Emergency repair methods for high-pressure hoses

Emergency repair methods for high-pressure hoses:
1. Bonding method: When the rubber hose with a hydraulic system pressure between 25-8.0MPa ruptures, the bonding method can be adopted: Wipe the area around the rupture of the hose clean; apply “anaerobic” on the rupture of the hose. “Glue”, “epoxy resin” glue, “801” glue or “502” glue (the length of the glue is about 2-3 times the length of the broken part); wrap it with tape or canvas strips in a stacked manner Apply 4-5 layers of glue (each layer should be coated with glue); tie the two ends of the wrapped tape and canvas strip into a tight knot; wait for it to solidify for 15-20 minutes before use.
2. Bundling method The bundling method is suitable for emergency repairs of rubber hose rupture with a pressure below 16MPa. The specific method is: apply one of the glues commonly used in engineering machinery to the ruptured part of the hose; wrap 2-3 layers of oil-resistant rubber with a width 2-3 times the length of the ruptured part (each layer should be coated with glue) ); use No. 12 iron wire to tie the wound oil-resistant rubber; wait for it to solidify.
3. Bone-setting method When the rupture part of the rubber hose is large or about to break due to external force (shrapnel breakdown, extrusion rupture) or system overload, the bone-setting method can be used: wipe the ruptured part of the hose clean and cut off the ruptured part. ; Insert the homemade steel “bone” into the cut hose (in particularly urgent cases, a steel pipe with the same outer diameter as the hose bone diameter can also be used as the “bone”); use a homemade steel plate clamp to connect the hose and “bone” “Bone” clamp (when the situation is particularly urgent, No. 8 iron wire can be used instead of the homemade steel plate clamp); clean the connected hose before use.
4. Reconstruction method Since the pipe joints of each rubber hose in the hydraulic system are different, and high-pressure or ultra-high-pressure ruptured hoses should not use the “bonding method”, “bundling method” or “bone-setting method”, accordingly, you can adopt Reconstruction method: saw off the pipe joint of the ruptured hose; find a replacement hose with a pressure-bearing capacity and length similar to that of the ruptured hose, and saw off its pipe joint; weld the angle of the pipe joint of the ruptured hose to the replacement hose Above; clean the welded hose before use.
