  • Hydraulic transmission is a kind of transmission using pressure oil as working medium

    Pneumatic is the abbreviation of "pneumatic technology" or "pneumatic transmission and control". Pneumatic technology uses air compressor as the power source and compressed air as the working medium to perform energy transmission or signal transmission engineering technology. It is one of the important means to achieve various production control and automatic control. Hydraulic transmission is a type of fluid transmission. Its basic principle is to use pressure in a closed container.

  • Causes of cavitation in hydraulic cylinders and preventive measures

    Hydraulic equipment system There are some honeycomb holes in the inner wall of the cylinder of the hydraulic cylinder, the surface of the piston or the piston rod, which are all caused by cavitation. Cavitation will cause the mating surface of the cylinder barrel and piston rod to become rough, internal leakage will occur in the hydraulic cylinder, and the working speed will decrease. When cavitation and other forms of corrosion work together, it will accelerate the corrosion rate of the main parts of the hydraulic cylinder, which will seriously affect the construction machinery.

  • Common points of various types of hydraulic valves

    Natural gas pull-off valve hydraulic valve is the most commonly used system in industrial production. It is mainly used to control the flow direction of oil in the hydraulic system, and it can also effectively adjust the pressure and flow. There are three main types of hydraulic valves, namely pressure valves, directional valves and flow valves. For valves with the same shape, companies can choose different functions according to their different mechanisms. Although hydraulic

  • History of hydraulic development

    Hydraulic maintenanceHydraulic transmission and pneumatic transmission are called fluid transmission, which is an emerging technology developed based on the principle of hydrostatic pressure transmission proposed by Pascal in the 17th century. Water is used as a working medium in London, and it is applied to industrial machines in the form of hydraulic presses.

  • Briefly describe the principle of hydraulic transmission pressure of hydraulic cylinders

    The principle of the same hydraulic transmission pressure of the hydraulic equipment system, the larger the area under pressure, the greater the pressure, and the smaller the area, the smaller the pressure. There is also the principle of the task of leverage. Jack is the simplest lifting equipment with a small lifting height (less than 1m). It has two types: mechanical and hydraulic. There are two types of mechanical jacks: rack type and screw type.

  • Advantages of hydraulic cylinders

    After the metal workpiece of the hydraulic equipment system is rolled on the surface, the surface layer is strengthened and the ultimate strength and yield point are increased, and the workability, fatigue strength, wear resistance and corrosion resistance of the workpiece are significantly improved. After rolling, the hardness can be increased by 15-30%, and the wear resistance can be increased by 15%. Rolling can improve surface roughness from Ra6.3 to Ra2.4

  • Structure of natural gas pipeline ball valve

    The basic structure of high-pressure ball valves for natural gas pipelines: General ball valves for natural gas pipelines are mainly composed of valve body, ball body, valve seat, valve stem and transmission device. The main function of the ball valve is to connect and cut off the fluid in the pipeline. Compared with the globe valve, it has a much smaller switching stroke. As long as the ball is rotated 90 °, the function of opening and closing can be achieved. Let ’s introduce

  • How to avoid the heat of hydraulic station maintenance

    Hydraulic Maintenance Hydraulic Station Maintenance Techniques Solve the System Heating Problem: The system heating of the hydraulic station maintenance is the reflection of the rise in the temperature of the hydraulic oil. The reason is that the hydraulic oil has different flow rates during the flow process, which causes a certain amount of fluid inside. Internal friction, and at the same time there is friction between the liquid and the inner wall of the pipeline, causing the entire hydraulic temperature to rise. Many are due to hydraulics

  • The development process of hydraulic system

    Hydraulic equipment system In 1795, Joseph Braman (1749-1814) in the United Kingdom used water as a working medium in London to apply it to industry in the form of a hydraulic press, and the world's first hydraulic press was born. In 1905, the working medium was changed from oil to oil, and it was further improved. World War I (1
