As a key actuator in the hydraulic system, the hydraulic cylinder carries important mechanical movement functions. The long-term use of the hydraulic cylinder will experience environmental conditions such as high pressure, high temperature, and frequent motion loads. Therefore, wear is an important factor affecting its performance and service life. Wear not only leads to a decrease in system efficiency, but may also cause more serious problems such as leakage and jamming. In order to ensure the normal operation of the hydraulic cylinder and extend its service life, it is essential to prevent wear.
The following are effective measures to prevent wear of hydraulic cylinders:

1. Optimize the selection and management of hydraulic oil
Choose the right hydraulic oil
The impact of oil quality: The quality of hydraulic oil is directly related to the degree of wear of the cylinder. Impurities, moisture, bubbles and too low lubricity in the oil will aggravate the wear of the cylinder.
Solution:
Use high-quality hydraulic oil that meets the system requirements to ensure that the oil has good lubricity, oxidation resistance and corrosion resistance.
Select the appropriate oil according to the working temperature and pressure and other working conditions to avoid using expired, contaminated or unqualified hydraulic oil.
Keep the hydraulic oil clean
The impact of contaminants on wear: Impurities such as dust, metal chips or moisture contained in the hydraulic oil are one of the main causes of cylinder wear. These contaminants will increase the friction of the piston, piston rod and cylinder under high-pressure and high-speed working conditions, causing local wear.
Solution:
Equip with oil filters and replace the filters regularly to prevent impurities from entering the system.
Check the quality of the hydraulic oil regularly, especially the moisture, acidity and particulate matter content, and clean or replace the oil in time.
Maintain the proper temperature of the oil
The effect of temperature on cylinder wear: Too high or too low hydraulic oil temperature may affect the lubrication effect, increase friction and cause wear. Too high temperature will cause the oil viscosity to decrease and reduce lubrication performance; too low temperature may cause the oil viscosity to increase and affect fluidity.
Solution:
Use temperature control equipment (such as oil cooler) to keep the oil temperature within the appropriate range and ensure that the viscosity and fluidity of the oil are within the normal range.
Check the temperature of the hydraulic oil regularly and adjust the oil viscosity and temperature control system according to the actual working conditions.

2. Improve the design of hydraulic system and working environment
Reasonably design the hydraulic system
The impact of system design on wear: The design of the hydraulic system should minimize pressure fluctuations, reduce the curvature and length of the pipeline, reduce the resistance of the system, etc., which will help reduce the impact of hydraulic oil on the cylinder and reduce wear.
Solution:
Reasonably design the hydraulic system to ensure that the pipeline layout is simple and smooth, and reduce the friction resistance between the pipeline and the components.
Use appropriate pressure settings to avoid excessive loads caused by high pressure causing wear on the cylinder.
Reduce the impact load in the system
The impact of impact load on wear: Frequent impacts or load changes in the system (such as impacts during start and stop) will increase the load on the cylinder, thereby accelerating wear.
Solution:
Use buffer devices (such as buffer valves, buffer blocks, etc.) to slow down the impact in the hydraulic system and protect the cylinder and its components.
Optimize the start and stop process of the system to avoid sharp pressure fluctuations.
Avoid overloading the cylinder
The impact of overload on wear: When the cylinder works under overload, it will generate excessive pressure and temperature, aggravate wear, and may cause damage to the seals inside the cylinder.
Solution:
Set reasonable load and working parameters to avoid overloading the cylinder.
Equip with overload protection devices, such as pressure control valves, to avoid excessive system pressure.

3. Regular maintenance and inspection of cylinder components
Regularly check the inside of the cylinder
Check the impact of cylinder wear: Regularly check the internal parts of the cylinder, such as pistons, piston rods, cylinder bodies, etc., to promptly detect wear, scratches and other problems to prevent further wear.
Solution:
Disassemble the cylinder regularly, check the surface condition of the piston rod and cylinder body, and check for scratches, rust or wear.
For minor wear or scratches, repair; for severely worn parts, replace them in time.
Check the status of the seals
The impact of seals on wear: The seals of the cylinder not only prevent oil leakage, but also prevent external contaminants from entering the cylinder. Aging or damage to the seals will cause system leakage or contaminants to invade, further accelerating the wear of the cylinder.
Solution:
Regularly check the seals of the cylinder to ensure their integrity and elasticity, and replace aging or damaged seals in time.
Use wear-resistant and high-temperature resistant sealing materials to improve sealing performance and extend the service life of seals.

4. Reasonable operation and use
Avoid frequent starting and stopping
The impact of frequent starting on wear: When the hydraulic system is frequently started and stopped, it will bring a large impact load to the cylinder, causing unnecessary friction between the piston, piston rod and cylinder body, and increasing wear.
Solution:
Avoid frequent start-stop operations during use to maintain a stable working state.
Use flow control devices or variable frequency drives to optimize the working rhythm of the system.
Maintain appropriate load and speed
The impact of load and speed on wear: Excessive load and speed will aggravate the wear of the cylinder, especially when overloaded, the cylinder is prone to excessive friction.
Solution:
Control the load and speed of the hydraulic system to ensure that it operates within the design range and avoid overload or overspeed operation.
Use a load detection device to monitor the working status of the system in real time to avoid the cylinder from working under high load for a long time.

5. Summary
The wear of hydraulic cylinders is an inevitable problem in hydraulic systems, but by taking reasonable oil management, system optimization, regular inspection, fine operation and other measures, the wear of cylinders can be effectively reduced and the efficiency and service life of hydraulic systems can be improved. Regular maintenance and monitoring of the working condition of the cylinders, and timely detection and resolution of potential problems are the key to ensuring the long-term stable operation of the hydraulic system.
