Dual valve hydraulic system

hydraulic systemMost faults do not occur suddenly, there are usually signs such as noise, vibration, impact, crawling, pollution, air pockets, and leaks. If these phenomena can be detected in a timely manner and appropriately controlled and eliminated, system failures can be eliminated or relatively reduced. The following are several common faults and troubleshooting methods in hydraulic systems.

Hydraulic system leakage: Hydraulic system leakage is divided into internal leakage and external leakage. System leaks can affect the performance of hydraulic components, increase energy consumption, and pollute the environment. There are several reasons and troubleshooting methods for system leaks.

(1) The system pressure adjustment is too high. Under the same conditions, the higher the pressure of the system, the greater the possibility of leakage. Therefore, the pressure of the system should be adjusted to the optimal value according to the requirements.

(2) Too many oil pipe joints, loose screws on the pipe joints, and loose screws on the joint surfaces or sealing surfaces. Reduce oil pipe joints and bends, and tighten loose screws.

(3) Improper selection, damage, aging, and improper assembly of seals can all cause leaks. Reasonable selection of various sealing devices, timely replacement of aging and damaged seals with new ones, and re adjustment and assembly of those with assembly deviations.

(4) Excessive oil temperature not only reduces the viscosity of the oil and increases leakage, but also accelerates the aging of the seals, causing serious system leakage. Strictly control the temperature of the hydraulic system. In order to improve the heat dissipation of the system, a cooler can be added or the heat dissipation performance of the oil tank can be improved.

Technical requirements for dual valve hydraulic system:

1. Before assembly, all components need to be sorted and cleaned thoroughly

2. Assemble when conditions permit, and tighten all fasteners without any looseness during assembly.

3. The length can be customized according to specific customer needs or based on on-site craftsmanship.

4. Unqualified products must be strictly controlled and not assembled.

5. After assembly, the overall appearance is beautiful and clean.
