Highly Automated Drop Hammer Test Equipment for Impact Resistance of PVC and Plastic Pipes

• Intelligent Control System: Adopts PLC control and a touchscreen operation interface, boasting a high degree of automation. It enables digital presetting and real-time display of key test parameters (impact height, hammer lifting, and hammer dropping), ensuring intuitive and efficient operation.
• Reliable Secondary Impact Prevention: Equipped with a pneumatic transmission system, it achieves 100% secondary impact suppression--effectively avoiding interference from redundant impacts and guaranteeing accurate test results.
• Comprehensive Safety Protection: Integrated with automatic personal safety protection mechanisms, including sample door interlock protection , fully safeguarding operator safety during test procedures.
• User-Centric Design: Features user-friendly operation, stable reliability, and an ergonomic structure. With proven performance, the instrument has been exported to key markets such as Europe and North America, gaining wide recognition from global customers.

The tester is equipped with a multi-layer safety protection mechanism to ensure operational safety:

• 1st level: Sample door interlock protection;
• 2nd level: Observation window interlock protection;
• 3rd level: Upper and lower limit position protection.

Powered by a high-torque stepping motor, the tester achieves a lifting speed of up to 250 mm/s--enabling the hammer to reach a height of 2 meters from 0 in just 8 seconds. This significantly shortens the test cycle and improves operational efficiency.

Adopting a multi-stage speed control program, the tester ensures smooth hammer stopping and precise positioning with zero deviation. This advanced control logic eliminates inertial displacement, guaranteeing consistent test conditions.

The drop hammer guide pipe is optimized via 3D modeling, integrated with exhaust holes to minimize wind resistance during hammer drop--ensuring stable and repeatable impact force. Additionally, a hoop reinforcement structure is added to the pipe to prevent structural failure and deformation, enhancing long-term operational reliability.

Abandoning traditional electromagnetic hammer mechanisms, the tester adopts a high-force pneumatic structure:

• Equipped with 300N long-stroke dual air cylinders for powerful and stable operation;
• Features a rubber tendon plate hammer surface to ensure non-damaging impact and consistent contact with samples;
• The pneumatic hammer releasing/lifting design fundamentally eliminates issues such as cable bending, 
• Incorporates a pneumatic automatic locking structure for enhanced safety and reliability.

• Mechanical structure: Adopts standard aluminum alloy profile assembly, achieving process standardization, modular installation, and a lightweight yet high-strength design;
• Electrical system: Configured with a 7-inch touchscreen and Delta PLC, ensuring intuitive operation, stable performance, and easy maintenance.

All core components are sourced from renowned brands:

• Air cylinders: Adker;
• Touchscreen & PLC: Delta;
• Power supply: Taiwan Mean Well.

Comprehensive safety protections are integrated across electrical, mechanical, and software systems, including: leakage protection, short-circuit protection, anti-static protection, anti-interference protection, pressure leakage protection, power failure protection, and misoperation protection--fully complying with international safety standards.

The tester supports full-automatic test processes, including automatic zero-point calibration, automatic hammer lifting, automatic hammer releasing, and automatic test execution. This minimizes manual intervention, reduces human error, and improves test efficiency and data consistency.
