Kitagawa BBT200, Instruction Manual

Page: 38 / 50

・
Attach the manual switching valve at a position where it is easy to operate for the
attaching equipment.
・
Install the hydraulic unit at a position where the drain hose is not kinked and the needle
of the pressure gauge is easily read.

・
When other actuators are operated by the same hydraulic pressure source as
the cylinder for chuck, be sure that a pressure drop of the cylinder does not
occur during use. A hydraulic pressure drop leads to a drop in the gripping
force which could allow the work to fly out.
・
As to the drain hose
・
Use one with inside diameter
φ
32.
・
Use a transparent vinyl hose for visualization.
・
Provide a stream slope, without air pocket. This will ensure no back
pressure.
・
The end of the hose is physically above the oil level. (Refer to Fig.13)
・
If the hydraulic oil stagnates inside the cylinder, oil leakage occurs, which may
cause a fire.
・
Install after removing the dust inside the pipe completely.
・
Add a filter to the pressure supply line. If foreign matters gets inside the
cylinder, this is dangerous since the rotation valve of the cylinder will seize,
the hose will tear off, and the cylinder will rotate. This is also dangerous as the
work will fly out.
・
Always use a flexible hose for the hydraulic piping to the cylinder, and the
bending force or tensile force of the pipe must not be applied to the cylinder.
Use a pipe inside diameter as large as possible and keep the piping length as
short as possible.
・
Especially, when a large sized hydraulic unit is used, excessive surge pressure is
generated and the gripping force becomes large, therefore, it may result in breakage
of the chuck or the lowering of endurance. Restrain the surge pressure by adopting
a throttle valve, etc.
