JM-1Safety helmet impact puncture resistance tester

1Safety helmet impact puncture resistance testerintroduce

Developed according to the national standard GB/T 2812-2006 "Test Methods for Safety Hats", it is used to test the impact absorption performance and puncture performance of safety helmets. It is widely used in special labor protection equipment supervision and inspection stations, building science research institutes, construction engineering testing stations, power departments, and safety helmet production enterprises.

IIdetailed parameters

Impact hammer: with a mass of 5-5.01kg, the hammer head is hemispherical with a radius of 48mm and made of 45 # steel

Puncture cone: with a mass of 3-3.05kg, a cone angle of 60 ° for the puncture part, a cone tip diameter of 1mm, a length of 40mm, a maximum diameter of 28mm, and a hardness of HRC45

● Hammer height: 1000mm, adjustable hammer height

● Force measurement system: using a dynamic force sensor with a measurement range of 0-20KN, a corresponding frequency of 5kHz, a full range of ± 2.0%, and an accuracy of 1N

● Equipped with 1 # and 1 # aluminum silicon alloy test special head mold each (in accordance with the provisions of Appendix A of GB/T 2812-2006)

The release point of the electromagnet can be adjusted up, down, left, right as needed

● Bench: Control the suspension and release of impact hammers and puncture hammers through automatic electromagnetic attraction

● Base: It has impact resistance and can firmly install force sensors

● Puncture alarm device: When the puncture cone contacts the contact mold, the equipment will sound a horn alarm and flash a light to prompt

LED digital display, accurate to 1N, automatically saves the maximum force value;
