The SL-HY is a versatile testing apparatus designed to assess the resistance of thermoplastic pipes to short-term hydraulic bursts under constant internal water pressure at a fixed temperature. This device is ideal for thermoplastic pipes used in fluid transportation and can accommodate various pipe specimens effectively.

The SL-HY incorporates an embedded PC controller (IPC) and follows a modular design. Each module, consisting of up to 30 stations, is equipped with its own microcomputer. These microcomputers receive commands from the central PC, control the pressure, collect data, and continuously provide feedback to the PC via a serial bus. The system intelligently recognizes the dimensions and material of the specimen, offering an optimized pressure increase solution and algorithm tailored to each test. For pipes with significant expansion rates, it provides rapid pressure ramp-up while maintaining stability at a constant temperature.

The central PC gathers test data, analyzes outcomes such as leakage or rupture, and offers functionalities including specimen pre-treatment, real-time monitoring, test data storage, power-off data protection (memory), and data restoration upon power-up.

Key Features:

1. Integrated Functionality: Boasts features such as specimen pre-treatment, real-time monitoring, test data storage, power-off data protection (memory), and automatic data recovery upon repowering.

2. Intelligent Recognition: Intelligently discerns the size and material of the specimen, offering an optimal pressure increase solution and algorithm tailored to each test.

3. Adaptive Pressure Control: For pipes with a high expansion rate, provides a rapid pressure increase and maintains stability at a constant temperature.

4. Enhanced Solenoid Valve: A self-developed solenoid valve significantly extends its operational lifespan and eliminates the need for further maintenance.

5. Multilingual Interface: A user-friendly display interface that supports multiple languages to address the needs of customers worldwide.

6. Comprehensive Protection: Incorporates protective measures spanning electrical, mechanical, and software aspects to ensure robustness and safety.

7. Data Retention: The pressure control unit retains testing data for up to 7 days, even when offline.

8. Software Interface: [Details about the software interface, such as ease of use, data visualization, or customization options, would be provided here.]

9. Intuitively display control: The 24-inch industrial tablet computer control allows for the simultaneous display of experimental curves on multiple interfaces.

The Pressure Supply Unit plays a crucial role in the testing apparatus, responsible for delivering and maintaining the necessary pressure required for accurate and reliable test results. It is designed with several key features to ensure optimal performance and safety during operations. Some notable features include:

1. High Pressure and Capacity: Engineered to handle both high-pressure requirements and substantial capacity demands, suitable for a wide range of pipe specimens and testing scenarios.

2. Automatic Water Compensation: Incorporating an advanced water compensation system, automatically replenishes water to prevent damage to the pump due to insufficient water levels, ensuring continuous and uninterrupted operation.

3. Low Noise Operation: Designed with noise reduction in mind, operates quietly, minimizing disruption in the testing environment and allowing for more focused monitoring of tests.

4. Comprehensive Protection System: Equipped with a robust protection system, safeguards against electrical leakage and water shortages, offering an additional layer of safety for both operators and equipment.
