In the hydraulic system, whether the oil pressure is stable is the key to the normal operation of the system. When the valves in the hydraulic system have poor sealing problems, it will cause the oil pressure to decrease and bring a series of abnormal problems to the hydraulic system. LindePolymer will discuss with you the causes of low oil pressure caused by poor valve sealing, the impact on the system and ways to solve the problem.

Reasons for poor valve sealing

Several reasons for poor valve sealing

  1. Aging or damage to the sealing ring: The sealing ring is a decisive component of the valve sealing effect. After long-term use or being affected by the external environment, the sealing ring may age, harden, crack, etc., resulting in a decrease in sealing effect.
  2. Wear of valve components: The piston, valve core and other components inside the valve will wear out during long-term operation. Excessive wear can also lead to poor sealing.
  3. Debris blockage: Impurities, sediments, etc. in the hydraulic system will accumulate on the contact surface of the valve seal, modifying the sealing effect.

The impact of poor valve sealing on the system

  1. Oil pressure drop: Poor valve sealing will cause oil leakage in the hydraulic system, thereby reducing the pressure and oil pressure inside the system and influencing the normal operation of the system.
  2. Inaccurate action: Low oil pressure will cause the valve to operate inaccurately and cannot be controlled as expected, which has a great impact on the accuracy and stability of the system.
  3. Reduced energy efficiency: Low oil pressure will reduce the working efficiency of the hydraulic system, increase energy consumption, and reduce the energy efficiency performance of the system.
  4. Shortened component life: Low oil pressure will cause components in the hydraulic system to bear loads beyond their own carrying capacity, accelerate component damage, and greatly shorten the service life of system equipment.

How to solve the problem of poor valve sealing

  1. Regularly check and replace sealing rings: Regularly check the valve sealing rings in the hydraulic system. Once aging, deformation or damage is found, try to replace them as soon as possible to ensure good sealing performance.
  2. Clean and maintain valves: Clean the valves in the hydraulic system regularly to remove dirt and impurities to ensure the normal operation of the valves.
  3. Use high-quality rubber sealing materials: Choose sealing rings and sealing materials with reliable quality and good wear resistance, high temperature resistance and chemical corrosion resistance to improve the sealing performance and service life of the valve.
  4. Strengthen the filtration and maintenance of the hydraulic system: Install high-quality filters to minimize impurities and pollutants in the hydraulic system, check and replace the filters regularly, and keep the system clean and operating normally.

In conclusion
  • Poor valve sealing is one of the main common factors that cause the oil pressure of the hydraulic system to decrease, which will have a negative impact on the stability, accuracy, and energy efficiency of the system. By regularly inspecting and replacing sealing rings, cleaning and maintaining valves, using high-quality rubber sealing materials, and strengthening filtration and maintenance of the hydraulic system, the problem of poor valve sealing can be effectively solved and the normal operation and stable performance of the hydraulic system can be ensured.
  • In addition, timely repair of poor valve sealing also requires attention to prevent further damage to other components of the hydraulic system and ensure the safety and reliability of the system. By taking various effective measures, we can solve the problem of poor valve sealing, improve the working efficiency of the hydraulic system, extend the service life of the system, and ensure the normal operation of the system.
