Reasons why the circulating water for workshop equipment does not circulate for cooling,
Thread Content
There is a water tank 2 meters underground, and a pipeline pump is used to transport water to a workshop located 200 meters away. The inlet pipe has a diameter of DN65, while the return pipe has a diameter of DN125. This system is used for cooling the equipment in the workshop (5 medium-frequency heating furnaces). The pipes near the equipment are cold, but the equipment itself does not cool down. The water returns to the tank at the end of the return pipe, where it is released into the open air; there is also normal water return, but still no cooling occurs. What could be the reason for this, and how can it be fixed?
What was the situation with the water pressure drop last time, the air release from the water system, and the heat exchange surfaces?
Is there a problem with the valve, is there a short circuit in the return water flow, and is there water hammer?
Check the return water temperature; if the temperature difference between the inlet and outlet of the cooler is small, it may be due to scaling.
The circulating water pipeline is probably clogged with air; try to release some air
Friend, I’m very interested in this question. Are there any pictures? The heat exchange efficiency is poor; I only consider the impact of scaling. Could you be more specific regarding the process? Are there any pictures I can use to learn from?
1. What is the water inlet pressure of the equipment? What is the return water pressure? 2. What is the inlet water temperature of the equipment? Return water temperature? 3. Is there air resistance inside the device? 4. Are the pipeline valves functioning properly and unobstructed? 5. Check whether the cooling equipment is clogged? 6. Do the pump’s flow rate and head meet the requirements? 7. Are the inlet and return water pipes up to standard?
Without data, it’s impossible to make a judgment; ultimately, by drawing a graph and marking out each parameter, everything becomes clear at a glance.
