Winston Engineering Case Study 2

Case Study 2

Title: Pump performing below expectation

Findings & Observation:

1. Pump cannot achieve it duty point.

Possible causes on the findings and observations:

1. Filter regulator under size

2. Air hose under size

3. Needle valve under size

Solution and Conclusion:

1. Connect to 3/4" filter regulator achieve 80% of actual flow rate and pressure.

2. Connect to 3/4" filter and needle valve can only meet 30% of actual flow rate and pressure.

3. Connect test bay 1" air hose direct to diaphragm Pump can meet the flow rate and pressure.

Recommendations:

1. Up size the filter regulator from 3/4" to 1"

2. Remove the needle valve. The needle valve only have 6mm orifice size on air outlet. It restricted the air output.

3. Up size the air hose from 3/4" to 1"

Pump install with 3/4' air hose

Pump with 3/4" Filter regulator & needle valve

Pump with 3/4" Filter regulator & needle valve

Up size air hose from 3/4" to 1"
