Fiber reinforced concrete drop hammer impact testing machine

CECS13-2009Fiber reinforced concrete drop hammer impact testing machine
1、 Product Introduction
Fiber reinforced concrete drop hammer impact testing machineSuitable for measuring the impact resistance of hardened fiber-reinforced concrete, it consists of an impact frame, impact ball, and impact hammer. It can also be used for impact resistance testing of other products, such as electronic products, plastics, communication products, etc. The height can be manually adjusted, and different diameters and weights of steel hammers or steel balls (hereinafter referred to as hammers/balls) can be selected.
2、 According to the standard
CECS 13-2009 "Standard Test Methods for Fiber Reinforced Concrete"
3、 Technical parameters
1. Test height: 0-1500mm (adjustable);
2. Test space: length 500 * width 450mm (the distance between the two opposite baffles on the impact frame chassis is 160mm, that is, the distance between the baffle and the surface of the specimen is 5mm, and the height of the impact frame should ensure that the center of mass of the impact hammer is 500mm away from the surface of the impact ball);
3. Impact ball: diameter 63mm, made of steel;
4. Impact hammer weight: 4kg, 4.5kg, 5kg, 5.5kg, 6kg, made of steel (standard 4.5kg);
5. Power supply voltage: 220V;
6. Total weight: approximately 50kg;
4、 Instructions for use
1. After unpacking, first place the instrument on a flat surface, and then connect the controller (the signal line is inserted into the circular hole of the controller, and the power line is inserted into the square hole of the controller). Insert the positioning light into the socket and keep it on. Adjust the position of the positioning light to be at the center point of the sample.
2. Place a circular cake shaped specimen with a diameter of 150mm and a thickness of 63 ± 3mm inside four baffles on the chassis, with a distance of 5mm from the surrounding area. Place a steel ball with a diameter of 63mm on top of the specimen, and drop the impact hammer from 500mm to impact the surface of the steel ball. (Please refer to the standard for specific operating steps)
5、 Precautions
1. Be careful not to accidentally injure personnel when releasing the ball (hammer).
2. When there is a significant difference in the position of the ball (hammer) falling, the horizontal angle of the electromagnet can be adjusted.
3. After installing the ball (hammer) on the electromagnet, shake it left and right to check if it is installed in the center position.
4. The controller can be placed on a table, wall rack, or other object of appropriate height. It is forbidden to hang or pull the signal line to prevent it from breaking.
5. Non professionals or without the manufacturer's guidance are prohibited from disassembling the equipment.
