FUNCTIONAL TEST
6.1
FIELD-TEST PREPARATION
Re-assemble pump and other components on trolley or wall-support. Connect suction and
HP hoses, test gauge, spray gun with suitable nozzle.
SIHI_0117_GB
WARNING
Overpressure!
Risk of injury bursting components
➞
Ensure that the pressure range of all the test components used
lies above the maximum operating pressure of the pump.
6.2
DEAD POINT TEST
Fill pump, hose, gun with test fl uid:
Use 0.6 MPa; 6 bar; 87 psi input air, allow pump to cycle slowly (hold gun open with nozzle
under fl uid level).
Stop pump at change-over points, check for pressure drop. There should be no signifi cant
less of pressure after change-over
Pilot valves may blow at change over.
Aids:
Flow controller
6.3
PUMP RUNNING-IN
Allow pump 0.7-0.8 MPa; 7-8 bar; 101.5-116 psi to cycle with gun open (Raise operating
pressure to maximum).
So pump cycles around 15-20 cycles/min (DS) / min
For 10 minutes
Control cycle rate with tip size. After test, check tightness of fi ttings see chapter 7.2.
Test conductivity between piston and pump housing: <100 k
Attention, this test is
-relevant.
Aids:
Test stand with adjustable fl ow
Test medium oil
Torque wrench
Ohmmeter
