Detailed Product Description: | ZM-811 helmet puncture resistance testing machine, helmet puncture resistance testing machine Description: the helmet resistance to puncture test machine is the Qingdao ZHONGBANG Instrument Co., Ltd. specializing in the production of helmets testing equipment, according to the the helmet new national standard GB / T 2812 - 2006 helmet test methods, used for the detection helmet impact testing machine resistance to shock absorption properties and puncture resistance, high degree of automation, easy operation, the helmet manufacturers over the production license, Lao recognize positive and Construction quality control unit over-qualification assessment an essential testing equipment. Second, the helmet-resistant the puncture testing machine parameters 1, the force sensor: Measuring range 0-20KN frequency corresponding minimum 5kHz, dynamic force sensor, accurate to 1N. (Measured at the China Institute of Metrology identification by only of 5000HZ dynamic sensor measurement qualified to ensure the accuracy and reliability of data), the impact of the drop hammer: the impact of the drop hammer: the quality of the 5-5.01kg hammer hemispherical diameter 96mm , made of 45 # steel. Puncture steel hammer: the quality of 3-3.05kg, the puncturing part of the cone angle of 60 °, the cone tip diameter of 1 mm, a length of 40 mm, maximum diameter 28mm, hardness HRC45. (Newly developed puncture hammer, specially designed to ensure puncture cone can accurately hit the requirements in the standard position), helmet puncture resistance testing machine drop hammer height: 1000mm. Helmet puncture resistance testing machine power supply: AC220V, 50Hz. Helmet impact the puncture testing machine placement: ground, helmet puncture resistance testing machine according to the standard requirements of GB / T 2811-2007 "helmet", wearing a helmet magnesium alloy head model set in the high sensitivity dynamic force on the value of the sensor, and then the drop hammer mass 5kg from a height of 1m impact shock momentarily by the high sensitivity of the dynamic force sensor means detects the maximum force value in order to determine the helmet impact absorbing performance bad. Passed to the head-on force should not exceed 4900N the cap shell may not have debris fall off in order to pass. Helmet puncture resistance testing machine features a drop hammer and hammer to replace the simple operation. Helmet puncture resistance testing machine control box according to user preferences to adjust the position, easy to use. 3, according to the different types of adjustment of the helmet drop height. 4, LED digital display, auto-save maximum force. 5 helmet puncture resistance testing machine bench: the ability to control suspension and release the impact of the fall of the hammer, puncture drop hammer. Helmet puncture-resistant testing machine base: impact strength, can be securely attached to the load cell. 7, power alarm device: When the circuit to form a closed loop, you can send a signal, which means that the the puncture cone has contact head mode. Helmet puncture resistance testing machine impact professional precision sensors, frequency corresponding minimum 5kHz, dynamic force sensor, measuring range 2t, accuracy is ± 2.0%. Helmet puncture resistance testing machine # 1, # 2 Al-Si alloy test a head mold. In line with GB / T 2812-2006 Appendix A requirements. |
