The pressure in the cooling circulating water system drops rapidly

2016-12-11View Original

Thread Content

In winter, the pressure in the cooling circulating water system drops very quickly; water needs to be added every half hour at night. Leaks have also been checked, and there are basically no leaks. Also, the bog compressor (water-cooled) was turned on before, and that helped a bit, but for some reason, we can’t stop the circulating water now; I don’t understand why this is happening. Is there a solution? Help, thank you!

We’ve never encountered such a situation here; however, since the water needs to be replenished every half hour, we still need to find the source of the leak.

1. Check for gaps, examining them one by one. 2. Check the discharge points to see if, for winter anti-freezing purposes, circulating water is discharged from certain stations. If you only put in money without taking any out, it will cause bloating; if no bloating occurs, part of the insurance amount can be withdrawn

The amount of water that needs to be added in winter should be less than in summer. We have automatic control for the liquid level in the water tower; do you set it to automatically add water when the liquid level drops? The higher frequency of water replenishment than before is probably due to leakage into another system. 1. Has the amount of wastewater discharged increased? 2. Check whether there are any abnormalities in the process systems, especially in the heat exchangers that use cooling water, and whether there are any issues with the liquid level in the condensate tanks below. 3. There should be a flow meter for the water replenishment volume; check whether there are any abnormalities in the amount of water added, as well as whether there are issues with the water supply valve.

To prevent freezing, we disconnected all the equipment that wasn’t necessary, and the water was drained from the equipment

We are in closed mode; currently, the pressure in the cooling water circulation system is dropping rapidly. To prevent freezing in winter, all unused equipment is disconnected, and it has remained that way since then.

After the equipment was disconnected from the circulating water, was the circulating water drained this time to prevent freezing? Check for any internal leakage.

If water needs to be replenished frequently, it’s necessary to check for internal leaks in the pipes; water is left running continuously to prevent freezing

There may be an internal leak in the heat exchanger; it’s worth checking. Such leaks are quite hidden and generally not easy to detect

It’s possible that the circulating water has drained for some unknown reason, causing the pressure to drop, but no leak could be found.
