Hose Torsion Tester: Precision Testing for Stainless Steel Corrugated Hose Durability
The Hose Torsion Tester is a specialized instrument engineered to evaluate the torsion resistance of stainless steel corrugated hoses used in gas appliance connections. These hoses play a critical role in ensuring safe gas flow, making their ability to withstand repeated twisting and torsional stress essential for preventing leaks and ensuring long-term reliability. The tester subjects hoses to controlled rotational forces, simulating real-world conditions such as installation adjustments, vibrations, or accidental twists. Equipped with an LCD touchscreen control system, it automates the testing process and stops automatically once the preset number of cycles is reached, ensuring consistent, repeatable results.
The tester strictly adheres to GB/T 41317-2022, the Chinese national standard specifying requirements for torsion resistance testing of stainless steel corrugated hoses for gas appliances. This compliance guarantees that test results align with industry safety benchmarks, making it an indispensable tool for manufacturers, quality control teams, and regulatory bodies ensuring product safety.
Premium Engineering
Crafted with exquisite machining precision and a unique industrial design, the tester prioritizes both functionality and user experience. Its robust frame and high-quality components ensure stability during high-cycle torsion tests, while ergonomic details—such as easy access to hose mounting points and clear status indicators—simplify operation and maintenance. This attention to engineering excellence ensures the tester can withstand continuous use in demanding industrial environments.
Intelligent Control System
The integrated PLC (Programmable Logic Controller) and HMI (Human-Machine Interface) large-color LCD touchscreen form the tester’s operational core. The intuitive interface allows operators to set test parameters (torsion angle, speed, cycle count) with minimal training, while real-time displays of cycle progress, torsion angle, and pressure readings keep users informed throughout the test. Support for digital adjustments eliminates the need for manual calibration, reducing errors and streamlining workflows.
Precision Motion Control
- High-Performance Servo System: Equipped with a high-torque servo motor and driver, the tester delivers precise regulation of torsion angles, ensuring each twist adheres to the exact -90°～90° range specified in GB/T 41317-2022. This accuracy is critical for replicating real-world stress conditions.
- Closed-Loop Speed Control: A self-adjusting closed-loop system maintains stable torsion speed (30 cycles/min, with digital adjustability) even as hose resistance changes during testing. This stability prevents speed fluctuations that could distort results, ensuring consistent force application across all cycles.
Reliability & Safety Features
- Power Failure Memory Function: In the event of a power outage, the tester automatically saves the last completed cycle, allowing users to resume testing without restarting—minimizing downtime and preserving data integrity.
- Automatic Cycle Termination: Once the preset cycle count (0~9,999,999) is reached, the machine stops immediately, eliminating over-testing and protecting both the hose specimen and equipment.
- Gas Safety Controls: For tests requiring gas pressure simulation, the system includes ventilation/exhaust management and automatic gas source shutdown when specified air pressure thresholds are met. This prevents gas buildup, enhancing workplace safety.
- Safety Protection Door: A reinforced safety door encloses the testing area, shielding operators from moving parts and potential hose failure during high-stress cycles.
