PRODUCT HOSES
Ensure that the hose material is chemically resistant to the sprayed products and the
used fl ushing agents.
Ensure that the product hose is suitable for the pressure generated.
Ensure that the following information can be seen on the high-pressure hose:
-
Manufacturer
- Permissible operating pressure
- Date of manufacture
Make sure that the hoses are laid only in suitable places. Hoses should not be laid in the
following places under any circumstances:
- in high-traffic areas,
- on sharp edges,
- on moving parts or
- on hot surfaces.
Ensure that the hoses are never run over by vehicles (e.g., fork lifts), or that the hoses are
never put under pressure from the outside in any other way.
Ensure that the hoses are never kinked. Observe maximum bending radii.
Make sure that the hoses are never used to pull or move the equipment.
Suction hoses may not be subjected to pressure.
Several liquids have a high expansion coeffi
cient. In some cases their volume can rise with
consequent damage to pipes, fi ttings, etc. and cause fl uid leakage.
When the pump sucks liquid from a closed tank, ensure that air or a suitable gas can
enter the tank. Thus a negative pressure is avoided. The vacuum could implode the tank
(squeeze) and can cause it to break. The tank would leak and the liquid would fl ow out.
The pressure created by the pump is a multiplication of the inlet air pressure.
4.2.2
GROUNDING THE DEVICE
Friction, fl owing liquids and air or electrostatic coating processes create charges. Flames or
sparks can form during discharge. Grounding prevents electrostatic charging.
Ensure that the device is grounded. See Chapter "Grounding".
Ground the work pieces to be coated.
Ensure that all persons inside the working area are grounded, e.g., that they are wearing
static dissipative shoes.
The spray substance supply (spray substance tank, pump, etc.) must be grounded.
