DP-500 Flow Test Machine
Description
The DP-500 is a flow test machine capable of testing components
with a differential pressure of up to 500 bar and an upstream
pressure of up to 700 bar. The components are manually loaded into a
4 position indexer which automatically transfers them to each of the
stations in turn. The components are tested under oil to expel any
air from the internal cavities before testing to improve cycle
time. Prior to being tested the components are reverse flushed at
up to 100 bar to remove any possible contamination. Following the
test, excess fluid is removed from the component at a blow off
station where the components are blasted with a jet of air in an
enclosed chamber. The machine is capable of
delta q tests, valve out tests, full lift valve in test and variable
lift tests as well as being capable of generating flow lift curves.
The test results are stored against the component serial number
within an Excel® spreadsheet, appending
subsequent test information for the same component to the
spreadsheet. Operator interaction and feed back is via a touch
screen HMI incorporating various charting and digital transducer
read out capabilities.

Operation
The components are loaded into the indexer 2 at a time. When the guard is closed and the system is ready, the components are indexed to the first station which is the flushing station. This reverse flushes the components at up to 100 bar. The next index rotates the components to the test fixture where they are automatically clamped. When clamp pressure has been achieved the test sequence commences, only taking measurements when all the test conditions are within limits. When the test has been completed the components are unclamped and indexed to the drying station. Here they are blasted with air in an enclosed chamber to remove excess fluid. Once this has been completed the next index returns the components to the load/unload station where they are replaced with the next set of components to be tested.
