Shenzhen University: 25 joule pendulum impact testing machine project renovation
Shenzhen University purchased a manufacturer's 25J plastic pendulum impact testing machine 5 years ago, due to product quality problems, there are large pendulum shaft friction, pointer back to zero serious out-of-tolerance problems。
Wanyi upgraded it, the pointer type was upgraded to the liquid crystal type, the Angle sensor was added, and the pendulum bearing was replaced。
The main features after the transformation:
1, wide operating space, operation is very convenient
The pendulum support is a single column structure, and this support is located at the back of the machine, so that the operation space is very wide;At the same time, it also provides convenience for later installation of low temperature impact accessories。
2, very low friction resistance, the air strike absorption work to the minimum
A shafeless encoder is used to collect the swing Angle of the pendulum. There is no friction when the shafeless encoder rotates, and the friction resistance of the machine is only the friction resistance of the two bearings of the pendulum shaft and the wind resistance when the pendulum falls, so that the friction energy loss is minimal。
3, the resolution of digital display is 20 times that of analog display
The Angle resolution of the encoder is 0.At 045°, energy resolution is better than 1/2375。
4, the support is tight and reliable, and can be quickly replaced。
Sweep for immediate attention
