The inside diameter of the swing pipe is 15mm. The sample rotating table diameter is 1000mm (Or other size according to the diameter of the swing pipe), and the height is adjustable. The rotation speed is 1~5rpm which controlled by PLC panel.
• Waterproof Jet Test Device (JL-56): With water supply device size is 1000x1000x600mm, the nozzle diameter is ф6.3mm (IPX5 waterproof test ) and ф12.5mm (IPX6 waterproof test). The water speed is 12.5 ±0.626L/min for IPX55 and 100 ±5L/min for IPX6

• Immersion tank Waterproof test Device (JL-8): It is for IPX8 test. It can simulate a water depth of 0~50m. The water immersion tank diameter is 600mm and the height is 1200mm. The compressive stress is 10 atmospheres or design according to customer‘s request.

IP Waterproof Test Machine JL-56

Q1: The chamber makes unusual sounds or other abnormalities when it starts up and cannot operate normally
A1: Please make sure that the voltage and frequency of the connected power supply are consistent with the product nameplate. Otherwise, the device may be damaged.

Q2: After powering on, the touch screen displays a phase sequence error
A2: JL-56 power supply is three-phase electricity. If the phase sequence is incorrect, the equipment cannot operate normally. Please turn off the equipment, then swap the phase sequence of any two phases of the power line, that is, the connection order, and then turn on the equipment again.

Q3: The turntable will rotate during the test. Will it cause the power cord of the sample to get tangled?
A3: The turntable we designed will only rotate in one direction when the sample does not need power supply. When the sample needs power supply (click “Sample Power Supply” on the touch screen), the turntable will automatically change the direction of rotation every minute without causing the power cord to get tangled.

Q4: I can hear the pump starting and the flow meter is on, but no water is coming out of the nozzles
A4: Please stop the water pump first, then open the air evacuation valve as shown in the figure below, wait until water flows out and then close it. Then restart the water pump.

Air evacuation valve

Note: The latest JL-56 no longer has an air evacuation valve. It has been redesigned so that the equipment can be used normally as long as there is enough water in the water tank.

Q5: After clicking Start Test, the equipment does not start testing
A5: Please make sure the program is in the initial state. Please click Zero Reset and then click Start Test again.

Q6: How to confirm test results?
A6: If the sample short-circuits and shuts down during the test, it is definitely not in compliance with the standard. If the sample can still start and run normally, you need to take out the sample, wipe off the moisture on the surface, and then open the sample to check whether there is water inside. If there is water, it is also not in compliance with the standard.
For specific details, different industries have different rules, and you can refer to the corresponding industry standards.

Q7: It was normal during the IPX5 test, but it prompted water shortage during the IPX6 test.
A7: IPX6 requires much more water than IPX5, which is 100L per minute. If there is not enough water in the water tank, the program will prompt that there is a lack of water. Please add enough water to the water tank to ensure that the test can proceed normally.
