what is the hydraulic bolt Manifold Block

The principle is relatively simple hydraulic bolt, namely the use of a conical configuration in the axial direction parher hydraulik monoblock under the action of force, the bolt holes and the taper sleeve is generated in an interference fit, screw completely eliminate the gap, to achieve precise positioning. In addition, the use of powerful hydraulic tensile tensile bolts, operate according to specifications, can be controlled accurately bolt tightening force, to achieve high coupling precision. The whole process does not appear to carry any force of the situation, you can tighten the nut hand, will not bolt, nut and screw to cause any damage. Just two or three people, one day, can be installed or removed Ends 12 bolts.
Hydraulic bolt technical parher double connector difficulties mainly in high pressure hydraulic pumps, hydraulic components and conical bolts and processing of the drogue. For the overall system reliability and security, and is currently the hydraulic part is completely imported equipment, and this equipment has been used on domestic and imported units. Hydraulic bolt the possibility of damage is very small, it is because the coupling sleeve and the initial value of the clearance holes up to 0.08 ~ 0.10mm, penetration holes very easy. The swelling of interference, each subjected to a uniform load of the bolt, not subjected to excessive shear forces. Even after long-term operation, it is not affected by the damage. Demolition, parher bsp port tapered screw to fasten it is easy to quit, and then shrink sleeve, back to the initial gap value, you can easily remove the drogue
