The middle and late stage and sudden failure of hydraulic equipment

The hydraulic equipment runs to the middle stage, which belongs to the normal wear stage and has the lowest failure rate. At this stage, the hydraulic system has the best luck, but special attention should be paid to regularly replacing the hydraulic oil to control the pollution of the oil. The wearing parts begin to show normal out-of-tolerance wear one after another. At this stage, the failure rate is high, the leakage increases, and the efficiency decreases. In view of this situation, the hydraulic components should be comprehensively inspected, and the failed hydraulic components should be repaired or replaced. In order to prevent the hydraulic equipment from being unable to operate and being shut down.

Sudden failures mostly occur in the early and late stages of hydraulic equipment operation. The fault is characterized by suddenness, the area and cause of the fault are more obvious, the collision occurs, the inner spring of the component is suddenly broken, the pipeline is ruptured, the foreign body is installed, and the seal is damaged.

Sudden failures are often directly related to improper installation and maintenance of hydraulic equipment. Destructive failures also sometimes occur due to operational errors. The main measures to prevent such failures are to strengthen the daily management and maintenance of equipment, and strictly implement the post responsibility system to strengthen the business training of operators.
