How to regularly inspect and maintain the pressure tank to ensure its long-term normal operation?

As an important equipment, pressure tanks are widely used in many industrial and civil fields. In order to ensure that pressure tanks can operate stably and safely for a long time, regular inspection and maintenance are indispensable. First of all, it is necessary to regularly check the appearance of the pressure tank, especially to check whether there is obvious corrosion, cracks or damage on its surface. Corrosion usually occurs where the pressure tank is in contact with the external environment, especially in areas with high humidity or concentration of chemicals. Any cracks or dents found need to be repaired in time to avoid further structural damage.
It is equally important to check the inner wall of the pressure tank. As the service time increases, sediments may accumulate or corrosion may occur inside. By regularly cleaning and inspecting the inner wall, these sediments can be prevented from affecting the flow of fluids or corroding the tank body. In some high temperature or high pressure environments, internal corrosion is more serious, so regular cleaning and inspection are essential. The cleaning process can use appropriate cleaning agents and equipment to ensure that there is no residual material inside the pressure tank that will cause performance degradation.
The pressure gauge and control valve of the pressure tank are also important parts of inspection and maintenance. First, ensure the accuracy of the pressure gauge and calibrate it regularly. If there is an error in the pressure gauge, it may result a wrong judgment of the pressure in the tank, which will affect the stability of the entire system. At the same time, the control valve needs to ensure flexible operation and no sticking. When checking the control valve, confirm the sealing of the valve to prevent leakage. Lubricate the valve regularly and check the working condition of the valve to prevent pressure control failure due to aging or damage.
For the safety valve of the pressure tank, regular inspection is also essential. The safety valve is a key component to prevent the internal pressure of the pressure tank from exceeding the set value. Once a failure occurs, it may cause serious accidents such as the pressure tank bursting. During the inspection, it is necessary to confirm whether the opening and closing of the safety valve is normal to ensure that it can be opened in time when the pressure exceeds the standard. Test the safety valve regularly to simulate the overpressure state and confirm that it can work normally.
In addition to these basic component inspections, the support and fixing structure of the pressure tank also need to be checked. The support feet or brackets should not be loose or deformed to ensure the stability of the pressure tank during use. If the support part is found to be damaged or unstable, it should be reinforced or replaced in time.
Finally, ensure the safety of the environment around the equipment, avoid substances that are prone to fire or explosion around, and pay attention to good ventilation to prevent the internal temperature from affecting the service life of the pressure tank. Regular inspection and maintenance of the pressure tank can not only extend its service life, but also reduce the chance of failure and ensure the stability and safety of the system.
