oil drain port on the tie shell before starting for the first time, otherwise it cannot be started. After installing the hydraulic pump and motor and connecting the system correctly, inject clean oil into the pump or motor, remove the upper drain pipe, and tighten the joint after seeing the oil flow out. The starting of the hydraulic pump has the following contraindications: 1. Rotate the coupling by hand to check the state of the pump shaft. It is forbidden to have uneven force during rotation, loose installation, and two couplings with different shafts.

First, the definition of hydraulic system The hydraulic system is mainly divided into the transmission system and the control system. A complete hydraulic system requires five parts, including power components, actuators, control components, auxiliary components and hydraulic oil. The hydraulic system we often say is mainly used to transmit power and movement. Transport hydraulic oil, etc.
