In the industrial production process, carbon steel tube heat exchangers are widely used equipment. Its unit volume of equipment can provide a large heat transfer area and good heat transfer performance. It is mainly composed of shell, tube plate, heat exchange tube, head, baffle, etc. Because the equipment has a compact structure and can be made of a variety of materials, it has strong adaptability and is widely used in large-scale installations and high temperatures and high pressures. Therefore, we must do daily maintenance work:
1. Carefully check the operating parameters of the equipment. Over-temperature and over-voltage are strictly prohibited.
2, Operators should strictly abide by the operating procedures, conduct regular inspections of the equipment, and check whether the foundation supports are stable and the equipment leaks, etc.
3, Keep bolts tight and valves, pressure gauges and other facilities intact.
4. When using equipment belonging to pressure vessels, the following points should be done during daily maintenance:
(1) Operators should be certified to work. The user unit should conduct regular training and education for pressure vessel operators.
(2) Pressure vessel files must be established and kept by the management department. And it should be clearly stated in the process operating procedures and job operating procedures.Carbon steel tube heat exchangeroperating requirements. Its content includes at least the following points:
a.Equipment operating process indicators.
b.Equipment operating methods.
c.Items and parts that should be inspected during equipment operation, abnormal phenomena that may occur during operation and avoidance measures, as well as emergency handling and reporting procedures.
(3) When one of the following abnormal phenomena is discovered, the operator should take emergency measures promptly and follow the prescribed reporting procedures.
a.When the working pressure and medium temperature of the equipment exceed the specified values, effective control cannot be achieved even if measures are taken.
b.The main pressure-bearing components of the equipment may suffer from dangerous phenomena such as cracks, bulges, deformation, and leakage.
c.Safety attachment failed.
d.The pipes and fasteners are damaged, making it difficult to ensure safe operation.
e.The carbon steel tube heat exchanger and pipes vibrated severely, endangering safe operation.
f.Other abnormal situations.
5, Keep the equipment and surrounding environment clean.
