4 Points on Causes of Water Leakage in Closed Cooling Towers

Water leakage is one of the common faults of closed cooling towers. However, according to our normal thinking, most closed cooling towers are made of stainless steel or aluminized zinc plate, and the cooling water also circulates in a closed coil.

There should be no water leakage phenomenon.
Here, Xiaoju will analyze in detail why closed cooling towers leak and how to solve the problem of water leakage in closed cooling towers. Even if there is a water leakage in the cooling tower, there is no need to panic. As long as the cause is identified and solved specifically.
Most of the water leakage of closed cooling towers occurs after a long service life and aging.

If the cooling tower that has just been installed leaks during the initial commissioning or shortly after commissioning after debugging, it means that there is a deviation in the manufacturing of the cooling tower and some parts are unqualified in production.
So what are the common reasons for water leakage in closed cooling towers? Xiaoju has sorted out and summarized the reasons for water leakage in closed cooling towers, mainly including the following points:
Water leakage due to corrosion of the water collection tank
This is mainly due to long-term use.

It may also be due to the high acidity and alkalinity of the local water quality, which leads to the corrosion of the material of the water collection tank by the environment and water quality. The thickness of the tank body is uneven, and there will be damaged water leakage at the thinner place. Water leakage will increase water consumption, aggravate environmental pollution, and then accelerate the corrosion of other parts, creating a vicious cycle. If it is a glass fiber reinforced plastic closed cooling tower, we can clean the surface, polish it clean, degrease it with a cleaning agent, and reinforce it with epoxy repair agent and glass fiber tape. If it is made of aluminized zinc plate, consider replacing some aluminized zinc plates.
Water leakage at the joint of the tower body basin connection plate
When assembling a closed cooling tower, glue is used between aluminized zinc plates for compaction and sealing treatment. After long-term operation, due to the impact force of the spray water, the deformation of the basin body and the falling off of the sealant will cause water leakage at the connection. Since the spray water is concentrated in the bottom pool, water leakage requires continuous replenishment of spray water. The plates of closed cooling towers are all made of aluminized zinc plates. Sealant can be filled from the inner gap of the closed cooling tower for plugging.
Water leakage of water pump
This is very rare. In this case, contact the manufacturer of the water pump as soon as possible. Saying that water leakage of the pump will cause unstable pressure and affect the water circulation.
Water leakage of connecting pipeline
When laying pipes, some flanges and elbows will be connected. When connecting, a sealing ring will be added between the two connectors. Most of the reasons for water leakage of pipelines are that the pipeline connection is not compact, the sealing ring is damaged or the position is displaced, which will cause an insecure seal and water leakage.
