Definition
Hoses do not allow proper flow, pressure, or range of motion.
Description
Hoses provide the fluid (air, oil, water, etc.) flow path for movement,
cooling or signal transmission.
The following is a basic list of hose characteristics that must be
considered for proper equipment function: length, diameter, flexibility,
material and color.
- Diameter: If the diameter is too small, there may be a restriction
in the flow and increase in the pressure drop, and fitting issues
may occur. If the diameter is too large, flexibility and fitting issues
may arise.
- Flexibility: If the hose is too stiff, range of motion may be reduced.
- Material: If the wrong type (hydraulic, air etc.) is used, rupture
or fluid contamination may occur.
- Color: If the hose is color coded, incorrect substitution may cause
maintenance issues.
Detection
Detectable evidence may include:
Significance
Quality, Workplace Issues, Cost, Downtime, Maintenance, Throughput (cycle
time; PPH), are all potentially affected by this condition.
Throughput: Cylinder movement may be delayed
due to restrictive hoses.
Subordinate Cause
- Correct hoses unavailable
