Overview
PNSHAR PN-DT30 drop tester is a device for free drop testing of the face, corner and edge of Encasement parts. It adopts a single-arm double-column structure, is equipped with a digital display height display and a decoder for height tracking, and can accurately give the product drop height. The error from the preset height does not exceed 2% or 10mm. The machine has the functions of electric reset, electronic control drop and electric lift, which is convenient to use; the hydraulic buffer device improves the service life, stability and safety of the machine. The single-arm design is easy to place the product, and the angle error between the drop angle Impact surface and the baseplate plane is less than or equal to 5 °.
Features
1. The single-arm double-column structure design is adopted to prevent accidental peeling due to sudden power failure, and the lift is smooth.
2. The support arm adopts an electric reset design, and there is no need to manually pull the support arm for reset.
3. The support arm adopts an electromagnet extraction structure and is assisted by a tension spring to ensure that the support arm is instantly peeling.
4. With hydraulic buffer device design, instant absorption of arm Impact energy.
5. Universal specimen holder design, can be different sizes of Encasement parts of the edges, corners and surface rapid positioning test.
Principle
The Drop Tester raises the specimen to a preset height through an electric lifting device, and the support arm is fixed by an electromagnet. During the test, the electromagnet is powered off and released, and the support arm is instantly pulled away with the assistance of a tension spring, so that the specimen can fall freely to the Impact surface. The device tracks the height through a decoder and displays it by a digital display to ensure the accurate drop height. The hydraulic buffer device is used to absorb the Impact energy when the support arm is reset.
Applications
Encasement test
Standards
GB/T4757.5、JB/T7407、ISO2248
Steps
1. Place the specimen on the universal specimen holder and position it according to the test requirements (face, corner, edge).
2. Set the required drop height through the control panel.
3. Start the electric lifting device to lift the arm and the specimen to the preset height.
4. After confirming that the height is correct, the electronically controlled drop device is triggered, the electromagnet is released, and the specimen falls freely.
5. After the test is completed, use the electric reset function to reset the support arm.
6. Record the test results.
Notice
Before use, please confirm that the power supply is AC380V 50Hz and ensure that the voltage change is within +/- 10%.
• Equipment Ambient Temperature should be 5~ 35 ℃, Humidity < 85% R.H.
