IEC 60529 IPX3 to IPX6 Spray Nozzle Hose Nozzles Testing Equipment
System overview:
The test system is used to verify the protective performance of the enclosure for electronic and electrical products, automobiles, motorcycle parts, household appliances, seals and lamps under water jets at degree IPX3, IPX4, IPX5 and IPX6.
This IPX3~IPX6 spray nozzle and hose nizzle test system ensures that the water spray speed reaches the standard required value by controlling the water supply flow, the enclosure is sprayed from all practicable directions with a stream of water from the standard test nozzles as shown in IEC 60529:2013 figure 5 and 6.
It is composed of nozzles holder, turntable, intelligent water supply and control system, one IPX3/4 spray nozzle, one IPX5 hose nozzle and one IPX6 hose nozzle.
The intelligent water supply and control system consists of a water supply tank, a water supply system, and a control system. The test water supply flow is controlled by PLC, frequency converter, and turbine flow sensor. The test flow rates according to the standard requirements have been default in the control system, as long as the operator selects the waterproof test level on the touch screen, the test can be performed. And the test flow rates can also be set by operator.
