Selection
Note
①Please control the pressure fluctuation below the maximum operating pressure. If the pressure fluctuation exceeds the maximum operating pressure, it may cause the piping to fly off, the joints and piping to rupture.
②When using fluororesin in fluids and environments with rapid temperature changes, the deformation of the pipe may cause airtight leakage and pipe pull-out, so an inner bushing should be used.
③The amount of dust generated by the KQB2 series is related to the use conditions and environment. If you are worried about the impact on the machine maple and loading, please first confirm the amount of dust generated in the actual
machine, and then determine whether it can be used.
For the KQB2 series products, the internal pressure change causes the parts to slide, which may cause dust generation. In addition, after the elbow, 3-way, and long elbow are threaded, the rotation to fix the position may also cause dust
generation.
Install
Note
① Use the mounting holes to fix the right-angle pipe, T-shaped pipe, and Y-shaped pipe.
If not fixed, the tensile force and torque generated by the weight of the product may cause leakage and damage.
② After the elbow, 3-way, and long elbow are threaded, they can be rotated to fix the position, but rotation is not allowed during use. Otherwise, metal powder will be mixed into the fluid due to friction, or the joint will be broken.
③ During use, please do not shake or twist the pipe.
Pipe loading and unloading operations
Note
① Installation of the tube
1) The KQB2 series does not use a lubricating tire. Therefore, the insertion force during tube installation becomes larger, especially when the polyurethane tube is inserted due to its softness, the tube may bend. Hold the root of the tube and
insert it securely until you feel a contact. The tube insertion length is roughly based on the M dimension in the external dimension drawing.
② Tube detachment
1) Tubes used at high temperatures and tubes used for a long time have an enlarged outer diameter and may no longer be installed on the quick-change connector. Tubes that cannot be installed should be discarded and replaced with new ones.
