qualified hydraulic oil
The choice of hydraulic oil with good quality appropriate trademark can help prevent bubbles appearing in the hydraulic oil during operation. The selection of hydraulic oil should be based on meeting the relevant technical requirements, referring to the local temperature, according to the standard of the oil gauge for refueling. Also, keep the hydraulic system clean. The oil quality, oil level oil color of hydraulic oil should be checked frequently. If foam milky white is found in the hydraulic oil, air is mixed in the hydraulic oil. The source of air should be carefully checked new oil replaced. If high water-based hydraulic oil is used, a high hydraulic tank should be provided to increase the pressure on the inlet of the hydraulic pump, which helps to prevent cavitation of the cylinder.
appropriate hydraulic oil additives
Choosing the right hydraulic oil additive can effectively prevent the turbidity hydration of the hydraulic oil, prevent the occurrence of foam, stabilize the quality of the hydraulic oil, ensure the long-term normal operation of the hydraulic oil.
Prevent excessive oil temperature reduce hydraulic shock
The reasonable configuration of the hydraulic oil radiator can prevent the temperature of the hydraulic oil getting too high. If the oil temperature in operation is too high, the cause should be found cleaned in time to eliminate the bubble in the hydraulic oil. In addition, when working in the hydraulic system, avoid repeatedly increasing the engine throttle, try to run smoothly to reduce the impact of hydraulic oil on the hydraulic components.
Install repair hydraulic cylinders properly
When installing repairing the cylinder block, piston rod other major components of the hydraulic cylinder, it should be installed according to the lower limit of the standard tolerance, which can well reduce the occurrence of cavitation. If the hydraulic cylinder components cavitation phenomenon, can only be used to remove cavitation polishing method surface scale, ordinary fine sandpaper can be used for polishing treatment.
