(Summary description)The Original Analysis Of the Damage Of The High Pressure Hose Assembly
 The high pressure hose assembly has problems during use, mainly due to the following aspects:
   1. Production quality:
   1. The vulcanization of the high-pressure hose does not reach the positive vulcanization, and the manifestation is under-sulfur or over-sulfur. Due to the above two reasons, its various attributes and functions cannot meet the requirements, which leads to problems in the use process.
  2. The wall thickness of the hose is uneven, especially the inner rubber layer has the greatest impact.
3. The steel wire braiding or winding process did not follow the design process, the braiding angle did not reach 54 degrees 44 minutes, the steel wire braiding was too tight or too loose, the deformation of the high pressure hose (after pressure) (elongation, shortening or bending deformation) The amount) is larger.
  4. Poor airtightness of the outer rubber layer leads to steel wire corrosion.
  5. The inner layer of rubber has poor sealing performance, which makes it easy for high-pressure oil to enter the steel wire layer.
   6. The adhesive layer and the steel wire layer have insufficient adhesion.
   2. Blind production, no further improvement in accordance with the environmental or technical requirements, and the performance of the high-pressure hose cannot meet the specific environmental or technical requirements. This aspect is rare, but as long as it is mentioned, attention should be paid.
   Three. Quality problems of matching crimping joints:
   1. The material of the crimping joint does not meet the requirements.
   2. The process design of the crimping joint fails to meet the requirements.
   Fourth, the withholding is not in place, for example, the amount of withholding is not enough.
   5. The high-pressure hose assembly is not installed properly or installed correctly.
  6. ​​The inside of the high-pressure hose assembly must be kept clean. If foreign matter (dust) enters the pump or valve, it will affect the normal operation of other equipment and indirectly affect the high-pressure hose assembly.
