Shell And Tube Heat Exchangers are widely used in industrial production. Keeping them in good operating condition is very important for improving efficiency and extending service life. Daily maintenance work cannot be ignored.
First, regularly check the inlet and outlet temperature and pressure changes of the equipment. If the temperature difference is found to be smaller or the pressure is abnormal, it may be internal blockage or leakage, and the cause needs to be promptly investigated.
Secondly, pay attention to whether the shell and connection parts of the shell and tube heat exchanger are corroded, deformed or leaking. If there is any abnormality, the machine should be shut down for inspection and maintenance immediately to prevent the problem from expanding.
Lubricating parts such as valves and flange connections should be regularly filled with lubricating oil to ensure flexible switching and avoid operating difficulties caused by jamming.
Dirt and sediment inside the heat exchanger should also be cleaned regularly. Physical cleaning or chemical cleaning methods can be used to keep the heat transfer surface clean and improve heat exchange efficiency.
Finally, use the equipment strictly in accordance with the operating procedures to avoid over-temperature and over-pressure operation. Irregular operation will accelerate equipment aging and affect safety and performance.
Through the above daily maintenance measures, the stable operation of the Shell And Tube Heat Exchanger can be effectively guaranteed, the downtime of failure can be reduced, and the overall production efficiency can be improved.
