1. What is an accumulator A hydraulic accumulator is a device that stores energy. In an accumulator, the stored energy is stored in the form of compressed gas, compressed springs, or lifted loads, applied to a relatively incompressible fluid. Accumulators are very useful in fluid power systems to store energy and eliminate pulses. They can […]

When a hydraulic cylinder fails to operate, first check the hydraulic oil level, pump operation status, and suction filter blockage (power source). Then verify control signals, solenoid valve energization/function, valve spool sticking, and pilot pressure (control system). Finally, inspect cylinder line blockage/leakage, internal seal failure, and mechanical binding in the load or mounting (actuator). 1.

In the industrial field, “rotary pumps” provide power for countless devices, driving everything from hemodialysis to 10,000-ton tankers. In fact, the gear pump is one of the most classic and widely used members of the rotary pump category!This article focuses on gear pumps to learn about this master of fluid control deep in industrial equipment.

Preventing hydraulic motor failures requires a combination of proper design, maintenance, and operating practices. Although hydraulic motors are similar to hydraulic pumps, they are unique in that they convert hydraulic energy (in the form of pressure and flow) into rotational energy (in the form of operating torque). Hydraulic motors are used to drive winches, wheels,

Although hydraulic hoses are often regarded as ordinary components, they have to withstand complex working conditions – a wide range of pressures, thousands of machine cycles, frequent pressure fluctuations, and large ranges of motion. Once a failure occurs, it may lead to high downtime costs, equipment damage, and even casualties. Therefore, scientific management of the

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
