Vacuum cleaner hose

Vaccum cleaner tube,cleaner hose,flexible cleaner hose:

 Material:

Outer bore(Wall): High quality soft PVC

Reinforcement: High intensity PVC coated spring steel wire,corrosion resistant.

Structure:

PVC coated spring steel wire spiral welded to outer PVC wall.

Properties:

1. Highly flexible,anti-friction.

2. The hose can be extended and returns to normal length when released.

3. Extension Rate: 1:2,1:3,1:5,1:6 or upon request.

Temperature Range:

  -10°C to +70°C

 Applications:

1. Stretch hose for household vacuum cleaners.

2. Industrial extractor equipment:  fumes, air and light dust extraction at low pressure.

3. Automotive industry:  demist and air conditioning.

4. Sports equipment: protection for the spring and get a better apparence.

Test Equipment : Twist tester

Test Method:The length of hoses is 30±1 inches(762±25mm ), excluding installation part.Clip both ends of the sample hose to the two mandrels of the distortion testing machine,then test them at a 30±2 r/min of rotation speed till they appear fracture or to the fixed endpoint. Breakage of the hose began to tearing, perforating, or reinforcing ribs breaking, or the lining of the hose or liner damage to the circle, or above mixing circumstances. Record broken time for the first time or the cycle times when to the fixed endpoint, fracture type, ambient temperature, sample descriptions and the number of test samples.

Test Equipment: Wear test machine

Test Method:Fix a new standard 500 grit sand paper to the cylinder of wear test equipment,and then install one end to mechanical shaft of the equipment,put the other end into guide frame hanging heavy substance weighing 454±3 g,after that begin the reciprocating friction testing at a 20±1r/min speed.Avoid swing of the heavy substance during testing process.The test finishes until hose appears perforation,frazzle or to the fixed endpoint. Record broken time for the first time or the cycle times when to the fixed endpoint, fracture type, ambient temperature, sample descriptions and the number of test samples
