Overview
ZKHS SC-020 sand dust test chamber is mainly used for IP5X and IP6X two levels of test specified in the shell protection class standard, suitable for dust and dust resistance test of various auto parts, test parts include lights, meters, electrical dust jacket, steering system, door lock, etc., and inspection of product sealing.
Features
1. Adopt imported PLC program to control the LCD controller, and display working hours in full Chinese.
2. Equipped with "Schneider" AC contactor, switch, button and "Panasonic" time relay, dust socket.
3. The time of the dust blower is automatically alternated, and the dust blower, dust vibration and total test time can be controlled separately.
4. Adopt closed alloy low-noise motors and multi-blade centrifugal fans to ensure efficient circulation.
5. Dust heating system with stainless steel mica heating jacket.
6. Provide multiple safety protections such as leakage, short circuit, overtemperature, motor overheating, and overcurrent.
Principle
The dust test chamber is controlled by PLC program to automatically perform alternating work between the blowing fan and the dust vibration to simulate the dust environment. The circulating fan drives the dust flow, the heating system maintains the dust temperature, and the vacuum system cooperates with the pressure gauge and the filtrating device to ensure the stability of the test conditions to test the dust performance and sealing of the product.
Applications
Auto parts dustproof and dust resistance test, product sealing inspection
Standards
GB/T4208-2008、GB/T10485-2007、GB/T2423.37-2006、GBT4942.1-2006
Steps
1. Connect the power supply and ensure that the voltage is AC380V +/- 10% 50Hz three-phase five-wire system.
2. Set test parameters, including blower time, dust vibration time, and total test time.
3. Start the equipment, and the PLC controller automatically controls the dust blower and vibrates alternately.
4. Monitor the test process and observe parameters such as working hours through the LCD display.
5. After the test is completed, turn off the equipment and clean the dust.
Notice
• Power frequency check meets AC380V +/- 10% 50Hz requirement before use.
• Make sure the Vacuumpump is specified and connected correctly when ordering.
• Regularly check safety protection functions, such as leakage, short circuit, overheating, etc.
• Avoid overloading during operation to prevent the motor from overheating.
• Clean the dust inside the equipment in time after the test to keep it clean.
