General Introduction
UT2040 Hot and cold water cycle testing machine is suitable for all kinds of plastic pipes and pipe fittings according to the requirements of the standard after the assembly of the pipeline system test, the pipeline system withstands a certain internal pressure, in the specified time cold and hot temperature alternate changes, after completing the specified number of tests, check the leakage and rupture of pipes and pipe fittings.

Key Features
1, Flow display: with flow sensor, real-time display pipeline flow information.
2, Unique water flow control: the switching time from cold water circulation to hot water circulation and from hot water circulation to cold water circulation in the test pipeline is less than 1 minute, and the difference between the sample inlet temperature and the sample outlet temperature is less than 2 °C within 1 minute, and the pressure fluctuation during the switching process is less than ±0.02MPa, which is far better than the national standard requirements.
3, Good human-computer interaction:
3.1. Full-color touch screen display mode, the control system integrates pressure, flow, temperature, time control and sampling, and the system automatically draws the pressure-time curve during the test.
3.2. Every 10s, the collection of real-time test pressure, specimen entry, outlet real-time temperature, and instant flow information ensures that at least 6 data can be collected during the switching process, which is convenient for the later analysis of test data.

3.3. The upper and lower limits of the pressure and temperature alarm can be set, and the test can be stopped automatically when the temperature or pressure exceeds the upper and lower limits of the alarm.
3.4. Automatically judge the fault and give the prompt information, the running system automatically determines the abnormal fault location, and gives the corresponding prompt, even if the user has not been trained, he can also carry out maintenance by himself.
4, High reliability: The instrument design adopts industrial programmable control system, and all control systems are designed according to the application of industrial environment, and the system is safe and reliable.
2.1, Open structure: high temperature and high pressure water only exists in the specimen and its connected pipeline, the equipment is a normal pressure vessel structure, other circulation pipelines are atmospheric pressure, valve body, sensors and other devices work under atmospheric pressure, ensuring the long-term reliable operation of the instrument.
2.2, Intelligent switching: The control system automatically sets the temperature of the inlet water of the specimen pipeline, the water temperature of the outlet, the level of the cold and hot water tank, and the cold and hot water switch time, and intelligently controls the opening of the cold and hot water tank control return valve, so that most of the cold water returns to the cold water tank when the cold and hot cycles are switched, and the temperature change of the cold and hot water tanks during the switching process is less than 3 °C, and the energy consumption of the system test is low;
2.3, Low-noise operation: The water flow controller independently designed by our company is installed in the test pipeline, which greatly reduces the noise generated by the high-speed water flow washing the pipeline;
2.4, Water treatment system: There are water purifiers in the water inlets of the hot and cold water tank, which can extend the service life of parts and ensure water quality.
2.5, Refrigeration device: the imported industrial chiller is used as the low temperature cold source, and the refrigeration efficiency is improved through water-to-water cooling, so that the compressor works in the best state, which not only improves the refrigeration efficiency, but also greatly increases the service life of the industrial chiller.
2.6, Intelligent water replenishment: The intelligent water replenishment function reduces the labor intensity of the experimenter, and at the same time avoids the manual water replenishment affecting the water temperature of the test, causing temperature fluctuations and affecting the normal operation of the test.
