Leakage
Cause
The seal at the hydraulic hose joint is damaged, which may be caused by long-term use, wear, aging or improper installation. The hose body is broken, which may be caused by hose quality problems, long-term high-pressure impact, external mechanical damage, aging, etc. The pipe clamp is loose, causing the hose to move during operation. Then the seal at the joint fails.
Consequences
Hydraulic oil leakage will cause the pressure of the hydraulic system to drop, affecting the normal operation of the system and reducing work efficiency. Leaking hydraulic oil may also pollute the working environment and increase maintenance costs. If the leakage is serious, it may cause equipment shutdown and affect production progress.
Blockage
Cause
Impurities, contaminants or moisture in the hydraulic oil accumulate in the hose. It may be caused by failure of the hydraulic oil filtration system, poor tank sealing or impurities entering during maintenance. The aging and shedding of the rubber inside the hose or the damage to the inner wall of the hose to produce debris can also cause blockage.
Consequences
Blockage will reduce the flow of hydraulic oil. Make the actuators (such as hydraulic cylinders, hydraulic motors, etc.) slow, weak, or even unable to work properly. It may also cause abnormal increase in system pressure and damage to other components.
