The seal ring of hydraulic bolt tensiler plays an important role. If the sealing environment is not good, it will cause many faults.
What is the function of the seal ring of the hydraulic bolt tensiler?
The sealing ring of the hydraulic bolt stretcher directly determines the quality of the stretcher. When drawing, the hydraulic oil must be sealed below 150 mpa, and no extrusion or trimming is allowed. The seal of hydraulic bolt stretcher is usually cut by imported polyurethane material, and the size of the seal is unlimited.
If the outer diameter is 90.25 and the inner diameter is 46.8, the oil containment pressure area can be obtained quickly without further calculation by engineers and field operators. Ultra-high pressure seal adopts self-excitation seal. According to the strength and allowable deformation range of cylinder block, the greater the pressure, the better the sealing effect, and the more general the oil resistance, aging resistance, extrusion resistance and strength.
Every time the hydraulic bolt stretcher is used, the internal debris should be cleaned up to keep the equipment clean.
After completion of construction, regular maintenance, wiping of equipment and oiling of bending die should be carried out in accordance with the requirements of the manual.
