If cracks appear on the surface of the Jack Hose, they should not be ignored or left untreated for continued long-term use. During operation, the hose is exposed to hydraulic pressure and may also be affected by bending, friction, temperature changes, and surrounding environmental conditions. Once cracks appear on the surface, the integrity of the outer layer may have been compromised, so the hose should be inspected promptly.
Surface cracks can occur for various reasons. Long-term use may cause the hose material to age naturally, gradually reducing its flexibility and making the surface more susceptible to cracking. Exposure to unsuitable environmental conditions may also accelerate material aging. In addition, frequent bending, excessive stretching, compression, or continuous friction against other components may cause surface damage.
Minor surface marks should be distinguished from actual cracks. If a mark is only a shallow abrasion caused during transportation or use and has not affected the overall structure of the hose, its condition can be further observed. However, if the crack is clearly visible and becomes wider when the hose is bent, or if it is accompanied by hardening, brittleness, bulging, or fluid leakage, the condition may indicate significant deterioration.
This issue is particularly important during hydraulic jack operation. The hose is subjected to hydraulic pressure while the system is working. If the hose already has cracks, continued operation may cause the damaged area to expand. When the hose is bent, vibrated, or subjected to pressure changes, the damaged section may experience additional stress, increasing the possibility of hydraulic fluid seepage or leakage.
Therefore, when cracks are discovered, the equipment should first be stopped and the overall condition of the hose should be inspected. Particular attention should be paid to the cracked area and the connection points at both ends. The hose should also be checked for fluid leakage, bulging, abnormal deformation, and severe wear. If the cracks are deep, extensive, or accompanied by other abnormalities, continued use should be avoided.
During daily operation, factors that may damage the hose should also be minimized. For example, the hose should not be kept in an excessively bent position for long periods, and it should be protected from continuous contact with sharp metal edges. It should not be used to bear additional pulling forces or mechanical loads. Proper hose routing can reduce external damage and help extend service life.
Proper storage is equally important. A hose that remains unused for a long period may still deteriorate if exposed to direct sunlight, excessive moisture, heat, or improper compression. Therefore, suitable environmental conditions should be maintained both during use and storage.
In summary, when obvious cracks appear on the Jack Hose, the safety and reliable operation of the hydraulic system should be given priority. Continued use of a visibly damaged hose is not recommended. Timely inspection, assessment of the extent of damage, and appropriate corrective action can help reduce the risk of fluid leakage and hose failure during operation.
