Against the backdrop of the rapid development of the wind power industry, the demand for hydraulic systems in wind power generation equipment continues to increase, especially in key links such as blade adjustment and pitch control of wind turbines. The performance of hydraulic valves is directly related to the stability and operating efficiency of the […]

In the hydraulic system, the motor is the “heart” of the hydraulic pump. Its selection and matching directly affect the system performance. Asynchronous, servo, and variable frequency motors are suitable for different working conditions. The following are their selection points, efficiency optimization, and matching principles. 1. Asynchronous motor: An economical and practical conventional choice (1)

The iron core is an important and key component of the hydraulic oil pump motor. When the iron core is loose, there will always be some punching sheets or the end plates that press the iron core like tuning forks that vibrate under the action of electromagnetic force, making such noises. 1. Why does the

Core technology comparison: efficiency, cost and environmental protection 1. Electric drive: a new force in the energy revolution Advantages: (1) High efficiency and energy saving: The energy conversion efficiency of the motor can reach more than 90%, while the efficiency of the hydraulic system is usually only 60%-70% due to losses such as friction and

A hydraulic cylinder is a device that uses pressure to work. It needs to be used together with the tools it is equipped with. It can be used for lifting, bending, squeezing, stretching, punching and many other operations. Because of its versatility, it has a wide range of uses. However, if you don’t pay attention

As the most common and easiest to understand hydraulic valve in the hydraulic industry, the hydraulic check valve is widely used in hydraulic systems and occupies a vital position. It is a mature component in hydraulic systems. However, even so, it still has some problems in certain specific application scenarios, especially in the application of

Servo drives, also called “servo controllers” or “servo amplifiers”, are control devices used to control servo motors. They work similarly to frequency converters acting on ordinary AC motors and are an important part of servo systems, mainly used in high-precision positioning systems. Usually, servo motors are controlled in three ways: position, speed, and torque, to

Various forms of oil pipes and their accessories are important components of the hydraulic system. According to statistics, about 50% to 60% of hydraulic system failures are caused by oil pipes and their accessories not meeting the requirements. Therefore, the oil pipes must be carefully inspected and cleaned before installation, and attention must be paid

1. Cooler is corroded The main causes of corrosion are materials, environment (water quality, gas) and electrochemical reaction. Selecting corrosion-resistant materials is an important measure to prevent corrosion. For example, the fixed hole plate, the moving hole plate and the cooling copper pipe mouth often have serious corrosion. The solution is to improve the cooling
