| The hose braiding machine may have some problems during production and use, some due to improper use, and some due to problems during production and operation. The specific reasons are as follows: 1. Failure of outer adhesive layer (1) Cracks on hose surface The main reason for the appearance crack of the hose is that the hose is bent in the cold environment. (2) Bubbling on the outer surface of the hose The reason for blistering on the outer surface of the hose is that the hose production quality is unqualified, or it is improperly used during operation. (3) The hose is not broken but there is a large amount of oil leakage The hose has a large amount of oil leakage, but no fracture is found. The reason is that when the hose passes through the high-pressure liquid flow, the inner glue is eroded and scratched, until a large area of steel wire layer leaks out, resulting in a large amount of oil leakage. (4) The outer rubber layer of the hose is seriously deteriorated. Micro cracks appear on the surface, which is the performance of natural aging of the hose. Due to aging and deterioration, the outer layer is continuously oxidized to cover its surface with a layer of ozone, which thickens with time. As long as the hose is slightly bent in use, it will produce tiny cracks. In this case, replace the hose. 2. Failure of inner adhesive layer The rubber layer in the hose is hard with cracks: the main reason is that the plasticizer is added to the rubber products, which makes the hose flexible and plastic. However, if the hose is overheated, the plasticizer will overflow. The inner rubber layer of the hose is seriously deteriorated and obviously expanded: the inner rubber layer of the hose is seriously deteriorated and obviously expanded because the inner rubber material of the hose is incompatible with the oil used in the hydraulic system, and the hose is deteriorated by chemical action. |
