1purpose：
The XJL-300 drop hammer impact testing machine is suitable for measuring the external impact resistance of various types of pipes (PVC-U water supply pipes, sewage pipes, low-pressure water supply pipes, low-pressure water supply pipes, core foam pipes, double wall corrugated pipes, PE water supply pipes) and sheets, as well as hard plastic sheets. The product complies with the industry standard JB/T9389 technical conditions for drop hammer impact testing machine and national standards GB／T14152、GB／T14153、GB／T6112； simultaneously satisfy GB／T5836、GB／T10002.1、GB／T10002.3、GB／T13664、GB/T16800、GB／T18477 According to the standard requirements for testing methods.
IIfeature
The machine adopts PLC (see Figure 1) control and text display (see Figure 2) display group.
The new control panel (see Figure 3) has simpler operation and more stable performance.
Completely bid farewell to single board computers, achieving industrial grade control and adding statistical functions.
4 LCD text facts display impact height, impact frequency, damage result, and damage frequency.
5. The upper and lower limit heights can be easily adjusted through the setting keys and number keys, and specific operations can be achieved through specific keys (see Figure 4 for the main screen and Figure 5 for explanation).
The automatic conversion speed achieved through the program ensures high accuracy, and the addition of automatic and jog functions makes it easy to zero. The system's power-off memory function enables the same sample operation to be zeroed only once, greatly improving work efficiency.
7 ensures operational safety through numerical and mechanical limits.
8 has achieved stable operation of standard cylinders through advanced photoelectric sensors to capture signals and program specific functions, thereby realizing reliable secondary impact capture function.
According to the provisions of GB/T14152, the system has added statistical functions. During the sample impact process, the system automatically calculates and judges the qualified status of the sample based on the number of impacts and damages, thus truly achieving automation.
The device adopts a double column structure (see Figure 6), which is simple, convenient, safe and reliable to operate.
The 11 sample fixture platform adopts a transmission structure of hand cranked bevel gears and standard lead screws, which is easy to operate, labor-saving, and highly accurate.
