Hydraulic hose precautions in cold weather! Quanyi Hydraulic Encyclopedia
In relatively cold environments in winter, cracks on the outer surface of hydraulic hoses can cause the hoses to twist. Quanyi Rubber and Plastics takes everyone to understand hydraulic hoses in cold weather!
1.First of all, pay attention to observe whether there are cracks in the hydraulic hose. If cracks are found on the outer surface of the hydraulic hose, decide whether to replace the hydraulic hose immediately. Because the load-bearing capacity of the hose depends on the steel wire reinforcement layer, the steel wire reinforcement layer is the skeleton of the hose and is usually surrounded by steel wire braiding. High-pressure and ultra-high-pressure are mostly made of multiple layers of steel wire braided around the frame. Low-pressure hose is braided with cotton and linen instead of steel wire, and is mostly used in low-pressure oil return pipelines. Temperature has a great influence on hydraulic hoses.
2.Therefore, do not move hydraulic hoses or disassemble and repair the hydraulic system at will in cold environments to ensure the safety of the hydraulic hoses. If necessary, do it indoors. If you need to work in a cold environment for a long time, replace the anti-icing hose.
3.Finally, regardless of whether the outer rubber layer of the hydraulic hose is damaged or whether there are defects on the inner and outer surfaces, we need to handle it carefully to avoid small problems causing big troubles. If the hose exceeds its service life, we need to replace it in time. Don't feel sorry, and don't bury safety hazards to save money and endanger our personal safety.
