1、 Instrument Overview
The XGH-63 plastic pipeline system hot and cold water circulation testing machine is suitable for inspecting the leakage of various pipes and fittings after being assembled according to the specified requirements and subjected to internal pressure for a specified number of times of temperature alternation. This instrument is mainly used for pipeline system testing after the assembly of pipes and fittings. Standard Test Methods for Thermoplastic Pipe and Fitting Systems Applicable to Cold and Hot Water Systems.

2. Pressure control accuracy: set value ± 0.05MPa (there is no water hammer phenomenon during cold and hot water alternation)
3. Switching time between hot and cold water: less than 1 minute
4. Each cycle of hot and cold water: 15 minutes
5. Number of cycles: Any setting between 1-10000.
6. Temperature indication error: 0.5 ℃
7. Temperature uniformity inside the constant temperature bath: ≤ ± 1 ℃
8. Temperature control range: Cold water: 15 ℃~Room temperature Hot water: Room temperature~95 ℃
9. Applicable pipe diameter: ¥ 63
10. Number of test stations: 6 channels
11. Power supply: 380VAC/220VAC mixed use
12. Standard rated power: 25kW
13. Instrument size: 5550mm x 2800mm x 1800mm
14. Instrument installation size: 8000mm x 7000mm x 1800mm
Advantages: 1. The design principle ensures the reliability of the instrument. During the test operation, high pressure is generated in the sample pipeline, while other parts of the instrument maintain normal pressure.
2. Energy saving design limits reduce experimental operating costs.
3. Equipped with comprehensive protective devices, the instrument will automatically shut down in case of abnormal situations.
