Fouling ,plugging and leakage is the failure reasons of the column tube cooler
Column tube cooler is a kind of heat exchange equipment used, but sometimes, failure, affect the work, according to the experience summary, fouling and plugging, leakage is the major failure modes of the column tube cooler.Here is to analyze with everybody.
A, scaling
Cooler fouling can reduce heat transfer coefficient, serious blocking plate channel, thereby affect the use of the equipment.So column tube cooler should not be used in a dirty or easy scaling of the environment, and made from did not soften the cooling water medium, operating temperature should be controlled under 50 ℃.
Second, congestion
Port clearance of the cooler (2.5 to 6.0 mm), small diameter greater than 1.5 to 1.5 second stuff easy blocking, lead to equipment failure due to congestion.So in setting coarse screen pack or medium inlet flushing device, can effectively prevent the equipment of congestion, improve the effect of heat transfer.
Three, seal failure, lead to leakage
Cooler will leak under normal circumstances, in addition to the product itself, also related to the system pressure and temperature of dramatic change.Impact the instantaneous pressure drop caused by the often 2 to 3 times higher than normal pressure, the installation of the rubber gasket displacement, lead to seal failure.So in use to avoid shock phenomenon in a system, according to the condition of operating pressure increase 1.5 2.0 times the design pressure of the equipment, pay attention to the change in temperature, etc.
So among the tube cooler in use process should pay attention to these problems, try to avoid failure, cause needless loss.
The above: What are the factors affect the wind cooling effect of the cooler
