Hoses do not allow proper flow, pressure, or range of motion.
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.
Detectable evidence may include:
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.
