Pipe Testing Equipment with Modular Structure & Intelligent Control System for Reliable Pipeline Pressure Test Procedures
Summary:
This testing machine was custom manufactured by our company for a renowned European brand in compliance with European technical standards, and has not exhibited any technical or quality issues during years of use across Europe.
This instrument primarily consists of several major components: a cold water exchange execution module, a hot water exchange execution module, a sample chamber, and an industrial chiller. It features an aesthetically pleasing design, modular architecture, advanced technology, stable performance, reliable quality, and user-friendly operation.
Instrument failure:
1. Smart switching: The control system automatically adjusts based on the inlet and outlet water temperatures of the sample pipeline, liquid levels in the cold and hot water tanks, and the switching duration between cold and hot modes. It intelligently operates the return valves of both tanks to ensure that most cold water flows back to the cold tank during cycle switching, with temperature fluctuations between tanks remaining below 3°C, resulting in low energy consumption during system operation.
2. Low-noise operation: The test pipeline is equipped with a water flow controller independently designed by our company, significantly reducing noise generated by high-speed water flow erosion.
3. Refrigeration system: Utilizes imported industrial chillers as the low-temperature cold source, employing water-to-water cooling to enhance refrigeration efficiency and ensure the compressor operates at optimal performance, thereby improving both cooling efficiency and significantly extending the service life of the industrial chillers.
4. Flow Display: An imported flow sensor that displays pipeline flow information in real time (optional).
5. Pre-tensioning device: Features an independent rigid support frame with a lever-based prestressing mechanism, capable of displaying the loading force value in real time (optional).
6. Maintenance-free control valve: Features a diaphragm-free valve body structure with sealing material made of high-temperature resistant PPL. The valve body sealing material does not require replacement during instrument operation, ensuring maintenance-free performance and exceptional reliability.
7. Smart Water Replenishment: The intelligent water replenishment function reduces the labor intensity for laboratory personnel while preventing manual refilling from affecting the experimental water temperature, thereby avoiding temperature fluctuations that could disrupt normal experiment operation.
